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.
