How long is silica training?
|DURATION:||Approximately 45 mins – 1 hour|
|REGULATIONS SATISFIED:||Meets the requirements for OSHA’s new Silica in Construction standard found in 29 CFR 1926.1153. *Employers, supervisors, or competent Persons should take our Silica in Construction for Employers or Competent Persons course #1301|
What is silica awareness training?
Workplace exposures to crystalline silica can cause serious health problems, including lung cancer and other chronic illnesses. In this course, you will learn about the potential risks of inhaling silica dust, how to prevent exposures and how to respond if an exposure occurs.
How much dust do you need to inhale to get silicosis?
Because silicosis is caused by cumulative or repeated exposure to respirable crystalline silica, it makes sense that we would want to limit exposure as much as possible! OSHA has set the Personal Exposure Limit (PEL) at 50 micrograms per cubic meter of air, averaged over an 8 hour shift.
Is silica dust hazardous?
Exposure to respirable crystalline silica dust during construction activities can cause serious or fatal respiratory disease. Employers and workers can take several steps to reduce exposures and lower risks.
How often is silica training required?
While there is no annual refresher training requirement, additional training must be provided as often as necessary to ensure that workers know and understand respirable crystalline silica hazards and the protections available in their workplace.
Can you get silicosis one exposure?
Silicosis usually develops after being exposed to silica for 10-20 years, although it can sometimes develop after 5-10 years of exposure. Occasionally, it can occur after only a few months of very heavy exposure.
How do I protect myself from silica dust?
Water can keep silica dust out of the air – and out of your lungs. Use tools with water attachments to control dust at the source. Water can also keep dust down during activities like sweeping and demolition. Use tools with vacuum attachments to capture the dust right where it starts.
How long does silica dust stay in the air?
This form of dust is so small that it can stay in the air for up to 12 days. Sometimes when we don’t see dust, there are still particles circulating about!
Can the lungs remove silica dust?
Crystalline silica is hazardous to health Repeated exposure to high levels of these fine crystalline silica particles can cause a variety of diseases that mostly affect the respiratory system. Our lungs have ways to remove some of the dust we breathe in, such as coughing or bringing up phlegm.
Does silica stay in your lungs forever?
Silica dust is very fine, much smaller than a tiny grain of sand found on a beach. Crystalline silica is a designated known human carcinogen meaning it is a definite cause of cancer in humans. Once you breathe it in it can go deep into your lungs and stay there – permanently scarring and damaging the lung tissue.
Can lungs heal from silica?
When silica dust enters the lungs, it causes the formation of scar tissue, which makes it difficult for the lungs to take in oxygen. There is no cure for silicosis.
Does concrete have silica in it?
Crystalline silica is found in materials such as concrete, masonry and rock. materials, there are numerous ways for construction workers to be exposed. SOME ACTIVITIES IN WHICH SILICA DUST MAY BE PRESENT IN THE AIR INCLUDE: TT 1 Abrasive blasting using silica sand as the abrasive.
What you should know about silica dust?
Silica dust is very fine, much smaller than a tiny grain of sand found on a beach. This is what makes it so easy to inhale. If you look at the full stop at the end of the previous sentence, that is around 200-300 micrometres in diameter. Whereas the respirable crystalline silica particle is only 5 micrometres in size.
What is silica and why is it dangerous?
Silica also acts as a diuretic, which can be dangerous for anyone taking a “water pill.” Taking both together can lead to dehydration from the excessive water loss in the body, which can also cause electrolyte imbalance. Potassium is typically the most affected by this situation, as levels become very low.
Which vacuum should I use for silica dust?
Using an Industrial HEPA Vacuum for Silica Dust Control and OSHA Compliance. High Efficiency Particulate Air (HEPA) filters, which describes filters that are capable of trapping 99.97 percent of particles that are larger than 0.3 microns, can contain and eliminate even the most hazardous materials found on earth. Industrial vacuums with true HEPA filtration are chosen by workers across the globe for battling silica dust on their job sites.
What kind of Mask do I need for silica dust?
Professional contractors may need respirators for more high-risk jobs that include handling chemicals or hazardous materials like lead paint and asbestos. Paper dust masks are designed to reduce exposure to solid particles like dirt, silica and pollen.
