The Milwaukee 48-73-8430C Class B Type III PACKOUT First Aid 193-Piece Kit is a jobsite first aid kit built into a PACKOUT organizer case. This is a first aid kit designed for jobsite injury response and organized medical supply storage. If you already run Milwaukee PACKOUT boxes, this kit makes a lot of sense because it keeps emergency supplies in the same system as the tools your crew actually uses. Model Number: 48-73-8430C.

What separates this kit from a generic shop first aid box is the combination of supply count, rating, and case design. It includes 193 essential first aid items and meets ANSI Z308.1-2015 Class B, Type III requirements, which is the kind of standard many contractors, facility teams, and commercial crews need to pay attention to. In practical terms, that means you are getting a kit meant for a wider range of workplace incidents than a light-duty consumer assortment.

The case matters here just as much as the contents. Milwaukee builds this unit with an impact-resistant body, reinforced hinge, and heavy-duty latches, so it is better suited to rough transport than the usual plastic first aid box that cracks, pops open, or ends up with loose contents rolling around the truck. The clear top also helps because you can identify the kit quickly and check supply levels without digging through a cabinet.

For day-to-day use, the no-travel bin seals are a smart detail. Small items stay in their sections instead of mixing together during transport, which saves time when somebody needs gauze, tape, or antiseptic right now. The transparent lid helps keep contents from shifting, and the green first aid stickers make the case easy to spot among red PACKOUT storage on a busy site.

The IP65 rated weather seal is another real-world feature, not just a spec line. Medical supplies do not do you much good if they have been sitting in a damp trailer, getting coated with dust, or rattling around in open storage. The sealed organizer design helps protect bandages, adhesives, antibiotics, and related supplies from rain and debris, making this a better fit for construction, service vehicles, and outdoor work than a standard office kit.

System fit is a big reason to buy this version specifically. The Milwaukee 48-73-8430C Class B Type III PACKOUT First Aid 193-Piece Kit offers modular connectivity with all PACKOUT components. If your crew already stacks organizers, tool boxes, and totes on PACKOUT, you can keep first aid where everyone knows to find it. That is a bigger advantage than it sounds, because emergency gear only works when it is visible, accessible, and consistently returned to the same spot.

Physically, the case is compact enough to ride in a vehicle or stack with other modular storage without eating a lot of room. Milwaukee lists the exterior dimensions at 19.7 inches wide, 15.2 inches deep, and 4.6 inches high, with a listed weight of 8.8 pounds. That low-profile format is useful when you need a serious first aid kit that still stores cleanly on a shelf, in a van, or on top of a PACKOUT stack.

This Milwaukee first aid kit is best for contractors, maintenance teams, facility managers, electricians, plumbers, HVAC crews, remodelers, and serious DIY users who want a real jobsite-ready medical kit instead of a token box with a handful of bandages. If you need ANSI-rated coverage, weather resistance, organized supplies, and PACKOUT compatibility in one package, this is the right version to look at.
