FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. Paint or
solvent flowing through the system can cause static sparking. To help prevent fire or explosion:
• Electrostatic equipment must be used only by trained, qualified personnel who understand
the requirements of this manual.
• Ground all equipment, personnel, object being sprayed, and conductive objects in or close to
the spray location. Resistance must not exceed 1 megohm. See Grounding instructions.
• Do not use pail liners unless they are conductive and grounded.
• Always use the required arc detection settings and maintain a safe distance of at least 6
inches (152 mm) between the applicator and the workpiece.
• Stop operation immediately if static sparking or repeated arc detection errors occur. Do not
use equipment until you identify and correct the problem.
• Check applicator resistance and electrical grounding daily.
• Use and clean equipment only in a well ventilated location.
• Always turn off and discharge the electrostatics when flushing, cleaning or servicing
equipment.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and
plastic drop cloths (potential static arc).
• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.
• Keep the spray area clean at all times. Use non-sparking tools to clean residue from the
booth and hangers.
• Keep a working fire extinguisher in the work location.
• Interlock the gun air and fluid supply to prevent operation unless ventilation air flow is above
the minimum required value.
• Interlock the Electrostatic Controller and fluid supply with the booth ventilation system to
disable operation if the air flow falls below minimum values. Follow your local codes.
For solventborne systems only:
Use only Group IIA or Group D materials.
• Use cleaning solvents with highest possible flash point when flushing or cleaning equipment.
• To clean the exterior of the equipment, cleaning solvents must have a flash point at least 15°C
(59°F) above ambient temperature. Non-ignitable fluids are preferred.
For waterborne systems only:
Use conductive waterborne fluids that meet at least one of the following conditions for
non-flammability:
• Material does not sustain burning in accordance with the Standard Test Method for Sustained
Burning of Liquid Mixtures, ASTM D4206.
• Material is classified as non-ignitable or hard to ignite as defined by EN 50176.
