Concrete JHA: job hazard analysis example and generator
A concrete JHA covers formwork and shoring, rebar, and placing concrete by pump or bucket. It also covers finishing, saw cutting (a silica hazard), stripping forms and cleanup. The main references are 29 CFR 1926 Subpart Q (1926.700–1926.706) and the respirable crystalline silica standard, 1926.1153.
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.
General contractors (GCs) list concrete among the high-risk tasks that need a written JSA (job safety analysis). Expect them to check the shoring inspection, rebar impalement protection, and your silica controls.
Common concrete hazards
- Formwork or shoring collapse during the pour
- Impalement on protruding rebar
- Struck by pump booms and buckets
- Cement burns to skin and eyes
- Respirable crystalline silica when cutting and grinding

Florida job sites
Florida: heat and early pours
Many Florida crews pour at first light to beat the heat. JHABox concrete drafts for Florida addresses add the heat-illness step, and the cement-burn controls assume crews will be sweating in rubber boots and gloves.
Concrete JHA FAQ
Does OSHA require a written concrete 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.
Do I need a written silica plan?
1926.1153(g)(1) requires a written exposure control plan where employees are exposed to respirable crystalline silica under the standard. JHABox lists the plan as a requirement; you still need to write and keep the plan itself.
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.
