|Year||Location||Styrene Level||Special Notes|
|2018||Moncton, NB (Canada)||nr||MEDIA REPORT: News report says “the smell isn’t a risk to public safety” that is due to a resin from sewer lining project. The city statement said “the process only should last a total of 24 hours as the resin cures in the sewer pipe, and the sewer workers are aware of the situation and working on mitigating the issue by replacing manhole covers with grated catch basin covers to help alleviate odour”. The city also recommended to ensure p-traps are properly sealed.|
FOIA/MEDIA REPORT: Firefighters responded to a report of a gas leak around 8:00 AM at city hall; Employees inside city hall reported smelling a chemical odor, a paint thinner odor, in the building and called 911; Upon arrival, responders ordered the evacuation of city hall as a precaution; No hazards were detected on monitors, but an odor was present. Fire department recognized a similar smell was coming from manholes; The Chattanooga Fire Department determined that a subcontractor for the city's stormwater division had been spraying styrene to line the stormwater pipes underground; Fumes spread through the pipes and into some openings for the pipes underneath city hall; The Fire Chief said that while the styrene the workers used can produce very noticeable fumes, it is non-toxic and does not present a danger to the public. No one was hurt.” Public works responded with 2 crews to flush the lines so that the smell could dissipate. Once that was completed and the building was checked again, all parties were allowed to return.
The mayor issued a public statement: “[City Hall Building] has closed for the remainder of the day, out of an abundance of caution for its employees and any visitors. The building will reopen on Monday….” Also reported was "Last night, a contractor for the city began work on a process called cured-in-place-pipe. Cured-in-place pipe (CIPP) is a trenchless rehabilitation process used to repair existing pipelines using a resin (styrene). On rare occasions during the installation process, a distinctive resin-like odor may be detected. The odor will dissipate with exposure to fresh air and there are no residual health effects.'" Parts of the area were blocked off to the public during the investigation while crews from Moccasin Bend Wastewater Treatment Plant ran water through and vented the sewer lines to clear any off-gassing from the CIPP process.”
The fire department was called back to the building later in the morning with occupants complaining of throat irritation and headaches from the smell. Responders discovered that the smell had returned. Fans were then used to apply negative pressure to the manholes until public works could respond back to the scene. Once public works personnel arrived on the scene, City Hall was closed at 1:00 PM to allow public works to properly ventilate the drains and give the building time to allow the smell to dissipate
|2018||Florida, Sarasota||nr||PERSONAL COMMUNICATION: In March 2018, Sarasota county government had a contractor line a 48 inch diameter pipe of the stormwater system. Styrene based resin was used by contractor. This contractor had conducted other jobs for the county using the same CIPP process. A nearby resident complained of odor through December 2018. The city, when they visited the site in December, confirmed the odor characteristic was similar to that of CIPP. “The odor comes and goes and some county government field inspectors cannot smell it.” In December, the city contacted Purdue University and wanted to know the cause and whether or not there is a health risk to the resident. They also wanted to know about inexpensive field tests they could use and what are the typical signs that the liner has not fully cured. The city reached out to the State, however, they did not have any field meters.|
|2018||Virginia, Salem||nr||FOIA/PERSONAL COMMUNICATION: The Fire Department responded to a two story house because of reports of a strange smell. The crew entered with a Q-rae3 (after fresh air cycle) [this is a 4-gas meter]. The homeowner stated that the smell was in the basement and that it started all of a sudden. Firefighters started getting a smell when they entered basement, and it didn’t seem like a natural gas or electrical smell but more of a like spray adhesive, paint type, or maybe dry drain. Several basement rooms had the smell, but the smell seemed to be coming from the unfinished part of the basement. Responders walked the throughout the basement and nothing was picked up on the Q-rae. The resident had an old bathroom that they no longer used, and when firefighters opened the door the smell seemed stronger. The resident had several plastic grocery bags balled up and sitting in sink. Responders picked one up and it seemed like what they had been smelling. Firefighters advised the homeowner of findings and suspected the smell was coming from the sink drain. Resident stated they would pour water, open windows, and let the basement air out. Firefighters advised the resident that no harmful readings were on the monitor. The homeowner called the fire department about 1 hr later to advise that there was a construction company doing work in neighborhood on some water pipes and using some kind of chemical in pipes and that was what the smell was coming from.|
