Free-Standing Component Systems AHA (Activity Hazard Analysis / Job Hazard Analysis)
Updated 2026-06-23
A Free-Standing Component Systems AHA (Activity Hazard Analysis / Job Hazard Analysis) is the plan for installing free-standing component systems — freestanding modular furniture components — and within systems furniture its distinction from panel systems is the self-supporting components. This AHA (Activity Hazard Analysis / Job Hazard Analysis) is about free-standing component systems.
Why free-standing component systems needs its own AHA
Free-standing component systems are the freestanding modular furniture components that assemble into workstations without a structural panel infrastructure — freestanding desks, storage, and screens that stand on their own and combine into workstations (a panel-free alternative to panel-based systems furniture). They carry the systems-furniture hazards (modular assembly/layout, powered furniture), with distinctions from being freestanding rather than panel-hung. Three things define it. First, the freestanding self-supporting components: the components are freestanding and self-supporting — desks, storage units, and freestanding screens/dividers that each stand on their own (not hung on structural panels like panel-based systems), combined into workstation configurations — so there's the freestanding- component assembly (assembling and placing the self-supporting components into configurations, without the panel infrastructure). Second, the freestanding stability: each freestanding component must be stable on its own — the freestanding desks/storage stable, and freestanding screens and tall storage stable or anti-tip anchored (a freestanding screen or tall storage unit, without a panel structure to brace it, must be stable on its own or anti-tip anchored so it doesn't tip). Third, the freestanding power delivery: power is delivered to the freestanding components differently than panel systems — via floor feeds, base feeds, or power poles to the freestanding units (not through panel raceways) — so there's the freestanding power delivery (coordinating the power to the freestanding components — floor/ base feeds, coordinated with the electrical trade). So the defining points are the freestanding self-supporting components, the freestanding stability, and the freestanding power delivery, on the systems-furniture fundamentals. Free-standing component systems are self-supporting components, each stable, powered via floor/base feeds.
Breaking free-standing component systems into steps
The steps install the free-standing component system:
- Confirm the components, layout, and power delivery from the submittal
- Plan the modular layout of the freestanding components
- Assemble and place the freestanding self-supporting components
- Ensure each component is stable; anchor freestanding screens/tall storage anti-tip where needed
- Coordinate the freestanding power delivery (floor/base feeds) with the trade
- Verify the assembly, stability, and power
The hazards step by step
The freestanding self-supporting components
The components are freestanding and self-supporting — desks, storage units, and freestanding screens/dividers that each stand on their own (not hung on structural panels like panel-based systems furniture), combined into workstation configurations. So there's the freestanding-component assembly: assembling and placing the self-supporting components into configurations (assembling the freestanding desks, storage, and screens, and arranging them into workstations — without the panel infrastructure of panel systems, so each component is a standalone piece placed and combined). So assemble and place the freestanding components into the configurations. The freestanding self-supporting components are standalone pieces combined — no panel infrastructure.
The freestanding stability
Each freestanding component must be stable on its own — because there's no structural panel system to brace the components, each freestanding component (desk, storage unit, screen) must be stable on its own. So the freestanding desks and storage are stable (self-supporting and stable), and freestanding screens and tall storage are stable or anti-tip anchored (a freestanding screen or tall storage unit, without a panel structure to brace it, must be stable on its own base or anti-tip anchored so it doesn't tip). So ensure each freestanding component is stable, and anchor freestanding screens/tall storage anti-tip where needed. The freestanding stability is key — without a panel structure, each component must be stable on its own (or anti-tip anchored).
The freestanding power delivery
Power is delivered to the freestanding components differently than panel systems — not through panel raceways, but via floor feeds (power from floor outlets/boxes), base feeds, or power poles to the freestanding units — so there's the freestanding power delivery: coordinating the power to the freestanding components (floor feeds, base feeds, or power poles bringing power to the freestanding units — coordinated with the electrical trade, since the electrical is handled by the qualified trade). So coordinate the freestanding power delivery (floor/base feeds) with the electrical trade. The freestanding power delivery brings power to the standalone components differently than panels.
The modular layout, finished-space, tools, and systems-furniture fundamentals
The modular layout (per the plan), the finished-space/occupied delivery, the hand-tool use (assembly), eye protection, and the handling apply from the systems-furniture fundamentals.

