Annual Medical Gas Testing
EMGS offers annual testing of all components of piped medical gas systems including source equipment, valves, alarm panels and outlets.

All medical gas outlets / inlets will be tested for correct pressure/vacuum readings, flow rates, and particulate matter, leaks, cross connections, pressure drop, and labeling / proper coloring.
Medical Gas Pressure outlets will be sampled and tested for contaminants including total hydrocarbons, halogenated hydrocarbons, total particulate matter, moisture (dew point), carbon dioxide (where applicable), and carbon monoxide (where applicable). Each outlet tested will be purged at a flow rate of 8 SCFM for at least 30 seconds. Random particulate testing will be done at selected end points on each zone through a 0.45 micron filter at a flow rate of 3.5 SCFM for one minute.
EMGS gauge pressures will be compared to line pressure gauges on the zone valves for accuracy and correct labeling will be noted. The final report will list each zone valve in the facility and the area(s) served. EMGS will test medical gas valves and zone valves for leakage using an ultrasonic leak detector.
EMGS gauge pressures will be compared to line pressure alarm gauges on the area alarm panels. Area alarms will be checked and/or tested for all audible and visual signals, high alarm set point, low alarm set point (if available), and correct operating pressures. As per the TJC requirement EMGS will functionally test the sensors for each area alarm (where possible without interrupting gas flow) utilizing the EMGS Area Alarm testing device. The final report will list each area alarm in the facility and the area(s) served; if area alarms are not labeled as to the area served it will be so noted on the final report.
Master alarm testing will be performed where available and where the facility staff and configuration allow it. As per the TJC requirement EMGS will functionally test all pressure switches, lag alarms, dew point, and co alarms, and related manifold / bulk gas alarms. Pressure switches will be tested with an EMGS Master Alarm Testing Device (pictured above). Alarm set points will be adjusted where possible and where needed. Master alarm will be checked and/or tested for all audible and visual signals. EMGS will not disrupt the gas supply in any way during the testing.
Manifolds will be tested for proper alarm functions, bank switchover capability and alternating sequence (if available), correct gauge indication (not calibration), gas leakage, and relief valve operation. Written reports will reflect location, correct manifold operation, and labeling.
Source equipment systems will be checked for code compliance as per NFPA 99, proper suction or pressure delivery, automatic and/or manual alternation, proper voltage, proper amperage draw, oil levels, filter conditions, and unit hours. All valves, intakes / exhausts lines, and pressure switches shall be checked for leakage and proper operation where available.
