colorless, watery liquid. Sweet ether-like odor. Sinks in water; slightly
soluble. Toxic and irritating gases of phosgene and hydrogen chloride are
produced when heated. Vapors are heavier than air; will collect in low areas.
HEALTH & SAFETY INFORMATION
ppm. Potential human carcinogen.
2B, possible human carcinogen; human evidence, limited; animal evidence,
Clear evidence, carcinogenesis (mouse, rat).
• Odor threshold:
OSHA Table Z-1 Air Contaminant
• NIOSH Criteria Document
: NIOSH 75-114
Causes irritation of the eyes, skin, and respiratory tract. May affect the
central nervous system, liver, and kidneys. The effects may be delayed.
Long-term exposure may include sluggishness, depression, hallucinations, loss
of appetite, fatigue, and liver and kidney damage. Chloroform is a suspected
carcinogenic agent because high levels cause kidney, liver, and thyroid cancer
in rats and mice. Abnormal sperm found in laboratory tests.
ACGIH TLV: 10 ppm TWA; confirmed animal carcinogen with unknown relevance to
OSHA PEL: 50 ppm/240 mg/m3 ceiling limit
NIOSH REL: 2 ppm/9.78 mg/m3 60 min. STEL. Reduce exposure to lowest feasible

in the presence of excess water, sunlight, or high temperatures, forms highly
toxic and corrosive phosgene and hydrogen chloride. Strong alkalies like lye
and potassium hydroxide decompose chloroform to chloride salts and formates.
Can become explosive in the presence of strong alkalies and water. In contact
with water and high temperatures, becomes corrosive; attacks iron and other
metals. Incompatible with acetone, aluminum, Strong oxidizers, potassium,
sodium, chemically active metals, and strong bases. Attacks plastics and
rubber. Can accumulate static electrical charges.
If material or contaminated runoff enters waterways, notify
downstream users of potentially contaminated water.

victim to fresh air. Call emergency medical care. Apply artificial respiration
if victim is not breathing. Do not use mouth-to-mouth method if victim ingested
or inhaled the substance; induce artificial respiration with the aid of a
pocket mask equipped with a one-way valve or other proper respiratory medical
device. Administer oxygen if breathing is difficult. Remove and isolate
contaminated clothing and shoes. In case of contact with substance, immediately
flush skin or eyes with running water for at least 20 minutes. For minor skin
contact, avoid spreading material on unaffected skin. Keep victim warm and
quiet. Effects of exposure (inhalation, ingestion, or skin contact) may be
delayed. Ensure that medical personnel are aware of the material(s) involved,
and take precautions to protect themselves.
