Safety guides and audits to make your job as a safety professional easier

Welcome!

Hi, and welcome to the course. If you are a safety manager, supervisor, committee member, or someone who is entering into the occupational safety and health field, this course will help you understand your important responsibilities.

Here's how it works (Read this... it's important!)

  1. Study each course module. Just click on the course "Modules" tab above to get started. It takes about 30 minutes to one hour to complete each module, including the quiz.
  2. Complete each module quiz. Each quiz is 5 questions. When you submit the quiz, a new web page will load with instant feedback on your answers. After you complete the quiz, start on the next module. There is no need to wait! No hurry either. You are in control of the pace of learning.
  3. If you have questions as you study, just send us an email.

    Frame not included.
  4. Order an Optional Certificate. If you want certification of your training, order a high quality certificate. Our training is free. We only charge a small fee to provide documentation of your training. If you are enrolled in one of our professional safety and health programs, you can save money by purchasing the program package that fits your needs. If you just want to purchase the certificate for this course, a link will be provided on your student dashboard after you pass the final exam. Just click on the "Purchase Certificate" Link.

    For individual courses, the PDF certificate is only $, the original certificate is $ (shipping extra), and the PDF & original certificate is $ (shipping extra).
  5. Complete and submit the final course exam.
    • Final exams consist of 25 questions.
    • To meet OSHA requirements, you must pass the final exam with at least a 70% score.
    • If you do not pass the exam, you may retake the exam.
    • If you pass the exam, you may not retake the exam just to raise your score.
    • Most final exam questions are derived from module quizzes.

OK, Let's go!

Have fun and study hard. To start, just click on "Introduction" above.

Course Introduction

Stop Silicosis - DOL

Crystalline silica commonly occurs in nature as the mineral quartz. It is found in granite, sandstone, quartzite, various other rocks, and sand. Workers who inhale very small crystalline silica particles are at risk for silicosis – an incurable, progressively disabling and sometimes fatal lung disease.

About 2.3 million workers are exposed to respirable crystalline silica in their workplaces. About two million construction workers are exposed to respirable crystalline silica in more than 600,000 workplaces. OSHA estimates more than 840,000 of these workers are exposed to silica levels that exceed the permissible exposure limit (PEL).

OSHA has finalized a new rule for respirable crystalline silica, effective as of June 23, 2016, and construction companies will have one year to comply with the provision of the new rule.

Key provision of the rules include:

  • Reduces the permissible exposure limit (PEL) for respirable crystalline silica to 50 micrograms per cubic meter of air, averaged over an 8-hour shift.
  • Requires employers to:
    • use engineering controls (such as water or ventilation) to limit worker exposure to the PEL;
    • provide respirators when engineering controls cannot adequately limit exposure;
    • limit worker access to high exposure areas;
    • develop a written exposure control plan;
    • offer medical exams to highly exposed workers; and
    • train workers on silica risks and how to limit exposures.
  • Provides medical exams to monitor highly exposed workers and gives them information about their lung health.
  • Provides flexibility to help employers — especially small businesses — protect workers from silica exposure.

In this course, we’ll discuss these new provisions with special emphasis on effective control measures eliminate or reduce exposure to safe levels.

Course 851 Final Exam

OSHAcademy course final exams are designed to help ensure students demonstrate a sufficient understanding of the content covered within each course. To help demonstrate this understanding, students must achieve a minimum score of 70% on final exams. It is OSHAcademy's policy to protect the integrity of our exams and, as a result, we do not provide missed questions to students.

After you have studied all of the course material and taken the module quizzes, you can take the final exam. The module quizzes are optional, but we highly recommend you take each quiz, as the questions are similar to those on the final exam.

This is an open book exam. As you are taking the exam, if you find a question you are unsure of, you should use the course study guide or course web pages to research the correct answer. Don't worry if you fail the exam. You can study and retake the exam when you are ready.

If you have already paid for a Certificate Program

If you have already paid for your certificates, your exam score will be displayed in your student dashboard next to the course. You will also be able to view or print the course PDF certificate if you purchased this option. Your PDF transcript will also be automatically updated to include the course.

If you only want free training

You are welcome to take all of our courses for free! We only charge a fee if you want certificates, transcripts and exam scores to document your training. If you have not made a payment for your certificate, we will archive your exam results and you will see "Completed!" next to the course if you passed the exam. If you did not pass the exam with a score of 70% or higher, you will need to retake the exam.
