Section 3 - Hazards Identification

EMERGENCY OVERVIEW

Appearance: red powder.
Danger! Very toxic by inhalation, in contact with skin and if swallowed. May be fatal if inhaled, absorbed through the skin or swallowed. May cause eye, skin, and respiratory tract irritation. May cause central nervous system effects. Danger of cumulative effects.
Target Organs: Kidneys, central nervous system.


Potential Health Effects
Eye: May cause eye irritation.
Skin: May cause skin irritation. May be fatal if absorbed through the skin.
Ingestion: May be fatal if swallowed. May cause irritation of the digestive tract. May cause central nervous system effects.
Inhalation: May be fatal if inhaled. May cause respiratory tract irritation.
Chronic: May cause kidney injury. Chronic exposure to mercury may cause permanent central nervous system damage, fatigue, weight loss, tremors, personality changes.

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 imme diately.
Skin: Get medical aid immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion: Do not induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid immediately.
Inhalation: Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Get medical aid. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
Notes to Physician: Treat symptomatically and supportively.
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
