First Aid Measures
Emergency procedures for chemical exposure incidents
Move to fresh air. Get medical attention immediately if symptoms occur. If not breathing, give artificial respiration.
Symptoms: Breathing difficulties. Inhalation of high vapor concentrations may cause symptoms like headache, dizziness, tiredness, nausea and vomiting
Wash off immediately with plenty of water for at least 15 minutes. Get medical attention immediately if symptoms occur.
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. If vomiting occurs naturally, have victim lean forward.
Immediate Medical Attention
Get medical attention immediately if symptoms occur. Call a physician or Poison Control Center immediately.
Medical Treatment
Treat symptomatically.
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Cool closed containers exposed to fire with water spray.
Do not use a solid water stream as it may scatter and spread fire
Extremely flammable. Containers may explode when heated. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back.
Cool closed containers exposed to fire with water spray.
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.
Soak up with inert absorbent material. Keep in suitable, closed containers for disposal.
Materials: inert absorbent material

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Wear personal protective equipment. Avoid contact with skin, eyes and clothing. Avoid ingestion and inhalation. Keep away from open flames, hot surfaces and sources of ignition. Use only non-sparking tools.
Keep containers tightly closed in a dry, cool and well-ventilated place. Keep away from heat and sources of ignition. Refrigerator/flammables. Flammables area.
Keep away from open flames, hot surfaces and sources of ignition. Use only non-sparking tools.
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. Use explosion-proof electrical/ventilating/lighting/equipment.
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.
No protective equipment is needed under normal use conditions.
Wear appropriate protective clothing to prevent skin exposure.
