What Environmental Monitoring Audits Cover
Environmental monitoring is the system through which a company confirms that its cleanrooms remain in control. It covers viable and non viable particles, temperature, humidity, and pressure differentials.
A GMP audit for environmental monitoring assesses whether monitoring is defined, whether sampling is performed, whether results are trended, and whether action is taken when needed. The scope includes sampling plans, methods, trending, and action.
