Avoid inhalation of high concentrations of vapour. The atmospheric concentration must be reduced as far as possible and maintained at this minimum level,
below professional exposure limits. The vapours are heavier than air, and thus hazardous concentrations may form close to the floor, where overall ventila-
tion may be poor. In this case, ensure adequate ventilation. Avoid contact with naked flames and hot surfaces, which could lead to the formation of irritant
and toxic decomposition by-products. Do not allow the liquid to come into contact with eyes or skin.
• Procedures in case of accidental refrigerant leakage
Ensure adequate personal protection (using means of respiratory protection) during clean-up operations. If the conditions are sufficiently safe, isolate the
source of leak. If the extent of the spill is limited, let the material evaporate, as long as adequate ventilation can be ensured. If the spill is considerable, venti-
late the area adequately. Contain the spilt material with sand, soil, or other suitable absorbent material. Prevent the liquid from entering drains, sewers,
underground facilities or manholes, because suffocating vapours may form.
❑ Main toxicological information on the type of refrigerant used
• Inhalation
A high atmospheric concentration can cause anaesthetic effects with possible loss of consciousness. Prolonged exposure may lead to an irregular heartbeat
and cause sudden death. Higher concentrations may cause asphyxia due to the reduced oxygen content in the atmosphere.
• Contact with skin and eyes
Splashes of nebulised liquid can produce frostbite. Probably not hazardous if absorbed through the skin. Repeated or prolonged contact may remove the
skin's natural oils, with consequent dryness, cracking and dermatitis. Splashes of nebulised liquid can produce frostbite.
• Ingestion
While highly improbable, may produce frostbite.
First aid measures
• Inhalation
Move the person away from the source of exposure, keep him/her warm and let him/her rest. Administer oxygen if necessary. Attempt artificial respiration if
breathing has stopped or shows signs of stopping. In the case of cardiac arrest carry out heart massage and seek immediate medical assistance.
• Contact with skin and eyes
In case of contact with skin, wash immediately with lukewarm water. Thaw tissue using water. Remove contaminated clothing. Clothing may stick to the skin
in case of frostbite. If irritation, swelling or blisters appear, seek medical assistance. Rinse immediately using an eyewash or clean water, keeping eyelids
open, for at least ten minutes. Seek medical assistance.
• Ingestion
Do not induce vomiting. If the injured person is conscious, rinse his/her mouth with water and make him/her drink 200-300 ml of water. Seek immediate
medical assistance.
• Further medical treatment
Treat symptoms and carry out support therapy as indicated. Do not administer adrenaline or similar sympathomimetic drugs following exposure, due to the
risk of cardiac arrhythmia.
• Extinguishing media
Suitable extinguishing media:
o NEBULISED WATER
o DRY POWDER
Unsuitable extinguishing media:
o JETS OF WATER
o CO2
1.3. PERMITTED TEMPERATURE DIFFERENTIALS THROUGH THE HEAT EXCHANGERS
Evaporator temperature differential ΔT = 3 ÷ 8°C with "Standard" set-ups. However, consider the minimum and maximum flow rates reported in the tables
"Water flow rate limits". The maximum and minimum temperature differentials for "Pump" set-ups are related to the performance of the pumps, which must
always be checked by means of the selection software.
