What is going on

A road tanker carrying 20 tonnes of 32 percent hydrochloric acid arrives at loading bay 1 at 8:30 am for tank T-105. The last receipt into T-105 reached 92 percent and activated the high level alarm, and the investigation is open, so receipts are restricted to supervised transfers with a manual dip before and after and a second person checking the ullage calculation. The tank data sheet gives the tank capacity, the safe fill level and the receipt margin. The automatic gauge reads 39 percent, but the weekly manual verification is two days overdue. The driver is new to the site. Aisha Rahman wants the whole receipt recorded in the transfer register with the reconciliation.

Aisha Rahman, Terminal Manager
Subject: Hydrochloric acid receipt to T-105 on Tuesday

A road tanker of 32 percent hydrochloric acid arrives on Tuesday morning for T-105. The last receipt tripped the high level alarm at 92 percent and the investigation is still open, so receipts to that tank are only allowed under a supervised transfer with a manual dip before and after. I want you to run the receipt from start to finish under the bulk transfer procedure: ullage calculation, overfill protection check, line-up, driver briefing, the transfer itself, drain-back, gauging and reconciliation. Enter it all in the transfer register.

Your brief

Receive the tanker safely under the bulk fluid transfer procedure and the current restriction: verify the delivery, calculate and check the ullage with a manual dip, confirm overfill protection, complete the line-up and driver briefing, run the transfer while monitoring, drain back, disconnect, gauge and reconcile, and record the receipt.

Work through it

You do not need to do it all. Doing a few of these will show you what the work is like. Your ticks and notes stay on this device.

Read the bulk fluid transfer and tank gauging procedure and the dangerous goods storage and handling policy, and note the current restriction on T-105 receipts from the notice board.
Check the delivery documents against the order and the tank service for T-105, and confirm the driver's dangerous goods licence and site induction.
Take a manual dip of T-105, compare it with the automatic gauge, calculate the available ullage against the safe fill level and the receipt margin and have Sam Whitford check the calculation.
Confirm the high level alarm and high high trip status on the safety critical equipment register and report to the shift supervisor before starting.
Walk the line-up using the transfer checklist, inspect the hose and couplings, check the spill kit and emergency shower and brief the driver on the emergency stop and the protective equipment.
Run the transfer while remaining at the transfer point, monitoring level and pressure, and stop the transfer at the planned quantity or on any abnormal indication.
Drain back the line, disconnect and cap the coupling, take the post-receipt manual dip, reconcile the quantity received against the delivery document and record the receipt in the transfer register with any variance.
