is being done in the space, e.g. ventilation, continuous monitoring, respiratory protective equipment and personal protective equipment.
                                                     * List any equipment to be taken into the confined space, including any exclusions such as ignition sources.
                                                     * List any specialist emergency rescue equipment required.

The entry permit must be used as a written record that all workers have exited the confined space on completion of the work. It should be displayed in a prominent place to facilitate signing and clearance. Each worker must be able to understand the entry permit.
The information on the entry permit may be used as a suitable record of the risk assessment that has been carried out. An example of an entry permit is provided at Appendix B.

    5.5         Isolation
All potentially hazardous services should be isolated prior to any person entering the confined space.

Isolate to prevent:
    * the introduction of contaminants or conditions through piping, ducts, vents, drains, conveyors, service pipes and fire protection equipment
    * the activation or energising of machinery in the confined space
    * the activation of plant or services outside the confined space that could adversely affect the space (for example heating or refrigerating methods)
    * the release of any stored or potential energy in plant
    * the inadvertent use of electrical equipment.
If liquids, gases or vapours could enter the confined space the pipe work should be physically isolated.

Isolation measures, for example physically locking, tagging, closing and blanking (see Figure 3) should be supervised or checked at each isolation point. Isolation measures should be supported by systems to ensure that the isolation measures are not removed until all work is complete and all workers have left the space.

Figure 3 Example of tag and lockout with the padlocks of two workers.
Methods of isolation from materials, contaminants or conditions include isolating in accordance with one of the methods described below or by an alternative method ensuring at least an equivalent level of safety:
    * Removing a valve, spool piece or expansion joint in piping leading to the confined space (as close as practicable to the space) and blanking or capping the open end of the piping (see Figure 4). The blank or cap should be tagged to indicate its purpose. Blanks or caps should be made of a material that is compatible with the liquid, vapour or gas with which they are in contact. The material should also have sufficient strength to withstand the maximum operating pressure, for example surges, which can build up in the piping.

    * Inserting a suitable full-pressure spade or blank in piping between the flanges as close as practicable to
