Changes in Regulation of Agricultural Anhydrous Ammonia

The purpose of this letter is to make Agricultural Anhydrous Ammonia handlers in Iowa aware of new Anhydrous Ammonia Standards and changes the adaptation of the new standards and exceptions may bring. On December 15, 2014, CGA (Compressed Gas Association) received a Notification of Final Action on ANSI/CGA G-2.1, 2014, Safety Requirements for the Storage…...

Do you “certify” your 3-year PSM/RMP compliance audits?

Not a trick question but boy do we get “the look” when we ask the question just as it is written in 68.79 and .119(o).  What do OSHA and EPA mean by certifying an audit?  Who does this certification? Is this a formal exercise of certifying?  Why did OSHA/EPA use this term in the standard? …...

Consider the assumptions made during a PHA Facility Siting Assessment (Pipe Bridges)

I recently participated in a PHA for a large flammable liquids process and during the “facility siting” portion of the PHA we took a detailed tour of the process. During which, several significant “impact” hazards were identified. Of course, the long-time engineering manager (40 plus years of fine service at the facility) quickly went to the…...

A look into what EPA expects in our RMP 3-year audits

Recently EPA issued a Consent Decree in response to a company that had two (2) facilities inspected under the Risk Management Plan Rule (40 CFR Part 68).  The document was much like the many others I have posted here; however, this agreement contained a lengthy audit plan that EPA and the company agreed to as…...

MOCs are much like WORD or EXCEL… they can do so much more than we use them for

For the life of me, I can not figure out the aversion to doing MOCs.  I am guessing that my experiences in Petrochem were not the norm, as we used our MOC process for just about everything under the sun.  Heck even the QC group used our MOC process.  We rarely questioned the value of…...

PSM Battery Limit Scenario w/ gas cylinders stored within the same building w/ NO passive fire barrier separation (OSHA LOI)

I found this latest Letter of Interpretation regarding PSM Battery Limits an interesting read.  The scenario is VERY COMMON and I am so glad OSHA wrote this letter!  OSHA reminds us that cylinders stored in the same fire area (e.g. a fire has no passive control(s) to prevent its spread) that ALL of the cylinders…...

FM Global Data Sheet beat CSB to punch on Hydraulic Fracturing in NH3 Refrigeration Systems

Those of you that visit SAFTENG often know that I love the FM Global Data Sheets!  These data sheets are NOW FREE (and have been for a couple of years).  They serve as a GREAT AID in helping facilities understand their hazards and risks associated with all kinds of industries.  In fact, although my practice…...
