2 Safety Regulations

Paragraph 0, Point 01 of EN 50176:2009 is applicable to the elds of application of the apparatus.

This Standard also denes the design requirements for safe operation of the apparatus and the

electrical installation, including the forced ventilation.

The constructional requirements for the spray booth, dened in Standard EN 12215:2005, are also

applicable. This applies particularly to the identication of explosion hazardous areas.

This stipulates that the apparatus may only be used in areas where forced ventilation ensures that

during

• the application of ammable liquid coating materials, the average concentration of solvents

in the form of ammable vapour remains below 50% of the lower explosion limit (LEL) (EN

50176:2009, Para. 5.2).

Pursuant to EN 50176:2009, Para. 5.1.2/5.1.3, the apparatus is classied as a spraying system

type C-L or D-L when operated with electrostatic application equipment. This depends on the type

of installation and the local conditions.

In accordance with Para. 5.2.8 of EN 50176:2009, type C-L or D-L spraying systems must be tted

with a locally applied extinguishing system which may also be operated manually.

Section 5.2 of EN 50176:2009 must be observed. The requirements under 5.3 of EN 50176:2009

must be observed, in addition, if the apparatus is used as a 2G apparatus.

2.3 Electrostatic automatic spray gun

This electrostatic automatic spray gun meets the requirements of EN 50176:2009 – Stationary

electrostatic application equipment for ignitable liquid coating material – Safety requirements.

This Operating Manual deals only with the dangers typically associated with the automatic coat-

ing process when electrostatic spray guns in the described form are used under the conditions as

specied by the manufacturer.

These electrostatic spray guns are classied as Group II, Category 2 equipment pursuant to Di-

rective 94/9/EC, intended for use in explosive atmospheres generated by their own spray cloud.

Equipment in this category is intended for use in areas where an explosive atmosphere comprising

of gases, vapours, mist or dust/air mixtures may on occasion be expected.

2 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 afxed 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 rst 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 am-

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)

2 Safety Regulations

2.7 Work stations

• Ensure all sources of ignition are avoided. Smoking and open ames are prohibited in re and

explosion hazardous areas.

• Ensure that coating material deposits are kept to a minimum in spray booths, spray stands and

in the entire work area.

• Instruct and check that access doors to spray booths are kept closed during spraying.

2.8 Interior coating of hollowware

• Interior coating of hollowware inside of which hazardous conditions may arise due to gases,

mist or dust produced by coating materials is prohibited unless special safety measures are

taken.

2.9 Cleaning

• Coating material deposits must be removed at appropriate intervals. Special attention must to

this end be given to the cleaning of spray booths and their ventilation equipment, spray-paint

mist separators (if used), and their surroundings.

• The workpiece supports must be cleaned regularly to ensure good earthing of the workpieces.

• Ensure that the forced ventilation is operational during cleaning.

• Use only electrically conducting vessels for cleaning uids. These vessels must also be

earthed.

• Use only solvents with ash points at least 5K higher than ambient.

• Ensure that the discharge energy is < 0.24 mJ before starting with cleaning work using am-

mable solvents on live components. In practice this means that the system must be securely

earthed (see also 2.9).

2.10 Prerequisites to accessing spray booths

• Ensure that solvent concentrations in the air which these persons may inhale are below health

hazardous limits.

• Ensure that the oor of the spray booth is electrically conducting.

• Ensure that no persons are present in the spray booth during painting.

• Ensure that the discharge energy is < 350 mJ if contact with high voltage circuit components

is possible. The safe time between switching off the high voltage and possible contact with live

components must be stipulated in due consideration of the operational and local conditions.

• Ensure that the discharge energy of the high voltage circuit is < 0.24 mJ if ammable liquids

are used (see also 2.8.5) for cleaning.

S-AGR08-Egb02 05/15 - 3 Page 6 of 10

2 Safety Regulations

2.11 Personal protective gear

• Ensure that persons working with electrostatic spraying systems and any persons present on

the electrically conducting oor wear antistatic shoes.

• Where protective gloves are required, these must be antistatic or have similar properties.

2.12 Working with ignition risk

• The operating company shall ensure that no work involving risk of ignition is carried out in re

and explosion hazardous areas. Exceptions are possible, provided special protective meas-

ures (e.g. removing coating material, solvents and other ammable goods, cleaning equipment

and building sections beforehand, ensuring adequate ventilation etc.) are taken.

• Ensure that work involving risk of ignition which is carried out near openings to explosion haz-

ardous rooms and areas is only performed if it can be assured that sources of ignition cannot

enter such rooms and areas.
