Why is fire a distinct possibility in hot oil systems?

Fire is a distinct possibility in hot oil systems primarily because of the use of flammable products. In such systems, oils are often utilized for heating or transferring heat, and many of these oils can have low flash points, meaning they can ignite at relatively low temperatures when exposed to flames or sparks. As a result, if a hot oil system is not properly maintained or if there is a failure in the equipment, the risk of ignition increases significantly.

While overheating of fluids and installation errors are indeed risks associated with hot oil systems, they can lead to unsafe conditions that may contribute to the potential for fire, but the direct cause is often related to the flammability of the substances involved. Low efficiency ratings, while indicative of potential waste or mismanagement within the system, do not directly impact the fire risk as much as the properties of the fluid itself. Thus, understanding the inherent flammability of the products used is crucial in assessing fire risk in hot oil systems.
