Section 3: Hazards Identification

Primary Route(s) of Entry Into Body
Inhalation and ingestion

Acute Effects

Eyes
Dust particles may cause mechanical irritation.

Skin
Direct contact may cause slight skin irritation.

Inhalation
May cause respiratory discomfort similar to inhalation of too much "inert" dust.

Chemical Name/Synonyms
Modified EPS, Modified Foam Polystyrene

Ingestion
Biologically inert.

Chronic Effects in Humans
No known adverse effects.

Section 4: First Aid Measures

Eye contact
Hold eyelids open and flush immediately with gentle stream of water for at least 15 minutes.
* Seek medical attention if irritation persists.

Skin contact
Wash exposed areas with mild soap and water.

Inhalation
Move person to fresh air. If breathing is difficult, seek medical attention.

Ingestion
Not likely to cause serious injury if ingested.

Section 5: Fire Fighting Measures

Flash Pt. and Method Used
6750 F (ASTM D-1929 per bead manufacturers)
Special Fire Fighting Instructions: Use self-contained breathing apparatus respirator and approved personal protective clothing.

Extinguishing Media
Water fog, carbon dioxide, foam, and dry chemical.

Auto-Ignition Temperature
8800 F (ASTM D-1929 per bead manufacturers)

Unusual Fire and Explosion Hazards
Combustion causes dense, black smoke. Smoke consists of carbon monoxide, carbon dioxide and styrene. Other undetermined hydrocarbon fractions could be released in small quantities.

Section 7: Handling and Storage

Storage
Although expanded polystyrene contains a fire retardant additive, it is considered combustible and adequate protection from sources of ignition should be taken.

Section 16: Other Information

Expanded Polystyrene materials sold for construction use have a fire retardant modifier, but are considered combustible, as are all organic materials. They must not be stored or installed near open flame or any other source of ignition. In addition, when EPS insulation is installed in the interior of a structure, it must be protected by a proper thermal barrier and the installer must review applicable local, state, and federal building codes to determine the correct thermal barrier for the particular application.
