Job Hazard Analysis: Taping and finishing

Interior taping, bedding, and finishing of hung drywall: mixing joint compound, taping joints and corners, applying finish coats on walls and ceilings, sanding, and cleanup. Work is done from the floor, 6-ft fiberglass stepladders, baker scaffolds, or drywall stilts, using hand tools, automatic taping tools, and corded drills with mixing paddles.

A general example for this task. Your JHA should reflect your crew, equipment and site — review it with a competent person before work starts.

Steps, hazards and controls

Step	Hazard	Risk	Controls
1. Stage materials and set up the work area	Back strain from lifting 50-lb boxes and 5-gallon buckets of joint compound	Medium	Have the supplier stock compound on each floor, close to where you will use it. Use a hand truck or dolly to move buckets and boxes. Lift with your legs, keep the load close, and get help for anything awkward.
	Trips over cords, hoses, drywall scraps, and buckets	Medium	Sweep the floor and haul out drywall scraps before starting. Run extension cords along walls or overhead, not across walkways. Keep buckets and tools in one staging spot, out of door openings and stairs.
	Falls through floor openings, stairwells, or unguarded window openings	High	Walk the area first and confirm all floor holes are covered and marked, and stair and window openings have guardrails. Report any missing cover or guardrail to the foreman and do not work near it until fixed.
2. Mix joint compound with a drill and paddle	Drill kicks back and twists your wrist when the paddle binds	Medium	Use a low-speed, high-torque mixing drill with a side handle. Set the bucket on the floor and hold it with your feet; start slow with the paddle fully in the mud. Stop the drill before pulling the paddle out of the bucket.
	Electric shock from damaged cords or wet conditions	Medium	Plug into a GFCI outlet or portable GFCI. Check the drill and cord for cuts and missing ground pins before use; tag out and remove damaged ones. Keep plugs and connections out of water and mixing slop.
	Dust and splashes in eyes when mixing dry setting compound (hot mud)	Medium	Use premixed compound when possible to avoid dry powder. Pour powder slowly into water, low in the bucket, and read the SDS before using a new product. Wear safety glasses; add a dust mask when mixing dry powder.
3. Set up stepladders, baker scaffolds, or stilts	Falls from a baker scaffold that rolls, tips, or has a missing plank	High	Inspect the scaffold before each shift: frames, cross braces, pins, casters, and a fully planked deck. Lock all casters before climbing on; never ride or move the scaffold with anyone on it. Install guardrails when the platform height requires them, and never stand on buckets or toe boards to reach higher.
	Falls from a 6-ft fiberglass stepladder	Medium	Use a ladder tall enough so you never stand on the top cap or top step. Open it fully with spreaders locked, on a flat floor cleared of scraps. Keep your belt buckle between the rails and move the ladder instead of leaning out.
	Falls while walking on drywall stilts	High	Use stilts only in rooms with clean, level floors, away from stairs, floor openings, and window openings. Inspect straps, springs, and wing nuts before each use; adjust to your height per the maker's instructions. Only workers trained and approved by the foreman may use stilts.
4. Tape and bed joints, corners, and corner bead	Cuts from utility knives and sharp metal corner bead	Medium	Use self-retracting utility knives and replace dull blades. Cut away from your body and hands; never leave an open knife on a scaffold or bucket. Wear cut-resistant gloves when handling or cutting metal bead.
4. Tape and bed joints, corners, and corner bead	Wrist, shoulder, and hand strain from repeated knife and taping-tool work	Low	Use automatic tapers, banjos, and corner flushers to cut down on hand motions. Rotate between tasks and take short stretch breaks.
5. Apply fill and finish coats on walls and ceilings	Compound dripping into eyes during overhead ceiling work	Medium	Use pole-mounted finishing boxes and flat boxes so your face is not directly under the work. Wear safety glasses at all times; use goggles for overhead work. Flush eyes with clean water for 15 minutes if compound gets in them.
	Neck and shoulder strain from reaching overhead	Low	Work from a baker scaffold or stilts at a height that keeps the ceiling near head level. Rotate ceiling work among crew members.
	Slips on wet compound on the floor	Medium	Lay down drop cloths or rosin paper under the work. Scrape up drips right away, especially around ladders, scaffolds, and stilt areas.
6. Sand finished joints	Breathing joint compound dust, which can contain crystalline silica, mica, or talc	High	Use low-dust compound and check the SDS for crystalline silica before starting. Wet sand with a sponge, or use a pole or power sander hooked to a HEPA vacuum. Close off the room with plastic, keep others out, and do not dry sweep or blow dust with compressed air. Wear at least an N95 respirator when dry sanding; use a fit-tested respirator if required by the respiratory program.
6. Sand finished joints	Dust in eyes from sanding overhead	Medium	Use a vacuum sander to capture dust at the source. Wear dust-tight goggles when sanding ceilings.
7. Clean tools and the work area	Dust exposure when sweeping and emptying vacuums	Medium	Clean up with a HEPA vacuum or wet methods, not dry sweeping. Bag vacuum contents slowly and keep your respirator on while emptying.
7. Clean tools and the work area	Slips and trips from wash water, buckets, and scraps	Low	Wash tools in a designated spot and dump wash water where directed, not in sinks or floor drains. Haul trash and scraps to the dumpster and stack leftover buckets out of walkways.

Required PPE

Safety glasses — ANSI Z87.1, worn at all times.
Dust-tight goggles — For overhead finishing and sanding, and mixing dry powder.
N95 or better respirator — When dry sanding, mixing dry compound, and emptying vacuums; follow the company respiratory program.
Work gloves — Cut-resistant gloves for metal bead; nitrile gloves to protect skin from wet compound.
Hard hat — When required by the site or when other trades work overhead.
Slip-resistant work boots — At all times on site.

Training

Ladder safety training: picking the right ladder, inspection, setup, and safe climbing.
Scaffold user training on baker scaffolds by a qualified person: inspection, locking casters, planking, and guardrails.
Stilt training and foreman approval before using drywall stilts.
Hazard communication training on joint compound SDSs, including silica and dust hazards.
Respirator training, medical clearance, and fit testing if tight-fitting respirators are required.
Safe use of power tools and GFCI protection for mixing drills and sanders.

Emergency

If someone falls from a scaffold, ladder, or stilts: stop work, do not move the injured worker unless they are in danger, call 911 and give the site address, send someone to meet the ambulance, give first aid, and notify the foreman.
