# Job Hazard Analysis: Fixture installation URL: https://hardhatbinder.com/en/jha/plumbing/fixture-installation Last updated: 2026-10-23 Setting and connecting toilets, lavatory sinks, kitchen sinks, and faucets in new or remodeled residential or light commercial buildings. Includes carrying fixtures in, cutting and joining PVC, PEX, and copper connections (including soldering with a propane or MAPP torch), drilling for anchors, leak testing, and cleanup. Work is done in tight bathrooms and under cabinets, often with other trades nearby. > 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 ### 1. Unload and carry fixtures (toilets, sinks, vanity tops) from the truck to the work area. - **Back strain from lifting 60–100 lb toilets, cast iron sinks, or stone vanity tops, especially on stairs.** (Medium): Use a hand truck or appliance dolly to move boxed fixtures; leave them in the box until you reach the room.; Use two people for anything over 50 lb and for all carries up or down stairs.; Walk the path first and clear cords, scraps, and tools out of the way.; Lift with your legs, keep the load close, and do not twist while carrying. - **Hand cuts and crushed toes from dropped or broken porcelain.** (Medium): Check boxes for damage before lifting; handle cracked fixtures as broken glass.; Wear cut-resistant gloves and safety-toe boots while carrying. ### 2. Shut off water, drain lines, and prepare stub-outs and the closet flange. - **Hot water scald or flooding from a live line that was not shut off.** (Medium): Close the fixture stops or main valve, then open the lowest faucet to drain and confirm no pressure before cutting.; Tag the closed main valve so no one turns it back on.; Keep a bucket and towels under the line when you open it. - **Sewer gas and bacteria from an open drain or old wax ring.** (Low): Plug the open closet flange with a rag or test cap until the toilet is set.; Wear nitrile gloves and wash your hands before eating or drinking. ### 3. Cut and join supply and drain connections: PVC with primer and cement, PEX with crimp tool, copper with a torch. - **Fire from torch flame igniting wood framing, insulation, or paper behind the wall.** (High): Use press fittings, PEX, or push-fit connections instead of soldering when the job allows.; Place a heat shield or flame-resistant cloth behind every joint you solder.; Keep a charged ABC fire extinguisher within reach and wet down nearby wood if needed.; Do a fire watch for at least 30 minutes after the last joint; feel the wall and check for smoke. - **Burns from hot copper, solder, and the torch tip.** (Medium): Let joints cool or wipe with a wet rag before touching; shut off the torch when you set it down.; Wear leather gloves and safety glasses while soldering. - **Fumes and skin or eye irritation from PVC primer, cement, and flux.** (Medium): Open a window or run a fan to move air out of small bathrooms; cap cans right after use.; Read the SDS and keep primer and cement away from the torch.; Wear nitrile gloves and safety glasses when applying primer and cement. - **Cuts from tubing cutters, hacksaws, and utility knives.** (Low): Use a ratchet PVC cutter or tubing cutter instead of a knife; clamp pipe before sawing.; Deburr cut ends and cut away from your body. ### 4. Drill for anchors and carriers in tile, concrete, or drywall for wall-hung sinks and supports. - **Silica dust from drilling tile, stone, or concrete.** (Medium): Use a drill with a dust shroud connected to a HEPA vacuum, or drill wet with a spray bottle.; Keep other workers out of the room while drilling.; Clean dust with a HEPA vacuum; never dry sweep or blow it with air. - **Electric shock from drilling into hidden wiring or using a damaged cord in a wet area.** (High): Use cordless tools when possible; plug corded tools into a GFCI.; Check the wall with a stud and wire finder and look for outlets or switches nearby before drilling.; Inspect cords and tools before use; tag out any with cut insulation or missing ground pins. - **Flying chips and noise from the hammer drill.** (Low): Wear safety glasses and earplugs while drilling. ### 5. Set the toilet and install sinks and faucets, working on knees and under cabinets. - **Back and knee strain from lowering the toilet onto the wax ring and working in cramped spaces.** (Medium): Set the tank after the bowl is placed to cut the weight; get a helper for one-piece toilets.; Use kneepads and a cabinet creeper or foam pad when lying under sinks; take short stretch breaks. - **Pinched fingers and cuts from porcelain cracking when bolts are overtightened.** (Low): Tighten closet and tank bolts by hand, then snug a little at a time, alternating sides.; Wear cut-resistant gloves when handling broken porcelain. - **Debris falling in eyes when working face-up under a sink.** (Low): Wear safety glasses under cabinets and use a headlamp instead of leaning in close. ### 6. Turn the water back on, test for leaks, and check drains. - **Water spraying from a loose fitting, making floors slippery near power tools and outlets.** (Medium): Unplug and move power tools and cords out of the room before opening the valve.; Open the valve slowly while one person watches the connections.; Mop up water right away and put out a wet floor sign. ### 7. Clean up packaging, scrap pipe, and broken porcelain, and remove tools. - **Trips over cardboard, scrap pipe, and cords left in hallways.** (Low): Break down boxes and haul scrap to the dumpster as you go, not just at the end of the day.; Coil cords and keep walkways clear. - **Cuts from broken porcelain and sharp pipe ends in trash.** (Low): Put broken porcelain in a box or bucket, not loose in a trash bag.; Wear cut-resistant gloves during cleanup. ## Required PPE - ANSI Z87.1 safety glasses — At all times, especially when soldering, drilling, cutting, and working under sinks. - Cut-resistant gloves — When carrying fixtures, handling porcelain, and cleaning up. - Nitrile gloves — When using PVC primer, cement, flux, or touching drains. - Leather gloves — When soldering copper with a torch. - Safety-toe work boots — At all times on site. - Kneepads — When setting toilets and working on the floor. - Earplugs or earmuffs — When using a hammer drill or saw. - N95 or half-face respirator — Only if drilling tile or concrete without a working dust shroud and HEPA vacuum or water. ## Training - Hazard communication: reading labels and SDS for PVC primer, cement, flux, and solder. - Safe torch use, hot work fire prevention, fire watch, and how to use an ABC fire extinguisher. - Power tool inspection and GFCI use, given by a competent person. - Silica dust controls for drilling tile and concrete. - Safe lifting and team carrying of heavy fixtures. ## Emergency If a fire starts from the torch: shout to warn everyone, use the ABC extinguisher only if the fire is small, otherwise get everyone out and call 911 with the site address. For a serious burn or cut: stop work, call 911, give the address, cool burns with clean water, and press hard on bleeding with a clean cloth until help arrives. ## Official sources - [29 CFR 1926.20](https://www.ecfr.gov/current/title-29/section-1926.20) — General safety and health provisions - [29 CFR 1926.21](https://www.ecfr.gov/current/title-29/section-1926.21) — Safety training and education - [29 CFR 1926.25](https://www.ecfr.gov/current/title-29/section-1926.25) — Housekeeping - [29 CFR 1926.59](https://www.ecfr.gov/current/title-29/section-1926.59) — Hazard communication - [29 CFR 1926.300](https://www.ecfr.gov/current/title-29/section-1926.300) — Hand and power tools — general requirements - [29 CFR 1926.352](https://www.ecfr.gov/current/title-29/section-1926.352) — Fire prevention (welding and cutting) - [29 CFR 1926.404](https://www.ecfr.gov/current/title-29/section-1926.404) — Wiring design and protection - [29 CFR 1926.1153](https://www.ecfr.gov/current/title-29/section-1926.1153) — Respirable crystalline silica --- Source: HardHat Binder, operated by Leadspire LLC.