|2018||Montreal, QB (Canada)||nr||PERSONAL COMMUNICATION: Building inhabitant in Montreal Canada requested information from Purdue University “about safety of the gas emitted from the resin of CPP processes.” The city contracted out the task of retrofitting a sewage line underneath the person’s house. The … house filled with styrene gas and associated compounds during the three-day process of curing the pipe. A month later, person still smells styrene coming from an unsealed part of the old stone house foundation and claimed it was worse in cold weather. “It’s not as intense as it was, but it gives person headaches and makes person dizzy throughout the day in his own home, even at low concentrations. This is very upsetting and unpleasant to the person.” Person asked: “How worried should I be about the health effects? And how long is it likely to leach gas from the soil under the foundation?”|
|2018||Mississippi, Hattiesburg||nr||PERSONAL COMMUNICATION: Mississippi Department of Transportation (DOT) worker visited a steam CIPP worksite and did not approach exhaust emission point that closely. Steam was not added for the first 30 minutes, instead just air blown through the chemical tube. DOT worker got a headache. DOT worker say visible emissions from the exhaust emission point where CIPP workers were standing. Respiratory protection was not observed on CIPP workers.|
|2018||Washington, Vancouver||nr||MEDIA REPORT: An odor permeating the air around Riverview Elementary School in Vancouver reportedly caused two teachers outside for playground duty to become sick. Once emergency responders arrived, they were treated and taken to a hospital. Teachers felt faint, dizzy, had nausea and vomited. Before going to hospital teachers complained of a solvent smell, itching in their nose and throat, dizziness, and gagging. Firefighters and medics responded after receiving reports that a smell was causing problems for some of the teachers. Nearby roads were shutdown. The school had students shelter in place and the HVAC system was turned off. Responders were approached by a representative of the city who declared emissions from nearby contractor who was relining a sewer pipe 600 ft away from the school. Contractor, when approached by responders, did not have an MSDS. Responders reported that the contractor was installing a resin a nearby pipe and their system was blowing a plume of gas 30-50 ft into the air. Also noted that the plume emitted would change direction regularly and would lay low near the ground. Firefighters stated that when the inverted atmosphere lifted, the emissions dissipated. Workers were asked if the process could be stopped if needed and contractor said no. Contractors said they perform the jobs regularly and were surprised to hear about issues at the school. Firefighters used a “PID” and 4-gas monitor to test air around the school and didn’t find anything. They concluded that an air inversion caused the styrene from the work crew lay low near the ground. The school superintendent reported that the teachers were outside for several hours and may have been exposed for a long period. Students also noticed the smell, but none reported being bothered by it. CIPP contractor was working nearby. Fire Department hazmat responders believed that a gaseous substance created by the steam treatment wafted toward the school. Fire Department noted the smell of styrene, described as heated Styrofoam. Hazmat crews monitoring the air around the school. Contractors working in the street were interviewed and had no complaints. Firefighters reported the workers had no evidence of symptoms.|
|2018||Massachusetts, Weymouth||“High readings, 6500 ppb”||
FOIA: Fire department with medical assistance responded to an Early Childhood Development School. Upon arrival, the custodian complained of light headedness and chest pains. Firefighters wore full PPE with SCBA. Personnel observed an acetone type odor in the area. The area was evacuated. A “4-gas meter” was used and did not respond. A new meter was brought onsite (RAE 3000 ppb meter) and fire fighter reported “high readings” up to 6000 ppb. Fire department concluded that the odor was from pipe sealing resin that was being used nearby for sewer pipe repair.
A second complaint was also called in and the fire department responded. Odor in basement was detected. Testing by fire department indicated 4500 ppb. Assumed it was “steam and smoke” being injected into pipe relining nearby by a contractor who was working with city. Fire department concluded an illegal sump pump connection in the basement allowed odor to enter the building.
