Properties:
Greenish-yellow
gas. Amber liquid under high pressure or refrigeration. Strongly suffocating,
irritating, bleach-like odor. Soluble in water. Gas is heavier than air; will

HEALTH & SAFETY INFORMATION

• Odor threshold:
0.236 - 88.5 mg/m3
•
OSHA Table Z-1 Air Contaminant
•
OSHA Process Safety Management of Highly Hazardous Chemicals (29CFR, Part
1910.119, Appendix A): Threshold Quantity: 1,500 pounds.
• NIOSH Criteria Document
: NIOSH 76-170
•
A lacrimator. Corrosive to the eyes, skin, and respiratory tract. Inhalation of
gas may cause pneumonia and lung edema, resulting in reactive airways
dysfunction syndrome (RADS); the effects may be delayed.. Rapid evaporation of
the liquid may cause frostbite. Very high levels of exposure can cause death.
Long-term effects include impairment of breathing functions, erosion of exposed
front teeth, anxiety, and the formation of acne-like lesions on the skin.
Contact with liquid may cause frostbite. DFG pregnancy risk Group C.

Escape:

respirator (gas mask) with a chin-style, front- or back-mounted canister
providing protection against the compound of concern]
P
SCBAE (any appropriate escape-type, self-contained breathing
apparatus).
Note:
Substance reported to cause eye irritation or
damage; may require eye protection.
Reactivity:
A
powerful oxidizer. Reacts violently with combustible materials, reducing
agents, and many other substances. Forms explosive mixtures with gasoline and
petroleum products, ammonia, ether, turpentine, alcohols, acetylene, carbon
disulfide, hydrogen, anhydrous ammonia, finely divided metals, hydrocarbons,
organic compounds, and phosphorus. Fire, explosion, and the formation of toxic
fumes may result from contact with many substances including alkylphosphines,
aluminum, antimony, arsenic compounds, arsine, bismuth, boron, brass, calcium
compounds, carbon, diethyl zinc, fluorine, germanium, hydrocarbons, and rubber.
Attacks some plastics, synthetic rubber, and coatings. In the presence of
moisture, extremely corrosive to iron, steel, copper, bronze, and zinc. Aqueous
solutions of chlorine will react on long standing, especially if exposed to
light or moisture, giving off oxygen and hydrochloric acid.
FIRE INFORMATION:
Nonflammable but supports the burning of other materials. Fire
fighting gear, including SCBA, does not provide adequate protection. Vapors in
confined areas or containers may explode in fire. If exposure occurs, remove
and isolate gear immediately and thoroughly decontaminate personnel.

FIRST AID:
Move
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. Clothing frozen to the
skin should be thawed before being removed. 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. Keep victim warm and quiet.
Keep victim under observation. Effects of contact or inhalation may be delayed.
Ensure that medical personnel are aware of the material(s) involved, and take
precautions to protect themselves.
Note:
Chest radiographs should be
followed and pulmonary function tests performed.
