Pressroom Safety - page 11

All maintenance procedures that involve removing or replacing equipment on the press or expose personnel to
hazardous moving mechanisms require that lockouts and tags be used on the power disconnects for all types of
power involved. Lockouts may be required on more than one power source due to the various kinds of equipment
: High Voltages are present when incoming AC power is connected. Make all changes to the equipment
with the main disconnect locked in the "OFF" position. Failure to follow this procedure may cause
serious personal injury, death, and/or equipment damage. (CAUTION: Some presses have multiple
disconnects, and all of them should be locked off.)
: Press equipment should be installed, adjusted, and serviced by qualified electrical maintenance
personnel familiar with the operation of the equipment and the potential hazards. Failure to follow this
practice may cause serious personal injury, death, and/or equipment damage.
: Observe the following safety procedures as well as the National Electrical Code recommendations,
and your plant procedures, when working on press equipment. Disregarding these precautions may
cause serious personal injury, death, and possible equipment damage.
1. "
" means to place a lock on the main power disconnect after turning off the switch. Be sure to
understand when lockouts are needed. See
information section.
2. "
" means to place an identification tag on the main power disconnect (switch) after it is turned off.
The tag should identify the person who locked it out as well as the area being serviced. Tagouts should be
applied to all electrical devices where a lockout has been applied for maintenance work. Tags must be
removed when the work is completed and the lock is removed.
3. Never make adjustments to the electrical system until you are sure all personnel are clear of rotating and
moving parts.
4. Safety devices should never be jumped or defeated in any way. These devices are designed to protect
personnel and equipment.
5. To avoid the danger of electrical shock, all maintenance personnel should use only insulated tools on
electrical and electronic equipment.
6. Employ extreme caution when using electronic instruments for testing and troubleshooting circuits with the
power on. Even low voltages under the right conditions can be lethal. Keep one hand in a pocket when
servicing live equipment and avoid bracing yourself against the equipment.
7. Always check circuits for electrical voltages since capacitors can retain charges that cause electric shock
when the power switches are in the “OFF” position.
8. Jewelry (rings, wristwatches, bracelets, key chains, etc.) should not be worn while working with electrical and
electronic equipment. Insulated boots and gloves must be worn when the danger of high voltage electrical
shock is present.
9. Never stand or sit on a wet surface when troubleshooting or maintaining electrical and electronic equipment.
10. Do not allow fluids of any kind to leak or spill into electrical or electronic circuits.
11. Spark arcs from electrical equipment can present a fire hazard if flammable solvents are nearby. Use extreme
caution to prevent ignition possibilities.
NOTE: Arcing occurs inside the main drive motor as part of its normal operation. Clean the filter regularly, and be
extra careful to keep flammables away from this area (i.e. paper dust).
