Study Notes
Loading and Offloading the Ferret
-
Inspection is crucial before loading and offloading the Ferret and Road Trucks.
- This step ensures compliance, prevents unexpected breakdowns, and maintains roadworthiness.
- Refer to the checklist: This comprehensive document ensures the Ferret and trucks are in optimal working condition, specifically verifying the functionality of offloading valves and the top hatch.
-
Loading product from hoppers:
- Receiving the certificate of analysis: This document verifies the product's quality and ensures it meets the required specifications.
- Preventing errors in loading: Loading the wrong product can lead to customer complaints, delays, and financial loss. Accurately select the correct hopper to ensure the right product is loaded.
-
Positioning the Ferret/Bulk Truck:
- Positioning under the loading chute: This alignment prevents spillages, ensures safe product transfer, and avoids slippery surfaces on the road.
- Checking for empty Ferret/Bulk Trucks: The presence of any product in the Ferret can result in mixing different products, leading to customer dissatisfaction.
-
Lowering the loading sock:
- Alignment is essential: A misaligned sock can lead to product spillage, creating slippery road surfaces and unsafe conditions.
-
Opening the pneumatic slide valve:
- Securing the flaps: Ensuring the proper positioning of the flaps on hoppers D and E prevents accidental spillage during the loading process.
- Opening the valve: Open the pneumatic slide valve to allow the product to flow into the Ferret/Bulk Truck.
- Monitoring product flow: Continuously observe the flow rate and adjust the slide valve as needed.
- Addressing product clumping: Vibrator activation or using a rubberized hammer on the hoppers helps loosen any clumps obstructing the product flow.
-
Closing the pneumatic air valve:
- Closing the valve is critical: This action stops the product flow into the Ferret/Bulk Truck and prevents overfilling, which can cause spillage and costly cleanup.
-
Weighing the full Ferret:
- Accuracy is vital: Weighing the full Ferret accurately allows for tracking and accounting for the product transported to the Bulk Store.
-
Receiving the weighbridge ticket:
- Traceability and record-keeping: The weighbridge ticket provides detailed information, including the source weight and destination, for efficient traceability and record purposes.
-
Offloading the Ferret:
- Precise positioning: The Ferret needs to be parked directly above the offloading hatch to avoid spillage and related safety risks.
- Verifying system status: Confirm that the conveyor system is operational to ensure the product is transported to the selected bay in the Bulk Store.
- Controlling the offloading valve: Open the valve strategically to offload the product without overflowing the conveyor, which would create slippery floor conditions.
Cleaning Inside Hoppers
-
Prioritizing safety: Wearing the correct PPE and using a functional safety harness is crucial for the safety of the cleaning personnel.
-
Thorough inspection: Inspect the hopper for product remnants, fines, and the availability of space for the ladder.
-
Oxygen level checks: Ensure adequate oxygen levels in the hopper by testing using an oxygen meter. The reading must be at least 18% for safe entry.
-
Securing the conveyor: Use a lockout set to prevent any product flow into the hopper during the cleaning process.
-
Ladder inspection: Inspect the ladder for grip and security before entering the hopper.
-
Cleaning process:
- Supervision: A standby observer must monitor the cleaning process from the entrance chute/manhole.
- Careful cleaning: Use a rubber hammer to clean the hopper, taking care to avoid dislodging clumps of material.
- Monitoring fines flow: Constantly check the flow of fines during the cleaning process to ensure that the outlet loading pipe is not blocked.
Reclaiming Fines from Bay 11
- Safe and accessible work environment: Inspect the bay for accessibility, ensuring clear space for movement and no obstructions from moving equipment like the arm scraper.
- Space assessment: Verify adequate space for the scooper before proceeding.
- Scooper inspection: Inspect the scooper for safe operation and ensure it is in good working condition before entering the Bulk Store.
- Supervision: A standby person should provide directions to the scooper driver, especially when navigating near the edge of the bay.
- Risk assessment: If insufficient space is available, conduct a risk assessment before proceeding to avoid potential accidents.
