Step 1 of 4 · Working draft
Your job
Tell Jenkins what you’re planning and where the work will happen. Use the actual job details.
Use the published example’s suggestions when they fit your task, or write your own steps. These are planned controls, not verified worksite conditions.
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.
Walk through the plan with the people doing the work. Resolve missing controls and agree who checks them. Moving to the next step does not approve the work.
Confirm people, equipment and emergency arrangements
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.

Your Masonry Remedial Damp-Proof Course Injection JHA
Walk through the job in order. Use these possible hazards, planned controls and checks to start a conversation about your actual work.
011. Release diagnosis and the remedial course
Possible hazards: Treating the wrong water source or an unsuitable wall can leave dampness unresolved and conceal a building defect.
Planned controls: Restoration lead checks the specialist diagnosis, surveyed sound solid-brick construction and issued course layout. Confirm accepted course interfaces with walls, floors and returns. Require actual US project and supplied-product acceptance. Hold penetrating water, condensation, structural distress or uncertain voids for disposition; do not select the method from a damp stain alone.
Check before work: Lead records the diagnosis, matched wall and accepted continuity detail.
022. Prepare safe drilling and product-use holds
Possible hazards: Drilling can strike a service or spread silica; using an unverified product can expose workers without usable hazard instructions.
Planned controls: Investigate services and materials, mark released locations and control the far-side penetration area. Prepare the drill, bit and exposure controls with stable access and residue containment. Before opening product, verify current supplied technical instructions, SDS and project acceptance. Retain the use hold for missing documents; the old foreign SDS is no substitute.
Check before work: Lead verifies drilling clearance, exposure readiness and resolved pre-use documentation holds.
033. Drill and inspect the prescribed hole line
Possible hazards: A wrong depth, missed mortar course or concealed void can interrupt treatment and damage retained masonry.
Planned controls: Drill only the accepted course and geometry under the actual wall-specific instructions, maintaining the selected dust controls and safe bit path. Record hole condition and inspect continuity at corners, returns and any planned transitions. Remove residue by the permitted method. Stop for unexpected voids, services, breakout or unsuitable mortar; do not extend the hole or invent additional positions to solve a mismatch.
Check before work: Installer records hole locations, condition and resolved course/return findings before filling.
044. Match cream and prepare the applicator
Possible hazards: An unidentified cartridge, damaged nozzle or uncontrolled discharge can cause contact exposure and incomplete treatment.
Planned controls: Match the specified product, packaging, condition and applicator to current supplied instructions. Establish ventilation, protection, washing and spill controls from the actual current SDS and assessment, without borrowing old overseas exposure or first-aid criteria. Prepare the package/nozzle by its instructed method, avoiding sharp-tool and discharge paths. Use no dilution, substitution or improvised pressure equipment.
Check before work: Operator verifies product identity, permitted applicator setup and actual protection/response readiness.
055. Fill the accepted course under controlled placement
Possible hazards: An obstructed hole or rushed nozzle withdrawal can leave an unfilled section or discharge cream onto the worker.
Planned controls: Place cream through the manufacturer’s instructed nozzle and withdrawal method within the accepted course layout. Keep the tip and discharge directed into the released hole and maintain controlled hand positions. Verify filling evidence and material use; cartridge count alone is insufficient. Hold obstruction, loss of containment or a changed hole condition; obtain technical disposition before refilling or changing the course.
Check before work: Installer records treated holes, continuity findings and any held or incomplete positions.
066. Protect treatment and hand over drying restrictions
Possible hazards: Premature covering, moisture bridging or an undocumented untreated return can defeat the barrier and mislead occupants.
Planned controls: Complete instructed hole closeout, contain chemical/drilling residue and secure product storage. Transfer course locations, incomplete areas and environmental observations for review. Follow the specialist’s drying and reinstatement plan, preserving floor/return details and covering holds. Generic drying time or an installation-day reading cannot authorize replastering.
Check before work: Receiving lead confirms treatment records and the separate drying/reinstatement responsibilities.
Example scope and starting conditions
A restoration crew will install a specified remedial damp-proof course in sound solid brick with independently diagnosed rising damp. The accepted plan releases the horizontal mortar course, borehole geometry and continuity details. Drilling and selected Dryzone cream placement use ground-level positions in an unoccupied ventilated bay. The treated course remains identified for separately planned drying and reinstatement. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- A responsible specialist distinguishes rising damp from penetrating water, condensation or active leakage and accepts this method for the actual wall. Current US project and supplied-product acceptance are required; overseas certification is not assumed to establish US compliance.
- Verify supplied current technical instructions and SDS before use. The reviewed February 2024 application datasheet and 2018 overseas SDS are research context; they establish no current US classification, product acceptance or field authorization.
- Masonry-restoration coverage is partial: this accepted solid-brick remedial course only. Structural crack bonding, hollow-anchor adhesive, rubble/voided walls, hazardous-material removal, confined spaces, replastering and moisture-diagnosis services are excluded.
Know when to pause
- Diagnosis, sound solid-brick construction, US project acceptance or actual current supplied instructions/SDS cannot be verified.
- Drilling exposes services or voids, the mortar/hole condition differs, dust controls fail or product containment is lost.
- Course continuity is unresolved, an unapproved product/method is proposed or covering would precede the drying/reinstatement release.
After a pause, correct the condition, reassess the work, and obtain required authorization before restarting.