MEDIA REPORT/PERSONAL COMMUNICATION: Resident and US Forest Service workers were reportedly exposed to emissions. At Federal building a city contractor doing CIPP work discharged a cloud from a manhole cover 6 ft from a building passive air intake vent. Around noon on the day of the incident, the contactors activated their product and a cloud came out of manhole about 6 ft away from the federal building. The building is 1 of only 2 places in the US to make seed available for all US government agencies, and primarily involves “seed extraction.”. It's a light industrial factory environment (10 employees), emissions went into passive vents that entered interior filtration system (which typically handles indoor dust), some people in facility people were wearing respirators at the time, but other people smelled it. Employees stated the cloud was quite large and enveloped the outside of the warehouse and strong smell inside. 2 of the 10 had some of the symptoms of initial exposure runny eyes/nose and sore throat, 1 persons called in sick for their subsequent night job. USFS thinks 20-40 minutes of exposure before building was evacuated. Federal workers submitted DOL CA-2 worker compensation claims for the incident. All employees were dismissed from work and did not return to work for 4 days. CIPP contractor provided USFS the MSDS for the resin product (not materials emitted or final CIPP). The resin MSDS reportedly contained styrene, titanium dioxide, quartz and numerous proprietary organic peroxides. Federal agency was concerned emissions may adsorbed to filters in the building and worried about chemical exposure to workers. Federal agency purchased and installed all new filters (50) for the building for concern some chemicals may have been trapped on them. The same contractor that was cited by the resident below was involved in the USFS incident. City and contractor claimed to USFS the cloud (from CIPP) is not a problem.
A nearby resident was also reportedly exposed during the same project. “The resident began noticing gases being discharged at the construction site, took pictures while standing nearby. The resident experienced nausea, a loss of hearing, headache, confusion and other symptoms, and she went to a hospital. The city’s plant interceptor line, a reinforced concrete pipe built in the early 1980s, runs along the back boundary of their land, and they granted the city a temporary construction easement to allow access during repairs. Instead of excavating the pipeline, city staff opted to use a process called a cured-in-place pipe. The Bend City Council in June approved a $5.5 million contract with a CIPP company that’s specialized in cured-in-place pipes for more than 45 years. Construction began in September and is expected to wrap up by July 2019. This method is faster and cheaper than digging up the existing line and building a new one. It also means the city doesn’t have to stop sewer access at any point. According to the legal notice, the resident began noticing gases being discharged at the construction site near her home on Nov. 10. She drove over on the adjacent canal road and took several pictures while standing about 20 feet from the manhole. She also tried to talk to workers on-site, but they hid as she approached their vehicles, according to the notice. After about five minutes at the site, the resident returned to her car to drive home. During her drive, she experienced nausea, a burning sensation in her ears, nose and throat, ringing in her ears, a loss of hearing, headache, hypertensive blood pressure and confusion, according to the notice. She sealed her clothes in a bag and went to the emergency room at St. Charles Bend, where she was diagnosed with carbon monoxide poisoning, according to the notice.”
