Key Environmental Benefits of Portable Restrooms

At One Site Companies, we provide only the most experienced knowledge and sources for portable sanitation systems. Portable restrooms offer several benefits on top of providing a safe, sanitized, and easy to use private environment for users.

In our mission, we would like to provide insight for you on how portable restrooms also have huge environmental benefits for users.

Conserving Water

Flushing is the largest daily use of water in the United States, including showering and hand washing. Portable restrooms conserve water since they don’t require flushing after every use. According to the PSAI 45 billion gallons of fresh water are saved annually by portable restroom use.

Protecting Landscaping and Waterways

Portable restrooms help preserve the surrounding landscaping by saving plant life from harm due to individual waste on bushes and trees. They also prevent human waste from reaching streams where it can poison certain bodies of water, harming local flora and wildlife. Portable restrooms keep human waste safely contained until it is disposed of for treatment, protecting the surrounding natural environment.

Reduced Insect Problems

Containing human waste in portable restrooms helps prevent the problem of insects swarming to the waste. If a person’s waste contains any parasites, they could end up in the soil when not properly contained in a portable restroom. This could potentially infect someone else who came into contact with the waste and cause damage to the environment.

Preserving Public Health

Various diseases spread through the transfer of fecal matter to the mouth. When someone does a bowel movement, but fails to wash their hands properly, and then touches objects such as utensils or food, the germs can spread and cause sickness. The same is true for urinating without washing the hands. Portable restrooms with hand sanitizer or soap dispensers and running water solve this problem. Otherwise, individuals at various outdoor events are forced to go to the bathroom in the bushes somewhere without an opportunity to sanitize themselves, including their hands.

Odor Control

The design of portable restrooms today includes better odor control than older generation porta potties. Here at On Site Companies, we use hospital-grade disinfectant to clean our units and take great measures to ensure a pleasant experience. This means that regardless of whether or not it is the type of mobile restroom that flushes, it will not spread an unappealing aroma to areas of your area, even if you have multiple portable restrooms set up throughout your venue.

New OSHA Heat Hazards Regulations

New OSHA Heat Hazards Regulations - Blog

For the first time, the Occupational Safety and Health Administration (OSHA) has launched a National Emphasis Program (NEP) to protect workers from injuries and illnesses caused by heat hazards. OSHA’s new NEP ramps up the inspection and enforcement of workplaces in industries deemed to be high risk for heat stress. Appendix A of the NEP Document outlines the list of 70 industries affected. Here is everything you need to new about the OSHA’s new EPA.

What Are the New OSHA Heat Hazards Regulations?

OSHA’s inspections prioritize sites with complaints of employer-related heat hazards. Additional inspections occur on days the National Weather Service issues a heat warning or advisory local to that area. Employers to inspect are randomly selected from the list of high-risk industries. On “heat priority days” when the heat index is 80°F or higher, OSHA field staff initiate compliance assistance to help employers keep workers safe on the job. Also, during these days, OSHA inspectors search for and address heat hazards during inspections of all workplaces, regardless of their industry.

The compliance safety and health officers (CSHOs) review records of heat-related employee incidents. They interview workers for symptoms that may indicate heat-related illnesses or injuries. Working conditions that could contribute to heat stress such as dealing with hot air or driving a hot vehicle are recorded. Workers’ proximity to furnaces and other hot equipment are noted. They also identify the use of heavy or bulky equipment, including personal protective equipment (PPE). CSHOs categorize the exertion of work depending on the duration and level of strenuous activity. They take both average and peak workloads into consideration.

Under the NEP, OSHA has not set any specific standards to comply with. This is because the stages of official rule-making can take multiple years. The NEP is an initiative to make progress while the new rules finalize in court. Although there are no specific guidelines to follow yet, they have outlined general ways to comply in their documentation. The NEP starts on April 8, 2022 and will continue until April 8, 2025 unless cancelled or extended.


How Do I Comply with the Standards of These Inspections?

Create a written plan for heat hazard prevention and response. Define how you plan to monitor the heat index of your site and its impact our your workers’ safety. Next, make sure to outline the precautions you are taking to prevent heat stress. Record all incidents, complaints, and concerns with heat illnesses or injuries. Then, document a clear procedure on how to respond to these cases and clearly note each occurrence.

