Section 3 - HAZARDS IDENTIFICATION
  EMERGENCY OVERVIEW
Very toxic by inhalation, in contact with skin and if swallowed.
Danger of cumulative effects.Toxic.Hygroscopic (absorbs moisture from the air).Light sensitive.Moisture sensitive.
Potential Health Effects
Eye:
Contact may cause severe eye irritation and possible eye damage.
Skin:
May be absorbed through the skin. May cause severe irritation and possible burns.
Ingestion:
Harmful if swallowed. May cause kidney damage. May cause severe digestive tract irritation with abdominal pain, nausea, vomiting and diarrhea. May cause corrosion and permanent tissue destruction of the esophagus and digestive tract.
Inhalation:
May cause severe irritation of the respiratory tract with sore throat, coughing, shortness of breath and delayed lung edema. May cause effects similar to those described for ingestion.
Chronic:
Chronic inhalation and ingestion may cause effects similar to those of acute inhalation and ingestion. May cause anemia and other blood cell abnormalities. Repeated exposure may cause central nervous system damage.

Section 4 - FIRST AID MEASURES
  Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
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 immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Notes to Physician:
Antidote: The use of Dimercaprol or BAL (British Anti-Lewisite) as a chelating agent should be determined by qualified medical personnel.

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. Combustion generates toxic fumes.
Extinguishing Media:
Use foam, dry chemical, or carbon dioxide. Use agent most appropriate to extinguish fire.

Section 6 - ACCIDENTAL RELEASE MEASURES
  General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Avoid generating dusty conditions.
Provide ventilation.

Section 7 - HANDLING and STORAGE
  Handling:
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Do not ingest or inhale.
Store protected from light.
Storage:
Do not store in direct sunlight. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Poison room locked.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
  Engineering Controls:
Use adequate general or local explosion-proof ventilation to keep airborne levels to acceptable levels.
Exposure Limits CAS# 7783-35-9: United States OSHA: 0.1 mg/m3 Ceiling (listed under Mercury, ary and inorganic compounds).
Belgium - TWA: (listed as mercury, aryl and inorganic compounds): mg/m3 VLE (as Hg) France - VME: (listed as mercury, aryl and inorganic compounds): mg/m3 VME (as Hg) Germany: (listed as mercury, aryl and inorganic compounds): 0.1 m VME (as Hg) Germany: (listed as mercury inorganic compounds): Skin absorber Malaysia: (listed as mercury, aryl and inorganic compounds): 0.1 mg/m3 TWA (as Hg) Netherlands: (listed as mercury inorganic compounds): 0.15 mg/m3 Netherlands: (listed as mercury inorganic compounds): 0.05 mg/m3 Russia: (listed as mercury inorganic compounds): 0.2 mg/m3 TWA (a Hg) Russia: (listed as mercury inorganic compounds): 0.05 mg/m3 STEL Hg) Spain: (listed as mercury, aryl and inorganic compounds): 0.1 mg/ VLA-ED (as Hg) 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 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.
