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
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
