Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: all extinguishing agents allowed. EXPLOSION EXPOSURE AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!  •INHALATION Sore throat. Cough. Headache. Laboured breathing. Shortness of breath. Local exhaust or breathing protection. Fresh air, rest. Half-upright position. Refer for medical attention.  •SKIN MAY BE ABSORBED! Skin burns. Pain. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.  •EYES Redness. Pain. Severe deep burns. Face shield, or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Abdominal pain. Burning sensation. Diarrhoea. Vomiting. Metallic taste. Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

International Chemical Safety Cards MERCURIC ACETATE ICSC: 0978 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE CRYSTALS, OR WHITE CRYSTALLINE POWDER. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating and under influence of light. Attacks many metals . OCCUPATIONAL EXPOSURE LIMITS: TLV (as Hg): 0.025 mg/m3 (skin) A4 (ACGIH 1999). MAK as Hg: 0.01 mg/m3; BAT 25 mg/l in blood, 100 ug/l in urine (1999) MAK as Hg STEL: 1 mg/m^3; (1999) MAK: class Sh (1999) ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. The substance may cause effects on the kidneys . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the central nervous system peripheral nervous system and kidneys , resulting in ataxia, sensory and memory disturbances, tremors, muscle weakness and kidney impairment. PHYSICAL PROPERTIES Melting point (decomposes): 178°C Density: 3.28 g/cm3 Solubility in water, g/100 ml at 20°C: 40 ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. In the food chain important to humans, bioaccumulation takes place, specifically in aquatic organism. It is strongly advised not to let the chemical enter into the environment because it persists in the environment. N O T E S Depending on the degree of exposure, periodic medical examination is indicated. Do NOT take working clothes home.
