• This is a low risk stage of Spon com. OCE and all production supervisors must be notified immediately. Controlling of Spon com in these areas must occur as soon as practicable.

• Gas testing and monitoring by the OCE or delegate is to take place to establish if a risk to personnel is acceptable.

• Supervisors and OCE to develop a safe treatment plan to remediate the spontaneous combustion, as soon as practical mobilise equipment and resources to the area to implement the treatment plan. NOTE: Treatment of spontaneous combustion may depend on the area however in all situations water shall only be used to extinguish flame and only when all other methods have been deemed unsafe or ineffective. Options for treating Spon com in active mining area may include: - Excavate and load out heated material. - Compact loose coal leaving no raised edges to catch wind. (Safety bunds may be left for safety reasons.) - Grade the coal to a hard floor and clean any loose coal from toe of faces.

• Supervisor to assess area for possibility of spontaneous combustion reoccurring specifically looking for loose coal, temperature spikes etc.

• Supervisor to immediately assess the need for individuals to be in the area. Wind direction to be monitored. Supervisors who have teams conducting work in the area will conduct a JHA to identify hazards and controls required for personnel to continue working in area.

• Gas testing and monitoring by the OCE or delegate is to take place to establish if a risk to personnel is acceptable.

• Supervisors and OCE to develop a safe treatment plan to remediate the spontaneous combustion, and immediately mobilise equipment and resources to the area to implement the treatment plan.

• OCE is to detail the Spon com event in the OCE report.

• Any persons showing early warning signs and physical signs of discomfort from the spontaneous combustion is to be removed from the area and taken to the site paramedic.

• Supervisors to put together an amber alert detailing Spon com issue occurring in the pit , it's location and the actions taken to avoid any fume or gas given off from the event. Amber alert to be included in the OCE report email sent for that shift.
