All workers are tra<strong>in</strong>ed <strong>in</strong> <strong>the</strong> hazards and <strong>the</strong> safety measures when work<strong>in</strong>g with electricity<br />
In every shift, <strong>the</strong>re is one person tra<strong>in</strong>ed <strong>in</strong> basic life support (such as cardio-pulmonary<br />
resuscitation, CPR) <strong>in</strong> case of an accident with electricity<br />
A.2.3 Mach<strong>in</strong>es and Power Tools<br />
Mach<strong>in</strong>es can hurt people. They need to be constructed correctly to be safe for <strong>the</strong> workers who<br />
handle <strong>the</strong>m or even just pass<strong>in</strong>g by. All too often, a worker is pulled <strong>in</strong>to a mach<strong>in</strong>e such as a<br />
conveyor belt, a gr<strong>in</strong>der or a crusher.<br />
The major mach<strong>in</strong>es <strong>in</strong> a crush<strong>in</strong>g unit are <strong>the</strong> primary and secondary crusher, <strong>the</strong> conveyer belt, and<br />
<strong>the</strong> sorters.<br />
Small 'mach<strong>in</strong>es' such as power tools can also be dangerous if <strong>the</strong>y are not properly ma<strong>in</strong>ta<strong>in</strong>ed and<br />
repaired if broken.<br />

No guards are <strong>in</strong>stalled around <strong>the</strong> crusher’s mov<strong>in</strong>g parts, nip po<strong>in</strong>ts, flywheels, conveyor drives,<br />
etc. to prevent cloth<strong>in</strong>g be<strong>in</strong>g pulled <strong>in</strong>to <strong>the</strong> mach<strong>in</strong>e<br />
No emergency switch for <strong>the</strong> conveyor belt or <strong>the</strong> crushers is <strong>in</strong>stalled to stop <strong>the</strong>m if a worker is<br />
pulled <strong>in</strong>to <strong>the</strong>m<br />
Workers are wear<strong>in</strong>g loose cloth<strong>in</strong>g which can easily be caught and pulled <strong>in</strong>to a mach<strong>in</strong>e<br />
Conveyors are not<br />
periodically <strong>in</strong>spected<br />
and tested<br />
Workers are not<br />
properly tra<strong>in</strong>ed <strong>in</strong> safe<br />
procedures to protect<br />
<strong>the</strong>mselves from mak<strong>in</strong>g<br />

Movable conveyors are<br />
often <strong>in</strong> unstable<br />
positions<br />
No personal protective<br />
equipment (PPE) is<br />
provided to workers (see<br />

especially dur<strong>in</strong>g<br />
