Our OSHA and Cal/OSHA Practice stands out because of its deep bench of true specialistcropped-cmc-logo-high-res-002-3.jpg attorneys with a singular focus on workplace safety and health law, and because of our personal connections with the key players within OSHA and Cal/OSHA.  Despite the firm’s “boutique” size, as an OSHA and Cal/OSHA practice, we have the deepest bench of true specialist attorneys and professionals in the entire country. The Chair of the national OSHA Practice, Eric J. Conn, practiced for more than a decade alongside the first General Counsel of the OSH Review Commission, learning OSHA law and its context from the attorney who wrote the first decisions and interpretations of the OSH Act and OSHA’s regulations. Fred Walter, Of Counsel for our Cal/OSHA practice has practiced before Cal/OSHA for decades. OSHA Partner Kate McMahon is a former safety and environmental advisor on Capitol Hill.  Aaron Gelb heads our Midwest OSHA Practice out of our Chicago Office, Kimberly Richardson is our process safety guru, and Nick Scala leads our Mine Safety Practice.

All of these attorneys maintain close relationships with senior OSHA and Cal/OSHA officials. As a result, the firm’s national OSHA practice group has unique insight not only into workplace safety law, but also into the workplace safety regulatory agencies.

Chemical Manufacturing

  • Represented a specialty chemical manufacturer in multi-agency (OSHA, CSB, EPA, ATF, U.S. Coast Guard, and a state environmental regulator) investigations, inspections, and enforcement actions arising out of a catastrophic explosion in a reactor that resulted in two fatalities. OSHA’s enforcement action was cut by more than half; violations alleged by OSHA to be “Willful” and “Repeated” were withdrawn or re-characterized.
  • Oversaw the on-site inspection under the PSM Covered Chemical Facilities National Emphasis Program of a high-profile chemical plant in West Virginia. A team of four compliance officers, including two PSM specialists from OSHA’s Salt Lake City Technical Center, spent more than two months scrutinizing all elements of the PSM Standard at the facility. At the conclusion of our work, OSHA did not issue any citations.


  • Represented a construction general contractor in OSHA investigations of fatal construction accidents raising complex multiemployer worksite citation policy issues at Baltimore-Washington International Airport, the Pentagon, and Fort Meade. The result — No citations at any location.

  • Managed multi-agency investigations of one of the most significant combustible dust explosions in history. The explosion injured 42 employees, including six fatalities. We established an on-site Command Center, coordinated the investigation of a team of forensic experts, and managed the investigations and inspections of federal OSHA, state OSHA, CSB, EPA, DNR, ATF, FBI, SBI, the State Fire Marshal, insurance investigators for dozens of entities, and numerous plaintiffs’ attorneys. The process involved conducting hundreds of interviews and producing hundreds of thousands of pages of records. In the end, nearly half of the citation items were withdrawn and the penalty was reduced by 83%.
