Section 3 - HAZARDS IDENTIFICATION
  EMERGENCY OVERVIEW
Not available.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. May cause frostbite.
Ingestion:
Low hazard for usual industrial handling.
Inhalation:
May cause respiratory tract irritation. Vapors may cause dizziness or suffocation. Exposure to high concentrations may cause weakness, asphyxia, and death. Has poor warning properties at low concentrations. Exposure to low concentrations may cause narcotic effects. Symptoms may include headache, dizziness, nausea, and loss of coordination.
Chronic:
No information found.

Section 4 - FIRST AID MEASURES
  Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists.
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 if irritation or symptoms occur.
Inhalation:
Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
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. Containers may explode when heated. Vapors from liquefied gas are initially heavier than air and spread along ground.
Extinguishing Media:
Substance is nonflammable; use agent most appropriate to extinguish surrounding fire. Do not direct water at source of leak or safety devices; icing may occur.

Section 6 - ACCIDENTAL RELEASE MEASURES
  General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Provide ventilation. Stop leak only if you can do so without risk.
Use water spray to reduce vapors or divert vapor cloud drift.

Section 7 - HANDLING and STORAGE
  Handling:
Wash thoroughly after handling. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed.
Avoid ingestion and inhalation.
Storage:
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Store below 50C.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
  Engineering Controls:
Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.
Exposure Limits CAS# 7727-37-9: 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.
