ISO 45001:2018 for trades
ISO 45001 for trades: certificate for your business
General contractors, building owners and purchasing departments want to know how a subcontractor manages safety on site. ISO 45001 answers that question with a certificate they can verify. With Zertify you answer 34 questions online, without an on-site audit.
01: Demand
Why do clients and tenders ask for ISO 45001 in the trades?
A subcontractor's people work on someone else's site, in someone else's building, often next to other trades. If one of them is injured, the client feels it too: work stops, an investigation starts, the schedule slips. That is why supplier questionnaires from larger customers now contain a section on occupational health and safety.
A certificate against ISO 45001 replaces a page of self-description with a document. Some tenders ask for proof of an OH&S management system, and customer audits go faster when the answer is already on file. Your own staff benefit too: a foreman who knows the hazards of the next job plans it differently.
Every Zertify certificate carries a number and a QR code. The purchasing department scans the code on the PDF and lands on a public verification page. Nobody has to phone you to confirm it.
02: Hazards
Which hazards in the trades does ISO 45001 address?
The standard does not hand you a fixed list of hazards. It requires you to identify the hazards of your own work and to decide what to do about them. In a trades business they usually look like this.
- Work at height
- Ladders, scaffolds, roofs and lifting platforms. The hazard is assessed per job, and the control is chosen before the first person climbs.
- Power tools and machinery
- Saws, grinders, drills and compressors. Guards, training, inspection of cables and blades, and a clear rule on who may use what.
- Dust, noise and vibration
- Cutting, chiselling and sanding expose workers over months and years. The harm is slow, so it needs a plan rather than a reaction.
- Hazardous substances
- Solvents, adhesives, paints and cement. Safety data sheets at hand, labelled storage and a check whether a less harmful product does the same job.
- Manual handling
- Plasterboard, pipes, bags and tiles. Lifting aids, team lifts and delivery to the point of use instead of the ground floor.
- Several trades on one site
- Someone works above you, someone else leaves cables across the corridor. Coordination between companies is part of your own risk assessment.
03: Requirements
How does a trades business meet the key requirements?
Most of what ISO 45001 asks for already happens in a well-run workshop. The standard asks you to make it deliberate and to keep a record.
| Requirement | Clause | Example in a trades business |
|---|---|---|
| Identify and assess hazards | 6 Planning | Before each larger job the foreman lists the hazards on a one-page checklist: height, electricity, dust, other trades. |
| OH&S policy with a commitment to prevention | 5 Leadership | The owner signs a short policy and pins it in the workshop and the site van. |
| Consult and involve workers | 5 Leadership | A ten-minute safety talk each week, and apprentices are asked what felt unsafe. |
| Apply the hierarchy of controls | 8 Operation | Wet cutting or extraction instead of dust masks alone. Protective equipment is the last step, not the first. |
| Plan emergency preparedness | 8 Operation | Named first aiders per crew, a stocked first-aid kit in every vehicle, the site address noted before work starts. |
| Investigate incidents and derive actions | 10 Improvement | A near miss with a falling tool is written down, discussed, and the tool lanyards are bought. |
The hierarchy of controls is the idea that changes most habits. Eliminate the hazard first, then substitute it, then protect people with technical measures, then with rules and training, and only then with personal protective equipment.
04: Preparation
What does a small trades business need to have in place?
A team of five does not need a safety department. It needs a few documents that are true and a routine that people follow.
List the hazards by trade
Walk through your typical jobs, from a bathroom renovation to a roof repair, and write down what can hurt someone.
Write a short OH&S policy
One page, signed by the owner, with a commitment to prevent injury and ill health.
Ask your workers
Collect their view on hazards and on what already works. Note who was asked and when.
Fix controls and emergency steps
Decide who is responsible for scaffolding checks, substance storage and first aid.
Record incidents and near misses
A simple log is enough, as long as every entry leads to a decision.
05: Zertify
How do you get ISO 45001 for a trades business with Zertify?
You complete an online self-assessment with 34 yes/no questions. 14 of them are mandatory requirements of the standard and must all be answered yes. Of the other 20, at least 14 need a yes. Once you have passed and paid, the certificate arrives within 4 hours. You need no account to buy.
The certificate is issued by G6 Agency AG under licence from SICE, the Swiss Institute of Certification and Education. SICE reviews every assessment before the certificate is issued. There is no on-site audit. Each year a short online re-audit confirms the certificate, and it is valid for 3 years.
The price is CHF 699 (€699) in the first year, then CHF 469 (€469) per year including the online re-audit. It runs as an automatic yearly subscription. You can cancel it at any time in your customer account, effective at the end of the current year, and the certificate then ends with the paid year. Companies that certify against two standards get 20% off, three or more get 30%, also on the yearly fee. Customers in Switzerland and Liechtenstein pay prices including 8.1% VAT.
06: Routes
Online self-assessment or the classic audit route?
The classic route means an on-site audit by a certification body. It suits companies whose customer or tender explicitly demands one. It also takes more time to arrange, because auditor, site visit and your own working days have to fit together.
If your customers mainly ask for a valid, verifiable certificate, the online route covers that. Read the tender or the supplier questionnaire first and see what exactly it asks for. The guide on the routes compares both.
