Health Hazards Information - Recommended Personal Protective Equipment: Cartridge-type or fresh
air mask for fumes or smoke; PVC fue-retardant or asbestos gloves; full face shield, safety glasses,
or goggles; fire-retardant coveralls as standard wear; for special cases, use asbestos coat or rain suit;
Symptoms Following Exposure: Inhalation of mist or vapor causes immediate irritation of nose and
throat; excessive or prolonged inhalation of fumes from ignition or decomposition may cause “metal
fume fever” (sore throat, headache, fever, chills, MUS=, vomitG, muscular aches, perspiration,
constricting sensation in lungs, weakness, sometimes prostration); symptoms usually last 12-24 hrs.,
with complete recovery in 24 - 48 hrs. EYES are immediately and severely irritated on contact with
liquid, vapor, or dilute solution; without thorough irrigation, cornea may be permanently damaged.
Moisture in skin combines with chemical to cause thermal and acid burns; tissue may be scarred
without prompt treatment. Ingestion is unlikely but would cause immediate burns at site of contact;
pain, nausea, vomiting, cramps, and diarrhea may follow; if untreated, tissue may be scarred without
prompt treatment. Ingestion is unlikely but would cause immediate burns at site of contact; pain,
nausea, vomiting, cramps, and diarrhea may follow; if untreated, tissue may become ulcerated; General
Tremenf for Exposure: INHALATION: move victim to fresh air and call doctor immediately; give
mouth-to-mouth resuscitation if needed; keep victim warm and comfortable; oxygen should be given
only by experienced person, and only on doctor’s instructions. EYES: flush with large amounts of
running water for at least 15 min., holding eyelids apart to insure thorough washing; get medical
attention as soon as possible; do not use chemical neutralizers, and avoid oils or ointments unless
prescribed by doctor. SKIN: flush affected area with large amounts of water; do not use chemical
neutralizers; get medical attention if irritation persists. INGESTION: do NOT induce vomiting; have
victim drink large amounts of water or milk immediately; if vomiting occurs, give more fluids; get
medical attention; Toxicity by Inhalation (Threshold Limit Value) : Not pertinent; Short-Term Exposure
Limits: Not pertinent; Toxicity by Ingestion: Not pertinent; Lute Toxicity: Not pertinent; Vapor (Gas)
Irritant Characteristics: Data not available; Liquid or Solid Initant Characteristics: Data not available;
Odor Threshold: Not pertinent.
Fire Hazards - Flash Point : Not pertinent (ignites spontaneously); Flammable Limits in Air (%): Not
pertinent; Flammable Limits in Air (%): Not pertinent; Fire Extinguishing Agents: Dry chemical, sand,
or powdered limestone; Fire Extinguishing Agents Not to be Used: Water, foam, halogenated agents,
carbon dioxide; Special Hazards of Combustion Products: Yields zinc fumes when burning; can cause
metal fume fever” (see 5.2); Behavior in Fire: Reacts spontaneously with air or oxygen, and violently
with water, evolving flammable ethane gas. Contact with water applied to adjacent fires will intensify
the fire; Ignition Temperature (deg. F): Below 0; Electrical Hazard: Not pertinent; Burning Rate: Not
pertinent.
Chemical Reactivity - Reactivity with Water :Reacts violently to form flammable ethane gas; Reactivity
with Common Materials: Will react with surface moisture< generating flammable ethane gas; Stability
During Transport: Stable; Neutralizing Agents for Acids and Cmtics: Not pertinent; Polymerization:
Not pertinent; Inhibitor of Polymerizafion: Not pertinent.
