Prior to entering a permit-required confined space, what should you verify?

a standby person should be located outside the entrance to the confined space, while another person should be within sight or call of the standby person
proper lighting inside the confined space
availability of personal items
emergency exit options

The correct answer is: a standby person should be located outside the entrance to the confined space, while another person should be within sight or call of the standby person

Confined spaces can be extremely dangerous due to limited entry and exit points, air quality concerns, and other hazards. As such, it is crucial to have a standby person positioned outside the entrance to the confined space. This person should not only be able to keep visual contact with the person entering, but also have the ability to quickly call for help if needed. It is also important for another person to be within sight or call of the standby person to further ensure prompt emergency response. While options B, C, and D may seem important, they are not the top priority when it comes to entering a permit-required confined space.
