Jobsite readiness and hazard controls · Lesson 4 of 4

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.

Read the defect

For each defect, record what you saw, the rule it breaks, the fix and the evidence a reviewer will need.

Non-compliant equipment: it is tagged or locked out, or removed from its place of operation, where it is used (1926.20(b)(3)).

Correct and incorrect jobsite set-upsFour pairs, correct on the left and incorrect on the right. Skylight: a secured cover marked HOLE over the opening, against a bare plastic dome. Ladder: rails running 3 ft above the eave with the foot a quarter of the length out, against rails stopping at the eave on a ladder set too steep. Flashing: a long red stick of flashing raised on a line, against a climber carrying the stick up the ladder, a load that could throw them off balance. Power line: a fiberglass ladder set well away from an overhead line after the utility is called, against a metal ladder tipping into the line.CorrectIncorrectSkylight openingLadder to the eaveGetting flashing upNear a power lineHOLEsecured, marked, 2xdome only3 ftfoot 1/4length outstops at eave,too steepraisedon a linecarried up:load canunbalancefiberglass,utility calledmetal laddermoved upright

Four pairs. Skylight: a secured cover marked HOLE, against a bare plastic dome. Ladder: rails 3 ft above the eave with the foot a quarter out, against rails stopping at the eave on a steep ladder. Flashing: the stick raised on a line, against a climber carrying a 10 ft stick that could throw them off balance. Power line: a fiberglass ladder set away from a line, against a metal ladder tipping toward it.

Rules from 29 CFR 1926.501, 1926.502(i), 1926.1053 (including (b)(22): no load that could cause a climber to lose balance) and 1926.416; power-line pair after OSHA 3979 and the OSHA ladder video. OSHA 3979 tells you to know the safe working distance for workers and equipment and to ask the electric company to de-energize and ground the lines; keep ladders and long metal well clear.

Videos for this lesson

What this video shows: OSHA prevention video. A 40 ft metal extension ladder moved upright by one worker falls onto an overhead line; the replay surveys for lines, checks voltages with the utility, uses a fiberglass ladder and two workers carry it horizontally. No clearance distance is given. Checked against OSHA's published transcript.

Video: Electrocution/Work Safely with Ladders Near Power Lines by USDepartmentofLabor, on YouTube. AFS checked its transcript against this lesson.

Glossary

FACE report
A NIOSH or state investigation of a workplace death, with recommendations to prevent the next one.
"Do Not Use" tag
The marking on a defective portable ladder, which is then withdrawn from service until repaired.
Fall protection plan
A site-specific plan by a qualified person, allowed only for leading edge, precast concrete or residential work where conventional protection is infeasible or more hazardous; kept at the job site.
