APPENDIX: SAFETY DATA R410A
REFRIGERANT DATA
SAFETY DATA: R410A
Toxicity
Low
Contact with Skin
R410 A vapours can irritate the skin and eyes. In liquid form, it can freeze skin on contact. If contact with skin
occurs, flush the exposed area with lukewarm water until all of the chemical is removed. If there is evidence of
frostbite, bathe in lukewarm water.
Contact with Eyes
If contact with eyes occurs, immediately flush with large amounts of lukewarm water for at least 15 minutes,
lifting eyelids occasionally to facilitate irrigation. Seek medical attention as soon as possible.
Ingestion
Very unlikely - should something happen, it will cause frost burns. Do not induce vomiting. Only if the patient is
conscious, wash out mouth with water and give some 250 ml of water to drink. Then, obtain medical attention.
Inhalation
Inhalation of the R410A vapour may cause irritation. Vapour inhalation at high concentrations may result in
asphyxiation or the heart may become sensitized, causing cardiac arrhythmia. When concentration of R410A
reach levels which reduce oxygen to 14-16% by displacement, symptoms of asphyxiation will occur. An
individual exposed to high concentrations of R410A must be given medical attention immediately. Adequate
ventilation must be provided at all times.
Recommendations
Semiotics or support therapy is recommended. Cardiac sensitisation has been observed that, in the presence of
circulating catecholamines such as adrenalin, may cause cardiac arrhythmia and accordingly, in case of
exposure to high concentrations, cardiac arrest.
Prolonged Exposure
R410A: a study on the effects of exposure to 50,000 ppm during the whole life of rats has identified the
development of benign testicle tumour.
This situation should therefore be negligible for personnel exposed to concentrations equal to or lower than
professional levels.
Professional Levels
R410A: Recommended threshold: 1000 ppm v/v - 8 hours TWA.
Stability
R410A: without specifying
Conditions to Avoid
Do not use in the presence of high temperatures, flames, burning surfaces and excess humidity.
Hazardous Reactions
Contact with certain red-hot metals may result in exothermic or explosive reactions and yield toxic and/or
corrosive decomposition products. Specific materials to avoid include freshly abraded aluminium surfaces and
active metals such as sodium, potassium, calcium, powdered aluminium, magnesium and zinc.
Hazardous
Decomposition
Products
R410A: Halogen acids produced by thermal decomposition and hydrolysis.
General Precautions
Do not inhale concentrated vapours. Their concentration in the atmosphere should not exceed the minimum
preset values and should be maintained below the professional threshold. Being weightier than the air, the
vapour concentrates on the bottom, in narrow areas. Therefore, the exhaust system must work at low level.
Respiratory System
Protection
If you are in doubt about the concentration in the atmosphere, it is recommended to wear a respirator approved
by an accident prevention Authority, of the independent or oxygen type.
Storage
Cylinders must be stored in a cool, dry and properly ventilated storage area away from heat, flames, corrosive
chemicals, flumes, explosives and be otherwise protected from damage. Keep a temperature below 50°C.
Protective Clothing
Wear overalls, protective gloves and goggles or a mask.
Accidental Release
Measures
It is important to wear protective clothing and a respirator. Stop the source of the leak, if you can do this without
danger. Negligible leaks can be left evaporating under the sun, providing that the room is well ventilated.
Considerable leaks: ventilate the room. Reduce the leak with sand, earth or other absorbing substances. Make
sure that the liquid does is not channeled into gutters, sewers or pits where the vapours are likely to create a
stuffy atmosphere.
Disposal
The best method is recovery and recycling. If this method is not practicable, dispose according to an approved
procedure, which shall ensure the absorption and neutralization of acids and toxic agents.
Fire Fighting
Information
R410A: Not flammable in the atmosphere.
Cylinders
The cylinders, if exposed to fire, shall be cooled by water jets; otherwise, if heated, they may explode.
Protective Fire
Fighting Equipment
In case of fire, wear an independent respirator and protective clothing.
