A server room's relative humidity has dropped below 30%. Which of the following risks is MOST likely to increase as a result?
- ACorrosion of metal components
- BCondensation forming on equipment
- CMold growth inside server cases
- DElectrostatic discharge (ESD) damaging components
Show answer & explanationAnswer & explanation
Correct answer: D. Electrostatic discharge (ESD) damaging components
Low humidity dries out the air, increasing static electricity buildup and the risk of electrostatic discharge damaging sensitive electronic components. Corrosion, condensation, and mold are associated with excess humidity, not low humidity.
Why the other options are wrong
- A. Corrosion is more commonly linked to high humidity and moisture exposure.
- B. Condensation forms when humidity is high, not low.
- C. Mold requires moisture, which is reduced in low-humidity environments.
Humidity and ESD Risk
Low relative humidity in a server room increases the likelihood of electrostatic discharge, which can damage sensitive electronic components.
- Ideal data center humidity is typically 40-60%
- Low humidity = higher static electricity risk
- High humidity = condensation and corrosion risk
Memory trick: Dry air sparks; wet air rusts.
