6 Things to Consider Before You Jet a Pipe

High-pressure water cleaning systems have become the tool of choice for maintaining sanitary sewer systems, because of their effectiveness in dealing with grease and sludge, along with their ability to partner with pipe inspection cameras. However, before you fire up your jetter and go off to battle underground monsters, there are six things to keep in mind.

1.    What the heck is down there?

•  Jetters do a great job on soft stoppages like grease, sand sludge, and even ice. However, when it comes to roots, they are not the preferred tool for the job. If you’re not sure what is happening in the line, you can try to send an inspection camera down to take a look, but if the line is blocked you won’t be able to see much. Remember, cameras can’t see underwater any better than you can. So how can you tell what the blockage is?

•  First, if the line in question has anything to do with food service, there is a better than even chance that grease is the problem. Using your powers of deduction, you can conclude that blockages in lines leading from restaurants, multi-family dwellings, and any kind of institution involving food service (schools, nursing homes) are likely to be made by grease and maybe rags. The same is true if the pipe in question originates in a factory or industrial facility that flushes lubricants, solvents, or any type of organic material down the drain. Also depending on where you are, sand can be a persistent problem.

 2.    Shake, Rattle, and Roll

•  Does your jetter unit have a way to vibrate the hose while it is in the pipe? The vibration function is used to break up the surface friction between the hose and the pipe, so you don’t get the hose stuck. One of the first things contractors noticed when they invented jetting some 40 years ago, was that when you connect a hydraulic hose and rear facing nozzle to a pressure washer and shove it down a pipe, there is a chance of getting the hose stuck. And anytime that happens it’s the beginning of a long day, because you’re going to need to get the excavator out. That is why every legitimate manufacturer of high-pressure jetters today has a feature that allows you to vibrate the hose while in use.

 3.    Yes, size matters

•  Are you using the correct size of hose for the pipe, you are trying to clear? Another excellent way to get your hose stuck in a pipe is by using the wrong size hose, which is surprisingly easy to do. When working with high-pressure water, the philosophy is to use the largest hose that will fit into the pipe. This is because hoses with a larger inside diameter don’t have as much pressure loss due to water friction. All things being equal, the larger the hose, the more pressure at the nozzle. The more pressure at the nozzle the easier it is to do the job.

 4.    Check your water

•  Since high-pressure water is doing the work down the line, it makes sense that you have enough of it. If you happen to be using a large device with a holding tank, such as a trailer jetter, your only challenge is to make sure the tank doesn’t run dry. Most of these units have an automatic shut-off that keeps this you from making this mistake. However, if you are using a jetter that draws water from a garden hose, a little more attention is required. Most municipal and well water systems in North America deliver approximately 5-6 gallons a minute in flow, but it is recommended that you make no assumptions. Get a 2-gallon bucket and measure how much time it takes to fill it. If you’re close, don’t take the chance, because you could accidentally starve the pump of water and cause cavitation. Cavitation is the second most popular way to kill your pump, so pay attention to details.

 5.    It don’t mean a thing if you don’t have that swing

•  Keep your hose moving. The preferred technique for jetting a line is to work the hose back and forth: push the hose 2 feet forward, then pull it back a foot, then push forward 2 feet and back a foot. The maximum cleaning action comes when you pull back the hose, not pushing it. As you pull back, the angle of water flow exiting the nozzle scours the sides of the pipe, magnifying your cleaning efforts. If you keep the hose moving, you’ll do a better job and do it in less time.

•  There is another reason to keep it moving. Because of the fluid dynamics of high-pressure water flow, turbulence can cause vortices to form just behind the nozzle when you are doing the job. These vortices, if stationary for any length of time, can suck sand, loose dirt, grease, or sludge in behind the nozzle, causing it to plug up and trap the hose down in the pipe. Getting your hose stuck in the pipe, no matter what the cause, is a bad thing. Digging it up is usually the only viable option. Again, very time consuming.

 6.    Don’t freeze up

•  Statistically, freezing is the number one way to kill your pump. If you live in a place with four seasons, you’ll find it surprisingly difficult to keep your pump from freezing when you are doing work on a frigid day. The damage can take place before, during, or after the job, and can affect your hose as well as your pump. If your unit has an antifreeze tank, please get in the habit of using it whenever temperatures are close to freezing. If your unit does not have this feature, introduce antifreeze to keep it from freezing when you are driving to and from the job. Just disconnect the hose that runs from the output valve to the hose reel swivel. Then pour antifreeze into the inlet as you start the motor on the unit, which will draw the fluid through the pump. When you notice antifreeze exiting the output valve, turn off the motor. Then, using an air compressor to blow the water out of the hose (remove the nozzle). Make sure this has been done before you drive to the job, and again before going back to the shop. During the job, limit the amount of time the units sits without water flowing through the pump. Turn the unit on frequently, running water through the bypass system to keep it warm. If you make it someone’s job to pay attention to the pump, then you’ll improve the odds of it surviving till spring.

