Briefly suspended entry gear (TSAE) aid or include employees operating at top on engineering and building websites. BS 5974 supplies tips and proposals on fitting (erecting, changing and dismantling), preserving, studying and utilizing TSAE in a secure demeanour. It additionally units out the tasks of all employees concerned about operating with TSAE.

BS 5974 makes strategies for the choice, layout, set up, inspection, use and upkeep of quickly put in suspended entry equipment/systems (TSAE), as outlined in BS EN 1808. Non-standard installations also are coated by way of this code.

TSAE could be a operating platform or systems, paintings cage or chair suspended from a suspension rig which might be assembled on the workplace, used to hold out particular projects. TSAE will then be dismantled and faraway from where of labor whilst the categorical projects are entire for use elsewhere.

The gear mentioned in BS 5974 is usually suspended from metal cord ropes which are hooked up to the outriggers of a suspension rig or different compatible high-level anchor element. it's in a position to being raised or decreased via a winch or mountain climbing machine that may be connected both to the operating platform(s), paintings cage or chair or be integrated into the suspension rig. The lifting equipment or home equipment could be manually or strength operated. In sure circumstances, the TSAE will be integrated right into a process that permits it to be traversed horizontally.

Steeplejacks and steeplejack operations should not lined in BS 5974. It additionally doesn't conceal completely put in suspended entry gear, that gear is roofed by way of BS 6037-1.

Requirements for slung scaffolds, being operating systems on scaffold tubes or twine ropes yet which can't be raised or decreased via the person, are contained in BS EN 12811-1.

This model of BS 5974 is a whole revision of the normal, and introduces alterations a result of following:

• alterations in laws, particularly the advent of the Lifting Operations and Lifting apparatus rules (LOLER) 1998
• Advances in technology.

This model of BS 5974 replaces BS 5974:1990, that is now withdrawn.

Sample text

All TSAE systems should be erected to either standard design solutions or to drawings prepared specifically for the system being erected by a competent design engineer. All anchoring forces/counterweights and the permitted RL of the TSAE should be indicated on the drawings together with the expected loads imposed on the building/structure. In all cases, the WLL of the winch/climbing device should be used to calculate the overturning moment and the magnitude of the counterweight or the strength of the mechanical anchorage required.

These subclauses describe the means of ensuring stability. Annex A shows the worked example of a stability calculation. Where counterweights are used to provide stability or when any mass of the structure is relied upon to contribute to the stability, the counterweights or mass should be firmly attached to the suspension rig in such a manner that they cannot become accidentally dislodged. At sites where unauthorized interference might occur, additional special precautions should be taken to ensure that the weights are secure.

All materials should be removed from the TSAE prior to an aerial transfer being carried out and no other person should be allowed on the TSAE during the operations other than the installers actually carrying out the work. The area under the TSAE and its new working position should be protected by appropriate signing and barriers to prevent unintentional access. The repositioning should be carried out using the platform’s secondary safety system as a positive anchor. All operatives should be harnessed to structurally sound independent anchor points when carrying out an aerial transfer.
