For all the units which allow access to the cooling piping without security gratings (optional) or closing panels, the
following precautions must be taken:
- mark the areas with contact risks
- apply warning signs
The danger zone must be of a suitable size to avoid any contact, even accidental contact.

PRECAUTIONS AGAINST RISKS DUE TO THE REFRIGERANT
Splashes or sprinkles can cause chill burns. The risk of absorptions through the skin is not relevant.
R410a refrigerant could take some lightly irritating effects and in liquid stage it has a strong skinning effect. In this case it is
necessary to rinse with fresh water the contaminated parts of the skin
refrigerant in liquid stage in contact with wet fabrics cause freezing and adherence to the skin. In this case it is necessary to
put off the contaminated clothes to avoid freezing. Please contact a doctor in case of irritation of the contaminated parts.
Risks for contact with the
eyes
Vapors don’t take any effect. Splashes or sprinklers can cause chill burns. In those cases it is necessary to
the eyes with water or with solution for ocular washings for 10 minutes. The intervention of a doctor is needed.
Should it happen, it causes chill burns. It does not cause vomiting. The person must be kept awake. It is needed to rinse the
esh water and to drink almost 0.25 liters. The intervention of a doctor is needed.
High concentration of vapors in air can lead to an
esthetic effects up to a loss of conscience. Long exposures could give
rise to cardiac arrhythmia and sometimes even to death.
High concentrations can create a reduction of oxygen in air, with consequent possibility of suffocation. Should it happen the
person must be taken to the open air and let him take a rest.
Administer oxygen if needed. In case the breathing has
interrupted or become irregular, it is necessary to
apply the artificial breathing. In case of cardiac arrest a heart massage must be applied. Contact a doctor immediately.
