Health Hazards Information -Recommended Personal Protective Equipment: Cartridge-type or fresh
air mask for fumes or smoke; PVC fire-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;
Symptom Following Exposure: Inhalation of mists or vapor causes immediate irritation of upper
respiratory tract. Excessive or prolonged inhalation of fumes from ignition or decomposition may cause
“metal fume fever” (sore throat, headache, fever, chills, nausea, vomiting, muscular aches,
perspiration, constricting sensation in lungs, weakness, sometimes prostration). Symptoms usually last
12-24 hrs. Eyes are immediately and severely irritated by liquid, vapor, or dilute solutions. If not
removed by thorough flushing with water, chemical may permanently damage cornea. Skin will
undergo thermal and acid burns when chemical reacts with moisture in skin. Unless washed quickly,
skin may be scarred. Treat dilute solutions with same precautions as concentrated liquid. Ingestion,
whileunlikely, would cause immediate burns at site of contact. Nausea, vomiting, cramps, and diarrhea
may follow. Tissues may ulcerate if not treated; General Trement for Exposure: INHALATION:
highly unlikely, as liquid or vapor either ignites spontaneously or reacts with moisture to form methane
and zinc oxide. Move victim to clean air and administer mouth-to-mouth resuscitation if breathing has
ceased; give oxygen only when authorized by physician; keep victim warm and comfortable; call
physician immediately. EYES: immediately flush with large amounts of water for at least 15 min.,
holding eyelids apart to insure thorough irritation; use oils or ointments only when directed by
physician, and do not attempt to neutralize with chemicals; get medical attention as soon as possible.
SKIN: immediately flush affected area with large volumes of water; do not attempt to neutralize with
chemicals; get medical attention if irritation persists. INGESTION: highly unlikely, as liquid or vapor
either ignites spontaneously or reacts with moisture to form methane and zinc oxide. Do NOT induce
vomiting; immediately dilute material by giving large amounts of water or milk; if vomiting occurs,
give more fluids; when vomiting ceases, milk or olive oil may be given for their soothing effect; get
medical attention; Toxicity by Inhalation (Threshold Limit Value): Not pertinent; ShoH-Tern Exposure
