Plastic gas containers should have flame arresters
Plastic gas containers can explode, causing serious injury, loss of life, or property damage. Gasoline is highly flammable, and its vapours can accumulate inside the container or in the surrounding area, especially if the container is not sealed properly or exposed to heat. Heat is one of the biggest triggers for gas can explosions. When a plastic can is exposed to high temperatures, the gasoline inside begins to vaporize, increasing pressure inside the container. This can lead to a dangerous pressure buildup, which, in combination with a spark or flame, can cause an explosion.
To mitigate this risk, plastic gas containers should be equipped with flame arresters, a simple and inexpensive safety feature. Flame arresters are small pieces of metal mesh installed in the spout of the container. They are designed to block flames from travelling back into the container and igniting the vapours while allowing gas to pour out. This safety mechanism has been known for over 100 years and is found in various applications, including Bacardi Rum bottles. By blocking the flames, flame arresters prevent explosions and enhance the overall safety of gasoline storage and handling.
The absence of flame arresters in plastic gas containers has sparked litigation and raised concerns among consumers. Manufacturers have often prioritized cost-saving over safety, choosing not to include flame arresters to save a minimal amount per container. This decision has had severe consequences, with thousands of adults and children suffering burns, injuries, and even fatalities from gas can explosions. The addition of flame arresters is a crucial step towards ensuring the safe use and storage of gasoline, especially in plastic containers, which are more susceptible to heat-induced explosions.
It is important to note that while flame arresters provide a layer of protection, they do not eliminate all risks associated with gasoline storage. Proper storage conditions, such as avoiding direct sunlight and ensuring tight closures, are still essential. Additionally, gasoline should only be stored in containers specifically designed for gasoline, as general-purpose plastic containers may not have the necessary ventilation to prevent vapour buildup and may be susceptible to chemical breakdown by gasoline. Consumers should prioritize their safety by opting for gas containers with flame arresters and other safety features, such as child-proofing and spill-proofing mechanisms. By taking these precautions, the risks associated with gasoline storage in plastic containers can be significantly reduced.

Gasoline vapours can cause combustion
Gasoline is a highly flammable liquid with a flashpoint of -45ºF (-43ºC). It is so flammable that even its vapours can ignite, causing combustion. Gasoline vapours can accumulate inside the container or in the surrounding area, especially if the container is not sealed properly or is exposed to heat. Heat is one of the biggest triggers for gas can explosions. When a plastic or metal can is exposed to high temperatures, the gasoline inside begins to vaporize, and these vapours increase pressure inside the can. This can lead to a dangerous pressure buildup in a sealed environment like a closed garage or the trunk of a car.
The vapours can also be ignited by static electricity or mechanical sparks. For instance, when refueling equipment or pouring gas from one container to another, any small static discharge could ignite the vapour cloud. Even simple movement of gasoline inside a plastic container can generate static electricity. Therefore, it is crucial to avoid uneven surfaces, lined truck beds, and carpeted car floors when filling a gas container.
To prevent explosions, gasoline containers should have flame arresters, which are small pieces of metal mesh installed in the spout. They block flames from travelling back into the container and igniting the vapours while allowing gas to pour out. Despite their low cost, many manufacturers choose not to include flame arresters in their gas can design to save money. This has led to a flurry of litigation related to plastic gasoline containers exploding over the past decade.
To store gasoline safely, use containers specifically manufactured for gasoline storage, such as Type I and Type II Safety Cans. These containers can be made of plastic or metal but are always fortified with safety features. Proper plastic gas cans are usually made of thick, reinforced HDPE. Common HDPE containers like milk jugs are not suitable for gasoline storage as they risk becoming soft over time and do not offer the necessary ventilation to eliminate fire hazards. Steel drums are another option for gasoline storage as they are extremely durable and less likely to interact with flammable chemicals.

Gasoline containers should be child-proof
Gasoline containers can explode, combust, or catch fire if the vapours are introduced to a heat source, such as an open flame or fire. Gasoline is a highly combustible liquid, and if it combusts, it can lead to serious injury and even death. Therefore, it is essential to take precautions when storing and handling gasoline, especially when children are present.
While undisturbed gasoline in a closed plastic container is unlikely to explode, the risk of an accident increases significantly if the vapours come into contact with a heat source. To mitigate this risk, it is crucial to prioritize child-proofing gasoline containers. Child-resistant packaging has proven effective in preventing children from accessing harmful substances, and its implementation in gasoline containers can provide an additional layer of safety.
In recognition of the dangers posed by gasoline containers, the Consumer Product Safety Commission (CPSC) mandated safety caps that are challenging for children to open. This mandate marked a significant step towards enhancing the safety of gasoline containers. However, it is worth noting that this safety measure alone may not be sufficient. The addition of flame arresters, which are inexpensive safety features, can further reduce the risk of explosions.
To ensure the highest level of safety, gasoline containers should incorporate both child-resistant packaging and flame arresters. Child-resistant mechanisms can prevent children from easily opening the containers, while flame arresters act as a secondary defence by preventing flames from entering the container even if vapours are ignited. This dual approach can significantly reduce the risk of accidents and provide peace of mind to parents and caregivers.
Manufacturers of gasoline containers have a responsibility to prioritize safety over cost-cutting measures. While it may be tempting to forgo safety features to reduce expenses, the potential consequences of an accident far outweigh any monetary savings. By investing in child-proofing and flame-arresting technology, manufacturers can help prevent injuries and save lives. It is imperative that industry regulations and government standards continue to emphasize the importance of child-proofing in gasoline container design, holding manufacturers accountable for the safety of their products.
