3. Hazards Identification
OSHA status: This material is considered hazardous by the OSHA Hazard Communication Standard (CFR
1910.1200).
Routes of entry: Eye contact, skin contact, inhalation and ingestion
Potential acute health effects:
EYES: Severe eye irritant which may result in redness, burning, tearing and blurred vision.
SKIN: Skin irritant which may result in burning sensation. Repeated or prolonged skin contact may cause
dermatitis.
INGESTION: Ingestion may result in mouth, throat and gastrointestinal irritation, nausea, vomiting and
diarrhea.
INHALATION: Inhalation of spray mist or liquid vapors may cause upper respiratory irritation and possible
central nervous system effects including headaches, nausea, vomiting, dizziness, drowsiness, loss of
coordination, impaired judgment and general weakness.
Potential chronic health effects:
CARCINOGENIC EFFECTS:
Styrene: Classified A4 (not classifiable for human or animal) by ACGIH. Classified 2B (possible for human)
by IARC. An increased incidence of lung tumors was observed in mice from a recent inhalation study. The
relevance of this finding is uncertain since data from other long-term animal studies and from epidemiology
studies of workers exposed to styrene do not provide a basis to conclude that styrene is carcinogenic to
humans. Lung effects have been observed in mouse studies following repeated exposure.
Silica, Amorphous: Classified 3 (not classifiable for human) by IARC.
Cobalt Compounds: Classified A3 (proven for animal) by ACGIH. Classified 2B (possible for human) by
IARC.
Mutagenic or teratogenic effects: No known effect according to our database.

4. First Aid Measures
Inhalation: Remove source(s) of contamination and move victim to fresh air. If breathing has stopped, give
artificial respiration, then oxygen if needed. Contact physician immediately.
Eye Contact: Flush eyes with plenty of water. If irritation persists, seek medical attention.
Skin Contact: In case of skin contact, wash thoroughly with soap and water; remove contaminated clothing
and launder before reuse; seek medical attention if rash develops.
Ingestion: Do not induce vomiting unless instructed by a physician. Contact physician
Immediately
After first aid, get appropriate in-plant, paramedic, or community medical support.
5. Fire Fighting Measures
Flash Point: 87.6°F (31°C)
Auto-ignition temp: 914˚F (490˚C)
LEL: 0.9%
UEL: 6.8% (Styrene)
Flammability Classification: Flammable Liquid, Class 1C
Extinguishing Media: Water Fog, Dry Chemical, and Carbon Dioxide Foam Unusual Fire or Explosion
Hazards: Hazardous decomposition products may be formed. Avoid water contamination in closed containers
or confined areas as exothermic heat and carbon dioxide can evolve.
Fire-Fighting Instructions: Fire fighters should wear self-contained breathing apparatus. Do not release runoff
from fire control methods to sewers or waterways.
Fire-Fighting Equipment: Because fire may produce toxic thermal decomposition products, wear a selfcontained
breathing apparatus (SCBA) with a full face piece operated in pressure demand or positive pressure mode.
6. Accidental Release Measures
Small Spill: Absorb with an inert material and place in an appropriate waste disposal container
Large Spill: Contain and absorb large spills onto an inert, non-flammable adsorbent carpet (such as earth or
sand). Shovel into open-top drums or plastic bags for further decontamination of necessary. Wash the spill
area clean with a liquid decontaminant. Remove and properly dispose of residues. Notify applicable
government authorities if release is reportable (See CERCLA in Section 15).
7. Handling and Storage
Handling Precautions: Minimize breathing of vapors and avoid prolonged or repeated contact with skin. Wear
proper protective equipment. If ventilation is not sufficient, wear proper respiratory equipment. Avoid moisture
contamination. Reseal partial containers. Use good general housekeeping procedures.
Storage Requirements: Store in cool dry, well-ventilated area.

Respiratory Protection: Follow OSHA respirator regulations 29 CFR 1910.134 and European Standard EN
149; wear an MSHA/NIOSH or European Standard EN149 approved respirator.
Protective Clothing/Equipment: Wear chemically protective gloves to prevent prolonged or repeated skin
contact. Wear protective eyeglasses or chemical safety goggles, per OSHA eye and face protection
regulations 29 CFR 1910.133 and European Standard EN166. Contact lenses are not eye protective devices.
Appropriate eye protection must be worn instead of, or in conjunction with contact lenses.
Comments: Never eat, drink, or smoke in work areas. Practice good personal hygiene after using this
material, especially before eating, drinking, smoking, using the toilet, or applying cosmetics
