TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Combustible.	NO open flames.	Water spray, powder, AFFF, 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. Prevent build-up of electrostatic charges (e.g., by grounding).

EXPOSURE		PREVENT DISPERSION OF DUST!
INHALATION	Cough. Nausea. Vomiting.	Avoid inhalation of fine dust and mist. Local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
SKIN		Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
EYES	Redness. Pain.	Safety goggles, or eye protection in combination with breathing protection if powder.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
INGESTION	(further see Inhalation).	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. 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: A/P2 filter respirator for organic vapour and harmful dust).

Separated from food and feedstuffs and oxidants.

Do not transport with food and feedstuffs.

ENVIRONMENTAL
DATA

This substance may be hazardous to the environment; special attention should be given to water. In the food chain important to humans, bioaccumulation takes place, specifically in plants. It is strongly advised not to let the chemical enter into the environment because it persists in the environment.

N O T E S

Do NOT take working clothes home. Dowtherm A is a trade name.
