1 PURPOSE

The Purpose of this Guideline is assist WMC operations in complying with the requirement for a fire protection management plan as detailed in the WMC EHS Management System Standard, Crisis and Emergency Preparedness (WMC-EHS-STD-006).

2 GENERAL

This Guideline provides a summarised description of the relevant testing, inspection and maintenance requirements for fire protection systems. The requirements have been compiled from relevant Australian Standards (AS) and National Fire Protection Association (NFPA) standards. These standards include requirements for the following:

Fire pumps

Monitors and hydrants

Deluge systems

Foam systems; and

Fire ring mains.

The testing intervals described in the tables in the following sections are based on the maintenance requirements of the various systems.

Requirements for small fire protection items such as fire blankets and fire extinguishers have not been addressed in this guideline.

It should be noted that often standards specify prescriptive requirements to address a particular item. These may not necessarily be practical in given circumstances or may be superseded by advances in design. In cases such as these, the main focus is on meeting the performance requirement or desired outcome of the standard.

The standards often provide guidance or suggest alternative testing or inspection methods for different or unusual designs. In the event that a particular task cannot be completed due to design or other external factors, then the referenced standard should be reviewed before contemplating a solution.

The inspection, testing and maintenance routines have been sorted into different frequency intervals. The following frequency intervals are used:

Weekly

Monthly

Quarterly

Annual; and

Two yearly or greater.



The testing requirements are further split from the above headings into subsections. These subsections are divided into tables for the following systems:

Hydrants and Monitors

Fire Pumps

Foam Systems

Deluge Systems; and

Ring Mains.

3 TESTING REQUIREMENTS

Each operation should review the following tables and identify the requirements that are applicable to their fire protection systems.

Certain requirements listed in the tables in this guideline may not be relevant to a particular sites fire protection system. In this event they may be disregarded however a note made to substantiate this decision.

Once requirements have been identified and agreed upon the specific testing and inspection requirements should be entered into the WMC SAP maintenance module.

The record in SAP should contain the actual test required, the piece of equipment for which it is intended, the level of performance required and the organisational position that has responsibility for performing the test or inspection.

Completed inspections and tests should be entered into SAP together with any maintenance performed on the fire protection equipment.

NOTE: A procedure or similar document, stipulating who needs to be contacted and what additional precautions need to be taken prior to any inspection, testing, or maintaining of fire protection equipment is performed should be available and communicated to responsible personnel.

4 WEEKLY TESTING

Weekly tasks that are required for the pump and deluge systems are listed in Table 3.1 and Table 3.2 respectively.

5 MONTHLY TESTING

Monthly tasks that are required for the pump systems, deluge systems, foam systems and hydrant and monitors systems are listed in Table 4.1, Table 4.2 and Table 4.3 respectively.



6 QUARTERLY TESTING

Quarterly tasks that are required for the pump system, deluge system, hydrants and monitors, foam system, and ring main are listed in Table 5.1, Table 5.2, Table 5.3 and Table 5.4. It is also worth noting that certain subtasks listed at the end of the Pump System Table (Table 5.1) and the Deluge System Table (Table 5.2) only need to be performed semi-annually.

7 ANNUAL TESTING

Annual tasks that are required for the pump system, deluge system, hydrants and monitors, foam system and ring main are listed in Table 6.1, Table 6.2, Table 6.3, Table 6.4 and Table 6.5 respectively.
