Introduction
There are several significant hazards associated with the specification of this equipment. It is important that the designer identify these and assess the associated risks.
Possible hazards and risks
- falls from height, into pits or shafts or whilst accessing equipment at height, whilst installing, commissioning or maintaining equipment
- manual handling: much equipment is bulky and heavy and requires manoeuvering in confined spaces
- confined spaces: such as pits, motor rooms etc
- hazardous substances: dusts and vapours, bottled gases, hydraulic oils etc
- noise and vibration: during commissioning and maintenance
- accidental operation of lift controls during installation, commissioning, repair or maintenance
Some design considerations
- provide sufficient working space for installation and maintenance
- consider access routes during installation and maintenance
- where possible specify compact equipment for ease of handling
- consider installation of permanent lifting equipment for installation and future maintenance and repair
- provide for the installation of safety harness attachments when work at height is unavoidable such as work in lift shafts
- allow for access for delivery and handling of components to installation position
- ensure insulation, isolation, overload protection and earthing is provided for equipment
- ensure car top controls in lifts are positioned to prevent accidental operation
