Display Casework AHA (Activity Hazard Analysis / Job Hazard Analysis)
Updated 2026-06-23
A Display Casework AHA (Activity Hazard Analysis / Job Hazard Analysis) is the plan for installing display casework — glazed display cabinets and cases — and within casework its distinctions are the glass display components and the integrated display lighting. This AHA is about display casework.
Why display casework needs its own AHA
Display casework is the glazed display cabinets and cases — retail display cases, museum and exhibit display casework, and glazed display units (casework with glass for displaying merchandise, artifacts, or items). It carries the casework hazards (setting/mounting, secure hanging, leveling/finished fit), with distinctions from being glazed display units. Three things define it. First, the glass display components: display casework has glass — glazed doors, glass panels, and glass shelves for display (so the items are visible) — so there's the glass handling (handling glass panels, doors, and shelves — breakage and sharp-edge hazards, cuts from glass, and the risk of breaking the glass) and the secure glass installation (the glass installed securely in the casework — glazed doors and panels set securely, glass shelves supported, so the glass is secure and safe). Second, the integrated display lighting and electrical: display casework often has integrated lighting (display lighting inside the case to illuminate the displayed items — LED or other display lighting) — so there's the display lighting/electrical (the integrated lighting needs an electrical/low- voltage connection — coordinate, and install the display lighting). Third, the display quality and security: display casework is finished display-quality (a clean, finished display case — the glass clean, the case finished, for a presentation-quality result), and sometimes has security/locking (display cases for valuable retail or museum items often lock or have security — secure locking installed). So the defining points are the glass display components, the display lighting, and the display quality/security, on the casework fundamentals. Display casework is glazed display units with glass, lighting, and display quality.
Breaking display casework into steps
The steps install the display casework:
- Confirm the display casework, glass, lighting, and security from the submittal
- Set and level the display casework (base/units)
- Install the glass components (doors, panels, shelves) securely
- Coordinate the display lighting electrical/low-voltage
- Install any security/locking; clean the glass for display quality
- Verify the secure glass, lighting, and finish; clean up
The hazards step by step
The glass display components
Display casework has glass — glazed doors, glass panels, and glass shelves for display (so the displayed items are visible). So there's the glass handling (handling the glass panels, doors, and shelves — glass breakage and sharp-edge hazards: glass can break, cutting the handler, and broken glass has sharp edges; the risk of breaking the glass during handling/install) and the secure glass installation (the glass installed securely in the casework — glazed doors and panels set and secured in their frames/channels, glass shelves properly supported on their supports, so the glass is secure and safe, not loose or at risk of falling). So handle the glass carefully (cut-resistant gloves, careful handling to avoid breakage) and install the glass securely (doors, panels, shelves secure and supported). The glass display components bring glass handling (breakage/cuts) and secure glass installation.
The integrated display lighting and electrical
Display casework often has integrated lighting — display lighting inside the case to illuminate the displayed items (LED strips, puck lights, or other display lighting) — so there's the display lighting/electrical: the integrated lighting needs an electrical or low-voltage connection (coordinate the electrical/low-voltage with the trade, and install the display lighting per the casework). So coordinate the display lighting's electrical/low-voltage and install the lighting. The integrated display lighting adds the electrical/low-voltage connection.
The display quality and security
Display casework is finished display-quality and sometimes secured. The display quality: a clean, finished display case (the glass clean and clear, the case finished, for a presentation-quality display result — display casework is seen up close and must look finished). The security: display cases for valuable retail or museum items often lock or have security features (secure locking or security installed so the displayed items are secure). So finish the display case to display quality (clean glass, finished appearance) and install any security/locking. The display quality and security reflect that display casework presents and sometimes secures valuable items.
The secure hanging, leveling, eye, and casework fundamentals
The setting/leveling, any secure wall-unit hanging (wall-mounted display units anchored into backing), the finished- space protection, eye protection (glass handling), and the handling apply from the casework fundamentals.
