SECTION 3: HAZARD IDENTIFICATION
Emergency Overview: White, opaque paste; no odor. This product is nonflammable. Paste will cause acute but mild irritation of the eyes and skin under repeated or
prolonged exposure.
Potential Health Effects:
Eyes: Product is irritating and can cause acute but mild tearing, reddening accompanied by a stinging sensation.
Skin: Contact with product can cause acute but mild skin irritation.
Ingestion: Irritating to mouth, throat and stomach. May cause vomiting, acute abdominal pain and diarrhea.
Inhalation: No known health effects from inhalation.
Pre-Existing Medical Conditions Aggravated by Exposure: Skin, eye.
SECTION 4: FIRST AID MEASURES
Eyes: Immediately flush with plenty of water. After initial flushing, remove any contact lenses and continue flushing for at least 15 minutes. Have eyes examined
and tested by medical personnel if irritation develops persists.
Skin: Flush affected area well with water. Wash skin with soap and water. Remove contaminated clothing. Get medical attention if irritation develops or persists.
Wash clothing separately before reuse.
Ingestion: Do not induce vomiting, but give one or two glasses of water to dilute material and get immediate medical attention.
Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
SECTION 5: FIRE FIGHTING MEASURES
掳
Flash Point: >500 F (260C) (TCC) LEL/UEL: Not established (% by volume in air)
Extinguishing media: Use alcohol foam, carbon dioxide, water spray, or dry chemical when fighting fires involving this material.
Fire Fighting Instructions: As in any fire, wear self-contained breathing apparatus (pressure-demand, OSHA/NIOSH approved or equivalent) and full protective gear.
Cool fire-exposed containers with water.
SECTION 6: ACCIDENTAL RELEASE MEASURES
Large Spills: Shut off leak if possible and safe to do so. Wear self-contained breathing apparatus and appropriate personal protective equipment. Absorb spill with
inert material (e.g. dry sand or earth), then place in a chemical waste container for proper disposal. Do not flush to sewer. Avoid runoff into storm sewers and ditches
which lead to waterways.
Small Spills: Absorb spill with inert material (e.g. dry sand or earth), then place in a chemical waste container for proper disposal.
SECTION 7: HANDLING AND STORAGE
Avoid prolonged or repeated contact of product with eyes, skin, and clothing. Wash hands before eating. Use with adequate ventilation. Avoid breathing dried product
dust. Do not reuse this container. Store in a cool dry place away from heat, sparks and flame. Keep container closed when not in use. Do not store in direct sunlight.
KEEP OUT OF REACH OF CHILDREN.
SECTION 8: EXPOSURE CONTROLS/PERSONNEL PROTECTION
Exposure Guidelines:
CHEMICAL NAME ACGIH TLV OSHA PEL OTHER
Polymethyldisiloxane NA NA NA
Zinc Oxide 2 mg/m3 (dust) 15 mg/m3 (dust) 10 mg/m3 (dust) STEL
Fumed Silica 10 mg/m3 (PNOC dust) NA 6 mg/m3 OEL
NA = not available
PNOC = Particles not otherwise classified
Work/Hygienic Practices: Good general ventilation should be sufficient to control airborne levels. Local exhaust ventilation may be necessary to control any air
contaminants to within their TLVs during the use of this product. If vapor concentration exceeds TLV, use NIOSH approved organic vapor cartridge respirator. Wear
safety glasses with side shields (or goggles) and rubber or other chemically resistant gloves when handling this material.
