A hard hat is head protection that guards the head against impacts and falling objects. It also helps protect the head from blows and from contact with energized electrical conductors. In higher arc-flash categories, wear the hard hat with an arc-rated or flame-resistant hard hat liner and an arc-rated face shield or arc flash suit hood. Battery storage install procedures list the hard hat as required PPE along with safety glasses, hearing protection, suitable gloves and leather footwear.
<!-- review notes
- sentence 3: support check: partial - Higher categories list hard hat with hard hat liner (AN/AR, FR liner) and face shield or suit hood, but passages don't say to wear them together on the hat, and Cat 3-4 list only the suit hood, not a face shield.
- sentence 4: support check: partial - u1 shows a PPE list with hard hat and safety glasses, but the battery-storage install procedure context, hearing protection, gloves and footwear in that procedure aren't shown; arc-flash tables list them but are not install procedures.
- sentence 4: review: partial - The install-procedure PPE tables list a hard hat with safety glasses, hearing protection, gloves and leather footwear, but the passages never say these are battery storage procedures.