|2018||Michigan, Midland||nr||FOIA/ PERSONAL COMMUNICATION: On July 18, 2018 residents discovered a strong odor in their home. One inhabitant went to the basement, realized odor was stronger, and reported that they felt like their eyes started burning. The other building inhabitant reported the exposure made them sick such as nausea and gave headache, which lasted for almost a week. They reported the odor smelled like industrial strength contact cement. The building inhabitants called 911 and 911 operators recommended they evacuate. Once outside they noticed about 60 yards from their house workers seemed to be in street. Fire chief, 3 fire trucks, police, and a representative of local chemical company responded. Emergency responders confirmed a strong odor in the house and in the nearby storm drains. Firefighters got no result from their “5-gas meter” or “gas-trac.” A building inhabitant was told they could go to the hospital, but this person did not for concern about the state of the property and their pets were still inside. Emergency responders found that about 2-3 city blocks away workers were lining a sewer. Responders were told by the contractors that “the odor would get worse before it gets better” and the fire department should “fill the drains with water to prevent odors from getting into the house.” Responders told building owners that they talked to workers who said the chemicals were due to lining sewer lines. The fire department filled drains with water and used fans to help expel chemicals from the home. One building inhabitant went to neighbor’s home who had young child to warn them. When visiting their neighbor, no odor in that house was reported. A representative of DOW arrived onsite and conducted air testing the house and found “VOCs in air at 2.3%.” Fire Department advised residents to stay out of the house until the odor dissipated.|
|2018||New York, Bronxville||nr||MEDIA REPORT: During 2017 Halloween evening children walked by CIPP installation site near a school. Air smelled like model airplane glue. Air monitoring was not conducted because it was not ordered to be conducted according to a statement by the school superintendent.|
|2018||Hawaii, Honolulu||nr||MEDIA REPORT: “Building management at One Archer Lane got numerous complaints Tuesday night about an unusual smell coming from sewer work on South King Street. The city claimed small amounts of the chemical "styrene" are released during construction but does not pose a significant health risk. The city also claimed that someone exposed to the chemical for a long period of time can experience headache, nausea, dizziness, and lightheadedness. Sewer work was to continue from during the evening through tomorrow morning the day the complaints were made.”|
|2018||Virginia, Richmond||nr||MEDIA REPORT: It was estimated at least a dozen residents were exposed by chemicals associated with CIPP work. “Just opening the door to come down here in the basement was like getting hit in the face with it,” described a resident, “It really would be like putting your head in a can of rubber cement. It’s sort of that headache, get a kind of woozy feeling,” she added. Employees at a nearby business described the same strong odor and symptoms: “It just gave us sort of a light-headed feeling, …it really would hit you as soon as you walk in the front door. The inside was sort of thick with this intense smell. It was really unpleasant.” “We want people coming into our businesses feeling safe and welcomed. We don’t want them to come in like is my health at risk?'” An employee of a restaurant that was also impacted vomited after breathing too much of the odor. A health inspector investigated the restaurant and recommended to increase ventilation. A city councilor was involved in the investigation along with the utility, local and state health departments.|
|2018||New York, New York||nr||
MEDIA REPORT/ PERSONAL COMMUNICATION: Numerous complaints of odors associated with nearby CIPP sanitary sewer lining activity. Utility declared “our HAZMAT staff have been called to homes complaining about these odors where we have done relining, which can be strong, and the readings they have taken never showed the presence of component chemicals of concern in the resin used like VOCs above the maximum safe level allowed.” The notice provided to residents created by the DEP declared “Odors released during the lining process may smell similar to modeling glue. These odors, though unpleasant, are not dangerous or toxic. You may alleviate by ventilating the area”. The city utility (Department of Environmental Protection DEP) city health department were involved. A New York State Assemblyman legislative aide indicated the 20 ppm of styrene was the most stringent exposure limit for residents. [NOTE: 20 ppm is a worker exposure limit for styrene and not designed for the general public].
A resident self-surveyed people located on the block in affected buildings. The following list of symptoms reported by the self-surveyed residents were: Headache, eye irritation, soreness in throat, tight feeling in throat, respiratory irritation, feeling dopey, feeling stupid, feeling sick, watering of eyes, burning in eyes and nose, nausea, coughing, itching, dried out and sore nasal passages, throat burning, sensitive eyes. The complete set of the comments from both surveys are below. The data is from two surveys sent out by a resident after each of the two days the CIPP contractor was on the block, March 6 and March 15. The surveys were sent to a mail list that has been used to assess mosquito impact and has a consistent set of responders of about 60-70 individuals representing a cross section of 21 of the 36 townhouses on the block and all 6 of the large apartment buildings. These two odor surveys had 65 responders with an almost universal overlap with the consistent responders to the Mosquito Survey.
