Safety Alert

The EWPA has also discussed the incident with the MEWP manufacturer LG Travel Tower Services, who has confirmed they are providing assistance to WorkSafe WA on the investigation. LGTTS sent out a field bulletin directly to the owners of model GP14-300 requiring an inspection to verify the safe working condition of the machine.

A copy of the Field Bulletin from LGTTS can be found on the Safety Alerts and Notices page on the EWPA website.

This incident and Safety Alert highlights that the safe use of an MEWP requires a rigorous and documented inspection regime. Any technician who inspects or services an MEWP must be competent. For insulated MEWPs the technician must be competent with regard to composites and use appropriate inspection methods. The Safety Alert lists required inspection practices to address this potential failure.

The EWPA offers a Registered Inspector Program, which is an industry-led program that identifies technicians who have competency to inspect MEWPs.  The EWPA recommends the use an EWPA Registered Inspector for safety inspections. You can find a Registered Inspector on the EWPA website
