Safety Bulletin

SAFETY BULLETIN

This notice is issued to advise you that some previously accepted shop practices may not be keeping up

with changing Federal and State Safety and Health Standards. Your current shop practices may not

emphasize the need for proper precautions to insure safe operation and use of machines, tools, automatic

loaders and allied equipment and/or warn against the use of certain solvents or other cleaning substances

that are now considered unsafe or prohibited by law. Since many of your shop practices may not reflect

current safety practices and procedures, particularly with regard to the safe operation of equipment, it is

important that you review your practices to ensure compliance with Federal and State Safety and Health

Standards.

IMPORTANT

The operation of any machine or power-operated device can be extremely hazardous unless

proper safety precautions are strictly observed. Observe the following safety precautions:

Always be sure proper guarding is in place for all pinch, catch, shear, crush and nip points.

Always make sure that all personnel are clear of the equipment before starting it.

Always be sure the equipment is properly grounded.

Always turn the main electrical panel off and lock it out in accordance with published lockout/tag-

out procedures prior to making adjustments, repairs, and maintenance.

Always wear appropriate protective equipment like safety glasses, safety shoes, hearing

protection and hard hats.

Always keep chemical and flammable material away from electrical or operating equipment.

Always maintain a safe work area that is free from slipping and tripping hazards.

Always be sure appropriate safety devices are used when providing maintenance and repairs to all

equipment.

Never exceed the rated capacity of a machine or tool.

Never modify machinery in any way without prior written approval of the Besser Engineering

Department.

Never operate equipment unless proper maintenance has been regularly performed.

Never operate any equipment if unusual or excessive noise or vibration occurs.

Never operate any equipment while any part of the body is in the proximity of potentially haz-

ardous areas.

Never use any toxic flammable substance as a solvent cleaner.

Never allow the operation or repair of equipment by untrained personnel.

Never climb or stand on equipment when it is operational.

It is important that you review Federal and State Safety and Health Standards on a continual basis. All

shop supervisors, maintenance personnel, machine operators, tool operators, and any other person

involved in the setup, operation, maintenance, repair or adjustment of Besser-built equipment should read

and understand this bulletin and Federal and State Safety and Health Standards on which this bulletin is

based.

LOCKING OUT THE MACHINE

CAUTION: For safety reasons, it is

IMPORTANT for all personnel to read

and understand the following Lock-out

procedure.

Whenever you have to make adjustments, service

the machine, do any kind of checkup or stop pro-

duction of units, you must lock out the machine.

Locking out insures that the machine will not

start-up accidentally, thus preventing possible

grave injuries. It is a question of safety for all per-

sonnel.

When you have to lock out the machine, please

follow this procedure:

1. Announce lockout to other employees.

2. Turn power OFF at main panel.

3. Lockout power in OFF position.

4. Put key in pocket.

5. Clear machine of all personnel.

6. Test lockout by hitting run button.

7. Block, chain or release stored energy

sources.

8. Clear machine of personnel before restarting

machine.

Note: You will also find this procedure on a decal

affixed on the machine.

When installing the stripper head, insert 4 3/8"

[111mm] of blocking in addition to the 1 1/2"

[38mm] blocks already affixed to the stripper head

frame (figure 4.16). The above blocking assumes a

stripper head height of 14 3/16" [360 mm] from the

top of the head plate to the bottom of the shoes.
