shall be allowed in the lifting operation area.

2.18 Safety measures shall be taken to address any potential hazards and / or danger that may arise out

of the lifting operation.

2.19 Weather forecasts shall be monitored before and during lifting work. No lifting shall beperformed during abnormal conditions like wind speed is too high, poor lighting, obscured view

due to raining, etc.

2.20 The operator shall be able to observe the load continually during lifting.

2.21 The loads shall be raised vertically to avoid swinging during lifting.

2.22 Whenever required the load shall be controlled by means of tag lines to prevent the load fromturning or swinging.

2.23 Hoisting or lowering loose materials such as small brackets, cut pipes, etc, shall be done in

covered containers or receptacles, and to be secured firmly.

2.24 Only competent, trained and authorised person shall perform lifting and crane operation, rigging

and signaling.

other clearly identifiable clothing.

2.26 Signals shall be specified. Two-way communications shall be arranged whenever required.

2.27 Only authorised signalersshall be allowed to give signals and signs to the crane operator.

2.28 All lifting gear must be identifiable and checked before and after use.

2.29 When a load is suspended at two or more points with slings, the eyes of the lifting legs or the

slings shall be shackled together and placed on the hook or shackled directly to the hoistinghook.

2.30 Hoisting of personnel to height by crane is strictly prohibited, unless otherwise approval is given

in writing by The Commissioner for Workplace Safety and Health (Ministry of Manpower).

2.31 No crane shall operate in such a position and / or location that any part of the crane, its load in

any position, the jib boom, or its swing comes within 3 metres of a live power line unless

otherwise the power is de-energised or the crane shall be effectively earthed.

2.32 Underground cables and / or pipelines which are crossing / located under the crane access shall

be adequately protected with mats or steel plates to prevent damages.

2.33 Using plate clamps

2.34.1 Areas of work must be kept clear during operation.2.34.2 Loads must not be lifted a mans height. However tag lines can be used to control lifting.

All lifting clamps are subjected to annual inspections by Ministry of Manpowers (MOM)Approved Examiner.

2. DESCRIPTION

2.1. Safe work practices can minimise, if not eliminate the risk of an accident. This elementcontains well-defined procedures and instructions to carry out specific works, tasks andequipment operations safely.

3. SCOPE OF APPLICATION

3.1. Safe work Practices shall be established for other hazardous work or work processes asand when required. The SWPs serve as a guide. The list of SWP shall include but not

be limited to the following:-

3.1.1. Control of Mechanical Lifting Operations3.1.2. Confined Space and Dangerous Atmospheres3.1.3. Blasting and Painting3.1.4. Ladders3.1.5. Working at Heights3.1.6. Welding and Heating operations3.1.7. Handling and Control of gas cylinders3.1.8. Fabrication3.1.9. Site Radiography3.1.10. Radiation Safety3.1.11. Control of substances hazardous to health
