Short answer

Prioritize the design of evacuation systems and plans that mitigate the effects of stress and cater to a wide range of individual characteristics, especially for vulnerable populations.

Field: Human Factors
Source: Journal of Occupational Health and Epidemiology (2025)
Method: Systematic Review
Evidence: Strong effect

During building fires, an individual's stress levels and personal characteristics are the most critical human factors impacting their evacuation behavior and decision-making. This human factors research insight is drawn from a 2025 study published in Journal of Occupational Health and Epidemiology. Using Systematic review, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize the design of evacuation systems and plans that mitigate the effects of stress and cater to a wide range of individual characteristics, especially for vulnerable populations.

Stress and Personal Characteristics Significantly Influence Emergency Evacuation Behavior

During building fires, an individual's stress levels and personal characteristics are the most critical human factors impacting their evacuation behavior and decision-making.

Journal of Occupational Health and Epidemiology · 2025

Key Findings

01Six critical categories of human factors affect emergency evacuations: demographic/physiological parameters, supportive evacuation tools, individual capabilities, stress/personal characteristics, human behavior, and emergency response plans.
02Stress and personal characteristics were the most frequently discussed factors influencing evacuation behavior and decision-making.

Application

Design takeaway

Prioritize the design of evacuation systems and plans that mitigate the effects of stress and cater to a wide range of individual characteristics, especially for vulnerable populations.

How to apply

When designing any system involving emergency response or high-stress situations, conduct user research that specifically probes how stress and individual differences affect behavior and decision-making.

Project actions

01When researching human behavior in your design project, consider how stress might affect your target users.
02Think about how to make your design clear and easy to use even when someone is panicked.

Method & Evidence

AimWhat are the primary human factors that influence emergency evacuation behavior during building fires?

MethodSystematic Review

ProcedureA systematic search of academic databases (PubMed, Science Direct, Google Scholar) was conducted for articles published between 2010 and 2022. Studies were screened and assessed for quality, with 34 studies meeting the inclusion criteria. The findings were then categorized and analyzed.

ContextEmergency evacuations during building fires

Variables

IV["Stress levels","Personal characteristics (e.g., age, health, experience)"]

DV["Evacuation behavior","Decision-making processes"]

CV["Building type","Fire scenario details","Demographic parameters (though also an IV)"]

Strengths & Limitations

Strengths

+Comprehensive systematic review methodology.
+Categorization of multiple human factors provides a structured overview.

Limitations

It can be challenging to accurately measure stress levels in real-time or to ethically induce stress for experimental purposes in a design project.

Reliability & validity

The systematic review's strength lies in its rigorous methodology for synthesizing existing research, enhancing reliability. Validity is supported by the PRISMA guidelines and quality assessment of included studies.

Think critically

How can designers proactively design for stress reduction in emergency situations, rather than just reacting to its effects?

Design Principles

"Design for human resilience under duress by simplifying choices and providing clear, actionable guidance during emergencies."

Understanding how stress and individual traits affect people's actions during emergencies is crucial for designing more effective evacuation systems and protocols. This knowledge allows for the creation of targeted strategies that account for diverse human responses, potentially saving lives and reducing losses.

What This Means for Your Design

When people are stressed during a fire, their personality and how stressed they are really change how they act and what they decide to do when trying to get out of a building.

How to use in your project
