Update On Proposed Rule On Hexavalent Chromium

Words: Dan KesterWhile OSHA appears to be on track to finalize its standard on occupational exposures to hexavalent chromium by January 18, 2006, there remains a great deal of concern about the proposed PEL (permissible exposure limit). The level proposed is so low (1 microgram per cubic meter) that many businesses have made it clear to OSHA that they will probably close their doors rather than spend money to upgrade their facilities only to find out that the new technologies don't help them achieve the PEL. The proposed level is 50 times more stringent than the current standard and 50 times more stringent than the exposure limits of our major trading partners in Europe and Asia.

In an effort to bring these concerns to the forefront before the rule is finalized, Congressman John Boehner, Chairman of the House Ed and Workforce Committee and Congressman Charlie Norwood, Chairman of the Workforce Protections Subcommittee, sent a letter to Josh Bolton, head of the Office of Management and Budget asking that the agency thoroughly examine all the scientific evidence presented on the standard. Apparently recent analyses submitted to OSHA during the comment period suggest that the agency failed to include whole industry sectors with many small businesses in its assessment of the proposed rule.

A letter (spearheaded by Senator Kit Bond (R-MO)) and being circulated for signatures of other Senators will also be sent to Labor Secretary Chao asking her to insure that OSHA fully assesses the technological feasibility of the proposed limit and the potential adverse consequences of the rule on American jobs and competitiveness.

By some estimates, the cost to the U.S. economy for a PEL this low will easily exceed $3 billion annually - far greater than OSHA's estimated cost of $220 million and could make this rule one of the most expensive federal regulations in years.

This is an important issue for our industry because of the potential precedent the rule could set for silica.

May 2026

Masonry has defined architecture for centuries, prized for its strength, durability, and timeless aesthetic appeal. From historic sites to modern designs, masonry buildings are durable and visually distinctive. However, exposure to moisture, freeze-thaw c

Rethinking Shelf Angle Design for High-Performance Masonry Walls
May 2026

If you've been around masonry construction long enough, you know the shelf angle is one of those details that’s easy to take for granted. It’s been used the same way for decades, set it at the slab edge, support the veneer, move on. But as building requir

When Schedules Tighten, Experience Shows
May 2026

In construction, schedules rarely open up; they tighten. Weather delays, trade coordination, and last-minute scope changes all add pressure, even on jobs that were planned down to the minute. When that happens, experienced masons don’t start cutting corne

Shelf Angles and Their Impact on Wall Performance
May 2026

Shelf angles have long been a standard component in masonry construction. Installed at the slab edge, they provide support for brick veneer and are often treated as a routine detail. However, as building performance requirements evolve, particularly aroun
