Safety-First™ Vapor Sensor - Labconco Paramount 69632 Series User Manual

Chapter 4: Performance Features and Safety Precautions
Safety-First™ Vapor Sensor
The Safety-First™ Vapor Sensor detects filter saturation in the exhaust to
alert the operator to replace the filters. The early warning provided by the
Safety-First Vapor Sensor provides the user ample time (5-10% remaining
filter life) to complete work in process before replacing the filters. The early
warning signals with an intermittent beep and the LCD display message alerts
the user to replace filters. The final warning signals with a constant alarm
and the LCD display message alerts the user to replace filters. The Safety-
First Vapor Sensor includes a primary and secondary backup sensor for
redundant monitoring. Both sensors detect typical organic vapor solvents,
smoke particulates, ammonia gases, formaldehyde gases and hydrogen
sulfide gases. The Safety-First Vapor Sensor has an optimal detection range
of 1-10 ppm. Typical concentrations tested by Labconco for chemicals in
separate chemical families are listed in order of sensor sensitivity as follows:
Chemical Family
Aldehydes & Ketones Cyclohexanone
Mixture of Aliphatic Gasoline
Hydrocarbons
Particulates Cigarette smoke
Aldehydes & Ketones Acetone
Aromatic Hydrocarbons Toluene
Ethers Methyl Tert-Butyl Ether
Sulfur Compounds Hydrogen Sulfide
Nitrogen Compounds Diethylamine
Esters Ethyl Acetate
Ethers Diethyl Ether
Aldehydes Formaldehyde
Nitrogen Compounds Ammonia Solution
(Ammonium Hydroxide)
Alcohols
Ethyl Alcohol
Acids Acetic Acid
Halogens Chlorobenzene
Alcohols Isopropyl Alcohol
Aliphatic Hydrocarbons Hexane
Alcohols
Methanol
Mineral Acids Hydrochloric Acid
* Important Note: Clean up procedures using alcohols or volatile
chemicals with low filter capacity could saturate the filters quickly.
Important Note: The vapor sensor does not detect mineral acid gases such
as hydrochloric acid, nitric acid, or sulfuric acid and other detector means
such as a mineral acid sensor or interval timed sampling with sampling tubes
must be used.
Chemical Safety Note: The chart above is only a guideline! Frequent
chemical testing or filter monitoring is recommended for other chemicals. If
chemical suitability is ever in question, always work below the acceptable
exposure limit/TWA to maximize both safety and filter performance.
