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. Chemical 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.
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.

Wear personal protective equipment/face protection. Ensure adequate ventilation. Do not get in eyes, on skin, or on clothing. Avoid ingestion and inhalation. Avoid dust formation.
Keep in a dry, cool and well-ventilated place. Keep container tightly closed.
Do not get in eyes, on skin, or on clothing.
Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Ensure adequate ventilation, especially in confined areas. Ensure that eyewash stations and safety showers are close to the workstation location.
Wear appropriate protective gloves
Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced. Recommended Filter type: Particulates filter conforming to EN 143.
Wear appropriate protective clothing to prevent skin exposure.
