Air Quality Information System

WHY?

	SAFETY FIRST AQIS is a new approach to providing air quality information in occupied spaces.
	RISK MITIGATION AQIS Alert protocols provide an intervention strategy ahead of a full alarm condition that could allow a response team to resolve a problem before an alarm condition is reached.
	INFORMATION AQIS develops and distributes Air Quality Information alerts when a monitored contaminant is detected in occupied space.
	REAL TIME AQIS provides real time updates about airborne contamination levels.

WHAT DOES IT DO?

AQIS can monitor levels of many airborne contaminants that are considered risky or dangerous in occupied spaces. It will:

Pinpoint the location where a sensor has detected a sustained and measureable contamination level.
Qualifies the identity of a contaminant based on the substance the sensor is designed to measure.
Provides real time measurement of the contaminants levels as well as increases and decreases in concentration.
Uses wireless technology to deliver critical event information to any communications device approved by user.

01	EARLY WARNING AQIS provides situational awareness alerts prior to protocol alarms being triggered.
02	ALERT BEFORE ALARM AQIS alerts response team prior to initiating protocol alarms to prevent unsettled responses from persons in the occupied space.
03	FORECASTING Uses real time algorithms to forecast a trending increase in contaminates concentration as well as projected timing of next alert.
04	RECOMMENDED ACTIONS Provides a recommended action sequence for Emergency Response Teams.
05	EVENT SUMMARY Provides a summary of an event to include: Location, Start Time, End Time, Duration and Highest Concentration Level. All necessary information for regulatory compliance reporting.

LOGICAL PROGRESSION IN THE AQIS

The purpose of the AQIS is to:

Monitor sensors in a facility for above nuisance, or threshold level sensor signals for a gas contaminant in the monitors range or space.
Provide an alert or alarm status message that annunciates the time, location, concentration, forecast for additional messages and recommended actions.
Provide updated status messages of additional alerts or alarms until event is concluded.

For the purposes of this outline, the gas being monitored is Anhydrous Ammonia. The ammonia system is located in a carbonated beverage production facility. There are three monitored areas or zones:

Filling Room	There are 3 product filling lines each with an ammonia refrigerated product chiller. There are 6 anhydrous ammonia gas monitors in the room.
Equipment Yard	There are 6 compressors in the compressor room. There are 3 anhydrous ammonia gas monitors in the room.
Compressor Room	There is a multi-cell evaporative condenser, an ammonia receiver and a suction trap with transfer system. There are 3 anhydrous ammonia gas monitors in the equipment yard.

*This outline will cover AQIS Alert and Alarm message configuration from Initial Alert to Event Termination.

THE FIRST SCREEN

On the HMI display is the AQIS Dashboard which has one or more Vertical gauges each calibrated to represent the highest level of monitored gas in PPM (Parts Per Million). The gauge is color coded to highlight the current contamination levels in a monitored space or zone.
