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
Get medical aid. Wash mouth out with water.
Inhalation
May cause respiratory tract irritation. May be harmful if inhaled. May cause salicylism with effects similar skin absorption.
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 breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
Inhalation
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Skin
May cause skin irritation. May be harmful if absorbed through the skin. Absorption through the skin may cause salicylism, characterized by deep and rapid breathing, nausea, vomiting, tinnitis, gastrointestinal irritation with possible ulcers and possible strokes.
Skin
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
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.
Eyes
May cause eye irritation.
Eyes
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Eyes
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.

Handling and Storage

Storage
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Do not store in direct sunlight. Keep container closed when not in use. Store in a tightly closed container. Keep from contact with oxidizing materials. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from strong bases. Material darkens in color on storage.
Storage
Store in a tightly closed container. Deep freeze (below -20 C).
Handling
Wash thoroughly after handling. Minimize dust generation and accumulation. Do not get on skin and clothing. Do not ingest or inhale. Store protected from light. Use only in a chemical fume hood. Do not breathe dust or fumes.
Handling
Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin and eyes.

Hazards Identification

Ingestion
May cause irritation of the digestive tract. May be harmful if swallowed. May cause salicylism with effects similar to skin
Inhalation
May be fatal if inhaled. Causes respiratory tract irritation.
Skin
Causes mild skin irritation.
Eyes
Causes moderate eye irritation. May cause lens opacities and retinal changes.
Ingestion
Aspiration hazard. May cause irritation of the digestive tract. May be harmful if swallowed.
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 prevent skin exposure.
Personal Protection
Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
Respirators
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
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
Chronic inhalation may cause effects similar to those of acute inhalation. Laboratory experiments have resulted in mutagenic effects. Prolonged exposure may cause abdominal pain, nausea, vomiting, and possible convulsions. Intestinal and percutaneous absorption may lead to severe nephritis, liver injury and acute hemolytic anemia.

Autoignition
550
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. Extinguishing media: Use extinguishing media most appropriate for the surrounding fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.

Fire Potential
Slightly flammable. Requires preheating.

Accidental Release Measures

Small spills/leaks
Vacuum or sweep up material and place into a suitable disposal container.
