Health Hazards Information - Recommended Personal Protective Equipment: Quick-opening safety
shower and eye fountain; respiratory equipment approved fro chlorine service. Wear safety goggles at
all times when in vicinity of liquid chlorine; Symptoms Following Exposure: Eye irritation, sneezing,
copious salvation, general excitement and restlessness. Irritation may persists for several days. High
concentrations cause respiratory distress and violent coughing, often with retching. Death may result
from suffocation; General Treatment for Exposure: INHALATION: remove victim from source of
exposure; call a doctor; support respiration; administer oxygen. EYES: flush with copious amounts of
water for at least 15 min.; Toxicity by Inhalation (ThresholdLimit Value): 1 ppm; Short-Tern Exposure
Limits: 3 ppm for 5 min.; Toxicity by Ingestion: Not pertinent; ingestion unlikely (chlorine is gas above
-34.5"C); Lute Toxicity: None; Vapor (Gas) Irritant Characteristics: Vapors cause severe irritation of
eyes and throat and can cause eye and lung injury. They cannot be tolerated even at low concentrations;
Liquid or Solid Irritant Characteristics: Causes smarting of the skin and first-degree burns on short
exposure; may cause secondary burns on long exposure; Odor Threshold 3.5 ppm.
Fire Hazards - Flash Point: Not flammable; Flamble Limits in Air (%): Not flammable; Fire
Extinguishing .Agents: Not pertinent; Fire Extinguishing Agents Not To Be Used Not pertinent; Special
Hazards of Combustion Products: Toxic products are generated when combustibles burn in the presence
of chlorine; Behavior in Fire: Most combustible materials will burn in the presence of chlorine even
though chlorine itself is not flammable; Ignition Temperature: Not flammable; Electrical Hazard No
data; Burning Rare: Not flammable.
Chemical Reactivity - Reactivity with Water: Forms a corrosive solution; Reactivity with Common
Materials: Reacts vigorously with most metals especially at high temperatures. Copper may burn
spontaneously; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not
pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
