Why should you not use oil-based spray with pilot lights on?

Using oil-based spray in the presence of pilot lights is particularly dangerous because oil-based products are flammable, and pilot lights generate heat. When these sprays are released into the air around an active pilot light, there is a significant risk of ignition, which can lead to fires or explosions.

The presence of an open flame or a hot surface means that any flammable aerosol or vapors can ignite immediately, creating a hazardous situation not only for the immediate area but also for the operator and surrounding environment. This underlines the importance of ensuring that any combustible materials are kept away from sources of ignition, especially in environments where the ventilation and safety protocols are critical.

The other considerations like effectiveness, equipment damage, or cleanup issues are certainly valid in different contexts but do not address the primary immediate safety concern associated with using flammable materials in conjunction with heat sources like pilot lights. Thus, the focus on flammability and heat generation correctly highlights the most critical safety issue at hand.
