Managing Multilingual Maintenance Teams: Communication That Works

Your maintenance team speaks four languages. Work orders come in English. Safety training assumes everyone understands technical terminology. And somehow, you’re expected to keep equipment running and everyone safe.

This is reality for facilities managers across Southeast Asia, the Middle East, and increasingly in Western countries with diverse workforces. Language barriers don’t just create inconvenience—they create safety risks, quality issues, and team friction.

Here’s how to build maintenance operations that work across languages.

The Multilingual Maintenance Reality

Workforce Demographics

According to ABLEMKR’s construction staffing research:

In 2022, foreign-born workers made up 28.3% of the U.S. construction workforce. Unfortunately, these workers are at a higher risk for injuries, with 792 fatalities among Hispanic or Latino workers recorded across all industries that year, 316 of which occurred in construction.

In Southeast Asia and the Middle East, multilingual workforces are the norm, not the exception. Singapore facilities commonly employ workers speaking English, Mandarin, Malay, Tamil, Thai, and more. Gulf states rely heavily on workers from South Asia, the Philippines, and other regions.

The Safety Impact

According to Construction Management UK:

Multilingual sites often encounter specific challenges regarding safety, integration and productivity. Workers from a non-English-speaking background are at a higher risk of accidents than their local counterparts. Considering migrant workers comprise up to 50% of the onsite workforce in London, and many of these workers speak little or no English, the size of the issue is considerable.

The numbers are clear:

• Companies with strong language support see 28% fewer communication issues
• Safety incidents reduce by 25% when workers understand protocols in their native language
• Productivity improves when instructions are clear

The Hidden Burden

According to IVANNOVATION’s multilingual project research:

On a daily basis, migrant workers often find themselves involved in interpreting/translating between their first language and English to help facilitate communication with their peers in an ad-hoc and informal manner. Although these bilingual workers are key to the everyday functioning of sites, their role is not formally recognized.

Your bilingual team members are doing translation work on top of their actual jobs—unpaid, untrained, and with no quality verification. When the information involves safety, this informal system is dangerous.

Communication Strategies That Work

1. Visual-First Work Orders

The most effective communication transcends language barriers entirely.

Photo-based work orders:

Element	Purpose
Problem photo	Shows exactly what needs attention
Location photo	Confirms where to go
Expected outcome photo	Shows what “done” looks like
Parts photos	Identifies correct components

Work order systems with photo capability enable technicians to understand tasks even with limited language proficiency.

Visual checklists:

• Use icons alongside text
• Include reference images for each step
• Show correct vs. incorrect examples
• Minimize reliance on written instructions

2. Native Language Interfaces

Machine translation isn’t enough. True multilingual support means:

Feature	Machine Translation	Native Support
Menu navigation	Often awkward	Natural flow
Technical terms	Frequently wrong	Contextually accurate
Input method	May not support	Proper keyboard/input
Cultural context	Lost	Preserved
User confidence	Low	High

When evaluating CMMS, ask:

• Which languages have native interfaces (not just translated)?
• Can users switch languages on the same account?
• Are notifications sent in user’s preferred language?
• Do reports generate in multiple languages?

3. Standardized Task Codes

Create a coding system that works across languages:

Example task codes:

Code	English	Chinese	Thai
PM-HVAC-01	Replace air filter	更换空气过滤器	เปลี่ยนไส้กรองอากาศ
PM-PLUM-01	Check for leaks	检查泄漏	ตรวจสอบรอยรั่ว
EM-ELEC-01	Power outage response	停电响应	ตอบสนองไฟฟ้าดับ

When technicians see “PM-HVAC-01,” they know exactly what’s expected regardless of which language the work order is written in.

4. Safety Communication in Native Languages

Safety is non-negotiable. According to Yourco’s workplace communication research:

When workers understand safety protocols in their native language, accidents are less likely to happen – reducing incidents by 25%.

Safety communication requirements:

Document	Language Requirement
Safety training	Full native language delivery
Emergency procedures	All workplace languages
Equipment warnings	Visual + multiple languages
Incident reporting	Native language option
Safety meetings	Translation available

Never assume safety information “gets through.” Verify understanding.

5. Supervisor Communication Training

According to Workplace Languages:

In a multilingual workplace, where employees may also come from different cultural backgrounds, communication challenges are often compounded by language barriers and differing expectations around how information is shared.

Train supervisors to:

• Use simple, direct language (avoid idioms, jargon)
• Confirm understanding through demonstration, not just “do you understand?”
• Recognize cultural communication differences
• Leverage visual aids consistently
• Create psychological safety for questions
• Identify when professional translation is needed

Language-related incidents	Zero	Communication effectiveness
Safety training completion by language	100%	Training accessibility
Near-miss reporting across languages	Increasing	Psychological safety to report
Safety meeting attendance	>95%	Engagement across languages

Operational Metrics

Metric	Target	Indicates
Work order clarification requests	Decreasing	Clear initial communication
First-time fix rate	Increasing	Understood instructions
Work order completion time variance	Decreasing	Consistent understanding
Photo attachment rate	>80%	Visual communication adoption

Team Metrics

Metric	Target	Indicates
Team satisfaction by language group	Equal across groups	Inclusive environment
Promotion rate by language group	Proportional	Fair opportunity
Turnover by language group	Equal or lower	Retention of diverse talent
Informal translation burden	Decreasing	System handling communication

Common Mistakes to Avoid

1. Relying on Machine Translation Only

Google Translate fails for technical terms. “Replace the diffuser” might become nonsense in another language. Native interfaces and standardized terminology matter.

2. Assuming English Proficiency

Workers may nod when they don’t understand. Use demonstration to verify comprehension. Create safe space for questions.

3. Burdening Bilingual Workers

Your Mandarin-speaking technician shouldn’t be the unofficial translator for half the team. Formalize translation support or use systems that handle it.

4. One-Language Safety Training

Safety training in English only when 30% of your team speaks Thai is negligence. Provide native-language safety instruction.

5. Ignoring Cultural Communication Styles

Direct questions may not get honest answers in some cultures. Learn your team’s communication patterns and adapt your approach.

Building an Inclusive Maintenance Team

Language inclusion isn’t just operational—it’s about respect and opportunity.

Recognition:

• Acknowledge the value of multilingual skills
• Recognize informal translation contributions
• Create pathways for language-diverse workers to advance

Development:

• Offer language training (both directions)
• Provide technical vocabulary development
• Create mentorship across language groups

Environment:

• Post signage in all major languages
• Celebrate cultural diversity
• Address language-based discrimination immediately
