What Is Safety Culture

Why Safety Culture Evolves Differently Across Organisations

SafetyRatios·27 March 2025·9 min read

Safety culture is an emergent property arising from the interaction of deeply held principles, shared assumptions, prevailing predispositions, and consistent actions that shape how a team or organisation approaches safety.

It reflects how safety is valued through principles, understood through assumptions, perceived through predispositions, and demonstrated through actions across all levels of the workplace.

These elements collectively influence how organisations prioritise safety, respond to risk, and learn from operational experience.

Core Elements of Safety Culture

Principles: The core values that define an organisation’s commitment to protecting people and managing risk.
Assumptions: Underlying beliefs about safety that influence everyday decisions and behaviours.
Predispositions: Attitudes and perceptions that shape how individuals interpret hazards and respond to safety expectations.
Actions: Observable behaviours and decisions that demonstrate how safety priorities are applied in practice.

Safety culture does not exist in isolation. It interacts with broader organisational influences such as leadership culture, operational culture, regulatory expectations, and financial pressures. These interactions constantly shape and reshape how safety is interpreted and applied.

How Safety Culture Evolves

Safety culture evolves through ongoing interactions between people, systems, and external pressures. Some influences strengthen safety behaviours, while others may challenge or weaken them.

Changes often appear first in visible behaviours and workplace practices. Over time, these changes may influence deeper attitudes, assumptions, and organisational values.

Key insight: Safety culture cannot be created solely by leadership statements or policy documents. It emerges through everyday decisions, workplace practices, and the interaction between organisational systems and human behaviour.

Historical Evolution of the Concept

One of the earliest formal definitions of safety culture was introduced by the International Atomic Energy Agency (IAEA) following the 1986 Chernobyl nuclear disaster.

"…that assembly of characteristics and attitudes in organisations and individuals which establishes that, as an overriding priority, nuclear plant safety issues receive the attention warranted by their significance."

Over time the concept evolved to emphasise the integration of safety into an organisation’s broader culture, often described as a Culture for Safety. This perspective recognises that safety performance depends on how strongly safety values are embedded in everyday work.

Subcultures Influencing Safety Culture

Organisations rarely have a single unified culture. Multiple subcultures interact and influence how safety is interpreted and prioritised.

1. Financial Culture

Financial culture influences safety through resource allocation and budgeting decisions. Investment choices reveal how risk prevention is prioritised relative to cost pressures.

2. Innovation Culture

Innovation introduces new technologies and processes that may alter risk profiles. Rapid innovation without adequate safety adaptation can create unforeseen hazards.

3. Operating Culture

Operating culture reflects how daily work is organised and repeated. Strong operational discipline can reinforce safety, while rigid routines may conceal emerging risks.

4. Performance Culture

Performance-driven environments emphasise targets and productivity. When results dominate decision making, safety priorities may be unintentionally weakened.

5. Risk Culture

Risk culture determines how organisations interpret uncertainty and hazard exposure. It influences whether risks are openly discussed, ignored, or normalised.

6. Leadership Culture

Leadership behaviour strongly shapes safety expectations. Visible commitment, consistent decisions, and transparent communication reinforce trust and accountability.

7. Stakeholder Culture

External stakeholders such as clients, partners, and investors influence organisational priorities. Their expectations can either strengthen safety commitments or introduce competing pressures.

8. Regulatory Culture

The way regulators enforce safety laws influences organisational behaviour. Supportive oversight can encourage transparency and learning, while purely punitive environments may discourage open reporting.

9. Media Culture

Media attention shapes how incidents are communicated and perceived. High scrutiny may encourage stronger safety practices but can also drive defensive communication behaviours.

10. National Culture

National values such as hierarchy, collectivism, and communication norms influence how safety is discussed and how authority is exercised in workplaces.

Understanding these interacting subcultures helps organisations recognise why safety culture evolves differently across industries, countries, and organisational structures.
