OSH for a Site Electrician: SEP & Safety

An electrician on a construction site is not the same electrician as in a flat. Here you've got wet ground, temporary rigs, scaffolding, generators, cables thrown into the mud and five other tradesmen who have no idea you're working under the board right now. One mistake with electricity doesn't end in a bruise. It ends in an ambulance, or worse. That's why an electrician's occupational health and safety (OSH) isn't paperwork for the inspector - it's the thing that decides whether you get home in the evening. In this post we'll go through what you need to have sorted: SEP electrical qualifications, measurements, the de-energised working rule and live working. No waffle, tradesman to tradesman. And if you can't be bothered putting documents together from scratch - the BudoReady packages give you ready-made templates you fill in for your own business in half an hour instead of trawling the web.

Key points in brief

• When working on electrical power equipment you must hold valid SEP electrical qualifications - group G1, in the operation (E) and/or supervision (D) variant.
• Without documented as-built measurements (effectiveness of shock protection, insulation resistance) the job formally doesn't exist - the report is proof that you did it right.
• There's one rule: you work de-energised. Live working (PPN) is the exception, which requires a written order and an IBWR.
• Dielectric PPE - gloves, insulated tools, footwear - is not a gadget, it's a condition of survival. And it has to be in working order, not "from last year".
• The most common mistake is improvisation and a lack of reports. The National Labour Inspectorate (PIP) inspector doesn't ask "did you do it", only "show me the paper". The PIP reform from 8 July 2026 tightens this.

SEP qualifications - who, what and for how long

Let's start with the foundation. To legally work on electrical power equipment, installations and networks, you need qualification certificates. Colloquially you call them "SEP qualifications". The basis is the Energy Law act, and the qualification itself you earn by passing an exam before a qualifications board. This isn't a "pass-for-attendance" course - it's an exam you have to pass.

For typical construction work, what interests you is group G1 - electrical power equipment, installations and networks. Within the group there are two types of qualification, and this is where many people get it wrong:

• Operation (E) - this entitles you to direct work: installation, maintenance, repair, servicing, measurements. This is having "hands on the cable".
• Supervision (D) - this entitles you to oversee and direct the work of others, to issue orders. This is what you have when you run a crew or are responsible for the electrical work on a site.

If you're doing the installation work yourself - you must have E. If you direct people who do it, or issue written orders for live working (PPN) - you need D. In practice many experienced electricians hold both. With measurements, be careful: to carry out protective measurements you need operation qualifications in the appropriate scope - the mere fact that you "know your stuff" isn't enough to sign a report.

Validity. Qualification certificates aren't for life - they're issued for a fixed term. Keep an eye on the date on the certificate and renew it in good time, because the exam has to be booked and the board doesn't convene on demand. An expired qualification is as good as not having one at all. On site the main contractor often checks validity when you enter the site - with an expired paper they turn you back at the gate.

Measurements and reports - without paper the job doesn't exist

This is the point where most micro-companies come unstuck. You did the installation properly, it works, the lights are on. But where's the report? Because from the point of view of acceptance, the inspector and any potential claim - if there are no documented as-built measurements, then the job wasn't done properly. Full stop.

The two measurements that come up most often on site:

• Effectiveness of shock protection - you check whether, in the event of a fault, the protective device will trip in time and cut the voltage before someone is electrocuted. This is literally a measurement of whether the installation is safe for people.
• Insulation resistance - you check whether the conductor insulation holds up and there are no leakages. Poor insulation means breakdowns, fires and electric shocks.

You carry out these measurements with a working, calibrated meter, and you record the result in a report. The report isn't a scrap of paper knocked up "on your knee" - it's a document with specific data: what you measured, with what instrument, what the result was, who carried it out (with their qualification number), the date. This paper is your shield. If something happens six months later, the report shows that on the day of acceptance the installation was in working order and measured. Without it, all the liability falls on you with no evidence for your defence.

Practical tip: don't put reports off "until later". Once the work is finished, before you leave the site, you have the full set. The main contractor and the client will demand them for acceptance anyway, and hunting them down after the fact always ends with driving back to the site a second time.

The de-energised working rule - by default, always without power

The sacred rule of electrical work is: you work de-energised. That is, before you touch the installation, you switch off, secure against accidental switching back on, verify the absence of voltage and - where required - earth and short-circuit. Only then do you get to work.

This isn't overkill or "blowing on cold". Most serious electrical accidents come from someone "being sure" it was switched off. Or a mate thought you'd switched it off, and you thought he had. That's why the procedure is rigid:

1. Switch off the voltage on the entire circuit you're working on.
2. Secure against re-energisation - a padlock on the disconnector, a sign "Do not switch on - people working".
3. Verify the absence of voltage with a suitable, working tester - directly at the workplace.
4. Where needed, earth and short-circuit.
5. Mark out the work zone.