Comments Reported by the Resident in an email to the New York City Health Department:
"No odor" responses were largely from the 6 apartment buildings with high floors.
|2017||New York, Nyack||nr||MEDIA REPORT: Residents called 911 and complained of dizziness due to strong odor that caused by sewer work near the neighborhood. Police, fire department, and ambulances personnel responded in two separate instances to reports of strong smelling burning plastic and airplane glue odor. The city sewer official suspected it was caused by a nearby CIPP activity. One resident complained of dizziness and was administered oxygen.|
|2017||California, Dublin||nr||MEDIA REPORT: 50-year-old of 8,000 feet concrete pipe was being rehabilitated using CIPP. The project manager declared that the smell residents detect is plastic that’s curing. She said the smell isn’t hazardous, but advised residents close-up their windows and doors if they smell it. The project manager called it an odor inconvenience. A couple residents complained to the utility when the liner was being installed near their homes.|
|2017||Indiana, Anderson||nr||MEDIA REPORT: 3,500 feet of existing sewer line was rehabilitated. During CIPP installation, a bypass sewer line was installed, but local water pollution control department got few calls about the odor problems in houses at basement drains. Contractor said “they have not been too many problems, and the problems we encountered are normal for a project this size”.|
|2017||Pennsylvania, South Heights||nr||MEDIA REPORT: Several residents were evacuated from 12 homes due to their contamination by an epoxy odor from a nearby CIPP project. Residents reported a gas smell and were told to evacuate. Firefighters used large fans to remove air out of homes then residents were permitted to return. The general manager of municipal authority said “P-traps should have prevented odor, but many homes did not have P-traps affected by the smell”. Utility said they have never seen so many homes affected in the same area.|
|2017||California, San Diego||nr||MEDIA REPORT: 36 elementary school students fell sick due to nearby CIPP construction site that was in process of pouring resin. Emissions entered first-grade school wing and playground area. Students said there was “fume smelling, and everyone started to cover their mouth and nose, smelling cause headache, Ambulance brought one student to the hospital. HAZMAT team was called. City spokesperson declared at a press conference that “the material being used was not hazardous. There’s no reason to believe it’s hazardous. We have crews doing this for years.” The following day the department of public works suspended planned CIPP activities.|
|2017||Missouri, Lee's Summit||nr||MEDIA REPORT: Residents expressed concerns to the CIPP contactor and utility. A liquid solution, Eco-Sorb, was offered to pour down floor drains to minimize odors. The residents were advised to open windows and doors to ventilate their homes and MSDS sheets/information about the products used during the CIPP process was provided by the contractor. Utility staff went door to door to follow up with residents to address any outstanding concerns. “We responded twice to the area for calls to 911 complaining of an odor,” said Lee’s Summit Fire Department Assistant Chief. “Each time there were no hazards found. When anyone called the business number to complain about the odor or get information on who to contact, if they had any kind of physical complaint, they were asked if they needed an ambulance. Everyone declined.” An informational video on the CIPP process was posted on the City’s YouTube site (www.youtube.com/watch?v=RxRxi87pqFE), but was removed after Purdue University researchers notified the city some of the statements the engineer stated in the video were false.|
FOIA/ MEDIA REPORT: On August 3, 2017, at 11:17 AM Fire Department responded to request of a business to investigate an odor. Fire Department learned the building inhabitants reported a chemical odor originating from floor drain in the bathroom. The responders reported they used a 6 gas meter and found no readings. Emergency responders recommended the building inhabitant pour water down the drain and believe the odor was caused by water and sewer pipe lining in the area.
On August 3, 2017, at 6:38 PM Fire Department responded to request of homeowners who complained of an odor of gas. When onsite, Fire Department explained that building occupants reported a chemical odor in the house. Fire Department checked residence with 5 gas meter and got no response, but odor was present. Some emergency responders stated a 6 gas meter was used. Emergency responders believe odor originated from contractor sewer lining activity in the neighborhood earlier in the day. Responding units vented the house.
