Translating Health and Safety Training for Foreign Workforces

When a company employs foreign workers in roles that involve physical, chemical, or mechanical hazards, health and safety training must reach every employee in a language they understand. This is not a matter of courtesy: it is a legal requirement and, in many cases, a condition of operating licences or client contracts.

What is at stake when training is not understood

Health and safety legislation in most EU member states, including Portugal's Lei n.º 102/2009, requires that workers receive adequate training in occupational health and safety and that they genuinely understand it. When materials exist only in the company's working language and the workforce includes speakers of English, French, Arabic, Romanian, or any other language, the employer faces two distinct risks: the risk of an accident caused by misunderstanding, and the risk of regulatory non-compliance with the relevant labour inspectorate.

For companies operating across borders, or those with subsidiaries and joint-venture partners in other markets, this challenge scales. A subsidiary in Angola or Brazil must meet the same safety standards as the parent company, but in a different linguistic and cultural context. The training materials that work in Lisbon or London will not automatically work in Luanda or São Paulo without careful linguistic adaptation.

Which documents require translation in this context

Health and safety training materials are more varied than they appear at first glance. The list typically includes:

• Safety manuals and safe working procedures (including PPE instructions)
• Safety data sheets (SDS), governed by REACH and CLP regulations
• Emergency response and evacuation plans
• E-learning content and training presentations (PowerPoint, SCORM modules, videos requiring subtitles or voiceover)
• Knowledge assessment tests and compliance questionnaires
• Training records and acknowledgement declarations
• Safety signage and posters

Each format carries its own requirements. An SDS has a structure regulated by REACH and CLP; an e-learning module requires adaptation to the learning management system (LMS) in use; a training video may need subtitling, voiceover recording, or dubbing. Translating these materials is not a straightforward linguistic exercise. It requires technical knowledge of occupational health and safety, standardised terminology, and in many cases a review of compliance with the regulatory requirements of the target country.

Choosing the right level of service

Not every health and safety document demands the same level of rigour. The appropriate service level follows the potential impact of an error.

For critical procedural manuals, safety data sheets, and emergency plans, an error has direct consequences for people's safety. These documents justify a process with independent review and formal quality control, such as the workflow required under ISO 17100. An error in instructions for handling hazardous substances can cost a life or expose the company to serious civil liability.

For general awareness e-learning content or lower-risk internal materials, a process with a qualified linguist and self-review may be sufficient, provided the safety terminology has been standardised and validated beforehand.

For large volumes of reference material or content under development, AI translation with selective human review can process content quickly without compromising the essentials. This level is not appropriate for critical safety instructions.

The correct decision requires mapping each document type to its risk level before selecting a service. Companies that treat all training materials as equivalent to routine administrative documents make a common and potentially costly mistake.

How to prepare materials for efficient translation

Translation quality and turnaround time depend heavily on how documents are delivered. Several practices reduce both cost and lead time:

• Provide files in editable formats (Word, PowerPoint, InDesign, SCORM source files) rather than scanned PDFs
• Share any terminology glossaries already approved by the health and safety department
• State clearly the target country and the audience profile (literacy level, professional sector)
• Flag any country-specific regulatory requirements in the target market
• Consolidate all target languages into a single request to support terminological consistency across the project

Organisations without prior experience in translating health and safety content tend to underestimate the importance of a validated glossary. Terms such as "personal protective equipment", "lockout/tagout", or "exposure limit value" have precise equivalents in each language that must remain consistent across every document in the set.
