Section 3: Hazards Identification
   Mercury salts are poisonous by ingestion and inhalation of dust. Acute effects include kidney failure.
   Emergency Overview:
   Prolonged exposure may cause heritable genetic damage and impaired fertility.
   Primary Routes of Exposure:       Ingestion, skin, Inhalation of dust.    
   Eye Contact:       May cause mild to severe irritation of the eyes. May deposit mercury in the lens of the eye.    
   Skin Contact:       May cause mild to severe irritation of the skin. Toxic in contact with skin.    
   Toxic by inhalation. Dust may cause severe respiratory and gastrointestinal distress, and may damage the
   central nervous system.
   Very toxic if swallowed. Lack of appetite, abdominal cramps, vomiting, kidney failure, paralysis. Mercury binds
   to thiol groups of protein.
   Poison. Stomach upset and pain, mouth pain, vomiting, excessive salivation, urine production stops, urine
   Acute Health Affects:
   products appear in the blood, ataxia (difficulty in moving).
   The chronic effects of mercury poisoning include stomatitis, tremors, psychic disturbances, excessive
   Chronic Health Affects:
   salivation, dermatitis, and pain on chewing. May cause heritable genetic damage and impair fertility.
   NTP:       No    
   IARC:       No    
   OSHA:       No    

SECTION 4: First Aid Measures
   Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need
   Eye Exposure:
   assistance in keeping their eye lids open. Get immediate medical attention.
   Wash the affected area with water. Remove contaminated clothes if necessary. Apply calcium gluconate jelly
   Skin Exposure:
   or water soluble calcium salts as antidote. Seek medical assistance.
   Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty
   in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance.
   Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce
   vomiting only if directed by medical personnel.

SECTION 8: Exposure Controls and Personal Protection
   Eye Protection:       Always wear approved safety glasses when handling a chemical substance in the laboratory.    
   Skin Protection:       Wear protective clothing and gloves. Consult with glove manufacturer to determine the proper type of glove.    
   Ventilation:       solid may form a toxic fine dust. If possible, handle the solid in an efficient fume hood.    
   If in form of fine dust and ventilation is not available a respirator should be worn. The use of respirators
   requires a Respirator Protection Program to be in compliance with 29 CFR 1910.134.
   Ventilation:       solid may form a toxic fine dust. If possible, handle the solid in an efficient fume hood.    
   Additional Protection:       No additional protection required.