For managers
Does the team have what it needs to carry out the plan? Give the crew time, equipment and support, and make it clear who will resolve anything that is missing.
Manager checks and supporting resources
Confirm the people doing the work have the time, equipment, information and support to carry out the plan. Agree who checks the controls and who resolves open actions.
Questions to resolve before work
- What actual investigation identifies rising damp and releases this mortar course?
- How will borehole and corner/return continuity be verified for this wall construction?
- Which current supplied instructions and SDS permit product use, and what later drying/reinstatement holds apply?
Training and qualifications to confirm
- Accepted damp-proof-course installation instruction covering diagnosed wall suitability, released drilling, hole/return continuity and controlled cream placement.
- Construction silica and chemical handling assessment using actual current SDS, safe applicator use, spill containment and drying-status handover.
Confirm the actual training evidence for the assigned people. A toolbox talk does not establish competence.
Decisions that change the plan
Does this duplicate crack injection or masonry stitching?
Concrete epoxy injection bonds a designated crack; helical-bar stitching reinforces retained masonry with bars and grout. This installs a diagnosed capillary-moisture barrier along a mortar course without a structural repair claim. The waterproof-coating draft treats a wall face and pressure interface rather than an internal horizontal course.
What must the crew record for actual use?
Record the actual work boundary, governing documents, responsible people, acceptance criteria, control findings and unresolved actions. Communicate restrictions and obtain required project authorization; this fictional example records no completed inspection or installed-control acceptance.

Task-by-task control and verification rationale
1. Release diagnosis and the remedial course
Hazard: Treating the wrong water source or an unsuitable wall can leave dampness unresolved and conceal a building defect.
Control: Restoration lead checks the specialist diagnosis, surveyed sound solid-brick construction and issued course layout. Confirm accepted course interfaces with walls, floors and returns. Require actual US project and supplied-product acceptance. Hold penetrating water, condensation, structural distress or uncertain voids for disposition; do not select the method from a damp stain alone.
Verification: Lead records the diagnosis, matched wall and accepted continuity detail.
Why this belongs in the analysis: A remedial moisture barrier follows diagnosis rather than replacing it.
2. Prepare safe drilling and product-use holds
Hazard: Drilling can strike a service or spread silica; using an unverified product can expose workers without usable hazard instructions.
Control: Investigate services and materials, mark released locations and control the far-side penetration area. Prepare the drill, bit and exposure controls with stable access and residue containment. Before opening product, verify current supplied technical instructions, SDS and project acceptance. Retain the use hold for missing documents; the old foreign SDS is no substitute.
Verification: Lead verifies drilling clearance, exposure readiness and resolved pre-use documentation holds.
Why this belongs in the analysis: Safe preparation and chemical authorization require different evidence.
3. Drill and inspect the prescribed hole line
Hazard: A wrong depth, missed mortar course or concealed void can interrupt treatment and damage retained masonry.
Control: Drill only the accepted course and geometry under the actual wall-specific instructions, maintaining the selected dust controls and safe bit path. Record hole condition and inspect continuity at corners, returns and any planned transitions. Remove residue by the permitted method. Stop for unexpected voids, services, breakout or unsuitable mortar; do not extend the hole or invent additional positions to solve a mismatch.
Verification: Installer records hole locations, condition and resolved course/return findings before filling.
Why this belongs in the analysis: A row of visible holes does not prove a continuous acceptable treatment path.
4. Match cream and prepare the applicator
Hazard: An unidentified cartridge, damaged nozzle or uncontrolled discharge can cause contact exposure and incomplete treatment.
Control: Match the specified product, packaging, condition and applicator to current supplied instructions. Establish ventilation, protection, washing and spill controls from the actual current SDS and assessment, without borrowing old overseas exposure or first-aid criteria. Prepare the package/nozzle by its instructed method, avoiding sharp-tool and discharge paths. Use no dilution, substitution or improvised pressure equipment.
Verification: Operator verifies product identity, permitted applicator setup and actual protection/response readiness.
Why this belongs in the analysis: Water-based packaging does not remove the need for a current chemical review.
5. Fill the accepted course under controlled placement
Hazard: An obstructed hole or rushed nozzle withdrawal can leave an unfilled section or discharge cream onto the worker.
Control: Place cream through the manufacturer’s instructed nozzle and withdrawal method within the accepted course layout. Keep the tip and discharge directed into the released hole and maintain controlled hand positions. Verify filling evidence and material use; cartridge count alone is insufficient. Hold obstruction, loss of containment or a changed hole condition; obtain technical disposition before refilling or changing the course.
Verification: Installer records treated holes, continuity findings and any held or incomplete positions.
Why this belongs in the analysis: Hidden material distribution must be supported by the actual installation evidence.
6. Protect treatment and hand over drying restrictions
Hazard: Premature covering, moisture bridging or an undocumented untreated return can defeat the barrier and mislead occupants.
Control: Complete instructed hole closeout, contain chemical/drilling residue and secure product storage. Transfer course locations, incomplete areas and environmental observations for review. Follow the specialist’s drying and reinstatement plan, preserving floor/return details and covering holds. Generic drying time or an installation-day reading cannot authorize replastering.
Verification: Receiving lead confirms treatment records and the separate drying/reinstatement responsibilities.
Why this belongs in the analysis: Course installation and building drying are different stages with different acceptance needs.
Compare control wording
| Needs improvement | More useful for this scenario |
|---|---|
| Every damp wall needs injected cream. | Confirm rising damp, wall suitability and the complete accepted course/return detail before drilling. |
| The old overseas SDS says enough; open the cartridge. | Hold use until the actual supplied current SDS, technical instructions and US project/product acceptance are verified. |
Common questions
Can this example be used as a JSA?
Adapt the Task | Hazard | Control sequence to the employer’s JSA and actual worksite. Name control checkers and record findings; this fictional example supplies no completed inspection or authorization.
What changes if the project requires an AHA?
Use the governing AHA format, risk method, records and acceptance process. The published formwork AHA illustrates that structure. Add actual competencies, inspections and reviews; renaming a JHA does not complete them.
