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 heart-
beat 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. Liquid splashes can cause frostbite.
Ingestion
While highly improbable, may produce frostbite.
First aid measures
Inhalation
Move the injured away from the exposure source area and keep warm and at rest. Administer oxygen if necessary. Attempt artificial respiration if breath-
ing 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
1.10. 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" and "Tank&Pump" set-ups are related to the performance of the
pumps, which must always be checked by means of the HITECSA. selection software.
