This code specifies the safety requirements for the design, manufacture, erection, operation, and maintenance of temporary access equipment, including suspended scaffolds and mast climbing work platforms (MCWPs). It provides guidelines on materials, stability, factors of safety, and operational procedures to ensure the safety of personnel working at height during construction, maintenance, or inspection activities.
Lays down safety requirements for the design, construction, installation, and operation of temporary access equipment.
Quick Reference Values
Minimum factor of safety for suspension wire ropes10
Minimum factor of safety for structural members (against yield)1.65
Maximum operational wind speed (if unspecified by mfg)12.5 m/s
Static overload test load125% of SWL
Dynamic overload test load110% of SWL
Maximum horizontal gap between platform and building face300 mm
Practical Notes
The role of a 'competent person' is central to this code for design, erection, inspection, and certification. All stages must be properly documented.
Wind is a critical factor. Work must be stopped, and the platform secured when wind speeds exceed the manufacturer's limit or 12.5 m/s (~45 km/h).
Strict adherence to inspection schedules (daily by user, weekly by supervisor, and thorough examination every 6 months by a competent person) is crucial for preventing equipment failure.
