Safety and health in construction

5.1.23. Loaded wheelbarrows placed directly on a platform for raising or
lowering should be taped or secured so that they cannot move and the platform should
be enclosed as necessary to prevent the fall of the contents.

5.1.24. In hoisting a barrow, the wheel should not be used as a means of lifting
unless efficient steps are taken to prevent the axle from slipping out of the bearings.

5.1.25. To avoid danger, long objects such as girders should be guided with a tag
line while being raised or lowered.

5.1.26. Landings should be so designed and arranged that workers are not obliged
to lean out into empty space for loading and unloading.

5.1.27. The hoisting of loads at points where there is a regular flow of traffic
should be carried out in an enclosed space, or if this is impracticable (e.g. in the case of
bulky objects), measures should be taken to hold up or divert the traffic for the time
necessary.

5.2. Hoists

5.2.1. Hoist towers should be designed according to national laws and
regulations.

5.2.2. Hoist shafts should be enclosed with rigid panels or other adequate
fencing:
(a) at ground level on all sides;
(b) at all other levels at all points at which access is provided;

(c) at all points at which persons are liable to be struck by any moving part.

5.2.3. The enclosure of hoist shafts, except at approaches, should extend where
practicable at least 2 m above the floor, platform or other place to which access is
provided except where a lesser height is sufficient to prevent any person falling down
the hoistway and there is no risk of any person coming into contact with any moving
part of the hoist, but in no case should the enclosure be less than 1 m in height.

5.2.4. Approaches to hoists should be provided with substantial gates or the like
which:

(a) should be gridded for visibility;

(b) should, where practicable, be at least 2 m high;
(c) when closed prevent access to the hoist platform and any moving part of the hoist.

5.2.5. The guides of hoist platforms should offer sufficient resistance to bending
and, in the case of jamming by a safety catch, to buckling.
