Is Hazwoper Training Required? (Who Are exempted)

Is HAZWOPER training required?

Yes, HAZWOPER (Hazardous Waste Operations and Emergency Response) training is required in certain technical and specific circumstances, as outlined by the Occupational Safety and Health Administration (OSHA) under 29 CFR 1910.120. This regulation applies to five distinct groups of employers and employees who are engaged in operations involving hazardous substances. Here’s a detailed breakdown:

  1. Cleanup Operations (§1910.120(a)(1)(i)):
    • Required for employees involved in cleanups at uncontrolled hazardous waste sites, as defined by the Environmental Protection Agency (EPA).
    • These sites are typically listed on the EPA’s National Priorities List (NPL), state priority site lists, or sites recommended for the EPA’s Superfund program.
  2. Corrective Actions Involving Clean-Up Operations (§1910.120(a)(1)(ii)):
    • Applies to operations under the Resource Conservation and Recovery Act (RCRA) where corrective actions involve cleanup activities.
    • Technical specifications include sites where hazardous wastes are treated, stored, or disposed of and are subject to RCRA corrective action regulations.
  3. Voluntary Cleanup Operations (§1910.120(a)(1)(iii)):
    • Refers to operations at sites recognized by federal, state, local, or other governmental bodies as uncontrolled hazardous waste sites.
    • Technical criteria involve sites where cleanup occurs without enforcement by government agencies.
  4. Operations Involving Hazardous Wastes at Treatment, Storage, and Disposal (TSD) Facilities (§1910.120(a)(1)(iv)):
    • Required for employees working at facilities subject to the RCRA.
    • Technical focus is on the management and handling of hazardous wastes at TSD facilities.
  5. Emergency Response Operations for Releases of, or Substantial Threats of Releases of, Hazardous Substances (§1910.120(a)(1)(v)):
    • Mandatory for employees responding to emergencies involving hazardous substances.
    • Technical aspects include the size and complexity of the operation, the nature of the hazardous substance, and the likelihood of high-level exposure or catastrophic events.

Training Specifications and Hours:

  • General Site Workers (e.g., equipment operators, general laborers): 40 hours of off-site training and three days of actual field experience under direct supervision.
  • Occasional Site Workers (e.g., groundwater monitoring, land surveying): 24 hours of off-site training and one day of actual field experience.
  • TSD Facility Employees: 24 hours of initial training and eight hours of refresher training annually.
  • Emergency Response Personnel: Varies depending on role and responsibility. Ranges from first responder awareness level (minimum of four hours) to hazardous materials technician level (24 hours of training).

The training is technically required for employees who are engaged in operations involving hazardous wastes or emergency response to hazardous substance releases, with specific training hours and types of training varying based on the nature and risk level of the work involved.

You Must Also Understand That Annual Refresher Training is Required

Yes, the refresher training is required annually. What does the term “annual” mean in the standard? To answer this, let us reference the March 7, 2007 letter from K. Gottsleben to OSHA and answered by the MOSH Compliance Unit of the Department. It says:

Question: What is OSHA’s stance on the term “annual”? Does this mean a period of twelve months, simply completing the course in consecutive calendar years, or just enrolling in HAZWOPER refresher training when the need to visit a TSD facility arises?”

Response: First, it is important to clarify that references in your letter to training requirements in 1910.120(e) are not appropriate for operations conducted at TSD facilities regulated under the Resource Conservation and Recovery Act of 1976 (RCRA). The training requirements of 1910.120(e) are specifically directed at employees involved in hazardous waste site clean-up operations or corrective actions, such as those conducted at EPA National Priority List sites, state prioritylist sites, or RCRA corrective action sites.

Here’s a detailed look at the annual refresher training requirement:

