Safeguarding Machinery

PPT-SM-SM 2018

Safeguards are essential for protecting workers from preventable injuries caused by moving machine parts. Any machine part, function, or process that may cause injury must be safeguarded.

Machine guards are barriers that prevent access to the danger area of a machine.

2

PPT-SM-SM 2018

Moving machine parts can cause injuries, such as crushed fingers or hands, amputations, burns, or blindness.

Workers who operate and maintain machinery experience approximately 18,000 amputations, lacerations, crushing injuries, and abrasions, and more than 800 deaths per year.

3

PPT-SM-SM 2018

Amputations are one of the most severe and crippling types of injuries in the occupational workplace, and often result in permanent disability.

Amputations are widespread and involve a variety of activities and equipment.

4

PPT-SM-SM 2018

Amputations often occur when the following equipment is unguarded or inadequately safeguarded:

Mechanical power pressesPower press brakesRoll-forming and roll-bending machinesBand sawsDrill pressesMilling machinesShears, grinders, and slittersTable and portable saws

5

PPT-SM-SM 2018

Your company must protect workers from amputation hazards through adequate guarding and worker training on how to do the job safely.

The best way to prevent amputations caused by stationary or portable machinery is with machine safeguarding.

6

PPT-SM-SM 2018

Safeguards should be secure and strong, and workers should not be able to bypass, remove, or tamper with them.

Safeguards should not obstruct the operator’s view or prevent others from working.

7

PPT-SM-SM 2018

Safeguards must prevent hands, arms, and any other part of a worker's body from making contact with dangerous moving parts.

8

PPT-SM-SM 2018

Machine guards protect workers from:

The point of operationIn-running nip pointsRotating partsFlying chips and sparks

9

PPT-SM-SM 2018

Types of machine guards include:

FixedInterlockedAdjustableSelf-adjusting

10

PPT-SM-SM 2018

Fixed guarding is a permanent part of the machine. They may be constructed of sheet metal, screen, wire cloth, bars, or plastic.

Fixed guards provide a barrier and allow for stock feeding but do not allow the operator to reach the danger area.

11

PPT-SM-SM 2018

Interlocked guards stop the machine before a worker can reach their hand into the danger area.

When an interlocked machine guard is opened or removed, the:Tripping mechanism and/or power automatically shuts off or disengagesMoving parts of the machine are stoppedMachine cannot cycle or be started until the guard is back in place

12

PPT-SM-SM 2018

Adjustable guards are useful because they allow flexibility in accommodating different sizes of stock. They provide a barrier that may be adjusted to work with a variety of production operations.

13

PPT-SM-SM 2018

Self-adjusting guards open and close to admit stock. They provide a barrier that moves according to the size of the stock entering the danger area.

14

PPT-SM-SM 2018

Machine operators should receive specific and detailedtraining in safeguarding against mechanical hazards.

15

PPT-SM-SM 2018

Training should explain:

All hazards in the work area, including machine-specific hazardsSafe work practices and machine operating proceduresThe purpose and proper use of machine safeguardsAll procedures for responding to safeguarding problems

16

PPT-SM-SM 2018

When engineering controls cannot fully protect workers, machine operators must wear personal protective equipment (PPE).

Appropriate PPE may include hard hats, eye protection, hearing protection, protective coveralls, special sleeves and gloves, and protective footwear.

17

PPT-SM-SM 2018

Sometimes PPE can create a hazard, like a protective glove becoming caught between rotating parts or loose clothing becoming entangled in rotating spindles or other kinds of moving equipment.

18

PPT-SM-SM 2018

Workers should not wear loose-fitting clothing or jewelry or other items that could become entangled in machinery.

Long hair should be worn under a cap or otherwise

contained to prevent entanglement in moving machinery.

19

PPT-SM-SM 2018

Safe work practices when working around machinery include:Remove slip, trip, and fall hazards from the areas around machinesUse drip pans when oiling equipmentRemove waste stock as it is generatedMake the work area large enough for machine operation and maintenancePlace machines away from high traffic areas to reduce worker distraction

20

PPT-SM-SM 2018

Machinery can be an amputation hazard to the workers who operate it. Your company must protect workers from amputations.

Machine safeguarding can help protect workers from amputations. Make sure you always have the proper safeguards in place while using machinery.