•  You probably noticed that most of the points can be summarized by “paying attention to what you are doing” and “do your homework”. Jetters are fantastic tools for our industry, able to address most modern sewer line problems better than other tools at our disposal. But, like everything else in life, greater power comes hand in hand with greater responsibility. If you sweat the details, a jetter is an incredibly versatile and profitable tool that can transform your sewer maintenance program.

Accidents Involving Municipal Vehicles - Do Your Employees Know the Proper Actions to Take?

How does your municipality handle a vehicular accident when one of your employees is involved and operating a municipal vehicle? Being prepared and knowing what to do if this happens BEFORE it happens is key to promoting a successful outcome.

Do you have your employee contact their department supervisor? Police Department?  OMAG would certainly suggest a police report be filed, no matter how minor the accident. 

Do they know how to contact an ambulance service if needed?

Do they provide the information on your insurance verification card to the investigating officer?

Have they been advised to make no statement regarding fault at the scene?

Do they know how to assist the other party with the proper method to file a claim with the city?

If appropriate, do they take photos of the accident scene and all vehicles involved?

Are they advised not to make suggestions or recommendations on repair facilities? Making suggestions or recommendations on repair facilities can present uncomfortable situations if that repair facility does not meet the needs of the third party.

These things are very important to be sure that the investigation can be handled correctly. Regardless of whether the city employee feels they are at fault, a thorough investigation should take place to determine liability.  

If you have questions about how to handle a situation like this, or if you need help developing a plan, please contact Underwriting Director Chris Webb at cwebb@omag.org or Member Services Director Kyle Waid at kwaid@omag.org.

Can you delay designating paid leave as FMLA leave?

The Department of Labor issued an opinion letter today regarding the FMLA and whether an employer may delay designating paid leave as FMLA leave or permit employees to expand their FMLA leave beyond the statutory 12-week entitlement (26 weeks for military caregiver leave). The answer is "NO" on both questions. An employer may not delay the designation of FMLA-qualifying leave, even if the employee would prefer that the employer delay the designation. Additionally, an employer may not designate more than 12 weeks of leave (or 26 weeks of military caregiver leave) as FMLA leave.

HR Tip of the Month

Regularly audit your employee bulletin boards to ensure that all required posters are displayed.  There are both federal and state required posters that need to be displayed in your employee work areas.  OMAG can assist you with your bulletin board audit to ensure your city or town has everything posted.

Cleanliness Helps Prevent Foodborne Illness

Spring has long been the time of year for annual cleaning projects around homes and offices. However, when it comes to safe food handling, everything that comes in contact with food must be kept clean all year long.

Food that is mishandled or not stored properly can lead to foodborne illness. Follow a “Be Food Safe” policy. Being food safe means preventing foodborne illness by following four easy steps:

1. Clean – wash your hands and surfaces often and disinfect with food-safe Clorox wipes or Lysol.

2. Separate – don’t cross contaminate. Keep food covered in airtight containers or sealants.

3. Cook – Cook all foods to proper temperatures and don’t let them stay out in the open air too long.

4. Chill – Refrigerate promptly.

Cleanliness is a major factor in preventing foodborne illness. Even with food safety inspections and monitoring, the consumer’s role is to make sure food is handled safely after it is purchased. Everything that touches food should be clean. Here are some suggested steps to take to help prevent foodborne illnesses:

• Wash your hands with warm soapy water for at least 20 seconds

  • Before and after handling food

  • After using the bathroom

  • After changing a diaper

  • After handling pets

  • After tending to a sick person

  • After blowing your nose, coughing, or sneezing

  • After handling uncooked eggs, meat, fruits and vegetables

If your hands have any kind of skin abrasion or infection, always use clean disposable gloves. Thoroughly wash with hot soapy water any surfaces that have been in contact with raw meat, poultry, fish, or eggs. Use disposable paper towels to clean surfaces, not dishcloths or sponges. Spray or wipe surfaces with disinfectant after cleaning them.

