Why You Should Never Use Petrol Generators at Events
A Crowd & Event Safety Perspective on Petrol Generators at Events from Safe Events Global
Petrol generators at events might seem like a convenient solution for power needs, but when it comes to real-world safety and planning, they introduce serious risks that outweigh any benefits.
At Safe Events Global, we strongly advise against using petrol-powered generators at festivals, concerts, sporting events, and public gatherings.
Here’s why — and what to use instead.
The Dangers of Petrol Generators
Involving specialist Crowd Safety and Event Safety specialists like ourselves – or, indeed, an expert Site Management partner – can help ensure this power consideration is designed in from the start.
1. Fire and Explosion Risk
Petrol is highly flammable, and handling it in active event environments significantly increases the risk of fire.
Spills, unsafe storage, or refuelling near heat sources or smoking areas could lead to severe accidents, including explosions, especially with crowds nearby.
Petrol generators utilise a spark to ignite the fuel. Diesel generators do not.
2. Carbon Monoxide Poisoning
Petrol generators emit carbon monoxide (CO), a colourless and odourless gas that can cause serious injury or death in poorly ventilated areas.
Using them inside or near enclosed spaces such as marquees, trailers, or booths puts staff and attendees at risk of silent, rapid poisoning.
The HSA in Ireland have this advice re carbon monoxide poisoning.
3. Noise Pollution
Petrol generators are extremely noisy, interfering with critical event functions like public address systems, live performances, or team communications.
This noise can diminish the audience experience, especially at wellness-focused, educational, or family-oriented events.
4. Fuel Storage and Transport Hazards
Storing and transporting petrol on site creates multiple risks, including fire hazards, fuel theft, or spills that damage the environment.
Even minor leaks can cause soil or water contamination and may breach environmental or fire safety regulations.
The heat required for petrol to ignite is much lower than that for diesel. This makes petrol generators at events a bad idea.
5. Insurance and Licensing Complications
Many insurers and Local Authorities now demand strict documentation for the use of fuel-powered equipment at events.
Petrol generator use could result in licensing violations, rejected insurance claims, or even shutdowns by Health and Safety inspectors if proper procedures aren’t followed

Safer Alternatives to Petrol Generators
There are much better options than utilising petrol generators at events.
Battery-Powered Units
Modern battery packs provide clean, quiet, and emission-free power for low-draw applications such as vendor lighting, mobile phone charging, signage, or information kiosks.
These systems are portable and sustainable, making them ideal for pop-up events or green festivals.
Solar Hybrid Systems
Solar panels combined with battery storage are increasingly viable, particularly for daytime or multi-day events with moderate power needs.
While they may not support heavy loads alone, they significantly reduce diesel dependency and align with sustainability goals.
Stage-Grade Diesel Generators
For larger power demands, high-quality diesel generators remain the most effective option.
These should always be installed and operated by qualified professionals and integrated into a broader power management strategy.
Proper placement, fuel containment, and noise control are essential for safe use.
