At what temperature is a surface considered hot for fuel oils?

A surface is considered hot for fuel oils at 400°F (205°C) because this temperature is critical in the context of handling and storing fuel oils. Operating at or above this temperature can lead to increased risks, such as vaporization of combustible components, potential fire hazards, and damage to equipment if materials are not properly rated for high temperatures.

At temperatures around 400°F, the properties of fuel oils can change, affecting their viscosity and volatility. It is crucial for personnel to adhere to safety standards and operational guidelines to ensure safe handling practices at high temperatures. Understanding the implications of these temperatures helps in maintaining safe operations and preventing accidents in environments where fuel oils are present.
