Easy Work Practice Solutions That Reduce Respirable Crystalline Silica Dust

OSHA’s new Respirable Crystalline Silica Dust Standard sets very strict standards for exposure, and contractors across the United States are developing their compliance playbook to mitigate risk. Employers must limit access to high exposure areas; provide training and respiratory protection; develop written exposure control plans; and begin to measure exposures starting in 2018.

The Nox-Crete team thinks the best way to prevent health problems related to silica dust is to avoid silica dust altogether. Several of our high-performance chemical and accessory solutions reduce the need for grinding and sanding Tilt-Up wall panels. Less grinding, less dust.

Reduce Grinding Requirements to Limit Exposure

Several products in the Nox-Crete Tilt-Up segment can be implemented as dust control work processes to meet the new OSHA requirements. First, chemically active Silcoseal cure and bondbreaker products deliver uniform and consistent panel separation. Clean panel separation with Silcoseal reduces wall panel grinding and patching requirements, thereby reducing worker exposure to silica dust.

Adding TP-Joint as a preventative work process will eliminate the traditional grinding of concrete “fins” on erected wall panel surfaces. TP-Joint is a pre-molded, flexible temporary floor joint filler that easily fits into saw cut floor/casting slab floor joints to prevent concrete seepage. Easy to install, TP-Joint is also easily removed without the use of any special tools or the need for resawing.

Better Reveals Reduce Dust

Rustication and reveal products made with wood, or porous blown PVC have a tendency to stick in Tilt-Up wall panels, which requires grinding along the entire length of each strip. Grinding, patching, sanding and sealing every inch exposes the team to unacceptable limits of silica dust.

Nox-Crete offers Clean Line Reveal, a high density extruded PVC rustication and chamfer strip. Because Clean Line Reveal won’t cause sugar retardation or expand like wood - you get a full surface contact and tighter joints that release clean from tilt-wall panels. Using Clean Line Reveal will greatly reduce the exposure to silica dust.

Use Smooth Textured Patching and Finishing Compound to Minimize Sanding

Creamy Panel Patch from Nox-Crete repairs minor surface defects on tilt-up wall surfaces, such as: air voids (bug holes), honeycombs, spalls, gouges, chips and scratches with no grinding and only minimal sanding prior to painting. With a unique blend of Portland cement, acrylic polymer modifiers and ultra-fine aggregates, high strength Panel Patch trowels out smoothly to a feather-edge thinness without any coarse, gritty feel.

Panel Patch delivers an exceptional bond to concrete and masonry surfaces, and is color-blended to match natural concrete. Because it dries in as little as 15 minutes, Panel Patch can be painted the same day.

Include Preventative Work Processes in Written Control Plans

The new rule requires employers to have a written exposure control plan that describes the following:

  • The tasks that could expose workers to silica dust
  • A description of the engineering controls, work practices, and respiratory protection used to limit exposure for each task
  • The housekeeping measures and restricted work area procedures used to limit exposure

Your written exposure control plan can also include anything else you think is important about keeping your employees safe from respirable crystalline silica at your worksite. Use Nox-Crete dust control products as a preventative work process to avoid grinding concrete.

Change is inevitable, but staying ahead of this new regulation doesn’t have to kill your profits. In fact, by taking advantage of next generation solutions from Nox-Crete, your operations can run more efficiently to give you an edge on your competition.

Silica: The Nitty Gritty

  • Workers who inhale very small crystalline silica particles are at increased risk of developing silicosis, an incurable and sometimes fatal lung disease.
  • About two million construction workers are exposed to respirable crystalline silica in over 600,000 workplaces.
  • Respirable crystalline silica is a worker safety issue, which has big implications on recruiting and retaining new construction workers.

Nox-Crete Pro: A.H. Harris

In this first edition of Nox-Crete Pros, Nox-Crete Products Group puts the spotlight on A.H. Harris and its willingness and excitement to work together to find the best solutions for customers.

AHHARRIS

Building Trust

Customers put a lot of faith in A.H. Harris to recommend products and present them with innovative solutions. That trust exists because A.H. Harris is truly invested in all of its business relationships.

Alan Gould, A.H. Harris account manager in Maine, said he believes in becoming a business partner with customers and manufacturers. And Eric Leone, owner of Leone Concrete Corp. in Newport, Maine, definitely agrees that Alan and A.H. Harris are partners, as well as problem solvers.

“The big thing with A.H. Harris is that so much of what we do in cast-in-place and concrete formwork is specialty work,” Eric said. “We have unique form issues and design challenges. When you’re coming up with solutions, you have to have a good relationship with your supplier. A.H. Harris is a great resource to bounce ideas off of or to supplement what we have going.”

Liquid Hardeners Realize Maximum Performance When Applied After 28 Days

Patience is a Virtue - Testing Confirms Liquid Hardeners Realize Maximum Performance When Applied After 28 Days

A growing trend within the concrete flooring industry is to apply liquid hardeners on freshly-troweled concrete in what is referred to as a “pre-seal” or a “cure-coat.” Conversely, Nox-Crete has historically advised applicators to wait and apply liquid floor hardeners a minimum of 28 days after concrete placement to allow for maximum performance. The 28 day recommendation was based on intuition and a strong understanding of the chemistry behind liquid floor hardeners and the means by which they densify concrete surfaces. The lack of conclusive data led Nox-Crete to not only ask but to answer the question, does the timing of the application (Day One vs. Day 28) impact the liquid floor hardener’s ability to improve abrasion resistance?
