A worker sustained thermal burns when they opened a steam ventilation valve located below a ventilation discharge pipe. Water trapped in the vent piping had been heated inadvertently. When the worker opened the valve, the released hot water landed on their back and right shoulder.
Actions
- The area was isolated, and the steam system was secured.
- The injured worker was transported to a hospital, where they were treated and monitored.
- The incident was investigated to determine contributing factors and system deficiencies.
Takeaways
- Configure steam venting and release systems so workers aren’t exposed to potential discharges when opening or closing valves.
- Incorporate guarding, shields or remote operation options in systems to prevent burns and other injuries from unexpected steam or hot water discharges.
- Train workers to recognise residual heat hazards and follow safe operating procedures before manipulating valves.
Summary
Steam and thermal systems can present high-consequence hazards, even during routine operations. Safe system design, including effective isolation and protective measures, is essential to prevent burns and other serious injuries. Workers must not encounter exposures to potential steam or hot water releases.
