Be Careful in Confined Spaces Working in a confined space is dangerous because of the risks of asphyxiation from noxious fumes or dust, reduced oxygen levels, as well as fire and flood dangers. Where can you find confined spaces? Here are a few examples: water and sewer pipes, silos, utility tunnels, pumping stations, tanks, vats, pits, kilns, wastewater wet wells, sumps, vaults, storage bins, crawl spaces under floors, manholes, meter vaults, water reservoirs, boilers, tunnels, and grit chambers. What you need to do in order to ensure a safe work environment in confined spaces:
- To prevent injuries and deaths, inspect your worksites for confined spaces;
- Use a detailed checklist to analyze the layout, dimensions, entry and exit challenges;
- Get the equipment to test and continuously monitor the atmosphere in each confined space;
- Secure and label each space as a confined space or permit-required confined space;
- Train your employees on all procedures, hazard control, and rescue operations;
- Develop a rescue plan.
- Non-entry rescue is performed with the help of a rope or a winch without entering into the confined space.
- Entry by a trained rescue team: a lot of companies have their own teams trained in the techniques and the equipment to perform rescues.
- Entry by emergency services, such as the Fire Department, to do rescue.
