straight forward health and safty advice
No one should attempt to erect, alter or dismantle a mobile tower until
they have receiving proper training
Attending a PASMA (Prefabricated Aluminium Scaffold Manufactures Association), or equivalent
training course, will provide the required level of training.
Where the work at height assessment indicates that a mobile tower is the best choice, then it
should be provided with double guard rails and have toe boards to minimise the likelihood of a
fall, and should have a ‘built-in’ access ladder, preferably on the inside of the tower.
Each manufacturer has their own specific requirements on how their tower should be built and
dismantled; which must always be done using a safe method of work. There are two approved
methods recommended by the PASMA, which have been
developed in co-operation with the Health and Safety
As a broad guide, the maximum height of a mobile scaffold
should not be more than three times the minimum base width
for outside use, and three and a half times for inside use.
Outriggers or ties must be used when these ratios are
A competent person must inspect the tower, and make a record
of this, when the tower is erected and before it is first used;
and then every seven days if the tower remains in the same
Keep the working platform, free of nonessential materials and
do not use the tower for support purposes at any time. Never
use boxes, steps and so on, to gain extra height from the
working platform – always add an extra lift.
