OSHA Requirements for Pumpers

It’s never a bad time for a refresh on the requirements of the Occupational Safety and Health Act (better known as OSHA). The act, passed in 1970, comprises a set of federal standards for workplace safety, but it also allows individual states to submit and operate their own safety plans and requirements. State plans may cover all workers in a state, or may only cover state and local government workers only. It is important to know which category your state falls under.

OSHA state plans covering private and state/local government workplaces:
Alaska, Arizona, California, Hawai’i, Kentucky, Indiana, Iowa, Maryland, Michigan, Minnesota, Nevada, New Mexico, North Carolina, Oregon, Puerto Rico, South Carolina, Tennessee, Utah, Vermont, Virginia, Washington, Wyoming

OSHA state plans covering only state/local government workplaces:
Connecticut, Illinois, Maine, Massachusetts, New Jersey, New York, Virgin Islands

No state plan, follows federal OSHA plans:  
Alabama, American Samoa, Arkansas, Colorado, Delaware, Florida, Georgia, Guam, Idaho, Kansas, Louisiana, Mississippi, Missouri, Montana, Nebraska, New Hampshire, North Dakota, Northern Mariana Islands, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Dakota, Texas, Washington D.C., West Virginia, Wisconsin

State plans often don’t differ drastically from the federal OSHA plan, but the states of California, Michigan, Oregon, and Washington do have plans with substantial differences from the federal one.

If you are in need of assistance in identifying and/or fixing workplace safety issues, most states do have consultation services available for free as part of the On-Site Consultation Program. Other OSHA programs workplaces can participate in include the Alliance Program, the OSHA Strategic Partnership Program, the Voluntary Protection Programs, and the OSHA Challenge Program.

Read more about the OSHA cooperative programs here >>

Keep in mind that the supervisor or crew leader of an onsite/decentralized wastewater work crew will typically be the OSHA competent person (unless there is a different employee specifically assigned to oversee safety). Whoever is in charge of safety, they must be able to identify critical issues, know and follow OSHA requirements, enforce a written safety plan, and create a culture of safety for the workforce.

The top reasons for accidents include rushing, poor concentration, and simply being in the wrong place at the wrong time. A comprehensive safety plan can help address some of these causes and minimize damages after accidents do occur.

Health and Safety for Onsite Workers | Onsite Overview #2

Onsite professionals are exposed to many dangers on the job, and it is important to be aware of all the appropriate health and safety precautions that will keep workers (as well as the general public) safe. Outside of the day-to-day risks that decentralized wastewater workers must face, there is also the concern of public and environmental health when septic systems are not maintained and repaired correctly. We have compiled a list of resources to get you started if you are interested in learning more about decentralized wastewater systems and how they can affect health and safety.

Our best resources on this topic:
“More Than Just Dirty” Pathogen Exposures to Workers in the On-Site Industry | Washington Onsite Sewage Association
This 107-slide presentation provides research results on a study conducted to examine pathogen exposures to workers in the on-site industry, discuss the various types of pathogen exposures and health impacts, what kind of personal protective equipment (PPE) is available to on-site workers, and basic hygiene practices to reduce risks from handling human waste.

Septic Tank Lid Safety | Washington State Department of Health
This 1-page fact sheet has a list of 7 precautions to make sure no one accidently falls into your septic tank. This includes knowing where your septic system lids or covers are located, use bolts, screws, or other locks to secure the lids and prevent easy access, teach children that the septic tank lids are not to be played on or opened.

What is a Cesspool? | Wastewater Alternatives & Innovations
This 3-minute video describes what cesspools are, and why they need to be converted. Basically, a cesspool is a hole in the ground receiving untreated wastewater. Cesspools pollute the environment and endanger public health. The focus is on Hawaii since they have the greatest number of cesspools per capita for a total of 83,000 in the state that are planned to be converted by 2050.

Decentralized Wastewater Treatment Can Protect the Environment, Public Health, and Water Quality | U.S. Environmental Protection Agency
This 2-page fact sheet describes how a decentralized wastewater treatment system can provide reliable wastewater treatment, reduce conventional pollutants, nutrients, and emerging contaminants, and mitigate contamination and health risks associated with wastewater. A case study on where this worked is also provided.

The Need to Mandate Openings at Surface on Septic Tanks | National Onsite Wastewater Recycling Association
This 20-page presentation points out the common problem with access to septic tanks. Septic tanks are often installed without clear indications as to their locations and/or depths, creating several issues that should be addressed in order to properly maintain our waste management systems. Potential risks include the contamination of groundwater as potential injury to workers, homeowners, and the general public. The proposed solution is to install risers with covers to the surface as a reasonable way to assure proper maintenance.

