BS EN 13731-2007 pdf free.Lifting Bag Systems For Fire And Rescue Service Use – Safety And Peformance Requirements.
BS EN 13731 is a type C standard as stated in EN ISO 12100-1.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document.
Where provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard.
Lifting bag systems are used by Fire and Rescue Services principally to facilitate the release of persons trapped following accidents involving vehicles, heavy machinery, collapsed buildings, collapsed trenches, fallen trees and other natural objects. Lifting bag systems are generally used in conjunction with other means to support or stabilise the load being moved, for example, blocks, chocks and props.
When compiling this European Standard, it was assumed that:
a) the manufacturer will design and/or use components in accordance with the usual engineering practise and calculation codes, including all failure modes;
b) only trained and competent persons whilst wearing suitable gloves, will use and operate the machinery;
c) the working place is adequately lit;
d) negotiations occur between the manufacturer and the purchaser concerning particular conditions for the use and places of use for the machinery related to health and safety, which are not within the limits of the scope of this European Standard.
This European Standard specifies requirements for lifting bag systems, where intended operation is inflation by compressed air and used primarily by fire and rescue services.
BS EN 13731 applies to liftng bag systems including some or all of the following components:
hose assemblies and couplings; regulators;
control devices;
— pressure indicators;
— safety valves; lifting bags.
BS EN 13731 applies to lifting bag systems intended for operation under ambient temperatures between -20 °C and 55 °C.
This European Standard deals with all significant hazards, hazardous situations and events during the commissioning, operation and maintenance arising from a lifting bag system when it is used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
