SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

EXPOSURE
STRICT HYGIENE! AVOID EXPOSURE OF (PREGNANT) WOMEN! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION
    		• Dizziness. Headache. Sweating. Vomiting. Weakness. Fever.
    		Local exhaust or breathing protection.
    		Fresh air, rest. Refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED! Pain. Redness.
    		Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
  • EYES
    		• Pain. Redness.
    		Safety goggles, or face shield.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• (see Inhalation).
    		Do not eat, drink, or smoke during work. Wash hands before eating.
    		Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place (extra personal protection: P3 filter respirator for toxic particles).
    		Provision to contain effluent from fire extinguishing. Separated from strong oxidants, food and feedstuffs.
    		Do not transport with food and feedstuffs.
