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. Clear all other personnel 
from the area. Walking surface contact may present a slipping/falling 
hazard. Polypropylene 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 polypropylene is a surface burning material. 
If applied in a high-pressure stream, water may spread the burning 
surface layer, and may be immediately converted to scalding steam. 
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. Keep above 
burning material. Notify authorities if liquid enters sewer/public 

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 polypropylene. 

INGESTION: No significant signs or symptoms indicative of any 
adverse health effect are expected to occur as a result of ingestion. 

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. 

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 

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

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
