Why should you use a fire-resistant lubricant?
Shell Fire-Resistant Hydraulic Fluids are specially formulated to avoid the propagation of a flame and are difficult to ignite – reducing potential fire hazards and improving safety.
With more compact hydraulic systems that operate at growing power and under increasing pressure, fire risks are becoming more prominent in industrial settings – despite advances in safety.
Hydraulic systems that operate in severe conditions, extreme temperatures or near an ignition source face an increased risk of fire. So, protecting your people, your equipment and your business from this is essential.
Reasons to use fire-resistant hydraulic fluids
Reduce your impact on the environment
Mining or steel operations in environmentally sensitive settings need hydraulic fluids that not only deliver high levels of protection to equipment but also help you reduce the impact, of an accidental leak or spill, to the ecosystems around your facilities.
Our portfolio of specially formulated fire-resistant hydraulic fluids are difficult to ignite and designed not to propagate a flame from an ignition source, in comparison to mineral-based fluids.
It also features products that are classified as readily biodegradable with low eco-toxicity – engineered to reduce the impact of spills and leaks, helping you meet your environmental responsibilities.
Discover our fire-resistant hydraulic fluids
Our portfolio of fire-resistant hydraulic fluids is designed for effective fire-risk reduction, across a range of metal, industrial and mobile applications. Using fire-resistant lubricants is a cost-effective option compared with installing mechanical fire-suppression equipment.
We help customers to make the right selection for their business through a detailed dialogue about the products that could, and should, be selected for each application. This advice draws on Shell’s expertise with the products and the customer’s understanding of the end use.

Make a safe switch to fire-resistant hydraulic fluids
Switching from a mineral oil to a water-based or synthetic hydraulic fluid with fire-resistant properties is an effective way to improve the safety of your facilities. Using fire-resistant lubricants is a cost-effective option compared with installing mechanical fire-suppression equipment.
However, care must be taken to ensure the conversion is carried out correctly. It is important to review OEM requirements to confirm the compatibility of a lubricant with system components (including seals, hoses and filters). Even when using compatible lubricants, a small quantity of mineral oil can impair the fire resistance and stability of the new hydraulic fluid.
Similarly, when converting from one fire-resistant fluid category to another, the lubricants must not come into contact. Mixing incompatible lubricants can result in equipment failure. Even hydraulic fluids from the same category, but from different suppliers, should not be mixed unless you can clearly establish their compatibility. Be sure to consult with suppliers when looking to switch to an alternative hydraulic fluid.
