01/03/2020 EN (English) 3/9
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 :
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
:
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
Pentafluoroethane (354-33-6)
Not applicable
Difluoromethane (R32) (75-10-5)
Not applicable
8.2. Appropriate engineering controls
Appropriate engineering controls :
Provide adequate general and local exhaust ventilation. Oxygen detectors should be used
when asphyxiating gases may be released. Systems under pressure should be regularily
checked for leakages. Ensure exposure is below occupational exposure limits (where
available). Consider the use of a work permit system e.g. for maintenance activities.
Environmental exposure controls :
Refer to local regulations for restriction of emissions to the atmosphere. See section 13 for
specific methods for waste gas treatment.
8.3. Individual protection measures/Personal protective equipment
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.
Hand protection:
Wear cold insulating gloves when transfilling or breaking transfer connections. Standard EN 511 - Cold insulating gloves. Wear working gloves
when handling gas containers. Standard EN 388 - Protective gloves against mechanical risk.
Eye protection:
Wear goggles when transfilling or breaking transfer connections. Standard EN 166 - Personal eye-protection - specifications
