Transport Canada’s Standard TP14850, “Small Containers for Transport of Dangerous Goods, Classes 3, 4, 5, 6.1, 8, and 9”

Transport Canada is well into the process of producing the 3rd Edition of TP14850. The current 2nd Edition (2010) has been in effect since it replaced the CGSB 43.150-97 standard in 2014. Changes to TP14850 are required to reflect current harmonization with the UN Recommendations, changes in the TDG regulations, improvements to ensure the integrity of standardized packaging, addition/clarification of Part 14 special cases, and simplify use of the standard.

Comments are welcomed until May 31, 2017.

An initial draft update was prepared for discussion in January 2016 and a committee of 30-40 stakeholders has been reviewing, discussing and proposing modifications between the initial draft and the May 2017 draft version of the 3rd Edition (by way of disclosure, the author of this Blog is one of the stakeholder representatives). The May 2017 draft follows these reviews and feedback from an initial 2016 public consultation.

Manufacturer’s Periodic Re-Test Obligation

A new requirement (Clause 7.1.7) requires the registered manufacturer to periodically, at least every 5 years, repeat performance tests on a representative sample. Typically, registration certificates are issued for 5 year periods.

One thing to note is that although TP14850 as currently written/proposed does not define “manufacturer” with respect to obligations under the standard, the application form for registration clarifies, in section 4 and Appendix C, that “…the manufacturer is considered to be the person or corporate entity applying for the Certificate of Registration, even if they do not actually manufacture the containers.

Currently registered manufacturers would have a 2-year transition period from the adoption of the 3rd Edition to comply with the periodic re-test requirement.

Organisation of Packing Instructions

As well as additions/deletions/modifications of packing instructions (PI) to include new or changed UN numbers, Appendix A has been simplified to make it easier for users to find information. Outer (Combination packaging) and single packaging limits, currently in Part B, Table A of Appendix A, will be incorporated into each PI. Also, the Substance Specific Provisions (SSP-currently in a separate Part C of Appendix A) will be listed at the end of each PI.

This follows the convention in both the UN Recommendations and IMDG Code publications.

Although Transport Canada does not currently include PI references in Schedule I, the SSP are listed in order of UN number (or the first UN number in a series when more than one UN number uses the same SSP) at the end of each PI.

Conditional Extension of Life for Plastic Containers

Current standards limit the period that a standardized plastic drum or jerrican can be used for DG, even if it has never been used, to 60 months post-manufacture. Clause 12.2(c) is proposed to be modified by special case (Clause 14.4) that would allow conditional use of fleets of drums or jerricans by a single operator up to 120 months post-manufacture- i.e. an extension from 5 years to 10 years.

The fleet operator would have to be registered with Transport Canada under a requirement in the new Clause 10.12.

Additional Additions – Clarification

The Part 1 proposed modifications include ambulatory references to certain standards (e.g. CSA standards), and additional definitions. Part 5 changes terminology from “markings” to “marks”, adds a requirement to identify salvage containers; Part 6 adds construction requirements for boxes made of metals other than steel or aluminum; new Clause 12.6 adds a reference to TDGR Part 11 regarding containers for marine transport; Clause 13.4 clarifies that salvage container absorbent must only be sufficient to eliminate free liquid present when the container is being closed; Part 14 re-defines special cases regarding waste, and adds Clause 14.3 regarding Mobile Process Units used under the Explosives Act/Regulations.

Next Steps

The committee will review a “final” draft following this consultation. Transport Canada then expects to do the final edit and publication of the 3rd Edition in Q4/2017 or Q1/2018.

Existing Manufacturer registrations issued under the current 2nd Edition would continue to be valid to their current expiry date, unless otherwise revoked.

Those interested can request a copy of the May 2017 draft, and/or submit comments by May 31 at:
