SECTION 2: Hazards identification

Emergency Overview: Pellets or powder with slight to no odor. Combustion and decomposition may produce hazardous fumes. Base resin dust/powder has a US Bureau of Mines relative dust explosion hazard rating of severe. Molten material can cause thermal burns on contact with skin or eyes. Spilled pellets may create a slipping hazard. Overheating may result in release of formaldehyde, which may irritate the eyes and respiratory tract.

Principle Routes of Exposure

Skin and eye contact; inhalation of vapors, if overheated. Signs and Symptoms of No specific information available concerning exposure to the product. If formaldehyde is Exposure: released as an off-gas, a burning sensation and tearing of the eyes may occur. An irritating odor may be noted. Immediate Effects: Skin: Hot or molten material has the potential to cause thermal burns. Polymer particles can cause mechanical irritation. Formaldehyde, which may be generated if overheated, may cause skin sensitization, an allergic reaction, which becomes evident on reexposure. Eyes: No specific information available on the product. Polymer particles can cause mechanical irritation. Degradation vapors may cause irritation. Inhalation: No specific information available on the product. Pellets are not considered an inhalation hazard; polymer dust/flake may be considered an inert nuisance particulate. Formaldehyde, which may be released if overheated, may cause irritation of the upper respiratory tract. Ingestion: No specific information available on the product, however, low toxicity by this route is expected based on the biological activity of high molecular weight polyacetal polymers. Long Term/Delayed Effects: No specific information available on the product. Formaldehyde may cause respiratory sensitization. Carcinogenicity: No specific information available on the product. Formaldehyde, which is a degradation product, is listed as a potential cancer hazard by OSHA, a known human carcinogen by The International Agency for Research on Cancer (IARC, Group 1), and a substance which can reasonably be anticipated to be a carcinogen by The National Testing Program (NTP). Formaldehyde should not pose a risk if exposures are kept below the OSHA Permissible Exposure Limit.

Medical Conditions Generally Aggravated by Exposure

No specific information available on the product. Off-gases, which may be released if overheated, may affect those with chronic diseases of the respiratory system.
