WORKERS' HEALTH AND SAFETY
The European Union has issued some directives concerning the safety and health of workers, including: 89/391/EEC, 89/686/EEC, 2009/104/EC,
86/188/EEC and 77/576/EEC and subsequent amendments which every employer is obliged to follow and have followed. We observe therefore
that:
It is forbidden to tamper with or replace parts of the unit without the express authorisation of the manufacturer. This inter
-
vention releases the manufacturer from any civil or criminal liability.
Using components, consumables or spare parts that do not correspond to those recommended by the manufacturer and/or
listed in this manual may be dangerous for the operators and/or damage the unit.
The operator’s workplace must to be kept clean, tidy and clear of objects that may restrict free movement. Appropriate
lighting of the work place shall be provided so as to allow the operator to carry out the required operations safely. Poor or
excessive lighting can cause risks.
Ensure that work places are always adequately ventilated and that the extraction systems are working, in good condition
and in compliance with the requirements of the laws in force.
In the design phase, the indications contained in UNI EN ISO 14738 regarding workstations on the machinery were followed
and the lifting limits imposed by UNI ISO 11228-1 were evaluated.
Make sure to maintain, during the installation and maintenance of the unit, a posture that does not cause fatigue. Check the
weight, before moving any component.
The unit works with R32 refrigerant, which is included in the list of greenhouse gases (GWP 675) which are subject to the requirements in EU
regulation n. 517/2014 called “F-GAS” (mandatory in the European zone). Among the provisions of this regulation, imposes on operators working
in installations operating with greenhouse gases to hold a certificate, issued or recognised by the competent authority, certifying that they have
passed an examination authorising them to carry out such work. In particular
•
Up to 3kg total refrigerant in the appliance: category 2 certification.
•
3 kg and more total refrigerant in the appliance: category 1 certification.
The gaseous form of R32 refrigerant is heavier than air and if released into the environment, most of it tends to concentrate in poorly ventilated
areas. Inhaling it can cause dizziness and sensations of suffocation and can develop lethal gas if in contact with naked flames or hot objects (see
the refrigerant’s safety data sheet).
Pay attention to the fact that refrigerant fluids can be odourless.
For any operation on the heat pump system:
Wear the appropriate PPE (specifically gloves and goggles).
Make sure that the workplace is well ventilated. Do not work in closed environments or ditches with little air circulation.
Do not operate on the refrigerant in the vicinity of hot parts or naked flames.
Avoid any leakage of refrigerant into the environment and pay particular attention to accidental leaks from pipes and/or
fittings even after the system is emptied.
Make sure that there is a fire extinguisher near the unit.
4.2
PERSONAL PROTECTIVE EQUIPMENT
Personal protective equipment must be used when operating and mainteining the units, such as:
Clothing: Maintenance technicians and operators must wear protective clothing that does not leave parts of the body
uncovered, as during maintenance it is possible to come into contact with hot or sharp surfaces. Clothes that can become en
-
tangled or sucked in by airflows should be avoided. In case of slippery floors, they must also wear safety shoes with non-slip
soles.
Wear safety shoes with non-slip soles, especially in ambient with slippery floor.
Gloves: During maintenance or cleaning operations, appropriate protective gloves must be used.
