What is WSH Guideline
This set of guidelines aims to provide information and guidance to meet the requirements of relevant legislation and Code(s) of Practice in all workplaces where maintenance of permanently installed electric passenger and goods lift is required. It serves to equip stakeholders in the lift industry with useful practical knowledge and good practices on service and maintenance of such lifts in Singapore.
In general, there are two types of maintenance work:
• Routine maintenance (include but not limited to):
- Lubrication;
- Cleaning;
- Inspection; or
- Adjustments/alignments.
• Non-routine maintenance:
- Troubleshooting and doing emergency repairs;
- Replacing worn or damage components (e.g. cables, ropes, parts of elevator doors, and machine bearings that do not
affect the characteristics of the installation);
- Re-calibrating of load cell and re-adjustment of sensors and switches;
- Job that requires special tools (e.g. cutting equipment, rigging equipment and heat generating equipment);
- Assisting in or performing rescue operations; and
- Replacement of major components such as the machine, the car, the control panel, and so on.
The following operations are considered as non-lift-related-maintenance work:
• Cleaning the external part of the hoist way;
• Cleaning the interior of lift car;
• Rescue operations carried out by the authorities (e.g. Singapore Civil Defence Force).For additional information on periodic maintenance and examination, refer to prevailing Singapore Standard, SS550: Code of Practice: Installation, operation and maintenance of electric passenger and goods lifts.
