What You'll Learn

Tightly secure the filler cap
Tightly securing the filler cap is a crucial step after filling your fuel tanks. This simple action helps prevent the escape of fuel vapors, reducing both safety and environmental risks. Here are some reasons why tightly securing the filler cap is essential:
Firstly, a tightly secured filler cap acts as a safety measure to prevent fuel spills. Fuel spills can occur if the cap is loose or not properly secured. Spills can cause fuel to escape onto the road or into the water, leading to hazardous situations. On the road, a fuel spill can create a dangerous driving surface, posing a risk to yourself and other drivers. For boats, a fuel spill directly impacts the marine environment, harming marine life and causing water pollution.
Secondly, a tight filler cap helps contain fuel vapors. Fuel, especially gasoline, gives off vapors that can accumulate and create an explosive or flammable environment. By securing the filler cap, you minimize the escape of these vapors, reducing the risk of fire or explosion. This is particularly important for boats, as fuel vapors can build up in enclosed spaces, posing a serious safety hazard.
Additionally, a properly secured filler cap helps maintain the integrity of your fuel system. It ensures that debris, dust, or moisture do not enter the fuel tank, which could contaminate the fuel and cause engine issues. A loose cap leaves your fuel tank vulnerable to these contaminants, potentially leading to costly repairs and engine performance problems.
Furthermore, in some vehicles, a properly secured filler cap is necessary for accurate fuel gauge readings. A loose cap can cause the fuel gauge to provide inaccurate information, leading to unexpected fuel shortages or overfilling. This can be especially problematic for boats, as running out of fuel while on the water can be dangerous and inconvenient.
Lastly, a tightly secured filler cap helps reduce fuel evaporation and minimize fuel loss. Gasoline is highly volatile and can evaporate quickly, especially in hot weather. A secure filler cap slows down this evaporation process, ensuring that you get the most out of your fuel and reducing the environmental impact of fuel evaporation.

Wipe up any spills or leaks
It is important to wipe up any spills or leaks immediately. Spills can occur due to an uncovered vent, so it is a good idea to hold an absorbent pad over the opening while fuelling. If a spill occurs, the first step is to stop the source of the leak. Then, use an oil absorbent pad to clean up any fuel that has spilled onto hard surfaces. If the spill has entered the water, it is important to contact your marina and notify them. Depending on the size of the spill, you may also need to call the U.S. Coast Guard at 1-800-424-8802. If the spill is substantial, it is recommended that you also call your insurance company.
It is illegal to leave an oil or fuel spill unreported if it leaves a sheen on the water. You are responsible for any environmental damage caused by your spill. It is also illegal to use detergent or other chemicals to disperse the spill, as this can cause more harm to the environment and marine life. Preventing spills is beneficial for both you and the boating environment.
When refuelling, it is important to never overfill your tank. This can increase the risk of explosion or fire if fuel spills into the engine or passenger compartment. Spilling fuel into the water will also harm the marine environment. To avoid spills, do not fill your boat fuel tank above 90% full. This leaves room for the gas to expand and avoids the potential for overflow. Ensure that all air vents and valves to the gas tank are open. After fuelling, tightly replace the gas cap to prevent the escape of fuel vapours.
Before starting the engine, check for the smell of fuel vapours or odours. If you detect excessive fuel odours, do not restart your engine. Instead, increase air circulation and wait until the fumes have fully dissipated. If you have an inboard gasoline engine, turn on the blower for at least four minutes before starting your boat to remove any lingering fumes.

Ventilate the area
Once you have finished fuelling your boat, it is important to ventilate the area. This is because fuel vapours are highly flammable and can cause an explosion if ignited. Therefore, you should always ensure that the area is well-ventilated before starting your engine.
To ventilate the area, you should open any ports, hatches, and doors to allow fresh air to circulate and dispel any fumes that may have built up during fuelling. It is also recommended to use a blower to increase air circulation and remove any lingering fumes. This is especially important if you have an inboard gasoline engine, in which case you should run the blower for at least four minutes before starting your boat.
If you have spilled any fuel, it is important to clean it up immediately to prevent it from igniting or leaking into the water. Use oil absorbent pads or booms to soak up any spills and prevent them from spreading. If the spill is significant or has entered the water, you must report it to the relevant authorities, such as the U.S. Coast Guard or your local marina.
Additionally, you should always check for fuel vapours or odours before starting your engine. Do not restart your engine if you detect excessive fuel odours. This is an important step to ensure that the area is adequately ventilated and safe to operate your boat.

Check for fumes before starting the engine
Fumes from fuel can be extremely dangerous and even cause explosions, so it is important to check for fumes before starting the engine. If you are using a boat with an inboard gasoline engine, turn on the blower for at least four minutes before starting the engine to remove any fumes that could be lingering in the bilge. Make sure all closed compartments are reopened after fuelling to ensure air circulation and eliminate gasoline fumes before turning on the engine.
Before starting the engine, take a good sniff to see if any fumes have escaped. If you smell fumes, increase air circulation to the area and wait until the fumes have fully dissipated before turning on the engine. If you have an inboard gasoline engine, you need to turn on the blower for four full minutes before starting your boat. This very important step is to remove any fumes that could be lingering in the bilge.
If you are using portable tanks, store them in a well-ventilated area away from the engine and any electrical equipment. It is also important to know that refuelling during the day is much safer than at night. Night fuelling will require the use of additional lighting, which should not be used near gasoline. If you must refuel in the dark, use electric lights only as they pose the least risk.
It is also important to know the type of fuel you are using. Compressed Natural Gas (CNG) fumes can combine with oxygen to form a powerful explosive. LPG or Liquefied Petroleum Gas is made up of propane and butane, which have some advantages over CNG. Kerosene is also used on boats for heating, lighting, and cooking. It must be totally clean and white to work properly. Alcohol is used for stoves and is relatively safe as it can be put out with water, but it may take a while to boil water. Electricity is probably the safest "fuel" as there are no explosive fumes or pressurized fuel systems that can develop dangerous leaks.

Store portable fuel tanks in a well-ventilated area
When storing portable fuel tanks, safety should always be the top priority. Improper storage increases the risk of leaks, explosions, or fires. All it takes is a lack of proper ventilation, excessive heat, or a damaged tank to create a dangerous situation.
Firstly, it is important to note that fuel vapors are heavier than air and will flow downhill. Therefore, the ideal location for storing portable fuel tanks is outdoors in a well-ventilated area away from other buildings, ignition sources, and electrical equipment. LP tanks should be left in the open and not enclosed in any way. Liquid fuel tanks can be stored in a well-ventilated building or open lean-to to prevent solar heating from evaporating the fuel. If the storage location is permanent, consider using a buried tank to protect the fuel from potential dangers such as gunfire, brushfires, and environmental damage.
Secondly, ensure that the tanks are stored upright at all times. This position keeps the pressure release valve in a safe spot, reducing the risk of leaks or vapour buildup. Keep the tanks dry and rust-free by storing them off the ground or on a dry concrete surface. Check your storage space for any signs of moisture as humid or damp areas can cause rust to form on the cylinder, weakening its integrity over time.
Lastly, avoid exposure to high heat or direct sunlight. Consistently high temperatures can cause the pressure inside the tank to increase, potentially releasing built-up gas through the pressure relief valve. Place the tanks in a shaded area away from direct sunlight to prevent overheating while keeping them cool and safe. Do not cover the tanks with materials like tarps or plastic that can trap heat. Additionally, keep the tanks away from flammable materials such as gasoline, oil, or lighter fluid.
