JHA for rolling scaffold

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 rolling scaffold 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 height, scaffold collapse or fall from scaffold, falling tools and materials and lifting and carrying heavy loads.

Job steps, hazards and controls

#Job stepHazardsRisk beforeControlsRisk after
1Check all parts and the ground, and look up for power lines
  • Contact with overhead power lines
  • Scaffold collapse or fall from scaffold
Critical
  • Ask the utility to de-energize, move or insulate the lines before work starts. Elimination
  • Use non-conductive (fiberglass) ladders near any power lines. Substitution
  • Mark the safe distance with flags, tape or warning lines and keep all equipment and people outside it. Engineering (guarding)
  • Keep equipment at least 10 feet from lines up to 50 kV once the utility confirms the voltage, more for higher voltages, and 20 feet when the voltage is unknown (29 CFR 1926.1408). Administrative
  • Use a dedicated spotter whenever equipment moves or raises anything near lines. Administrative
  • Treat all lines as energized. If equipment touches a line, the operator stays in the cab and everyone else keeps well away. Administrative
  • Scaffold is built, moved and taken down under the supervision of a competent person. Engineering
  • Fit guardrails, mid rails and toe boards on every platform more than 10 feet above a lower level, or use personal fall arrest (29 CFR 1926.451(g)(1)). Engineering
  • Scaffold collapse or fall from scaffold: see step 4 for the full controls Administrative
Medium
2Build to the instructions with outriggers and guardrails
  • Scaffold collapse or fall from scaffold
  • Falling from height
Critical
  • Use mobile scaffolds only on firm, level ground with casters locked, and guy, tie, brace or fit outriggers once the height is more than 4 times the base width (29 CFR 1926.451(c)(1)). Never move one with anyone on it. Engineering
  • Every worker on the scaffold is trained by a qualified person (29 CFR 1926.454). Administrative
  • Scaffold collapse or fall from scaffold: see step 4 for the full controls Administrative
  • Do the work from the ground where you can, for example pre-assemble on the ground or use extension poles. Elimination
  • Install guardrails or edge protection on all open edges before work starts. Engineering (guarding)
  • Use a scaffold, mobile work platform or aerial lift instead of working off a ladder. Engineering
  • Where edge protection is not practical, use a fall restraint or fall arrest system on a rated anchor point. Engineering
  • Provide fall protection at 6 feet or more and train workers to recognize fall hazards (29 CFR 1926.503). Administrative
  • Have a rescue plan so a worker hanging in a harness can be brought down within minutes. Administrative
  • Wear a full body harness with a shock-absorbing lanyard, clipped on at all times when using fall arrest. PPE
Medium
3Lock the wheels before climbing, climb only on the inside
  • Scaffold collapse or fall from scaffold
  • Falling from height
Critical
  • A competent person inspects the scaffold before each shift and after anything that could affect it (29 CFR 1926.451(f)(3)). Administrative
  • Do not overload platforms. Know the rated load (light, medium or heavy duty) and stack materials over the legs, not mid-span (29 CFR 1926.451(f)(1)). Administrative
  • Scaffold collapse or fall from scaffold: see step 4 for the full controls Administrative
  • Falling from height: see step 2 for the full controls Administrative
Medium
4Never move it with anyone or anything on it
  • Scaffold collapse or fall from scaffold
  • Falling tools and materials
Critical
  • Scaffold is built, moved and taken down under the supervision of a competent person. Engineering
  • Fit guardrails, mid rails and toe boards on every platform more than 10 feet above a lower level, or use personal fall arrest (29 CFR 1926.451(g)(1)). Engineering
  • Use mobile scaffolds only on firm, level ground with casters locked, and guy, tie, brace or fit outriggers once the height is more than 4 times the base width (29 CFR 1926.451(c)(1)). Never move one with anyone on it. Engineering

  • A competent person inspects the scaffold before each shift and after anything that could affect it (29 CFR 1926.451(f)(3)). Administrative
  • Do not overload platforms. Know the rated load (light, medium or heavy duty) and stack materials over the legs, not mid-span (29 CFR 1926.451(f)(1)). Administrative
  • Never remove ties, braces, guardrails or planks. Only the erection crew alters the scaffold, under the direction of the competent person (29 CFR 1926.451(f)(7)). Administrative
  • Wear a hard hat and safety boots on and around the scaffold. PPE
  • 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
  • Lower materials with a hoist, chute or rope. Never throw or drop anything down. Administrative
  • Wear a hard hat anywhere objects could fall. PPE
Medium
5Dismantle in reverse order and store parts
  • Lifting and carrying heavy loads
High
  • Plan to avoid carrying: have materials delivered, and old items picked up, as close as possible to where they are used. Elimination
  • Use lighter or smaller loads: order smaller bags and shorter lengths, and drain or break down old items before moving them. Substitution
  • Use trolleys, pallet jacks, hoists, vacuum lifters or plant instead of carrying by hand. Engineering
  • Use a two-person lift for anything heavy, long or awkward. Plan the route first and clear it. Administrative
  • Keep the load close, back straight and no twisting. Turn with your feet. Administrative
  • Rotate tasks and take breaks on long lifting jobs. Administrative
  • Wear gloves for grip and safety boots to protect your feet. PPE

Hazards to watch on rolling scaffold

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

Step 1, 2, 3, 4Scaffold collapse or fall from scaffoldA scaffold that is badly built, overloaded or altered collapses or tips, or a worker falls from an unguarded platform.
Step 1Contact with overhead power linesA ladder, aerial lift, crane, dump truck or long length of material touches or gets close to an overhead line and electrocutes people.
Step 2, 3Falling from heightA worker falls 6 feet or more from an edge, platform or opening to a lower level and is badly hurt or killed.
Step 4Falling tools and materialsTools, materials or debris fall from above and hit someone working or walking below.
Step 5Lifting and carrying heavy loadsLifting, carrying, pushing or twisting with heavy or awkward loads strains the back, shoulders or knees.
Almost certainLikelyPossibleUnlikelyRareHow bad it could be: First aid only to FatalityBA
Highest risk on rolling scaffold: 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 use a ladder or stepladder?
  • Will anyone work on a roof?
  • Is there a skylight, fiberglass panel or other fragile roofing?
  • Will you use an aerial lift (scissor lift or boom lift)?
  • Was the building built before 1981?

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 1926.1408 and 1926.416; 29 CFR 1926 Subpart L; 29 CFR 1926 Subpart M; 29 CFR 1926.501(c).

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 rolling scaffold?

OSHA expects employers to find and control hazards on every job, and many general contractors require a written JHA for rolling scaffold 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 rolling scaffold?

Usually Safety-toe boots (ASTM F2413), Hard hat (ANSI Z89.1), Work gloves, High-visibility safety apparel, ANSI/ISEA 107 Class 2 or 3 (Type R near roadways), Safety glasses (ANSI Z87.1). The site rules may add more, so check with the general contractor.
