Before initiating entry into a confined space, employers must ensure which of the following?

Ensuring that a proper assessment of potential hazards has been performed is critical before entering a confined space because it directly influences the safety and health of workers. Conducting a thorough hazard assessment allows employers to identify any potential risks associated with the specific confined space, such as toxic gases, low oxygen levels, flammable materials, or physical hazards like moving parts or engulfment risks. This evaluation informs the development of appropriate safety measures, including the use of personal protective equipment (PPE), ventilation needs, and emergency response plans, thus significantly reducing the chances of accidents or injuries during the operation.

While having trained employees on emergency procedures, ensuring availability and inspection of safety gear, and training staff on confined space procedures are all important components of a safe confined space program, they are predicated on first understanding what hazards exist in the space. Without this foundational hazard assessment, other safety measures may not be properly targeted or sufficient to address the risks present.
