Preventing Dropped Objects Incidents
Lifting gear: Ensure it is in good condition
Correct size/rating
Not expired
Brakes are operable. Always check/test before use. Follow maintenance schedule.
Maintain/preserve the lifting gears properly. Improper maintenance will lead to
premature failure.
Ensure correct shackles are use and installed with split pins.
Secure tools when working on elevated platform
Have a proper tool holder/container
Put tarpaulin on top of scaffolding planks or gratings to prevent object slip through and
drop down to the deck below.
Carry out adequate work assessment to determine the best lifting/rigging
procedure.

Preventing Dropped Objects Incidents
Improve house keeping and storage: Do not leave tool or redundant material on elevated platform.
Barricade the area where overhead work took place.
Send tools to where it belong.
Do not mix a good and bad sling.
Do not mix various sizes of shackle in a single bin.
Arrange the storage properly. Do not overload the shelves.
Identify hanging equipment which have corroded bracket/support e.g. lighting,
speaker, gas detector, signage, etc., and raise work order to rectify
Temporary secure with chain/clamp
Ensure equipment used is compatible to work place environment/climate
Include dropped object hazards in TRA

Activity
Objective: To educate personnel on Dropped Objects in and around the workplace
Activity should take about 30 minutes
1. Split into groups and assign to various locations/modules at your work area.
2. Look for the Dropped Object or potential of Dropped Object Incident e.g. hanging
lighting fixture, unsecured materials on elevation, etc.
3. Take immediate action to rectify/eliminate hazards
4. What can you do to prevent recurrence of your findings?
5. Share your findings
6. Raise Hazards Improvement Card on any findings
