A confined space entry permit should include questions and information that ensure regulatory compliance and hazard control. Key elements to include are:

• The length of time the permit is valid for.
• The name(s) of the worker(s) that are authorized to enter the confined space.
• The name(s) of the attendant(s) (safety watch).
• The name of the supervisor responsible for the work.
• The location and description of the confined space.
• The scope of the work that is to be done in the confined space.
• Possible hazards that may be encountered inside and outside the space.
• Possible hazards that may develop during the work activity.
• The date and time of entry into the confined space and the anticipated time of exit.
• The details of any atmospheric testing done of the confined space - when, where, results, and date monitoring equipment was last calibrated. Ideally, calibration (including bump test) would be done just before each use. If this is not possible, follow the equipment manufacturer's guidelines for the frequency of calibration.
• Hazard control measures, including the use of mechanical ventilation, work procedures, personal protective equipment needed and any other precautions that must be followed by every worker who is going to enter the confined space.
• Means of communication between the persons working in the confined space and the attendant.
• Emergency plan, and the protective equipment and emergency equipment to be used by any person who takes part in a rescue or responds to other emergency situations in the confined space
• A signature of a worker who did the confined space air testing. The signature on the permit would indicate that adequate precautions are being taken to control the anticipated hazards.
• Authorization signature by the supervisor certifying that the space has been properly evaluated, prepared, and it is safe for entry and work.

[1] [2] Additionally, the permit should verify the completion of several key items:

• Control of atmospheric and engulfment hazards.
• Confirmation that operating and rescue procedures are available at the work site.
• A survey of the surrounding area to identify potential hazards such as drifting vapors.
• Atmospheric testing to identify dangerous air contamination and/or oxygen deficiency, including documentation of pre-entry test results.
• Verification of rescue service availability and operable means for summoning them.
• Confirmation that all tests specified by the permit have been conducted.
• Confirmation that all procedures and equipment specified by the permit are in place before entry begins.

[3] [4] [5] [5] The permit must also specify how isolation shall be performed and any other necessary preparations before entry. [7]

For areas where tanks are repeatedly entered, an "Area Entry Permit" can be issued for a period, such as one month, covering production areas where entry and exit are made using manholes. [6]

The entry permit should be posted at the confined space until the work is completed, and the employer should keep a copy on file. [2]
