First, describe the work and worksite
A two-person crew will apply the specified curing compound to a recently finished outdoor slab on grade with a low-pressure sprayer after the finishing crew releases access. This fictional learning example records planned controls; it supplies no actual inspections or work authorization.
- Product, sprayer, application method and timing come from the project specification and actual product instructions.
- The crew can isolate the treated slab and protect adjoining occupied areas and drainage.
- This example excludes heated enclosures, blankets, elevated slabs and concrete placement.
Questions before work
- Which product hazards and application restrictions are stated on the label and SDS?
- Who releases slab access and protects workers from the treated surface?
- Where will overspray, equipment rinsate and leftover compound go?
Build the analysis one step at a time
What will the worker do? How could someone be harmed? What prevents or reduces that exposure? Who checks the control, and when?
1. Accept the slab and select the product
Hazard: Premature access can damage the slab or cause a fall; an unsuitable compound can introduce chemical hazards.
Control: Foreperson confirms finishing handover and the specified compound. Review label, SDS and application instructions with the crew before opening containers.
Verification: Compare product identification and slab access with the specification and handover.
Why this belongs in the analysis: Product selection changes both the hazard and the work method.
2. Separate the application area
Hazard: Overspray or a slick treated surface can expose pedestrians, vehicles or neighboring trades.
Control: Establish a boundary and controlled route before spraying. Protect drains and nearby surfaces; coordinate occupancy, wind and air intake conditions.
Verification: Crew walks the boundary and confirms affected people know the access restriction.
Why this belongs in the analysis: An outdoor location does not remove drift exposure.
3. Inspect and fill the sprayer
Hazard: Leaks, incompatible seals, splashes or pressurized connections can injure the operator.
Control: Use a sprayer compatible with the compound and follow its filling and pressure limits. Wear protection selected from the actual assessment and SDS. Depressurize before opening or changing fittings.
Verification: Operator checks equipment condition and the specified pressure-release method before filling.
Why this belongs in the analysis: A water sprayer may not be suitable for a chemical compound.
4. Apply from the agreed route
Hazard: Drift, skin contact and slippery footing can injure the crew.
Control: Use the specified nozzle and method without walking into the wet treatment. Maintain the access boundary and stop when wind or drift defeats control. Use assessed ventilation and ignition controls for the product.
Verification: Operator watches drift and footing; helper maintains separation from the safe side.
Why this belongs in the analysis: The operator’s route matters as much as the spray pattern.
5. Stop and manage product residue
Hazard: Residual pressure or incompatible cleaning chemicals can cause splash or an uncontrolled release.
Control: Release pressure as instructed, secure remaining compound and use only the compatible cleaning method. Contain residue and rinsate for the site disposal arrangement.
Verification: Operator confirms zero unsafe pressure before opening and identifies each waste container.
Why this belongs in the analysis: Shutdown must address both pressure and chemical residue.
6. Maintain the access restriction and hand over
Hazard: Another crew can slip or contact compound before the specified return-to-service conditions are met.
Control: Leave the treated area identified and controlled. Give the receiving supervisor the actual product restrictions and required release criteria; remove the boundary only after authorized handover.
Verification: Foreperson records the product, treated area and access decision with the receiving crew.
Why this belongs in the analysis: Application completion is not the same as unrestricted access.
What does a useful control look like?
| Needs improvement | More useful for this scenario |
|---|---|
| Be careful around the equipment. | Use a sprayer compatible with the compound and follow its filling and pressure limits. Wear protection selected from the actual assessment and SDS. Depressurize before opening or changing fittings. |
| Check the area before starting. | Foreperson confirms finishing handover and the specified compound. Review label, SDS and application instructions with the crew before opening containers. |
Decisions that change the analysis
Does a water-based label eliminate chemical review?
No. Review the actual product hazards and exposure controls. A formulation description alone does not select gloves, eye protection, ventilation or disposal methods.
What must be recorded before this example is used on a job?
Replace the scenario with the actual work, identify additional hazards with the crew, and record the applicable instructions, responsible people, inspection findings, unresolved actions and required authorization. A planned verification is not an inspection result.
Agree when the crew will pause
- Product changes or instructions conflict with the planned method.
- Wind, occupancy, drift or ignition conditions change.
- Leaks, unsafe footing or missing waste containment appear.
After a pause, correct the condition, reassess the work, and obtain required authorization before restarting. Keep unresolved actions visible.

1. Describe your work and site
2. Work through each task
Describe an observable step, how someone could be harmed, and the control that acts on that hazard. Identify who checks it and what evidence is needed.
3. Record changes, checks, and open actions
Walk the work area, review with the crew, and resolve missing controls. Follow the required approval process. This tool does not judge completeness, verify signatures or authorize work.

Training needs to confirm
- Actual product hazards, spray equipment and pressure release.
- Exposure first aid, spill limits and treated-area handover.
Confirm applicable qualifications, task instruction and actual training evidence for the people assigned. Related toolbox talks support crew discussion; they do not establish competence.
Common questions
Can this be used as a JSA?
Use the Task | Hazard | Control structure if it meets the employer’s format. Adapt the boundaries, controls, verification and records to the actual job.
Does this provide a completed USACE AHA?
No. Use the project’s required AHA process, risk method, supporting fields and acceptance requirements. The existing formwork AHA explains the additional structure.
Are these resources part of a paid course?
This walkthrough, browser draft builder and downloads are free public resources, separate from Academy course enrollment.
