| 摘要： | The HSE warns users of hazardous goods tanks to visually inspect the pressure/ vacuum relief valves fitted to tank containers and road tankers to look for unauthorised modifications. In April 2020, the vacuum relief element of a tank valve became stuck in an open position, allowing an uncontrolled escape of hazardous nitric acid vapour. Although no-one was hurt, the incident led to a road closure. |
