Review on Recent Developments of Fluorescent Oxygen and ...

Abstract: Oxygen and carbon dioxide sensors are involved in many chemical and biochemical reactions. Consequently, considerable efforts over years have been devoted to discover and improve suitable techniques for measuring gas concentrations by optical fiber sensors. Optical gas sensors consist of a gas-sensitive dye entrapped in a matrix with a high permeability to gas. With such sensors…

Carbon Dioxide (CO2) Safety Program

Carbon dioxide (CO2) is a “sleeper hazard;” very little information outside scientific literature has been published to help facilities understand CO2 health effects and control CO2 exposures. This Carbon Dioxide Safety Program is designed to fill this gap. Breathing concentrations of 30% CO2, even with 70% oxygen, leads to unconsciousness in 30 seconds Your facility may have been doing ...