Keep cutting boards clean, wash them with hot soapy water after each use, and then rinse and let air dry. Don’t use the same platter or utensils that held raw meat to serve the cooked product. When using a food thermometer always thoroughly wash it after each use with hot soapy water. Remember to keep pets, household cleaners, and other chemicals away from food and food preparatory stations. Keep refrigerators clean and sanitized; remove old food frequently. When eating out, eat at reputable restaurants and establishments. Avoid eating foods openly exposed in convenience stores like hotdogs, sausages, and taquitos – there are lots of germs floating around in those places.

Taking some time to “be food safe” could keep you and your co-workers or family from experiencing a very uncomfortable foodborne illness. Bon Appetit!

Bloodborne Pathogens - Protecting Workers

Every year municipalities, just like any other business, must train their employees about bloodborne pathogens. The following information can assist you in keeping your employees from contracting a bloodborne illness.

Bloodborne pathogens are infectious micro-organisms in human blood that include, but are not limited to, hepatitis B, hepatitis C, and HIV. The can infect a healthy body through contact with blood and other body fluids, secretions, and excretions (except sweat). In many cases, contact with infected fluids happens via used needles or other contaminated sharp objects that have not been properly disposed of or properly cleaned and disinfected.

Exposure Control Plan

All organizations where employees could be exposed to blood or other potentially infectious materials (OPIM) must follow the bloodborne pathogens standard. Employers are responsible for determining which jobs, tasks, and procedures involve an occupational exposure. According to OSHA standards, occupational exposure is a “reasonably anticipated skin, eye, mucous membrane, or parenteral contact with blood or OPIM that may result from performance of an employee’s duties.” If your workplace carries a risk of occupational exposure to bloodborne pathogens, you are required to develop an exposure control plan to minimize or eliminate occupational exposures. Start by identifying all the hazards workers may be exposed to. This exposure determination needs to contain a list of jobs with potential exposure and list of procedures that could result in worker exposure. Based on this determination, you should design and implement adequate safety controls using training, providing PPE, and administrative or engineering controls.

Implementing Controls

Elimination of hazards is not feasible in some workplaces. In these situations, it is important to follow basic controls. These controls can include, but are not limited to, the following:

• Use “universal precautions”; treat all blood or OPIMs as if they were infected.

• Implement safe practice controls; update and redesign them as needed.

• Practice safe decontamination; thoroughly wash and disinfect.

• Provide personal protective equipment such as gloves, masks, and specialized clothing if needed. Remember employers are responsible for repairing or replacing PPE when required.

• Implement engineering controls such as sharps disposal containers or needleless systems.

• Ensure that hepatitis B immunizations are available to all workers, that they have been properly trained and understand how they could be exposed, that they know how to protect themselves from exposure, and that they know what to do if they have potentially been exposed.

• Use warning labels and signs on containers and in areas where contaminated materials may be stored.

• Keep and update worker medical and training records regularly.

• Keep and update a sharps injury log.

Other Employer Responsibilities

After any exposure incident, arrange for a post-exposure medical evaluation and make it available to affected workers. Document the reasons for exposure and test the source individual (the person whose blood or body fluids contacted the worker) for hepatitis B or hepatitis C or HIV infections. Employers are also responsible for offering the exposed worker post-exposure prophylaxis and counseling.

The municipal exposure control plan must be reviewed and updated annually to reflect any workplace changes that might affect safe work procedures. Employers should also make changes to engineering and practice controls based on input from workers.

Workers must receive regular training that covers all aspects of the exposure control plan including who to report incidents to and how to decontaminate after a potential exposure. All new hires must be trained concerning how they could be exposed in their work environment and what to do if they think they have been exposed.

Although engineering controls are the primary method of reducing exposure, behavioral training also aims to achieve this goal by changing how workers perform tasks. When providing training, consider a program that deals with the human factors. This will increase employee self-awareness and help workers see how situations like fatigue and complacency may put them, their co-workers, or families at greater risk of contracting an illness from a bloodborne pathogen. Safety needs to be addressed from all possible angles to provide workers with the best protection available.

Airborne Diseases

You can catch some diseases simply by breathing. These are called airborne diseases. Airborne diseases can spread when an infected person coughs, sneezes, laughs, or even talks, spewing nasal and throat secretions into the air in particles of moisture. These particles take flight and land on people or surfaces, contaminating them. When you breathe airborne organisms in, they take up residence inside you. You also can pick up viruses or bacteria when you touch an infected surface and then touch your eyes, nose, or mouth. Because these diseases travel in the air, they are hard to control.

