CFP ADR Esplosivi common mistakes
CFP ADR Esplosivi · Understand the traps and how to avoid them.
Classifying a substance by its commercial or trade name (e.g. "gelignite", "emulsion explosive", "firework battery") instead of assigning it to UN 0331/0332/0241 or the correct 1.1D–1.6N entry based on the test data in the classification procedure.
Candidates memorise a few famous UN numbers and then pattern-match on the product name; explosives are the one class where the proper shipping name is driven by the manufacturer's classification and the competent authority's approval, not by what the substance is called on the market.
What to do instead
Always start from the classification hierarchy in ADR 2.2.1: is it an explosive by the 2.2.1.1 criteria, which division (1.1–1.6) by the hazard characteristics, and which compatibility group (A–S, N excluded from 1.6)? Then read the name off the Dangerous Goods List for that UN number. Practise with the generic entries (UN 0475, UN 0476, UN 0482, UN 0491) and the article entries (UN 0431, UN 0432, UN 0508) until you can explain why a 1.4S article is not a 1.4D article.
Treating the compatibility group letter as interchangeable with the division number - for example assuming that anything in 1.4 is automatically group S, or that group D always means 1.1.
The division describes the hazard (mass explosion, projection, fire, negligible hazard) while the compatibility group describes what may be carried with what. Candidates conflate the two because both appear in the same four-character code (e.g. 1.1D).
What to do instead
Learn the two axes separately and test yourself with mixed codes: 1.1D, 1.2D, 1.3G, 1.4G, 1.4S, 1.5D, 1.6N. Then apply the mixed-loading table in ADR 7.5.2.2 to confirm you know why 1.4S can generally be carried with other goods while 1.1D cannot be carried with 1.3G without segregation.
Completing the transport document from the consignor's commercial invoice and omitting the elements ADR 5.4.1 requires for Class 1: the total quantity of explosive substance in kg, the net mass of explosive content, and the additional information required for 1.4S or for articles.
Candidates copy the general 5.4.1 checklist and forget that Class 1 has extra mandatory fields, and they confuse gross mass of the package with net explosive content.
What to do instead
Build a fixed Class 1 transport-document template and rehearse it: UN number, proper shipping name, class 1, compatibility group, division, number and description of packages, total quantity (net mass of explosive content in kg, or gross mass for articles), consignor and consignee, plus the tunnel restriction code and any special provision text. Check the document against the consignment line by line before signing.
Choosing packaging by what is physically strong enough rather than by the packing instruction and the RID/ADR packing group/division combination, and reusing a package that previously held a different explosive without confirming it is permitted.
Explosives packaging is prescribed by P instructions tied to the UN number, with specific requirements for inner packagings, cushioning, and closure; candidates reason from general packaging-group logic (which does not apply the same way to Class 1) and from what is available in the warehouse.
What to do instead
For every consignment, look up the UN number in the Dangerous Goods List, read the packing instruction column, and open the P instruction to check the permitted packaging types, the maximum net mass per package, and any special packing provisions (PP). Confirm the packaging bears the UN mark and that its code matches the instruction. Never substitute a package because it "looks equivalent".
Marking and labelling the package with the class 1 label but omitting the compatibility group letter, or placing the letter where it is not visible after the package is closed and stacked.
Candidates treat the label as a generic "explosive" sticker and do not realise the compatibility group letter is a mandatory part of the Class 1 label and must remain legible in normal handling and stowage.
What to do instead
Apply the Class 1 label with the division and compatibility group letter, plus any subsidiary risk labels, on the same surface, and physically inspect a finished package from the outside in its stowed orientation. Include this in the pre-dispatch checklist and in the loading-supervisor briefing.
Loading or unloading an explosive vehicle without the required supervision, without the correct placarding and orange plates, or with the engine running and without the prescribed fire-fighting equipment and wheel chocks in place.
Candidates learn the vehicle equipment list as a memory item but do not connect it to the operational sequence of loading and unloading, and they underestimate how strictly ADR 8.3–8.5 and the Class 1-specific rules apply to every stop.
What to do instead
Rehearse the full stop sequence: park on firm ground, apply parking brake and chocks, switch off engine, no smoking or naked flame, correct placards and orange plates fitted, fire extinguishers accessible, supervision maintained, and only authorised persons present. Use a laminated pre-loading and pre-unloading checklist carried in the cab.
Assuming the standard ADR vocational training certificate (driver CPC-type ADR card) is sufficient for Class 1, and not checking whether the driver holds the Class 1 extension and whether the certificate is valid for the specific division being carried.
The ADR driver training framework treats Class 1 as requiring additional specialist training beyond the core and tank modules, and candidates often study only the core module syllabus.
What to do instead
Confirm the driver's ADR certificate shows Class 1 in the relevant column and that the special training for Class 1 has been completed and recorded. Verify the expiry date and the categories covered before assigning the driver, and keep a copy in the transport file.
Treating the CFP (certificato di formazione professionale) as a purely administrative document and ignoring the requirement that the person responsible for safety (consulente ADR) must have specific competence for the classes carried, including Class 1.
Candidates conflate the driver's ADR certificate with the consulente ADR's professional qualification and assume one certificate covers everything.
What to do instead
Distinguish clearly: the driver needs the ADR vocational certificate with Class 1; the consulente ADR needs the CFP under the national scheme with the relevant class coverage. Check both documents, their validity, and the scope of classes before the journey, and record the check.
Writing an emergency plan that only says "call the fire brigade" and does not address the specific hazards of the division carried: mass explosion, projection, fire, or the need to evacuate to a defined distance and to account for compatibility-group interactions.
Candidates reuse a generic road-transport emergency card and do not differentiate between a 1.4S load and a 1.1D load, so the response is either over-reacting to a minor incident or dangerously under-reacting to a mass-explosion risk.
What to do instead
Build the plan around the division and compatibility group: for 1.1 and 1.2 assume mass explosion and projection and set evacuation distances accordingly; for 1.3 assume fire and projection; for 1.4 assume minor hazard; for 1.5 assume mass explosion but low sensitivity; for 1.6 assume negligible probability of accidental initiation. Include notification to the authorities, isolation of the area, and the role of the consulente ADR and the consignor.
Treating the D.Lgs. 81/08 obligations and the ADR obligations as two separate worlds - for example completing the ADR transport document but not updating the risk assessment, the DUVRI, or the coordination with other contractors on a site where explosives are loaded or unloaded.
Candidates study the two frameworks in separate modules and do not see that loading and unloading of explosives is a workplace activity governed by the D.Lgs. 81/08 risk assessment, the coordination of interfering activities, and the training of workers, in addition to the transport rules.
What to do instead
For each site where explosives are handled, verify that the risk assessment identifies the explosive hazards, that the DUVRI or coordination plan covers the interface between the site operator and the carrier, that workers have received specific training and information, and that PPE and emergency procedures are consistent with the ADR emergency plan. Cross-check the two documents before the first movement.
