22、 accidents encountered when using ladders and are the basis on which the information in this standard 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

23、(such as bottom of the ladders 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 uns

24、table 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) transferrin

25、g 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 time, sliding down stiles). d) Structural failur

26、e of ladder: 1) condition of the ladder (such as damaged stiles, wear); 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 eq

27、uipment (such as covers or protective insulation); 4) incorrect selection of type of ladder for electrical work. BS EN 131-3:2007EN 131-3:2007 (E) 6 6 Marking 6.1 Leaning ladders 6.1.1 Pictograms The basic information that shall be included, as an easily viewed pictogram, marked on all ladders that

28、are designed to be used as leaning ladders is: a) read the instructions (example Figure A.1); b) maximum load (example Figure A.2); c) correct angle of erection (example Figure A.3); d) erect on a level base (example Figure A.4); e) do not over-reach (example Figure A.5); f) ensure ground is free fr

29、om contaminants (example Figure A.6); g) erect on a firm base (example Figure A.7); h) ladder extension above landing point (example Figure A.8); i) do not step off the side of a ladder (example Figure A.9); j) use the ladder the correct way up only if necessary due to design of ladder (example Figu

30、re A.22). 6.1.2 Correct angle indicator Each ladder designed to be used as a leaning ladder should have an indicator to show when it is erected at the correct angle. 6.2 Standing ladders The basic information that shall be included, as an easily viewed pictogram, marked on all ladders that are desig

31、ned to be used as standing ladders is: a) read the instructions (example Figure A.1); b) maximum load (example Figure A.2); c) erect on a level base (example Figure A.4); d) fully opened before use (example Figure A.17); e) do not overreach (example Figure A.5); f) erect on a firm base (example Figu

32、re A.7); g) do not step off the side of a ladder (example Figure A.9); h) ensure restraint devices are engaged if fitted (example Figure A.21). BS EN 131-3:2007EN 131-3:2007 (E) 7 6.3 Useable rungs or treads Each ladder designed to be used as a leaning ladder shall be marked to indicate that the top

33、 three rungs shall not be used for standing on. NOTE 1 The marking may be placed on the stile of the ladder or preferably on the first rung or tread not to be used for standing on. Each ladder designed to be used as a standing ladder shall be marked to indicate the rungs or treads that shall not be

34、used for standing on. NOTE 2 EU Directive 2001/45/EC requires that a secure handhold and secure support is available to the user at all times. 6.4 Other marking information for all ladders Each pictogram shall be a minimum size of 15 mm 15 mm and be of contrasting colour.
