3.1 - GENERAL SAFETY INSTRUCTIONS
WARNING!
The equipment described in this manual is:
• a device subjected to pressure in pressurised systems;
• normally installed in systems carrying ammable gases (for example: natural gas).
WARNING!
If the gas used is a combustible gas, the installation area of the equipment is dened as a “danger zone”
as there are residual risks that potentially explosive atmospheres may be generated.
There must not be any effective sources of ignition in “danger zones”
• and in close proximity thereto;
• no smoking.
ATTENTION!
Authorised operators must not carry out operations or services on their own initiative that do not fall with-
in their competence.
Never operate the equipment:
• while under the inuence of intoxicating substances such as alcohol;
• if you are using drugs that may lengthen reaction times.
NOTE!
The employer must train and inform operators on how to behave during operations and on the equipment
to be used.
Before installation, commissioning or maintenance, operators must:
• take note of the safety regulations applicable to the place of installation that they are working in;
• obtain the necessary permits to operate when required;
• equip themselves with the necessary personal protection required in the procedures described in this manual:
• ensure that the area that they are operating in is equipped with the required collective protections and the necessary
safety information.
