It's important to realise that there are inherent risks involved with working with compressed air. Before you begin any work, you need to contact your Operations Manager and get their permission to carry on.

  • Yes, I've spoken to him or her and have full permission to service my fill stations
  • Not yet- I hadn't realised it was important!
