If your safety procedures and training are delivered in English and your workforce speaks five other languages, you may already be carrying a risk you can't see.
A safety procedure is only effective when every person on site can understand and act on it with confidence. Yet on a multilingual site, workers and contractors may be expected to rely on instructions written or delivered in a language they do not fully understand. This creates a hidden gap between having the right procedures in place and knowing they will be followed correctly.
In this article, we explore why you should localise safety procedures and training before an incident forces your hand. If you manage a multilingual site with rotating contractors, English-only SOPs, inductions and training can leave critical instructions open to misunderstanding. By acting now, you can reduce risk, strengthen compliance and give every worker the information they need in a language they fully understand.
When an industrial accident happens on your site, one of the first questions investigators ask is whether your workers understood the procedures and training they were given.
The pattern is often the same: an investigation begins, operations are disrupted or the site is closed, and you are told to translate procedures and retrain workers under intense regulatory scrutiny. At that point, localisation becomes a crisis response, more expensive, more rushed and more vulnerable to errors than a planned programme completed before anything goes wrong.
In November 2023, an agency worker at Flowchem UK’s Nottingham manufacturing site suffered chemical burns after opening the wrong valve on a 1,000-litre container of corrosive drain cleaner. The Health and Safety Executive found that the company’s training arrangements did not provide adequate information for workers with limited English; in February 2026, Flowchem UK was fined £50,000 and ordered to pay £7,247.40 in costs.
Drawing on experience supporting industrial operations across Asia, Paul Evans, Founder & Director of MEP Advisory Services Limited, states:
"After a serious safety incident occurs on site, one of the typical actions is to look at enhancing existing site procedures or introducing new procedures. However, in my experience, this often does not address the root cause. If the original procedure(s) had been properly communicated and applied, the incident might have been avoided.”
Why language sits behind so many safety failures
Your workers can only follow a procedure they fully understand, and on many industrial sites, a large share of the workforce is working in a second or third language. In England and Wales, 5.1 million people speak a main language other than English, and around 880,000 of them could not speak English well; while 161,000 could not speak it at all.
The research links language directly to harm. A 2024 review in The Lancet Public Health found migrant workers had a 71% higher risk of fatal injury at work, and across the five studies examining language, those with lower proficiency in the local language consistently had higher fatality rates.
The HSE is clear on what employers must communicate: work instructions, risks, precautions and emergency procedures, in a way every worker can understand. In practice, that means onboarding, permit to work, lockout and isolation, emergency response and incident reporting documents.
Your procedures are only as good as the training behind them
Your workers rarely learn a safety procedure by reading the SOP itself; they learn it through an induction video, an eLearning module or a toolbox talk, and if those are in the wrong language, the procedure never end up being understood.
Secondly, the format of training can be as important as the language itself. With years of experience supporting multilingual industrial workforces, Paul Evans explains:
"Using media to show real-life examples of what can go wrong if procedures are not followed has a much higher learning value than just setting out the 'rules' to be followed in a written document.”
Video helps where literacy varies, though the format alone is not enough. A 2021 study found workers with no English learned more from a wordless animated safety training than from an English version, while workers who spoke English did better with the English version, so the right format depended on the workers' language.
Records matter as well, OSHA (Occupational Safety and Health Administration in the US) directs its inspectors to check and verify that training was provided in a format workers could understand, so a record of who completed which module in which language answers the question an inspector will ask.
Finally, the terminology in the video, the module and the written SOP should match, so workers hear the same instruction everywhere.
Why wait for an incident?
Every day, your site stays closed after an incident costs you far more than localising your procedures and training would have done in the first place. The bill for an incident arrives from several directions at once: fines, legal costs, lost production and the time of the regulator's inspectors, which in Britain the HSE charges back to the business by the hour.
Localising before an incident is now far more achievable, as AI has made translation quicker and more cost effective. Safety procedures still need human judgement, so AI brings the speed while qualified linguists verify every instruction and answer for it before it reaches your workers.
Choose your options wisely
You could run your SOPs and training scripts through a free AI tool, but if a regulator later finds a gap, your organisation carries the consequence.
Accuracy also varies sharply by language. A study of Google Translate for emergency department discharge instructions found accuracy of 94% for Spanish but just 55% for Armenian, this means a single mistranslated verb can reverse an instruction.
Guildhawk’s end to end training localisation service closes that gap. Our qualified linguists check every instruction against approved terminology, and each review is recorded, giving you an audit trail that shows what was translated, who verified it and when. We make a localised procedure defensible.
Three steps to protect your sites
1. Localise your SOPs and the training that delivers them, before an incident. Cover written procedures, eLearning modules and induction videos together, so every format tells workers the same thing in the same terms. A procedure translated on paper but left in English on screen still leaves a gap.
2. Use safe, secure technology. Your SOPs describe how your sites run, which makes them sensitive operational data. Sovereign AI with ISO 27001 controls speeds up translation, subtitling and module localisation while keeping that information inside a governed environment.
3. Keep an expert human in the loop. A qualified linguist verifies every high-risk procedure and script, and each review is recorded. So, when a regulator, an auditor or a court asks whether your workers understood their training, you have the evidence to answer.
Why choose Guildhawk
Your procedures protect your people only if everyone on site can understand them, and in scientific, digestible formats.
Just as Paul Evans states, “Regulators will pay particular attention to what training has been given and what pre-work safety briefings have been conducted”.
Guildhawk brings document translation, eLearning localisation and video production together under one governed process, so your SOPs, modules and induction videos use the same verified terminology in every language. We are built for sovereign deployment under ISO 27001 and ISO 9001 controls, keeping your operational data secure, and high-risk content escalates automatically to our network of more than 3,000 certified linguists, working across over 200 languages.
