Absorbent Pad

Spill Control Centre explains the difference between different absorbent pads for different kinds of spill allowing you to select the right one for your requirements.

Like golf clubs and kitchen knives, absorbent pads are designed for different tasks, which is why selecting the right one is important. They all have the same general function of cleaning up spills (or catching them as they happen), but it’s what needs to be mopped up that dictates which is the right ‘tool for the job’.

Absorbent pads come in three basic types – to deal with (1) oil, (2) chemicals, and (3) water or general tasks. There’s a colour coding system to explain which one does what job:

• Oil absorbent pads are white
• Chemical absorbent pads are yellow
• General purpose and water absorbent pads are black or grey; these are also known as ‘maintenance’ absorbent pads

White oil absorbent pads

These are made using clever polymers or cotton fibres that are hydrophobic. This means they actually repel water, making them ideal for lifting oil from the surface of ponds and streams. The benefit with this type of pad is that its entire capacity for absorption is therefore used on the spill, which needs to be cleaned up, rather than the pre-existing water, which doesn’t. The other benefit of using a white oil absorbent pad is that the absorbed oil changes the colour of the pad, so it’s easy to see when it’s ‘full’ and needs replacing. (The accompanying picture shows these pads in use during an oil spill in Thailand).

Yellow chemical absorbent pads

These are the ones to use to absorb all industrial liquids, including aggressive chemicals, like those that are corrosive or caustic, as well as coolants and any solvent-based spill. It’s important to remember that aggressive chemicals soaked up by these pads remain aggressive, as a result of which two things are worth mentioning.

Firstly, as much care should be taken with handling and disposing of the pads as would have been the case with the original chemical itself. Secondly, because of their robust polypropylene construction they won’t break up in or after use, which would make the clean-up unnecessarily awkward and potentially hazardous.

 

Keeping Your Workplace Clean and Safe

Introduction

In industrial settings, spills and leaks are a common occurrence. Whether it's oil, chemicals, or other hazardous substances, these spills pose a significant risk to the environment, as well as the health and safety of employees. That's where oil absorbent pads come in. With their ability to quickly and effectively soak up oil and other fluids, these pads are an essential tool in maintaining a clean and safe workplace.

The Function of Oil Absorbent Pads

Oil absorbent pads are specifically designed to absorb and contain oil and other hydrocarbon-based fluids. They are made from a combination of materials, such as polypropylene or recycled cotton, that have excellent absorbent properties. These pads are available in a variety of sizes and weights to accommodate different spill sizes and types.

How Do Oil Absorbent Pads Work?

Oil absorbent pads work on the principle of adsorption. This process involves the liquid molecules adhering to the surface of the pad's fibers. When a spill occurs, simply place the pad on top of the spill, and it will begin to soak up the oil. The pad's absorbent fibers quickly pull the oil into its core, trapping it and preventing it from spreading or leaking. The result is a cleaner and safer work environment.

The Benefits of Using Oil Absorbent Pads

1. Easy and Convenient

One of the main benefits of using oil absorbent pads is their ease of use. They are lightweight and portable, making them easy to transport and store. When a spill occurs, simply grab a pad and place it over the spill. No additional tools or equipment are required.
