TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Not combustible but enhances combustion of other substances. 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	Cough. Sore throat. Burning sensation. 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! Redness. Pain. Skin burns. Blisters.	Protective gloves. Protective clothing.	First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.
Eyes	Redness. Pain. Blurred vision. 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	Burning sensation. Abdominal pain. Diarrhoea. Nausea. Vomiting. Metallic taste.	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Sweep spilled substance into containers. Carefully collect remainder, then remove to safe place. Do NOT absorb in saw-dust or other combustible absorbents. Do NOT let this chemical enter the environment. (Extra personal protection: complete protective clothing including self-contained breathing apparatus).	T+ Symbol N Symbol R: 26/27/28-33-50/53 S: (1/2-)13-28-45-60-61 Note: A UN Hazard Class: 6.1 UN Pack Group: II	Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs. Severe marine pollutant.

EMERGENCY RESPONSE	STORAGE
Transport Emergency Card: TEC (R)-61G64b	Separated from combustible and reducing substances, food and feedstuffs. Keep in the dark.

IMPORTANT DATA

Physical State; Appearance
COLOURLESS CRYSTALS OR WHITE, HYGROSCOPIC POWDER.

Chemical dangers
Shock-sensitive compounds are formed with phosphinic acid, ethanol and acetylene. The substance is a strong oxidant and reacts violently with combustible and reducing materials. The substance decomposes under influence of light.

Occupational exposure limits
TLV (as Hg): 0.025 mg/m³ (skin) A4 (ACGIH 1999).
MAK as Hg: 0.1 mg/m³; BAT 25 µg/l in blood; 100 µg/l in urine (1999)
MAK as Hg STEL: 1 mg/m³; (1999)
MAK: class Sh (1999)

Routes of exposure
The substance can be absorbed into the body by inhalation, 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, kidneys and peripheral nervous system, resulting in ataxia, sensory and memory disturbances, fatigue, muscle weakness and kidney impairment.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Melting point: 79°C Density: 4.4 g/cm³ Solubility in water: good	The substance is very toxic to aquatic organisms. In the food chain important to humans, bioaccumulation takes place, specifically in aquatic organisms. It is strongly advised not to let the chemical enter into the environment because it persists in the environment.

NOTES

Depending on the degree of exposure, periodic medical examination is indicated.
Do NOT take working clothes home.
