Gasoline safety is essential on any job site where fuel is used. Its flammable vapors and health risks make proper handling, storage, and use critical to preventing fires and injuries.
Gasoline is one of the most common fuels used on job sites, powering vehicles, generators, and other essential equipment. However, despite how routine its use may seem, gasoline is also one of the most dangerous substances when improperly handled. Each year, gasoline-related incidents result in injuries, fatalities, and millions in property damage. Understanding the risks, and how to manage them, is critical to maintaining a safe work environment.
The Dangers of Gasoline
The odor of gasoline often serves as the first sign of a hazardous concentration. Its vapors are heavier than air, meaning they tend to collect in low-lying or enclosed spaces. These vapors can also travel long distances and ignite when they reach a heat or flame source, causing a flashback explosion.
According to the National Fire Protection Association (NFPA), gasoline is responsible for around 150,000 fires, 500 fire-related deaths, and more than $450 million in property damage in the U.S. annually.
Health Effects and Hazards
There are many common routes of exposure, including inhalation, skin or eye contact, and ingestion.
Gasoline exposure can cause a variety of short-term and long-term health effects, such as:
- Short-term Exposure to Small Amounts of Gasoline Vapors: Irritation to the nose and throat, headaches, dizziness, nausea, vomiting, confusion, and breathing difficulty
- Inhaling Large Amounts of Gasoline Vapors: Can lead to coma or death
- And, Chronic Inhalation of Gasoline Vapors: Can result in serious and potentially permanent damage, including impaired walking, memory loss, seizures, involuntary eye movements, hallucinations, and more
Overexposure to gasoline fumes can lead to serious symptoms, such as:
- Coughing and breathing difficulty
- Skin rashes or irritation
- Eye irritation or burning
- Dizziness and disorientation
- Numbness or a burning sensation in limbs
- Rapid heartbeat
- Or, nausea or vomiting
If symptoms appear, the individual should move to fresh air immediately. Persistent symptoms require medical attention. In the event of unconsciousness due to inhalation, call 911.
First Aid Measures
Burns from gasoline or its vapors can be severe. The American Burn Association recommends immediate medical attention for burns affecting the face, hands, feet, genitals, or major joints. For minor burns, flush with cool water and cover with a sterile dressing. Do not apply creams, ointments, or ice, and avoid breaking blisters.
For ingestion of gasoline:
- Do not give anything by mouth if the person is unconscious, convulsing, or losing consciousness
- Have them rinse their mouth thoroughly with water
- Have them drink 8 to 10 oz of water
- If vomiting occurs naturally, ensure the victim leans forward to avoid aspiration
- And, administer CPR if necessary and seek emergency medical care immediately
If you believe you have gasoline poisoning, call Poison Control at 1-800-222-1222.
If someone inhales gasoline fumes or vapors, move the person to fresh air immediately and closely monitor their airway, breathing, and pulse. If the person is unresponsive or not breathing, begin CPR right away. Call 911 for emergency medical assistance as soon as possible.
Gasoline Vapors and Ignition
Gasoline vapors are 3 to 4 times heavier than air, allowing them to accumulate in low areas and travel to ignition sources. Because of its low flash point and wide flammable range, even a small amount of vapor can lead to a catastrophic fire or explosion. Always treat gasoline with the same caution you’d give any explosive material.
→ Static Electricity: A Hidden Ignition Risk
In dry or cold weather, static electricity poses a major fire hazard. Fortunately, there are ways to reduce this risk, including:
- Touch a metal part of the vehicle to discharge static
- Avoid re-entering a vehicle while refueling
- Use only approved containers placed on the ground
- Fill containers slowly to reduce static build-up
- Avoid using cell phones while fueling
- And, ground fuel containers before and during refueling
→ Managing Heat and Pressure
As gasoline heats up, vapor pressure increases. This causes more gasoline to vaporize, which, when mixed with air, can become dangerously combustible. Always store and handle gasoline according to safe temperature guidelines to prevent pressure build-up and accidental ignition.
Transporting and Refueling Safety
Transporting gasoline requires special precautions, including:
- Use only approved containers with tightly closed lids
- Place containers in the trunk of the vehicle and leave the trunk ajar for ventilation
- Secure containers to prevent movement
- Never store gasoline containers in a vehicle
- Avoid transporting gasoline in direct sunlight or high heat
- And, transport only short distances
When refueling vehicles or equipment, always set the gasoline container on the ground to reduce the risk of static electricity. Avoid overfilling to allow for fuel expansion, and be sure to keep all open flames and smoking materials far from the refueling area to prevent fires or explosions.
Handling, Storage, and Containers
→ Handling:
Immediately report any leaks or spills. Remove all ignition sources, including sparks, open flames, and hot equipment. Post clear “No Smoking” signs and avoid use near welding operations. All containers and equipment must be properly grounded and bonded.
→ Storage:
Store gasoline in a cool, dry, well-ventilated area away from sunlight, heat sources, and workspaces. Use minimal quantities in storage, and always ensure containers are bonded and grounded. Ground clips must make contact with bare metal.
→ Containers:
Only use containers that are approved and specially designed to safely store gasoline. Non-approved containers are unsafe and not permitted as they pose a high risk for leaks, fires, and explosions.
Personal Protective Equipment (PPE)
When handling gasoline, proper PPE is essential, including:
- Chemical-resistant gloves
- Safety glasses or goggles
- Flame-resistant clothing
- And, respirators, such as an N95 mask
Conclusion: Safety Starts with Awareness
Gasoline is a powerful and dangerous substance. While it fuels much of our daily work, it also poses significant hazards when used carelessly. Workers must remain vigilant about proper storage, transport, handling, and use. Always report unsafe conditions—whether it’s a leaking container, poor labeling, or unsafe refueling practices—to your supervisor immediately. With the right precautions, we can keep every job site safe and prevent gasoline-related injuries and accidents.
