Thermal fluid systems have been operating safely for many decades across a range of industries. However, it is impossible to eliminate all risk in these systems because the ingredients for fire (fuel, air and an ignition source) are all present by design. 

While the established safety record of thermal fluid systems is a testament to proper system design and attentive maintenance practices, not all systems are designed and operated with best practices in mind. However, fire risk in thermal fluid systems can be minimized by understanding the causes of thermal fluid fires and mitigating those causes by observing vital installation practices for design, installation, operation and maintenance of the systems.
