WorkSafe Victoria is issuing a safety alert highlighting the hazards associated with using small-bore fittings following a number of recent incidents at Major Hazard Facilities (MHF). WorkSafe has recently been notified of three separate incidents involving the loss of containment of highly toxic and corrosive chemicals caused by the use of small-bore fittings for temporary connections. The connections were made using a mixture of imperial and metric-sized components that were NOT COMPATIBLE. One incident resulted in the partial evacuation of an MHF and the need for emergency services to attend. No injuries were reported from these recent incidents.
