Competence matters: Incorrect installation of batteries on a scissor lift (MEWP)

A member company recently supplied replacement batteries for an ageing Mobile Elevating Work Platform (MEWP) scissor lift at a university site. 

The company also provided a quotation to carry out the installation of the batteries – this was declined as the customer advised they had an in-house person qualified to complete the work.

The following week, the supplier was called back to investigate because the machine was no longer operational and concerns were raised that the batteries supplied may have been faulty.

Findings:

Upon inspection, the suppliers visiting engineer discovered the batteries had been installed incorrectly, with polarity reversed. This could have resulted in serious damage to the machine and, more importantly, posed a significant safety risk to the individual carrying out the work.