This sequence sounds like bureaucracy until you see what electricity does to a person. Drum it into yourself and your crew as a reflex. Work on electrical power equipment counts as particularly dangerous work, so the basic OSH requirements - including the general rules from the Regulation of the Minister of Labour and Social Policy of 26 September 1997 on general OSH provisions - apply to you here with full severity.

Live working (PPN) - the exception, not the norm

Sometimes you can't switch off. You have to measure a circuit under load, connect into a live network, and switching off would mean cutting power to half the estate. That's when live working comes in. But remember one thing: PPN is the exception, for which you need a paper and a procedure - not something you do "because it's quicker".

What you need for it in practice:

• A written order - live working is carried out on a written order, issued by a person with the appropriate supervision qualifications. This isn't a "go and do it" shouted from the other end of the site.
• An IBWR - a Safe Work Method Statement, which describes step by step how this specific job is to proceed, what hazards occur and how to control them. There's more on how to put one together in the post on the IBWR for electrical work.
• Qualifications and equipment - the work is carried out by a trained person with the appropriate qualifications, the right PPE and tools intended for PPN.
• A back-up person - with PPN, as a rule you don't work alone; there's a second person who reacts if anything goes wrong.

If someone on site tells you "wire it up live, there's no time to switch off", and there's no written order and no IBWR - that's not your timing problem, it's your criminal liability and your health. You have every right to say "no".

Dielectric PPE - your second skin around electricity

Personal protective equipment (PPE) for electrical work isn't a hard hat and a hi-vis vest - it's specific dielectric equipment, that is, equipment that doesn't conduct electricity. Without it, working on installations under the risk of voltage is roulette.

The basic set:

• Electrically insulating gloves - matched to the voltage you're working at, tested and in date. A glove with a hole in it or damp with moisture protects against nothing.
• Insulated tools - screwdrivers, pliers, spanners with insulation designed for electrical work. Not "wrapped in tape".
• Electrically insulating footwear - so the ground, a wet board or scaffolding isn't your path to earth.
• Auxiliary equipment - voltage testers, insulating mats, covers - depending on the job.

The key thing many people forget: dielectric PPE has test and inspection deadlines. Electrically insulating gloves aren't a pair of work mitts you wear until they fall apart. They're to be periodically tested and withdrawn when they lose their properties. Keep them in a case, away from sharp tools, and keep an eye on the dates. Equipment in working order is the difference between "it gave me a jolt and I let go" and a fatal accident.

The most common mistake: improvisation and a lack of reports

After years on sites it's clear that electricians don't come unstuck through a lack of knowledge. They come unstuck through improvisation and a lack of papers. These are the two most dangerous sins in this trade.

Improvisation is: "I'll wire it up for a moment without switching off", "these gloves will last a bit longer", "I'll do the measurement later, it works for now", "a written order? come on, we know each other". Every one of those sentences ends badly one day. Not because you're careless - because you do it hundreds of times and the statistics eventually catch up.

A lack of reports is the flip side of the same coin. The job may be done perfectly, but when an inspection or a claim comes, what counts is what you've got on paper. Without measurement reports, without valid qualifications to hand, without an IBWR for PPN - you're standing there empty-handed. And from 8 July 2026 the PIP reform comes in, which tightens inspections and the way the inspectorate operates. That's a bad time to have a drawer full of chaos instead of a complete set of documents.

The simplest defence: have a standard. The same procedures, the same report templates, the same checklist before every job. If you have a fixed template, you don't improvise - you just run down the list.

What documentation goes with an electrician's qualifications

SEP qualifications are the tip. Underneath there's a whole set of documents that someone on site will ask you for anyway - the main contractor, the client or the inspector. It's worth having it sorted in advance, rather than putting it together in a panic on site:

• Copies of valid qualification certificates (E and/or D) for you and your workers.
• As-built measurement reports - effectiveness of shock protection, insulation resistance.
• IBWRs for particularly dangerous work, including PPN and work on electrical power equipment.
• Written orders where you carry out live working.
• Workstation OSH instructions - so everyone knows how to do their job safely. How to prepare these is covered in a separate post on workstation OSH instructions.
• A record of PPE inspections and dielectric equipment.
• OSH training cards and an occupational risk assessment (ORZ) for the electrician's post.

It looks like a mountain of paper, but in practice it's a repeatable set. Once put together properly, it serves you on every site - you just swap the site details and dates.

Put the documentation together once, have peace of mind on every site

If you run a micro electrical company and don't want to spend your evenings cobbling together IBWRs and reports from random files off the internet - that's what BudoReady is for. These are ready-made OSH documentation packages for construction companies with PKD 43, in Polish and Ukrainian versions, to fill in for your own business.

For an electrician the most sensible choice is the FULL package at 749 zł - 45 files, including 6 types of IBWR (so you've got method statements for particularly dangerous work, including electrical, ready to adapt), documents in a Ukrainian version for UA crews, plus a separate set for developers. If less is enough to start with, there's STANDARD at 449 zł (27 files) with a full set of workstation instructions and risk assessments. The promotion runs until 7 July 2026 - that is, just before the PIP reform comes in.
