The Evolution of Fire Risk Assessment

Fire risk assessments are crucial in mitigating the risk of fire in buildings and ensuring   the safety of occupants. This article explores the evolution of fire risk assessment, highlighting key legislation, guidance documents, including the Building Safety Act 2022, particularly Section 156. Understanding these developments helps illustrate how fire risk assessments have become more sophisticated and comprehensive over time, adapting to changing societal needs and expectations.

Historical Context

The origins of formal fire safety assessments can be traced back to the early 20th century, stemming from the need to address frequent and devastating fires in urban settings. The tragic events of the 1970s, such as the explosion at the Ronan Point tower block in London in 1968 and the King’s Cross fire in 1987, underscored the inadequacies of existing safety measures and spurred legislative reform.

In the UK, the Fire Precautions Act 1971 marked a significant legislative milestone. It mandated the need for fire safety measures in certain premises, laying the groundwork for risk assessment. The act required that any business or organisation with premises take steps to minimise fire risks and protect occupants.

The Regulatory Framework

Over the decades, the regulatory framework surrounding fire safety has evolved significantly. Key legislative highlights include:

1. The Fire Precautions Act 1971: One of the first laws that mandated fire safety measures in the workplace, requiring employers to carry out fire risk assessments.
2. The Fire Precautions (Workplace) Regulations 1997: introduced requiring business that did not need a fire certificate to conduct a fire risk assessment. These regulations broadly bought UK legislation into line with much of Europe. Then in December 1999, the Fire Precautions Regulations were amended. The amendment broadened the scope of the legislation to include businesses that had a fire certificate.
3. The Regulatory Reform (Fire Safety) Order 2005 (RR(FS)O): This legislation shifted the focus from prescriptive measures to a risk-based approach, requiring “responsible persons” to conduct fire risk assessments and implement appropriate preventive measures.
4. The Fire Safety Act 2021: This act clarified that fire safety regulations apply not only to common areas of buildings with multiple dwellings but also to the individual units themselves. It places greater emphasis on risk assessment for a wider range of premises.

These legislative changes reflect a growing understanding of fire safety as a critical aspect of public health and safety, integrating fire risk assessments into building management systems and operational procedures.

A transition in guidance, from PAS 79 to BS 9792

Introduced in 2005, PAS 79 (Parts 1 and 2) was a publicly available specification that set out comprehensive guidelines for conducting fire risk assessments. Before the withdrawal of Part 1 in 2021, it represented a significant evolution in fire safety practices by emphasising a systematic approach to risk evaluation As industry practices evolve, the development of BS 9792 is underway, intended to replace PAS 79-2. This new standard will incorporate updated methodologies and best practices in risk assessment including:

1. Adaptation to Changing Environments: BS 9792 is expected to address the contemporary challenges posed by modern building designs and technologies.
2. Integration with Other Safety Management Systems: The new standard will likely promote the integration of fire safety risk assessments with other health and safety management systems, creating a more holistic approach to building safety.
3. Focus on Training and Competence: BS 9792 will emphasise the importance of the competence of assessors, recognising that well-trained professionals are vital for accurate and effective risk assessment.

Impact of BS 9792 on Fire Risk Assessment Practices

The transition from PAS 79 to BS 9792 is expected to provide a significant advancement in fire risk assessment methodologies. By adopting more comprehensive, forward-thinking practices, BS 9792 will likely raise the standard of fire safety across various sectors and enhance overall building safety culture.

The Impact of the Building Safety Act 2022

The Building Safety Act 2022 introduced crucial reforms intended to improve building safety standards, particularly in high-rise residential buildings. Among its provisions is Section 156, which places an obligation on relevant persons to consider the fire safety of their buildings as part of their overall safety management system.

Key Features of Section 156 of the Act

Section 156 of the Building Safety Act 2022 significantly enhances the evolution of fire risk assessment by mandating accountability among duty holders for fire safety in all buildings covered by the RR(FS)O. It reinforces a comprehensive approach to identifying and mitigating fire risks, ensuring that fire safety measures are meticulously integrated into building management practices. This legislation underscores the importance of ongoing assessments, reflecting a shift toward more proactive and responsible fire safety management.

