Sewer and Storm Drain Entry
Construction · Ver en español
Talking points
- Sewers and storm drains are some of the most dangerous confined spaces. H₂S from decomposing organic matter can reach lethal levels without warning.
- Rising water from upstream activity, storms, or tidal influence can flood a sewer system rapidly. Monitor weather upstream and coordinate with system operators.
- Long entry and exit distances in sewer tunnels mean rescue takes longer. Plan your rescue method for the maximum distance any worker will travel from the entry point.
- Biological hazards — bacteria, viruses, fungi — are present in sanitary sewers. Wear appropriate PPE (rubber boots, gloves, face protection) and wash thoroughly after exit.
- Multiple manholes along a sewer line mean multiple potential entry points for hazardous atmospheres. Monitor not just your entry point but conditions along the entire working segment.
Ask the crew
If we are entering a sewer or drain today, are we monitoring for H₂S, do we know the weather forecast, and is the rescue plan realistic for the distance involved?
Standards this talk is built on
A toolbox talk is a short safety briefing. It supports the training a standard requires; it does not replace it.
