HSE Shattered Lives Campaign...

The HSE has recently introduced the Shattered Lives campaign, with the aim of reducing accidents in the workplace. Air conditioning maintenance is featured prominently in this campaign:

Tom was always there when things went wrong. He was called in when one of the air con units stopped working in the office. He thought nothing of getting his hands dirty and fixing it. In a hurry Tom grabbed a chair to reach the air con unit as there were no ladders around. Suddenly Tom fell and hurt himself.

An Air Conditioning system is a prime example of a product whose service, maintenance and cleaning should only be performed by suitably qualified engineers.
