First Aid Measures

Ingestion

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

Inhalation

Get medical aid immediately. Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. Do not use mouth-to-mouth respiration if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device.

Skin

Get medical aid immediately. 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

Immediately 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. Extensive irrigation is required (at least 30 minutes).

Handling and Storage

Storage

Keep container closed when not in use. Corrosives area. Store protected from moisture. Store in a cool, dry area away from incompatible substances.

Handling

Keep container tightly closed. Do not get on skin or in eyes. Do not ingest or inhale. Use with adequate ventilation. Use only in a chemical fume hood. Discard contaminated shoes. Keep from contact with moist air and steam.

Hazards Identification

Inhalation

Causes chemical burns to the respiratory tract. Inhalation may be fatal as a result of spasm, inflammation, edema of the larynx and bronchi, chemical pneumonitis and pulmonary edema. May cause systemic effects. Inhalation may produce burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting.

Skin

Causes skin burns. May cause skin rash (in milder cases), and cold and clammy skin with cyanosis or pale color.

Eyes

Causes eye burns. May cause chemical conjunctivitis and corneal damage.

Ingestion

May cause severe and permanent damage to the digestive tract. Causes gastrointestinal tract burns. May cause perforation of the digestive tract. May cause systemic effects.

Hazards

Contact with metals may evolve flammable hydrogen gas.

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 minimize contact with skin.

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

Effects may be delayed.

Fire Fighting Measures

Flash Point

18

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. To extinguish fire, use carbon dioxide, dry chemical powder or appropriate foam.

Fire Potential

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

Accidental Release Measures

Small spills/leaks

Clean up spills immediately, using the appropriate protective equipment. Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Provide ventilation.

Stability and Reactivity

Disposal Code

4

Stability

Stable under normal temperatures and pressures. Moisture sensitive.

Incompatibilities

Strong oxidizing agents, strong acids, strong bases, moisture, water.

Decomposition

Carbon monoxide, carbon dioxide, hydrogen fluoride.

Combustion Products

Fire may produce irritating, corrosive and/or toxic gases.
