Jobsite readiness and hazard controls · Lesson 3 of 4

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.

A documented method

OSHA's roofing booklet tells employers to plan ahead, so the right equipment, materials and trained workers are on hand.

Safety programs include frequent and regular inspections of job sites, materials and equipment by competent persons (1926.20(b)(2)).

The flow below orders the checks this module covers. Write down each result.

Jobsite readiness sequenceTen numbered steps top to bottom: plan the job, survey the site, choose fall protection, set up access, stage materials, temporary power, hot work controls, heat and weather plan, rescue plan and records, inspect daily then work. Step 3 splits into a low-slope branch, guardrail, net, PFAS, or a warning line plus a second system, or a safety monitor alone on roofs 50 ft wide or less, and a steep branch, guardrail with toeboard, net or personal fall arrest. A dashed loop runs from the last step back to the survey, labelled re-survey.re-survey when conditions changePlan the jobSurvey the siteChoose fall protectionSet up accessStage materialsTemporary powerHot work controlsHeat and weather planRescue plan, recordsInspect daily, then workLow-slope:rail, net, PFAS,line + second system,or monitor alone if50 ft wide or lessSteep:rail with toeboard,net or PFAS12345678910

Ten numbered steps from planning the job to the daily inspection, with a branch at step 3 for low-slope and steep roofs and a loop from stop-work triggers back to the site survey.

1
Plan the job: equipment, materials and trained workers (OSHA 3755)
2
Survey: surface strength, edges, slope, holes, power lines, access and storage (1926.501(a)(2), 1926.416(a)(3))
3
Choose fall protection for each area by slope and width (1926.501(b))
4
Set up access: ladder 3 ft above the landing, foot a quarter out (1926.1053)
5
Stage materials: anything stored in tiers secured, and nothing loose near edges (1926.250(a), 1926.501(c))
6
Temporary power: GFCI or assured grounding program; sound cords (1926.404, 1926.416)
7
Hot work: fire hazards moved or protected, extinguisher at hand (1926.352, 1926.150)
8
Heat and weather plan (NIOSH; OSHA 3755)
9
Rescue plan and training records (1926.502(d)(20), 1926.503)
10
Daily inspection, then work; stop and re-survey when conditions change

Videos for this lesson

What this video shows: OSHA prevention video. Reroofing with guardrails installed on the roof, a worker steps back onto a plastic skylight dome; it breaks and he falls 15 ft. The replay adds a cover that meets OSHA rules. Checked against OSHA's published transcript.

Video: Falls in Construction - Skylights by USDepartmentofLabor, on YouTube. AFS checked its transcript against this lesson.

Glossary

Assured equipment grounding conductor program
The employer's alternative to GFCIs on construction sites: cords and equipment inspected before each day's use and tested at set intervals.
Written certification record
The fall protection training record: the employee's name, the training dates and the trainer's or employer's signature.
Acclimatization
NIOSH's gradual build-up of time in the heat for new and returning workers.
Working length
The length of a ladder along its rails from the foot to the top support; the foot sits about a quarter of it out.
