- Water

- powder

- Foam

- Dry chemical

- Carbon dioxide (CO2)

2. Unsuitable extinguishing media:

- None.

SPECIFIC HAZARDS ARISING FROM THE CHEMICAL

- The product is not flammable.

- Not explosive

- The pressure in sealed containers can increase under the influence of heat.

- Explosive reaction may occur on heating or burning.

- In case of fire hazardous decomposition products may be produced such as: Gaseous hydrogen fluoride (HF), Fluorophosgene

SPECIAL PROTECTIVE ACTIONS FOR FIRE_FIGHTERS

- Wear self-contained breathing apparatus and protective suit.

- When intervention in close proximity wear acid resistant over suit.

- Evacuate personnel to safe areas.

- Approach from upwind.

- Protect intervention team with a water spray as they approach the fire.

- Keep containers and surroundings cool with water spray.

- Keep product and empty container away from heat and sources of ignition.

Accidental release measures

PERSONAL PRECAUTIONS, PROTECTIVE EQUIPMENT AND EMERGENCY PROCEDURES

1. Advice for non-emergency personnel

- Prevent further leakage or spillage if safe to do so.

2. Advice for emergency responders

- Ensure adequate ventilation.

- Vapours are heavier than air and can cause suffocation by reducing oxygen available for breathing.

- Keep away from open flames, hot surfaces and sources of ignition.

- Refer to protective measures listed in sections 7 and 8.

ENVIRONMENTAL PRECAUTIONS:

- Should not be released into the environment.

METHODS AND MATERIALS FOR CONTAINMENT AND CLEANING UP:

- Soak up with inert absorbent material.

- Suitable material for picking up

- Earth

- Dry sand

- Shovel into suitable container for disposal.

Handling and storage

PRECAUTIONS FOR SAFE HANDLING:

- Ensure adequate ventilation.

- Use personal protective equipment.

- Keep away from heat and sources of ignition.

- To avoid thermal decomposition, do not overheat.

- Take measures to prevent the build up of electrostatic charge.

- Clean and dry piping circuits and equipment before any operations.

- Ensure all equipment is electrically grounded before beginning transfer operations.

CONDITIONS FOR STORAGE, INCLUDING INCOMPATIBILITIES:

1. Storage

- Keep in properly labelled containers.

- Vapours are heavier than air and may spread along floors.

- Keep away from heat and sources of ignition.

- Keep away from combustible material.

- Keep away from Incompatible products.

- Provide tight electrical equipment well protected against corrosion.

- Refer to protective measures listed in sections 7 and 8.

2. Packaging material

Suitable material:

- Stainless steel

- Plastic material

- Maximum filling degree: 90% at 20°C

Exposure controls / personal protection

CONTROL PARAMETERS

Exposure Limit Values:

Ethane, 1,1,2,2-tetrachloro-1,2-difluoro-

- US. ACGIH Threshold Limit Values 01 2010

time weighted average = 50 ppm

EXPOSURE CONTROLS

1. Appropriate engineering controls:

- Ensure adequate ventilation.

- Refer to protective measures listed in sections 7 and 8.

- Apply technical measures to comply with the occupational exposure limits.

2. Individual protection measures:

2.1. Respiratory protection

- Use respirator when performing operations involving potential exposure to vapour of the product.

- The filter class for the respirator must be suitable for the maximum expected contaminant concentration (gas/vapour/aerosol/particulates) that may arise when handling the product. If this concentration is exceeded, self-contained breathing apparatus must be used.

- Use only respiratory protection that conforms to international/ national standards.

- Remove respiratory and skin/eye protection only after vapours have been cleared from the area.

2.2. Hand protection

- Rubber gloves

- Take note of the information given by the producer concerning permeability and break through times, and of special workplace conditions (mechanical strain, duration of contact).

2.3. Eye protection

- Tightly fitting safety goggles

2.4. Skin and body protection

- Long sleeved clothing

- Choose body protection in relation to its type, to the concentration and amount of dangerous substances, and to the specific work-place.

2.5. Hygiene measures

- Ensure that eyewash stations and safety showers are close to the workstation location.

- When using do not eat, drink or smoke.

- Wash hands before breaks and at the end of workday.

- Handle in accordance with good industrial hygiene and safety practice.

3. Environmental exposure controls:

- Dispose of rinse water in accordance with local and national regulations.
