JHA for smoke detector 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 smoke detector 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 electric shock from live wiring, falling through a floor opening or void, falling from a ladder and heat stress.

  • Use tool guards and screens to stop flying particles. Engineering
  • Use dust extraction and water to keep dust out of the air. Engineering
  • Keep others out of the area when cutting, grinding or chipping. Administrative
  • Keep an eye wash station or eye wash bottles on site. Administrative
  • Wear safety glasses at all times, goggles for dust and chemicals, and a face shield for grinding. PPE
Medium
4Run cable in the ceiling space, staying on joists
  • Falling through a floor opening or void
  • Heat stress
Critical
  • Cover every hole with a secured cover marked "HOLE" or "COVER" that can hold twice the weight it may carry. Engineering (guarding)
  • Put guardrails with toe boards around stairwells, elevator shafts, floor holes and open edges. Engineering (guarding)
  • Install stairs early and fit temporary handrails as soon as they go in. Engineering
  • 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 lighting good enough to see openings, especially on lower floors and in the evening. Administrative
  • Use a harness clipped to a rated anchor when working right next to an open void. PPE
  • Schedule heavy work for the cooler part of the day. Elimination
  • Provide shade over work and rest areas, and fans or cooling in attics. Engineering
  • Supply cool drinking water close by and drink a cup every 15 to 20 minutes. Administrative
  • Take regular rest breaks in the shade, more often as it gets hotter. Administrative
  • Let new and returning workers build up to full work in the heat over about a week. Administrative
  • Watch each other for dizziness, headache, confusion or stopping sweating. Stop work, cool down and get help. Administrative
  • Have a hot weather plan, including when work stops. Administrative
  • In California, Washington, Oregon and Maryland, follow the state heat illness rule: written plan, shade, water, rest and high-heat procedures. Administrative
  • Wear light, loose, long-sleeved clothing, a hat or brim, and sunscreen. PPE
Medium
5Connect and test every alarm, then clean up
  • Electric shock from live wiring
  • Poor housekeeping and waste
Critical
  • Electric shock from live wiring: see step 2 for the full controls Administrative
  • Order materials to size and send packaging back where you can. Elimination
  • Put dumpsters and waste chutes close to the work. Engineering
  • Clean as you go, and do a full clean up at the end of each day. Administrative
  • Keep exits, stairs and walkways clear at all times. Administrative
  • Stack materials neatly on level ground, away from edges. Administrative
  • Wear gloves when handling waste. PPE

Hazards to watch on smoke detector installation

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

Step 4Heat stressHard work in hot weather or hot attics causes heat exhaustion or heat stroke, which can kill.
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.
Step 4Falling 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 3Eye injuriesFlying chips, dust, chemicals or sparks get into the eye and cause damage or blindness.
Step 3General dustDust from drywall, joint compound, cement and clean up irritates eyes and lungs and makes it hard to see.
Step 3Falling from a ladderThe ladder slips or tips, or the worker overreaches, and they fall onto a hard surface.
Almost certainLikelyPossibleUnlikelyRareHow bad it could be: First aid only to FatalityBA
Highest risk on smoke detector 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 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)?

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 smoke detector installation?

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

Usually Safety-toe boots (ASTM F2413), Safety glasses (ANSI Z87.1), N95 respirator, Rubber insulating gloves, Arc flash PPE (NFPA 70E), Hard hat (ANSI Z89.1), Safety goggles (ANSI Z87.1), Face shield (ANSI Z87.1), Sun protection (sunscreen, hat, long sleeves), Work gloves. The site rules may add more, so check with the general contractor.
