JHA for hardwood floor installation

By Safety PaperworkBuilt 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 hardwood floor 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 fire from hot works, saw cuts and kickback, wood and MDF dust and loud noise.

Job steps, hazards and controls

#Job stepHazardsRisk beforeControlsRisk after
1Clear the room and agree access with occupants
  • Working in an occupied home or building
  • Slips and trips
Medium
  • Plan noisy, dusty or risky work for when the building is empty. Elimination
  • Close off the work area with barriers, plastic sheeting or locked doors, and put up signs. Engineering (guarding)
  • Keep fire exits and paths clear at all times. Administrative
  • Tell occupants before you turn off power, water or gas, and before noisy or dusty work. Administrative
  • Lock away tools, chemicals and materials each day, out of reach of children. Administrative
  • Clean up dust and debris at the end of each day. Administrative
  • Plan walkways and keep them clear of materials, hoses and leads. Elimination
  • Run cords and hoses overhead on hooks or stands, or along walls, not across walkways. Engineering
  • Fill or cover holes, and lay boards or mats on muddy access paths. Engineering
  • Clean up offcuts, packaging and spills as you go, not at the end of the day. Administrative
  • Keep work areas, stairs and access paths well lit. Administrative
  • Wear safety boots with good grip, laced up. PPE
Low
2Cut boards with dust extraction
  • Saw cuts and kickback
  • Wood and MDF dust
  • Loud noise
High
  • 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

Hazards to watch on hardwood floor installation

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

Step 2, 4Wood and MDF dustSawing and sanding lumber, MDF and treated wood makes fine dust that causes asthma, skin problems and some cancers.
Step 3Nail gun injuriesA nail gun fires by accident, or a nail goes through the lumber or ricochets and hits the user or someone nearby.
Step 5Flammable liquids and gasesGasoline, solvents, thinners and propane catch fire or explode when vapor reaches a spark, flame or hot surface.
Step 6Fire and emergenciesA fire, injury or other emergency happens and workers cannot get out, raise the alarm or get first aid in time.
Step 4Fire from hot worksSparks and heat from welding, grinding or flame torches set fire to timber, insulation, rubbish or fuel nearby.
Step 1Working in an occupied home or buildingResidents, staff or children wander into the work area and get hurt, or the work blocks exits or cuts off power or water while people are inside.
Almost certainLikelyPossibleUnlikelyRareHow bad it could be: First aid only to FatalityBA
Highest risk on hardwood floor installation: Critical before controls (B), down to Medium after controls (A), on the United States 5 by 5 risk matrix (possible 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 use a ladder or stepladder?
  • Will anyone work on a roof?
  • Is there a skylight, fiberglass panel or other fragile roofing?
  • Will you use a scaffold or rolling tower?

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 hardwood floor installation?

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

Usually Safety-toe boots (ASTM F2413), Knee pads, Safety glasses (ANSI Z87.1), N95 respirator, Hearing protection (earmuffs or plugs), Work gloves, Welding gloves, Face shield (ANSI Z87.1), Coveralls, Chemical-resistant gloves, Safety goggles (ANSI Z87.1), Half-face respirator (P100 cartridges). The site rules may add more, so check with the general contractor.
