Within a short span of two days, there were two accidents involving lifting operations, that resulted in the death of one worker and injuring another two.

Case 1
A horizontal lifting clamp was used to lift a web frame. During the lifting operation, the web frame slipped out of the lifting clamp and crushed a worker who was standing next to the web frame.

>> Spreader bar involved in the accident

"Struck by Falling Object" accounted for the second highest number of fatal accidents (26%), after "Falls from Height" (34%) of all fatal industrial accidents from 2002-2005.

All lifting operations must have a lift plan supported by an analysis of the hazards and risks.

Advisory Note(Please note that the following advisory note is provided for the benefit of enhancing workplace safety and health and in no way should the information be misconstrued as implying any liability on any party)

• Selection of the appropriate lifting gears and equipment;
• Assessment of the need for tagline to control movement of suspended load;
• Means of communication during lifting operations;
• Restrictions to the lift operations such as weather and illumination;
• The provision of safe place of work for all personnel during lifting operations.

3. In the lifting plan, there should be a set of written safe work procedures. If the lifting operation deviates from the plan, the lifting operation should stop immediately.
4. The manufacturer or supplier of lifting equipment and gears has a duty to make available to the users, the necessary information on the safe use and maintenance of the lifting equipment and gears.
5. The employer should ensure that the appropriate personnel are adequately instructed, trained and supervised in the use of lifting equipment and gears.
