What is a potential risk associated with low humidity environments during refueling?

In low humidity environments, the moisture content in the air is significantly reduced, which can lead to an increase in static electricity build-up. This is particularly relevant during refueling operations, where the flow of fuel through hoses and pipes can generate static charges. Since fuel is highly flammable, any static discharge poses a serious fire risk.

The generation of static electricity can result in sparks that could ignite fuel vapors, leading to potential fires or explosions. Therefore, recognizing and mitigating the risks associated with static charge generation in low humidity conditions is critical for ensuring safety during refueling operations.

This understanding highlights the importance of implementing safety protocols, such as grounding and bonding, to prevent static discharge from becoming a hazard during the refueling process.
