An installation, maintenance, fire safety or service engineer has no workplace. He has a route. Monday a boiler room in a hospital, Tuesday a distribution centre with forklifts moving behind him, Wednesday a school during term time, Thursday a plant where a permit desk decides whether he gets past the turnstile. Every other frontline role is trained against a place that stays the same. This one is not.
Same job description, different hazard sheet every morning
The work in the van is stable. The conditions around it are not. Yesterday's job had a lift and a clean floor; today's has a ladder, live process equipment two metres away, and a client who wants the line back by three. The competence is identical, the risk is not, and the risk is what instruction must cover.
Codex art. I.2-21 asks for training aimed at the worker's workpost or function, repeated and adapted as risks evolve. Arbowet art. 8 lid 2 asks for instruction adapted to distinct tasks. Against a job list of four addresses a week, both are asking for something that keeps arriving.
No colleague standing next to him when it goes wrong
Most safety systems quietly assume someone more experienced is within earshot. A technician working alone or in a pair has nobody to ask, and the colleague he could call is driving to his own next job. Whatever he did not understand before leaving the depot, he resolves on the spot with a customer watching. That raises the bar on what lands before departure: fewer things, understood properly, and available again on the phone at the moment he needs them.
Two rulebooks apply at once, and the second one governs the floor
He carries his employer's procedures. The building has its own: access, permits, hot work, evacuation routes, which door is not an exit. Where they differ, the client's rules govern that floor.
The Belgian Welzijnswet of 4 August 1996, art. 9 says so from the other side. A client in whose establishment external contractors work must inform them before work begins about the risks, prevention measures, emergency procedures, first aid, fire fighting and evacuation, and must verify that the contractor's workers received the appropriate training and onthaal (structured reception and induction). Your client is legally obliged to check you. The polite version of that check is a question from procurement; the impolite version is a technician sent back to the gate.
The card in his wallet does not answer the site question
VCA is not law. The law is the Arbowet in the Netherlands and the Welzijnswet plus the Codex in Belgium; VCA is how clients verify you follow them.
A B-VCA (Basisveiligheid VCA) shows he passed a general safety exam. It runs ten years, then a full re-examination rather than a refresher, and it says nothing about the address he enters this morning. The checklist keeps the two apart on purpose: question 3.6 is a separate must question requiring instruction on the internal rules and procedures at clients' sites, including for temporary workers and subcontractors, before work begins at that location, demonstrably, with attendance lists. A folder of diplomas answers 3.2 and leaves 3.6 wide open.
The sixty seconds that belong to whoever is holding the tool
Question 2.3 requires a Last Minute Risk Analysis before work starts, separate from the task risk analysis under 2.2 that someone wrote in advance. For a lone technician this is the only control that exists when reality differs from the work order, so it has to be short enough to do standing at the door and specific enough to be worth doing.
From a client rulebook to ten minutes before the door
You already hold the material: work instructions, the site rules a client sent through, the findings from the last incident investigation. Aristotl turns those into modules of three to five minutes a technician finishes on his own phone before the first job, with no laptop and no app to install. Courses are assigned per client site, so the man going to that plant gets that plant's rules, translated per worker, with completion recorded per person, per site and per version.
Bring one client's site rules and next week's job list to a demo, and we will show you what your technicians receive on Monday morning.
