Carbon Monoxide Monitoring Presented by: Interscan Corporation Slide 2 SYNONYMS Coal gas Carbon oxide Carbonic oxide Exhaust gas Flue gas Monoxide CARBON MONOXIDE Slide 3 CARBON MONOXIDE IS THE MOST COMMON TOXIC GAS As a product of combustion, it is ubiquitous CO is one of the few toxic gases that can be encountered at home or on the job Colorless and odorless, CO is a silent killer Slide 4 CO HEALTH EFFECTS At 200-300 ppm, can cause fatigue in healthy individuals, and chest pain in those with heart disease. At higher concentrations, can cause impaired vision and coordination; headaches; dizziness; confusion; nausea. Can cause flu-like symptoms (ca. 250 ppm) that clear up when in clean air. At 2000 ppm, can be rapidly fatal Slide 5 TOXICOLOGY Carbon monoxide is an asphyxiant Inhalation of CO causes tissue hypoxia by preventing the blood from carrying sufficient oxygen Carbon monoxide combines reversibly with hemoglobin to form carboxyhemoglobin The reduction in oxygen-carrying capacity of the blood is proportional to the amount of carboxyhemoglobin formed Slide 6 Occupational Exposure Standards Slide 7 OSHA Standards (as of Feb, 2011) The OSHA PEL ( Permissible Exposure Limit, based on an 8-hour time-weighted average) is 50 ppm Special provision for maritime workers/longshoring [29 CFR 1918.94(a)(1)(i))] employees shall be removed from the enclosed space if the CO concentration exceeds a ceiling of 100 ppm. Exception: The ceiling shall be 200 ppm instead of 100 ppm for Ro-Ro operations. Slide 8 ACGIH TLV [Threshold Limit Value] (as of Feb, 2011) TLV-TWA (based on an 8-hour time-weighted average) is 25 ppm Biological Exposure Index (BEI ) is recommended for carbon monoxide Based on percent carboxyhemoglobin saturation in blood, or end-expired CO concentration in alveolar air Slide 9 NIOSH REL [Recommended Exposure Limits] (as of Feb, 2011) TLV-TWA (based on an 8-hour time-weighted average) is 35 ppm Ceiling value of 200 ppm (should not be exceeded at any time) Slide 10 NIOSH IDLH [Immediately Dangerous to Life and Health] (as of Feb, 2011) IDLH: The airborne concentration from which a worker could escape without injury or irreversible health effects, in the event of the failure of respiratory protection equipment. IDLH values are based on effects that might occur as a consequence of a 30-minute exposure. Regardless of the 30-minute basis, if equipment failure occurs, LEAVE THE AREA AT ONCE!! 1200 ppm Slide 11 GRADE D BREATHING AIR Per ANSI / CGA G-7.1.1989 As it pertains to carbon monoxide No more than 10 ppm Slide 12 Applications Engineering Slide 13 AT A MINIMUM, CONSIDER Portable/survey or fixed continuous monitoring requirement? Interfering gases present? Will unit be used/installed in electrically hazardous area? Is data logging needed? Slide 14 Some Carbon Monoxide Monitoring Products Offered By Slide 15 PORTABLE ANALYZER Slide 16 CONTINUOUS MONITORING SYSTEM SINGLE POINT APPLICATION Slide 17 CONTINUOUS MONITORING SYSTEM TWO POINT APPLICATION Slide 18 CONTINUOUS MONITORING SYSTEM MULTI-POINT (THREE OR MORE) APPLICATION Slide 19 For Survey Applications, We Recommend Our Nomad Data Logger 12-bit resolution Models available for 0-100mV, 0-2.5V and 4-20mA inputs Self-contained units also available for temperature, humidity and pH Sampling rate adjustable1 second to 10 hours in 1 second intervals Storage capacity16336 readings Excellent software included Slide 20 Visualize your measurement session with an auto-scaling time history graph Slide 21 Time history graph detail screen Zoomed in on particular portion of the curve Slide 22 Ability To View All Individual Data Points Slide 23 Slide 24 ARC-MAX DATA ACQUISITION, ARCHIVING, AND REPORTING PACKAGE Slide 25 ARC-MAX is designed to meet and exceed all toxic gas regulatory reporting requirements Protect your employeesAND your company! Slide 26 Only ARC-MAX gives you Shift reports, supporting up to four shifts/day, and the shifts can overlap Alarm logs, updated as alarms occur Live and historic trending STEL and TWA tracking, continuously updated Slide 27 ARC-MAX MAIN SCREEN Slide 28 ARC-MAX SHIFT REPORT Slide 29 ARC-MAX TRENDING Slide 30 ARC-MAX ALARM LOG Slide 31 For more information on how Interscan can help you solve your carbon monoxide problems, Visit our website http://www.gasdetection.com
