Pressure Vessel Failure during Hydrotest – Nov. 2007, ChinaPlease see the photos below of a pressure vessel that recently failed whilst under hydrotest during post fabrication testing. This vessel was manufactured by a vessel vendor in China and the plate was of Chinese mill origin. Unfortunately this is another example of serious equipment/material failures with
Star elementary school Oklahoma 1982. Six children & one adult killed, 42 injured. The cause was an 80-gallon hot water heater exploded. The controls had been tampered with, the temperature probe was removed & the relief valve was improperly installed.
This is not the first time I have addressed this matter. Still, somehow, somewhere, a dirty little lie has been circulating among ammonia design and installation contractors that somehow an engine room handling less than 10,000 pounds of anhydrous ammonia (NH3) is incapable of presenting an explosion hazard, thus no need for any engineered ventilation.
Some specialized literature regarding the maintenance of safety relief valves (SRVs) is available, but it is best to always consult the manufacturer’s detailed installation and maintenance manuals on the subject, as some type of valves might require special attention. It is highly recommended to always use genuine manufacturer’s spare parts. In some parts of the
Almost all Occupational Safety and Health efforts need one key ingredient to be successful… Employees participating in the safety process! Heck, OSHA and EPA have even regulated employee participation (EP) in their process safety standards. But far too many organizations have not quite understood the concept of Parent-to-Parent engagement vs. Parent-to-Child engagement and almost all
The requirements for bonding and grounding of containers during the transfer of Class I flammable liquids are contained in 29 CFR 1910.106(e)(6)(ii). This paragraph does not specifically address plastic containers. However, OSHA issued “OSHA Instruction STD 1-5.14-A” on October 24, 1980 to address plastic containers (NOTE: this STD is NO LONGER AVAILABLE via OSHA.gov). This
Illinois Environmental Protection Agency Director has asked the Illinois Attorney General’s office to proceed with enforcement action against Ellinor Trucking and River Rock Logistics, operated out of Lanark. The Illinois EPA alleges an inadequate transfer hose was used when an Ellinor employee prepared to offload anhydrous ammonia to an above-ground storage tank, which resulted in
Following the guidance of OSHA and EPA, the industry has attempted to simplify what type of change requires the initiation of the Management of Change system and which type of change is a “replacement in kind” (RIK). Oddly enough, both OSHA and EPA chose not to define the meaning of “change”; instead, they have officially
The elements that form the safety culture maturity model have been adapted from the safety culture components listed by the HSE in Reducing error and influencing behavior – HSG48. It is unlikely that these elements will map precisely onto the factors that companies have previously measured in safety culture or climate surveys because there is
On January 26, 2006, a factory in Brazil witnessed a significant accident during a pneumatic pressure test involving a tank and pipework. The incident occurred because blind flanges were not used to isolate the pipework connected to the tank. Instead, only the valves were closed. This oversight led to the possibility that one or more
Public exposure guidelines are intended to predict how members of the general public would be affected (that is, the severity of the hazard) if they are exposed to a particular hazardous chemical in an emergency response situation. The most common public exposure guidelines are: AEGLs (Acute Exposure Guideline Levels) ERPGs (Emergency Response Planning Guidelines) TEELs (Temporary Emergency Exposure
