DPV rooms are required to be what two characteristics?

DPV rooms are essential for the effective functioning and maintenance of fire protection systems, particularly with dry chemical agents or during the performance of various inspections and tests. These rooms must be adequately lighted to ensure that personnel can safely and effectively perform their duties without risk of accidents or errors due to poor visibility.

Heating is critical in a DPV room as well, particularly to prevent moisture build-up and ensure that any equipment or systems housed within the room operate within their optimal temperature ranges. Low temperatures can adversely affect both electrical equipment and fire suppression agents, leading to reduced efficacy or equipment failures.

While ventilated rooms are also important in many contexts, the primary requirements specifically for DPV rooms focus on adequate lighting and heating, ensuring safety and functional integrity. Thus, the characteristics of being lighted and heated are essential for maintaining an operational environment conducive to fire prevention and safety standards.
