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 long-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. |
|
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. |

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. |
|
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. |
|
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. |
