— check that the entire ladder is free from contaminants(e.g. dirt, mud, paint, oil or

grease);

— check that locking catches (if ﬁtted) are not damaged or corroded and function

correctly;

— check that the platform (if ﬁtted) has no missing parts or ﬁxings and is not

damaged or corroded.

If any of the above checks cannot be fully satisﬁed, you should NOT use the ladder.

For special ladder types, further items identiﬁed by the manufacturer shall be taken

into account.

Reasons for accidents

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:

a) Loss of stability:

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 ﬂip (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.

e) Electrical hazards:

1) Unavoidable live working (e. g. fault ﬁnding);

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.
