Conveyor Fire
COUNTRY OF ORIGIN
WHAT HAPPENED
During repair work by contractors at Central Regions Trentham Quarry in April, hot metal came into contact with flammable material on a screen under-pan igniting the field conveyor. The picture below shows the extent of damage caused. A hot work permit was in place, a hot work checklist had been completed, risk assessments and safe working practices had been prepared. However, the contractor altered their method of work without updating their risk assessment or informing site management. Quick action by site employees and the contractors to isolate electrical and gas cutting equipment prevented a more severe incident.
