******************************************
3. Fire & Explosion Hazard Data
******************************************

Flash Point:............. >800F (450C)
Flammable Limits in Air:..Not Applicable
Autoignition Temp:........No data available
NFPA Rating: Health (1) Fire (1) Reactivity (0)
(Applies only to exposure during a fire)

FIRE AND EXPLOSION HAZARDS: Heat from fire may melt and decompose 
polymer, generating flammable vapors. Fire fighters should wear 
self-contained breathing apparatus in the positive pressure mode 
when there is a possibility of exposure to smoke, fumes, or hazardous 
decomposition products. Water, if applied in a high-pressure stream, 
will spread the burning surface layer. Clear all other personnel from 
the area. Walking surface contact may present a slipping/falling 
hazard. Polyethylene dust particles in the atmosphere are combustible 
and may be explosive. 

EXTINGUISHING MEDIA: CO2, Dry Chemical, Foam, or Water.

FIREFIGHTING PROCEDURES: Water should be applied as a spray from a 
fogging nozzle, since polyethylene is a surface burning material. 
Keep above burning material. Notify authorities if liquid enters 
sewer/public waters.

******************************************
4. Human Health Data
******************************************

INHALATION: Nuisance dust from this product may cause respiratory 
irritation following an excessive inhalation exposure. Follow 
exposure limits given below. Fumes may be generated in operations 
using heated polyethylene. 

INGESTION: Rats fed acute oral doses of 7.95 g/kg showed no evidence 
of adverse effects. Dietary levels of 1.25, 2.5, or 5% polyethylene 
for 90 days produced no evidence of adverse effects in rats. 

EYE CONTACT: Powder or dust may cause eye irritation.

SKIN CONTACT: Product can be abrasive and cause irritation. 
Molten or heated material can cause serious burns to 
unprotected skin. 

OCCUPATIONAL EXPOSURE LIMITS: PEL/TWA: No OSHA PEL for this product. 
For nuisance dust: 15 mg/m3 for total dust and 5 mg/m3 for respirable dust. 
TLV/TWA: No AGCIH TLV for this product. 
For nuisance particulates: 10 mg/m3 for total dust. 

******************************************
5. Preventative Measures
******************************************

ENGINEERING CONTROLS: Local exhaust and/or enclosures should be 
used to whenever feasible to maintain concentrations below acceptable 
limits.

RESPIRATORY: If engineering controls are not sufficient or feasible 
to maintain concentrations below exposure limits, use NIOSH/MSHA 
approved respiratory protection.

EYE: Dust service goggles should be worn to prevent mechanical 
injury or other irritation to eyes due to airborne particles which 
may result from handling this product.

SKIN: When use can result in skin contact, wear gloves and other 
protective clothing as required to prevent mechanical irritation 
or burns. Practice good personal hygiene. Wash hands and other 
exposed areas with mild soap and water before eating, drinking, 
smoking, and when leaving work.

OTHER HYGIENIC PRACTICES: Use good personal hygiene practices. Wash 
hands before eating, drinking, smoking, or using toilet. Promptly 
remove soiled clothing and wash thoroughly before reuse. Shower after 
work using plenty of soap and water.

OTHER WORK PRACTICES: Material spilled on hard surface can be a 
serious slipping/falling hazard. Use care in walking on spilled 
material. Clean areas where spills occur as soon as practical. 

******************************************
6. Emergency and First Aid Procedures
******************************************

INHALATION: If overcome by exposure, remove victim to fresh air 
immediately. Give oxygen or artificial respiration as needed. 
Obtain emergency medical attention. Prompt action is essential. 

EYE CONTACT: In case of eye contact with solid material, immediately 
rinse with clean water for 20-30 minutes. Retract eyelids often. 
Obtain emergency medical attention if pain, blinking, tears, or 
redness persist. 

SKIN CONTACT OR INGESTION: Skin contact or ingestion are not expected 
to present a significant hazard under anticipated conditions of normal 
use. 

******************************************
7. Additional Precautions in Handling, Storage, and Use
******************************************

Transfer from storage with a minimum of dusting. Ground all 
transfer, blending, mixing, and dust collection equipment to 
prevent static sparks. Remove all ignition sources from the 
material handling, transfer, and processing areas where dust 
may be present. 

******************************************
8. Environmental and Regulatory Data
******************************************

PRECAUTIONS IF MATERIAL IS SPILLED OR RELEASED: Creates slipping 
hazard on any hard surface. Potential dust explosion hazard from 
airborne release. Evacuate or limit access. Equip responders with 
proper protection (see Section 5, Preventative Measures). 
Extinguish all ignition sources. Stop release. Notify fire and/or 
environmental authorities. On land, sweep/shovel into suitable 
disposal containers. On water, material floats and is insoluble. 
Contain and collect as for any solid. Report per regulatory 
requirements. 

WASTE DISPOSAL METHODS: Comply with federal, state, and local 
regulations for solid waste disposal. Contaminated product, 
soil, or water should not be designated a RCRA hazardous waste 
unless contaminated with other materials.

TOXIC SUBSTANCES CONTROL ACT: This product is listed in the 
TSCA Inventory of Chemical Substances.

SARA HAZARD CATEGORIES: Immediate/Acute Health Hazard. Fire Hazard
