Section 3 - HAZARDS IDENTIFICATION
  EMERGENCY OVERVIEW
Explosive when dry. Highly flammable. Harmful if swallowed. Limited evidence of a carcinogenic effect.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
No information regarding skin irritation and other potential effects was found.
Ingestion:
The toxicological properties of this substance have not been fully investigated. May be harmful if swallowed.
Inhalation:
The toxicological properties of this substance have not been fully investigated. Inhalation of dust may cause respiratory tract irritation.
Chronic:
No information found.

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. Flammable solid. May be ignited by friction, heat, sparks, or flame. May decompose explosively when heated or involved in a fire. Severe explosion and fire risk if not kept moist.
Extinguishing Media:
Cool containers with flooding quantities of water until well after fire is out. 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:
Vacuum or sweep up material and place into a suitable disposal container. Avoid generating dusty conditions. Remove all sources of ignition. If the material is dry, explosives experts may be necessary to dispose of the spill. Wet area to prevent drying out. Provide ventilation. Use only non-sparking tools and equipment.

Section 7 - HANDLING and STORAGE
  Handling:
Wash thoroughly after handling. Minimize dust generation and accumulation. Ground and bond containers when transferring material.
Use spark-proof tools and explosion proof equipment. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Do not use if the material has evaporated to dryness. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Use only with adequate ventilation.
Keep away from heat, sparks and flame. Avoid breathing dust. Do not allow to dry on clothing. Drying on clothing or other combustible materials may cause fire. Keep wet with water.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Material can ignite if dry. Do not allow material to completely dry. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep moist. Keep wet with water.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
  Engineering Controls:
Use explosion-proof ventilation equipment. Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate ventilation to keep airborne concentrations low.
Exposure Limits CAS# 119-26-6: CAS# 7732-18-5: Personal Protective Equipment 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 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.
