About this file
Attachment C is a comprehensive document detailing the required tests and inspections for fire suppression and sprinkler systems at the National Institute of Environmental Health Sciences (NIEHS). The document outlines specific inspection and testing requirements for two primary systems: Pre-Action and Dry Pipe Sprinkler Systems (following NFPA 25 standards) and Sapphire Clean Agent Suppression Systems (following NFPA 2001 standards), with inspection frequencies ranging from quarterly to five-year intervals.
The inspection schedule covers multiple locations, including Building 101 Cafeteria and Building 104 CCR, and includes detailed testing protocols such as examining supervisory devices, testing waterflow switches, checking system batteries, conducting full flow trip tests, replacing sprinkler heads, and performing visual inspections of agent cylinders. Each system has a prescribed set of tests at different intervals, with specific actions noted for quarterly, semi-annual, annual, 3-year, and 5-year inspection cycles, all to be accomplished during a designated option year of the contract.