According to Appendix B of the NEP, CSHOs will ensure that the air conditioning is adequate enough to provide a cool place to rest during weekdays. In Appendix D, as an example it is recommended to use air conditioning, proper ventilation, and cooling fans. However, it is also noted that you should tailor your efforts specifically to what you need at your site. Renting portable air conditioners, air filters, and fans/air movers is a great way to be safe and help prevent heat hazards. If you are in the Midwest, On Site Companies is a great resource for these types of climate control rentals.

Schedule rested breaks for hydration and provide access to unlimited cool water for your staff. Give access to shaded areas for employees that spend work time outdoors. Consider using earlier or later start times with rotating shifts to limit exposure to sun. Make sure to give proper PPE, including breathable clothing, as well as hats and sunglasses to protect from the sun.

Provide your staff with training and resources for heat hazard education. Train them on topics such as the symptoms of heat illness, heat stress prevention, the importance of hydration, first aid, and emergency response procedures. Also, consider using a “buddy” system for staff to check in with each other.


What Are My Resources for OSHA Heat Hazards Compliance?

The full NEP linked above contains all of the new policies in entirety. However, this NEP Fact Sheet summarizes the most important information into one page. For more in-depth rational and data behind the reasoning for these changes, OSHA references the CDC’s publication, Criteria for a Recommended Standard: Occupational Exposure to Heat and Hot Environments.

OSHA’s area offices are engaging with unions, employers in “high risk” industries, and other advocacy groups for assistance. Their On-Site Consultation Program is a free resource for small and medium-sized businesses. This is separate from and does not result in punishment from OSHA. Consultants work with employers to identify potential hazards and assist in developing plans for OSHA compliance. Employers can request this program by contacting their local consultant.

The Heat Illness Prevention Campaign educates employers and employees on the dangers of heat stress. On their website, OSHA has additional information on the dangers of heat exposure and how to prevent heat stress. Use the Health Safety App to calculate the heat index and view the risk level of your job site on your phone. The OSHA Technical Manual (OTM) is another great resource for training on health, safety, and construction hazards. Also, the National Heat Integrated Heat Health Information System (NHIHHIS) has several helpful tools and articles to assist in your heat hazard prevention plan.

Portable Restrooms for Graduation Parties

Portable Restrooms for Graduation Parties - Blog

Most people don’t even consider renting portable restrooms for graduation parties as an option when planning their big day. Whether you are hosting your grad party at your home or a public venue such as a park, portable restrooms are sure to make your guests have a better experience. Here are the top three reasons why our customers decide to rent porta potties during grad party season.


1) Keep Your Guests Comfortable

We all know how uncomfortable it can be to wait in a long line for the restroom. This problem starts to become apparent at events of 50 people or larger, especially when alcohol is served. This is why using portable restrooms for graduation parties is a good idea. Are you unsure of how many portable restrooms would be the perfect amount for your event? Use our calculator on our portable restroom page (scroll to the bottom). Just answer the questions provided and an amount of portable restrooms will be recommended to you.


2) Control the Traffic of Your Grad Party

If you are hosting your graduation party at your home, you may not want guests constantly walking in and out of your house just to use the restroom. They can track in dirt and grime if they don’t take off their shoes. Having guests constantly in motion can also be a disruption for anyone that’s lounging inside. Using porta johns allow you to control the traffic of the event. You can keep the majority of the guests outside, so anyone indoors can mingle in peace. If your event is in a public place such a park, this will also keep other visitors happy.


3) Portable Restrooms for Graduation Parties Keep Your Guests Safe

After the rise of COVID-19, the world has seen the importance of sanitation and social distancing. Portable restrooms allow guests to maintain their personal space while waiting to use the restroom. Having a sufficient number of portable restrooms will ensure that you won’t run out of valuable sanitation supplies such as hand soap, hand sanitizer, paper towels, and toilet paper. Hand sanitizer stations are a great source of additional sanitation. Portable hand wash stations are also great to keep your guests clean when food is served.


4) Bonus: Combine Portable Restrooms with Other Portable Equipment

As mentioned above, hand sanitizer stations and hand wash stations are a great addition to any grad party. Cardboard trash boxes are a great cost effective solution to collecting the waste from food and beverages that are served. Is your event taking place in a tent? Consider renting a portable air conditioner. Also, consider using misting fans to keep your guests cool outside as well.

