18 Jun Plumbing Safety

Plumbing Safety

Plumbers install, repair, and maintain piping, fixtures, and systems used for water supply, drainage, waste disposal, heating, and other building services. Plumbing work involves much more than working with pipes. Plumbers may handle hazardous materials, use power and hand tools, perform hot work, lift heavy materials, work in confined or wet areas, and encounter electrical, biological, and atmospheric hazards.

Understanding the hazards of each job and using the proper controls, equipment, and personal protective equipment (PPE) are essential to working safely.

Hazardous Materials and Chemicals

Before beginning work, determine whether hazardous materials may be present. Older buildings and renovation projects may contain asbestos, lead-based paint, mold, or other hazardous substances.

• Do not disturb suspected asbestos-containing material unless properly trained, authorized, and protected to perform the work.
• Evaluate painted or coated surfaces for potential lead hazards before cutting, grinding, sanding, burning, or otherwise disturbing them.
• Report suspected mold, asbestos, lead, or other hazardous materials to your supervisor.
• Follow established procedures before disturbing contaminated materials.
• Never assume an unknown material is harmless.

Plumbers may also use soldering products, fluxes, adhesives, primers, sealants, solvents, cleaners, and other chemicals. Review the Safety Data Sheet (SDS) before use and follow all label instructions, ventilation requirements, and PPE precautions.

Sewage and Biological Hazards

Plumbing work involving sanitary sewer systems, drains, toilets, or wastewater can expose workers to harmful microorganisms and contaminated materials.

When exposure is possible:

• Wear appropriate gloves and protective clothing.
• Protect cuts and broken skin from contamination.
• Avoid touching your face, eyes, nose, or mouth with contaminated gloves or hands.
• Wash thoroughly with soap and water before eating, drinking, or leaving the work area.
• Clean and disinfect contaminated tools and equipment as appropriate.
• Remove contaminated clothing carefully to prevent spreading contamination.
• Never eat, drink, or smoke in areas contaminated with sewage or wastewater.

Confined Spaces and Hazardous Atmospheres

Manholes, tanks, pits, crawlspaces, sewers, and similar areas may meet the definition of a confined space and may contain dangerous atmospheres.

Hazards can include:

• Oxygen deficiency or enrichment.
• Hydrogen sulfide.
• Methane and other flammable gases.
• Toxic gases or vapors.
• Engulfment.
• Restricted entry or exit.

Never enter a confined space until it has been evaluated and you are authorized to enter. Where required, atmospheric testing, ventilation, entry permits, attendants, communication equipment, and rescue procedures must be established before entry.

Never rely on smell to determine whether an atmosphere is safe.

Electrical Safety

Water, damp locations, metal piping, and electrical equipment can create a serious shock or electrocution hazard.

• Inspect electrical tools, cords, and plugs before use.
• Use equipment suitable for the environment.
• Use required ground-fault circuit interrupter (GFCI) protection.
• Keep electrical connections away from standing water.
• Remove damaged electrical equipment from service.
• Never use makeshift electrical connections or damaged extension cords.
• Identify nearby electrical wiring before drilling, cutting, or opening walls, ceilings, or floors.

If you experience tingling or receive even a minor shock while touching piping, equipment, or another conductive surface, stop work immediately and report the condition. Do not continue until the source has been identified and the hazard corrected.

Hot Water, Steam, and Pressure

Piping systems may contain hot water, steam, compressed gases, or other materials under pressure. Never assume a system is depressurized simply because equipment has been shut down.

Before opening or disconnecting piping:

• Identify the contents of the system.
• Shut down and isolate the appropriate energy sources.
• Lockout/tagout when required.
• Relieve stored pressure.
• Drain the system when appropriate.
• Allow hot components to cool.
• Verify that isolation is effective before beginning work.

Position yourself so that unexpected releases are directed away from your face and body.

Tools and Equipment

Plumbers routinely use pipe cutters, threaders, saws, drills, grinders, torches, presses, and numerous hand tools.

• Use the correct tool for the task.
• Inspect tools before use.
• Keep cutting tools properly maintained.
• Ensure machine guards and safety devices are installed and functional.
• Secure materials before drilling, cutting, grinding, or threading.
• Keep hands clear of blades, rotating components, and pinch points.
• Never remove or bypass guards or safety devices.
• Disconnect or isolate energy before clearing jams, making adjustments, or servicing equipment.
• Wear appropriate eye and face protection when exposed to flying particles, sparks, or splashes.

Hot Work and Fire Prevention

Soldering, brazing, welding, and torch cutting introduce fire, burn, and fume hazards.

Before performing hot work:

• Inspect the surrounding area for combustible materials.
• Follow applicable hot-work permit requirements.
• Provide appropriate fire-extinguishing equipment.
• Protect nearby workers and combustible surfaces from sparks and heat.
• Provide adequate ventilation.
• Inspect hoses, regulators, torches, and cylinders before use.
• Secure compressed-gas cylinders upright and protect them from damage.
• Wear appropriate eye, face, hand, and body protection.

Never perform hot work where flammable gases or vapors may be present until the area has been evaluated and determined safe.

Slips, Trips, and Falls

Plumbing work frequently takes place in wet, congested, or unfinished areas.

• Clean up water and spills promptly.
• Keep hoses, cords, tools, pipe, and materials out of walkways.
• Maintain adequate lighting.
• Wear sturdy footwear with slip-resistant soles.
• Use ladders and scaffolds properly when working at elevation.
• Never use buckets, boxes, piping, or other makeshift devices as work platforms.
• Maintain three points of contact when climbing ladders.

Ergonomics and Material Handling

Pipe, fixtures, water heaters, equipment, and plumbing supplies can be heavy, bulky, and difficult to handle. Plumbing work also frequently requires kneeling, reaching, twisting, and working in confined positions.

Before lifting:

• Determine the weight and stability of the load.
• Plan the lift and travel path.
• Use mechanical lifting equipment whenever practical.
• Get assistance with heavy or awkward loads.
• Keep the load close to your body.
• Avoid twisting while lifting or carrying.
• Reposition yourself rather than overreaching.

Change positions periodically and rotate tasks when practical to reduce prolonged awkward postures and repetitive motion.

Personal Protective Equipment

Required PPE depends on the task and hazards and may include:

• Safety glasses or goggles.
• Face shields.
• Work gloves appropriate for the hazard.
• Chemical-resistant gloves and clothing.
• Hard hats.
• Safety footwear.
• Hearing protection.
• Respiratory protection.
• High-visibility clothing.
• Fall-protection equipment.

Respirators may only be used in accordance with the company Respiratory Protection Program when respiratory protection is required.

Remember

Plumbing work can expose employees to chemicals, sewage, electricity, hazardous atmospheres, pressure, hot surfaces, power tools, fire hazards, falls, and ergonomic injuries. Evaluate the job before starting, use the proper PPE and equipment, and stop work when unexpected hazards are discovered.

Never open, cut, drill, disconnect, or enter something until you know what hazards may be on the other side.
