Maintain proper humidity levels. High humidity levels cause galvanic
actions to occur between some dissimilar metals. This eventually causes a
high resistance between connections, leading to equipment failure.
Low humidity contributes to undesirably high levels of electrostatic
charges. This increases the electrostatic discharge (ESD) voltage potential.
ESD can cause component damage during servicing operations.
Low humidity levels are often the result of the facility heating system and
occur during the cold season. Most heating systems provide air with a low
humidity level, unless the system has a built-in humidifier.
