Chemical Safety Board (CSB) chairman John Bresland Video Clip

Chemical Safety Board (CSB) chairman John Bresland calling all state and government in US to adopt the Pressure Vessel Code and Boiler Standard for the design and fabrication of pressure vessel. Improperly installed or modified pressure vessels have led to a number of serious chemical accidents. Eleven states still don't require adherence to the ASME pressure vessel code. All states and localities should adopt this code and related boiler standards; lives will be saved as a result.
