Safety Regulations
2.3.1 Forced ventilation
Pursuant to EN 50176:2009, Section 5.4, the AGR-08-E electrostatic spray gun may only be used
in spraying areas with forced or equivalent conditions of ventilation.
This means that the maximum concentration of 50% of the lower explosion limit (LEL) of the coat
-
ing material to be applied may not be exceeded in the spraying areas.
The effectiveness of forced ventilation must be assured using special measures.
2.4
General demands for safe operation
•
To guarantee safe operation of the spraying equipment and its accessories, the operating com
-
pany must compile operating instructions, taking into account this Operating Manual. These
operating instructions must be available in the appropriate language and at the appropriate
location at the workplace.
•
Such operating instructions must point out that the electrostatic spraying equipment may only
be operated by trained persons.
•
A warning sign must be affixed in an obvious location near the spraying area, in a language
the user understands. This warning sign must explain the most important types of operation
and protective measures which the operators should comply with. The dangers involved in the
cleaning of spray guns must furthermore be clearly highlighted.
•
The first start-up of the equipment by the operator is allowed only after the initial test run by an
authorised specialist before the risk passes to the operator (BetrSichV [Ordinance on Industrial
Safety and Health] §14).
2.5 Instruction
It must be ensured that persons working with the electrostatic spraying system are instructed on
the inherent dangers and the measures necessary for prevention of these, before starting to oper-
ate the electrostatic coating equipment and accessories. These instructions should be repeated at
least once a year.
2.6
Use of electrostatic spraying systems in potentially explosive areas
•
The type AGR-08-E electrostatic spraying systems (spray guns) may only be operated in areas
in which the explosive conditions are caused exclusively by own electrostatic spraying of flam
-
mable liquid coating materials.
•
Electrostatic spraying systems may only be operated provided protective measures are taken
to protect from typical hazards of the tasks. Protective measures against electrical shock must
furthermore be taken by:
– avoiding unnecessary work on live parts of the plant
– disconnecting from mains
– suitable working clothing
– securing against accidental switch-on
– ensuring that power is off
– earthing and shorting
– access control (vehicle permission)
