3. Hazards Identification.
Hazards Overview
Polyoxymethylene tends to generate formaldehyde gas during melting and residing in the cylinder
of the molding, extruding or other processing machine and during combustion and drying.
Adverse human health effects :
Do not use this material for implant articles.

There is not the environment influence that should be described.
Physical and Chemical hazards :
R10-Flammable.
Class name of hazardous chemicals for MSDS in Japan :
It is not classified as dangerous or harmful to nature.
It does not correspond to the classification standard.
4. First-Aid Measures
Inhalation :
S45-In case of inhalation of formaldehyde, seek medical advice immediately
(Show the product label where possible).
Affected person should be removed from the contaminated area immediately and taken to where
there is fresh air.
In case of inhalation of the gas from the molten polymer or in the case that the mood became
-2-
bad, transfer him in fresh air right away and wait for recovery.
In case that affected person does not recover, seek medical advices.
Skin contact :
If skin contact with molten polymer occurs, cool the affected part with cold water.
Do not try to remove the polymer by force- seek medical advice if burning has occurred.
Eye contact :
Gently rinse eyes with clean water for at least 15 minutes. (remove contact lenses if he is
wearing) Arrange for transportation to the nearest medical facility for examination and treatment
by a doctor as soon as possible.
Refrain from rubbing eyes.
In case of powder or pellets entering the eyes, rinse immediately with cold water. If discomfort
persists, consult a doctor.
Ingestion :
S45-In case of ingestion, seek medical advice immediately
(show the product label where possible).
Rinse mouth with water. Drink one or two glasses of water, and induce vomiting.
5. Fire-Fighting Measures
Extinguishing Media :
S43-In case of fire, use water mist, water jet, foam, dry powder, CO2,
Specific Hazards with regard to Fire-Fighting Measures :
S41-In case of fire and / or explosion do not inhale fumes.
During a fire, irritating and highly toxic gases may be generated by thermal decomposition or
combustion.
Toxic gases will form upon combustion of : carbon monoxide, carbon dioxide,
formaldehyde
Specific fire-fighting measures :
Apply water from a safe distance to cool and protect surrounding area.
Keep personnel removed from the area downwind of the fire.
Evacuate non-essential personnel to safe area.
Avoid pouring water onto molding machines.
Protection of fire-fighters :
Firefighters should wear proper protective equipment. (i.e. chemical-cartridge respirator ,gas
-3-
mask )
6. Accidental Release Measures
Measures for Handling Personnel :
Pellets on road or floor may cause slippage and falling.
Measures for environmental effects :
Do not flush into sewerage systems or waterways.
If pellets get released into the environment, take adequate steps to prevent aquatic animals and
birds from ingesting pellets.
Measures when handling spilled substances :
Sweep up, place in a bag and hold for waste disposal.
Preventive measures for secondary accident :
7. Handling and Storage
Handling :
Preventive measures :
Exposure control for handling personnel :
S20-Do not eat or drink whilst handling..
S21-Do not smoke during handling
S22-Do not inhale dust.
S23-Do not inhale gas, fumes
S51-Use only in well-ventilated areas.
Always provide adequate ventilation to maintain safe working environment.
Low levels of formaldehyde may remain in the headspace of bags. Bags of resin should be
opened in a well-ventilated area.
In case of drying resin, a drier equipped with a ventilator should be used.
Collect any spilled pellets from the floor to prevent slippage.
Protective measures against fire & explosion :
S33-Take precautionary measures against static discharges.
Shut off all gas pilot and electrical (spark or hot wire) igniters and other sources of ignition
during use and until all vapors(odors) are gone.
-4-
Do not subject to friction or shock.
Appropriate measures should be taken to control the generation and accumulation of d
ust during conveying and processing operations.
Safety Measures/ Incompatibility :
S29-Do not empty into drains.
S50-Do not mix with the following, in molding machine: acids, oxidizing agents, PVC
Incompatibility (Specific materials to be avoided) acids, oxidizing agents, PVC
Protect against physical damage.
Do not drop onto, or slide across sharp objects.
Avoid rough handling or dropping.
Avoid resin temperatures and residence times which may cause resin decomposition.
Do not heat resin to over 250鈩?
At shot-down, ensure that all resin has been expelled from the cylinder, nozzle, hot runner,
and other high temperature zones.
Always submerge purged resin in water immediately after purging, to prevent air
contamination of working environment.
Storage :
Incompatible storage conditions :
S15-Keep away from heat.
S16-Keep away from sources of ignition -No smoking.
Keep away from heat source, steam pipes, direct sunlight and store in a cool, dark place.
8. Exposure Control/Personal Protection
Engineering measures :
Atmospheric levels should be maintained below the exposure guidelines.
Powder handling should be carried out in a closed system.
When processing, partial ventilation is desirable to eliminate generated gas and dust.
