JHA for skylight installation

By SiteSortedBuilt from OSHA standards and guidance · How we write and check theseUpdated

OSHA expects employers to find and control hazards on every job, and many general contractors require a written JHA for skylight installation before you start.

A JHA breaks the job into steps, lists the hazards in each step and the controls that protect the crew, and the crew signs it. The main hazards are falling from a roof edge, electric shock from live wiring, falling through a floor opening or void and falling from a ladder.

Job steps, hazards and controls

#Job stepHazardsRisk beforeControlsRisk after
1Set up roof access and edge protection, and protect the room below from falling debris
  • Falling from a roof edge
  • Falling from a ladder
  • Falling tools and materials
Critical
  • Do what you can from the ground or from a scaffold at the gutter line, for example pre-assemble parts on the ground. Elimination
  • Install edge protection or guardrails on all open roof edges before work starts. Engineering (guarding)
  • Use a perimeter scaffold with handrails and toe boards along the eaves where practical. Engineering
  • Where guardrails cannot be fitted, use fall restraint on certified roof anchors so workers cannot reach the edge. Engineering
  • Low-slope roofs: guardrails, safety nets, personal fall arrest, or a warning line combined with one of these or with a safety monitor (a safety monitor alone only on roofs 50 feet wide or less). Steep roofs: guardrails with toe boards, safety nets or personal fall arrest (29 CFR 1926.501(b)(10), (11)). Administrative
  • Use one safe, controlled access point and keep others off the roof. Administrative
  • Use a platform ladder, mobile scaffold or aerial lift for longer jobs instead of a straight ladder. Substitution
  • Use Type I, IA or IAA ladders in good condition. Tag and remove any damaged ladder. Engineering
  • Falling from a ladder: see step 5 for the full controls Administrative
  • Barricade and sign the drop zone under overhead work so nobody walks beneath. Engineering (guarding)
  • Fit toe boards, kick plates and mesh screens on scaffolds and edges. Engineering
  • Use catch fans, debris netting or covered walkways where people pass below. Engineering
  • Tether hand tools when working at height. Engineering
  • Keep platforms tidy. Do not stack materials near edges or above toe board height. Administrative
Medium
2Mark out the opening, checking for cables, pipes and roof framing in the ceiling space
  • Electric shock from live wiring
  • Heat stress
Critical
  • Isolate the power before any work. Do not work live. Elimination
  • Lock out and tag the disconnecting means with your own personal lock and tag so the circuit cannot be energized (29 CFR 1926.417). Engineering (guarding)
  • Test before you touch: prove dead at the point of work with a tested voltage tester. Engineering
  • Only qualified persons work on or near exposed energized parts. Administrative
  • Check for back feeds from solar, batteries and generators that can keep a circuit live after the main switch is off. Administrative
  • If energized work cannot be avoided, use an energized work permit, a safety observer and insulated tools, following NFPA 70E. Administrative

  • Never remove a cover or guardrail without approval. Put it back straight away. Administrative
  • Inspect covers and barriers daily and after other trades have been through. Administrative
  • Keep blade guards fitted and working, and use the riving knife on table saws. Engineering
  • Use push sticks and clamps, and support long pieces so they do not pinch the blade. Engineering
  • Use a sharp, undamaged blade made for the material. Administrative
  • Stand to one side of the blade line, out of the kickback path. Administrative
  • Let the blade stop fully before reaching in or putting the saw down. Administrative

Hazards to watch on skylight installation

The hazards most specific to this job, and the step where each one comes up.

Step 4Glass handling and breakageGlass panes break while being moved or fitted, causing deep cuts, or heavy panels fall and crush.
Step 1Falling from a roof edgeA worker slips or walks off the edge of a roof or gutter line and falls to the ground.
Step 2Heat stressHard work in hot weather or hot attics causes heat exhaustion or heat stroke, which can kill.
Step 3Falling through a floor opening or voidA worker steps into an open hole, stairwell, elevator shaft or floor opening and falls to the level below.
Step 3Saw cuts and kickbackCircular saws, miter saws and table saws cut fingers and hands or throw material back at the user.
Step 3, 5General dustDust from drywall, joint compound, cement and clean up irritates eyes and lungs and makes it hard to see.
Almost certainLikelyPossibleUnlikelyRareHow bad it could be: First aid only to FatalityBA
Highest risk on skylight installation: Critical before controls (B), down to Medium after controls (A), on the United States 5 by 5 risk matrix (likely and fatality becomes unlikely and serious injury).

What changes on your site

This example covers the job itself. Your site may add more. Add controls for any of these that apply (the builder asks you these as yes or no questions):

  • Will anyone work 6 feet or more above a lower level?
  • Will anyone work on a roof?
  • Is there a skylight, fiberglass panel or other fragile roofing?
  • Will you use a scaffold or rolling tower?
  • Will you use an aerial lift (scissor lift or boom lift)?

Licences and legal requirements in United States

Equipment on this job that needs a licence, ticket or training:

  • Mobile (rolling) scaffold: Erected under a competent person (29 CFR 1926.451)

OSHA requires employers to find and fix hazards and to train workers on them. A JHA breaks the job into steps, lists the hazards in each step and the controls that protect the crew. General contractors often require one before you start.

Rules that apply: 29 CFR 1926 Subpart M; 29 CFR 1926 Subpart X; 29 CFR 1926.501(c); 29 CFR 1926 Subpart K; OSH Act Section 5(a)(1) General Duty Clause; state heat rules where they apply (Cal/OSHA T8 3395, WA WAC 296-62-095, OR OAR 437-002-0156, MD COMAR 09.12.32); 29 CFR 1926 Subpart I.

Why JHAs get rejected

General contractors send documents back for these reasons. This example avoids them, but check yours too.

  • Generic steps such as "work safely" or "use PPE" with no task-specific hazards or controls.
  • No OSHA standards referenced for the hazards that have them, such as fall protection, ladders, scaffolds or silica.
  • No competent person named for fall protection, excavation, scaffolds or silica where those hazards exist.
  • Equipment listed without inspection requirements, and no training listed for the people using it.
  • Respirators listed with no respiratory protection program, medical clearance or fit test.
  • Controls rely only on PPE when engineering controls such as guardrails, wet cutting or extraction are feasible.
  • No crew sign-off, or no date and revision when the job has changed.

Questions

Do I need a JHA for skylight installation?

OSHA expects employers to find and control hazards on every job, and many general contractors require a written JHA for skylight installation before you start.

Who signs the JHA?

The supervisor or competent person who prepared it signs, and every crew member signs to show they were trained on the hazards and controls before the job starts. Many general contractors also sign to accept it.

How long do I keep it?

Keep this JHA on site during the job, and keep it with the training and inspection records for at least 1 year after the job (longer if your state plan or general contractor requires it). OSHA does not set a retention period for JHAs themselves.

What PPE is needed for skylight installation?

Usually Safety-toe boots (ASTM F2413), Personal fall arrest system (harness), Cut-resistant gloves, Safety glasses (ANSI Z87.1), N95 respirator, Sun protection (sunscreen, hat, long sleeves), Hard hat (ANSI Z89.1), Hearing protection (earmuffs or plugs), Work gloves. The site rules may add more, so check with the general contractor.
