It goes without saying that standing in the bucket of an excavator to hang a sign is not a good or safe idea. Such behavior is not only unsafe but also violates California General Industry Safety Orders, §3657 – Elevating Employees with Lift Trucks (Fed OSHA §1910.67).
- Extendable boom platforms,
- Aerial Ladders,
- Articulating (joined) boom platforms,
- Vertical towers, and
- Combination of the above
The bucket of any excavator does not fit the definition of an aerial lift.
According to OSHA (osha.gov) even if someone properly uses an aerial lift the hazards for using such equipment may include:
- Fall from elevated level,
- Objects falling from lifts,
- Ejections from the lift platform,
- Structural failures (collapses)
- Electric shock (electrocutions),
- Entanglement hazards,
- Contact with objects, and
- Contact with ceilings and other overhead objects
As illustrated in the photo below the gentleman is hanging a warning sign while standing inside the bucket of an excavator. How ironic that someone is hanging a warnign sign considering the unsafe behavior being exhibited.
In the instance of hanging a warning sign a safe practice would be to use a properly designed ladder supported by solid footing. Solid footing in this case would have been a smooth, level, and solid ground.
