Ignition of coal dust in and around the coal processing plants, predominantly in areas of accumulation e.g. tunnel, bins and train load-out.
Excludes explosions in bins (i.e.. confined space), blasting in bins and blasting in hot/reactive ground,
To ensure the safety of coal mine workers conducting work where there is a risk of fire or explosion from the accumulation of coal dust, typically in coal processing tunnels, bins and train load-out.
Work performed in areas where there is a risk of coal dust ignition manages the risk of potential ignition/spontaneous combustion of coal dust/fines through housekeeping, dust suppression and extraction.
Select 2 active work front/s in and around the Coal Preparation Plant (CPP) (such as tunnels, bins or train load-out) and verify the following;
Does the risk assessment for the task identify the hazard of coal dust ignition and are appropriate controls identified and implemented?
Are housekeeping standards being managed to prevent the accumulation of dust build-up (including hosing of the work area to reduce dust build-up / risk of dust spontaneous combustion)?
Are extraction fans operational prior to entering the tunnel?
Obtain extraction fan maintenance strategy and verify the following:
Are inspection / maintenance regime to schedule and actions completed (sight evidence)?
Electrical Hazardous Areas Audit (EEHA) is conducted, reviewed and actions tracked to closure.
Obtain copy of last Electrical Hazardous Areas Audit (EEHA) and verify the following:
Has the report been reviewed by the Risk Owner / Control Owner (eg. email, discussion)?
Has an action plan been developed, entered into SAP and actions closed? (Sight evidence of action completion).
Hot Work in areas of Coal Dust Accumulation
• GRM STD Hot Work Standard
• 290.01 GRM SOP Hot Work
• GRM FRM Hot Work Sub Permit
• 280.03 GRM SOP Maintenance of Stockpile Tunnels, Bins, Hoppers and Chutes
Hot work conducted in locations where a potential ignition of coal dust/coal fines is adequately managed ALARA.
Inspect hot-work being undertaken in CPP locations such as tunnels, bins or train load-out and verify the following:
Does job-set-up and housekeeping standards ensure removal of dust build-up to prevent ignition of coal dust?
Is there a hot work permit?
Are the controls identified in the permit in place and effective?
