5. HEALTH HAZARD DATA Routes of Entry Inhalation, Ingestion, Eyes Effects of Exposure/Symptoms Causes irritation of eyes and mucous membrane. Absorption via inhalation or ingestion causes urination or acid urine. Large amount causes systematic acidosis and methemoglobinemia. Emergency Treatment Remove the victim from the exposure - Symptoms are reversible. Seek medical aid. Odour Threshold Odourless NFPA Hazard Signals Health 2 Flammability 0 Reactivity 3 Special Oxy
6. PREVENTIVE MEASURES Personal Avoid contact with solid or dust Protective Provide full personal protective equipment such as hand gloves, face shield, self-contained breathing apparatus. Equipment Body overclothing and shoes. Handling and Storage precautions A relatively stable explosive, which has however caused many industrial explosions. It is important that the mass of the materials be kept cool. Well ventilated. Prevent contact with combustible substances and reducing materials.
7. EMERGENCY/FIRST AID MEASURES FIRE Fire Extinguishing Media Use large quantity of water in early stages of fire.
EXPOSURE First Aid Measures Remove victim from the exposed area to fresh air- symptoms are reversible. Seek medical aid Antidotes/Dosages Not Available
SPILLS Steps To Be Taken Transfer spillage into large container of water. Add soda ash and neutralise with HCL. After few hours can be drained with large amount of water. Waste Disposal Method Slowly collect the material and seal in vapour tight plastic bags for eventual disposal
8. ADDITIONAL INFORMATION/REFERENCES A powerful oxidiser. A relatively stable explosive which has however caused industrial explosions. Forms heat or shock sensitive.
