This is not the first time I have suggested using other government regulations to improve our baseline safe work practices. But WorkSafe BC has done such a nice job in this publication that all we need to do is cut and paste these isolation requirements into our current confined space entry program. These isolation requirements are just OUTSTANDING practices that offer a much higher level of CS Entry safety and should be considered by all - regardless of where the space is located. Anyone who is looking for some concrete energy isolation practices to implement for entry into their PRCS's these are without a doubt the best.
Revision 16 of this pamphlet includes the addition of a section on fully-lined valves (4.1.9), a more robust section on liquid expansion chambers (5.5), recommendations on plastic pipe selections and discussion on gas permeability under vacuum (9), a caution on pneumatic testing (11.2.2), updated guidance on hydrostatic testing (appendix A, 2.3.1), and addition of a definition of deformation pressure (Appendix A, 2.6). This product is available as a free download HERE.
Recently, the Get Address feature broke in all MARPLOT 4.x versions, because the Google web service that MARPLOT was using was discontinued.
The MARPLOT 4.2.4 release fixes the Get Address feature, which now uses a newer version of Google's Reverse Geocoding tool to find the address at a click point. No other changes have been made in this release.
New versions of CAMEOfm and Tier2 Submit will be released in the next few weeks. We are also in the process of a developing a completely new MARPLOT. We don't have a specific release date for the new MARPLOT 5.0 yet, but we hope to release it sometime in late winter.
This is an interesting citation, one that to me appears OSHA was not happy with this employer. As I was reading this decision, I was absolutely shocked that OSHA would have issued a citation, much less a Serious, in this situation. If all employers did 1/4 of what Cargill does at this facility for PRCS entry then there would be MUCH LESS tragedies in PRCSs! I usually do not mention company names in these types of postings, but when a company does things right I do believe they should be acknowledged and in this case Cargill was SPOT ON and should be recognized - not penalized. This case involved Cargill using the Topeka, KS Fire Department as their PRCS Rescue Service. OSHA took issue with the fact that it took 4-5 minutes for one of the stations to respond and when this station went out on other calls, the other stations were staffed with trained rescuers and even those stations could arrive within 4-7 minutes. The court even used response records to establish response times from the stations. I will add this, Cargill won this because the other stations were staffed with rescuers who too could arrive on site in a timely manner. Had this not been the case, this decision may have turned out in favor of OSHA. Here are the facts:
One area that is often overlooked or not applied during process hazards analysis (PHA) is a review of previous incidents. This is often not done as the process has no reported incidents in the past five years. We can discuss/challenge that "phenomenon" in a later posting; but I wanted to offer this bit of advice...
With the release of the CSB accident report involving the catastrophic failure of an ASME pressure vessel and me posting it this afternoon, I am already getting e-mails (5 and counting within the first two hours) claiming the incident is "1 in a million" and that I am scaring people for no sound reason. Really? How often do we think accidents involving a pressure vessel occurs? Do we actually think they are truely 1 in a million or at some other frequency? Well, here is the actual data over a 10 year period (1992-2001) from the National Board of Boiler and Pressure Vessel Inspectors...
This accident occurred December 7, 2009, with a violent rupture of an ASME pressure vessel. The video contains an animation which depicts the stress corrosion cracking (SCC) that accumulated over time in the walls of a pressure vessel where synthetic quartz crystals were manufactured under extremely high pressures and temperatures. The incident had many failures and is a case study on PRESSURE VESSEL MANAGEMENT. Improper design, construction, testing, and inspection ALL played a roll in this CATASTROPHIC FAILURE of an ASME PRESSURE VESSEL. So the next time anyone tells you "these vessels just do not have a history of failing"... well now you know!
OSHA is considering revising its Process Safety Management (PSM) standard, 29 CFR 1910.119, to address gaps in safety coverage; or updating its Flammable Liquids standard, 29 CFR 1910.106, and Spray Finishing standard, 29 CFR 1910.107, based on the latest consensus standards. The following options are being considered:
The first (1st) public review of draft standard IIAR 4-201x, Installation of Closed-Circuit Ammonia Mechanical Refrigerating Systems is now open. Substantive changes resulting from this public review will also be provided for comment in a future public review if necessary. IIAR 4 specifies criteria for the installation of closed-circuit ammonia refrigeration systems. It presupposes that the persons who use the document have a working knowledge of the functionality of ammonia refrigerating system(s) and basic ammonia refrigerating practices and principles. This standard is intended for those who are involved with the installation of closed-circuit ammonia mechanical refrigeration systems. This standard shall apply only to closed-circuit mechanical refrigerating systems utilizing ammonia as the refrigerant. It supplements existing general refrigeration standards issued by IIAR and other organizations such as ASHRAE, ASME, and ANSI. It is not intended to supplant existing safety codes (e.g., model mechanical or fire codes or ASHRAE Standard 15).
Few people have the passion and care for the field of safety as Bryan. Having watched his work in the industry for many years and often leaned on his counsel, he is a trusted brother in our trade. The tireless work he does in collecting and posting "Incident Alerts" (and his honest observations) ...