A simple Display Casework AHA structure
| Step | Hazard | Control | Standard |
|---|---|---|---|
| Handle glass components | Glass breakage / sharp edges / cuts | Careful handling; cut-resistant gloves; avoid breakage | OSHA 1926.250 |
| Install glass securely | Glass loose/falls | Set doors/panels/shelves secure and supported | mfr./spec |
| Coordinate display lighting | Electrical / low-voltage | Coordinate electrical/low-voltage with trade | OSHA 1926.416 |
| Install security/locking | Displayed items not secure | Install secure locking/security per spec | spec |
| Finish/clean for display | Poor display quality | Clean glass; finished appearance | general duty |
Where the glass, lighting, and display quality define display casework
What distinguishes display casework within casework is the glazed display: the glass display components (glazed doors, panels, and shelves — glass handling/breakage and secure glass installation), the integrated display lighting (an electrical/low-voltage connection for the display lighting), and the display quality and security (a clean, finished, presentation-quality display case, sometimes secured/locked for valuable items). So the display-casework emphasis is the glass components, the display lighting, and the display quality/security, on the casework fundamentals (setting, leveling, secure hanging). Where standard casework was opaque cabinets, display casework is glazed with glass and lighting for display. Glazed display units — handle the glass safely, install it securely, wire the lighting, finish for display.
From the field: what actually goes wrong
The display-casework issues are the glass and the lighting/finish. The glass: glass panels, doors, or shelves broken during handling (breakage, cuts from broken glass), or glass installed insecurely (loose glazing, unsupported shelves — a hazard). The lighting: the display lighting's electrical improvised rather than coordinated. The finish: the display case not finished to display quality (dirty or scratched glass, poor finish — a poor display result). Plus the security/locking and setting/leveling. The display-casework lessons: handle the glass components carefully to avoid breakage and cuts (cut-resistant gloves), install the glass securely (doors, panels, shelves secure and supported), coordinate the display lighting's electrical/low-voltage, finish the case to display quality (clean glass, finished appearance), and install any security/locking. The glass and the display lighting/quality are the display-casework concerns.
The bottom line
A Display Casework AHA is a glazed-display plan. Display casework is glazed display cabinets — the glass display components (glazed doors, panels, shelves — handle the glass carefully to avoid breakage/cuts, install it securely), the integrated display lighting (coordinate the electrical/low-voltage), and the display quality and security (a clean, finished, presentation-quality case, secured/locked for valuable items), on the casework fundamentals (setting, leveling, secure hanging). Respect the glass handling and secure installation, the display lighting, and the display quality, and display casework is installed safely.
Frequently asked questions
What distinguishes display casework from standard casework?
The glazed display. Display casework is glazed display cabinets and cases — retail display cases, museum display casework, glazed display units — with glass for displaying items. So it's distinguished by the glass display components (glazed doors, glass panels, and glass shelves — glass handling/breakage and secure glass installation), the integrated display lighting (an electrical/low-voltage connection for display lighting), and the display quality and security (a clean, finished, presentation-quality case, sometimes secured/locked for valuable items). Standard casework is opaque cabinets; display casework is glazed with glass and lighting for display.
What are the glass hazards?
Display casework has glass — glazed doors, glass panels, and glass shelves. So there's the glass handling (handling the glass components — glass breakage and sharp-edge hazards: glass can break and cut the handler, broken glass has sharp edges, and there's the risk of breaking the glass during handling/install) and the secure glass installation (installing the glass securely — glazed doors and panels set and secured in their frames, glass shelves properly supported, so the glass is secure and not loose or at risk of falling). So handle the glass carefully (cut-resistant gloves, careful handling to avoid breakage) and install it securely. The glass brings breakage/cut hazards and the need for secure installation.
What about the display lighting?
Display casework often has integrated lighting — display lighting inside the case to illuminate the displayed items (LED strips, puck lights, or other display lighting). So there's the display lighting/electrical: the integrated lighting needs an electrical or low-voltage connection (coordinated with the trade), and the display lighting installed per the casework. So coordinate the display lighting's electrical/low-voltage connection and install the lighting. The integrated display lighting is a distinctive display-casework feature adding an electrical/low-voltage connection.
Do the casework fundamentals apply?
Yes. Display casework is casework, so the fundamentals apply — the cabinet setting and mounting (setting/leveling the display units), the secure hanging (wall-mounted display units anchored into backing), and the leveling/finished fit. Display casework emphasizes the glass display components, the display lighting, and the display quality/security on top of these fundamentals. The finished fit is especially important here since display casework is seen up close and must look presentation-quality, with clean, clear glass.
