Plastic gas containers are OSHA-approved and FM-approved
It is important to ensure that your gas cans meet the necessary safety standards. In the US, the Occupational Safety and Health Administration (OSHA) has outlined several requirements for the safe storage and handling of flammable liquids, such as gasoline. These regulations are in place to prevent accidents and improve workplace safety.
OSHA standards specify that only approved containers and portable tanks should be used for storing and handling flammable liquids. For quantities of 5 gallons or less, approved safety cans or Department of Transportation (DOT) approved containers are required. If the flammable material is highly viscous and challenging to pour, it may be exempt from this rule and can be stored in its original shipping container.
To be OSHA-approved, a gas can must meet specific criteria. It should have a capacity of no more than 5 gallons, feature a spring-closing lid and spout cover, and be designed to safely relieve internal pressure during fire exposure. Additionally, the container must be listed by a nationally recognised testing laboratory, such as United Laboratory (UL), to gain approval.
Plastic gas containers that are OSHA-approved can also be FM-approved. FM Global is a company that provides broad risk management solutions, including comprehensive testing and certification services. Their certification indicates that the product meets certain standards for property loss prevention. Justrite, a manufacturer of safety cans and containers, offers a range of OSHA-approved and FM-approved products. These containers are designed to minimise the risk of fires and protect workers by containing hazardous liquids and controlling vapours.

They can expose you to harmful chemicals like lead
Plastic gas containers are a convenient way to store and transport gasoline, and they are also OSHA-approved and FM-approved. However, it's important to be aware of the potential risks associated with using these containers. One significant concern is the exposure to harmful chemicals, such as lead.
Lead is a highly toxic substance that can have severe health impacts. According to the State of California, lead exposure is known to cause cancer and birth defects, as well as other reproductive harm. This warning applies to all plastic gas container products, and it is crucial that users are aware of this potential danger. When using plastic gas containers, it is essential to follow safety protocols and handle them with care to minimize the risk of exposure to harmful chemicals.
The presence of lead and other hazardous chemicals in plastic gas containers is a serious issue. Lead is not naturally occurring in gasoline but is introduced during the refining process. It is added as an octane booster to improve the performance of the fuel. However, when gasoline is stored in plastic containers, the lead can leach out and contaminate the container itself, as well as any surrounding environment. This contamination poses a significant threat to human health, especially for those who come into direct contact with the containers or the gasoline stored within.
To minimize the risk of exposure to lead and other harmful chemicals, it is essential to follow proper safety procedures when using plastic gas containers. This includes wearing protective gear, such as gloves and masks, to reduce direct contact with the containers and gasoline. Additionally, users should ensure that the containers are stored in a secure location, away from children and pets, to prevent accidental ingestion or exposure.
While plastic gas containers offer convenience and durability, it is crucial to prioritize safety and be vigilant about the potential risks associated with their use. By understanding the dangers of lead exposure, users can take the necessary precautions to protect their health and the environment. Proper disposal of plastic gas containers is also essential to prevent further contamination and minimize the impact on the ecosystem. It is always advisable to check with local waste management authorities for specific guidelines on how to responsibly recycle or dispose of plastic gas containers.