The Portable Sink with Hot & Cold Water

The Portable Sink With Hot And Cold Water - Blog Banner

On Site Companies’ SaniSink is the perfect portable sink that provides both hot and cold water! This portable sink is a standalone unit that allows users to take control of their water quality by hooking up directly to a 5 gallon water tank. The sink needs one standard 100/120v outlet to connect to for power and an additional empty water tank to store used water.

This mobile sink can be used as your all-in-one hand washing station. It features attached soap and paper towel dispensers. Connect the SaniSink with a 5 gallon purified water tank to have a source of safe, clean drinking water. Common uses include hospitals, offices, commercial remodels, concession stands, camp grounds, and more!


Use a Portable Sink with Cold AND Hot Water

Just because your sink is mobile, doesn’t mean that you lose access to hot water. The SaniSink contains a water heater that allows users to control the temperature of their water during use. There are two separate handles for “cold” and “hot” water just like a stationary sink.

Since the SaniSink is a portable sink with a tank, all of your water is guaranteed to be fresh. However, this is only true if you use our recommended 5 gallon tank of purified water as opposed to attaching to a hose. All of the used water will dispense out of the backside of the sink. We recommend using another empty 5 gallon tank for easy capture and disposal of the used water.



Take Control of Your Portable Sink’s Water QualityInside of portable sink

Stationary sinks and mobile sinks that rely on connecting to public water systems put users at risk for drinking unsafe water. Mobile sinks that require a hose to connect to public tap water gives the user no control over water quality. Drinking contaminated water can cause sickness or even severe heath issues  for instance.

However, the SaniSink is a portable sink that allows you to control the water source. We strongly recommend using a 5 gallon tank of purified water. This will assure that the water source of your portable sink is clean and safe for drinking.


Wash Your Hands with Convenience

The set up of the SaniSink is very easy. All you need is a 5 gallon tank of purified water, an empty 5 gallon tank, and access to a standard 100/120v outlet. First, hook up the filled water tank to the water dispenser inside the sink. Afterwards, connect the empty water tank to the hose that dispenses the used water in the back of the sink. Finally, just connect the plug to a standard electrical outlet and you are ready to go!

This portable sink has other features that makes it very convenient. Control the temperature with the labeled “hot” and “cold” handles. Use the soap dispenser that is attached to the sink for washing. Finally, complete your wash by drying off with the paper towels from the attached dispenser. This all-in-one mobile sink makes hand washing a breeze!

How to Prepare Your Job Site for Spring

How to Prepare Your Job Site for Spring

Being proactive is the best way to prepare your job site for the spring. We recommend that you do so as soon as possible to ensure that the right solutions will be available when you need it. Here are the top 5 must-haves for any job site as the weather begins to change.

1) Dehumidifiers

Whether it’s melting snow and ice from the winter or the April showers that bring May flowers, dehumidifiers are a must-have for your job site. Having dehumidifiers ready to go will keep that moisture away from your job site that makes it harder for your team to work.


2) Air Conditioners

When spring rolls around it’s time to put away the heaters and bring in the air conditioners. Having a cool job site will keep your employees safe and comfortable enough to work efficiently.


3) Air Filters

Having access to air filters to remove any harmful particles, odors, and chemicals that reach your job site is essential to keeping everyone safe. This is particularly important during wet spring months when mold and dust mites can accumulate if moisture isn’t addressed proactively.


4) Air Movers

Air movers such as prop fans, exhaust fans, and carpet blowers make a great addition to any job site. They increase the efficiency of the equipment discussed above by controlling the air flow and can also be used to help dry out any moist areas.


5) Portable Restrooms for Job Sites

Portable restrooms are essential to any job site to keep your team comfortable. Having employees use off site restrooms can be extremely expensive when you account for the increased time of restroom breaks. Standard restrooms are great, but mobile units, hook units, and high rise units are a game changer.


The On Site Solutions

On Site Companies has all of the above solutions help you prepare your job site for spring. It is never too early to begin planning for warmer weather. We recommend that our customers do so to ensure that we have the right solutions for you available when you need it. Call us today to discuss your needs – we would love to provide you with a quote specifically tailored to your job site.

