What Are Bic Lighters Made of

The reservoir of BIC lighters is made from Delrin. Compared to regular lighters, Delrin allows for more room for gas with its thin structure. But albeit the thinner material, this is a high-grade resin that can withstand impact. So in case it falls, it will not shatter easily as other lighters will.

What Kind of Fluid Do Bic Lighters Use

What is inside a bic lighter? 

Bic lighter makes use of butane. Butane is a liquified petroleum gas and is pressurized. It’s a colorless and odorless gas. Since it’s highly flammable, there were questions raised if butane is safe to use.

It’s a different type of fuel used by lighters such as Zippo. Zippo lighters use a heavy naphtha fuel, which is almost similar to kerosene or the fuel used for jet engines. Since it’s not pressurized like butane, it’s less flammable.

Albeit butane being more flammable, it’s still considered one of the safest fuels to store for use indoors and outdoors. Thus, to be able to use and store butane safely, you have to follow several safety guidelines. 

How to Safely Use and Store Butane

Alternating, all types of gas fuel can pose a health hazard if not used and stored properly. That’s why extra caution should be practiced when refilling your lighters, whatever brand it is, and whatever type of fuel they use. 

Below are simple steps that you can practice to ensure safety when using butane at home and outdoors.

  1. Avoid inhaling butane when you are refilling your lighters.  
  2. Store butane canisters away from any source of flame or heat. The pressurized can easily explode when subjected to heat or placed near an open flame.
  3. Never light a cigarette when you’re using butane.
  4. Use only advisable containers for storage.
  5. Store butane away from food or any drink. And keep it in a well-ventilated area.
  6. Storage containers should be sealed and properly labeled. 
  7. When you’re refiling a container, ground and bound the container to prevent an explosion.
  8. Either wash or throw away any clothing material that has been in contact with butane. Take note that sometimes it can start a fire in the washing machine.
  9. Keep out of children’s reach.

How Does a Bic Lighter Work

Before refilling a bic lighter with butane, it’s important to get to know the mechanism of the lighter first. Most likely you already know how it works. So you just need to familiarize yourself with the parts and the mechanism.

Spark wheel

The spark wheel is the serrated metal wheel. You might be familiar with this already as this is the one that you flick to ignite the lighter.

Take note that when you roll down the wheel, it will strike a piece of lint. This creates that spark that will ignite the gas from the fuel. Thus creating a flame.

Ignition button

The Ignition button will release the gas from the valve. When you flick the spark wheel with your thumb, the ignition button is pressed and you have to hold the ignition button until the flame comes out. The ignition button is also referred to as the fork.


The flint supplies the material for the ignition. And it is controlled by the flint spring.

Fork spring

These springs control the opening and closing of the valve that contains the gas.


The valve regulates the flow of the fuel.

How to Refill a Bic Lighter at Home

Lighters such as BIC lighters are essentially disposable items. Once it runs out of fuel, you have to toss it into the trash bin. But many may not know yet that it is indeed refillable. And you can refill it in your own homes. 

And here are simple steps on how to.

  1. Gather the materials that we will be needing. Secure the items below.
  • A flat screwdriver or a butter knife
  • Paper clip, wire, or a tack
  • The empty BIC lighter
  • Lighter fluid
  • Extra flint

2. Ensure first that your BIC lighter is empty. Never refill your layer if it still has fuel. And you can check it by flicking the spark wheel several times. If it does not light anymore, it’s out of fuel.

3. Another way of checking if the lighter is empty is by holding a source of light over the lighter. 

4. Pry open the metal part from the sides off. You can use the butter knit or a flat screwdriver. The hood shield should be able to come right off.

5. Then look for the guard. Point the lighter away from you so it will not hit your face. You may also use the butter knife or flat screwdriver to pry open the guard. 

6. Now it’s time to remove the spark wheel. Extra caution should be practiced because you don’t want the parts to be damaged. It’s easy to find the spark wheel. It’s the wheel that you flick to generate a flame. 

7. Remove the flint and the spring.

8. Look for the flame adjuster and turn it off counter-clockwise 10 times.

9. Press a wire of tack or paper clip. under the fork. We need to keep this part open as this is where the gas is released from the valve.

10. Get your butane fuel. And attach the nozzle front of the lighter fluid to the opened fork. Press it to refill the Bic lighter.

11. One refueled, close the open valve by pulling the wire off the fork.

12. Return the flame adjuster and turn it clockwise ten times. 

13. Return the spring in the flint back on. Though you may need to replace the flint since it’s bound to wear and tear. The flint delivers the spark to the lighter. So by the time the lighter runs out of fuel, the flint would have needed replacement too.

14. Return the spark wheel and ensure it is assembled properly. You may also opt to put the child safety guard on.

15. Attach the metal hood back.

16. Check to see if it works by flicking the spark wheel.

What to Do if You Have Exposed to Butane Gas

Because sometimes no matter how careful you are, accidents are bound to happen. And in case it does, here is what you should do.

  1. In case butane got into contact with your eyes, flush them with running water for 25 minutes. Make sure the whole surface of your eye is washed
  2. If your skin gets in contact with the lighter fluid, wash it with warm water asap.
  3. If you have inhaled the gas, go to a well-ventilated area. But if there is already irregular breathing or worse it stops, call medical assistance asap. You may get artificial respiration until help arrives.

Though serious, these situations are very unlikely to happen if you use butane with caution. 

What to Do With an Empty Bic Lighter

 If you cannot refuel your BIC lighters, you have to dispose of them properly.

Make sure that your BIC lighters are empty before disposing of them. Never throw lighters with liquid fuel in the trash, this is a fire hazard

If there is still a bit of fuel left in your BIC lighter, dispose of them and take them to a hazardous waste collection site instead.  

Can they be recycled? Yes, they can be recycled. However, lighters have metal and plastic parts that can be difficult to disassemble for recycling. 

How Long Does a Bic Lighter Last

Full-sized BIC lighters can burn for an hour if used continuously. Though it’s not really standard practice to burn a lighter continuously. And if you do, the top part will actually start to deform in just twenty minutes.

Smaller BIC lighters, on the other hand, can light continuously for about twenty minutes.
