First Aid Measures
Emergency procedures for chemical exposure incidents
Remove to fresh air. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Get medical attention. If not breathing, give artificial respiration.
Wash off immediately with plenty of water for at least 15 minutes. Get medical attention.
Symptoms: May cause allergic skin reaction. Symptoms of allergic reaction may include rash, itching, swelling, tingling of the hands and feet.
Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Get medical attention.
Do NOT induce vomiting. Call a physician or poison control center immediately.
Immediate Medical Attention
Get medical attention.
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
Fine dust dispersed in air may ignite. Do not allow run-off from fire-fighting to enter drains or water courses.
Firefighter Protection
As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear. Thermal decomposition can lead to release of irritating gases and vapors.
Accidental Release Measures
Spill cleanup procedures, containment, and environmental protection
Do not flush into surface water or sanitary sewer system. Do not allow material to contaminate ground water system. Prevent product from entering drains. Local authorities should be advised if significant spillages cannot be contained.
Sweep up and shovel into suitable containers for disposal.
Materials: suitable containers