|2017||North Carolina, Charlotte||nr||MEDIA REPORT: Office building evacuated due to odor and persons self-reporting adverse health effects. Private industrial hygiene testing company conducted PID sampling. Building was evacuated for 2 nights. Emissions were suspected to have entered through a nearby air handler outside the building due to nearby CIPP sanitary sewer installation.|
|2017||Toronto, ON (Canada)||0 ppm||“During installation of lining from MH-5 to MH-6 we received 2 complaints of odor from properties located to the west of the main entrance. Readings were taken inside the properties with the GasAlertMicro5 PID and recorded levels of 0 ppm.”|
|2017||California, Dublin||nr||MEDIA REPORT: “A couple of residents to called the utility and complained about the smell on Tuesday when the liner was being installed and cured.” The curing process is what causes the plastic smell which the project engineer says isn’t hazardous. But they are advising people to close up their doors and windows if they smell it.|
|2017||New York, Whitesboro||nr||MEDIA REPORT: Some residents noticed a bad smell in their homes; Commissioner of Water Quality and Pollution Control advised those exposed to “go outside and contact the project manager on site because the smell indicates a bigger problem within the residence.” Commissioner stated that “it means that there’s an air gap in your house from the sewer; you’re supposed to have traps inside the house — it’s a water barrier between you and the sewer,” he said. “If somebody’s getting odor inside their house, that means either they don’t have a trap or there’s a dry trap somewhere allowing that odor to get in.” The lining process was cheaper than digging up the streets, which cost about $150 per foot compared to the $30 to 40 per foot to line the pipes. Commissioner explained the process as: “We’re basically making a fiberglass pipe inside the existing one. The way you do that is you have what’s almost like a felt sock and it’s impregnated with resin. You snake that down through the pipe and you blow either steam or hot water into the pipe and it brings the sock out to full capacity on the inside of the pipe and then the hot water or the steam cures that resin. So now what you’ve made is basically a pipe within a pipe.”|
|2017||Missouri, Columbia||nr||FOIA: April 25, 2017 a person called 911 to report hearing a loud pop, smelled an odor, and saw a person down in a ditch. Upon arrival Fire Department smelled a strong glue type odor. Observer explained to Fire Department “white smoke” was coming out of the ditch and the person was no longer visible. Fire Department personnel then went into the ditch and found white smoke was coming out of a sewer manhole from a pipe placed there. The Fire Department’s combustible gas monitor showed normal readings. Fire Department met up with the sewer contractor about 100 yards from the open sewer manhole, and the contractor stated they were flushing and lining the sewer pipes, and there was no problem. Fire Department then contacted the observer who was the person who called and told them there was no problem.|
|2017||California, South Pasadena||nr||FOIA / MEDIA REPORT: The fire department was called to an adult school after 9 people reported feeling ill including “nausea.” After the fire department arrived, 2 persons continued feeling ill and were transported to the hospital. The fire department reported that the incident was “related to an odor from CIPP fiberglass sewer pipe lining that was being performed in the City system. Hazardous Materials experts responded and determined the smell was non-toxic, non-carcinogenic and was an odor only.”|
|2016||Missouri, Bolivar||nr||FOIA: January 26, 2016 fire department responded to a multifamily dwelling due to an odor report.

After rechecking residence where HCN monitor found 16 ppm, responders concluded they may have had a false positive. After two affected residences were ventilated, department personnel left.|
|2016||Wisconsin, Darlington||nr||FOIA: EMS, police, and fire departments responded to a residence where person complained of chemical odor in their home. Odor determined to have originated from sewer lining project two blocks away. Landlord was notified their plumbing traps had dried out or had faulty plumbing. Police department then issued a notice of “noxious odors” on their Facebook account. The Department stated “there is a company working on sewer lines in the city is using a resin-type substance to make some repairs. If a home is not properly plumbed or a sewer trap is dried out, it is possible the fumes will come into the home. If this happens, put water down all your drains to make sure all your sewer traps are full. The fumes cannot come into the home if the traps are full of water like they're supposed to be. Ventilate your home by opening windows and using fans.”|
|2016||Indiana, West Lafayette||nr||Fumes entered a University campus office building through floor drains; chemicals were generated by a nearby CIPP sewer pipe repair activity; building inhabitants complained to the University safety department and onsite CIPP contractor about odors; doors were opened to ventilate building before the safety department representative arrived to investigate; fire department was not called; University safety department conducted spot PID testing after building ventilation; contractor stated there was no health risk just an unpleasant odor.|

|2016||New York, Cheektowaga||nr||Resident complained “it automatically takes your breath away. You're like what is that smell?” The Cheektowaga resident said it's coming from a silvery liquid that settled in her basement sump pump. It stems from sewer work performed by a company called Insituform last week. The letter also said homeowners might experience an odor. Resident said “I woke up in the middle of the night sick to my stomach from it.” Resident said she contacted Insituform and they did come and check out the problem. But, she said it hasn't been resolved.

