They assist in the assessment of workplace contaminant measurement, both personal and background.
3M™ Organic Vapour Monitors are simple and effective devices that collect certain organic vapour type airborne contaminants using the scientific principle of diffusion.
Diffusion is a natural process by which it is known that gases and vapours will flow from a higher concentration (in the workplace air) to a lower concentration (in the base of the monitor). A sorbent pad in the base collects and holds the organic gases and vapours until desorbed for analysis in a laboratory. 3M Monitors have been extensively validated both at 3M and through independent third party sources.
The airborne concentrations measured can be used as part of a Risk Management process to institute suitable controls, including assisting in determination of the type and service life of respiratory equipment appropriate to the contaminants (according to AS/NZS1715). The basic considerations required for sampling with passive type diffusion monitors are covered in AS 2986.2:2003.
3M produces two diffusion monitors for determination of airborne concentration of organic vapours. These are the 3M Organic Vapour monitors 3500 and the 3520. These monitors come in a sealed pull top can, with a shelf life of ~18 months – the expiry date is marked on a label on the base of the can.
Simple and convenient. There are no batteries, pumps or equipment to calibrate.
Easy to use - just clip the monitor to shirt lapel, collar or pocket.
Versatile- can be used for area or source monitoring if sufficient airflow exists.
Comfortable - monitors are small, lightweight and will not interfere with work activities.
Can simultaneously capture a wide range of airborne organic vapours, enabling laboratory identification of type and level of worker exposures.
