Scaffolding JHA: job hazard analysis example and generator

A scaffolding JHA follows the scaffold from start to finish. It covers planning and power-line clearance, the base and mudsills (boards under the feet), and erection by a competent person (someone who can identify the hazards and is authorized to correct them). It then covers planking, guardrails, access, the pre-shift inspection, use, and dismantling. The references are in 29 CFR 1926 Subpart L (1926.450–1926.454), which also covers aerial lifts.

Draft only. Every JHA is a draft and must be reviewed by a competent person for the specific site before work begins. JHABox is not affiliated with OSHA or the US Department of Labor.

Scaffolding (1926.451) is number 4 on OSHA’s preliminary fiscal year 2026 list of most-cited standards. General contractors (GCs) typically ask for a written JSA (job safety analysis) for large scaffold erection.

Common scaffolding hazards

Falls from platforms more than 10 ft up
Scaffold collapse from poor footing, overloading or missing ties
Falling tools and materials
Contact with overhead power lines
Boom lift tip-over and ejection

Florida job sites

Florida: wind, lightning, and storm prep

Exposed scaffolds are a hazard in Florida thunderstorms and during tropical storm watches. JHABox scaffold drafts include a stop-work-in-high-winds control and a reinspection after any event that could affect the scaffold, as 1926.451(f)(3) requires.

Scaffolding JHA FAQ

Does OSHA require a written scaffolding JHA?

Federal OSHA has no construction standard that requires a document called a “JHA” (job hazard analysis). You still have to meet the specific 29 CFR 1926 standards for the work and run the accident-prevention program in 1926.20(b). General contractors (GCs), owners, and the US Army Corps of Engineers (USACE) often require one. USACE calls it an Activity Hazard Analysis.

How often must a scaffold be inspected?

1926.451(f)(3) requires a competent person to inspect scaffolds and scaffold components for visible defects before each work shift and after any occurrence that could affect structural integrity.

Can I hand this straight to my general contractor?

Not without review. Every JHABox document is a draft. A competent person (someone who can identify the hazards and is authorized to correct them) has to check it for that site, adjust it to real conditions, and sign it before work starts. JHABox is not affiliated with OSHA.

Is the Spanish version included?

Yes. Pick Spanish on the build form and the whole document comes out in Spanish, including the hazard table, personal protective equipment (PPE) list, and crew sign-off sheet. A paid document includes both languages.
