SECTION 3 - HAZARDS IDENTIFICATION EMERGENCY OVERVIEW Harmful if swallowed. Irritating to skin. Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. Contact with the skin defats the skin. A single prolonged skin exposure is not likely to result in the material being absorbed in harmful amounts.
Ingestion:
Harmful if swallowed.
Inhalation:
Causes respiratory tract irritation. May cause liver damage.
Chronic:
Chronic exposure may cause liver damage.
SECTION 4 - FIRST AID MEASURES
Eyes:
In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical aid.
Skin:
In case of contact, flush skin with plenty of water. Remove contaminated clothing and shoes. Get medical aid if irritation develops and persists. Wash clothing before reuse.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Get medical aid.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
SECTION 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, 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. Use water spray to keep fire-exposed containers cool. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or appropriate foam.
SECTION 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, observing precautions in the Protective Equipment section. Provide ventilation.
SECTION 7 - HANDLING and STORAGE
Handling:
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Avoid breathing vapor or mist.
Storage:
Store in a cool, dry place. Store in a tightly closed container.
SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other engineering controls to control airborne levels below recommended exposure limits. Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Exposure Limits CAS# 120-82-1: United Kingdom, WEL - TWA: 1 ppm TWA United Kingdom, WEL - STEL: 5 ppm STEL Belgium - TWA: 2 ppm VLE; 15.1 mg/m3 VLE Belgium - STEL: 5 ppm VLE; 37.8 mg/m3 VLE France - VME: 5 ppm VME; 40 mg/m3 VME

Spain: 2 ppm VLA-ED; 15 mg/m3 VLA-ED
Spain: 5 ppm VLA-EC; 38 mg/m3 VLA-EC Personal Protective Equipment
Eyes:
Wear chemical splash goggles.
Skin:
Wear appropriate protective gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to minimize contact with skin.
Respirators:
Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