Best Practices for In-Person Training During COVID-19

By Jill Wallitschek

To provide operators with continuing education opportunities during the pandemic, many training providers have adapted their classes to virtual training. These efforts have resulted in new online training opportunities and have allowed operators to earn their much-needed continuing education credits. Despite these efforts, not all training topics can be offered in an online format to all operators. Some training topics require equipment demonstrations and hands-on practice. In addition, some operators have limited internet access or may find it difficult to learn in an online setting.

For these reasons and others, some training providers have returned to an in-person training format. In this post, we have summarized COVID-19 safety trends our staff have observed from training providers as they resume in-person training. Using these trends, as well as CDC guidelines, we have provided a compiled set of recommendations to protect operators registered for in-person training.

Looking through training registration webpages and memos posted regarding the resumption of in-person training, the bulk of training providers have noted that they intend to follow local, state, and federal safety guidelines during class and in preparation of the class. This generally includes social distancing, the requirement of masks, and a restriction on the number of registrants per class. Many providers will also require students to fill out a COVID-19 screening checklist as well. Training providers of colleges or areas with higher infection rates trended to have stricter and more detailed guidelines. Classes developed around the use of hands-on equipment such as backflow prevention workshops, developed specific guidelines for how equipment will be maintained during the course.

The most thorough training providers include safety information about instructor requirements, student requirements, and facility requirements. Some of these trainers designated their own hotline to report cases or ask additional questions about COVID safety.

Based on our review of these recommendations, we have put together “best of” guidelines that training providers can use to protect their operators.

Classroom Preparation:

• Training will follow federal, state, and local guidelines
• Prepare the facility according to CDC Facility Disinfection guidelines
• All employees should be trained and certified on personal hygiene and surface sanitation/ disinfection procedures. See the Disinfecting Your Facility guidance by the CDC.
• Instructors are to remain at least 6 feet away from students
• Set up the chairs or workstations no less than 6 feet apart
• Provide hand sanitation stations throughout training facility
• Place posters in popular areas that encourage hand hygiene
• Specify entrances and exits through signs or floor tape
• Ensure that the check-in table provides a notice to:
  • Require mask use and proper hand hygiene
  • Inform of hand sanitizer stations
  • Prohibit handshakes, encouraging other noncontact greetings
  • Direct employees to visit the CDC’s coughing/sneezing etiquette and clean hands webpage
  • Inform guests of specified entrances and exits visible for the use of classes
  • Request students fill out pre-screening questions
• Training will be rescheduled or moved if the host site experiences an active COVID-19 case within the 2 weeks of class

Classroom Maintenance:

• Disinfect common surfaces (doorknobs, bathroom fixtures, classroom tables, chairs, etc.) before class, once mid-morning, once mid-afternoon, and after students leave for the day
• Limit bathroom use to one or two people at a time to maintain social distancing
• Suspend food consumption or drinks inside classroom
• Suspend food service or offer pre-boxed meals during breaks
• Require students eat outside or in designated areas set up for social distancing.

Student Requirements:

• Students should be directed to review safety requirements and pre-screening questions prior to the training
• Upon arrival Students should be directed to fill out a liability waiver acknowledging the measures taken by the training provider to prevent the spread of COVID-19, their compliance, and who should be held liable if illness occurs. An excellent example of this waiver was developed and used Arkansas Rural Water Association. Such waivers can require that:
  • Students must wear a mask according to CDC guidelines
  • Additional PPE, including protective gloves, may be required during certain tasks
  • Students must follow social distancing guidelines to maintain 6 feet of distance between the instructor and other students
  • Students will wash hands frequently for 20 seconds avoiding contact with the eyes, nose, or mouth
  • Students follow appropriate coughing etiquette
  • Students must refrain from eating or drinking in the classroom
  • Students will adhere to all safety guidelines set by training provider
• Upon arrival Students should read and sign a prescreening questionnaire that certifies:
  • I am not experiencing any symptom of illness such as cough, shortness of breath, difficulty breathing, fever, chills, repeated shaking with chills, muscle pain, headache, sore throat, or new loss of taste or smell
  • I have not traveled internationally or out of state within the last 14 days
  • To my knowledge, I have not been exposed to someone with a suspected and/or confirmed COVID-19 case in the last 14 days
  • I have not tested positive for COVID-19 in the last 14 days
• If resources provide, students will have their temperature checked before entrance. Students with temperatures above 100ºF will be denied.
• Students should bring their own writing utensil, books, paper, and calculator. No sharing is permitted.
• If diagnosed with COVID-19 or exhibiting symptoms within 2 weeks of the training or if exposed to COVID-19 during the training, students must notify the training provider

