What is the primary purpose of a confined space entry permit at a landfill?

The primary purpose of a confined space entry permit at a landfill is to ensure the safety of workers entering confined spaces by identifying and controlling hazards associated with the confined space. A confined space is defined as a space that is large enough for a worker to enter and perform assigned work, has limited or restricted means for entry or exit, and is not designed for continuous employee occupancy. Confined spaces at landfills might include tanks, manholes, leachate collection system components, or other enclosed structures. The permit process requires a qualified person to evaluate the confined space for potential hazards, such as oxygen deficiency, toxic gases (e.g., methane, hydrogen sulfide), flammable atmospheres, or engulfment hazards. The permit specifies the necessary precautions and procedures to be followed before and during entry, including atmospheric testing, ventilation, lockout/tagout of equipment, use of personal protective equipment (PPE), and rescue procedures. The permit must be signed by the entry supervisor, attesting that all necessary safety measures have been implemented, and by the entrants, acknowledging the hazards and safety procedures. This comprehensive process helps prevent accidents and ensures that workers can safely enter and exit confined spaces. Without a permit, workers could enter a confined space without being aware of the hazards, leading to serious injury or death.