Where the self-supporting components and freestanding stability define these systems
What distinguishes free-standing component systems within systems furniture (versus panel systems) is the freestanding, self-supporting nature: the components are freestanding (each stands on its own — desks, storage, screens combined into workstations without a panel infrastructure), each must be stable on its own (freestanding stability — screens/tall storage stable or anti-tip anchored, since there's no panel structure to brace them), and power is delivered via floor/ base feeds (not panel raceways). So the free-standing emphasis is the self-supporting components, the freestanding stability, and the freestanding power delivery, on the systems-furniture fundamentals. Where panel systems furniture was panels-and-hung-components, free-standing component systems are standalone self-supporting pieces. Freestanding self-supporting components — ensure each is stable, power via floor/base feeds.
From the field: what actually goes wrong
The free-standing-component issues are the stability and the power. The stability: a freestanding component (especially a freestanding screen or tall storage unit) not stable on its own or not anti-tip anchored, so it tips (without a panel structure to brace it — a tip-over hazard). The power: the freestanding power delivery (floor/base feeds) not coordinated with the electrical trade (electrical hazards). The assembly: components assembled/placed poorly, or pinch injuries. The free-standing-component lessons: ensure each freestanding component is stable on its own (and anchor freestanding screens/tall storage anti-tip where needed — no panel structure to brace them), coordinate the freestanding power delivery (floor/base feeds) with the trade, assemble and place the components per the plan, and protect/coordinate in occupied offices. The freestanding stability and the freestanding power delivery are the concerns.
The bottom line
A Free-Standing Component Systems AHA is a self-supporting-component plan. Free-standing component systems are freestanding modular components (desks, storage, screens that each stand on their own, combined into workstations without a panel infrastructure), each of which must be stable on its own (freestanding screens/tall storage stable or anti-tip anchored — no panel structure to brace them), powered via floor/base feeds (coordinated with the electrical trade, not panel raceways), on the systems-furniture fundamentals (modular layout). Respect the freestanding self-supporting components, the freestanding stability, and the freestanding power delivery, and free-standing component systems are installed safely.
Frequently asked questions
What distinguishes free-standing component systems from panel systems furniture?
The freestanding, self-supporting nature. Free-standing component systems are freestanding modular components — desks, storage, and screens that each stand on their own and combine into workstations without a structural panel infrastructure — versus panel-based systems furniture, where components hang on structural panels. So free-standing component systems are distinguished by the self-supporting components (standalone pieces combined, no panel infrastructure), the freestanding stability (each component stable on its own, since there's no panel structure to brace it), and the freestanding power delivery (via floor/base feeds, not panel raceways). Panel systems hang components on panels; free-standing systems use self-supporting pieces.
Why is freestanding stability a key concern?
Because there's no structural panel system to brace the components — so each freestanding component (desk, storage unit, screen) must be stable on its own. The freestanding desks and storage must be self-supporting and stable, and freestanding screens and tall storage must be stable or anti-tip anchored (a freestanding screen or tall storage unit, without a panel structure to brace it, could tip if not stable on its own base or anti-tip anchored). So ensure each freestanding component is stable, and anchor freestanding screens/tall storage anti-tip where needed. Without a panel structure to provide bracing, the freestanding stability of each component is a key concern.
How is power delivered to freestanding components?
Power is delivered differently than panel systems — not through panel raceways (since there are no structural panels), but via floor feeds (power from floor outlets/boxes), base feeds, or power poles to the freestanding units. So there's the freestanding power delivery: coordinating the power to the freestanding components (floor feeds, base feeds, or power poles bringing power to the standalone units — coordinated with the electrical trade, since the electrical is handled by the qualified trade). So coordinate the freestanding power delivery (floor/base feeds) with the electrical trade. The freestanding components get power via floor/base feeds rather than panel raceways.
Do the systems-furniture fundamentals apply?
Yes. Free-standing component systems are systems furniture, so the fundamentals apply — the modular assembly and layout (assembling/laying out the modular components per the plan) and the powered furniture (here freestanding power delivery). Free-standing component systems emphasize the self-supporting components, the freestanding stability, and the freestanding power delivery on top of these fundamentals. The key contrast with panel-based systems furniture is the absence of a structural panel infrastructure — so each component is self-supporting and must be stable on its own.
