Emergency lamp explosion proof in the gas station lighting in the fundamental role and safety application guidelines

Introduction: gas station safety challenges and the inevitable choice of Emergency lamp explosion proof

Gas station as a key node of energy supply, long-term exposure to gasoline vapor [explosion limit of 1.4% -7.6%], potential oil and gas leakage and high static risk environment.

Ordinary lighting equipment once the spark or surface overheating, it is very easy to cause an explosion, threatening the safety of people and property.

Emergency lamp explosion proof with its professional explosion-proof design, emergency power supply function and all-weather weather-resistant performance, into the gas station lighting system core safety equipment.

In this paper, we will analyze the Emergency lamp explosion proof in gas stations in the application scenarios, technical guidelines and implementation strategies for industry users to supply compliance, efficient solutions.

First. A gas station explosion risk and Emergency lamp explosion proof core value

1. The primary safety hazards of gas stations

Explosive environment of oil and gas mixtures: fuel dispenser operations, tank breathing valve release gasoline vapors mixed with air to form Class I, Division 1 [Zone 0/1] hazardous area.

Risk of static electricity accumulation: oil flow, personnel clothing friction generates static voltage up to 10kV or more, ordinary lamps and lanterns shell if not grounded, probably triggering discharge sparks.

Extreme outdoor environment: rain, snow, salt spray erosion and temperature difference between day and night [-30 ℃ ~ +50 ℃] easily lead to aging failure of the lamps.

2. Emergency lamp explosion proof safety protection mechanism

Emergency light explosion proof approved the following technology to implement intrinsic safety:

Explosion-proof structure [Ex d] and intrinsically safe circuit: cast aluminum shell inside the explosion-proof cavity to ensure that sparks or high temperature is not leaked; circuit design in line with the Ex ia / Ib guidelines to limit the energy output.

Static dissipation and grounding care: the surface resistance of the lamp body ≤ 1 × 10⁶Ω, with copper grounding terminals, high-speed conductive static electricity.

Emergency power supply high-speed response: 0.25 seconds after the interruption of the main power supply switch to lithium iron phosphate battery, supply ≥ 90 minutes of continuous lighting, in line with the “GB 17945-2010 fire emergency lighting guidelines.

Second, Emergency lamp explosion proof in the gas station in the core application scenarios

1. refueling area and storage tank area

Fuel dispenser status indication: install Emergency lamp explosion proof on the top of the fueling island, integrating red/green dual-color lights, prompting equipment failure [e.g., the fuel gun is not returned to the position of the red light alarm].

Emergency Response to Oil and Gas Leakage: Equipped with gas detection module Emergency lamp explosion proof, triggering audible and visual alarms and emergency lighting when the oil and gas concentration is ≥25% LEL, synchronized with the linkage of the air exhaust system.

2. Emergency evacuation and safe passage

Intelligent Evacuation Guidance System: Deploying direction-indicating Emergency lamp explosion proof at the passages and exits of the station, automatically activating the escape mode in case of fire or gas leakage, with ground illumination ≥5lx and arrows guiding the shortest path.

Anti-glare and smoke penetration: Adopt high color rendering LED [Ra>85] and red filter to ensure that the logo is clearly visible in the smoke environment.

3. Convenience stores and auxiliary areas

Uninterrupted security lighting: convenience store cashier area, distribution room installation of Emergency lamp explosion proof, main power failure to maintain ≥ 50% of the normal illumination, to avoid panic stampede.

Outdoor advertising and signage lighting: Emergency lamp explosion proof with IP68 protective housing, resistant to rainstorms, to ensure that the gas station brand logo visible 24 hours.

Third, the gas station Emergency lamp explosion proof selection and technical guidelines

1. Certification and compliance requirements

Explosion-proof certification: must be approved ATEX [II 2G Ex d IIC T4 Gb], IECEx or China CNEx certification for Class I, Zone 1 [gasoline vapor environment].

Protection level: IP68 [dustproof and waterproof] for outdoor area, at least IP65 for indoor area.

2. Fundamental technical parameters

Light source performance: LED light source light efficiency ≥ 140lm / W, color temperature 4000K-5000K, to avoid UV light to accelerate the volatilization of oil.

Emergency range: According to GB 51309-2018 Fire Emergency Lighting Specification, the refueling area needs to be equipped with Emergency lamp explosion proof with a range of ≥180 minutes.

3. Intelligent function upgrade

IoT remote management: Approve 4G/LoRaWAN real-time monitoring of the status of the lamps and lanterns, battery health and failure warning, reducing the cost of manual inspection.

Multi-sensor fusion: integrated temperature and humidity, gas concentration sensors, data uploaded to the station SCADA system, the implementation of active safety prevention and control.

Fourth, Emergency lamp explosion proof installation and maintenance specifications

1. Specialized installation requirements

Explosion-proof electrical wiring: the use of flame retardant oil-resistant cable [such as CY type], the junction box adopts Ex e increased safety structure, grounding resistance ≤ 4Ω.

Spacing and height improvement: the installation height of lamps and lanterns in the refueling area is ≥4 meters, with a spacing of 6-8 meters to ensure that the horizontal illuminance is ≥100lx [the operating surface of the fuel dispenser].

2. Lifecycle maintenance strategy

Monthly inspection: Clean the oil on the surface of the lamp body (use anti-static rags), test the emergency switching function and battery capacity (charge after discharging to 50%).

Annual professional inspection: entrust the explosion-proof certification body to test the gap between the flameproof surface [≤0.1mm], insulation resistance [≥1000MΩ] and shell impact resistance [IK10].

Fifth. Answers to common problems [FAQ].

Q1：All areas of the gas station are required to Emergency lamp explosion proof?

A: 6 meters around the fuel dispenser [Zone 1], near the tank vent [Zone 0] must be used; convenience stores and other non-hazardous areas can be configured with ordinary emergency lights, but need to be physically separated from the hazardous area.

Q2：Emergency light explosion proof emergency response time how to limit?

A：Safety lighting needs to start within 0.5 seconds, evacuation lighting ≤ 5 seconds, in line with GB 17945-2010 guidelines.

Q3：How to prevent gas station lamps and lanterns from exploding due to static electricity?

A: Select surface resistance ≤ 1 × 10⁶Ω Emergency lamp explosion proof, and strictly grounded [grounding wire cross-sectional area ≥ 4mm ², resistance ≤ 4Ω].

Q4：How long is the battery life of Emergency light explosion proof?

A: lithium iron phosphate battery cycle times ≥ 2000 times [about 5-7 years], advocating the implementation of capacity testing every 2 years, below the nominal value of 80% replacement.

Conclusion: Emergency lamp explosion proof – gas station safety operation “lifeline”!

In the gas station safety management guidelines are increasingly strict today, approved the deployment of high standards explosion-proof emergency lighting system, enterprises can effectively avoid the risk of explosion, enhance the emergency response capabilities.
