Understanding NJ TCPA for Effective Reactivity Management

The New Jersey Toxic Catastrophe Prevention Act (TCPA) has recently been amended to cover reactive chemicals and is the only regulation that requires as assessment of reactivity hazards and mitigation of associated risks. The Reactive Chemicals section of this regulation lists specific chemicals and functional groups along with corresponding threshold values that serve as trigger points for conducting reactive hazard assessments. This paper provides a simplified description of the Reactive Chemicals section of TCPA and associated compliance issues. Read more

Update Your HAZCOM Program for Combustible Dusts

According to the “Status Report on Combustible Dust National Emphasis Program,” published by OSHA in October 2009, the Hazard Communication (HazCom) standard is the most frequently-cited standard with respect to combustible dust-related hazards. This paper can help you determine what type of information you need to develop and include on your Safety Data Sheets (SDSs). Note that the recent update to the HazCom standard refers to material safety data sheets (MSDSs) as safety data sheets (SDSs). A link to this update is included at the end of this paper. OSHA’s Hazardous Communication Standard, 29 CFR 1910.1200, requires manufacturers and importers of chemicals to conduct a hazard evaluation of chemicals they produce or import. The results of this evaluation are to be included on a SDS and any container labels. Employers must then maintain these SDSs in the workplace and develop a written program to communicate to workers this hazardous chemical information. Although always intended to be included in HazCom programs, the most recent update to this standard, on March 26, 2012, added “combustible dust” to the definition for a hazardous chemical. Read more

Using a Burning Rate Model for Deflagration Vent Sizing

Being able to accurately size deflagration vents is critical to safe, efficient operation of combustible dust handling equipment. NFPA 68 provides simple calculation methods for sizing deflagration vents for combustible dust deflagrations. Read more
