# Job Hazard Analysis: Drain line installation URL: https://hardhatbinder.com/en/jha/plumbing/drain-line-installation Last updated: 2026-10-23 Installing interior PVC or ABS drain, waste, and vent (DWV) piping in new or remodeled buildings. This covers staging pipe, drilling through wood framing, cutting and solvent-welding pipe, hanging pipe overhead from ladders, tying into an existing drain, testing, and cleanup. Underground trenching and confined space work are not covered; do a separate JHA for those. > 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 stage pipe, fittings, primer, and cement - **Back strain from lifting bundles of 10-ft and 20-ft pipe** (Medium): Use a pipe cart or dolly to move bundles.; Two people carry any pipe longer than 10 ft, one at each end.; Lift with your legs and keep the load close to your body. - **Pipe rolling off the stack and crushing feet or tripping workers** (Low): Stack pipe on a flat surface and block both sides with 2x4 chocks.; Keep stacks out of walkways and doorways.; Wear safety-toe boots. - **Fire from primer and cement stored near heat or sparks** (Medium): Store cans closed, in the shade, away from heaters, torches, and grinders.; Keep a 10-lb ABC fire extinguisher at the work area.; Read the SDS for the primer and cement before use. ### 2. Lay out the run and drill or notch framing with a right-angle drill - **Right-angle drill kickback when a hole saw binds, causing broken wrists or arms** (High): Use a drill with a clutch or anti-kickback feature.; Always use the side handle and brace it against a stud, never your body.; Keep hole saws and self-feed bits sharp and check for nails before drilling. - **Drilling into hidden live wiring, water, or gas lines in walls and floors** (High): Check plans and look inside the wall or ceiling cavity before drilling.; In remodels, have the electrician turn off and lock out circuits in the work area.; Use a cordless drill or a GFCI-protected cord, and check cords for damage. - **Wood chips and dust in eyes** (Medium): Wear safety glasses at all times; add a face shield when drilling overhead. ### 3. Cut and deburr pipe - **Cuts from saws, ratchet cutters, and sharp burrs** (Medium): Use a ratchet pipe cutter or wheel cutter instead of a hand saw when the pipe size allows.; Clamp pipe in a pipe vise or stand; never hold it on your leg.; Wear cut-resistant gloves when deburring. - **Power saw contact and flying chips when using a miter saw or reciprocating saw** (Medium): Keep blade guards in place and working.; Keep hands at least 6 in from the blade and unplug the saw before changing blades.; Wear safety glasses and hearing protection. ### 4. Prime and solvent-weld joints - **Breathing solvent vapors in closed rooms, crawl spaces, or bathrooms** (Medium): Use low-VOC cement where the code allows.; Open windows and run a fan to blow vapors outside.; Close cans between joints and take fresh-air breaks if you feel dizzy or get a headache. - **Primer and cement splashing into eyes or soaking skin** (Medium): Keep an eyewash bottle at the work area.; Wear safety glasses and nitrile gloves. - **Flash fire from vapors near pilot lights, heaters, or sparks** (High): Turn off pilot lights and heaters in the room before gluing.; No smoking, torches, or grinding within 25 ft while gluing.; Keep the fire extinguisher within reach. ### 5. Hang and support pipe overhead from a ladder - **Falls from a 6-ft or 8-ft fiberglass stepladder** (High): Use a rolling scaffold or platform ladder for long overhead runs.; Open the stepladder fully, lock the spreaders, and set it on level ground.; Never stand on the top step or top cap; keep three points of contact.; Inspect the ladder before use and tag out any damaged ladder. - **Pipe or hangers falling on workers below** (Medium): Have a helper hand up pipe and keep others out from under the work.; Install hangers loosely first, then tighten after the pipe is set.; Wear a hard hat. - **Neck and shoulder strain from overhead work** (Low): Pre-assemble sections on the floor when possible.; Rotate overhead tasks and take short breaks. ### 6. Cut into and tie in to the existing drain or cast iron stack - **Contact with sewage and sewer gas from the open drain** (Medium): Tell occupants not to use fixtures and tape off toilets and sinks upstream.; Plug the open pipe with a test plug when not working on it and ventilate the area.; Wear nitrile gloves and safety glasses; wash hands before eating. - **Heavy cast iron section dropping when cut with a snap cutter or reciprocating saw** (High): Install riser clamps above and below the cut before cutting.; Have a second worker support the section and keep feet clear.; Wear safety-toe boots and a face shield over safety glasses. - **Noise from cutting cast iron** (Medium): Use a snap cutter instead of a saw when possible.; Wear earplugs or earmuffs while cutting. ### 7. Test the drain system with water or air - **Test plug blowing out under pressure and striking a worker** (High): Use a water test instead of an air test on plastic pipe when the inspector allows.; Use a regulator and gauge and never go over the test pressure required by code.; Never stand in front of a plug while filling or draining; release pressure before removing plugs. - **Water spills causing slips and soaking electrical outlets** (Medium): Drain test water into a floor drain or bucket with a hose, not onto the floor.; Keep cords and tools off wet floors and use GFCI protection. ### 8. Clean up the work area - **Trips and cuts from pipe scraps, shavings, and cords** (Low): Pick up scraps and shavings as you go and at the end of each day.; Coil cords and put tools away. - **Fire from rags and empty cans with primer and cement** (Medium): Put used rags and empty cans in a closed metal container and remove them from the building.; Make sure all cans are closed tight before storing. ## Required PPE - Safety glasses — ANSI Z87.1, at all times. Add a face shield when drilling overhead or cutting cast iron. - Hard hat — When working under overhead pipe work or where materials can fall. - Safety-toe boots — At all times on site, especially when handling cast iron. - Nitrile gloves — When using primer and cement and when opening existing drains. - Cut-resistant work gloves — When cutting, deburring, and handling pipe. - Hearing protection — Earplugs or earmuffs when using saws or cutting cast iron. ## Training - Ladder safety training by a competent person before using ladders. - Hazard communication training on the SDS for primer, cement, and cleaners. - Hands-on training on the right-angle drill, saws, and cast iron snap cutter, including kickback hazards. - Safe drain testing procedures, including plug use and pressure limits. - Fire extinguisher use. ## Emergency If a worker is hurt by a fall, drill kickback, or electric shock: stop work. For shock, turn off the power before touching the person. Call 911 and give the full site address. Do not move a person who fell unless they are in danger. Give first aid or CPR until help arrives. For primer in the eyes, flush with clean water for 15 minutes. ## Official sources - [29 CFR 1926.1053](https://www.ecfr.gov/current/title-29/section-1926.1053) — Ladders - [29 CFR 1926.300](https://www.ecfr.gov/current/title-29/section-1926.300) — Hand and power tools — general requirements - [29 CFR 1926.152](https://www.ecfr.gov/current/title-29/section-1926.152) — Flammable liquids - [29 CFR 1910.1200](https://www.ecfr.gov/current/title-29/section-1910.1200) — Hazard communication (GHS) - [29 CFR 1926.416](https://www.ecfr.gov/current/title-29/section-1926.416) — Electrical — general requirements - [29 CFR 1926.102](https://www.ecfr.gov/current/title-29/section-1926.102) — Eye and face protection - [29 CFR 1926.25](https://www.ecfr.gov/current/title-29/section-1926.25) — Housekeeping - [29 CFR 1926.21](https://www.ecfr.gov/current/title-29/section-1926.21) — Safety training and education --- Source: HardHat Binder, operated by Leadspire LLC.
