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 Concrete Drilling and Chipping JHA
Walk through the job in order. Use these possible hazards, planned controls and checks to start a conversation about your actual work.
01Verify the intended penetration or removal
Possible hazards: A drill or chisel can strike electricity, plumbing, a tendon, or structural reinforcement, causing shock, release of energy, flooding, or structural damage.
Planned controls: The responsible project personnel reconcile drawings, surveys, scanning where appropriate, and field conditions before releasing marked work locations. Identify the other side of the surface and establish exclusion there if needed. Do not treat one scan as a guarantee that every service has been found; resolve uncertainty before drilling.
Check before work: Match marked locations and depth limits to the actual clearance information and responsible authorization.
02Choose separate dust controls for drilling and chipping
Possible hazards: Both tasks can release respirable silica, but one tool's control arrangement may not satisfy the requirements for the other.
Planned controls: For Table 1 handheld drilling, use the specified shroud or cowling and dust collector with required airflow, filtration, and filter cleaning; use a HEPA vacuum for hole cleaning. For chipping, select the applicable water-delivery or shroud-and-extraction arrangement. Indoor or enclosed Table 1 chipping requires APF 10 respiratory protection for either duration category.
Check before work: The silica competent person verifies the task row, equipment, and ventilation. Required respirators need an employer program, including medical evaluation and appropriate fit testing, before use.
03Inspect and set up tools and the work area
Possible hazards: A damaged lead, loose bit, missing handle, or unstable stance can cause shock, ejected parts, or loss of control.
Planned controls: Follow tool instructions for bit selection, retention, auxiliary handles, guards, and power supply. Remove damaged equipment from service. Route cords and hoses away from travel and water, use the site's required electrical protection, and provide a stable working position. Separate bystanders from chips and tool movement.
Check before work: Confirm the bit is retained, handles are secure, extraction operates, and the intended stance avoids overreaching.
04Drill the approved holes
Possible hazards: A binding bit can rotate the tool suddenly; flying fragments, sustained force, noise, and vibration can injure workers.
Planned controls: Maintain the manufacturer's grip and stance, use compatible reaction-control features, and apply only the force needed for the tool to cut. Keep the dust shroud effective as depth changes. Use assessed eye, hearing, and other protection. Stop for binding, unexpected resistance, changed material, or breakthrough outside the approved limit.
Check before work: Confirm dust capture remains effective and the operator is not compensating for a worn bit with excessive force.
05Chip within the approved surface-removal limits
Possible hazards: Fragments can strike people; an uncontrolled chisel can remove unintended material, and repeated vibration can affect hands and arms.
Planned controls: Use a tool and bit appropriate to the limited removal, maintain the selected dust system, and direct fragments away from people. Keep the tool supported and avoid forcing it from an awkward posture. Select lower-vibration methods where practical and plan exposure reduction using actual equipment and duration; do not rely on anti-vibration gloves alone.
Check before work: Confirm the removal boundary, tool condition, respiratory controls, and opportunities to reduce continuous trigger time.
06Clear holes and change bits or collection containers
Possible hazards: Unexpected tool operation can cut or entangle a worker; hot bits and released dust create additional exposure.
Planned controls: Disconnect or otherwise isolate the tool under its instructions before bit changes and maintenance, allow hot parts to cool, and use the specified handling method. Clean holes using the required HEPA vacuum arrangement and applicable anchor instructions. Empty dust containers by the manufacturer's controlled method; avoid blowing dust into the room.
Check before work: Confirm isolation, compatible replacement parts, and a container-change method that maintains exposure controls.
07Clean and hand over the finished work
Possible hazards: Settled dust can become airborne; fragments and unprotected penetrations can affect the next trade.
Planned controls: Use HEPA vacuuming or suitable wet cleaning. Do not dry sweep or use compressed air where it could contribute to silica exposure except under the standard's limited permitted conditions. Remove fragments, protect new openings, and report unexpected voids or service discoveries. Obtain separate verification for the actual anchor installation or structural work.
Check before work: Confirm residue, waste, openings, and unresolved findings are addressed before reopening the area.
Example scope and starting conditions
This fictional example covers drilling approved anchor holes and removing small nonstructural surface projections from conventional concrete at ground level inside an unfinished room. Battery or electric rotary-hammer tools are used with compatible dust controls. The work excludes post-tensioned concrete, structural demolition, overhead breaking, unknown coatings, and core drilling through floors. The supervisor must first establish that the proposed penetration and removal are permitted. The example does not supply a drilling permit, structural clearance, or an anchor installation design.
- Identify concrete construction, embedded services, reinforcement, any tendons, coatings, and the space beyond the surface. Uncertain information is a reason to stop and investigate.
- Record the hole locations, diameter and depth, removal limits, actual tool, work duration, and whether the space is enclosed. These details affect both service-strike and silica-control decisions.
- Coordinate with occupants and other trades, establish a controlled work area, and identify power supplies, ventilation, and dust-container disposal routes.
- The employer's silica competent person implements the written exposure-control plan. Select the applicable Table 1 method or the alternative exposure-assessment route for each task.
Know when to pause
- Pause for unknown reinforcement, suspected tendons, services, voids, unexpected coatings, or a changed penetration depth.
- Reassess a different tool, indoor versus outdoor location, work duration, failed extraction, or dust affecting another crew.
- Use a separate analysis for overhead breaking, core drilling, structural removal, confined spaces, or elevated access.
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.
Decisions that change the plan
The drill's vacuum fails but only two holes remain. May work continue with a mask?
