Try to stop release.
6.3. Methods and material for containment and cleaning up
Methods and material for containment and
cleaning up
: Keep area evacuated and free from ignition sources until any spilled liquid has evaporated
(ground free from frost).
6.4. Reference to other sections
See also sections 8 and 13.
SECTION 7: Handling and storage
7.1. Precautions for safe handling
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. Suck back of water into the container must be prevented.
Open valve slowly to avoid pressure shock.
Safe use of the product : Assess the risk of potentially explosive atmospheres and the need for explosion-proof
equipment. Purge air from system before introducing gas. Take precautionary measures
against static discharge. Keep away from ignition sources (including static discharges).
Consider the use of only non-sparking tools. Ensure equipment is adequately earthed. The
product 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. Use only
properly specified equipment which is suitable for this product, its supply pressure and
temperature. Contact your gas supplier if in doubt. Avoid suck back of water, acid and alkalis.
Do not breathe gas. Avoid release of product into atmosphere.
7.2. Conditions for safe storage, including any incompatibilities
Conditions for safe storage, including any
incompatibilities
: Segregate from oxidant gases and other oxidants in store. All electrical equipment in the
storage areas should be compatible with the risk of a potentially explosive atmosphere.
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.
SECTION 8: Exposure controls/personal protection
8.1. Control parameters
No additional information available
8.2. Appropriate engineering controls
Appropriate engineering controls : Provide adequate general and local exhaust ventilation. Product to be handled in a closed
system. Gas detectors should be used when flammable gases/vapours may be released.
Consider the use of a work permit system e.g. for maintenance activities. Systems under
pressure should be regularily checked for leakages. Ensure exposure is below occupational
exposure limits (where available).
