Integrated Door Assemblies AHA (Activity Hazard Analysis / Job Hazard Analysis)
Updated 2026-06-23
An Integrated Door Assemblies AHA (Activity Hazard Analysis / Job Hazard Analysis) is the plan for setting complete, factory-built door units — frame, leaf, hardware, and sometimes glazing already assembled — into the opening as one piece, and that single fact reshapes the whole risk profile: instead of the staged, piece-by-piece hang of a loose door and frame, you're rigging and landing one heavy, tall, awkward assembly. This AHA (Activity Hazard Analysis / Job Hazard Analysis) is about handling a unit, not a door.
Why integrated door assemblies needs its own AHA
An integrated door assembly arrives as a finished unit — the frame with the leaf already hung, hinges and often the lockset and closer mounted, and in many cases the sidelite or vision glazing already installed. The point of the product is speed and quality in the shop; the consequence on site is that the whole thing lands in one move. That changes the hazard from the incremental crush of hanging a leaf (metal/wood door AHAs) to the concentrated hazards of moving and setting a single large mass: it's heavy (frame plus leaf plus hardware plus any glass, all at once), it's tall and top-relevant (the assembly's center of gravity and its tendency to rack or tip while being maneuvered upright into an opening), and it's fragile in specific spots (pre-mounted hardware and pre-installed glazing that a careless set can damage or shatter). The defining hazards are the rigging/handling of the whole unit and the crush/tip while landing it in the opening. If the crew treats an integrated unit like a loose door, they'll try to carry and wrestle a load that should be rigged.
Breaking integrated door assemblies into steps
The steps are a set, not a build:
- Confirm the assembly weight, dimensions, and glazing from the submittal
- Plan the move and lift matched to the whole-unit weight
- Protect the pre-mounted hardware and any glazing during the move
- Maneuver the unit upright and into the opening (tip/rack control)
- Shim, plumb, and anchor the frame with the unit supported
- Release support only when the frame is anchored and load-bearing
- Adjust the pre-hung leaf and hardware, check operation
The hazards step by step
Rigging and handling the whole unit
The assembly's combined weight is the first hazard, and it's easy to underestimate because a "door" doesn't sound like a rigging job. A pre-hung hollow-metal unit with a fire leaf and sidelite glazing can be a several-hundred- pound single piece, and it's not just heavy but bulky — long frame legs, an offset center of gravity, and glass that makes it both heavier and more fragile. Match the handling to the real submittal weight: material lift, cart, or mechanical handling for anything past a safe team-carry, planned path with the width and door swings checked so the unit isn't stuck and manhandled halfway, and rigging points that don't load the glazing or bend the frame. Carrying an integrated unit by hand because it's "just a door" is the setup for a drop.
Crush and tip while landing it in the opening
Setting the unit is the sharp moment: a tall assembly has to be brought upright and eased into the opening, and while it's being maneuvered it can rack, tip, or swing, with the crew's hands and feet around a heavy frame in a confined opening. Fingers get caught between frame and jamb, feet get caught under a frame leg, and a tipping unit can pin someone against the opening. Control the unit upright with enough crew or mechanical support, keep hands off the frame-to-jamb interface until it's positioned, keep feet clear of the leg landing zone, and don't release any support until the frame is shimmed, plumb, and anchored enough to stand on its own.
Damage to pre-mounted hardware and glazing (which becomes a hazard)
The factory hardware and glazing are pre-installed, so a rough set can shear a closer, bend a hinge, or crack a lite — and a cracked pre-installed lite in a unit being muscled into place is a laceration source, not just a quality defect. Protect the glazing and hardware in the move, and treat any glass in the assembly with the glazing cautions: a lite that cracks during the set has to be dealt with as broken glass.
Eye protection and anchoring debris
Anchoring the frame means drilling and fastening into the surround. Eye protection during anchoring, and dust control if drilling masonry or concrete (silica).
