70E Table 130.7(C)15(c) Personal Protective Equipment is the table used for the PPE Categories method. In that Table PPE 1 goes to 4 cals, PPE 2 goes to 8 cals, PPE 3 - 25 cals and PPE 4 - 40 cals. Category 2 is good for 8 calories, but anything larger can be used for a lower incident energy rating, so a 25-cal PPE can be used for Cat 2. |

Thank you for your reply, So, a cloth is marked with 25 cal/cm and 2 CAT. Which one is relevant? |

I needed confirmation that I did indeed need to replace the protective clothing. Thank you for the time you have spent on this topic Sincerely Tibor |
