First Aid Measures

Ingestion
If large amounts were swallowed, give water to drink and get medical advice.
Ingestion
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Wash mouth out with water. Get medical aid if irritation or symptoms occur.
Inhalation
If a person breathes in large amounts, move the exposed person to fresh air.
Inhalation
Remove from exposure to fresh air immediately. Get medical aid if cough or other symptoms appear.
Skin
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists.
Skin
In case of contact, immediately wash skin with plenty of soap and water for at least 15 minutes.
Eyes
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. If irritation develops, get medical aid.
Eyes
In case of eye contact, immediately flush with plenty of water for at least 15 minutes

Handling and Storage

Storage
Keep container tightly closed. Suitable for any general chemical storage area.
Storage
Store in a cool, dry, well-ventilated area away from incompatible substances. No special precautions indicated.
Handling
Wash hands before eating. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with skin and eyes. Avoid ingestion and inhalation. Use with adequate ventilation.

Hazards Identification

Inhalation
Low hazard for usual industrial handling.
Skin
Causes skin irritation.
Eyes
May cause eye irritation.
Ingestion
May cause irritation of the digestive tract. Low hazard for usual industrial handling.

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.
Personal Protection
Wear protective gloves and clean body-covering clothing. Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible.
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
or emergencies, or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air purifying respirators do not protect workers in oxygen-deficient atmospheres.
Exposure Effects
Reproductive effects have been reported in animals.
Poison Class

Fire Fighting Measures

Flash Point
190
Autoignition
355
Fire Fighting
Use extinguishing media appropriate for surrounding fire. Wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode.
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, or water fog.
Upper exp. limit
2.3
Lower exp. limit
.3
Fire Potential
Not expected to be a fire hazard.
Fire Potential
Slightly flammable. Fire hazard when exposed to heat or flame; it can react with oxidizing materials.

Accidental Release Measures

Small spills/leaks
Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Avoid generating dusty conditions.
