a) Loss of stability:
The following list of hazards and examples
of their causes, which is not exhaustive, are
common reasons for accidents encountered
when using ladders and are the basis on
which the information in this manual has
been developed:
1) Incorrect positioning of the ladder (such
as incorrect angle for leaning ladder or
not fully opening a standing ladder);
2) slide outwards at the bottom (such as
bottom of the ladder sliding away from
the wall)
3) side slip, falling sideways and top fl ip for
leaning ladders (such as overreaching or
fragile top contact surface);
4) condition of the ladder (such as missing
anti-slip feet);
5) stepping off an unsecured ladder at
height;
6) ground conditions (such as unstable soft
ground, sloping ground, slippery surfaces
or contaminated solid surfaces);
7) adverse weather conditions (such as
windy conditions);
8) collision with the ladder (such as vehicle
or door);
9) incorrect choice of ladder (such as too
short, unsuitable task).
b) From handling:
1) Transferring the ladder to the work
position;
2) erecting and dismantling the ladder;
3) carrying items up the ladder.
c) Slip, trip and fall of user:
1) Inappropriate footwear;
2) contaminated rungs or steps;
3) unsafe user practices (such as climbing 2
rungs at a time, sliding down stiles).
d) Structural failure of ladder:
1) condition of the ladder (such as damaged
stiles);
2) overloading the ladder;
3) Unintended use.
e) Electrical hazards:
1) Unavoidable live working (e. g. fault
fi nding);
2) positioning ladders too close to live
electrical equipment (such as overhead
power lines);
3) ladders damaging electrical equipment
(such as covers or protective insulation);
4) incorrect selection of type of ladder for
electrical work.