A simple Integrated Door Assemblies AHA structure
| Step | Hazard | Control | Standard |
|---|---|---|---|
| Plan the move | Underestimated unit weight | Read whole-unit weight from submittal; match lift/cart | OSHA 1926.251 |
| Maneuver upright | Tip / rack pinning crew | Enough crew or mechanical support; controlled upending | OSHA 1926.250 |
| Land in opening | Frame-to-jamb pinch / foot crush | Hands off jamb interface; feet clear of leg landing | mfr. procedure |
| Anchor frame | Unsupported unit falling | Shim, plumb, anchor before releasing support | OSHA 1926.501 (opening) |
| Handle glazed unit | Cracked lite laceration | Protect glazing; treat cracked glass as broken glass | OSHA 1926.95 |
Where the unit weight and the landing intersect
The two defining hazards are one continuous event: the same heavy, bulky unit that needed rigging to move is the one being brought upright into a tight opening, so the drop zone and the pinch zone are the same space at the same time. The control that ties them together is not releasing any support until the frame is genuinely anchored — the window where the unit is up but not yet fixed is exactly where a tip or a slip becomes a crush. Keep the mechanical support or the crew on it until it stands on its own.
From the field: what actually goes wrong
The integrated-unit failure is the crew that plans for a door and gets a monolith. A pre-hung, pre-glazed unit shows up, the paperwork says "door," and two people go to carry it the way they'd carry a loose leaf and frame — and it's four hundred pounds of frame, fire door, closer, and sidelite glass in one piece. Either they can't hold it and it goes down (cracking the glazing and endangering feet), or they get it to the opening and then can't control it upright, and it racks and pins a hand against the jamb while someone tries to shim under load. The whole thing is prevented by reading the submittal weight, rigging the move, and not releasing support until the frame is anchored. The product was built in the shop to save field labor — the safety trade is that you now handle its full weight at once, and that has to be planned for.
The bottom line
An Integrated Door Assemblies AHA is a rigging-and-set plan, not a door-hang plan. Because the frame, leaf, hardware, and glazing arrive as one heavy, bulky, fragile unit, the controls are matching the move to the real whole-unit weight, controlling the assembly upright into the opening without racking or tipping, keeping hands and feet out of the frame-to-jamb landing zone, and holding support until the frame is anchored and load-bearing. Plan it as the rigging job it is and the speed benefit of the pre-assembled unit is safe to collect.
Frequently asked questions
Why can't we handle an integrated door unit like a normal door?
Because it isn't a door — it's the whole assembly (frame, hung leaf, mounted hardware, often glazing) in one piece, which can weigh several hundred pounds and is bulky and top-heavy. A loose door and frame are hung incrementally; an integrated unit lands in one move, so it needs a rigging plan and mechanical handling for anything past a safe team-carry. Treating it as "just a door" is how crews end up wrestling a load they should have rigged.
What's the most dangerous moment setting an integrated assembly?
Bringing it upright into the opening. A tall unit being maneuvered can rack, tip, or swing with the crew's hands and feet around a heavy frame in a tight opening — fingers between frame and jamb, feet under a frame leg, or the unit pinning someone against the opening. Control it upright with enough support, keep hands off the frame-to-jamb interface and feet clear of the leg landing, and don't release support until it's shimmed, plumb, and anchored.
The unit has glazing already installed — does that change anything?
Yes. Pre-installed glass makes the unit heavier and more fragile, and a lite that cracks while the unit is being muscled into place becomes a laceration hazard, not just a defect. Protect the glazing during the move, rig so the glass isn't loaded, and if a lite cracks during the set, handle it as broken glass.
How is this different from the doors and frames AHA?
The doors and frames AHA builds the opening up in stages — set the frame, then hang the leaf, then hardware. The integrated assembly does all of that in the shop and lands as one piece, so the hazard shifts from incremental crush to whole-unit rigging and a single high-stakes set. If you're assembling in place, that's the doors-and-frames AHA; if you're landing a finished unit, this rigging focus is the fit.
