In August 2014 the Pipeline and Hazardous Materials Safety Administration (PHMSA) was taking actions to raise awareness of the hazards associated with compressed gas cylinders following a large propane cylinder rupture on a food truck in Philadelphia, PA, that resulted in deaths and injuries.
Their campaign focused, in part, on the basics of how to inspect a cylinder for serviceability, and how to identify an out-of-test cylinder.
Additionally, on January 21, 2016, requalification changes for cylinders were adopted by PHMSA.
PHMSA published a final rule in the Federal Register, titled “Hazardous Materials Adoption of Special Permits (MAP-21)(RRR)” under Docket No. This final rule incorporated longstanding DOT special permits into the Hazardous Materials Regulations (HMR).
Cylinders must now be requalified by proof pressure or volumetric expansion testing every 10 years instead of every 7 or 12 years.
Fire marshals and code enforcers play an important role in helping to achieve public safety, and we have shared responsibility in this area.
Both propane (Class 2.1 Flammable Gas), and the cylinder to which it is stored, are regulated by the HMR.
Cylinders containing flammable gases are required to fully conform to the packaging, qualification, maintenance, and use requirements of the HMR.
In addition, State and local fire codes may also place requirements on low-pressure cylinders of flammable gas.
Like many Canadians, I studied piano via the Royal Conservatory of Music (RCM).
I started when I was 5 and by the age of 18 I had completed my Grade 10 RCM piano certificate and I was all set. What was the goal of my 13 years of classical piano training?
I wasn’t going to school to study classical music, and my musical tastes, though they include classical music, are quite diverse. I got to grade 10, but most teenagers stop at grade 8 or before because they lose interest and don’t want to sit around playing Mozart and Debussy for their friends (and their friends don’t care to listen). They want to play and sing the songs they like on the radio, and maybe jam with their friends.
