Lithium Battery Parcels in a 24-Hour E-commerce Fulfilment Centre

What is clear. Undeclared lithium batteries in a general storage building, no dangerous goods licence, an unreported fire-related incident, and waste containing damaged cells placed in a general bin. Each of these is a problem independent of the others, and together they describe a system with no control at the receiving door.

First 72 hours. Quarantine the sorter bay and any residue; preserve the parcel, the CCTV and the sorter logs; stop dispatch of the affected seller's SKUs pending verification. Suspend the free-text declaration immediately and replace it with a mandatory structured field plus a hold rule - a route change, not a policy document. Segregate any batteries found on site into a fire-rated cabinet away from the main storage and outside the general waste stream. Brief the shift on what to do next time: isolate, evacuate, call, do not use a hose reel on a cell fire as a first action.

Regulatory position, subject to confirmation with the Fire Services Department. Storage and conveyance of Class 9 lithium batteries fall under the Dangerous Goods Ordinance (Cap. 295) and its subsidiary regulations, with licensing and quantity thresholds set by the Fire Services Department; a general storage licence does not authorise dangerous goods above the applicable exempt quantity. I would not assert a specific threshold in a letter - I would obtain the applicable quantity limits and licence conditions in writing, and check the position on damaged or waste cells under the waste disposal and fire safety regimes. The incident should be disclosed to the Fire Services Department and the insurer now, not reconstructed later.

What I would not do. Sign a compliance assurance before the controls exist. That is the highest-risk action available in this scenario.

Onboarding (upstream). Every seller declares battery content at listing level, with documentary evidence: UN 38.3 test summary, safety data sheet, and the correct UN number and packing instruction for the mode of carriage. No evidence, no listing. The declaration becomes a mandatory structured field in the WMS that blocks despatch if incomplete - the current free-text field is the root cause of 15.5% undeclared shipments.

Receiving and screening. Weight-and-dimension plausibility checks against declared SKUs, targeted X-ray or explosive-detection screening for high-risk categories (power banks, e-bike packs, replacement laptop batteries), and a rule that any parcel over a defined battery energy threshold is routed to a manual dangerous goods bay. Audit a statistically meaningful sample weekly and publish the undeclared rate by seller.

Storage and handling. A dedicated dangerous goods store with fire-resisting construction, appropriate suppression and early detection (aspirating smoke detection or thermal imaging), segregation from flammables and from general stock, a maximum aggregate quantity per bay, and a physical barrier from the sorter. Battery parcels should not pass through an unattended 24-hour sorter without detection coverage and a shutdown interlock.

Emergency preparedness. A lithium battery response kit (appropriate extinguishing media for the cell chemistry, thermal gloves, tongs, a containment vessel), a documented emergency plan agreed with the Fire Services Department, at least two trained responders per shift, quarterly drills, and a notification flowchart that names who calls whom and within what time.

Returns and damaged cells. Never re-enter the general inbound flow. A separate returns quarantine with external access, a damaged-battery log, an approved downstream recycler with a waste flow record, and no damaged cell placed in a general waste bin under any circumstances.

What I write. A factual statement of current status and a dated remediation plan, not an unqualified assurance. Concretely: the categories and quantities handled, the controls now in place (mandatory declaration, screening, segregated store, detection, training, emergency plan), the controls not yet in place and their completion dates, the incident disclosure with its investigation reference, and a named accountable person. For carriers, a statement of what is tendered for carriage and under which packing instruction, with the residual risk that undeclared seller content is being driven down and measured - carriers can work with a measured rate; they cannot work with a false zero.

What governs it. The professional duty is to public safety first, then honesty to employer, client and third parties, and competence within the limits of one's own knowledge. That produces three specific behaviours. First, do not certify dangerous goods classification or packing instructions unless qualified - engage a competent dangerous goods safety adviser and say so. Second, do not let a commercial deadline convert an uncertainty into an assurance; an inaccurate statement to a carrier or an insurer is misrepresentation, and it will be the document that is produced after the next incident. Third, disclose the earlier non-notification rather than leave it to be discovered.

How to handle the director. Reframe the deadline. The letter can be signed this week - as an interim, qualified disclosure with a remediation schedule. What cannot be signed is a compliance statement that is not true. Offer the alternative and put the advice in writing, copied to the quality and insurance functions, so the decision to proceed is an informed one at the right level. If pressed to sign an untrue statement, escalate and decline; that is the point at which the duty to the public and to the profession overrides the instruction.
