Foreign Language Worker Communication

Subcontractor & Supply Chain Safety › Specific › Foreign Language Worker Communication

Presenter		Project
Location		Date

Construction sites in the UK employ workers from many countries who may not speak or read English fluently.
Language barriers prevent workers from understanding safety briefings, signs, instructions, and emergency procedures.
CDM 2015 requires information and instruction to be provided in a form that workers can understand and act upon.
Site inductions, toolbox talks, and method statement briefings must be adapted for workers with limited English.
Visual aids including photographs, diagrams, pictograms, and colour coding communicate hazards without relying on text.
Translated safety documents in the worker's first language should be provided for critical procedures and emergency plans.
Bilingual supervisors or buddy systems pair experienced English-speaking workers with colleagues who need language support.
Understanding must be verified — nodding does not confirm comprehension, so ask workers to explain back in their own words.
Emergency procedures must be understood by everyone — a worker who does not understand the fire alarm cannot evacuate safely.
Investing in communication removes the language barrier that contributes to the higher injury rate among migrant construction workers.

Prevent misunderstanding	A worker who does not understand the method statement cannot follow it safely — communication prevents the incidents caused by confusion.
Legal duty	CDM 2015 requires comprehensible information — delivering briefings only in English to non-English speakers fails this duty.
Higher injury rates	Research shows migrant workers have higher injury rates partly due to language barriers — effective communication closes this gap.

Don't

Assess the language needs of the workforce at the start of every project.
Provide site inductions with visual aids, diagrams, and translated key information.
Use pictograms, photographs, and colour coding on site signs and safety notices.
Translate critical documents including emergency procedures into workers' first languages.
Assign bilingual buddies or supervisors to support workers with limited English.
Verify understanding by asking workers to explain instructions back in their own words.
Ensure emergency procedures are understood by every worker regardless of language.
Use toolbox talk materials that include visual content for non-English speakers.
Provide language training opportunities to help workers improve their English over time.
Treat language support as a safety investment, not an administrative burden.

DON'T deliver safety briefings only in English to a multilingual workforce.
DON'T assume workers understand because they nod — verify comprehension actively.
DON'T rely on text-only signs when the workforce includes non-English readers.
DON'T withhold translated documents — critical safety information must be understood.
DON'T leave non-English-speaking workers without a bilingual buddy or supervisor.
DON'T accept a head nod as proof of understanding — ask them to explain it back.
DON'T allow workers to start work if they have not understood the emergency procedure.
DON'T use complex technical language in briefings when simpler words will communicate clearly.
DON'T dismiss language support as unnecessary — it directly reduces injury rates.
DON'T isolate workers with language difficulties — include them in team safety conversations.
