2. Hand tools and materials can become drop hazards in four
ways:
• During vigorous use and other factors can cause the user to lose
control of the tool.
• Duringtransportation of tools to or from location of work – collisions,
lack of control and other factors can cause tools to be dropped.
• After use, tools can be unintentionally left behind or placed
aside on the working
surface where they are no longer secured or beingcontrolled.
• Failure of equipment or wear.

3. The following can be used to maintain
An extension made of durable materials that is designed to stop an
object as it drops.
They will typically utilize a connection point on either end of the tether for
securing an object to a worker or stationary item.
These devices are to be considered a Primary Drop Prevention System.

5. • At ground level the operatives should conduct a visual inspection
on all working at height equipment, this includes alltethers.
• The visual inspection is to checkfor:
o Visible damages
o Contamination of substances with potential to affect the
efficiency of the tether.
o Loose connection points.
• If your tethers are damaged or not fit for use, they are not to be used.
Replacements should be put in place before performing workingat
height activity.
