What indicates that a desiccant lay-up is within requirements?

• A. Humidity indicator cards
• B. Moisture meters
• C. Temperature gauges
• D. Pressure indicators

Answer: (A)

Humidity indicator cards are specifically designed to indicate the moisture content in the air surrounding desiccants used during equipment lay-ups. These cards change color based on the relative humidity levels, providing a visual assessment of whether the environment is within the required range for the proper functioning of desiccants. When the humidity level is low, the card typically will show a color indicating dryness, which means that the desiccants are performing effectively by removing moisture from the air. Conversely, if the card indicates high humidity, it signals that the desiccants may be saturated or ineffective, necessitating replacement. Thus, humidity indicator cards serve as a direct and convenient method for monitoring the lay-up environment and ensuring that the moisture levels remain within acceptable limits for the protection of machinery and equipment. Moisture meters, while also able to measure humidity, are not typically used for desiccant lay-ups in layman's terms as humidity indicator cards are; temperature gauges and pressure indicators do not provide a relevant measure of moisture levels in this context.
