Understanding Crystalline Silica Dust Exposure Control
What is silica dust and why is HEPA filtration so important?
Cyrstalline Silica dust comes in three forms; cristobalite, tridymite and the most commonly known is quartz. Silica dust is an ongoing problem at construction sites that is causing a number of illness’ and diseases that are potentially fatal. The deadly dust is created at construction sites by drilling, grinding, cutting, and blasting materials containing silica particles that are invisible to the human eye. Is your industry affected?
According to OSHA the main industries affected include:
- Glass manufacturing
- Structural clay
- Dental laboratories
- Paintings and coatings
- Jewelry production
- Ready-mix concrete
- Cut stone and stone products
- Abrasive blasting in:Refractory furnace installation and repair
- Maritime work
- General industry
- Hydraulic fracturing for gas and oil
- Asphalt products manufacturing
How do you help in limiting exposure to a deadly dust that is microscopic?
There are a number of work practices to use in controlling crystalline silica dust:
- Watering down areas before you dry sweep
- Dry sweeping with a HEPA compliant *industrial sweeper machine*
- Using local exhaust ventilation (indoors)
- Floor Scrubbing with regulation *industrial floor scrubbers* that use heavy water flow (water flooding)
- Using the manufacturers water rate recommendation for water tools (*scrubbers, scrubber/sweepers*)
- Using certain *floor scrubber and sweeper solutions* offer facilities dust control tools that meet OSHA requirements.
Now companies are faced with new challenges as a result of this deadly dust. Maintaining a healthy work environment, complying with OSHA regulation, and maintaining good air quality are some of the challenges that their facilities are now facing today. Utilizing the technological advances of modern floor cleaning equipment and solutions can help maintain air quality and mitigate respirable silica dust.
OSHA Compliant Industrial Scrubbers and Sweepers
In complying with OSHA Permissible Exposure Level standards, PowerBoss created a 5 step dust control filtration system:
The PowerBoss filtration system will create a healthier and cleaner work environment while maintaining your facilities OSHA compliance.
PowerBoss Machines with OSHA compliant options:
- Atlas Sweeper
- Armadillo Sweeper 6x
- Armadillo Sweeper 9x
- Armadillo Sweeper 10x
- Admiral 32 XL Sweeper Scrubber
- Nautilus/ Nautilus Hi Dump Sweeper/ Scrubber
- Commander T82 Sweeper/Scrubber
Tennant machines also offer OSHA compliancy with some HEPA filtration options:
- Continuous water spray helps moisten side brushes and control silica dust. This keeps the silica dust wet until the scrubbers remove the dust from the surface.
- Using water to eliminate dust from becoming airborne the scrubber is then able to pick up the wet dust eliminating exposure.
HEPA Filtrated Sweepers
- In addition to Tennant’s current filtration system an additional HEPA filter has been added for providing superior filtration of 99.97% to 0.3 microns.
Tennant Machines with OSHA compliant options:
- Tennant T20 Rider Scrubber
- Tennant T17 Rider Scrubber
- Tennant T16 Rider Scrubber
- Tennant T12 rider Scrubber
- Tennant T7- Rider Scrubber
- Tennant 5700-Walk- Behind Scrubber
- Tennant 5680- Walk-Behind Scrubber
- Tennant T2-Walk- Behind Scrubber
- Tennant T1- Walk- Behind Scrubber
- Tennant S30- Rider Sweeper
- Tennant S20- Rider Sweeper
- Tennant 6100-Rider Sweeper
- Tennant S10 Walk- Behind Sweeper
Create a healthy plan and have peace of mind about your upcoming OSHA inspection. Let the machines do all of the work and keep your facility free of deadly silica dust. By implicating this new rule OSHA hopes to save over 600 lives out of the 2 million workers that are exposed to silica dust on a regular work day. Click here to see the Final Rule.
