The concentration of oxygen or airborne contaminants
The level of oxygen and airborne contaminants is a significant contributor to the risk of working in a confined space, therefore:
    * the level of oxygen should be maintained at a safe level and any airborne contaminants in the space are minimised by ventilating prior to and/or during entry
    * any changes that may occur to oxygen or airborne contaminants are determined by testing the atmosphere
    * where the atmospheric conditions cannot be maintained at a safe level, appropriate respiratory protective equipment must be provided.

The work and work method
Consideration should be given to whether the proposed work or work process will introduce any new hazards or contribute to the risks of working in the confined space. Ignition sources must not be introduced into a space that contains a flammable atmosphere.
Work processes should:
    * minimise the release of harmful airborne contaminants into the space
    * reduce the time spent in the space or the number of people that have to enter the space
    * eliminate the risk of engulfment.
Consider any risks associated with the use of personal protective equipment (PPE) in a confined space. Using PPE may introduce new risks for those working in the space, for example the weight or discomfort of protective clothing and hearing protection.

Emergency procedures
When things go wrong in a confined space, people may be exposed to serious and immediate danger. Effective arrangements for raising the alarm and carrying out rescue operations in an emergency are essential (refer to Chapter 6 of this Code).

    5.4         Entry permits
A confined space entry permit provides a formal check to ensure all elements of a safe system of work are in place before people are allowed to enter the confined space. It also provides a means of communication between site management, supervisors and those carrying out the work and ensures that the person conducting the business or undertaking has checked and authorised the entry to the confined space and it is safe to proceed.

Regulation 67: A person conducting a business or undertaking must not allow or direct a worker to enter a confined space to carry out work unless the person has issued a confined space entry permit for the work.
The permit must be completed in writing by a competent person and:
    * specify the confined space to which the permit relates
    * record the names of persons permitted to enter the confined space and the period of time that the work will be carried out
    * set out risk control measures based on the risk assessment, and
    * contain space for an acknowledgement that work in the confined space has
