The following sections highlight some types of equipment that may be used for sampling and detection of biological agents. A. Surface/Bulk Sampling Swabs Swabs have been used frequently when sampling surface areas for the presence of biological agents. Bioaerosol monitors can be used in assessing sick-building syndrome, or buildings which may have source exposures to molds and bacteria which may be exacerbating or causing illness to the occupants. Consult the instruction manual before calibration, and ensure that the calibration gas is introduced at the proper pressure and flow rate, using the appropriate regulator and adaptors. Interference from other gases can be a problem. When the temperature is more than 35°C and the air is dry, evaporative cooling may be improved by air movement, although this improvement will be offset by the convective heat.
Ludlum Model 2360 with 43-93 Alpha/Beta Scintillator The Ludlum Model 2360 is a survey meter capable of measuring and discriminating between α and β radiations. It is fitted with a Ludlum 43-93 alpha/beta scintillation detector. Scheduling of work (during cooler parts of shift, cleaning and maintenance during shut-downs, etc.) Cool rest areas (including shelter at outdoor work sites)? Heat monitoring program? American Industrial Hygiene Association (AIHA). 1975. Heating and Cooling for Man in Industry. 2nd ed. The unit will be cleaned as part of the annual calibration service. Agar Plates Agar plates, also known as «sticky plates,» can be used to sample a surface by contacting the plate directly to the surface. Some interfering compounds can result in false positive readings. In other cases, the sensor can be damaged, or «poisoned» by exposure to certain compounds, in which case it will need to be returned to the CTC for sensor replacement.
Circulating air is the most highly effective, as well as the most complicated, personal cooling system. By directing compressed air around the body from a supplied air system, both evaporative and convective cooling are improved. Luminometer: A luminometer operates similarly to a fluorometer, except that it will detect the presence of adenosine triphosphate (ATP) in a sample. ATP is another component of a cellular organism, thereby indicating a biological material. The color change is read in terms of either the length of stain generated inside the tube or the degree of color change. Will a cart be needed for moving the instrument around? Heat exhaustion should not be dismissed lightly, however, for several reasons. Important considerations for use of detector tubes include measurement accuracy, limits of detection, interferences, temperature and humidity, shelf life, and the time period for which the color stain is stable after the sample is drawn.
