TECHNICAL CURIOSITIES – NR20 INTEGRATION COURSE ENGLISH:

The Invisible Danger of Vapor Clouds
Flammable liquids often present a greater risk in their vapor phase than in liquid form. Vapors can spread horizontally along the ground, reach distant ignition sources, and ignite far from the original leak point. This behavior explains why accidents sometimes occur away from the visible source of the spill.

Flash Point Is Not Ignition Temperature
A common misconception is to confuse flash point with ignition temperature. Flash point is the minimum temperature at which a substance releases enough vapor to ignite momentarily in the presence of an ignition source, while ignition temperature is the point at which combustion occurs without external ignition. This distinction is critical for safe handling and storage.

Static Electricity Can Be Enough
In flammable environments, static electricity generated by simple movements such as walking, liquid transfer, or clothing friction can produce sufficient energy to ignite vapors. That is why bonding and grounding are essential preventive measures, even in operations that seem low risk.

Our pedagogical project follows the guidelines imposed by Regulatory Standard nº1.
