USP 800 / ASHRAE 170 Table 7-1
What it means on the job
USP 800 and ASHRAE 170 require hazardous drug (HD) compounding areas to be maintained at negative pressure relative to surrounding spaces with a minimum of 12 ACH and all air exhausted externally (no recirculation). Equal pressure means hazardous drug aerosols and vapors can escape into adjacent corridors, exposing staff and patients to carcinogenic and teratogenic compounds.

TIA-607-D 6.3
TIA-607 requires a telecommunications bonding busbar (TBB) in each telecom room to serve as the central bonding point for all telecom infrastructure. Without a TBB, there is no organized bonding system for racks, cable trays, and other telecom infrastructure.
TIA-942 / Uptime Institute Tier III+
This fails Tier III requirements. TIA-942 Tier III (Concurrently Maintainable) mandates multiple independent distribution paths serving the IT equipment, so that any single path can be shut down for planned maintenance without affecting the IT load. A single utility feed means the facility cannot perform maintenance on the incoming power infrastructure without relying entirely on generator backup, which does not satisfy the concurrent maintainability requirement. Tier III requires at least two active power distribution paths — typically dual utility feeds or a configuration where any single element from utility entrance to rack can be removed from service without impacting operations.
USP 797/800 / FGI Guidelines 2.5-2.3
USP 797/800 and FGI Guidelines require pharmaceutical storage areas to maintain temperatures between 68-77°F (20-25°C) for controlled room temperature drugs. At 78°F the room exceeds the limit, and without a temperature monitoring/alarm system, excursions can go undetected for hours or days, potentially rendering expensive medications ineffective or dangerous.
