It is essential for workers involved in the treatment, storage, and disposal of hazardous waste to be adequately trained. HAZWOPER training equips them with the knowledge and practice needed to perform their tasks safely and within legal requirements.  Also worth noting is that OSHA requires employers to provide Hazwoper Training to their employees before they are exposed to hazardous materials and operations.  The level of training can vary based on the potential risks and responsibilities associated with a specific role, and it’s not limited to those directly handling hazardous materials but also includes supervisors overseeing these operations. OSHA necessitates that these folks complete a form of HAZWOPER education suitable to their function and the possibility of exposure to dangerous substances.

Training Requirements

The specific requirements for this training depend on the level of involvement a worker has with hazardous waste operations. OSHA has established different training levels based on the tasks performed and the potential exposures faced.

The most comprehensive is the 40-hour version, designed for employees with duties that could involve a presence on a regulated hazardous waste operation site, or general site workers who may be exposed to hazardous substances. They must also complete three days of supervised field experience.

Supervisors and managers overseeing hazardous waste operations must complete a minimum of 24 hours of initial training. Additionally, 24 hours is intended for occasional site workers who may face hazardous substances but are unlikely to exceed permissible exposure limits. In addition to the 24 hours of training, these workers are also required to undergo one day of field supervision.

Furthermore, both general site workers and supervisors are required to complete an 8-hour annual refresher training to stay up-to-date on any changes in regulations or procedures.  This course reinforces key safety principles and updates the workers on any changes or developments in regulations or technologies.

Mandatory Topics and Hands-On Training

All HAZWOPER courses must cover a range of mandatory topics. These are stipulated by OSHA and include, but are not limited to:

  • Hazard recognition
  • Decontamination procedures
  • Personal protective equipment
  • Emergency response
  • Understanding of OSHA’s regulations

Hands-on training is a crucial component that complements the instructional aspect. It ensures that workers can perform tasks and use equipment effectively in a controlled environment before they encounter real hazards. OSHA stipulates that employers are required to ensure that employees receive HAZWOPER training from qualified trainers, which includes interactive practical exercises reflective of their work conditions.

Difference Between Hazwoper 40 and OSHA 30

HAZWOPER 40 and OSHA 30 are both critical training programs developed by OSHA but serve different purposes. Understanding the differences is essential for professionals seeking the right safety training credentials.

HAZWOPER 40 Training:

  • Aimed at workers involved in clean-up operationsemergency response, and storage, disposal, or treatment of hazardous substances, or who may otherwise be exposed to them.
  • Comprises 40 hours of training.
  • Involves at least three days of supervised field experience, on top of the initial 40 hour, which can be taken online.
  • Course content includes hazardous waste regulations, personal protective equipment (PPE), and decontamination procedures.

OSHA 30 Training:

  • Designed for supervisors and workers with some level of safety responsibility.
  • Provides 30 hours of instructional training focusing on workplace safety and health.
  • Curriculum covers a broad spectrum of topics that include fall protection, electrical safety, and accident investigation but is not limited to hazardous waste operations.

The main difference lies in the focus and application: HAZWOPER 40 is specifically for hazardous waste operations, requiring hands-on experience, while OSHA 30 provides more general safety training applicable across various industrial sectors. Folks should choose the course that matches up with their occupational roles and the specific safety needs of their industry.

Is Online Training Accepted?

Online training is a valid option for meeting OSHAs training requirements. It provides flexibility in terms of accessing coursework and completing modules at a learner’s own pace.

For HAZWOPER training, the following online options are recognized by OSHA:

  • 40-Hour HAZWOPER Training: Designed for workers involved in cleaning operations, voluntary clean-up operations, disposal, or emergency response operations involving hazardous substances.
  • 24-Hour HAZWOPER Training: Intended for workers with a lower risk of exposure to hazardous substances.
  • 8-Hour HAZWOPER Refresher Training: An annual requirement to maintain a certification obtained from the 40-hour or 24-hour training.

The efficacy of online training is contingent upon its ability to cover the necessary curriculum and meet the standards as outlined under 29 CFR Part 1910.120. Practical, hands-on experience is also essential—particularly for tasks such as donning and doffing of protective gear or using air monitoring equipment. So, it is often necessary to supplement online learning with on-site, hands-on instruction to ensure comprehensive skills mastery.  Many companies will do this during their new employee orientation, or when a new worker is brought on to a job site.  And many new workers will do the 40 or 24 hour training online, and receive the direct hands-on experience during initial job site or new hire orientation training.

OSHA mandates that certain components of HAZWOPER training are conducted through actual experience, affirming that employees receive the practical training required to perform their duties safely.
