Section 7 - HANDLING AND STORAGE
PROCEDURE FOR HANDLING
• Vented gas is more dense than air and may collect in pits, basements.
• Consider use in closed pressurised systems, fitted with temperature, pressure and safety relief valves which are vented for
safe dispersal.
• The tubing network design connecting gas cylinders to the delivery system should include appropriate pressure indicators and
vacuum or suction lines.
• Fully-welded types of pressure gauges, where the bourdon tube sensing element is welded to the gauge body, are recommended.
• Before connecting gas cylinders, ensure manifold is mechanically secure and does not containing another gas. Before
disconnecting gas cylinder, isolate supply line segment proximal to cylinder, remove trapped gas in supply line with aid of
vacuum pump.
• DO NOT transfer gas from one cylinder to another.
SUITABLE CONTAINER
Cylinder: Steel packaging
Ensure the use of equipment rated for cylinder pressure.
Ensure the use of compatible materials of construction.
Valve protection cap to be in place until cylinder is secured, connected.
Cylinder must be properly secured either in use or in storage.
Cylinder valve must be closed when not in use or when empty.
Segregate full from empty cylinders.
WARNING: Suckback into cylinder may result in rupture. Use back-flow preventive device in piping.
STORAGE INCOMPATIBILITY
Haloalkanes:
• are highly reactive:some of the more lightly substituted lower members are highly flammable; the more highly substituted may be
used as fire suppressants, not always with the anticipated results.
• may react with the lighter divalent metals to produce more reactive compounds analogous to Grignard reagents.
• may produce explosive compounds following prolonged contact with metallic or other azides
• may react on contact with potassium or its alloys - although apparently stable on contact with a wide rage of halocarbons,
reaction products may be shock-sensitive and may explode with great violence on light impact; severity generally increases
with the degree of halocarbon substitution and potassium-sodium alloys give extremely sensitive mixtures .
• Avoid reaction with oxidising agents.
STORAGE REQUIREMENTS
• Cylinders should be stored in a purpose-built compound with good ventilation, preferably in the open.
• Such compounds should be sited and built in accordance with statutory requirements.
• The storage compound should be kept clear and access restricted to authorised personnel only.
• Cylinders stored in the open should be protected against rust and extremes of weather.

MATERIAL DATA
A-GAS R134A:

TETRAFLUOROETHANE:
Sensory irritants are chemicals that produce temporary and undesirable side-effects on the eyes, nose or throat. Historically
occupational exposure standards for these irritants have been based on observation of workers' responses to various airborne
concentrations.
May act as a simple asphyxiants; these are gases which, when present in high concentrations, reduce the oxygen content in air

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
below that required to support breathing, consciousness and life; loss of consciousness, with death by suffocation may rapidly
occur in an oxygen deficient atmosphere.
CARE: Most simple asphyxiants are odourless or possess low odour and there is no warning on entry into an oxygen deficient
atmosphere.
Studies show that HFC 134a is practically nontoxic by inhalation. The acute lethal effects occur at levels exceeding 500000
ppm whilst the threshold for cardiac sensitisation occurs at about 75000 ppm. Repeated exposures at 50000 ppm for 13 weeks did
not produce significant toxicity in animals. Limited studies have shown the substance not to be a carcinogen, or to exhibit
mutagenic effects. Exposures up to 300000 ppm and 40000 ppm did not produce teratogenic effects in rats and rabbits respectively.
The workplace environmental exposure level (WEEL), recommended by the AIHA, is thought to be protective against cardiac
sensitisation and systemic injury.
PERSONAL PROTECTION
RESPIRATOR
•Type AX Filter of sufficient capacity. (AS/NZS 1716 & 1715, EN 143:2000 & 149:2001, ANSI Z88 or national equivalent)
EYE
• Chemical goggles.
• Full face shield may be required for supplementary but never for primary protection of eyes
• Contact lenses may pose a special hazard; soft contact lenses may absorb and concentrate irritants. A written policy document,
describing the wearing of lens or restrictions on use, should be created for each workplace or task. This should include a
review of lens absorption and adsorption for the class of chemicals in use and an account of injury experience. Medical and
first-aid personnel should be trained in their removal and suitable equipment should be readily available. In the event of
chemical exposure, begin eye irrigation immediately and remove contact lens as soon as practicable. Lens should be removed at
the first signs of eye redness or irritation - lens should be removed in a clean environment only after workers have washed
hands thoroughly. [CDC NIOSH Current Intelligence Bulletin 59], [AS/NZS 1336 or national equivalent].
HANDS/FEET
• When handling sealed and suitably insulated cylinders wear cloth or leather gloves.
• Insulated gloves:
NOTE: Insulated gloves should be loose fitting so that may be removed quickly if liquid is spilled upon them.
OTHER
• Positive pressure, full face, air-supplied breathing apparatus should be used for work in enclosed spaces if a leak is
suspected or the primary containment is to be opened (e.g. for a cylinder change)
• Air-supplied breathing apparatus is required where release of gas from primary containment is either suspected or demonstrated.
• Protective overalls, closely fitted at neck and wrist.
• Eye-wash unit.
• Ensure availability of lifeline in confined spaces.
• Staff should be trained in all aspects of rescue work.
ENGINEERING CONTROLS
■ Engineering controls are used to remove a hazard or place a barrier between the worker and the hazard. Well-designed
engineering controls can be highly effective in protecting workers and will typically be independent of worker interactions to
provide this high level of protection.
The basic types of engineering controls are:
Process controls which involve changing the way a job activity or process is done to reduce the risk.
Enclosure and/or isolation of emission source which keeps a selected hazard "physically" away from the worker and ventilation
that strategically "adds" and "removes" air in the work environment.

Section 11 - TOXICOLOGICAL INFORMATION
■ Inhalation of non-toxic gases may cause:• CNS effects: headache, confusion, dizziness, stupor, seizures and coma;•
respiratory: shortness of breath and rapid breathing;•
cardiovascular: collapse and irregular heart beats;•
gastrointestinal: mucous membrane irritation, nausea and vomiting.
■ The material is not thought to produce respiratory irritation (as classified by EC Directives using animal models).
Nevertheless inhalation of the material, especially for prolonged periods, may produce respiratory discomfort and occasionally,
distress.
■ Material is highly volatile and may quickly form a concentrated atmosphere in confined or unventilated areas.
The vapour
may displace and replace air in breathing zone, acting as a simple asphyxiant.
■ Exposure to fluorocarbons can produce non-specific flu-like symptoms such as chills, fever, weakness, muscle pain, headache,
chest discomfort, sore throat and dry cough with rapid recovery.
High concentrations can cause irregular heartbeats and a stepwise reduction in lung capacity.
■ Acute intoxication by halogenated aliphatic hydrocarbons appears to take place over two stages.
Signs of a reversible narcosis are evident in the first stage and in the second stage signs of injury to organs may become
evident, a single organ alone is (almost) never involved.
CHRONIC HEALTH EFFECTS
Principal route of occupational exposure to the gas is by inhalation.
Substance accumulation, in the human body, may occur and may cause some concern following repeated or long-term occupational
exposure.
Fluorocarbons can cause an increased risk of cancer, spontaneous abortion and birth defects.