Some of the airborne diseases contracted by millions of people each year are: The Common Cold, Influenza, Chickenpox, Mumps, Measles, Whooping Cough, Tuberculosis, and Diphtheria.

Treatment for Common Airborne Diseases

For most airborne diseases the best treatment is getting plenty of rest and fluids and letting the illness run its course. Some diseases like chickenpox have no targeted treatment, but medications and other supportive care can help relieve symptoms.

Some, such as flu, can be treated with antiviral drugs. Treatment for infants with whooping cough can include antibiotics, but hospitalization is often needed. There are drugs to treat and cure tuberculosis, although some strains of TB are drug resistant. Failure to complete a course of medication can lead to drug resistance and a return of the illness. If caught early enough diphtheria can be successfully treated with antitoxins and antibiotics.

With our world being so easily accessed today with air travel, airborne disease can potentially affect everyone in a brief period of time. Diseases are spread easily in close quarters such as airplanes, schools, malls, and church gatherings. Take precautions: get plenty of rest, exercise, keep your immune system up by using supplemental vitamins, and avoid large populated areas when there is a known outbreak of disease. If you become ill, take some time off from work so you don’t spread the illness.

Insect Borne Illness

What are Insect Borne Illnesses?

Insect borne diseases are viral or bacterial illnesses contracted from insect (bug) bites. The most common insects that pass on disease are mosquitos, fleas, and ticks. Some common diseases known to be transmitted by insects are Zika virus, Yellow Fever, and Malaria from mosquitos, and Lyme disease and Rocky Mountain Spotted Fever from ticks (There are approximately 10 different diseases which can be contracted from a tick bite.)

Common Symptoms of Insect Borne Illnesses:

• Fever 

• Sore muscles    

• Nausea    

• Headache

• Chills      

• Skin rash          

• Stomach pain

More serious symptoms might include:

• Difficulty breathing

• Swelling/closing of the throat     

• Chest pain    

• Vomiting

• Swelling of lips, tongue, face    

• Racing heartbeat        

• Dizziness

How are Insect Borne Illnesses Diagnosed?

Your doctor can typically diagnose an insect borne illness with a physical exam, a review of symptoms, and checking recent travel destinations. Lab tests (blood and urine) can diagnose certain insect borne diseases.

How to Avoid or Prevent Insect-borne Illnesses

• Stay out of tall grass and bushes

• Dress in long pants and shirts and wear a hat; tuck pants legs into your boots or socks

• Wear light colored clothing, which makes it easier to spot crawling insects

• Use bug spray that contains at least 10% DEET

• Examine your skin and scalp after being outside, checking for bugs or bites

• Always shower using plenty of soap after being outdoors

Insect Borne Illness Treatment

As soon as you recognize a bite, clean it with soap and water. Pat it dry and apply rubbing alcohol to the bite. If bitten by a tick, remove the tick before cleaning the area. Use tweezers to slowly pull it off your skin. Be careful not to leave any part of the tick in/on your skin. Dispose of the tick. Wash your hands and the bite area with soap and water and then wipe with alcohol. Apply an over-the-counter antibiotic cream to the bite area.

If you have any of the symptoms listed above, see a doctor. If you start having flu-like symptoms 3-10 days after being bitten see a doctor for diagnosis.

Living with Insect Borne Illnesses

Some insect borne illnesses can cause long-term chronic symptoms that affect the quality of life. Lyme disease, for example, can leave you chronically tired and sore. Zika virus can be passed on to a baby and cause microcephaly and an intellectual disability.

Municipalities Must Take GHS-HazCom Training Seriously

The final GHS (Global Harmonization System) deadline is now long past. OSHA’s alignment of the HazCom (Hazardous Communication Standard) to GHS has provided a wakeup call to millions of companies across the U.S. to do a better job with their HazCom programs, especially when it comes to training. Unfortunately, not all Oklahoma municipalities have embraced this new standard. HazCom violations remain the number 2 violation on OSHA’s top 10 list of violations.

This article provides four steps employers can take to ensure employees understand the chemical hazards present in their work environments and to comply with GHS updates to HazCom.

