The Health & Safety Executive sets out the proper protocols and practices for working on a construction site. Some of you might not have read and memorised every word that the HSE has ever published. For those unlucky few, we have summarised what the HSE says about working at height in construction.
Work at height means work in any place where, if there were no precautions in place, a person could fall a distance liable to cause personal injury. For example, you are working at height if you:
are working on a ladder or a flat roof;
could fall through a fragile surface;
could fall into an opening in a floor or a hole in the ground.
That seems pretty vague. As a rule of thumb, anything over about 2 metres and you need a fall arrest.
The other thing that HSE stress is that you shouldn’t work at height unless absolutely necessary. The below slider explains this process.
Avoid
Can you avoid working at height in the first place? If NO, Go to Prevent
- Do as much work as possible from the ground
Prevent
Can you PREVENT a fall from occurring? If NO, go to minimise
- Using an existing place of work that is already safe, e.g a noN-fragile roof with a permanent perimeter guard rail or, if not - Using work equipment to prevent people from falling
Minimise
Can you Minimise the distance and/or consequences of a fall?
- If the risk of a person falling remains, you must take sufficient measures to minimise the distance and/or consequences of a fall
When do you need Fall Arrest for Precast Concrete Flooring?
Often, our customers’ projects fall firmly in the ‘minimise’ category. This most often comes up with 1st or 2nd floor hollowcore plank installs. Although in some cases, it is necessary to use fall arrest around a lorry.
