What eye protection should be employed when working with trichloroethylene?
Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA’s eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
How do you test for trichloroethylene?
TCE can be measured in exhaled breath up until a few hours after exposure. Special equipment is needed. Typically your indoor air testing is more useful to determine how much TCE you are being exposed to. TCE breakdown products can be measured in your urine for a week or two after exposure.
What is the LD50 of trichloroethylene?
Oral, rat: LD50 = 4920 mg/kg; Skin, rabbit: LD50 = >20 gm/kg; Skin, rabbit: LD50 = 20 mL/kg; .
What is the niosh recommended exposure limit for TCE?
NIOSH: Recommends that exposure to occupational carcinogens be limited to the lowest feasible concentration. ACGIH: The threshold limit value (TLV) is 10 ppm averaged over an 8-hour workshift and 25 ppm as a STEL (short-term exposure limit).
What products contain trichloroethylene?
It is used primarily to make refrigerants and other hydrofluorocarbons and as a degreasing solvent for metal equipment. TCE is also used in some household products, such as cleaning wipes, aerosol cleaning products, tool cleaners, paint removers, spray adhesives, and carpet cleaners and spot removers.
How is trichloroethylene removed from water?
Treatment options are available to remove trichloroethylene from well water. The most commonly used option is granular activated carbon filtration. 1 Options include central treatment (at the well or at entry to home) or a point-of-use device (kitchen sink filter).
What is the TLV for trichloroethylene?
ACGIH: The threshold limit value (TLV) is 10 ppm averaged over an 8-hour workshift and 25 ppm as a STEL (short-term exposure limit).
What is 111 trichloroethane used for?
1,1,1-Trichloroethane is a colorless, volatile, nonflammable liquid with a sweet, chloroform-like odor. It is used to make other chemicals. It has been used to clean grease from metal parts. It used to be found in many household products, such as spot cleaners and glues.
Is trichloroethylene a hazardous substance?
Trichloroethylene may cause irritation to the eyes and skin. Exposure to high concentrations can cause dizziness, headaches, sleepiness, confusion, nausea, unconsciousness, liver damage, and even death. Trichloroethylene is a known carcingen. Workers may be harmed from exposure to trichloroethylene.
What is trichloroethylene found in?
Trichloroethylene (TCE) is used as a solvent for degreasing metal parts during the manufacture of a variety of products. It can be found in consumer products, including some wood finishes, adhesives, paint removers, and stain removers.
Can ro remove trichloroethylene?
Trichloroethylene can be treated with activated carbon adsorption, reverse osmosis (removes 70 to 80 percent), and air stripping.
Is trichloroethylene a carcinogen?
The Department of Health and Human Services (DHHS) considers trichloroethylene to be a known human carcinogen. The International Agency for Research on Cancer (IARC) classified trichloroethylene as carcinogenic to humans.
What is trichloroethylene (TCE) and why is it hazardous?
– Reasonably anticipated to be a human carcinogen (EPA) – Carcinogenic to humans (IARC) – Classified as a volatile organic compound (ATSDR) – Candidate substance for toxic status (NTP)
Can TCE exposure affect your health?
Some health effects can result from fairly high TCE exposures over short periods of time—these are called acute effects. Low to moderate exposures over months or years can cause long-term, or chronic, health effects, such as immune system effects.
What are the physiological effects of trichloroethylene?
Trichloroethylene (TCE) Revised December 1997 Health Hazard Summary Trichloroethylene mainly affects the central nervous system (the brain), causing headache, nausea, dizziness, clumsiness, drowsiness, and other effects like those of being drunk. TCE can also damage the facial nerves, and it can cause skin rash. Heavy exposure can damage
Does trichloroethylene cause cancer?
Trichloroethylene (TCE) is a chemical used to make refrigerants and as a metal degreaser. It may be found in contaminated soil or water near military bases and in some commercial and household cleaning products. TCE exposure may cause kidney cancer and increase the risk of lymphoma and liver cancer.
