Safety instruction for staff who work on client sites

An installation, maintenance or service engineer has no workplace. They have a route. Monday a boiler room in a hospital, Tuesday a distribution centre with forklifts moving behind them, Wednesday a school during term time, Thursday a plant where a permit desk decides whether they get past the turnstile. Every other frontline role is trained against a place that stays the same. This one is not, and neither is the cleaning crew that arrives at 05:40 after everyone else has gone.

Same job, a 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.

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 asks for instruction adapted to each worker's tasks. Against a job list of four addresses a week, both are asking for something that keeps arriving.

Two rulebooks apply at once

The technician carries the 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.

Belgian law says so from the other side. Art. 9 of the Welfare Act of 4 August 1996 requires a client in whose establishment external contractors work to inform them before work begins about the risks, prevention measures, emergency procedures, first aid, fire fighting and evacuation, and to verify that the contractor's workers received appropriate training and onthaal. 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.

Electrical work adds a layer in Belgium: the employer designates workers as BA4 (instructed) or BA5 (skilled) persons before they work on or near electrical installations.

The card in the wallet does not answer the site question

VCA is not law. It is how clients check that you follow the law, and in practice it decides site access and tender lists. In Belgium the scheme is run by BeSaCC-VCA, in the Netherlands by the SSVV.

A B-VCA certificate shows a person passed a general safety exam, and it runs ten years before a full re-examination. It says nothing about the address they enter this morning, which is why the checklist asks separately for instruction on each client's internal rules before work starts there, with attendance lists. How the diploma and instruction questions split is set out in VCA training across multiple sites.

The sixty seconds at the door

VCA asks for a last minute risk analysis before work starts, separate from the task risk analysis someone wrote in advance. For a technician working alone, the LMRA 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.

A technician working alone or in a pair has nobody to ask, and the colleague they could call is driving to their own next job. Whatever they did not understand before leaving the depot, they resolve 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 they are needed.

Cleaning crews: 05:40, and the building is empty

Offices are cleaned before people arrive, shops after closing, production areas in the changeover window. The two mechanisms most companies rely on to make instruction stick, a supervisor who sees the work and a colleague who can be asked, are both absent. What the cleaner does not know at 05:40 gets improvised, and the improvisation becomes the method.

A cleaner on three sites in one week works under three sets of rules: where the waste goes, which areas are restricted, the alarm procedure, which floor cannot take water. Products are the part with a hard instruction duty attached. Dosing, dilution, which product never meets which other, gloves and eye protection, and what to do about the unlabelled container in the cupboard. A new product is exactly the kind of change Codex art. I.2-21 names as a trigger, and art. I.2-20 adds that only workers who received appropriate instructions may enter zones with serious and specific hazards.

Teams turn over fast and many arrive through agencies. One correction worth making: the werkpostfiche for agency workers is required only for workposts under mandatory health surveillance (Codex Book X, Title 2). Where it applies, the worker may not start on that post without it. Where it does not, the instruction duty still does.

How Aristotl handles it

Aristotl turns the material you already hold, work instructions, the site rules a client sent, product sheets and the findings from the last incident, into courses of 3-5 minutes a technician or cleaner finishes on their own phone before the first job, with no laptop and no app to install. Your team reviews each course and nothing goes live until you publish. Each person reads it in their own language.

Set up each client as a site or team, so the person going to that plant gets that plant's rules instead of a generic module. Subcontractors and agency staff join with a link or QR code, without a company email. Installation and inspection steps run as checklists with a photo, signature or reading per step; a toolbox meeting can run as a checklist with a signature step, and the day log exports as CSV or PDF when a client asks for attendance. Toolbox topics and incident lessons go out as must-acknowledge updates with named receipts.

What it does not replace: the task risk analysis, a practical competence assessment, supervision on site and any legally required certification.

Take the site rules of one client and next week's job list, and check whether everyone on that list could tell you the emergency procedure at that address before they arrive.
