First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

Move to fresh air. Get medical attention 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

Skin contact

Wash off immediately with plenty of water for at least 15 minutes. Get medical attention if symptoms occur.

Eye contact

Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Obtain medical attention.

Ingestion

Do not induce vomiting. Obtain medical attention.

Immediate Medical Attention

Obtain medical attention.

Medical Treatment

Treat symptomatically

05

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

CO₂, dry chemical, dry sand, alcohol-resistant foam.

Unsuitable media

Water may be ineffective

Specific hazards

Flammable. Risk of ignition. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Containers may explode when heated. Thermal decomposition can lead to release of irritating gases and vapors. Keep product and empty container away from heat and sources of ignition.

Instructions

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.

06

Accidental Release Measures

Spill cleanup procedures, containment, and environmental protection

Emergency procedures

Use personal protective equipment. Remove all sources of ignition. Take precautionary measures against static discharges. Avoid contact with skin, eyes and clothing. Ensure adequate ventilation.

Environmental

Avoid release to the environment. See Section 12 for additional ecological information.

Cleanup methods

Soak up with inert absorbent material. Keep in suitable, closed containers for disposal. Use spark-proof tools and explosion-proof equipment.

Materials: inert absorbent material

07

Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

Wear personal protective equipment. Ensure adequate ventilation. Use spark-proof tools and explosion-proof equipment. Avoid contact with skin, eyes and clothing. Avoid ingestion and inhalation. Keep away from open flames, hot surfaces and sources of ignition. Take precautionary measures against static discharges. Use only non-sparking tools. To avoid ignition of vapors by static electricity discharge, all metal parts of the equipment must be grounded.

Storage

Keep containers tightly closed in a dry, cool and well-ventilated place. Keep away from heat and sources of ignition. Flammables area.

Hygiene

Avoid contact with skin, eyes and clothing. Avoid ingestion and inhalation.

Fire prevention

Keep away from open flames, hot surfaces and sources of ignition. Take precautionary measures against static discharges. Use only non-sparking tools. All metal parts of the equipment must be grounded.
