Fire mitigation for renewables on petrol stations is crucial as more sites adopt technologies like solar PV, EV chargers, and battery systems. These innovations bring clear sustainability and economic benefits. However, they also introduce unique complexity for fire mitigation and demand specific emergency responses in this high-risk environment.
Therefore, petrol station retailers must fully understand these challenges and understand how renewable energy systems interact with their forecourts. They need to prioritise informed system design, certified installations, and effective emergency planning. By taking these steps, they can ensure safety and operational continuity, while not being excluded from enjoying the advantages of renewable energy.
Understanding Electrical Fire Hazards on Petrol Station Forecourts
Electrical systems are widely recognised as potential fire hazards. Faulty wiring, overloaded circuits, short circuits, loose connections, and arcing faults can generate heat and sparks. Without proper mitigation, even a small spark, or other ignition source, can escalate under certain conditions into a significant fire or explosive hazard. Petrol station forecourt retailers are well-acquainted with these risks and their seriousness on petrol stations. Yet, they can take reassurance from the fact that they know how to mitigate these.
Keep Calm and Mitigate
It is no surprise that UK regulations focus on safety at petrol stations. To achieve this, regulations mandate thorough risk assessments[1]. These assessments not only identify hazards but also highlight those specifically linked to electrical equipment. Once hazards are identified, retailers must carefully evaluate the associated risks. Next, they are required to implement effective control measures. By doing so, fire mitigation on petrol stations can meet safety standards while reducing risks to acceptable levels.
The good news is that fire mitigation on petrol stations can effectively reduce risks. With the right measures in place, these risks can be managed to maintain safety at acceptable levels and protect business operations.
Fire Prevention Strategies on Petrol Stations
Mitigation by design
Fire mitigation on petrol stations adheres to stringent safety regulations designed to reduce hazards. For instance, hazardous areas are classified into zones (0, 1, and 2) based on the likelihood of explosive atmospheres. Only explosion-proof (ATEX-certified) equipment is permitted in these areas.
To prevent sparks, pumps and nozzles on fuel dispensers are carefully designed. Additionally, electrical panels, wiring, and lights are sealed to avoid exposure to flammable vapours.
Proper grounding and bonding of equipment is essential to prevent static discharge. Furthermore, all electrical installations must comply with British Standard BS 7671 and undergo regular inspections.
In emergencies, accessible fireman switches are crucial. These switches allow all power to fuel dispensers to be cut immediately, ensuring safety during critical situations.
The above requirements align with the APEA’s “Blue Book,”[2] which is the authoritative technical guidance for health and safety on petrol station forecourts. Its recommendations are considered the benchmark standard.
Competent Contractors
Petrol station retailers must rely on competent contractors to install and inspect electrical systems.[3]
To meet these standards, electricians can hold an approved and up-to-date City & Guilds Level 3 in Electrical Installations (or an equivalent qualification). Alternatively, they can provide certification body validation as proof of their competency. Membership in a recognized professional body, such as NICEIC[4], can offer additional reassurance. This ensures that work is performed to a high standard and complies with industry requirements.
Electricians should also understand the unique challenges of working in hazardous environments like petrol stations. There are specific qualifications that enable electricians to demonstrate their ability to work safely in explosive atmospheres. One such qualification is the CompEx (Ex07-Ex08) certification.
Additionally, it is a common industry standard for contractors working on petrol stations to hold a SPA[5] Petrol Retail Passport. This was developed in collaboration with Fuels Industry UK[6] and ensures that contractors consistently meet all necessary safety and competency requirements. By adhering to these standards, petrol station retailers can have confidence in the skills and preparedness of these certified professionals.
Emergency Preparedness for Fire on Petrol Stations
So, proper installation and maintenance are essential for effective fire mitigation on petrol stations. These measures play a significant role in preventing fires. However, petrol station forecourt retailers must also focus on emergency preparedness to handle potential incidents effectively.
This preparedness involves emergency planning, training, and, when required, swift implementation. For example, retailers should develop a detailed Emergency Plan (EP) that outlines specific steps to follow during a fire. This plan should include fire detection strategies, evacuation procedures, fire suppression methods, communication protocols, and emergency shutdown actions.
In addition to these steps, clear communication with local fire and rescue services is vital. These services should be familiar with site-specific hazards, the location of fire switches, and emergency access points. By establishing strong lines of communication, retailers can ensure quick and effective responses during emergencies.
So, by combining proper installation, maintenance, and emergency preparedness, retailers can significantly enhance safety. Together, these measures ensure that electrical systems on petrol stations remain secure and compliant with safety standards.
Risk mitigation for renewable energy electrical systems
As well as the complexities of general electrical systems on petrol stations, there are some installations that have unique features that require additional consideration for risk mitigation and the emergency response. These include renewable energy technologies such as EV chargers, solar PV, and battery storage systems.
For example, EV chargers on petrol stations often operate with their own power supply. However, it is essential for the main site fire switch to also cut power to these devices during emergencies. This requirement introduces electrical complexity. Similarly, solar PV systems pose unique challenges because they continue generating electricity in sunlight, even during a full site shutdown. Specific isolation measures are necessary to manage this risk effectively.
No need to throw business out with the bathwater
Despite these challenges, fire mitigation for renewables on petrol stations can be managed effectively. This means that retailers need not be excluded from the benefits these technologies bring. As with other general electrical systems, proper planning and maintenance allows retailers to integrate these systems safely while enhancing sustainability.
