No. | Step | Potential Hazard | Required control |
1 | Examine and wear personal protective equipment | Utilisation of Inappropriate PPE | Wear the prescribed PPE. |
2 | Ensure that the Long handle Scoop or scraper is in good condition | poor clearing of solid from filter cloth | If the scoop is damaged, report and request a new scoop. |
3 | Ensure the filtration slurry density is not more than 40% and pressure gauge is on the 0.8 kPa | Poor separation of slurry components | Ensure the slurry Pumps are effective |
4 | Regulate filtration batch between 12 to 14 minute | Poor cake (solid) formation | Report malfunctioning of Filter Press sections |
5 | Ensure the readiness of partner operator | Personal injury | Verify the position of partner |
6 | Position the filter plate at clearance mode | Poor solid clearance | Ensure elimination of friction on the moving parts |
7 | Ensure that clean filtrate flow through the discharge launder leading to the settling pond | Poor solid cake formation | Make sure worn-out filter cloths are changed before filtration start |
8 | Submerge the flat part of the scraper into the solid on the filter cloth | Damage of filter cloth | Clean scraper after every batch |
9 | Sample the solid and the filtrate for Internal laboratory test | Environmental hazard | Ensure clean sampling bags and bottles are available |
10 | Clear off all solid on the surface of the filter cloth unto the concrete floor for offloading to Pit | Poor filtration during subsequent batch | It is good practice to clean all needed equipments for effective operation |
11 | Ensure the good operation condition of standby tailing press and ancillaries are met and ready to run when needed | Stoppage of plant and lost production Environmental hazard | Test start all standby equipments that relate to the operation of standby tailing Filter press |
12 | Solution (Filtrate) and solid (cake) Sample submission to external laboratory for testing | Violation of regulatory agencies’ policies | Ensure well labelled samples are available for submission |