Equipment Expectations:

• Instructors observing student(s) must remain 6 feet away from the testing station and student
• When hands on equipment is used, attendees will get their own piece of equipment that stays in class
• Each cart and testing station will be routinely cleaned, sanitized, and disinfected before the start of class and after each session
• All tools and test kits will be routinely cleaned, sanitized, and disinfected before the start of class and after each student has complete

While continued training opportunities are important, the health of our essential workers must be priority. WaterOperator.org hopes that all training facilities offering in-person classes are taking every possible to protect their students.

A note to our operators: If you’re looking to attend an in-person training, investigate the training provider safety measures before registration. If these measures aren’t available online, it’s always best to call ahead. WaterOperator.org lists live, online and in-person training opportunities in our national training calendar.

Developing & Implementing a Cost Effective Water Utility Safety Program

Even with advances in smart water technology, any supervisor knows that a utility can't run without its dedicated staff. While workers take care of equipment operations, maintenance, billing, or customer service, it's the responsibility of the person in charge to ensure these duties are being carried out in a safe environment using appropriate precautions.

Water and wastewater utilities have a history of experiencing occupational injuries, illnesses, and fatalities (IIF) at a higher rate than most other occupations. The Bureau of Labor Statistic’s Incidence Rates - Detailed Industry Level table from each year’s Industry Injury and Illness Data Summary Tables has generally supported this trend. Their reports show the average non-fatal incident rate for the water and sewage industry has historically been higher than the industry average as a whole.

The data from this table was taken from the Bureau of Labor Statistics Incidence Rates- Detailed Industry Level for 2008 and 2017. (Click table to enlarge.)

The table above shows the rate of non-fatal injuries reported by the Bureau of Labor Statistics in 2008 and 2017. While any year can have variability, in 2008 the non-fatal injury incident rate was much higher than the industry average. In 2017 you can see that the average number of injuries has decreased since 2008 and is now closer to the industry average. These values don’t include the number of fatal injuries experienced by the water and wastewater industry, but as an overall trend, non-fatal injury reports to the Bureau of Labor Statistics support that the water industry has improved since the early and late 2000’s.

Types of Injuries
As utilities continue to prioritize and promote a safe work culture, we hope to reduce the frequency of incidents even further. There are many hazards that pose a risk to operator safety. The most frequent non-fatal water and wastewater injuries reported by the Bureau of Labor Statistics in 2017 were due to over exertion during lifting, being struck by a tool or object, and falls, slips, and trips. Water and wastewater utilities also have to manage the risks posed by confined spaces, electrical equipment, trenching, road safety, ladders, hazardous chemicals, blood borne pathogens, and more.

Safety Costs
According to Bureau Veritas’ presentation at the 2008 CSWEA Maintenance and Safety Seminar, the financial costs for water and wastewater injuries can be quite expensive. Budgeting for a good safety program will protect your employees and incur less expenses than the direct and indirect costs that result from a poor safety program.

Developing and Implementing a Safety Program
Since every system faces different hazards, your safety plan should be specific to your system hazards. To get started, the Occupational Safety and Health Administration (OSHA) recommends seven core elements for your system’s safety program: management leadership, worker participation, hazard identification and assessment, hazard prevention and control, education and training, program evaluation and improvement, and communication and coordination for host employers, contractors, and staffing agencies. OSHA’s Recommended Practices for Safety and Health Programs website provides an explanation of these elements in addition to a list of helpful tools, case studies, additional resources, and a download for the recommended practices guide.

We also encourage you to check out the Water Research Foundation’s Water Utility Safety and Health report to review safety program best practices and cost evaluations for various proactive and reactive programs. Once you’ve done your research, West Virginia Rural Association has developed an Injury and Illness Prevention Program template that systems can expand from.

Water System Specific Hazards
As you continue to promote safety in the work place remember that complacency is the adversary to injury and accident prevention. More specific  guidelines for electrical safety, traffic control, hazardous material communication, competent persons, confined space, chemical handling, chlorine exposure, fires, and waterborne disease can be found in Chapter 8 of the Alaska Department of Environmental Conservation’s Intro to Small Water Systems Correspondence Course. The OSHAcademy also offers a variety of water and wastewater specific safety training. If you have a different safety question, more resources are available at WaterOperator.org’s document library or under our blog post category Operator Safety.

