and self-contained breathing apparatus. The appropriate respiratory protective equipment should be based on the level and type of contaminants and the work to be done. Whenever there is any doubt about the type of respiratory protective equipment required,
a conservative approach should be adopted (for instance, use air-supplied respiratory equipment).
Further guidance is available in AS/NZS 1715: Selection, use and maintenance of respiratory protective devices.

    5.7         Communication and safety monitoring

Regulation 69: The person conducting a business or undertaking must ensure that a system
of work is provided that includes:
    * continuous communication with the worker from outside the confined space
    * monitoring conditions within the confined space by a standby person who is in the vicinity
      of the confined space, and if practicable, observing the work being carried out.
A communication system is needed to enable communication between people inside and outside the confined space and to summon help in an emergency.
Depending on the conditions in the confined space, communication can be achieved by voice, radio, hand signals or other suitable methods.
Before a worker enters a confined space, a standby person must be assigned to continuously monitor the wellbeing of those inside the space, if practicable observe the work being carried out and initiate appropriate emergency procedures when necessary (see Figure 7).
The standby person should:
    * understand the nature of the hazards inside the particular confined space and be able
      to recognise signs and symptoms that workers in the confined space may experience
    * remain outside the confined space and do no other work which may interfere with their primary role of monitoring the workers inside the space
    * have all required rescue equipment (for example, safety harnesses, lifting equipment,
      a lifeline) immediately available
    * have the authority to order workers to exit the space if any hazardous situation arises
    * never enter the space to attempt rescue.

    5.8         Entry and exit procedures
For the entire period the confined space entry permit is valid, procedures should be in place to indicate when any worker is in the space, for example by using tags, a system of signing in and out on the entry permit, or having a standby person record who is in the space.

    5.9         Signs and barricades
Before any work in relation to a confined space starts, signs must be erected to prevent entry of persons not involved in the work.
Signs must warn against entry by people other than those who are listed on the confined space entry permit, and must be placed at each entrance to the confined space. Signs must be in place while the confined
