FIRE, EXPLOSION, OR ELECTROSTATIC SHOCK HAZARD

To reduce the risk of fire, explosion, or electrostatic shock, which may result from electrical discharge, it is essential that:

S All parts of the electrostatic system are properly grounded.

S All personnel in or close to the spray area are properly grounded.

SAll electrically conductive objects or devices in the spray area, including paint containers, wash cans and tools, are properly grounded.

When operating the electrostatic device, any ungrounded objects in the spray area (such as people, containers, tools, etc.) can become electrically charged. Arcing may occur if these objects then come in contact or close to ground. Arcing of suffi- cient energy levels can ignite the fluid being sprayed, fumes from solvents, dust particles, and other flammable substances. This can cause a fire, explosion, or electrostatic shock and re- sult in serious bodily injury and property damage.

Static electricity can also be generated by the flow of fluid through the pump, hose, gun, and nozzle, but it is dissipated through proper grounding as described in Grounding below.

If you experience any arcing or feel even a slight shock, STOP SPRAYING IMMEDIATELY. Check for proper grounding of the entire system. Be sure you have corrected the problem before starting to spray again.

Grounding

The following are minimum requirements for grounding a basic electrostatic system. Your system may include other equipment or objects which must also be grounded. Always check your local electrical code for detailed grounding instructions. Be sure your system is connected to a true earth ground.

1.Pump: ground by using a ground wire and clamp as described in your separate pump instruction manual.

2. Air compressors and hydraulic power supplies: ground according to the manufacturer’s recommendations.

3.Electrostatic Air Spray Gun: obtain grounding through con- nection to a properly grounded air supply hose. Use only the Graco Electrically Conductive Air Supply Hose; see ACCESSORIES section to order . Connect the air hose ground wire to a true earth ground.

4.Object being sprayed: keep the work piece hangers clean and grounded at all times. Contact points must be sharp points or knife edges.

5. All electrically conductive objects or devices in the spray area, including paint containers and wash cans, must be properly grounded.

6.All persons entering the spray area: shoes must have con- ductive soles, such as leather, or personal grounding straps must be worn. Rubber or plastic soles are not conductive.

7.The floor of the spray area must be electrically conductive and grounded. Do not cover the floor with cardboard or any non-conductive material which would interrupt grounding continuity.

8.Flammable liquids in the spray area must be kept in approved, grounded containers. Do not store more than the quantity needed for one shift.

9.All solvent pails: use only grounded metal pails, which are conductive. Do not place the pail on any non-conductive surface, such as cardboard or paper, which would interrupt grounding continuity.

10.All air and fluid lines and electric cables must be properly grounded.

Flushing and Cleaning Safety

To reduce the risk of static sparking or splashing, always follow the Pressure Relief Procedure on page 2 before flushing.

Be sure the turbine air (electrostatics) is OFF before flush- ing or cleaning any part of the spray system.

Use the lowest possible pressure to flush. Trigger the gun into a grounded metal waste container.

To flush or purge equipment, ALWAYS use solvents with a flash point equal to or greater than that of the fluid being sprayed.

To clean the exterior of the equipment, ALWAYS use solvents

with a flash point of higher than 100_ F (38_￿ C).

ALWAYS remove all solvent from the system before reactivating the spray gun.

Use only non-sparking tools to clean residue from the booth and hangers.

Ventilate the Spray Booth

To prevent hazardous concentrations of toxic and/or flammable vapors, spray only in a properly ventilated spray booth.

Check and follow all National, State and Local codes regarding air exhaust velocity requirements. Check and follow all local safety and fire codes and OSHA standard 1910.107.

NEVER operate the spray gun unless the ventilating fans are operating.

IMPORTANT

United States Government safety standards have been adopted under the Occupational Safety and Health Act. These standards––particularly the General Standards, Part 1910.107 and any other appropriate regulations––should be consulted in connection with the installation, operation, and maintenance of electrostatic spray painting equipment.
