SAFETY HAZARDS

Where?

At the controls: starting or stopping, set-up, adjusting.

Where you feed materials into the machine: loading, cleaning.

Where the machine cuts, turns, drills, shapes, punches, or moves in any way: cleaning

and maintenance, trouble shooting and repair, adjusting, set up.

At the gears, wheels, cylinders, belts, rollers, chains, cables, sprockets, cams: cleaning

and maintenance, trouble shooting and repair, adjusting, setting up.

Around lift trucks and moving equipment.

Around conveyors, elevators, and cranes.

Around any machinery and equipment that can release energy on you.

ROTATING MOTION

Hazard

Machinery grips and moves clothing, hair and body parts into danger area.

Danger increases when projections are present (screws, bolts, nicks, abrasions, etc.)

10/20

TRANSVERSE MOTION

Movement in a straight, continuous line around a rotating component


11/20

RECIPROCATING MOTION

Back and forth / up and down

Hazard

Caught between the moving part and stationary object


12/20

BENDING ACTIONS

Power applied to slide, to draw, or

stamp metal or other materials in a

bending motion.

Hazard The hazard occurs at the point of

operation where the employee typically

inserts, holds, or withdraws the stock by

hand.


13/20

PUNCHING ACTIONS

Power applied to slide ram for

purpose of blanking, drawing

or stamping.

Hazard The hazard occurs at the point

of operation where the

employee typically inserts, holds,

or withdraws the stock by hand.

SLIDE RAM

MATERIAL


14/20

SHEARING ACTIONS

Apply power to slide or knife to trim or cut


15/20

CUTTING ACTIONS

Rotating, reciprocating or

transverse motion

Examples: Band saw, circular

saw, lathes,drills


16/20

MOTIONS AND THEIR ACTIONS

These motions have different actions and can therefore result in one or

several types of injury

MOTION ACTION TYPE OF INJURY

Rotating Cutting / Trapping Laceration / Amputation

Transverse Impact / Struck by Fracture / Amputation

Reciprocating Entanglement / Pulled by Sprain / Strain Fracture / Amputation


17/20

CONTACT WITH ELECTRICITY, FIRE, HEAT,

COLD, AND OTHER ENERGIES

Where?

At power panels, electrical circuits, power lines, ovens, and heating elements

Around chemical containers, vats, pipes, pumps, and compressors

Around cranes, hoists, other lifting devices

During service and repair jobs

What can happen?

Electrocution

Burn and freeze injuries

Explosions

Uncontrolled gravitational or mechanical energies


18/20

CONTACT WITH PRESSURIZED GAS OR LIQUID

Where?

Nozzles of pressurized cleaning and painting spray lines, air jets

Around injectors, autoclaves, extrudes, chemical containers, vats, pipes, pumps and

compressors

During cleaning, service, and repair jobs

What can happen?

Puncture or cut skin

Damage eyes

Injection of harmful chemicals or bacteria


19/20

CONTACT WITH HARMFUL CHEMICALS

Where?

At or near production and paint jobs, welding, soldering, cutting, boring, grinding,

tapping, reaming, lapping, drilling, broaching

Machine lubricants, degreasers, coolants, protectants, releasing agents, paint, fuel,

cleaners

At plating jobs, vats, tanks

During service and repair jobs

What can happen?

Harmful chemicals can potentially burn, explode, corrode, poison or irritate.


20/20

CONTACT WITH HARMFUL NOISE,

RADIATION, AND VIBRATION

Where?

At stamping, sawing, grinding, polishing jobs

At welding, cutting jobs

At finishing, curing jobs

What can happen?

Some equipment can release harmful noise or radiation that can destroy your

hearing, blind you, burn, or damage your internal organs

Some equipment vibrations can injure soft body tissues, joints
