First Aid Measures
Emergency procedures for chemical exposure incidents
Remove to fresh air. If not breathing, give artificial respiration. Get medical attention if symptoms occur.
Wash off immediately with plenty of water for at least 15 minutes. If skin irritation persists, call a physician.
Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Get medical attention.
Clean mouth with water and drink afterwards plenty of water. Get medical attention if symptoms occur.
Medical Treatment
Treat symptomatically.
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Water spray, carbon dioxide (CO2), dry chemical, alcohol-resistant foam.
No information available
Thermal decomposition can lead to release of irritating gases and vapors. Keep product and empty container away from heat and sources of ignition.
Firefighter Protection
As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear.
Accidental Release Measures
Spill cleanup procedures, containment, and environmental protection
Should not be released into the environment. See Section 12 for additional Ecological Information.
