The COP must set out how significant risks are identified and assessed in terms of the risk assessment process referred to in paragraph 7, and how it will be addressed. The COP must cover at least the aspects set out below:
| 8.1. |
Identification and register of confined spaces |
The COP should ensure that:
| 8.1.1. |
Confined spaces are identified by a competent person through the mine’s risk management process and access into the confined space shall be physically restricted using barriers to prevent unauthorised entry whenever possible. |
| 8.1.1.1. |
The risk assessment should cover the following (but not limited to): |
| (a) |
The health and safety risks associated with entering and working in a confined space; |
| (b) |
The reportable accident on fined space; |
| (c) |
The risk assessment must at least consider and record the following information: |
| (i) |
Hazards anticipated to be harmful to employee’s health as well as those to be flammable, explosive and those that require monitoring. |
| (ii) |
Any potential risk of engulfment. |
| (iii) |
How the work itself may change or deteriorate workplace conditions. |
| (iv) |
Ventilation requirements for the duration of work inside the confined space. |
| (v) |
Any other control measures required for entry and work in a confined space. |
| (vi) |
Any other information critical to the health and safety of the employees entering and working in a confined space. |
| 8.1.2. |
All confined spaces are recorded in a register; |
| 8.1.3. |
A confined space risk assessment should be conducted before any work or entry is conducted; |
| 8.1.4. |
A site-specific procedure is developed and implemented to ensure safe confined space entry and work; |
| 8.1.5. |
Appropriate signage shall be posted at each entry point denoting that a permit is required prior to entry. Where signage is impractical other means of communication need to be used; and |
| 8.1.6. |
All employees potentially involved in confined space entry or work are aware of the procedure and the register and are conversant with the contents and requirements thereof. |
| 8.2. |
Appointments, roles and responsibilities |
The COP should ensure that the following is clearly defined:
| 8.2.1.1. |

| 8.2.2.2. |
All other employees involved with confined space work shall be trained of their roles and responsibilities, hazards that they will be exposed too in a confined space and record shall be kept thereof. |
The COP should ensure that:
| 8.3.1. |
No person enters a confined space or work inside a confined space without implementing a confined space procedure in relation to any relevant confined space risks, that render that work safe and without risk to health. |
| 8.3.2. |
While planning activities requiring a potential entry in a confined space, alternative and safer methods shall always be considered. Whenever management discretion exists, the key principles guiding the application of the hierarchy of control shall be used to scrutinize the risk assessment process and explore all alternatives to avoid the need of having personnel enter confined spaces.
|
| 8.3.3. |
The hierarchy of control is applied when considering the control of confined space hazards, first considering elimination, engineering controls and administrative controls before resorting to personal protective equipment. |
| 8.3.4. |
In managing risks associated with a confined space, all relevant matters must be considered, including: |
| 8.3.4.1. |
Whether the work can be carried out without the need to enter the confined space; |
| 8.3.4.2. |
The nature of a confined space; |
| 8.3.4.3. |

| 8.5.3. |
confined spaces surfaces are cleared prior to entry to remove materials that may fall on, or create a harmful atmosphere for personnel; and |
| 8.5.4. |
Only intrinsically safe equipment is used inside confined spaces where flammable or potentially explosive atmospheres are likely. In certain confined spaces (e.g. inside metal tanks) suitable precautions to prevent electric shock must include the use of extra low voltage equipment (typically less than 25 V) and, where necessary, residual current devices. |
The COP should ensure that:
| 8.6.1. |
The atmosphere inside a confined space is safe and without risk to health as far as reasonable practicable before entry into and work inside a confined space is allowed. |
| 8.6.2. |
Measures are implemented to ensure that a health and safe atmosphere is maintained throughout the entire period of confined space work. |
| 8.6.3. |
The concentration of any harmful hazard/s identified in the atmosphere of the confined space is less than 5% of its lower explosive limit (LEL), so far as is reasonably practicable. If it is not reasonably practicable, and the concentration of any harmful hazard/s identified in the atmosphere of the confined space: |
| (a) |
Is equal to or greater than 5% but less than 10% of its LEL—the employer must ensure that any worker is immediately removed from the space unless a suitably calibrated, continuous-monitoring flammable gas detector is used in the confined space; or |
| (b) |
Is equal to or greater than 10% of its LEL—the employer must ensure that any worker is immediately removed from the confined space. |
| 8.6.4. |
Where a flammable atmosphere may exist in a confined space and there is a risk of fire and explosion, all ignition sources in the vicinity must be controlled. |
| 8.7. |
Atmosphere testing and monitoring |
The COP should ensure that:
| 8.7.1. |
The atmosphere inside a confined space is tested prior to entering for relevant harmful,flammable substances and oxygen content.

| 8.7.2. |
Atmospheric monitoring is conducted by a competent person. |
| 8.7.3. |
Monitoring requirements, e.g. frequency, are detailed on the confined space entry permit. |
| 8.7.4. |
Atmospheric monitoring results are recorded on the confined space entry permit and be available at the entry point to the confined space. |
| 8.7.5. |
If atmospheric monitoring cannot confirm a safe environment prior to entry, then personnel must not enter the confined space until further controls are implemented and the working atmosphere becoming safe for entry and work. |
| 8.7.6. |
Atmospheric testing equipment have a current and valid calibration certificate. A bump test should be conducted before each day’s use in accordance with the manufacturer’s instructions. |
| 8.8.1. |
The COP should ensure that where the risk assessment has identified the need for ventilation, then this must be covered by a documented procedure approved by a 12.1 Appointee. |
| 8.8.2. |
If the maintenance of a safe oxygen level in a confined space is dependent on mechanical ventilation, equipment shall: |
| (a) |
Be continuously monitored while the confined space is occupied; and |
| (b) |
Have the control (include remote power supply) clearly identified, tagged and manned to guard against unauthorised interference. |
