How can low humidity have a negative impact on the data center environment?

Question

Options

• AIt can create a static electricity discharge.
• BIt can create the potential for life threatening electric shock.
• CIt can decrease the sensible heat ratio of the air conditioner.
• DIt can accelerate the deterioration of internal system components.

• A
  77% (27)
• B
  6% (2)
• C
  14% (5)
• D
  3% (1)

Explanation

Low humidity in a data center allows static electricity to build up on surfaces and people, and without sufficient moisture in the air to dissipate that charge, even a small discharge can damage or destroy sensitive electronic components. Option B is wrong because static discharge, while harmful to equipment, operates at voltages too low to endanger human life -- life-threatening electric shock comes from power systems, not static buildup. Option C is wrong because humidity affects latent heat load, not the sensible heat ratio in a way that would be considered a negative environmental impact in this context. Option D is wrong because it is high humidity, not low humidity, that accelerates corrosion and physical deterioration of components through condensation and oxidation.

Memory tip: Think "dry air, sparky affair" -- low humidity means no moisture to ground static charges, making components vulnerable to electrostatic discharge (ESD).
