Workplace Health & Safety Queensland has issued an alert following the death of a worker hit by a hose from a 100 tonne pressure vessel.

The worker received severe head injuries while removing the hose.

Initial inquiries indicate the worker was bleeding the vessel when he was struck on the head by the hose, rendering him unconscious. He died of his injuries in hospital.

WHS Qld said investigations are continuing.

"There are many different types of pressure vessels, lines and hoses which can be hazardous. These include boilers, air compressors and receivers, gas storage tanks and associated equipment," the alert said.

"A failure or sudden release of a line or a hose under pressure can be devastating to people nearby.

"Before performing any work on a pressurised system, a risk assessment must be carried out."

The assessment should examine factors such as the type of system and the pressure within the vessel and associated lines and hoses as well as the previous maintenance history of the plant.

The complexity of the system and its controls should also be factored into the assessment.

When working on pressurised hoses for gas or fluid transfer from one vessel to another, ensure they are properly attached to both vessels before valves are opened.

"Ensure valves or controls are properly closed and that the pressure has been bled from the system before hoses or lines are removed," the alert said.

"Make sure the hose and its end fittings are of the correct type and pressure-rating and that they are in good condition."

Since 2012, WHS Qld has been notified of a further 19 events involving workers or bystanders being struck by gas pressure hoses.

"None of these previous incidents resulted in a fatality, but the worker’s death in this instance highlights the potential for another fatality and warrants issuing this alert."
