Factory Mutual Certified & Labeled as "Fire Resistant Fluid"
"Fire-resistant" as defined by the Factory Mutual Research Corp:
- Sprayed fluid that contacts an ignition source will not propagate flame
- That if the source of ignition is removed from a fluid spray, any flames will self extinguish

Hydro Safe® ISO VG-68 FR is a vegetable based hydraulic fluid formulated to meet the demand for biodegradable hydraulic oils. It is designed to minimize environmental impact and have low environmental persistence. Hydro Safe® ISO VG-68 FR offers excellent performance in a wide array of hydraulic components, and can be used as a superior replacement for conventional petroleum oil. It exhibits excellent thermal and oxidative properties when compared to other vegetable-derived products. Hydro Safe® is formulated from canola (rapeseed) oil, and containing biodegradable, non-toxic chemical additives. Its high viscosity index (VI) allows outdoor operations in winter and summer without the need for fluid changes or equipment modifications. Hydro Safe® ISO VG-68 FR is factory mutual approved as a less-hazardous fluid.
Viscosity Index ASTM D-567, ASA Z11.45 is an empirical number indicating the rate of change in viscosity of an oil within a given temperature range. A low viscosity index signifies a relatively large change in viscosity with the temperature, while a high viscosity index shows a relatively small change in viscosity with temperature. Viscosity Index cannot be used to measure any other quality of an oil.
The fluid is totally biodegradable, and exceeds the government criteria of being "readily biodegradable." Readily biodegradable is defined as an attribute of products that have a natural ability to biodegrade quickly and completely. Once the fluid is leaked into the ground, it has the ability of substance to be digested or consumed by naturally occurring microorganisms present in water, air, and soil systems. Complete biodegradability is the conversion of a substance to carbon dioxide and water.
