SECTION 5: Firefighting measures
- Suitable extinguishing media : Water spray or fog.
- Unsuitable extinguishing media : Do not use water jet to extinguish.
Specific hazards : Exposure to fire may cause containers to rupture/explode.
Hazardous combustion products : None that is more hazardous than the product itself.
Specific methods : Use fire control measures appropriate for the surrounding fire. Exposure to fire and heat
radiation may cause gas receptacles to rupture. Cool endangered receptacles with water spray
jet from a protected position. Prevent water used in emergency cases from entering sewers and
drainage systems.
If possible, stop flow of product.
Use water spray or fog to knock down fire fumes if possible.
Move containers away from the fire area if this can be done without risk.

apparatus.
Ensure adequate air ventilation.
Prevent from entering sewers, basements and workpits, or any place where its accumulation
can be dangerous.
Act in accordance with local emergency plan.
Stay upwind.
Environmental precautions
Try to stop release.
Reduce vapour with fog or fine water spray.
Methods and material for containment and cleaning up
Hose down area with water.
Ventilate area.
Wash contaminated equipment or sites of leaks with copious quantities of water.
Handling and storage
Precautions for safe handling
Safe use of the product : The substance must be handled in accordance with good industrial hygiene and safety
procedures.
Only experienced and properly instructed persons should handle gases under pressure.
Consider pressure relief device(s) in gas installations.
Ensure the complete gas system was (or is regularily) checked for leaks before use.
Do not smoke while handling product.
Avoid exposure, obtain special instructions before use.
Use only properly specified equipment which is suitable for this product, its supply pressure and
temperature. Contact your gas supplier if in doubt.
Installation of a cross purge assembly between the cylinder and the regulator is recommended.
Purge system with dry inert gas (e.g. helium or nitrogen) before gas is introduced and when
system is placed out of service.
Avoid suck back of water, acid and alkalis.
Do not breathe gas.
Avoid release of product into atmosphere.
Safe handling of the gas receptacle : Refer to supplier's container handling instructions.
Do not allow backfeed into the container.
Protect cylinders from physical damage; do not drag, roll, slide or drop.
When moving cylinders, even for short distances, use a cart (trolley, hand truck, etc.) designed
to transport cylinders.
Leave valve protection caps in place until the container has been secured against either a wall
or bench or placed in a container stand and is ready for use.
If user experiences any difficulty operating cylinder valve discontinue use and contact supplier.
Never attempt to repair or modify container valves or safety relief devices.
Damaged valves should be reported immediately to the supplier.
Keep container valve outlets clean and free from contaminants particularly oil and water.
Replace valve outlet caps or plugs and container caps where supplied as soon as container is
disconnected from equipment.
Close container valve after each use and when empty, even if still connected to equipment.
Never attempt to transfer gases from one cylinder/container to another.
Never use direct flame or electrical heating devices to raise the pressure of a container.
Do not remove or deface labels provided by the supplier for the identification of the cylinder
contents.
Conditions for safe storage, including any incompatibilities
Observe all regulations and local requirements regarding storage of containers.
Containers should not be stored in conditions likely to encourage corrosion.
Container valve guards or caps should be in place.
Containers should be stored in the vertical position and properly secured to prevent them from
falling over.
Stored containers should be periodically checked for general condition and leakage.
Keep container below 50°C in a well ventilated place.
Store containers in location free from fire risk and away from sources of heat and ignition.
Keep away from combustible materials.

Exposure controls / personal protection
Appropriate engineering controls
: Product to be handled in a closed system and under strictly controlled conditions.
Provide adequate general and local exhaust ventilation.
Preferably use only permanent leak-tight installations (e.g. welded pipes).
Systems under pressure should be regularily checked for leakages.
Ensure exposure is below occupational exposure limits (where available).
Gas detectors should be used when toxic gases may be released.
Consider work permit system e.g. for maintenance activities
Individual protection measures, e.g. personal protective equipment
A risk assessment should be conducted and documented in each work area to assess the risks
related to the use of the product and to select the PPE that matches the relevant risk. The
following recommendations should be considered:
PPE compliant to the recommended EN/ISO standards should be selected.
• Eye/face protection : Wear safety glasses with side shields.
Wear goggles and a face shield when transfilling or breaking transfer connections.
Standard EN 166 - Personal eye-protection.
Provide readily accessible eye wash stations and safety showers.
• Skin protection
- Hand protection : Wear working gloves when handling gas containers.
Standard EN 388 - Protective gloves against mechanical risk.
Wear chemically resistant protective gloves.
Standard EN 374 - Protective gloves against chemicals.
Consult glove manufacturer´s product information on material suitability and material thickness.
The breakthrough time of the selected gloves must be greater than the intended use period.
- Other : Wear safety shoes while handling containers.
Standard EN ISO 20345 - Personal protective equipment - Safety footwear.
Keep suitable chemically resistant protective clothing readily available for emergency use.
Standard EN943-1 - Full protective suits against liquid, solid and gaseous chemicals.
• Respiratory protection : Gas filters may be used if all surrounding conditions e.g. type and concentration of the
contaminant(s) and duration of use are known.
Use gas filters and full face mask, where exposure limits may be exceeded for a short-term
period, e.g. connecting or disconnecting containers.
Recommended: Filter B (grey).
Consult respiratory device supplier´s product information for the selection of the appropriate
device.
Gas filters do not protect against oxygen deficiency.

Keep self contained breathing apparatus readily available for emergency use.
Standard EN 137 - Self-contained open-circuit compressed air breathing apparatus with full
face mask.
Self contained breathing apparatus is recommended, where unknown exposure may be
expected, e.g. during maintenance activities on installation systems.
Stability and reactivity
