The state of OH is currently working on its next revision of the State Fire Code. As in the past, the basis for these revisions comes from the International Fire Code (IFC). One major revision for those in the state of OH will be Section 916 – Gas Detection. This is an EXCELLENT RAGAGEP for […]
Big changes in the Province of British Columbia for boilers, pressure vessels, and NH3 refrigeration processes. The Province has published Ministerial Order M225-2024 that provides amendments to the Power Engineers, Boiler, Pressure Vessel and Refrigeration Safety Regulation (PEBPVRSR). These amendments will update the Schedule to the PEBPVRSR by adopting the new editions of the codes.
The day has arrived! IN-OSHA, a state-plan agency, has issued a citation to a chemical manufacturer regarding its Safety Data Sheet (SDS) for Ammonium Hydroxide (NH₄OH). OSHA took issue because the SDS did not provide the LEL/UEL range for this chemical. Now I could argue that NH₄OH is NOT a flammable liquid, and therefore, this
This is the first and only PSM citation that I have seen from IN-OSHA. It is a single violation cited for contractor safety, and it appears it may have been related to an incident involving a contractor working on an Ammonium hydroxide tank. I am NOT certain about this, just trying to read between the
A client has a new tank farm, and six (6) storage tanks are in identical service, and three (3) others are in similar service. So the question I get often is… Since these tanks are identical in their design AND service, can we use inspection data from one (1) tank to assess the conditions of
A summary of API’s 510 Inspection Frequencies: (emphasis by me)
When classifying your piping circuits for MI/TML/CML inspections, DON’T share the inspection/NDE frequencies with the team!!! It is amazing to watch them “reconsider” their decisions after they learn the differences in inspection frequencies between Class 1 and Class 2. The exercise is to ENSURE the integrity of our PRIMARY CONTAINMENT (process safety); not to reduce
SAFTENG NOTE: The fatal H2S event in Deer Park last year that claimed two (2) contractor lives was the result of contractors opening the WRONG flange! Now we have a similar event that led to a fire that burned for three (3) days. A report regarding a 2025 Refinery Fire in CA found that two
The Compressed Gas Association (CGA) has published P-95, Guideline for the Safe Installation and Use of Cryogenic Food Freezing and Chilling Equipment. This publication covers the installation and operation of food freezing and chilling equipment and associated supply systems, and the use of that equipment with refrigerated liquefied gases (nitrogen and carbon dioxide).
This paper concerns refrigerant gases classified as Division 2.1 flammable gases under the Australian Dangerous Goods Code (ADG Code) or classified as Flammable Gas Category 1 using the Globally Harmonized System (GHS). It covers general work health and safety/occupational health and safety (WHS/OHS) duties, however, readers should check their legislative responsibilities at the state/territory and
On 6 December 2016, an operator at a liquefied petroleum gas (LPG) processing facility heard a loud noise coming from an area of the plant during start-up, following major maintenance on the process. The operator identified that high-pressure, flammable gas was being released to the atmosphere from a point beneath the insulation of process equipment.
In April 2024, a regeneration gas heater ruptured at a gas processing plant due to an overheated electrically heated regeneration vessel. Regeneration gas heaters are commonly used in the regeneration of molecular sieve dehydrators with the recirculation of dried natural gas heated to 250 degrees Celsius throughout adehydrating purge cycle. The initiation of manual operating
