What happened?
A lighting fixture weighing 18 kg (40 lbs), along with the mounting bracket and support, fell 6 m (20 ft) to the deck below.
Fortunately , nobody was in the vicinity at the time.
As a precaution the area was barricaded and electricity cut off to the light fixture.
-
Why did it happen?
Light fixture support bracket failed due to corrosion.
An earlier site inspection had flagged up the imminent failure of the light fixture and support bracket, which were dangling from the flexible conduit.
A secondary retention mechanism had been installed on the light, and connected to the failed bracket, but was unable to prevent the fall.
-
What did they learn?
Verify secondary retention safety mechanisms are fit for purpose and evaluate tie-off points for robustness.
Confirm that corrosion inspection programme includes inspecting light fixture support mechanisms.
Evaluate condition of other light fixture supports and address gaps.

Ask yourself or your crew
How can something like this happen here?
The secondary retention mechanism was installed in response to an earlier inspection. How do we know that mitigation measures, such as these, are fit for purpose and installed correctly?
If an inspection found similar issues here, what could we do differently?
If you become aware of degraded equipment or fixtures, what should you do?
