Welcome!

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.

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

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 29 CFR 1926.1153, Respirable crystalline silica. Additional information on OSHA’s silica standard can be found at OSHA's Silica Webpage.

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.
