1
Use of Drager Pump & Tubes
2
Preparation
3
Pump Leak Test Insert unopened tube into the socket Squeeze pump completely and release Pump is adequately leak-proof if the end-of-stroke volume indicator has not appeared after 15 minutes Remove tube from socket Press button to reset counter to zero
4
Preparing the Tube Select tube for the measurement required. Follow instructions for use (tube). Insert tip in opening on the lower pump plate; keep it pressed against the ceramic edge while turning it, so that the glass is scored.
5
Pull tube over at an angle until the tip breaks off. Discard broken tip. Open other end of tube in the same way. Insert tube into pump, the arrow must point towards the pump.
6
Making a Measurement Check number of strokes required for the tube. Put forefinger and ringfinger in the middle of the lower pump plate and squeeze completely. Release pump. Evaluate the result. Remove used tube from socket. Flush pump.
7
Carbon Dioxide Tubes Determination of CO2 in air Measuring range – 100 to 3000ppm Number of strokes – 10 Time of measurement – approx. 4 mins Colour change – white to violet
8
Carbon Dioxide (Simple Asphyxiants)
9
Acute Effects Rapid loss of consciousness Coma Anoxic brain injury
10
Chronic Effects Residual anoxic injury
11
Exposure Limits Atmospheric oxygen should > 18% at normal barometric pressure
12
General Considerations Asphyxiants gases are those inhalants that act predominantly by oxygen deprivation. This may occur by simply displacing oxygen from inspired air.
13
Occupational & Environmental Exposure One of confined space exposure (storage tanks or mines) Product of combustion and fermentation processes. Natural volcanic lake release
