Confined Space Entry: drain cleaning
A confined space is any space that is large enough for an employee to enter, that has a restricted means of entry or exit, and that is not designed for continuous employee occupancy.

Examples of confined spaces include tanks, pits, certain tunnels, utility vaults, and boilers. The physical and atmospheric hazards often associated with confined spaces can cause serious injury or death to workers.

The major factors that lead to injuries in confined spaces include failure to recognize and control these hazards, and inadequate or incorrect emergency response.

ESG staff are specially trained in this area to ensure that all safety measures are met to perform confined space entry.

Below are some examples of areas that ESG specialize in performing C.S.E (confined space entry).


  • Pump Station, GPT and drain cleaning activities


  • Pipe Line and Drainage infrastructure inspections


  • Maintenance and cleaning of tanks


  • Telecommunications and electrical utility work performed in manholes and unvented vaults
