You can work with a limited number of PPE (Personal Protective Equipment) levels (clothing class). Although NFPA has defined hazard risk categories 0, 1, 2, 3, and 4 for energized work, some companies have standardized on only two types of PPE levels (such as HRC# 2 and 4). For example, HRC #2 PPE is used for any work up to NFPA HRC # 2 (up to 8 cal/cm2) and HRC #4 is used for incident energy between 8 and 40 cal/cm2.
Figure 1: PPE Levels
You can customize your PPE levels using the standard library. If you do not want to include a certain level of PPE class in your standard PPE levels, you can delete that row. For example, if you want to have only HRC #2 and 4, you can delete HRC # 1 and 3. Any arc flash incident energy falling in the HRC 1 or 3 will be reported as being in HRC 2 or 4 respectively. See figure below.
Figure 2: Deleting PPE Rows
HRC #: This is the hazard risk category number as per NFPA 70E.
MINIMUM Energy (cal/cm2): This is the minimum cal/cm2 corresponding to the selected PPE Level Text on the right. To remove any PPE Level from your standardized PPE level, delete this cell. For example, in the figure above, PPE Level 1 is deleted. Therefore, to incorporate the incident energy between 2 and 4 cal/cm2 to PPE Level #2, the MINIMUM Energy value corresponding to PPE Level #2 must be modified to 2 cal/cm2.
PPE Level Text: PPE level (clothing class) to display in one-line, text reports, labels and work permits. This corresponds to the standardized PPE levels.
Description: Description of clothing class. You can add or modify the text. This text is used in the labels and work permits.
