Technical Lighting for Petrol Stations: ATEX Safety and Operational Efficiency
Lighting at service stations and petrol stations is a critical factor that combines industrial safety, user visual comfort and business profitability. Due to the nature of these spaces, where potentially explosive atmospheres coexist with 24-hour operation, lighting solutions must strictly comply with the EN 12464-2 standard (Lighting of outdoor work places) and carry ATEX certification in hazardous zones, ensuring perfect visibility and a drastic reduction in energy cost (OPEX).
Technical Requirements and Safety in Classified Zones
The lighting design for petrol stations is broken down into areas with differentiated technical requirements, prioritising tightness and safety against flammable vapours:
- ATEX Certification (Explosive Atmospheres): In the immediate vicinity of the dispensers (Zones 1 and 2), the use of luminaires certified to Directive 2014/34/EU is mandatory. These feature flameproof or increased-safety enclosures to prevent any source of ignition.
- Canopy Optics: We deploy wide, symmetric beam optical systems that provide high vertical illuminance. This facilitates reading the dispensers and handling the hoses, eliminating shadows that could compromise safety.
- Chemical and Environmental Resistance: The enclosures must withstand not only the weather (IP66) but also accidental contact with hydrocarbons and lubricants. The use of tempered glass and aluminium bodies with anti-corrosion treatments ensures the integrity of the equipment against impacts (IK10).
- Lumen Maintenance and Reliability: Given the uninterrupted operation, we select components with L80B10 maintenance factors above 70,000 hours, fitted with drivers featuring high surge protection (SPD) to mitigate spikes on the mains supply.
Energy Efficiency and Smart Control
The transition to LED technology in service stations enables savings of more than 70% over discharge technologies (MH/HPS), optimising the investment through advanced control:
- Time and Sensor Dimming: Integration of programmable drivers that reduce the luminous flux during low-traffic night hours, maintaining safety levels while minimising consumption.
- Microwave Presence Sensors: Activation of 100% power only when a vehicle is detected entering the canopy area, returning to a stand-by level after departure.
- Colour Fidelity (CRI > 80): Improves the perception of safety and aids the correct identification of the corporate image and station signage.
Illuminance Standards by Application Area (EN 12464-2)
| Station Area | Average Illuminance (Em) | Uniformity (Uo) | Comments |
|---|---|---|---|
| Dispenser Area | 150 - 200 lux | ≥ 0.40 | Critical for safety and payment |
| Entries and Exits | 20 - 50 lux | ≥ 0.25 | Visual transition for drivers |
| Shop and Wash Bay | 300 lux | ≥ 0.50 | Commercial and operational focus |
| Circulation Areas | 10 - 20 lux | ≥ 0.25 | Wayfinding light and surveillance |
Frequently Asked Questions (FAQs) on Petrol Station Lighting
Is it mandatory for all luminaires at the petrol station to be ATEX-rated?
Not necessarily. Regulations require ATEX equipment only in zones classified as having a risk of flammable gases or dusts (typically a specific radius around dispensers and tanks). However, beneath the canopy or in access areas, standard high-efficiency industrial luminaires with IP66 protection can be used, provided that the technical safety distances are respected.
How does glare affect safety at service stations?
Poor optical design can cause disability glare for drivers entering from the public highway (where luminance is much lower). Our luminaires use specific reflectors that direct the flux downwards, maintaining glare control that prevents temporary blindness and increases road safety.
What real savings does switching to LED bring at a 24h petrol station?
At a station operating 24/7, the return on investment (ROI) is typically achieved in less than 18 months. In addition to direct savings on the electricity bill, the costs of replacing discharge lamps are eliminated; these suffer very accelerated lumen depreciation and require costly maintenance using lifts under the canopy.
