First Aid Measures

Ingestion

Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.

Ingestion

Harmful if swallowed. Causes severe digestive tract burns with abdominal pain, vomiting, and possible death. May cause corrosion and permanent tissue destruction of the esophagus and digestive tract. In the Pancreas, may cause elevated glucose and amylase levels while depressing the calcium level.

Inhalation

May cause cyanosis, characterized by bluish-colored skin. May cause severe irritation of the respiratory tract with sore throat, coughing, shortness of breath and delayed lung edema. Inhalation of fumes may cause metal fume fever, which is characterized by flu-like symptoms with metallic taste, fever, chills, cough, weakness, chest pain, muscle pain and increased white blood cell count.

Inhalation

Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. DO NOT use mouth-to-mouth respiration.

Skin

Contact with skin causes irritation and possible burns, especially if the skin is wet or moist.

Skin

Get medical aid immediately. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes.

Eyes

May cause irreversible eye injury. Contact with eyes may cause severe irritation, and possible eye burns.

Eyes

Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed.

Handling and Storage

Storage

Store in a cool, dry place. Keep away from water. Corrosives area. Do not store in metal containers. Keep containers tightly closed.

Handling

Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Do not get in eyes, on skin, or on clothing. Do not ingest or inhale. Discard contaminated shoes.

Hazards

Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.

Exposure Controls/Personal Protection

Personal Protection

Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure. Wear an impervious apron.

Respirators

A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.

Exposure Effects

Prolonged or repeated skin contact may cause defatting and dermatitis. May cause reproductive and fetal effects.

Exposure limit(s)

NIOSH REL: TWA 1 mg/m3 ST 2 mg/m3 OSHA PEL: TWA 1 mg/m3 IDLH 50 mg/m3

Fire Fighting Measures

Fire Fighting

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Substance is noncombustible. Containers may explode in the heat of a fire. Contact with metals may evolve flammable hydrogen gas. Extinguishing media: Use extinguishing media most appropriate for the surrounding fire. Do NOT get water inside containers. For small fires, use dry chemical, carbon dioxide, or water spray. For large fires, use dry chemical, carbon dioxide, alcohol-resistant foam, or water spray. Cool containers with flooding quantities of water until well after fire is out.

Fire Potential

Nonflammable. Combustion with moderate heating.

Accidental Release Measures

Small spills/leaks

Avoid runoff into storm sewers and ditches which lead to waterways. Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Avoid generating dusty conditions. Remove all sources of ignition. Do not get water inside containers.

Stability and Reactivity

Stability

Stable under normal temperatures and pressures.

Incompatibilities

Strong oxidizing agents, moisture, cyanides, sulfides, potassium.

Decomposition

Hydrogen chloride, chlorine, irritating and toxic fumes and gases, toxic fumes of zinc oxide.

Combustion Products

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
