What Is a Chemical Bund and Why Does Your Facility Need One?

Q: What size of chemical bund do you need?

The right bund size depends on how much hazardous liquid you store and the size of your largest container . As a general rule, a bund should be able to hold more than the contents of your largest drum or tank , giving it enough capacity to contain a major spill and any additional liquid used during an emergency. If your facility stores several containers together, the bund should be designed to safely contain a significant portion of the total stored volume—not just one container. It is also good practice to store incompatible chemicals in separate bunds to prevent dangerous chemical reactions if two substances leak at the same time. From our experience, many businesses focus only on the number of containers they have. In reality, you should also think about future storage needs. Choosing a bund with a little extra capacity today can save you the cost of replacing it as your operations grow.

If your facility stores or handles hazardous liquids, such as corrosive chemicals, oils, fuels, or other dangerous substances, you may need a chemical bund. If there is any risk that a spill or leak could harm people, damage property, or pollute the environment, a bund is one of the simplest ways to reduce that risk.

So, what exactly is a chemical bund system? Technically, a chemical bund is a tray or containment barrier made of stone, concrete, or other material. It is a secondary containment system.

So if you ask, “Should you really need to install a chemical bund in your industrial facility?”

The shortest answer will be yes.

To put it another way, a chemical bund prevents the risk of leaks and hazardous effects on the environment and property from harmful liquid releases. It also supports workplace safety and compliance regulations.

In this blog, we will understand what a chemical bund is and the reasons for installing a chemical bund in your facility.

Key Takeaways

A chemical bund is a simple but essential safety system that helps contain hazardous spills before they spread.
It protects your employees, the environment, and your facility while helping you meet safety and environmental regulations.
Choosing the right bund depends on the type of chemicals you store, the storage volume, and how your facility operates.
Investing in the correct chemical bund today can prevent costly clean-ups, reduce risks, and keep your business running safely and efficiently.

If Your Facility…	Why a Chemical Bund Is Important
Stores hazardous or corrosive chemicals	Helps contain leaks and prevents harmful chemicals from spreading.
Uses drums, IBCs, or chemical storage tanks	Provides secondary containment if a container fails or is damaged.
Is close to drains, soil, or watercourses	Reduces the risk of environmental pollution from chemical spills.
Has employees working around stored chemicals	Lowers the risk of slips, chemical exposure, and workplace injuries.
Wants to comply with safety and environmental regulations	Supports legal compliance and demonstrates good safety practices.
Handles expensive chemicals	Increases the chance of recovering spilled liquids, reducing product loss.
Wants to reduce clean-up costs and downtime	Contains spills at the source, making clean-up quicker and less expensive.
Plans to expand chemical storage in the future	Choosing the right bund now can support future storage needs and avoid costly replacements.

What is a Chemical Bund?

A chemical bund system is like a tray or containment area. It bunds or encloses the surroundings of the IBC, drums, or tanks.

In many cases, a chemical storage bund is also used as a tray, which is placed under these drums. Chemical storage areas are regularly inspected. However, even if any such hazard happens, these storage bunds will hold the liquid.

It will stop the spill from flowing into the environment, such as soils or water bodies. It also prevents the chance of any personnel injury from spreading in the walkways or contamination of harmful liquid.

What Are the Reasons to Have a Chemical Bund In Your Facility?

Here are some of the main reasons why your industrial and commercial facilities should install chemical bunds:

Prevent the Chance of Workplace Injury

When a chemical leaks, it can quickly spread across the floor. So, it can cause slip injuries or other health hazards from direct exposure or from inhaling its vapours.  When you bund the chemical storage, you are actually making your facility safer for staff and easier to manage.

Reduce the Risk of Environmental Pollution

When the chemical storage is not under a bund, it flows directly to the site after a leak.  It goes into the drainage and is released into the water bodies. If that way is closed, it can vaporize in the air. Then it pollutes the nearby water bodies, soils, and leaves a long-term effect on public health.

Save the Cost of Clean Up

At any time, when a spillage happens, cleaning up becomes the greatest liability. Often, you will need specialist equipment and waste disposal… and sometimes repairs. Then a sudden shutdown happens to the work. Think of the cost; isn’t it huge?

When you choose a chemical bund for your facility, you contain the spill at its source. It reduces the area affected. As a result, you can end the clean-up process more quickly and more affordably.

Improve the Chance of Spilled Liquid Recovery

Chemicals are the backbone of industries. Many of the chemicals are very costly or even rare. You may import them from outside. And it takes months. If they leak onto the ground, they are usually lost. When the liquid is contained inside a bund, there is often a better chance of recovering it safely.

Compliance with Safety Rules

As we have said, if you are not using a chemical bund in your facility, you are actually putting compliance at risk. You can get legal notice due to personnel injury or environmental pollution. All these happen due to a lack of safety maintenance.

How Do You Decide You Need a Chemical Bund?

Here are a few questions you should ask yourself to understand the requirements:

Do you store harmful or inflammable chemicals at your site?
What is the level of risk at your site?
What is the type of your facility?
What is the condition of the drainage system of your site?
For how long do you plan to store the liquids?
How much chemical do you want to store?
How do you dispense the chemicals?

Final Thoughts

A chemical bund may seem like a simple addition to your facility, but it plays an important role in protecting your people, your property, and the environment. Choosing the right chemical bund today can help you avoid expensive clean-ups, and reduce environmental risks. It helps to keep your operations running safely and smoothly for years to come.

How do I know which chemical bund is right for my facility?

The right choice depends on the type of chemicals you store, how they are handled, and the way your facility operates.

For example, plastic bunds are commonly used for storing corrosive chemicals because they offer excellent chemical resistance. Steel bunds are often preferred where containers need to be moved by forklift or where greater structural strength is required. In some cases, facilities use steel bunds with protective liners to combine strength with chemical resistance.

One of the best pieces of advice we can give a facility manager is not to select a bund solely on cost. A bund designed to contain your chemicals while using your method of handling and storage will provide effective protection, have a longer life cycle, and assist in avoiding recurrence of expensive incidents in the future.
