First-aid measures

Inhalation
- Remove to fresh air.
- Oxygen or artificial respiration if needed.

Fire-fighting measures

- Extinguishing medium: In case of fire in close proximity, all means of extinguishing are suitable.
- Hazards: Non-flammable.
- Container may explode if heated.
- Heating can release hazardous gases.

- Protective equipment: Self-contained breathing apparatus, full protective acid resistant suite.
- Unsuitable extinguishing medium: No restrictions

Special protective equipment for fire-fighters:
- Wear self-contained breathing apparatus and protective suit.
- Fire fighters must wear fire resistant personnel protective equipment.
- Wear chemical resistant oversuit
- Protect intervention team with a water spray as they approach the fire.
- Clean contaminated surface thoroughly

Other information
- Approach from upwind.
- Evacuate personnel to safe areas.
- Keep containers and surroundings cool with water spray.
- After the fire, proceed rapidly with cleaning of surfaces exposed to the fumes in order to limit equipment damage.

Accidental release measures

Personal precautions
- wear self-contained breathing apparatus in medium confinement/insufficient oxygen/in case of large uncontrolled emissions/in all circumstances when the mask and cartridge do not give adequate protection.
- Use only respiratory protection that conforms to international/ national standards.
- In the case of vapour formation use a respirator with an approved filter.
- Approach from upwind.
- Suppress (knock down) gases/vapours/mists with a water spray jet.
- Avoid spraying the leak source.
- Try to re-position leaking containers, to have the leak in the gaseous phase.
- Vapours are heavier than air and can cause suffocation by reducing oxygen available for breathing.
- Prevent further leakage or spillage if safe to do so.
- Keep away from open flames, hot surfaces and sources of ignition.
- Keep away from incompatible products
- Avoid release into the environment

Methods for cleaning up
- Allow to evaporate
- prevent product from entering drains

Handling and storage

Handling:
- Use in closed system
- Use only in well ventilated areas
- Use only equipment and materials which are compatible with the product.
- Prevent product vapours decomposition from electric arc action (welding).
- Prevent product vapours decomposition from contacting hot spots.
- Keep away from heat sources.

Storage requirement:
- Keep in a cool, well-ventilated place.
- Keep only in the original container at a temperature not exceeding 40 °C.
- Store in a receptacle equipped with a vent.
- Store in upright position only.

Packaging material: Steel drums

Occupational Exposure Limit:
8-h TWA TLV (ACGIH): 1,000 ppm. American Conference of Governmental Industrial Hygienists.

Stability and reactivity

Stability
- Stable under recommended storage conditions.
- Strong oxidizers, alkali metals and alkaline earth metals may cause fires or explosions.
- Vapours are heavier than air and may spread along floors.
- Hazardous Polymerisation/Polymerization: no
Conditions to avoid
- Heating
Materials to avoid
- Oxidizing agents
Hazardous decomposition products

- Gaseous hydrogen fluoride (HF).

Disposal considerations

Waste from residues / unused products
- In accordance with local and national regulations.
- Refer to manufacturer/supplier for information on recovery/recycling.
Packaging treatment
- To avoid treatments, as far as possible, use dedicated containers.