Portable Restroom Use in the Winter (Q&A)

Portable Restroom Use in the Winter (Q&A)

A lot of people assume that they can not use a portable restroom in the winter. They think that it isn’t possible due to the cold weather making the unit freeze. This is one of a few misconceptions that arise in the sanitation industry. Check out this guide for answers to common questions we tend to receive once the temperature begins to drop.

Can I use a portable restroom during the winter?

You can most definitely rent a portable restroom during the cold winter months. We have the infrastructure and proven processes to prepare your special event or job site for freezing temperatures. Cold weather will not stop you from enjoying portable sanitation.

How do you prevent a portable restroom from freezing?

We have several proven processes to prevent your portable restroom from freezing. We fill the tanks of our restrooms with a methanol mixture that will prevent water and waste from freezing. Our urinals are salted to prevent moisture from freezing as well. We recommend including portable restroom electric space heaters to your rental order to help keep your guests or employees warm.

Can I rent a luxury restroom trailer during the winter?

Some of our luxury restroom trailers are available for rent for cold weather outdoor use by using our Winter Packages that includes access to extra 110V – 20 AMP electrical circuits, Premier 170 heater, skirting, & heated hoses.

Our On Site Suite, Commercial Prestige, Versa, Comfort Station, and Prestige are all compatible with our Winter Package. Please contact us for more details.

Can I rent a luxury shower trailer during the winter?

Unfortunately, luxury shower trailers can’t be used outdoors during the winter. There’s too much running water in showers to be able to separate our methanol mixture that prevents freezing from potable water that is safe to bathe with. Consider placing the shower trailer indoors if you have access to indoor space.

How can I keep the ground from freezing or thaw frozen ground?

We have a wide selection of ground thawing units that can prevent the ground from freezing or thaw freezing ground. We recommend including ground thaw blankets to your rental order to maximize the efficiency of the heaters. This equipment can also be used to cure concrete during the winter as well.

How can I keep my entire special event or job site warm in the winter?

We have a wide selection of temporary, portable heating equipment to keep your special event or job site warm during the colder winter months. Please contact us for more information and how we can satisfy your unique needs to keep everyone warm.

Troubleshooting 101: Portable Heaters

Top 5 Benefits of Using Methanol for Portable Restrooms

Troubleshooting portable heaters can be a difficult task. Just because your portable heater won’t start up doesn’t necessarily mean it’s broken. If you are using On Site Companies’ products and you run into this issue, be sure to use this helpful guide below to test why your equipment isn’t working.

If you are renting from us and are still unable to start your portable heater after carefully following the instructions below, please contact us at 651-429-3781 to schedule an On Site Heat Technician to be dispatched immediately.

Troubleshooting Portable Ground Heaters

  • Make sure there is power to the machine
  • Make sure there is fuel in the machine
  • For the E1100 – make sure to wrap fuel tank and fuel filter with extra hose and blanket to avoid fuel gelling
  • Make sure the unit is level – if not, machine may be showing a false low level fault
  • Check to make sure there is nothing laying on the lines
  • Be sure the pump is running (check flow meters – a.k.a. spinning dials) to make sure they are turning:
  • 1) If not pumping – check for low level fault light located on control panel
  • 2) If in low level fault – there may be a leak
  • Check for leaks
  • Make sure the burner is on:
  • 1) Check burner fault module located on the side door (green button and red light)
  • 2) Press and hold green button for 45 seconds to try and reset


Troubleshooting Standard Portable Heaters

  • Make sure the start button has been pressed
  • Be sure the heater is plugged in to a dedicated 120v / 20amp outlet
  • Check to see if the GFI/breaker has been tripped
  • Be sure the thermostat is set high enough to call for heat
  • Be sure the gas is on:
  • 1) For propane – check the valve to the tank and also the “t” valve right after the red regulator
  • 2) For natural gas – check the “t” valve right after the meter
  • If you are burning propane check to see if there is at least 20% in the tank
  • Be sure there are no materials blocking the front or back of the heater
  • Check to see if the hose is kinked or if there is anything on it such as lumber, vehicles, etc.
  • Be sure gas selector valve is in the correct position if applicable (natural gas or propane)
  • Be sure all extension cords are grounded
  • All ductwork must be straight to maintain constant air flow


We also have portable heater troubleshooting videos for a dirty flame sensor rod, dirty spark plug, and bad fuel connection.
