A safety factor of

22、 the order of 3:1 has been used and the mass of a firefighter including personal equipment and breathing apparatus has been taken as 108 kg. The standard sets out minimum and/or maximum values within which the customer may specify his own requirements. In preparing this standard it has been recogniz

23、ed that the operational use of portable ladders varies throughout Europe. BS EN 1147:2010EN 1147:2010 (E) 6 1 Scope This European Standard specifies requirements, test methods and performance criteria for portable ladders for fire and rescue service use and associated purposes.
