Section 3: Hazard Identification
Emergency Overview
Aluminum viscous liquid. Can cause headache, irritation, nausea, drowsiness, stupor, coughing spell, and allergic respiratory sensitization. Leave area to breathe fresh air. Should be observed by physician immediately if overexposure is severe.
Routes of Entry
Ingestion: Yes; Inhalation: Yes; Skin: Yes; Eye: Yes
Inhalation
Can cause headache, irritation, nausea, drowsiness, stupor, coughing spell, and allergic respiratory sensitization.
Ingestion
Can cause gastrointestinal irritation.
Skin
Can cause irritation, sensitization, and dermititis. Can be absorbed through skin.
Eye
Can cause irritation.
Medical Conditions Aggravated by Exposure
Pre-existing eye, skin, and respiratory disorders may be aggravated by exposure.
Accute Health Effects
See effects described above.
Chronic Health Effects
Reports have associated repeated and prolonged occupational overexposure to solvents with permanent brain and nervous system damage. Intentional misuse by deliberately concentrating and inhaling contents may be harmful or fatal. Prolonged or repeated contact to xylene and/or ethylbenzene may cause defatting, drying, and irritation of the skin, dermititis, CNS effect described above, heart muscle sensitization and arrhythmia, hearing loss, and brain, liver, kidney, and testes damage. Prolonged xylene overexposure may affect fetal development. The risk of the effects of xylene should be insignificant in well-ventilated areas. A long-term NTP study showed that oral exposure to toluene diisocyanate (TDI) caused cancer in rats and mice. A lifetime inhalation study sponsored by the International Isocyanated Institute did not show carcinogenic activity in rats. Diphenylmethane diisocyanate(methylene bisphenyl isocyanate) caused an increased incidence of lung tumors in experimental animals following ong-term inhalation at concentrations in excess of 100 times the exposure limit. Overexposure to isocyanate can cause a decrease in lung function. Skin and respiratory sensitization is possible. Inhalation of crystalline silica (quartz) can cause cancer based on animal data, and IARC concludes sufficient evidence in humans (Group 1). Prolonged and repeated overexposure to free crystalline silica dust above the TLV level may cause scarring of the lungs with cough and shortness of breath. A delayed lung injury, silicosis, may result from breathing free silica. Fillers are encapsulated and not expected to be released from product under normal conditions of use.
Section 4: First Aid Measures
Inhalation
Leave area to breathe fresh air. Should be observed by a physician immediately if overexposure is severe.
Ingestion
Get medical attention immediately.
Skin
Wash area of contact thoroughly with hand cleaner followed by soap and water. If irritation, rash, or other disorders develop, get medical attention immediately.
Eye
Flush immediately with running water for 15 minutes, lifting the upper and lower lids occasionally. Get medical attention immediately.
Section 5: Fire-Fighting Measures
Flash Point
103°F setaflash
Explosive Range
Lower limit: not established, Upper limit: not established
Extinguishing Media
If water fog is ineffective, use carbon dioxide, dry chemical, or foam.
Fire and Explosion Hazards
Never use welding or cutting torch on or near container (even empty). Product, residue, or vapor may ignite. See Section 7 for additional precautions.
Fire-Fighting Procedures
During a fire, personnel at the scene are to prevent exposure to fumes using accepted fire-fighting techniques.
Fire-Fighting Equipment
Not applicable.
Other Precautions
Hydrocyanic acid, oxides of nitrogen can form.
Section 6: Accidental Release Measures
Release Response Overview
Remove sources of ignition immediately. Ventilate to reduce the airborne containment concentration below the exposure limit in Section 8 of the MSDS. Absorb spill in sand, earth, or other suitable material. Transfer to appropriate container for disposal.
Section 7: Handling and Storage
Handling and Storage
Store in closed container below 80°F. Keep product and vapor away from heat, sparks, and flame. Do not store in direct sunlight. Prevent inhalation of vapor, ingestion, and contact with skin and eyes. Keep container closed when not in use. Vapor may migrate to sources of ignition. Do not smoke, weld, generate sparks, or use flame near container. Change soiled work clothes frequently. Clean hands thoroughly after handling. Precautions also apply to emptied containers. Personal protective equipment must be worn during maintenance or repair of contaminated mixer, reactor, or other equipment.
