TYPES OF HAZARD
/ EXPOSURE
ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE-FIGHTING
FIRE Combustible.  NO open flames.  Use water spray, powder, alcohol-resistant foam, carbon dioxide. 
EXPLOSION Above 71°C explosive vapour/air mixtures may be formed. Finely dispersed particles form explosive mixtures in air.  Above 71°C use a closed system and ventilation. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust. Prevent build-up of electrostatic charges (e.g., by grounding).   
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Cough. Sore throat. Burning sensation. Laboured breathing.  Use local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer for medical attention. 
Skin Redness. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain. Burns.  Wear 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 refer for medical attention. 
Ingestion Burning sensation in the throat and chest.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention if you fell unwell. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT let this chemical enter the environment.

Cool. Dry. Keep in a well-ventilated room. Separated from strong oxidants, strong bases and strong acids. 

IMPORTANT DATA
Physical State; Appearance
WHITE SOLID IN VARIOUS FORMS WITH PUNGENT ODOUR. 

Physical dangers
Dust explosion possible if in powder or granular form, mixed with air. If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc. 

Chemical dangers
Decomposes on heating and on contact with acids, bases and oxidants. This produces flammable formaldehyde. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation and by ingestion. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of short-term exposure
The substance is severely irritating to the eyes, skin and respiratory tract. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. See Notes. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 120-180°C
Relative density (water = 1):

Vapour pressure, kPa at 25°C: <0.2
Relative vapour density (air = 1): 1.03
Flash point: 71°C c.c.
Auto-ignition temperature: 300°C
Explosive limits, vol% in air: 7.0-73.0 
The substance is harmful to aquatic organisms. 

NOTES
Also consult ICSC 0275 (formaldehyde).
