guard/deflector as
trained
Burst Wheels 10%:

Safe Electrical Safety Practices
Control Measures
Guarding is provided
to contain fragments of the wheel that might fly off if it did burst so
preventing injury to the user and others in the workplace.
The guards secondary
use is deflection of the debris and sparks away from the operator.
Operators suitably
trained in the correct handling and mounting of abrasive wheels (This is for
portable grinders only)
Correct mounting
will reduce the risk of bursting.
Use the double insulated body machines only.
Abrasive Wheel Use
To prevent cracking:
Fit the wheel freely
on the spindle.
Tighten the spindle
nut enough to hold the wheel in place without distorting the flange with spanner.
Let the tool come up
to speed prior to grinding or cutting.
Don’t stand in front
of the wheel as it comes up to full speed.
Use eye and/or face protection.
Ensure to do the pre inspection of machine, wheel and all the Personal Protective Equipment's.
How to Manage Workplace Stress
Power Tools - Precautions

Secure work with
clamps or a vise, freeing both hands to operate the tool.
Don’t hold the
switch button while carrying a plugged-in tool.
Keep tools sharp and
clean.
Remove damaged electric tools & tag them: “Do Not Use”.
Remember User Inspections
Portable Handheld Grinders
Inspect grinder
housing to ensure no cracking/breakage.
Ensure that the
cable is free from cracking/burning/broken sheath and that the plug is in good condition.
Must be 110 volts
& Pat Tested
Discs inspected and
in good condition (correct disc speed for grinder)
Second Handle fitted.
No exposed wires or
lacerations on the cable
