A minimum PPE category level of Category 2 requires the use of a balaclava or sock hood.
Here's a breakdown of why:
PPE (Personal Protective Equipment) categories are established to protect workers from various hazards, with electrical arc flashes being a significant concern in many industries. The level of protection required is determined by the potential hazard and the incident energy exposure.
According to the reference material, Category 2 PPE includes:
- AR (Arc-Rated) long-sleeved shirts and pants or coveralls with a minimum arc rating of 8 cal/cm².
- AR face shield or flash suit hood with a sock hood or balaclava.
Therefore, when wearing an AR face shield or flash suit hood in a Category 2 environment, a balaclava or sock hood is a required component of the PPE ensemble. This is to provide additional protection to the head and neck areas, which can be particularly vulnerable to burns during an arc flash. The balaclava ensures complete coverage and minimizes the risk of exposed skin.