Methane Safety at Wastewater Plants

Last week, a large explosion at a water reclamation facility in Calumet, IL served as a somber reminder of the importance of following safe practices when dealing with methane gas or any flammable material at treatment plants. While no one was killed, there were injuries and some of these were severe.

With this in mind, there is no better time than now to review safety procedures and training practices for working around potentially explosive materials like methane.

An important first safety step, according to this Spring 2018 article in Missouri WEA's Current Magazine, is to check your facility for gas leaks and accumulations. When doing this, it is better to use a combustible gas meter than to rely on your sense of smell, because an individual's nose can become desensitized to the tell-tale rotten-egg smell over time. In addition, it is essential that workers know how to use monitors properly, and test them regularly.

Other recommendations include the installation of an automatic fan/ventilation system and a permanent gas detection system.

Finally, as this safety presentation from Suez points out, never perform hot work unless explosion risks have been identified and eliminated. If you need a visual reminder about why this is so important, this video from the US Chemical Society & Hazard Investigation Board (USCSB) lays out the events leading up to a fatal Florida wastewater plant explosion in 2006.

Gas and chemical hazards are an invisible but unavoidable fact in the operations of a wastewater treatment plant. Get a step ahead of the game by reviewing these tips and following the correct protocol - it's the best way to ensure that you return home safely each workday.

Focus on Chlorine Safety

Chlorine is one of the most widely used industrial chemicals in the world today, with 13 million tons produced annually in the United States alone. And although there are alternative treatment methods, the majority of water systems still use some form of chlorine for disinfection because it offers an affordable and well understood means of eliminating waterborne diseases. In fact, filtration of drinking water plus the use of chlorine has been called one of the most significant public health advancements of the 20th century.

Yet every treatment technology has its risks, and it is critical to understand the dangers. That is why your employee safety training programs are so important. Here are some supplemental chlorine safety resources from our document library to help support an active chlorine safety/emergency response program at your plant.

• How to Handle Chlorine Gas Safely from Washington State Department of Health
• Ammonium Hydroxide and Sodium Hypochlorite Storage & Handling Issues from Florida Rural Water

Responding to Cold Weather Main Breaks

Recent extreme cold weather has affected a large numbers of private and public water lines across the country, resulting in low pressure, main breaks and water service disruptions, including this one at New York's JFK airport.  During the cold snap over the 2018 New Year's holiday, the St. Louis region alone had to deal with 60 breaks per day, with more than 40 crews out at a time. 

Responding to these events, both the dramatic and the more "invisible" ones, can be particularly challenging and can put utility staff at risk. Here are some resources that can help when frigid weather causes trouble: 

• USEPA's Extreme Cold and Winter Storms Incident Action Checklist
• Alaska Department of Environmental Conservation's Intro to Small System Systems chapter five section on methods for thawing out frozen water lines (p. 181).
• Of course, prevention is the best cure, so here is Indiana AWWA's updated winterizing checklist for ideas on how to prepare for freezing temperatures, snow, ice and sleet at your utility and around town the next time around. For even more readiness tips, take a look at this article on how to make water infrastructure winter-ready. 

Need a good public education tool to explain the water main break repair process to the general public? Check out this video from the city of Midland, Michigan showing how water distribution crews handle main breaks during the cold winter months. And here is another example from the city of Arlington, VA.

Common Treatment Deficiencies

This article was first published in the Summer 2012 issue of Spigot News, the Ohio EPA's drinking water program newsletter. Many thanks for allowing us to republish it! You may also be interested in the article Common Source Water Deficiencies.

Ohio EPA conducts sanitary surveys at least once every three years at community public water systems (PWS) and once every five years at non-community PWSs. The purpose of a sanitary survey is to evaluate and document the capability of a water system’s source, treatment, storage, distribution, operation and maintenance, and management. Each of these may favorably or adversely impact the ability of the system to reliably produce and distribute water that meets drinking water standards. 

This article is the second installment in a series of articles to help small water systems identify the most common problems found during a sanitary survey or other investigatory site visit conducted by Ohio EPA staff. The first article focused on source water (well) deficiencies. This article will focus on some of the more common treatment equipment deficiencies which are found during inspections of small water systems.  Future articles in this series will cover distribution deficiencies and other topics. 

Backwash discharge lines: If you have a softener or a pressure filter, you backwash your equipment to clean and replenish the media. The waste that is produced when you backwash discharges into a floor drain or another pipe, which carries the waste to where it will be treated.  If the pipe carrying the backwash wastewater from your treatment equipment is too close to, or even inserted into, the drain or pipe that carries the waste to treatment (see Figure 1), you could end up with back-siphonage.

