First Aid Measures

Ingestion
Do NOT induce vomiting. Never give anything by mouth to an unconscious person.

Inhalation
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 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
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.

Eyes
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Do NOT allow victim to rub or keep eyes closed.

Handling and Storage

Storage
No special storage requirements.

Handling
Wash thoroughly after handling.

Hazards Identification

Inhalation
May cause burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. Inhalation of dust causes severe irritation of the nose and throat. Vapors are extremely irritating to the respiratory tract.

Skin
Harmful if absorbed through the skin.

Eyes
Lachrymator. Contact may cause irritation, tearing, and burning pain.

Ingestion
Poison by ingestion.

Hazards
Containers may explode when heated. Runoff may pollute waterways.

Exposure Controls/Personal Protection

Personal Protection
Eyes: Wear safety glasses and chemical goggles if splashing is possible. Skin: Wear appropriate protective gloves and clothing to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin.

Respirators
Wear a NIOSH/MSHA or European Standard EN 149 approved full-facepiece airline respirator in the positive pressure mode with emergency escape provisions.

Exposure Effects
Chronic exposure may cause liver damage.

Exposure limit(s)
TLV: 0.1 ppm; 1.4 mg/m3 (as TWA); 0.3 ppm; 4.1 mg/m3 (as STEL) (ACGIH 1991-1992). NIOSH REL: TWA 0.1 ppm (1.4 mg/m3) ST 0.3 ppm (4 mg/m3)

Fire Fighting Measures

Flash Point
65

Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Water runoff can cause environmental damage. Dike and collect water used to fight fire. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. To extinguish fire, use water fog, dry chemical, carbon dioxide, or regular foam.

Fire Potential
Not flammable by standard tests in air
