Tetrahydrofuran 99.7% HPLC – Firefighting Measures
Extinguishing Media: Use personal protective equipment. Avoid breathing vapours, mist or gas. Ensure adequate ventilation.
Remove all sources of ignition. Evacuate personnel to safe areas. Beware of vapours accumulating to form explosive concentrations. Vapours can accumulate in low areas.
Hazards Arising: No Data Available
Advice for Firefighters: Wear self-contained breathing apparatus for firefighting if necessary.Info for Firefighting: Use water spray to cool unopened containers.

Accidental Release Measures
Personal Precautions: No Data Available
Enviromental Precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains.
Method for Containment: Contain spillage, and then collect with non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite) and place in container for disposal according to local / national regulations.

Handling and Storage
Personal Precautions: Avoid contact with skin and eyes. Avoid inhalation of vapour or mist. Keep away from sources of ignition – No smoking. Take measures to prevent the build up of electrostatic charge.
Enviromental Precautions: Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Store in cool place. Dry residue is explosive. Store under inert gas. Test for peroxide formation periodically and before distillation.

Body Protection: Complete suit protecting against chemicals, Flame retardant antistatic protective clothing., The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.
Respiratory Protection: Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multipurpose combination (US) or type AXBEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).