This could occur if the pipe carrying the waste to treatment backs up and the wastewater is siphoned back into your drinking water treatment equipment, contaminating your treatment equipment with whatever waste the pipe is carrying. Solution: Ensure there is a sufficient air gap between the backwash waste pipe and the floor drain or the pipe conveying the waste to treatment to prevent backsiphonage (see Figure 2). 

Softener tanks, cover, and salt: Softener brine tanks should be kept in sanitary condition. The brine solution should be kept free of dirt and insects. Solution: The best way to accomplish this is to completely cover the brine tanks with an appropriately fitting lid. The lid should not be over- or under-sized and should be kept in place on top of the tank. Also, the brine tank should not be overfilled such that the lid does not fit snug on the tank (see Figure 3).

All substances, including salt, added to the drinking water in a public water system must conform to standards of the “American National Standards Institute/National Sanitation Foundation” (ANSI/NSF).  This is to ensure it is a quality product that will not introduce contaminants into the drinking water. Solution: Ensure the ANSI or NSF symbol can be located on the bags of salt you use or ensure your salt supplier can provide you with documentation from the salt manufacturer that it is ANSI or NSF certified. 

Cartridge filters: Over time, cartridge filters will become clogged with iron or other minerals from your source water. When clogged, the filters become a breeding ground for bacteria. Solution: Ensure filters are replaced in accordance with the manufacturers’ specifications or even more often, depending on the quality of your source water.

General maintenance: Water treatment equipment should be accessible and cleaning solutions and other non-drinking water chemicals and materials should be kept away from the equipment. If treatment equipment is not accessible for Ohio EPA staff to inspect during a sanitary survey, it will not be accessible to the water treatment operator for routine maintenance or during an emergency. Likewise, non-drinking water chemicals stored in close proximity to treatment equipment can be an invitation for a mix-up or, even worse, intentional vandalism (see Figure 4). Solution: Keep clutter and non-drinking water chemicals and equipment away from drinking water treatment equipment. Preferably, these items should be stored in a different room.

Common Source Water Deficiencies

This article was first published in the Winter 2011 issue of Spigot News, the Ohio EPA's drinking water program newsletter. Many thanks for allowing us to republish it!

Ohio EPA conducts sanitary surveys once every three years at community public water systems (PWSs) and once every five years at noncommunity PWSs. The purpose of a sanitary survey is to evaluate and document the capability of a water system’s source, treatment, storage, distribution, operation and maintenance, and management; these all may adversely impact the ability of the system to reliably produce and distribute water that meets drinking water standards.  

This article covers the sanitary survey or other investigatory site visits conducted at the water source and concentrates on the most common deficiencies found during the visit of small PWSs. Even though the article focuses on small systems, similar deficiencies can be found at larger public water systems. Future articles will cover treatment, distribution and other topics. 

There are common deficiencies surveyors hope not to find when conducting a sanitary survey, or when following up on complaint investigations or responding to total coliform bacteria positive sample results. Figures 1 and 2 show poor water sources and figure 3 shows an acceptable water source. Figure 1 shows a well equipped with a sanitary seal which is missing bolts. It also shows that the casing is flush or in line with the finished grade, and the electrical wire and raw water line are exposed and unprotected. Although the well is vented, it does not have a screened vent. The well is also not protected from surface water runoff, other contaminants or critters. 

Figure 2 shows a public water system well located in a parking lot. The well cap is missing bolts and therefore is not properly secured to the top of the well casing. There is also a depression surrounding the casing. If rainwater pools near the well, it can seep down along the casing and negatively impact the ground water and its quality. Located to the left of the well are bags of sodium chloride, which increases the potential for rust at the base of the well. Also, there is not enough protection around the well to prevent damage from motorized vehicles to the casing or electrical conduit.  

Although you can’t see this in the picture, the well has a 1988 approved “National Sanitation Foundation” (NSF) well cap but it is not a “Water System Council” PAS-97 (or Pitless Adapter Standard, 1997) approved cap as required. The PAS-97 cap provides a properly screened vent which is not present in this cap. 

Figure 3 shows an acceptable water source. The well casing extends approximately 24 inches above finished grade, which is beyond what is required (at least 12 inches above finished grade). The finished grade is sloped to drain surface water away from the well.  The approved well cap fits flush over the top of the casing and electrical conduit; it provides a tight seal against the casing and prevents the entrance of water, dirt, animals, insects or other foreign matter. The well is also properly protected with concrete filled posts to protect it from motorized vehicles and mowers.
