Silica Dust Collection in manufacturing
Tough Regulation? Challenge Accepted.
In mid-2018, the Occupational Health & Safety Administration (OSHA) set into place the most stringent silica dust collection regulations to date. If your manufacturing process involves handling or cutting products made with sand, you know what it takes to cut permissible exposure limits, or PELs, of respirable crystalline silica in half. The standard requires manufacturers to essentially eliminate the harmful particulate from your facility 鈥� a target that鈥檚 not easy to meet.
That鈥檚 where 淫乱社区 comes in. If you need help with OSHA silica compliance, our highly skilled team is proficient in designing silica dust collection systems that help manufacturers meet the regulation. Let鈥檚 accept this challenge, together.
The OSHA Silica Standard, Explained
OSHA鈥檚 silica standard helps keep workers safe, protecting them from extended exposure to respirable crystalline silica and increased risks of lung disease. When explaining the rigor of OSHA鈥檚 standard, we like to put it in a perspective that can be surprising.
Here are a few facts about the OSHA standard:
The 鈥渞espirable鈥� in respirable crystalline silica refers to the portion of the particulate that makes it past the unciliated part of the lungs, meaning our bodies don鈥檛 expel it.
That part of the dust has a median aerodynamic diameter of four microns. In comparison, a human hair鈥檚 diameter is somewhere between 50 and 70 microns.
The amount of respirable crystalline silica now allowed in a manufacturing facility is tiny鈥�50 micrograms per cubic meter of air, averaged over an eight-hour day.
Let’s put this silica amount into perspective: You know those white sugar packets you get in restaurants? If one was filled with respirable crystalline silica, it wouldn’t meet the standard for a facility the size of a football field.
Meeting the Silica Standard
If your process includes products that contain respirable crystalline silica you first need to meet environmental controls. If those controls don鈥檛 help you meet the standard, your employees exposed to silica need to wear respirators. We can install a silica dust collection system that brings you into compliance. We鈥檝e helped bring manufacturers into compliance with baghouse dust collectors or entire systems in various industries:
Foundries
Glass
Pottery and ceramics
Concrete
Stone
Shingle
Sand plants
Mining
If you鈥檙e unsure about how much silica dust is in your facility, the first step is to hire an industrial hygienist to take samples. The sampling is required for every employee in every area of your plant for every shift. Once the sampling is done, you鈥檒l be armed with the information you need to determine next steps.
OSHA Silica Standard Meets Our Dust Collection Design
If sampling has shown you鈥檙e not in compliance or you know you鈥檙e not meeting the regulation, we can help in designing, building and installing a dust collection system. Here鈥檚 how we start the silica dust collection process:
- Using sampling from the industrial hygienist, we determine where the silica is being generated in your plant so we can help you effectively capture it.
- For a new system, we may use our engineering software to visualize your silica generation points and particulate size to determine the capture velocity needed.
- We will recommend dust capture design and improvements.
- We design baghouses, ductwork and hoods that meet your system鈥檚 operating parameters.
- A complete silica dust collection system build and installation helps you eliminate exposure to hazardous particulates and reduces your housekeeping.
How Makeup Air Systems Can Help
Silica exposure can worsen without a makeup air system. As air is removed from your plant through the ventilation system, that air needs to be replaced. If you don鈥檛 have a makeup air system, fresh air will find its way in鈥攖hrough cracks or doors. As these drafts combine with particulate on your floors and equipment, silica exposure may increase. At 淫乱社区, we鈥檝e seen the benefits of a makeup air system firsthand and can design one to match your needs.
Our Promise
What we design will be based on your manufacturing process, particulate and facility size. When it comes to helping you be compliant, we don鈥檛 believe in one size fits all. There is no doubt鈥攖he standard is tough. But, with 淫乱社区鈥檚 highly trained design team on your side, you can meet it.
