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.

Sewage Lagoon Basics

A sewage lagoon is a large pond into which the sewage or effluent from the sewage system flows. Sewage lagoons are also called effluent ponds
 
The sewage and effluent are broken down by germs in the lagoon. The sun and wind play an important role in the working of the lagoon. They provide light, warmth and oxygen to the water. This is necessary for the growth of bacteria in the water. 
 
The light, warmth and oxygen also aid the growth of algae in the water. Algae give the lagoon its greenish color. Algae helps the bacteria break down sewage and effluent. 
 
The wind helps with the evaporation of the water and serves to get oxygen into the water. It also creates waves which help stop insects from breeding and living in the water. Disease-causing mosquitoes, for example, need still water to breed. 
 
For a lagoon to be able to break down the sewage or effluent properly and to be a healthy place it must meet the following requirements: 

  • It must not be more than 1 meter deep 

  • The banks need to be sloped at approximately 15 to 20 degrees and made of concrete, gravel or rock. This stops the wave action from eroding (breaking down) the banks 

  • There must be no grass, trees or other vegetation on the banks or surrounding area which would stop the sun and wind action needed by the lagoon 

  • The water must be free of vegetation or objects which stop the lagoon's surface wave action or create still patches 

  • It must be surrounded by a high fence with a lockable gate to keep children and animals out 

Lagoon overflows 

Where there is only one lagoon in the sewage disposal system, it will have an overflow situated directly opposite where the pipe carrying the sewage or effluent enters the lagoon. If there is more than one lagoon in the system, the overflow will be in the last lagoon. 
 
The overflow releases water from the lagoon system which has not been removed by evaporation. New lagoon systems are required to be designed so disposal occurs by evaporation only. They should not rely on overflow, except during very heavy rainfall periods. However, where an existing lagoon system uses an overflow method, the overflow should not create a flooded or swampy area suitable for mosquito breeding, or where it may contaminate drinking water or the environment. 
 
Lagoon maintenance 

Lagoons which are not working properly or are poorly maintained or damaged may be dangerous to health.  Signs of a lagoon which is not working properly are heavy overflow, mosquito breeding or a bad smell. 
 
Signs of a lagoon which is poorly maintained or damaged include broken fences and gates, trees, shrubs or grass on the banks, grass growing and other objects in the water causing still patches. 
 
Unsafe sewage lagoon 
To be properly maintained the lagoon should be checked frequently and any problems reported to the authority responsible for providing maintenance. It is important to report any of the following: 

  • eroded or broken lagoon banks 

  • lagoon banks which are not angled at 15-20 degrees 

  • trees and/or other vegetation growing in the lagoon, on its banks or in the area around the lagoon 

  • bad smells given off by the lagoon 

  • water which is not a light, flecked green color 

  • still areas on the surface of the lagoon 

  • signs of mosquitoes breeding in the water 

  • damaged fences or gates that cannot be locked properly to keep out animals and children 

  • rubbish in the water 

  • a swampy situation near the lagoon (possibly caused by the overflow) which could provide mosquito breeding areas 

  • grass on the banks of lagoons, particularly growing at the edge of water, which can provide ideal mosquito breeding areas