  1. Mandatory Annual Training:
    • OSHA mandates that all workers who have completed the initial HAZWOPER training (whether it’s the 40-hour, 24-hour, or any other specialized training) must undergo an 8-hour refresher course annually.
    • This is to ensure that their knowledge and skills are up-to-date with the latest safety practices, regulatory changes, and technological advancements.
  2. Content of Refresher Training:
    • The certification you gained from the initial training does last for 12 months. You need to take a refresher to stay compliant. The refresher training typically revisits key elements of the initial training, such as personal protective equipment (PPE) use, decontamination procedures, and emergency response.
    • It also introduces new information and changes in regulations, safety practices, and technological tools.
  3. Documentation and Compliance:
    • Employers are required to maintain records of all HAZWOPER training, including the annual refreshers. This documentation should include the date of the training, the contents covered, and the names and qualifications of the instructors.
    • Failure to comply with the annual refresher training requirement can lead to regulatory penalties and increased risk of workplace incidents.
  4. Importance Beyond Compliance:
    • Beyond meeting regulatory requirements, the annual refresher course is crucial for reinforcing safety practices and enhancing the overall safety culture within an organization.
    • Regular training updates help in addressing evolving workplace hazards and ensure that employees are prepared to respond effectively in emergency situations.
  5. Customization and Relevance:
    • While the refresher training is standardized in terms of duration, the content can be tailored to address the specific hazards and operations of a particular workplace.
    • Employers often use this opportunity to review and discuss site-specific safety issues, recent incidents, or near misses, and focus on areas needing improvement.

The annual refresher training is a vital component of ongoing safety education and compliance. It plays a critical role in keeping workers informed, skilled, and prepared to handle hazardous materials safely, thereby protecting both their health and the environment.

Understanding Training Regulations

When you delve into OSHA’s HAZWOPER standards, detailed in 29 CFR 1910.120, you’re not just flipping through a dry manual; you’re taking the first step in safeguarding your health and career in industries that deal with hazardous waste. These regulations are meticulously designed to ensure your safety in workplaces that could be fraught with chemical, biological, and physical hazards.

Let’s break it down: If you’re working on a site with potential exposure to hazardous substances, OSHA requires that you undergo comprehensive training. The depth of training you need directly correlates with the level of risk in your job. For instance, if you’re on the front lines, dealing with the immediate hazards of chemical spills or waste disposal, you’re looking at a mandatory 40-hour training that equips you to don the necessary personal protective equipment (PPE), handle emergencies, and understand decontamination procedures.

But it’s not just the on-site workers who need to be aware. If you’re a manager or supervisor, you need the same level of training as the workers you oversee, along with additional coursework to manage site activities effectively.

Now, what happens if you sidestep these regulations? Case studies show that non-compliance can lead to severe consequences. Companies have faced hefty fines, and individuals have seen their careers derailed. One notable case involved a cleanup operation where workers were not provided with the proper training, leading to significant fines for the company and an OSHA mandate for immediate compliance training.

Remember, these regulations aren’t just bureaucratic hoops to jump through. They are vital measures that keep you informed, prepared, and safe. So, when you’re considering whether to prioritize this training, think of it as an investment in your professional future and personal well-being. After all, in a field where risks are inherent, your knowledge and preparation are the keys to a safe and successful career.

Aside from OSHA, state-specific requirements should be adhered to as well.

State-Specific Requirements

If you’re trying to determine the scope of the training requirements for your workplace, it’s essential to know whether you’re operating in a state with an OSHA-approved State Plan or under federal OSHA jurisdiction. Here’s how it breaks down:

States with OSHA-approved State Plans Covering Both Private and State/Local Government Workplaces: In these states, the state plan is OSHA-approved and applies to all workplaces. The state’s standards must be at least as effective as federal OSHA standards, but they may have stricter or additional requirements. Examples of such states include California, Michigan, Virginia, and Washington. If you’re working in one of these states, you need to follow the state’s specific training requirements.

States with OSHA-approved State Plans Covering State/Local Government Workers Only: Some states have OSHA-approved plans that do not cover private-sector employees but do cover state and local government workers. This means that private employers in these states are still under federal OSHA jurisdiction. States like Illinois, Maine, New Jersey, and New York fall into this category. If you’re a state or local government worker in these states, you’re subject to state-level HAZWOPER standards, whereas private sector workers must adhere to federal OSHA regulations.

Federal OSHA States: Finally, there are states where federal OSHA directly oversees all workplace safety regulations, as there is no OSHA-approved state plan in place. In these states, both private sector and state/local government workplaces must comply with federal HAZWOPER training requirements. Examples include Florida, Georgia, and Ohio.

Understanding whether your state operates under its own plan or under federal OSHA is crucial for compliance. You can typically find this information on the OSHA website or by contacting your state’s labor department directly. It’s important for you to ensure that your training meets the appropriate standards for your state to maintain workplace safety and legal compliance.
