On World Day for Safety and Health at Work, the focus often centres on policies, procedures and high-level awareness.

Across projects in the UAE, Oman and Saudi Arabia, as well as international markets, Tenable FEC applies fire engineering design, fire strategy development, computational modelling and system validation to ensure buildings perform safely under real conditions.

From a fire engineering perspective, workplace safety is defined by something more fundamental: how a building performs under real conditions.

A safe working environment does not just meet regulatory requirements. It is where fire risks are properly identified, mitigated and managed, and where systems operate as intended when they are needed most.

It also considers how occupants actually use the space day to day, how the building operates in practice, and how systems will perform under realistic emergency conditions.

In practice, this means ensuring occupants can evacuate safely, emergency responders can access the building effectively, and critical systems such as detection, suppression, smoke control and compartmentation work together as an integrated fire and life safety strategy.

Early Fire Strategy in Workplace Design

One of the most consistent challenges across projects is the timing of fire strategy. Fire and life safety should be considered at the earliest conceptual design stages, before key architectural, structural and MEP decisions are finalised. Early involvement allows fire engineering principles to shape core elements such as:

• Occupancy classification and occupant load assumptions
• Means of egress design and evacuation philosophy
• Fire compartmentation strategy
• Selection of suppression systems
• Smoke control approach
• Emergency response access
• Operational use of the building

Even relatively small planning decisions, such as open atriums, interconnecting stairs, mixed-use spaces or high-density occupancy layouts, can significantly alter fire risk profiles and require more robust mitigation measures.

When introduced too late, fire safety measures are often forced into a design that was never intended to support them. This typically leads to compromise, redesign and increased project risk.

Early fire engineering engagement supports stronger design decisions, reduces programme risk and enables more effective, performance-based outcomes.

Performance-Based Fire Engineering vs Prescriptive Design

In many modern workplaces, prescriptive code approaches alone are not sufficient. The limitations of prescriptive pathways become more apparent in complex or non-standard buildings, including:

• Large open-plan offices
• Buildings with atriums
• High-rise workplaces
• Industrial facilities
• Mixed-use developments
• Facilities with unique operational processes

These environments require a more advanced understanding of how fire and smoke behave, and how occupants respond.

Performance-based fire engineering allows these conditions to be analysed in detail. Through computational modelling and scenario testing, it becomes possible to assess:

• Smoke movement and heat development
• Evacuation dynamics
• System interaction under realistic conditions

This approach enables design teams to develop solutions that reflect how buildings actually operate, rather than relying solely on standard assumptions.

In practice, modelling can significantly influence design outcomes. For example, in complex developments incorporating large atriums, performance-based analysis can demonstrate how alternative smoke control strategies, enhanced detection systems and phased evacuation approaches can achieve equivalent or improved safety outcomes, while preserving the architectural intent.

What a Fire Strategy Achieves in Workplace Safety

A common misconception is that a fire strategy eliminates risk entirely. It is designed to manage and control risk, not remove it.

Its role is to slow fire growth, limit smoke spread, protect escape routes and provide occupants with sufficient time to evacuate safely.

Another common misconception is that once a building receives approval, fire safety is complete. In reality, safety performance depends heavily on installation quality, commissioning, maintenance and operational discipline throughout the life of the building.

Bridging the Gap Between Design, Installation and Operation

Even the most robust fire strategy can be undermined if it is not carried through correctly.

One of the most significant gaps in workplace safety often occurs during construction and operational handover. Systems that are well-designed on paper may not perform as expected if:

• Fire dampers are incorrectly installed
• Smoke control systems are poorly commissioned
• Fire doors are wedged open or not maintained
• Maintenance procedures are weak or inconsistent

Fire and life safety is not achieved at handover. It is maintained through continuous alignment between design intent and operational reality.

Fire Safety System Verification and Performance Validation

At Tenable FEC, fire and life safety is approached as a complete system rather than a series of individual components. Verification occurs through multiple stages, including:

• Design reviews
• Computational modelling
• System coordination reviews
• Witness testing
• Commissioning validation
• Scenario-based assessments

These processes ensure that systems are reviewed not in isolation, but as part of an integrated fire and life safety strategy.

Performance validation often involves witnessing integrated system testing under simulated emergency conditions. This may include verifying whether:

• Smoke extraction activates correctly
• Fire alarms communicate with building systems
• Pressurisation systems maintain escape routes
• Lifts respond appropriately during emergency operation modes

The objective is to ensure that real-world performance matches the original engineering assumptions.

Operational Fire Safety in Buildings

Workplace safety is heavily influenced by how buildings are used and managed on a daily basis. Operational discipline is critical. Key factors include:

• Routine maintenance
• Staff training
• Clear evacuation procedures
• Proper housekeeping
• Managing combustible storage
• Maintaining clear egress routes
• Preventing unauthorised system modifications

Even highly engineered systems can fail if daily operational practices are poor.

There are also common oversights that can significantly compromise fire and life safety if left unmanaged, including:

• Blocking fire exits
• Improper storage in plant rooms
• Disabled alarms
• Poor maintenance records
• Propped-open fire doors
• Changes in occupancy without safety reassessment
• Uncontrolled temporary works

Workplace Fire Safety as a Continuous Commitment

On World Day for Safety and Health at Work, one of the most important considerations is what organisations still underestimate.

Fire and life safety is not a one-time design milestone. It is an ongoing operational commitment that requires alignment between designers, contractors, facility managers and occupants throughout the building lifecycle.

The most resilient organisations treat safety as a continuous operational responsibility rather than a compliance exercise.

At Tenable FEC, our approach focuses on practical performance, not just regulatory approval. By combining code expertise, fire engineering analysis, computational modelling, construction-stage review and operational verification, the goal is not simply to achieve compliance, but to ensure the built environment performs safely for the people who use it every day.