Plastic containers are generally categorised by a resin identification code
Plastic containers are generally categorized by a resin identification code (RIC), which is a technical standard with a set of symbols that appear on plastic products to identify the type of plastic resin used in the manufacturing of the product. The RIC system was developed in 1988 by the Society of the Plastics Industry (now the Plastics Industry Association) in the United States. Since 2008, it has been administered by ASTM International, an international standards organization.
The purpose of the RIC is to facilitate the collection, disposal, and recycling of plastic products. The codes help consumers and waste operators distinguish one material from another and sort products more efficiently. While there is no federal regulation mandating the use of RICs, many US states require certain plastic products, such as bottles and rigid containers, to carry them. Each state may have its own requirements, including different number codes for the RICs.
The most commonly recycled plastic is PET, which has the code 1. This material is often used for clear plastic bottles and can be recycled into polyester fabric and filling for fleeces, carpets, and cushions. High-Density Polyethylene (HDPE), with the code 2, is another widely recycled plastic. It is commonly found in milk bottles, shampoo bottles, and cleaning product bottles. Polypropylene (PP), with the code 5, is used for auto parts, industrial fibers, and food containers. Polystyrene (PS), with the code 6, is used for plastic utensils, Styrofoam, and cafeteria trays.
It is important to note that the presence of an RIC on a product does not necessarily indicate that it is recyclable, and consumers should check with their local recycling facilities to see what types of plastic they accept. The Sustainable Packaging Coalition has created a "How2Recycle" label to provide clearer information on recyclability, with four labels indicating whether an item is widely recycled, limited, not yet recycled, or accepted at store drop-off locations.

Polyethylene Terephthalate (PET or PETE) is easily recyclable
Polyethylene terephthalate, commonly known as PET or PETE, is a clear, durable, versatile, and highly recyclable type of plastic. It is widely used in the food, beverage, pharmaceutical, and medical sectors due to its safety, durability, and shatterproof nature. PET is approved for use in direct food contact by the US FDA and health agencies worldwide.
PET is easily recyclable, and its high recyclability makes it less likely to end up in landfills. It can be recycled into its original uses, such as new bottles, and other products like winter jackets, rugs, playground equipment, and dog beds. Recycled PET (rPET) is highly sought after as it reduces the environmental impact associated with creating new plastic. Using rPET to make new bottles reduces total energy consumption by 79% and limits greenhouse gas emissions by 67%.
The recyclability of PET also reduces emissions compared to other materials. For example, producing cans from aluminium requires heating to temperatures above 1000°C, while PET only needs around 260°C. This results in higher emissions for aluminium production. Similarly, glass production and recycling require very high temperatures, leading to up to 4.5 times the emissions of PET bottle production.
PET's lightweight nature further contributes to its environmental benefits. rPET bottles have lower transport emissions than reusable glass bottles since they are much lighter. Additionally, raw paper and cardboard are more biodegradable than PET, but food packaging made from these materials is often laminated with plastic or aluminium, making it non-recyclable and taking up more space in landfills.
To identify if a product is made of PET, look for the #1 symbol on the packaging. This symbol is typically found inside the triple arrow recycling symbol at the bottom of plastic packaging. Choosing products packaged in PET and ensuring proper recycling can contribute to a more sustainable future.

Polystyrene (PS) is challenging to recycle and not generally accepted
Plastic containers are typically categorized by a resin identification code, indicating the type of plastic and its recyclability. Polystyrene (PS), often found in foam food containers and referred to as "Styrofoam," is challenging to recycle and not generally accepted. It is identified as #6 in resin identification codes.
Polystyrene's recyclability challenge stems from its physical properties. It is a foam material that is relatively inflexible and maintains its shape when bent. This makes it difficult to process and separate from other recyclables during the recycling process. Additionally, polystyrene often contains food residue, oils, or grease, which can contaminate other recyclables and render them unrecyclable.
The challenges associated with polystyrene recycling have led to it being widely excluded from recycling programs. Many recycling facilities lack the specialized technology required to effectively recycle polystyrene. As a result, polystyrene is often directed to landfills, contributing to environmental pollution and waste accumulation.
However, it is important to note that some communities have implemented specialized polystyrene recycling programs. These programs often involve collecting and processing polystyrene separately from other recyclables. Individuals should consult their local waste management guidelines to understand if and how polystyrene can be recycled in their area.
While recycling polystyrene can be difficult, proper disposal and reduction in usage are crucial. When disposed of improperly, polystyrene can break down into smaller pieces, becoming microplastics that can contaminate soil and water. To minimize the environmental impact, individuals should prioritize reducing their use of polystyrene products and properly disposing of them through designated channels.
