First Aid Measures

Ingestion
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.
Inhalation
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
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.
Eyes
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids.

Handling and Storage

Storage
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 acids. Keep away from strong bases.
Handling
Use with adequate ventilation. Avoid contact with skin and eyes. Avoid ingestion and inhalation.

Hazards Identification

Ingestion
Ingestion of large amounts may cause gastrointestinal irritation.
Inhalation
Causes respiratory tract irritation.
Skin
Exposure may cause irritation and possible burns.
Eyes
Contact with eyes may cause severe irritation, and possible eye burns.
Hazards
Vapors are heavier than air and may travel along the ground or be moved by ventilation and ignited by heat, pilot lights, other flames and ignition sources at locations distant from material handling point. Never use welding or cutting torch on or near drum (even empty) because product (even just residue) can ignite explosively.

Exposure Controls/Personal Protection

Personal Protection
Eyes: Wear chemical goggles and a face shield. Skin: Wear appropriate gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
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. A NIOSH/MSHA approved air purifying dust or mist respirator or European Standard EN 149.
Poison Class
4

Fire Fighting Measures

Fire Fighting
Extinguish fire using regular foam, carbon dioxide, dry chemical. Wear a self-contained breathing apparatus with a full facepiece operated in the positive pressure demand mode with appropriate turn-out gear and chemical resistant personal protective equipment. Refer to the personal protective equipment section of this MSDS.
