TYPE P -ANSI CLASS 2 and 3 refers to workers previously covered by ANSI/ISEA 207-2011, includes the Type R occupational environments, but “provides additional options for emergency responders, incident responders and law enforcement who have competing hazards or require access to special equipment.”
