ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking.
Water in large amounts.
EXPLOSION

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE


•INHALATION
Ventilation.
Fresh air, rest.
•SKIN
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
•EYES Redness.

DATA


N O T E S

The commercial products are formulated with 30-35% of water, or ethanol, or 1-butanol or Isopropanol. Carrier solvents used in commercial formulations may change physical and toxicological properties. If the substance is formulated with solvents also consult the ICSCs of these materials. The formulation with more than 12.6% nitrogen is used exclusively for the explosives; EU classification: Index number 603-037-00-6, symbol E, R:1-3, S:(2-)35.
