An exposure limit is a quantity or duration of exposure to a product or substance at which the exposure becomes hazardous. In Comply Plus, exposure limits can be recorded for products represented by SDSs (see SDS Exposure Limits) or individual product ingredients (see Editing an SDS Ingredient).
Exposure limits come in different types, describing limits that apply to various product usages, work environments, or health regulations. Some of the exposure limit types automatically supplied in your system include:
● Ceiling: The concentration of a substance that should never be exceeded during working exposure.
● IDLH (Immediately Dangerous to Life and Health): The concentration of an airborne contaminant at which the contaminant becomes likely to cause death, permanent adverse health effects, and/or inability to escape the contaminated environment.
● TWA (Time-Weighted Average): The concentration to which nearly all workers can be constantly exposed over an 8-hour work-day or 40-hour work-week without adverse health effects.
In addition to these exposure limit types (and others supplied by Sphera), you can create others for use in your corporation. By maintaining an up-to-date list of exposure limit types, you enable users to accurately record exposure limits of all required types.
Note: There is no such thing as a "local" exposure limit type. Any exposure limit type you create—whether from the Corporate site or from a local site—becomes available at every site in the corporation.
To view the corporation's exposure limit types:
Starting at the Application Administration page (How do I get there?), do the following:
● In the menu on the left, under DATA, click Exposure Limits.
The administrative Exposure Limits page opens, showing the name and description of each exposure limit type defined in your system. The icon(s) to the left of each limit type indicate its origin:
● 
Supplied by Sphera; cannot be edited or deleted.
● 
Created by a user in your corporation; can be deleted and edited using these icons (respectively). See below.
If you have permission to manage exposure limit types, see the following topics for details:
● Creating an Exposure Limit Type: Allow users at all sites to record exposure limits of a new type.
● Editing an Exposure Limit Type: Update the name or description of an existing exposure limit type.
● Deleting an Exposure Limit Type: Prevent users at all sites from recording exposure limits of an unwanted type.
