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 immediately.
Skin:
In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.

POISON material. If inhaled, get medical aid immediately. Remove victim to fresh air. If not breathing, give artificial respiration.
If breathing is difficult, give oxygen.
Notes to Physician:

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. Water Reactive. Material will react with water and may release a flammable and/or toxic gas. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. Runoff from fire control or dilution water may cause pollution.
Extinguishing Media:
Use carbon dioxide or dry chemical. DO NOT USE WATER! Do NOT get water inside containers.

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. Clean up spills immediately, observing precautions in the Protective Equipment section. Isolate area and deny entry. Provide ventilation. Do not expose spill to water. Evacuate unnecessary personnel. Approach spill from upwind.

Section 7 - HANDLING and STORAGE
  Handling:
Wash thoroughly after handling. Do not allow water to get into the container because of violent reaction. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Do not ingest or inhale. Store protected from light. Discard contaminated shoes. Keep from contact with moist air and steam. Use only with adequate ventilation.
Storage:
Keep from contact with oxidizing materials. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from water. Keep away from metals. Poison room locked. Do not store in metal containers. Do not store near alkaline substances. Store protected from light.

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# 10035-10-6: United Kingdom, WEL - STEL: 3 ppm STEL; 10 mg/m3 STEL United States OSHA: 3 ppm TWA; 10 mg/m3 TWA Belgium - STEL: 2 ppm VLE; 6.7 mg/m3 VLE Germany: 2 ppm TWA; 6.7 mg/m3 TWA Malaysia: 3 ppm Ceiling; 9.9 mg/m3 Ceiling Netherlands: 2 ppm STEL; 6.7 mg/m3 STEL Russia: 2 mg/m3 TWA Spain: 2 ppm VLA-EC; 7 mg/m3 VLA-EC CAS# 10294-33-4: United Kingdom, WEL - STEL: 1 ppm STEL; 10 mg/m3 STEL Belgium - TWA: 1 ppm VLE; 10 mg/m3 VLE Germany: 10 mg/m3 TWA Malaysia: 1 ppm Ceiling; 10 mg/m3 Ceiling Spain: 1 ppm VLA-EC; 10 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 prevent skin exposure.
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.
