Frequently Asked Questions (FAQs)

Scope of 1910.1200
The GHS Guidelines


More than 30 million workers are potentially exposed to one or more chemical hazards in the workplace. There are an estimated 650,000 existing hazardous chemical products and hundreds of new ones are being introduced annually. This poses a serious challenge for employers as well as a health and safety hazard for exposed employees.

Because of the seriousness of these safety and health problems, and because many employers and employees know little or nothing about them, OSHA issued the original Hazard Communication Standard (HCS) in 1994. The basic goal of the standard is to be sure employers and employees know about work hazards and how to protect themselves; this should help to reduce the incidence of chemical source illness and injuries. As you can see below, Hazard Communication is close to the top of OSHA's Top Ten Cited Standards and is consistently at or near the top each year.

OSHA's Top 10

The following were the top 10 most frequently cited standards by Federal OSHA in fiscal year 2016:

  1. Fall protection
  2. Hazard communication
  3. Scaffolding
  4. Respiratory protection
  5. Control of hazardous energy (lockout/tagout)
  6. Powered industrial trucks
  7. Ladders, construction
  8. Machine guarding (machines, general requirements, general industry)
  9. Electrical, wiring methods, components and equipment
  10. Electrical systems design, general requirements

In March 2012, the Occupational Safety and Health Administration (OSHA) revised its Hazard Communication Standard to align it with the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS).

This course will discuss OSHA's 2012 Hazard Communication Standard and how employees can protect themselves from the dangers of hazardous chemicals in their work environment.

Course 105 Final Exam

Exam score sheet

After studying the course material and answering the quiz questions, it is time to take the final exam. We highly recommend answering the module quiz questions to check your understanding of the course material. The final exam questions are typically developed from these quiz questions.

OSHAcademy course final exams are designed to make sure students have gained a sufficient understanding of the content covered within each course. To help demonstrate this understanding, students must achieve a passing score on course final exams. It is OSHAcademy's policy to protect the integrity of our exams: as a result, we do not provide missed questions to students.

This is an open book exam. Students are permitted to use a separate browser window to review course content while taking the exam. If you do not pass a final exam, you will see a "Retake Exam" button next to the course on your student dashboard.

If you have already paid for your certificate

If you have already paid for certificates, your exam score will be displayed on your student dashboard after successfully passing the final exam. If you chose PDF certificates, you can view and print your certificate and personal transcript from your student dashboard. If you chose original printed documents, they will be prepared and mailed to the address in your student account.
