Boiler Room Gas Concentration Isopleths at Ceiling Elevation All of the figures that are shown above are for a single instant in time, but as a release occurs the concentrations vary. In order to get a better appreciation of the release characteristics, a video of the modeled release can be created and viewed.Get A Quote
Boiler room gas detection: different alarm thresholds. A gas detection controller for boiler heating systems manages every fixed gas detector and features relays for alarm signals and valves actuators: Level 1: 10 or 15 % of the LEL (lower explosive limit), visual and audible signal with alarm report for fast on-site interventionGet A Quote
Provided standards exist, all alarm settings are based on the following: Low alarms are based on OSHA PEL and/or NIOSH values. High alarms are based on 2 times OSHA PEL values. b. MSHA CO limits are 50 ppm for a low alarm and 100 ppm for a high alarm. c. MSHA NO2 limits are 5 ppm for a high alarm.Get A Quote
