Job Hazard Analysis: Trim and finish carpentry

Interior finish work on a residential or light commercial job: cutting and installing baseboard, door and window casing, crown molding, interior doors, and shelving. Uses a sliding compound miter saw, 15/16-gauge finish nailer, 18-gauge brad nailer, portable air compressor, coping saw, oscillating tool, random orbit sander, and 6-ft fiberglass stepladder. Includes caulking, wood filler, construction adhesive, and cleanup.

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 trim and set up the cutting station	Back strain and hitting people or walls while carrying long trim boards	Medium	Have the material dropped as close to the work room as possible. Carry boards over 12 ft with two people, one at each end, and call out at corners and doorways. Lift with your legs and keep the load close to your body.
	Shock from damaged extension cords or ungrounded outlets	Medium	Plug the saw and compressor into a GFCI outlet or a portable GFCI. Inspect cords before use; tag out and remove any cord with cuts, missing ground prong, or taped splices.
	Tripping over cords, air hoses, and trim stacks	Medium	Set the saw station out of walkways and stack trim flat against a wall. Run cords and hoses along walls, not across doorways or stairs.
2. Measure and cut trim on the miter saw	Hand contact with the saw blade, causing deep cuts or amputation	High	Keep the blade guard working; never pin it open or remove it. Mount the saw on a stand with extension supports so long pieces stay flat and you never hold the cut-off. Keep hands at least 6 in from the blade; use a clamp for short pieces. Let the blade stop fully before lifting the saw head or reaching for scraps. Do not wear gloves or loose sleeves while running the saw.
	Flying chips and small offcuts hitting the eyes	Medium	Use a sharp finish blade and cut crown in a crown jig or nested against the fence so it cannot roll. Keep other workers out of the area beside and behind the saw. Wear safety glasses.
	Loud noise from the miter saw	Medium	Set the saw station away from where others are working when possible. Wear earplugs or earmuffs while cutting.
	Fine dust from cutting MDF and hardwood	Medium	Connect the saw to a shop vacuum or dust extractor. Cut outside or near an open window with a fan blowing dust away from you. Wear an N95 dust mask when cutting a lot of MDF.
3. Cope, scribe, and notch trim with hand and oscillating tools	Cuts from utility knives, chisels, coping saws, and the oscillating tool	Medium	Clamp the piece to a sawhorse or bench instead of holding it in your hand. Cut away from your body and keep your free hand behind the blade. Use a retractable utility knife and replace dull blades. Wear cut-resistant gloves for hand tool work.
4. Install base, casing, doors, and shelving with the finish nailer	Nail gun puncture injuries to hands or body, including nails blowing out through thin trim	High	Use nailers with a sequential (single-shot) trigger. Keep your free hand at least 12 in from the nailing point and never hold trim right behind the nail. Pick a nail length that fits the trim and backing, and angle the gun away from your body. Disconnect the air hose before clearing jams, loading, or handing the gun to someone. Wear safety glasses.
	Hitting hidden wires or plumbing when nailing or screwing into walls	Medium	Use a stud finder with wire detection before nailing near outlets, switches, and fixtures. Keep nails out of the area directly above and below outlets and switches.
	Knee and back strain from kneeling to install baseboard	Low	Pre-cut and stage pieces at waist height to reduce time on your knees. Take short stretch breaks and rotate tasks. Wear knee pads.
	Back strain and pinched fingers when hanging prehung doors	Medium	Use two people to set solid-core doors in the opening. Keep fingers out of the hinge side and jamb while setting and shimming.
5. Install crown molding and high trim from a stepladder	Falling from the stepladder while reaching or nailing overhead	High	Use a rolling work platform or baker scaffold with locked wheels and guardrails for long runs of crown. Use a 6-ft fiberglass stepladder rated for your weight plus tools; open it fully and lock the spreaders. Never stand on the top cap or the step below it, and keep your belt buckle between the rails. Move the ladder instead of leaning out; set it on a clean, level floor. Inspect the ladder before use and tag out any with cracked rails or loose steps.
	Long crown pieces swinging and knocking the installer off balance	Medium	Use two workers on two ladders for pieces over 8 ft. Install blocking or a cleat at the wall to support the crown while nailing.
	Air hose snagging the ladder or someone walking below	Low	Route the hose behind the ladder and keep others out of the area under overhead work.
6. Fill nail holes, caulk, glue, and sand	Breathing sanding dust from MDF, primed trim, and wood filler	Medium	Use a random orbit sander connected to a shop vacuum. Ventilate the room with open windows and a box fan blowing out. Wear an N95 dust mask and safety glasses while sanding.
6. Fill nail holes, caulk, glue, and sand	Skin and breathing exposure to construction adhesive, solvent-based caulk, and stain	Medium	Choose water-based caulk, filler, and adhesive when the job allows. Read the label and Safety Data Sheet before use and keep containers closed. Keep solvent-based products away from sparks and flames, and ventilate the room. Wear nitrile gloves when handling adhesives and stain.
7. Clean up and shut down tools	Punctures and trips from offcuts with nails, sawdust, and loose debris	Medium	Pick up scraps throughout the day and put them in a bin or bag, not on the floor. Vacuum sawdust instead of dry sweeping or using compressed air. Wear work gloves when handling scrap.
	Fire from stain or oil-soaked rags heating up on their own	Medium	Lay oily rags flat outside to dry or put them in a closed metal can filled with water. Never leave wadded rags in the building overnight.
	Stored air pressure and unexpected tool start-up	Low	Unplug the saw, disconnect nailers, and bleed the compressor tank at the end of the day. Coil cords and hoses and store tools out of walkways.

Required PPE

Safety glasses — ANSI Z87.1, worn at all times while cutting, nailing, and sanding.
Hearing protection — Earplugs or earmuffs while running the miter saw, compressor, or sander.
N95 dust mask — When cutting or sanding MDF or doing heavy sanding indoors.
Gloves — Cut-resistant gloves for knives and scrap; nitrile for adhesives and stain. No gloves on the miter saw.
Knee pads — When installing baseboard or working on the floor.
Work boots — Closed-toe, slip-resistant soles; safety toe if handling doors and heavy stock.
Hard hat — When other trades work overhead or when the general contractor requires it.

Training

Miter saw operation and guarding, shown by a competent person before first use.
Pneumatic nail gun safety, including sequential trigger use and clearing jams.
Ladder safety training: inspection, setup, and safe climbing.
Rolling platform or baker scaffold use, if used on the job.
Hazard communication: reading labels and SDS for adhesives, caulk, filler, and stain.

Emergency

For a serious saw cut or nail gun injury: stop work and shut off or unplug the tool. Call 911 and give the full site address. Press hard on the wound with a clean cloth. Do not pull out an embedded nail. Wrap any severed part in clean gauze, put it in a sealed bag on ice, and send it with the worker. Send someone to meet the ambulance.
