    4.             HOW TO ASSESS THE RISKS

A risk assessment involves considering what could happen if someone is exposed to a hazard and the likelihood of it happening.

Regulation 66: A person conducting a business or undertaking must assess health and safety risks associated with the identified hazards of the confined space.
The risk assessment for a confined space must be undertaken by a competent person and be recorded in writing. The risk assessment must be reviewed and revised whenever any risks change.
Regulation 77: A copy must be kept for 28 days, or if a notifiable incident occurs in connection with the work to which the assessment relates, for 2 years after the incident occurs.
When undertaking a risk assessment to determine the risks requiring control the following factors should be considered:
    * the atmosphere in the confined space, including whether testing or monitoring is to be undertaken
    * the risk of engulfment of a person
    * all proposed work activities, particularly those that may cause a change to the conditions in the confined space.
    * the number of persons occupying the space
    * the soundness and security of the overall structure and the need for lighting and visibility
    * the identity and nature of the substances last contained in the confined space
    * any risk control measures needed to bring the confined space to atmospheric pressure
    * the number of persons required outside the space:
          + to maintain equipment essential for the task being undertaken within the confined space
          + to provide continuous communication with the persons within the confined space, and
          + to properly initiate emergency response procedures
    * risks associated with other hazards, such as noise or electricity
    * arrangements for emergency response, for example first aid and resuscitation
    * the physiological and psychological demands of the task and the competency of persons involved in the tasks or emergency response duties
    * the adequate instruction of persons in any required procedure, particularly those that are unusual or non-typical, including the use and limitations of any personal protective equipment and other equipment to be used
    * the availability and adequacy of appropriate personal protective equipment and emergency equipment for all persons likely to enter the confined space.
    * the need for additional risk control measures, including:
          + prohibiting hot work in adjacent areas
          + prohibiting smoking and naked flames within the confined space and adjacent areas
          + avoiding contamination of breathing air from operations or sources outside the confined space, for example, from the exhaust of an internal combustion engine
