HYDROGEN PEROXIDE 207

Health Hazards Information - Recommended Personal Protective Eppment: Safety goggles or face
shield; insulated gloves and long sleeves; cuffless trousers worn outside boots or over high-top shoes
to shed spilled liquid; self-contained breathing apparatus containing air (never use oxygen); !Tymptoms
Following Exposure: If atmosphere does not contain enough oxygen, inhalation can cause dizziness,
unconsciousness, or even death. Contact of liquid with eyes or skin causes freezing similar to a bum;
General Treatment for Exposure: The only effect of exposure to liquid hydrogen is that caused by its
unusually low temperature and its action as a simple asphyxiate. INHALATION. if victim is
unconscious (due to oxygen deficiency), move him to fresh air and apply resuscitation method; call
physician. EYES: treat for frostbite. SRIN: treat for frostbite; soak in lukewarm water; get medical
attention if burn is severe; Toxicity by Inhalation (Threshold Limit Vahe): Gas is non-poisonous but
can act as a simple asphyxiate; Short-Term Inhalation Limits: Not pertinent; Tmicity by Ingestion: Not
pertinent (gas with low boiling point); Lute Toxicity: None; Vapor (Gas) Irritant characteristics: Data
not available; Liquid or Solid Irritant Characteristics: Data not available; Odor i%reshold Not
pertinent.
F'ire Hazards - F&sh Point : Not pertinent; Fhumble Limits in Air (%): 4.0 - 75.0; Fire
Extinguishing Agents: Let fire burn; shut off gas supply; Fire Extinguishing Agents Not To Be Used:
Carbon dioxide; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire: Burns with
an almost invisible flame; Ignition Temperature (deg. F): 1,065; Electrical Hazard: Class I, Group B;
Burning Rate: 9.9 dmin.
Chemical Reactivity - Reactiviry with Waer: Ambient temperature of water will cause vigorous
vaporization of hydrogen; Reactivity with Common Materials: No chemical reaction, but low
temperature causes most materials to become very brittle; Stability During Transport: Stable;
Neutralizing Agentsfor Acih and Caustics: Not pertinent; Polyme&ation: Not pertinent; Inhibitor of
Polymerization: Not pertinent.

Chemical Designations - anonyms: Peroxide, Albone, Superoxol; Chemical Formula: H,O,-&O.
Observable Characteristics - Physical Stare (as shipped): Liquid; Color: Colorless; Odor: Slightly
sharp.
Physical and Chemical Properties - Physical .State at 15 "c and I am. : Liquid; Molecular Weight:
34.01; Boiling Point at I am.: 257, 125, 398; Freezing Point: -40.5, -40.3, 232.9; Critical

Health Hazards Information - Recmerukd Personal Protective Equipment: Protective garments,
both outer and inner, made of a woven polyester fabric or of modacrylic or polyvinylidene fabrics;
impermeable apron made of polyvinyl chloride or polyethylene film; neoprene gloves and boots;
goggles; Symptoms Following Exposure: Although solutions and vapors are nontoxic, they are irritating.
Vapor causes discomfort of eyes and nose. Moderately co-ted liquid causes whitening of the skin
and severe stinging sensation. In most causes the stinging subsides quickly and the skin gradually
returns to normal without any damage. Highly concentrated liquid can cause blistering of skin if left
on for any length of time; can also cause eye damage; General Treatment for Exposure: Contact should
be avoided, but immediate flushing with water will prevent any reaction in case of accidental contact;
TQxicity by Inhalation (Ebeshold Limit Value)): 1 ppm; short-Tern Inhalation Limits: Data not
available; Toxicity by Ingestion: Data not available; Lare Toxicity: None; Vapor (Gas) Im-tant
Characteristics: Vapors cause moderate irritation, such that personnel will find high concentrations
unpleasant. The effect is temporary; Liquid or Solid Irritant Characteristics: Fairly severe skin irritant.
May cause pain and second-degree burns after a few minutes' contact; Odor Threshold: Not pertinent.
Ere Hazards - FZash Point: Not flammable but may cause fire and violent reactions on contact with
combustibles and metals; Flammable Limits in Air (%): Not flammable; Fire Extinguishing Agents:
Water for fires resulting from spillage; Fire Extinguishing Agents Not To Be Used: Not pertinent;