• Step One: Build a Training Program Focused on Usefulness

  • While OSHA, and here in Oklahoma, the Department of Labor’s PEOSH division don’t specify how to do training, they do state that training must be effective. Employees must carry their learning into the workplace and be able to put it to use. HazCom has two key components: 1) providing employees with a basic understanding of the HazCom standard (OMAG works with many of our cities and towns to provide this understanding.); and 2) training employees on the specific hazards of the chemicals to which they are exposed and providing protection through administrative controls, engineering controls, and personal protective equipment (These are the responsibility of the employer and its departmental supervisors.)

  • In the past, HazCom with GHS focused on training workers to understand the new SDS (safety data sheets) and labeling formats accompanied with GHS adoption. However, many employers lacked a basic level of understanding about HazCom (municipalities included), making it difficult for them to comprehend and address the changes brought by the new GHS alignment. As a result, workers were never adequately trained on HazCom in the first place or had been trained so long ago that what they learned had been forgotten. It is critical that employers continue to emphasize basic HazCom training, which now includes GHS information to ensure employees are able to use the information in their day-to-day activities.

  • The second component of an effective HazCom training program focuses on the individual hazards employees face. Departmental supervisors must train their employees on the specific chemicals used and their hazards. The key here is to provide employees with a deeper understanding of the dangers and emergency situations they face, and counter them by following written policies and procedures.

• Step Two: Deliver Training So Employees Can Understand It

  • When OSHA first published the HazCom Standard in 1983, it followed the concept of the employee’s “right to know” about the hazards to which they might be exposed. A primary driver for OSHA’s adoption of the GHS has been the desire to improve employee comprehension of critical chemical safety information.

  • With GHS, OSHA is indicating it’s not enough for workers to just know about the hazards; instead they have the “right to understand” those hazards and know what related safety precautions to take.

  • The pre-GHS employee “right to know” concept often translated into giving workers access to MSDSs and labels and making sure they were aware of the hazards that existed from chemicals in their work environment. This approach didn’t always translate to employees understanding the safety and health information being conveyed on the MSDS and labels. GHS adoption helped solve this issue by bringing harmonization and consistency to the structure of the safety data sheets (formerly MSDS, now SDS) and labels. Use of standardized hazard communication elements, such as pictograms, make it possible for workers to more easily understand the hazards associated with chemicals workers use or are around. This simplified approach to communicating hazard information makes it possible to protect workers of all backgrounds. For instance, pictograms make it easier for illiterate and non-English speaking employees to understand the nature of a product’s hazardous properties.

  • The “right to understand” concept compliments OSHA’s rule on employee HazCom training – that it must be presented in a manner all employees can comprehend and retain. When applied to HazCom training, this means that employees who work with or around hazardous chemicals must receive training in a language they can understand, even if the documents (SDSs and labels) are only required in English.

• Step Three: Provide Easy Access to SDSs

  • A key aspect of HazCom training is to make sure employees know how to get direct access to Safety Data Sheets (SDSs) and other hazardous chemical information. Some employers are using electronic solutions to help employees retrieve information from their inventory of SDSs. If this is true with your municipality, it is incumbent on you to make sure employees are made aware of the system, how to access it, and how to use it. Without that access, in the event of an emergency, even an employee that has received adequate training on labels and SDSs will still be at risk should a chemical event occur that requires quick action. For that reason, many employers are taking advantage of technological advancements and using mobile solutions to put SDSs in the hands of their employees. The best Environmental, Health, and Safety (EHS) software solutions today leverage the cloud to make critical chemical safety information available anywhere, any time. One problem with using technology solutions, however, is many municipalities don’t have the financial resources to provide such innovative techniques. Therefore, keeping updated SDSs available to workers in a binder within the work environment of the workers may still be the best way to provide them with quick environmental, safety, and health information when a chemical event occurs. These binders can be kept in trucks, shops, and offices - wherever the employee has access to them.

• Step Four: Keep It Consistent

  • While OSHA and OK DOL-PEOSH don’t require employee training to be performed in specific intervals of time, regular training (at least annually) is a best practice to help ensure your employees better retain HazCom with GHS information. Other instances for training may include newly hired employees, temporary employees, visiting contract workers, or when a new chemical is introduced to a department. This helps ensure that employees who might work with or around a hazardous chemical understand its potential hazards.

It is vitally important to view HazCom and GHS training as an ongoing obligation. Over my years of travel around the state performing inspections and trainings for OMAG shareholders (cities and towns), I have personally noted frequent inadequacies with regard to HazCom and GHS training and information resources. The safety of your employees must be a priority in your day-to-day operations for their sake, for your municipality’s sake, and for the health and welfare of the state of Oklahoma.