|2015||Massachusetts, Weymouth||nr||FOIA: Numerous concerns reported to a local elected official in 24 hours about MWRA sewer work being conducted. Release of gas reported and residents took and sent video of the construction activity to the elected official. Official asked city “What exactly is being spewed right now? Residents are claiming its styrene and a strong odor is being reported.” City also received call from residents and told resident the odor is styrene, is harmless for people and pets, and likely entered building due to faulty resident plumbing. Elected official asked why workers are not wearing protective gear and the city responded that the worker doesn’t come into contact with resin. Elected official also stated noise and odor at night caused by this activity was awakening residents. City said “contractor cannot stop in the middle of a relining segment pipe you have to go to completion". City officials communicated with one another that a Facebook video shows “steam exhaust” used to cure the liner not styrene gas. The liner does use a styrene based resin, and at times odors can be noticeable, however at very low concentrations. The workers follow their company’s health and safety plan to work with the materials.”|

MEDIA REPORT: Odor from a city sewer project drifted through pipes and into a branch of St. Anthony's Hospital on Thursday morning, forcing employees and rehabilitation patients to evacuate the building for several hours, authorities said. The St. Petersburg Fire Rescue hazardous materials team arrived at the fourth floor of the St. Anthony's Hospital Resource Center at 9 a.m. after a foul smell was reported and a hospital employee had trouble breathing, said Lieutenant. About 40 people were evacuated from the building at 500 Dr. M.L. King (Ninth) St. N, which houses an adult day care for senior citizens and a patient rehabilitation center, as well as several hospital employees' offices. HAZMAT originally thought the odor came from a ventilation problem within the hospital. Firefighters thought chlorine fumes from a rehabilitation pool were pushed onto the fourth floor, but St. Petersburg Fire Rescue was not satisfied with that explanation. The employee who was having trouble breathing was treated at the hospital.
In another incident in April 2001, fumes from an CIPP job caused a several hour evacuation of about 40 people many of them older people from a branch of St. Anthony's Hospital. The resin, when activated by hot water that is pumped in, gives off a smell like a newly manufactured fiberglass boat, CIPP Contractor officials say. One woman in the hospital was treated for breathing problems. Odor from one CIPP job baffled the hazardous materials team in April, when 40 people were evacuated from St. Anthony's Hospital for four hours. The hazardous materials team originally believed the smell was caused by chlorine from a hospital rehabilitation pool. "Yeah, that was us," said the division manager of wastewater maintenance for St. Petersburg, who added that the hospital's P-trap should have caught the smell.”
|1993||Texas, Austin||nr||MEDIA REPORT: Seven people were overcome by fumes when a ventilator at a stormwater line in stopped working and vapors escaped from a manhole. The injured, employees at the Austin Travis County Humane Society, were taken to Brackenridge Hospital after complaining of nausea and dizziness. Fire Department's hazardous material unit said the fumes contained an alcohol and benzene mixture. Industrial waste control supervisor for the city's water and wastewater utility department, said a private contractor hired by the city to coat the surface of stormwater lines near the intersection caused the accident. "What we think happened is they ran water down the line and the water reacted with those chemicals and caused the vapors," said spokeswoman for the city's water department. The CIPP contractor had workers underground at that site coating the pipes with resin when a ventilator nearby stopped working. The Humane Society workers were overcome by fumes when they removed the manhole to find the cause of an odor, fire officials said. Executive director at the Humane Society said 30 dogs in kennels near the manhole were moved to another site.|
