ARDEX Americas is
a global leader in the development, manufacture and distribution of
high-performance specialty building products for commercial and residential
applications. ARDEX is committed to maintaining the highest standards for
Quality, Performance and Safety within the construction industry.
(Occupational Safety and Health Administration) has recently issued a new standard for the construction industry which requires employers to limit worker exposures to
respirable crystalline silica and to take other steps to protect workers.
In this ruling, OSHA has established
Permissible Exposure Limits and Action Levels (the level of exposure which
triggers required protection methods). The newly established OSHA PEL and
Action Level compliance schedule for Construction Industry went into effect
Sept. 23, 2017. For complete details; https://www.osha.gov/silica/SilicaConstructionRegText.pdf
Because all construction employers covered by
the standard are required to establish and implement a written exposure control plan, ARDEX has conducted a series of tests with
an independent outside lab to provide to our customers the exposure statistics
for our different product lines as well as mixing methods.
ARDEX Testing and Compliance
As part of its
own compliance plan, ARDEX has had exposure monitoring conducted by
an Independent Certified Industrial Hygienist (CIH) for both the manufacturing
of its materials as well as the ultimate product application in our field and
in our training centers. It has also been confirmed that all appropriate
control measures are in place at all ARDEX Academy training locations to ensure
the safety of our technicians and our attendees.
The results of this initial testing, intended to cover all
primary products, are as follows:
For products with no sand added like ARDEX FEATHER FINISH® finishing underlayment,
respirable crystalline silica exposure was measured as “none-detected” and below the Action Level during mixing. Mixing ARDEX products with no sand added does not require
engineering control measures like additional ventilation or dust mask to comply
with OSHA Silica Standard.
For sanded products like ARDEX V 1200™ Self-Leveling Underlayment, respirable crystalline silica exposure was measured below the
Action Level during mixing with an ARDEX
DUSTFREE™ on mix barrel, connected to portable vacuum, with HEPA filters. Mixing under these
conditions will not require dust
mask to comply with OSHA Silica Standard.
Technical Update: Clarification on Unsanded Materials and Crystaline Silica
For all other
products and mixing methods, we are currently conducting testing and will be
publishing the results as they become available.
