What should be taught:

How to lift safely

How to avoid unnecessary

Materials Handling Equipment

Employees must betrained in the properuse and limitationsof the equipmentthey operate

This includesknowing how toeffectively useequipment such asforklifts, cranes,and slings

Forklifts

Center the load on the forks and asclose to the mast as possible tominimize the potential for the trucktipping or load falling

Overloading a lift truck makes it hardto control and could make it tip over

Place the load at the lowest positionfor traveling

Dont place extra weight on the rear ofa counterbalanced forklift to allow anoverload


12/44

Operating a Forklift Safely

Keep arms and legs inside the truckHandle only stable loads

Keep speed low - you may have to stop

Be careful when making sharp turnswith a raised load

If a load blocks your view, travel in reverse

No riders, unless theres an approved seat

Dont drive with forks raised

Wear safety belts or other restraint devices

SummaryManually handling materials

When lifting objects, lift with your legs, keep yourback straight, do not twist, and use handling aids

Using cranes, forklifts, and slings to move materials Watch for potential struck by and crushed by

dangers For slings, check their load capacity, inspect them,

and remove them from service when they displaysigns of stress or wear

Also - Keep work areas free from debris and materials Store materials safely to avoid struck by/crushed
