Position the drum securely
Positioning the drum securely is an important first step in opening a plastic drum barrel. This process may vary depending on the type of drum and its contents, but there are some general guidelines to follow. Firstly, ensure that the drum is placed on a stable and flat surface to prevent it from rolling or moving during the opening process. A sturdy workbench or platform can provide a secure workspace. If your drum has been stored for an extended period, carefully inspect it for any signs of damage or leaks. This step is crucial, as leaks can cause the surface to become slippery and hazardous.
When positioning the drum, ensure the bung, which is the opening at the top of the drum, is facing upwards. The bung is where you will be working to open the drum, so having it easily accessible is essential. If your drum has a lid or cover, check that it is securely closed before proceeding. Additionally, confirm that the drum is locked securely in place and cannot be accidentally knocked over. This can be achieved by using a drum with a flanged base, which provides extra stability and secure handling.
For larger drums, such as 55-gallon drums, the weight of the contents can make the drum challenging to move. In such cases, it is advisable to have an assistant help position and secure the drum. Once the drum is securely positioned, you can proceed with the opening process, following the specific instructions for your drum type. Remember to always wear protective gear, such as gloves and goggles, to safeguard against any potential spills or accidents during the opening process.
To summarise, positioning the drum securely involves choosing a stable workspace, inspecting the drum for damage or leaks, orienting the bung upwards, ensuring the lid is secure, and stabilising the drum to prevent accidental movement. By following these steps, you can create a safe and controlled environment for opening your plastic drum barrel.

Locate the bung holes
Locating the bung hole is an important step in opening a plastic drum barrel. A bung hole is the opening on the top of the drum, and it is usually closed off with a male threaded bung. Different types of drums have different types of bung holes. For example, on a PE drum, the bunghole is formed during the moulding process, whereas on a steel drum, the bunghole is added later as a press-fit octagonal flange in the drum top or lid. Drums of this kind typically have one or two female threaded bungholes.
To open a plastic drum barrel, you will need to locate the bung hole and remove the bung. This can be done using a drum wrench, which is designed to open various bung caps on plastic and steel drums. The drum wrench is made of high-density polyethylene (HDPE) plastic, which makes it lightweight, durable, and corrosion-resistant. It is also non-sparking, making it safe for use in environments with flammable substances.
If you do not have access to a drum wrench, there are alternative tools and methods you can use. One option is to use a pair of pliers to grip the bolt on the bung cap and turn it counterclockwise to loosen it gradually. Another method is to use a hammer and a screwdriver to gently ease the bung cap off. You can also use a pipe wrench as an alternative to a drum wrench to grip the edges of the bung cap and turn it counterclockwise.
It is important to take safety precautions when working with plastic drum barrels. Always wear appropriate personal protective equipment, such as gloves and goggles, to protect yourself from potential spills or hazards. Additionally, ensure that you follow proper procedures for handling any hazardous materials that may be inside the drum.

Use a drum wrench to loosen the ring clamp
To open a plastic drum barrel, you'll need to loosen the ring clamp with a drum wrench. This process can be tricky, so it's important to follow these steps carefully:
First, ensure you have the correct size of drum wrench for your barrel. Drum wrenches are designed to fit snugly around the ring clamp, so choosing the right size is essential. You may need to adjust the wrench to fit your particular barrel.
Once you have the correct wrench, position it securely around the ring clamp. The wrench should have a firm grip on the clamp to avoid slippage during the loosening process. Apply steady pressure to the wrench, maintaining firm contact with the clamp. You may need to adjust the amount of pressure you apply, being careful not to use excessive force that could damage the clamp or barrel.
If the ring clamp is particularly tight, you can try using a cheater bar to increase your leverage. A cheater bar is simply a length of pipe that fits over the handle of your wrench, giving you more torque to loosen the clamp. Again, be cautious not to use too much force, as this could damage the barrel.
In some cases, the ring clamp may be resistant to your efforts. If this happens, there are a few additional techniques you can try. One method is to apply a suitable oil to the clamp and allow it to sit for 15 to 30 minutes before attempting to loosen it again with the wrench. Another approach is to use a small hammer or mallet to gently tap around the edges of the clamp. The vibrations from the tapping can help dislodge rust or corrosion, making the clamp easier to loosen.
By following these steps and using a drum wrench correctly, you should be able to successfully loosen the ring clamp on your plastic drum barrel.

Use pliers to grip the bolt and turn counter-clockwise
To open a plastic drum barrel, you will need to remove the caps from the bung holes, which are the openings where you can insert a tool or pump to access the contents of the drum. One way to do this is by using a pair of pliers.
If you have a pair of pliers handy, you can grip the bolt on the bung cap and turn it counter-clockwise to gradually loosen the cap. Open the pliers by pulling the handles away from each other, and locate the plier mouth adjustment bolt at the end of the fixed handle. Screw counter-clockwise to accommodate the large size of the bolt. Place the jaws on the bolt to size for adjustment. If you squeeze the handles and the jaws don't lock, you'll need to make the mouth wider.
To loosen the bolt, use the pliers as you would a wrench, turning counter-clockwise. Push the locking plate flush to the handle, and the pliers will pop open. This process is the same as removing a broken bolt with vise grips, where the jaws of the vise grip tighten around the bolt head, and then the handles are used as a type of lever to loosen the bolt.
If you are having trouble getting a grip on the bolt, you can use a method where you first apply penetrating oil to the surface of the bolt. This will make it easier to loosen. You can also use a propane torch to heat the bolt for 30 seconds, which will cause the metal to expand and make it easier to unscrew.
