Jobsite readiness and hazard controls
The federal construction rules a flashing crew meets on the roof: edges, holes, warning lines, fall arrest, ladders, power lines, heat and hot work. A documented readiness method with worked examples, then how to spot, fix and record common jobsite defects.

Jobsite readiness and hazard controls: principles and terminology
Why the roof runs under the federal construction rules, the words those rules use, the 6 ft trigger for fall protection, and what this module does and does not cover.
You will be able to: Define edges, holes, openings, low-slope and steep roofs, roofing work, competent and qualified persons and fall arrest terms, state the 6 ft trigger, and state who is responsible and the limits of this module.

Jobsite readiness and hazard controls: materials, standards and design constraints
The numbers inside each control: guardrail heights and loads, warning line distances and build, safety monitor rules, cover ratings, fall arrest limits, ladder set-up, metal near power lines, heat and weather.
You will be able to: Identify the numeric criteria for guardrails, warning lines, safety monitors, covers, fall arrest and ladders, and the constraints set by roof slope, roof width, power lines, heat and weather.

Jobsite readiness and hazard controls: methods and worked application
A step-by-step readiness method, then worked examples: fall protection and a warning line for a coping job, a ladder to an eave, a skylight cover, anchors, temporary power, torch soldering and a new hire in the heat.
You will be able to: Apply a documented readiness method to a coping job on a low-slope roof, recording assumptions, units and inspection points for fall protection, ladders, covers, anchors, power, hot work and heat.

Jobsite readiness and hazard controls: defects, verification and case study
Common jobsite defects and their fixes, two NIOSH fatality investigations involving sheet metal work, what a 10 ft stick of flashing can reach, and the records to keep for review.
You will be able to: Diagnose jobsite readiness defects at skylights, warning lines, ladders, power lines, fall arrest, power and hot work, explain corrective options, and document the evidence a reviewer needs.

Practical task
Build a jobsite readiness packet for replacing the coping along one 120 ft side of a 120 ft x 80 ft low-slope roof with a 24 in parapet, a skylight 20 ft in from the coping, a 16 ft eave for ladder access and an overhead service line near the ladder spot.
Hand in
- A decision rationale: the fall protection chosen for the coping crew and for everyone else on the roof, each with its 29 CFR paragraph
- A marked-up plan sketch: edges, the warning line around all sides of the work area, flags, the two-line access paths from the ladder spot and the staging or hoisting area, the skylight cover or guardrail and the overhead line
- An assumptions sheet with units: slope, parapet height, roof width, ladder geometry, cover load, anchorage load and the propane cylinder size, each labelled regulation, assumed or maker value
- A daily readiness checklist for the job, grouped as edges and holes, fall arrest, ladders, electrical, materials, hot work, people and weather
- A defect analysis for one defect found on the first morning: what was seen, the rule, the fix and the evidence kept
Rubric
| Criterion | Meets the standard when |
|---|---|
| Rules | Every choice cites the 29 CFR paragraph or the OSHA, NIOSH or maker source it comes from, and no AFS practice is claimed. |
| Fall protection | The parapet is treated as an unprotected edge, the warning line goes around all sides of the work area with two-line access paths to the ladder and the staging or hoisting area, the crew beyond the line has a second system, and a monitor is not used alone on the 80 ft wide roof. |
| Calculations | Warning line run and flags, ladder length and foot distance, cover load and anchorage load are worked with units and match the rules. |
| Power lines | The service line is identified before work, the utility is contacted, and ladders and long metal pieces are kept away from it. |
| Records | The packet lists the training certification records, tags and dated inspection results a reviewer will ask for. |
