Metalworking is the process of shaping metal using heavy machinery and machine tools. It is a complex process which requires proper safety precautions to prevent damage to the machinery and the health of those involved in the work. Coolants are often used in metalworking as a form of lubrication for the machinery and as a method for preventing heat buildup during operations. Several types of coolants are available depending on the metalworking process, including oils, water-soluble fluids, neat oils, and synthetic formulas. 

 

Metalworking coolants are an essential part of the machining process to

  • Extend tool life 
  • Improve surface finish 
  • Reduce the risk of fire and explosion

However, if not stored correctly, coolants become contaminated, leading to reduced performance and even health hazards for workers. This blog post covers the best practices for safely storing metalworking coolants to maintain their efficacy and keep your metalworking workshop running smoothly.


Metalworking coolant storage basics 


A few basic steps should be followed to store metalworking coolants.

 
1. Keep coolants in a dedicated storage area:  It is important to store coolants in a separate, well-ventilated area that is away from heat and potential ignition sources. This will help to reduce the risk of fire and explosion.

2. Store coolants in approved containers: Coolants should be stored in approved containers specifically designed for storing flammable liquids. These containers should be clearly labelled with the contents and appropriate hazard warnings.

3. Keep coolants out of direct sunlight: Exposure to sunlight can cause coolants to break down and become contaminated, so storing them in a cool, dark place is important. 

4. Use proper ventilation: Adequate ventilation is essential to prevent the build-up of flammable vapours.

5. Follow proper handling and disposal procedures: It is essential to follow the manufacturer's guidelines for handling and disposing of coolants to minimise the risk of spills and leaks. This may include using drip pans, spill kits, and other protective measures like a spill. 


Storage methods for oil & water-based coolants

 

 The storage method for coolants depends on the type of metalworking coolant you use. It is advised to follow the manufacturer’s recommendations to ensure the safest storage conditions for your valuable coolants.

 

However, based on their properties, here are a few tried and tested storage methods for oil and water-based coolants.

 

  • Water-based Metalworking Coolants

These coolants are typically stored in open containers. The chemical makeup of this type of metalworking coolant helps prevent bacteria growth and keeps it from evaporating quickly. These chemicals can be stored at room temperature without adversely affecting the quality or safety of the liquid inside the container. However, if you plan to store water-based liquid for an extended period, you should store it in a refrigerator or freezer to maintain a constant temperature.

 

  • Oil-based Metalworking Coolants

Oil-based coolants have a higher viscosity than water-based liquids and require special care when storing for long periods. These chemicals can be stored in closed containers like drums or plastic pails with tight-fitting lids that seal out oxygen completely. This will prevent any evaporation from occurring.

 

Final thoughts

 

When working with any coolant, it is essential to follow proper safety precautions to prevent exposure. Provide adequate personal protective equipment, such as gloves and safety goggles, to employees involved in metalworking operations to maintain the health of your employees.  

 

While ensuring to follow all recommended steps to increase the shelf life of your coolants, it is of equal importance to use high-quality metalworking fluids with superior formulations that maintain their efficiency in long-term storage.
