HSE Safety Alert – Failure of a road tanker pressure / vacuum relief valve
The Health and Safety Executive (HSE) have issued a Safety Alert highlighting a failure of a road tanker pressure / vacuum relief valve
View the safety alert for full details.
Bulk transport containers used for flammable, corrosive and toxic liquids and gases will normally have a pressure/vacuum relief valve fitted to prevent damage to the tank from changes in the internal pressure. These valves should be inspected and maintained in line with the manufacturer's instructions.
Following a road incident in April 2020, investigations by Cleveland Police and HSE found evidence that a pressure/vacuum relief valve had undergone an unauthorised modification by a third party which prevented the valve's safe operation.