The Act represents a significant shift toward a more proactive approach to building safety and fire risk management, with legal repercussions for neglecting fire safety responsibilities. This evolution is part of the broader movement to ensure that buildings are not only designed safely but are also actively managed to maintain those safety standards.

Integrating Fire Risk Assessment into Building Management Practices

As fire risk assessments have evolved, they have increasingly been integrated into broader building management systems. This integration is essential for ensuring that fire safety considerations are embedded in the entire lifecycle of a building—from design and construction to operation and management.

Risk-Based Decision Making

Modern fire risk assessments should inform risk-based decision-making processes, allowing building operators to prioritise safety resources effectively. They take into account various factors, including:

• Occupancy Type: Different types of occupancy present distinct fire risks (e.g., residential vs. commercial).
• Building Materials: The materials used in construction can significantly influence fire spread and duration.
• Fire Safety Systems: Assessors evaluate the effectiveness of installed fire safety measures, such as alarms, sprinklers, and emergency exits.

Technological Advancements

In addition to evolving legislation and standards, technology has played a significant role in improving fire risk assessments. The advent of smart building technologies offers opportunities for more precise monitoring and management of fire safety.

1. Smart Buildings: Modern ‘smart’ buildings can integrate fire alarm systems with other safety systems, allowing for real-time monitoring of conditions that may indicate a fire risk, such as smoke detection or unusual temperature changes. This integration can provide a comprehensive overview of building safety and allow for faster response times
2. Data Analytics: Data collected from various sources (e.g., fire alarms, occupancy sensors) can be analysed to predict potential fire risks more accurately. Predictive analytics can help identify patterns and vulnerabilities within the building, allowing for preemptive actions to mitigate risks.

Challenges in Fire Risk Assessments

Despite the improvements in fire risk assessment methodologies, several challenges persist. Understanding and addressing these challenges is crucial for continued development in fire safety practices.

1. Complexity of Buildings: Today’s buildings are often complex, featuring intricate designs and multiple levels of use. Assessing fire risks in such environments can require a significant investment of time and expertise. Knowledge of various materials, building codes, and potential fire hazards is essential.
2. Competence: One of the major issues raised by the Grenfell Tower Inquiry Report was the lack of competence across the sector. Competence in building management is addressed in PAS 8673, whilst competence of fire risk assessors will be addressed in the forthcoming PAS 8674.
3. Stakeholder Communication: Effectively communicating fire safety information across multiple stakeholders (e.g. building owners, management teams, fire safety officers, and residents) can be challenging. Ensuring that everyone involved understands their roles and responsibilities regarding fire safety is essential for successful risk management.

Future Trends in Fire Risk Assessment

The future of fire risk assessment is set to evolve further, reflecting changing societal expectations and technological advancements. Anticipated trends include:

1. Increased Regulatory Pressure: As the Government becomes more aware of the importance of fire safety, we can expect more stringent regulations and standards imposed. This trend will likely place greater emphasis on the importance of comprehensive fire risk assessments and accountability for those responsible for building management including the selection of fire risk assessor from a nationally recognised competence scheme.
2. Comprehensive Fire Risk Assessments: The provision of Section 156 of the Building Safety Act 2022 mandates that fire risk assessments must consider the specific fire safety needs of all buildings in scope of the RR(FS)O. This includes evaluating fire escape routes, fire alarm systems, and the adequacy of firefighting access. By emphasising comprehensive assessments, Section 156 seeks to ensure that all potential fire hazards are identified and addressed adequately.
3. Emphasis on Sustainability: Fire safety will increasingly intersect with sustainability concerns. As buildings integrate more sustainable materials and designs, fire risk assessments will need to adapt to evaluate the unique risks associated with these innovations.
4. Focus on Mental Health and Wellbeing: There is a growing recognition of the role that fire safety can play in the mental health and wellbeing of occupants. Ensuring safe evacuation routes, minimising fire hazards, and providing a sense of security are all essential considerations in modern fire risk assessments.

Conclusion
