Anytime work is being performed overhead where others may be working or walking below, regardless if work is being performed from a scaffold, platform or ladder. Steps shall be taken to prevent hazards associated with falling objects.

  • Toe boards shall be used on working platforms and scaffolds over 6 feet (1.8m) in height.
  • Materials shall not be allowed to accumulate next to the edge of the work platform without a means to prevent objects from falling into the area below.
  • Access to the lower area shall be restricted to protect workers or pedestrians in the area.
  • Tools and materials shall be secured either through tethering or other means if they may be dropped to the lower level.

Working at height is commonly defined in many countries as falling more than 2m. Why?

For more than 2 metres, it is commonly defined as high level fall in which most injuries are resulted from. However, there is an increasing trend that there has been similar number of injuries from low level falls (i.e. less than 2 metres) and from high level falls. As such, some countries have deleted the “2 metre rule” as the definition of falling at height. Instead, it is newly defined as working at a place from which a person could be injured by falling from it, regardless of whether it is above, at or below ground level without stating the level of fall.

How does safety helmet function?

The main principle of safety helmet is to protect workers against impact by falling objects or struck by swinging object by energy absorption. Upon hitting by an object, the helmet dissipates some of the energy in the following mechanisms:

(i) Stretching of harness inside the helmet;
(ii) Partial damage of outer shell of helmet.

The remaining energy is then evenly spread around the head to reduce the hitting stress on worker’s head.
