Hollow Metal Frames AHA (Activity Hazard Analysis / Job Hazard Analysis)
Updated 2026-06-23
A Hollow Metal Frames AHA (Activity Hazard Analysis / Job Hazard Analysis) is the plan that keeps the crew installing hollow metal frames safe from the hollow metal frame handling and installation, from the frame grouting and anchoring, and around the at-height wall opening fall. Hollow metal frames installs hollow metal door/opening frames — combining the hollow-metal-frame-handling and installation hazard, the frame-grouting and anchoring hazard, and the at-height-wall-opening-fall hazard. This guide walks through building a Hollow Metal Frames AHA that names the hollow-metal-frame-handling/installation, frame-grouting/anchoring, and at-height-wall-opening-fall hazards and assigns the handling, grouting, and fall controls that hold up in the field.
Why hollow metal frames needs its own AHA
Hollow metal frames is the installation of hollow metal door/opening frames — the hollow metal frames (the hollow metal (formed steel) frames set into the wall openings for doors and other openings, commonly grouted solid and anchored into masonry, before the door leaves or fill are installed). This continues the doors-and-frames group, focused on hollow metal frames alone. The defining feature is the same as the hollow metal doors and frames but frame-only: the hollow metal frames are steel frames commonly grouted solid and anchored into masonry — so the distinctive hazard is the frame grouting and anchoring (filling the frames with grout — the caustic-cement/dust exposure, and anchoring into masonry — the drilling/silica and fastening), on top of the metal frame handling and the at-height wall-opening work. The hazards combine the hollow-metal-frame-handling and installation (handling and installing the hollow metal frames — the handling, crush, and sharp-edge hazards), the frame-grouting and anchoring (grouting and anchoring the frames — the grout and anchoring hazards), the at-height-wall-opening-fall (working at the openings — the fall hazards), and the eye. The hollow-metal-frame-handling/installation and the frame-grouting/ anchoring justify a dedicated AHA.
Breaking hollow metal frames into steps
The steps for a Hollow Metal Frames AHA follow the work:
- Review the hollow metal frame schedule (safety data)
- Set up opening access and fall protection
- Position and set the hollow metal frames in the openings
- Anchor the frames into the masonry/wall (drilling/fastening)
- Grout the frames solid as required (grout exposure)
- Manage the handling, grouting, and fall hazards
- Complete
Each step carries a hazard, and the hollow-metal-frame-handling/installation, the frame-grouting/anchoring, and the at-height-wall-opening-fall are where the most significant risks concentrate.
The hazards step by step
Hollow-metal-frame-handling and installation
Handling and installing the hollow metal frames — the handling, crush, and sharp-edge hazards. The controls are hollow-metal-frame-handling and installation controls (hollow metal (formed steel) frames — handling them (manual handling, the pinch/crush hazard of the frame members, the sharp formed-metal edges — cut/laceration, and the frames can be long/awkward) and installing them (positioning and setting the frames in the openings — the crush of positioning, and holding/bracing the frames plumb and square — the strain and the frame tipping if not braced)), and the handling/installation controls. The hollow-metal-frame-handling/installation is the primary defining hazard — handling and setting the hollow metal frames carries handling, crush, and sharp-edge hazards. (These follow the material-handling fundamentals.)
Frame-grouting and anchoring
Grouting and anchoring the frames — the grout and anchoring hazards. The controls are frame-grouting and anchoring controls (hollow metal frames are commonly grouted solid (filled with grout/mortar for rigidity and fire rating) and anchored into the masonry/wall — the grouting (mixing and placing cement grout — the caustic-cement/skin and dust exposure, per the grouting controls, and the handling of grout into the frames) and the anchoring (frame anchors/fasteners into the masonry/wall — the fastening and any drilling, with masonry drilling a silica-dust concern)), and the grouting/anchoring controls. The frame-grouting/anchoring is a defining hazard — grouting and anchoring the hollow metal frames carries grout and anchoring hazards. (These follow the grouting and fastening fundamentals.)
At-height-wall-opening-fall
Working at the openings — the fall hazards. The controls are at-height-wall-opening-fall controls (hollow metal frames are set in wall openings throughout the building — a wall opening at height (an upper-floor or elevated opening) is a fall hazard until the frame and fill are installed and the opening is controlled, so fall protection at the openings, opening protection, and safe access), and the fall/opening controls. The at-height-wall-opening- fall is a defining hazard — wall openings are fall hazards. (These follow the fall-protection fundamentals.)
Eye
The eye (metal handling, grout, drilling) carries the eye hazard. The controls are eye protection (hollow metal handling, grout splash, and masonry-drilling debris — full eye protection), and the eye controls. (These follow the eye-protection fundamentals.)

