Personal Safety 

To prevent injury follow these instructions.

S

Do not operate or service equipment unless you are qualified.

S

Do not operate equipment unless safety guards, doors, or covers are
intact and automatic interlocks are operating properly.  Do not bypass or

disarm any safety devices.

S

Keep clear of moving equipment.  Before adjusting or servicing moving

equipment, shut off the power supply and wait until the equipment

comes to a complete stop.  Lock out power and secure the equipment to

prevent unexpected movement.

S

Relieve (bleed off) hydraulic and pneumatic pressure before adjusting or

servicing pressurized systems or components.  Disconnect, lock out,

and tag switches before servicing electrical equipment.

S

While operating manual spray guns, make sure you are grounded.

Wear electrically conductive gloves or a grounding strap connected to

the gun handle or other true earth ground.  Do not wear or carry metallic

objects such as jewelry or tools.

S

If you receive even a slight electrical shock, shut down all electrical or

electrostatic equipment immediately.  Do not restart the equipment until

the problem has been identified and corrected.

S

Obtain and read Safety Data Sheets (SDS) for all materials used.

Follow the manufacturer’s instructions for safe handling and use of

materials, and use recommended personal protection devices.

S

Make sure the spray area is adequately ventilated.

S

To prevent injury, be aware of less-obvious dangers in the workplace
that often cannot be completely eliminated, such as hot surfaces, sharp

edges, energized electrical circuits, and moving parts that cannot be

enclosed or otherwise guarded for practical reasons.

High-Pressure Fluids 

High-pressure fluids, unless they are safely contained, are extremely

hazardous.  Always relieve fluid pressure before adjusting or servicing high

pressure equipment.  A jet of high-pressure fluid can cut like a knife and

cause serious bodily injury, amputation, or death.  Fluids penetrating the

skin can also cause toxic poisoning.

If you suffer a fluid injection injury, seek medical care immediately.  If

possible, provide a copy of the SDS for the injected fluid to the health care

provider.
