For More Information

Do news stories of workplace incidents make you wonder if your company has its safety-related matters in order?

Imagine that someone in your workplace experienced an on-the-job injury tomorrow.

  • Do you know what to do when someone gets hurt?
  • Do you know what written programs you are required to have in place at all times?
  • Do you know what OSHA will ask when performing an on-site inspection?
  • Do you know what rights you have during an OSHA inspection?

Ask yourself…

  • Are you interested in enhancing your current safety knowledge or preparing yourself for opportunities in the safety and health field?
  • Would you like to learn how your company can save thousands of dollars every year just by making a few simple changes?
  • Would you like to learn how to lower fatalities, injury rates, near misses and OSHA citations in the workplace?
  • Would you like to learn how to identify and apply the OSHA regulations that apply to particular hazards in your workplace?
  • Are you interested in learning the true costs of an accident, including various hidden costs?
  • Do you want to learn why employees violate safety rules even when they know it’s not safe to do so?
  • Would you like to learn what it takes to set up an effective health & safety program, and how to present the information in a well‐received manner?
  • Would you like to learn more about OSHA requirements, inspections, citations, hazard recognition, how to read and understand OSHA’s federal regulations, and a ton of other safety information?

If so, then COSS is for you!

The University of Delaware’s Certified Occupational Safety Specialist® (COSS) course consists of 40 hours of hands-on, face-to-face instruction delivered by an Authorized OSHA Outreach Trainer in both construction and general industry. Case studies and workshops are used extensively, as well as guest speakers from OSHA and other governmental agencies. Student presentations, daily quizzes, practical reviews, and a comprehensive final exam will allow you to demonstrate your competency. Participants testify to the value of the training they receive; instead of simply “testing into the designation,” they feel like they worked hard to earn it.

Participants will learn how to read and understand the OSHA 1910 and 1926 Code of Federal Regulations and will be able to help their company avoid OSHA citations that cost millions of dollars. More importantly, by learning how to work safely on a job site, participants can teach their employees and coworkers how to eliminate the risk of fatalities and near misses. Almost 85% of COSS graduates responding to a survey indicated that since taking COSS, their company’s injury rate and/or OSHA recordables have decreased by as much as 25%, and others attest to as much as a 100% decrease!

The class also addresses the psychology of safety, the true cost of an accident, hazard recognition, how to start a health and safety program, behavior-based safety, and much more.

Upon completion of the course, a Certified Occupational Safety Specialist® will be able to:

  • Determine the true cost of an accident
  • Calculate Total Recordable Incident Rates
  • Search company and public records to assess where the greatest likelihood of an accident may lie
  • Master the use of CFR’s [both Construction and General Industry]
  • Identify hazards, determine regulatory requirements, implement corrective actions, and train personnel in changes that are required
  • Perform risk analyses for key jobs and processes
  • Perform accident investigations
  • Develop and implement a complete safety audits and inspections program
  • Prepare and present effective safety training presentations
  • Communicate corporate safety initiatives and goals
  • Develop, implement and maintain company safety plans and manuals
  • Be a competent person as regards to general safety by OSHA’s definition: “capable of identifying existing and predictable hazards…and who has authorization to take prompt corrective measures to eliminate them” [CFR 1926.32(f)]
