Health Hazards Information -Recommended Personal Protective Equipment: Respirator for dust or
mist protection; rubber, neoprene, or vinyl gloves; chemical safety glasses; rubbers, over leather or
rubber safety shoes; apron or impervious clothmg for splash protection; Symptoms Following Exposure:
As dust or as a solution, can cause severe burns of eyes, skin, or mucous membranes. Ingestion of 5
grams has caused death with symptoms of nausea, shock, collapse, and convulsions coming on rapidly.
Repeated or prolonged skin exposure can cause dermatitis and slow-healing ulcers; General Treatment
for Exposure: Get medical attention for all eye exposure and any serious overexposures; treat men^ is
symptomatic. INHALATION: rinse mouth ador gargle repeatedly with cold water. INGESTION
dilute by drinking large amounts of water; repeat at least once and then administer milk or milk of
magnesia as an emollient; do NOT induce vomiting. EYES and SKIN: flush thoroughly with water;
Toxicity by Inhalation (Threshold Limit Value): Not pertinent; Short-Ten Inhalation Limits: Not
pertinent; Toxicity by Ingestion: Grade 3, LD,, 50 to 500 mg/kg; Late Toxicity: Data not available;
Vapor (Gas) Im’tant characteristics: Data not available; Liquid or Solid Initant characteristics: Severe
skin irritant. Causes second- and third-degree burns on short contact and is very injurious to the eyes;
Odor Threshold Not pertinent.
Fire Hazards - Flash Point : Not flammable; Flammable Limits in Air (%): Not flammable; Fire
Extinguishing Agents: Not pertinent; Fire Extinguishing Agents Not to be Used: Not pertinent; Special
Hazards of Combustion Products: Generates poisonous gases; Behavior in Fire: Not pertinent; Ignition
Temperature : Not flammable; Electrical Hazard Not pertinent; Burning Rate: Not flammable.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materiab: No
reaction; Stability During Transport: Stable; Neuralking Agents for Acids and Caustics: Lime or soda
ash; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

OXYGEN, LIQUEFIED

Vaporization: 91.6, 50.9, 2.13; Heat of Combustion: Not pertinent; Heat ofDecomposition: Not
pertinent.
Health Hazards Information - Recommended Personal Protective Equipment: Safety goggles or face
shield; insulated gloves; long sleeves; trousers worn outside boots or over high-top shoes to shed spilled
liquid; Symptoms Following Exposure: Inhalation of 100% oxygen can cause MUSM, dizziness,
irritation of lungs, pulmo~ry edema, pneumonia, and collapse. Liquid may cause frostbite of eyes and
skin; General Treatment for Exposure: INHALATION: in all but the most severe cases (pneumonia),
recovery is rapid ah reduction of oxygen pressure; supportive treatment should include immediate
sedation, anticonvulsive therapy if needed, and rest. EYES: treat frostbite burns. SKIN: treat frostbite;
soak in lukewarm water; Toxicity by Inhalation (Threshold Limit Value): Not pertinent; Short-Ten
Inhalation Limits: Not pertinent; Toxicity by Ingestion: Not pertinent; Lute Toxicity: Not pertinent;
Vapor (Gar) Im‘tant Characteristics: Data not available; Liquid or Solid Im‘tant characteristics: Data
