JHA for window glass replacement

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 window glass replacement 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 glass handling and breakage, public entering the work area, lifting and carrying heavy loads and falling from a ladder.

Job steps, hazards and controls

#Job stepHazardsRisk beforeControlsRisk after
1Make the area safe and keep people away from broken glass
  • Glass handling and breakage
  • Public entering the work area
High
  • Use suction lifters, glass trolleys or a glazing robot for large panes. Engineering
  • Store glass upright on racks and secure it. Never lay it flat or lean it loosely. Engineering

  • Use two or more people for large panes, and clear the carry route first. Administrative
  • Mark new glass with tape or stickers so nobody walks into it. Administrative
  • Clean up broken glass straight away into a marked container. Administrative
  • Wear cut-resistant gloves, arm guards, safety glasses and safety boots. PPE
Medium
4Fit and bead the new glass
  • Falling from a ladder
  • Hazardous chemicals
High
  • 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
  • Set extension ladders at a 4 to 1 angle on firm, level ground, secured, and reaching 3 feet above the landing. Engineering
  • Use ladders only for short, light work. Do not carry heavy or awkward loads up a ladder. Administrative
  • Keep three points of contact and your belt buckle between the stiles. Do not overreach. Administrative
  • Do not stand on the top three rungs of an extension ladder or the top step of a stepladder. Administrative
  • Check the ladder before each use: feet, rungs, side rails and locks. Administrative
  • Wear non-slip safety boots with clean soles. PPE
  • Choose the least harmful product that does the job, for example water-based instead of solvent-based. Substitution
  • Use chemicals in well-ventilated areas, or use fans and extraction in closed rooms. Engineering
  • Read the Safety Data Sheet (SDS) and labels before use, following OSHA Hazard Communication. Administrative
  • Keep chemicals in labeled containers. Never pour them into drink bottles. Administrative
  • Store chemicals away from heat, food and drink, and keep products that react with each other apart. Administrative
  • Have eye wash and a spill kit nearby, and wash hands before eating. Administrative
  • Wear chemical-resistant gloves and safety glasses or goggles as listed on the SDS. PPE

Hazards to watch on window glass replacement

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

Step 1, 2, 3Glass handling and breakageGlass panes break while being moved or fitted, causing deep cuts, or heavy panels fall and crush.
Step 2Eye injuriesFlying chips, dust, chemicals or sparks get into the eye and cause damage or blindness.
Step 4Hazardous chemicalsGlues, sealants, solvents, acids, cleaners and cement burn skin and eyes or cause breathing problems and poisoning.
Step 4Falling from a ladderThe ladder slips or tips, or the worker overreaches, and they fall onto a hard surface.
Step 2Cuts from sharp edgesSheet metal, glass, blades, cable tray and offcuts cut hands and arms.
Step 1Public entering the work areaMembers of the public, including children, walk into the site and are hit by plant or falling objects, or fall into holes.
Almost certainLikelyPossibleUnlikelyRareHow bad it could be: First aid only to FatalityBA
Highest risk on window glass replacement: High before controls (B), down to Medium after controls (A), on the United States 5 by 5 risk matrix (possible and serious injury 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 window glass replacement?

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

Usually Cut-resistant gloves, Safety glasses (ANSI Z87.1), Safety-toe boots (ASTM F2413), High-visibility safety apparel, ANSI/ISEA 107 Class 2 or 3 (Type R near roadways), Safety goggles (ANSI Z87.1), Face shield (ANSI Z87.1), Work gloves, Hard hat (ANSI Z89.1), Chemical-resistant gloves, Half-face respirator (P100 cartridges), Coveralls. The site rules may add more, so check with the general contractor.
