Industrial Haygene - Lab Report Example The length of the stain discoloration is an indication of the measured substance. The tube is graduated in percentage carboxy hemoglobin therefore readings are done directly from the graduations. The detector tubes measure air contaminants in the concentration range of occupational exposure limits. Their characterization is application dependents as illustrated in figure 2. The measurement assembly comprises of the Drager tube and pump. The gas detector pump delivers a precise volume of sample gas (usually 100mL) while simultaneously pulling it through the detector at a desired rate (figure 3). The pumps can either be short term or long term depending on user applications (Drager 25). They are dependent of external energy sources hence their diverse applications. In order to provide greater maneuverability, an extension hose may be utilized in hard to reach areas. There is a close relationship between the Carbon monoxide content of exhaled air. The respiratory carbon monoxide test is a reliable as well as efficient method for measuring carboxyhemoglobin content of blood (Dragger 38). The aim of this experiment is given a process of determining carbon monoxide concentration. The pump was routinely checked for leaks and suction capacity. Air was blown (exhaled air) into a 1L sampling bag with the aid of a resistance tube. The Drager tube, pump and were connected as in figure 5. The bellows of the Drager pump was then compressed to a maximum level and released. Suction is automatic on release of the bellows. The gas detector pump draws out air from the sample bag into the gas detector tube. Observe the length of the discoloration and read the graduations on the beaker. Carbon monoxide tube produces a light brownish green discoloration. The process was repeated two more times using different gas detector tubes. It is paramount that observations are
