POLYVINYL ALCOHOL	ICSC: 1489 (October 2004)
Ethenol, homopolymer

CAS #: 9002-89-5

	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Finely dispersed particles form explosive mixtures in air.	NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust. Prevent build-up of electrostatic charges (e.g., by grounding).	Use water spray, powder, alcohol-resistant foam, carbon dioxide.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough.	Avoid inhalation of dust.	Fresh air, rest.
Skin		Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Redness.	Wear safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion		Do not eat, drink, or smoke during work.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered suitable containers. Do NOT let this chemical enter the environment.	According to UN GHS Criteria Transportation UN Classification
STORAGE
Separated from strong oxidants and strong acids.

POLYVINYL ALCOHOL

ICSC: 1489

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS-TO-WHITE SOLID IN VARIOUS FORMS. Physical dangers Dust explosion possible if in powder or granular form, mixed with air. As a result of flow, agitation, etc., electrostatic charges can be generated. Chemical dangers Decomposes on heating and on burning. This produces toxic fumes. Reacts with oxidants and strong acids.	Formula: (CH₂CHOH-)n Molecular mass: variable (polymer) Decomposes at >200°C Density: 1.19-1.31 g/cm³ Solubility in water: good Flash point: 79°C o.c.