Hollow-metal-frame-handling/installation control and frame-grouting/anchoring control
A Hollow Metal Frames AHA centers on hollow-metal-frame-handling/installation control and frame-grouting/anchoring control. The hollow-metal-frame-handling/installation control addresses the frames — controlled by hollow-metal- frame-handling and installation controls (safe handling, crush/pinch and sharp-edge control, safe setting and bracing). The frame-grouting/anchoring control addresses the grouting and anchoring — controlled by frame-grouting and anchoring controls (grout caustic/dust controls, safe anchoring and drilling with silica control). And the at- height wall-opening fall and eye get fall and eye controls. An AHA built on hollow-metal-frame-handling/ installation control and frame-grouting/anchoring control, with fall controls, addresses the hazards that define hollow metal frames.
From the field: what actually goes wrong
In fourteen years across federal, heavy civil, and industrial projects, hollow metal frames installs the hollow metal (formed steel) frames set into the wall openings for doors and other openings, commonly grouted solid and anchored into masonry, before the door leaves or fill are installed, and its distinctive hazard, like the hollow metal doors and frames, is the frame grouting. The hollow-metal-frame-handling and installation hazard is a primary defining concern — hollow metal frames, so handling them (manual handling, the pinch/crush hazard of the frame members, the sharp formed-metal edges — cut/laceration, and long/awkward frames) and installing them (positioning and setting the frames — the crush of positioning, and holding/bracing the frames plumb and square — the strain and the frame tipping if not braced) are central. The hollow metal frame handling and installation is a defining hazard.
The frame-grouting/anchoring and the at-height-wall-opening-fall are the other defining hazards. On the projects I have run, hollow metal frames are commonly grouted solid (filled with grout or mortar for rigidity and fire rating) and anchored into the masonry/wall, so the grouting (mixing and placing cement grout — the caustic-cement and skin/dust exposure, per the grouting controls, and the handling of grout into the frames) and the anchoring (frame anchors and fasteners into the masonry/wall — the fastening and any drilling, with masonry drilling a silica-dust concern) are central. And the at-height-wall-opening-fall hazard is that hollow metal frames are set in wall openings throughout the building, so a wall opening at height is a fall hazard until the frame and fill are installed and the opening is controlled. The eye hazard rounds it out. The AHA built on hollow-metal-frame- handling/installation control and frame-grouting/anchoring control is the one that protects the hollow-metal-frames crew.
The bottom line
A Hollow Metal Frames AHA names the hollow-metal-frame-handling/installation, the frame-grouting/anchoring, and the at-height-wall-opening-fall hazards with specific controls — hollow-metal-frame-handling and installation controls (safe handling, crush/pinch and sharp-edge control, safe setting and bracing), frame-grouting and anchoring controls (grout caustic/dust controls, safe anchoring and drilling with silica control), and at-height-wall- opening-fall controls (fall protection, opening protection, safe access). The hollow-metal-frame-handling/ installation control and the frame-grouting/anchoring control are the defining concerns. The AHA that manages both is the one that protects the crew.
Frequently asked questions
Why is the frame grouting/anchoring a distinctive hazard?
Hollow metal frames are commonly grouted solid (filled with grout/mortar for rigidity and fire rating) and anchored into the masonry/wall — the grouting (mixing and placing cement grout — the caustic-cement/skin and dust exposure, and the handling of grout into the frames) and the anchoring (frame anchors/fasteners into the masonry/wall — the fastening and any drilling, with masonry drilling a silica-dust concern). Controls are frame-grouting and anchoring controls (grout caustic/dust controls, safe anchoring and drilling with silica control), and the grouting/anchoring controls.
What hollow-metal-frame handling and installation hazards apply?
Hollow metal (formed steel) frames — handling them (manual handling, pinch/crush of the frame members, sharp formed-metal edges — cut/laceration, and long/awkward frames) and installing them (positioning and setting the frames — the crush of positioning; holding/bracing the frames plumb and square — the strain and the frame tipping if not braced). Controls are hollow-metal-frame-handling and installation controls (safe handling, crush/pinch and sharp-edge control, safe setting and bracing), and the handling/installation controls.
What fall hazards apply?
Hollow metal frames are set in wall openings throughout the building — a wall opening at height (an upper-floor or elevated opening) is a fall hazard until the frame and fill are installed and the opening is controlled. Controls are at-height-wall-opening-fall controls (fall protection at the openings, opening protection, safe access), and the fall/opening controls.
What is hollow metal frames?
Hollow metal frames is the installation of hollow metal door/opening frames — the hollow metal frames (hollow metal, formed steel, frames set into the wall openings for doors and other openings, commonly grouted solid and anchored into masonry, before the door leaves or fill are installed). Because handling and setting the hollow metal frames carries handling/crush and sharp-edge hazards, the frames are grouted and anchored (grout/anchoring hazards, with masonry drilling silica), and the wall openings are fall hazards, those hazards apply.
