Remove Joint Sealant - Outperforms Hydro Blasting ~ Significantly Faster, Cleaner, Better.

Joint Sealant Cut-Out Blades:  4-1/2" ~ 12".The design of the Hybrid Hot Rod Saws was based on a project for a US Air Force Base in San Diego, CA.  The contractor was hydro blasting joint sealant from expansion joints on the runways.

Because of the environmental mess created from hydro blasting we were called in to demonstrate the Hot Rod Saw and our Stellite Cutter Blade.  Besides being dust and slurry free, the contractor realized a 3:1 increase in productivity vs. Hydro Blasting!

How about Your Vacuum?

Does your vacuum have enough CFM to handle your wheel's diameter?

OSHA's Silica Dust Exposure Law - Requires the following CFM Rating:  25 CFM or greater per inch of wheel diameter.  For example, a 6" blade needs 150 CFM (6" x 25 CFM).

 

Final Rule - CFM Requirements

To comply with OSHA's Silica Dust Exposure Law, one of your first steps is to select a vacuum or cyclone that has enough CFM to handle the diameter of the grinding or cutting wheel that you will be using.  Use the chart and information below to help you select the vacuum that will have enough CFM.

bullet

80 lbs. of silica dust are created in 8 hours when grinding brick mortar joints (1/4" wide x 1/2" deep)

bullet

On soft mortar, 110 lbs. of silica dust is created.

With a Dust Director Vacuum, with the filter system maintaining optimum suction, your productivity is only limited to the size of the collection tank (i.e. the smaller the tank the more times you'll stop to empty it, but you'll never have to stop to clean the filter).  Ideally, you'd like to grind brick mortar joints for at least half the day before you have to empty the tank.

KNOW THE RULE:

OSHA's Final Rule to Protect Workers from Exposure to Respirable Crystalline Silica

Rule requires engineering controls (tools and equipment) to keep workers from breathing silica dust.

What is Respirable Silica Dust?  These tiny particles (known as "respirable" particles) can penetrate deep into workers' lungs and cause silicosis, an incurable and sometimes fatal lung disease.  Crystalline silica exposure puts workers at risk for developing lung cancer and other possible debilitating respiratory diseases such as chronic obstructive pulmonary and kidney disease.

How Much Respirable Silica Dust is Safe to Breath?  OSHA has issued their Final Rule to curb these respirable and kidney diseases in America's work force by limiting a worker's exposure to respirable crystalline silica to 50 micrograms per cubic over an 8-hour shift.

Packet of sugar - example of 53 micrograms.What Does 50 Micrograms of Respirable Silica Dust Look Like?  A good example may be one of those small paper packets of sugar or artificial sweeteners found in restaurants.

When used to demonstrate the dust concentration inside a building, the size of a football field (100 yards x 53 yards x 14' high).  The weight of one of those little packets is 53 micrograms, which is slightly over the PEL (permissible exposure limit) for Silica Dust of 50 micrograms.

Such a fine dispersing of dust at this concentration would essentially be invisibility.  It is also enough to put the workers at risk by contaminating the work area --- the size of a football field x 14' high.         

 

OSHA_Photo_1.jpg (848150 bytes)OSHA's Respirable Silica Dust Law - Effective:  23 June 2016.  Since 1999, the Dust Director® has been involved with various organizations aimed at improving the health and safety on construction sites.  On a meeting, dated 23 April 2014, the Dust Director® was invited to participate in a discussion about OSHA's upcoming Silia Dust Standard.  Besides the representatives from OSHA, the following organizations were also present:

bullet

NIOSH

bullet

CPWR (Center for Construction Research and Training)

bullet

Various university research scientists and professors

bullet

Health and environmentalist

bullet

Mike Kassman, National Safety Coordinator for the International Masonry Institute (IMI)

bullet

Jerry Scarano, Vice President of the International Union of Bricklayers and Allied Craft Workers (BAC).

In past meetings, by the use of various air testing meters, NIOSH determined that the Permissible Exposure Limit (PEL) of a worker being exposed to silica dust should not be greater than 93.4.  [On record, NIOSH tested the Dust Director® System (dust control guard and vacuum), and determined the complete system "provided the greatest reduction of capturing silica dust at 94% than any other vacuum and dust guard that was tested.]

Currently, to simplify the understanding and importance of containing silica dust exposure, OSHA and all parties involved, have adopted the buzz phase of "visible dust," as their measurement of whether silica exposure is being sufficiently contained for both the workers and public.

 

OSHA_Photo_6.jpg (988907 bytes)CASE STUDY:  Dust Left to Fly from a Skyscraper ~ An interesting case study was provided by a Detroit contractor who was tuck pointing at a high rise office building in downtown Detroit, 35 floors above the sidewalks.  A summarization of his findings on silica dust exposure is as follows:

bullet

Two workers were tuck pointing an office building, 35 floors up, without the use of dust control

bullet

The thinking was, to leave the silica fly and let it disburse into the sky . . . that it wouldn't harm anyone or anything

bullet

As the safety coordinator for the company, he monitored the air quality of his workers

bullet

His air quality readings were as follows:
>  Employee "A" was working in air quality that measured 85 times over the NIOSH established PEL
>  Employee "B", working downstream from employee "A", was receiving a concentrated dose of dust as his air quality measured 135 times over the PEL!

While this case study shows how "visible dust" may be seen, more importantly was the moral obligation we need to take for our construction workers, the public, and the environment.

 

Dust Emissions --- Does Your Vacuum Leak Dust?

Poured in place urethane gasket, beneath the head of a Dust Director Vacuum.Urethane Motor Head Gasket.  Beneath the motor head of every Dust Director® Vacuum & Cyclone is a poured-in-place urethane gasket that is used to ensure a positive airtight seal between the motor head and its tank.  Commonly used shop vacuums and even higher priced vacuums will use foam or nothing at all.

The urethane gasket ensures against dust leakage into your work area and prevents even the slightest loss of vacuum which would naturally reduce suction power.  Many wonder how the suction of a Dust Director® Vacuum and Cyclone seems so much more powerful than other brands, one of the reasons is the urethane gasket.

Dust Director's Increase in Suction Power?  While a complete Dust Director System (vacuum and dust guard) have been successfully monitored by NIOSH to operate within the guidelines of their established PEL, a very important  feature in all of the Dust Director® Vacuums and Cyclones is the poured-in place urethane gasket.

While some vacuums use foam as a gasket, 90% of all vacuums use nothing!  This startling statistic includes vacuum's that cost well over $2000 dollars.  While the Rigid vacuum, for example, does not use any type of gasket (while leaking profusely), the consensus among morally conscience contractors is a Rigid vacuum is simply not designed to be used for silica dust containment.

On a visit to masonry tuck pointers in Chicago and Detroit, the suction power of the Dust Director® Vacuums was compared to the Bosch 3931 Airsweep, Hilti VC20 and Fein Turbo I vacuums.  Simply by placing our hand over the inlet port of  each vacuum, the following was the agreed upon results:

bullet

Dust Director® Model DD1000:  15% greater suction vs. Bosch & Fein, 25% greater suction vs. Hilti

bullet

Dust Director® Model DD1200:  Easily 20% greater suction than the DD1000

bullet

Both Dust Director® models where considerably lighter than Bosch, Fein and the Hilti vacuums.
