Rather than implement a common change out schedule across all workers, the indicator allows filters used in appropriate environments to be changed based on individual work hours, exposure levels, breathing patterns and environmental conditions.
Using the indicator
The 3M Service Life Indicator can be used to complement your current filter change schedule. You must change your filter at the normally scheduled interval or when the ESLI indicates, whichever occurs first. In some cases you can use the ESLI as a primary method to determine filter change, replacing your current change schedule method. To find out if the 3M Service Life Indicator may be used as the primary method for determining your filter change-out schedule:
1) Perform exposure monitoring to quantify the organic vapour exposure levels in your work place. Visit 3M.eu/PPESafety for information on 3M™ Organic Vapour Monitors
2) Enter the monitoring results in the 3M™ Select and Service Life Software 3M.eu/SLS If the ESLI is not applicable as a primary method, it may still be used to complement your current filter change schedule.
*Please see the 6000i Series User Instructions or the 3M™ Select Life Software (3M.com/ServiceLifeSoftware) to determine if these filters are appropriate for your work environment.
