An infrared gas analyzer (Foxboro Miran Sapphire) will be used to make on-site determinations for acetic acid. Real time readings will be taken at various source locations, at short intervals of time to provide an integrated personal exposure analysis.
HEALTH CHOICE will also determine air exchange rates by measuring ventilation supply air flow in locations where the monitoring is performed. A Shortridge flowhood will be used to obtain the air flow measurements.
Note: Air exchange testing may be skipped in program if PEL levels are found to be well below the action level.
