First Aid Measures
Emergency procedures for chemical exposure incidents
Remove to fresh air. If breathing is irregular or stopped, administer artificial respiration.
Symptoms: Difficulty in breathing. 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.
Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes.
Do NOT induce vomiting. Call a physician or poison control center immediately.
Immediate Medical Attention
Immediate medical attention is required.
Medical Treatment
Treat symptomatically
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Water spray. CO₂, dry chemical, dry sand, alcohol-resistant foam. Water mist may be used to cool closed containers.
Water may be ineffective, Do not use a solid water stream as it may scatter and spread fire
Flammable. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Containers may explode when heated. Vapors may form explosive mixtures with air.
Water mist may be used to cool closed containers.
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
Evacuate personnel to safe areas. Keep people away from and upwind of spill/leak.
Should not be released into the environment.
Soak up with inert absorbent material.
Materials: inert absorbent material

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Wear personal protective equipment/face protection. Ensure adequate ventilation. Keep away from open flames, hot surfaces and sources of ignition. Take precautionary measures against static discharges. Do not get in eyes, on skin, or on clothing. Do not breathe mist/vapors/spray. Use spark-proof tools and explosion-proof equipment. Use only non-sparking tools. To avoid ignition of vapors by static electricity discharge, all metal parts of the equipment must be grounded.
Keep container tightly closed in a dry and well-ventilated place. Keep away from heat, sparks and flame. Flammables area.
Do not get in eyes, on skin, or on clothing. Do not breathe mist/vapors/spray.
Keep away from open flames, hot surfaces and sources of ignition. Take precautionary measures against static discharges. Use spark-proof tools and explosion-proof equipment. Use only non-sparking tools. To avoid ignition of vapors by static electricity discharge, all metal parts of the equipment must be grounded.
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.
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: low boiling organic solvent. Type AX. Brown. conforming to EN371.
Wear appropriate protective clothing to prevent skin exposure.