Stop the dust-producing work. Restore the selected control method or have the employer establish another valid method before continuing; a mask alone does not replace failed engineering controls.
Can the same respiratory decision be copied from drilling to indoor chipping?
No. Table 1 treats these as different tasks. Verify each row, including the indoor chipping respiratory requirement and the employer's respiratory-protection program.

Task-by-task control and verification rationale
Verify the intended penetration or removal
Hazard: A drill or chisel can strike electricity, plumbing, a tendon, or structural reinforcement, causing shock, release of energy, flooding, or structural damage.
Control: The responsible project personnel reconcile drawings, surveys, scanning where appropriate, and field conditions before releasing marked work locations. Identify the other side of the surface and establish exclusion there if needed. Do not treat one scan as a guarantee that every service has been found; resolve uncertainty before drilling.
Verification: Match marked locations and depth limits to the actual clearance information and responsible authorization.
Why this belongs in the analysis: Dust controls do not address the potentially greater consequence of penetrating an unknown service or structural element.
Choose separate dust controls for drilling and chipping
Hazard: Both tasks can release respirable silica, but one tool's control arrangement may not satisfy the requirements for the other.
Control: For Table 1 handheld drilling, use the specified shroud or cowling and dust collector with required airflow, filtration, and filter cleaning; use a HEPA vacuum for hole cleaning. For chipping, select the applicable water-delivery or shroud-and-extraction arrangement. Indoor or enclosed Table 1 chipping requires APF 10 respiratory protection for either duration category.
Verification: The silica competent person verifies the task row, equipment, and ventilation. Required respirators need an employer program, including medical evaluation and appropriate fit testing, before use.
Why this belongs in the analysis: A shop vacuum and an optional nuisance mask do not establish a compliant exposure-control method.
Inspect and set up tools and the work area
Hazard: A damaged lead, loose bit, missing handle, or unstable stance can cause shock, ejected parts, or loss of control.
Control: Follow tool instructions for bit selection, retention, auxiliary handles, guards, and power supply. Remove damaged equipment from service. Route cords and hoses away from travel and water, use the site's required electrical protection, and provide a stable working position. Separate bystanders from chips and tool movement.
Verification: Confirm the bit is retained, handles are secure, extraction operates, and the intended stance avoids overreaching.
Why this belongs in the analysis: Inspection should lead to a usable setup, not simply a check mark beside the tool's name.
Drill the approved holes
Hazard: A binding bit can rotate the tool suddenly; flying fragments, sustained force, noise, and vibration can injure workers.
Control: Maintain the manufacturer's grip and stance, use compatible reaction-control features, and apply only the force needed for the tool to cut. Keep the dust shroud effective as depth changes. Use assessed eye, hearing, and other protection. Stop for binding, unexpected resistance, changed material, or breakthrough outside the approved limit.
Verification: Confirm dust capture remains effective and the operator is not compensating for a worn bit with excessive force.
Why this belongs in the analysis: The response to a change in resistance is investigation, not simply a harder push.
Chip within the approved surface-removal limits
Hazard: Fragments can strike people; an uncontrolled chisel can remove unintended material, and repeated vibration can affect hands and arms.
Control: Use a tool and bit appropriate to the limited removal, maintain the selected dust system, and direct fragments away from people. Keep the tool supported and avoid forcing it from an awkward posture. Select lower-vibration methods where practical and plan exposure reduction using actual equipment and duration; do not rely on anti-vibration gloves alone.
Verification: Confirm the removal boundary, tool condition, respiratory controls, and opportunities to reduce continuous trigger time.
Why this belongs in the analysis: Moving one operator to another dusty task may not meaningfully reduce either vibration or inhalation exposure.
Clear holes and change bits or collection containers
Hazard: Unexpected tool operation can cut or entangle a worker; hot bits and released dust create additional exposure.
Control: Disconnect or otherwise isolate the tool under its instructions before bit changes and maintenance, allow hot parts to cool, and use the specified handling method. Clean holes using the required HEPA vacuum arrangement and applicable anchor instructions. Empty dust containers by the manufacturer's controlled method; avoid blowing dust into the room.
Verification: Confirm isolation, compatible replacement parts, and a container-change method that maintains exposure controls.
Why this belongs in the analysis: Maintenance and hole cleaning can bypass the controls that protected the worker during drilling.
Clean and hand over the finished work
Hazard: Settled dust can become airborne; fragments and unprotected penetrations can affect the next trade.
Control: Use HEPA vacuuming or suitable wet cleaning. Do not dry sweep or use compressed air where it could contribute to silica exposure except under the standard's limited permitted conditions. Remove fragments, protect new openings, and report unexpected voids or service discoveries. Obtain separate verification for the actual anchor installation or structural work.
Verification: Confirm residue, waste, openings, and unresolved findings are addressed before reopening the area.
Why this belongs in the analysis: A clean-looking tool does not demonstrate that the room or newly drilled connection is ready for use.
Compare control wording
| Needs improvement | More useful for this scenario |
|---|---|
| Silica: provide dust masks. | Identify the drilling or chipping Table 1 row, verify the compatible control equipment, and implement the required respiratory program where respirators are specified. |
| Hidden services: scan the wall. | Combine appropriate locating information with drawings and field checks, identify limits and authorization, and stop where uncertainty remains. |
Common questions
Is visible dust the only measure of silica exposure?
No. Respirable silica may be present without an obvious cloud. Use the applicable specified controls or exposure assessment rather than judging exposure by appearance alone.
Does the completed JHA authorize drilling into a structural member?
No. Structural and service clearance, permits, design details, and required site authorization remain separate decisions.
