Portable Hand Washing Stations for Construction Sites and Temporary Work Areas

Portable hand washing stations provide running water at construction sites and temporary work areas without requiring permanent plumbing. Self-contained models use freshwater and wastewater tanks, along with an electric pump to supply the faucet.

For contractors and site supervisors, choosing suitable equipment means considering OSHA sanitation requirements, worker access, electrical service, and ongoing maintenance.

What Handwashing Requirements Apply to Construction Sites?

The Occupational Safety and Health Administration (OSHA) establishes sanitation requirements for construction workplaces under 29 CFR 1926.51.

Under the federal standard, lavatories generally must be available to employees and provide:

• Hot and cold running water, or tepid running water.
• Hand soap or similar cleansing agents.
• Individual hand towels or another permitted hand-drying method.

Exceptions apply to qualifying mobile crews and normally unattended work locations when employees have transportation readily available to nearby washing facilities that meet the standard.

OSHA requires adequate washing facilities near the worksite for employees applying paints or coatings, or performing other operations involving potentially harmful contaminants. These facilities must allow workers to remove the substances involved. General handwashing stations may not satisfy specialized hygiene or decontamination requirements.

Employers should assess the work being performed and confirm applicable federal or state-plan OSHA requirements before selecting equipment. Different sanitation regulations may apply to temporary workplaces outside the construction industry.

Where Should Hand Washing Stations Be Placed on a Job Site?

Handwashing facilities should be accessible to workers without interfering with construction activities.

Depending on the site layout, suitable locations may include areas near portable restrooms, designated break spaces, or frequently used work zones.

When selecting a location, consider:

• Accessibility: Choose a location workers can reach without unnecessary travel or obstacles, even as construction activities progress.
• Ground conditions: Place the cabinet on a stable, level surface.
• Worksite traffic: Keep the station clear of moving equipment, vehicle routes, and material-handling areas.

Which Portable Hand Washing Stations Are Suitable for Job Sites?

The appropriate model depends on water-temperature requirements, available electrical service, and the type of work being performed.

Our heavy-duty resin-cabinet stations are suitable for specified indoor and outdoor applications. Options for construction and temporary workspaces include:

• Hot Water Portable Hand Washing Station – Model 35-0092: Provides hot and cold running water through a single stainless steel basin. It includes a 2.5-gallon electric water heater.
• Full-Size Portable Hand Sink – Model 35-0105: Offers hot and cold water with a larger 19½″ × 11¾″ basin for applications requiring additional handwashing space.
• Cold Water Portable Hand Wash Station – Model 35-0091: Supplies room-temperature water without an onboard heater. This model should only be considered where its delivered water temperature and the overall handwashing arrangement meet applicable workplace sanitation requirements.

However, the presence of a heater does not automatically establish OSHA compliance. The selected equipment must provide the required water conditions and meet other applicable sanitation requirements during operation.

What Electrical Power Is Needed at a Construction Site?

Our resin-cabinet Models 35-0091, 35-0092, and 35-0105 use 110V/15A electrical service. The pump requires power to deliver water to the faucet, while heated configurations also use electricity for their water heaters.

Before installing a station, confirm that the worksite has a compatible electrical source.

Temporary power arrangements should account for:

• A circuit that meets the unit's electrical requirements.
• Appropriate ground-fault protection under applicable construction-site electrical rules.
• Electrical connections protected from water exposure and physical damage.
• Power cords routed away from vehicle traffic and pedestrian hazards.

 Follow the manufacturer's instructions and applicable construction-site electrical standards.

How Should Freshwater and Wastewater Be Managed?

Portable handwashing stations require an adequate freshwater supply and a way to collect used water.

Our models feature 5-gallon freshwater tanks and separate wastewater containers. Servicing frequency depends on the number of workers, handwashing activity, and actual consumption.

To maintain access throughout the workday:

• Keep potable water available for refilling.
• Monitor tank levels and service the station before either container limits its use.
• Dispose of wastewater at an approved sanitary disposal location.
• Assign responsibility for replenishing water and checking supplies.

Larger crews or worksites with several active areas may need additional facilities to maintain convenient handwashing access.

How Can You Protect a Portable Handwashing Station From Worksite Conditions?

Construction environments can expose equipment to dust, debris, moisture, temperature changes, and accidental impacts.

To help maintain the equipment:

• Clean the basin, faucet, and cabinet surfaces regularly.
• Protect the station from falling materials and unnecessary impacts.
• Prevent flooding or standing water from reaching electrical components.
• Inspect accessible fittings and connections for leaks or damage.

When freezing temperatures are expected, follow the manufacturer's winterization instructions. Water remaining inside pumps, heaters, or plumbing lines can cause damage.
