3-way valves have grown in popularity over the past 10-15 years, as they have begun to find their way into relief systems. Today, codes allow “relief trees” to be used, so Pressure Safety Valves can be changed out without emptying and degassing the vessel. The 3-way valve is the means by which the PSV is […]
If you can’t tell, I am having a ball playing with these AI systems. And to be honest, my numbers were a bit more conservative than Gemini and Grok, but darn, they were excellent answers that are SOLID nonetheless. These AI tools may make amazing tools for PRE-PLANNING for Pool Fires and FOAM INVENTORY needs.
My question: How much water flow in GPM is necessary to cool a 1,000 gallon LPG tank that is involved in a pool fire to prevent it from experiencing a BLEVE? Their answer… Google Gemini is learning who I am! Given your work with SAFTENG.net, you likely know that while 55 GPM is the “engineering”
Yes, there are two (2) types of BLEVEs, and much like the myth that BLEVE’s only happen to Pressure Vessels with liquified flammable gases, COLD BELVEs account for nearly 25% of all BLEVEs. So what is the difference between the two? Super GROK explains it better than I could… A BLEVE (Boiling Liquid Expanding Vapor
I continue to play with and test Google Gemini Plus and Super GROK in the OSH and Process Safety space. Today, my question to both was: How much of a Class II flammable liquid will it take to burn under a 1,000-gallon LPG tank to cause a BLEVE? BOTH of the systems had outstanding answers!
I am not sure who, where, and when this dirty little lie began, but we have been seeing an incorrect application of NFPA 70, 500.7(K) Detection System for Flammable Gases, item (3) Interior of a Building or Enclosed Space. It seems businesses are looking for any way out of having an electrically classified area and many are
We routinely find facility siting issues when LPG Tank(s) and Flammable Liquid Tank(s) are located in the same area. OSHA, NFPA, IFC, etc., all require a separation distance between the two (2) types of tanks. This is ALL about preventing a setup for a BLEVE, as a pool of flammable liquid finding its way under
An ammonia system at an industrial food processing facility over-pressured, activating one of its overpressure safety relief valves. Ammonia was released into the atmosphere for approximately eight (8) minutes until the refrigeration compressor was manually shut down by disconnecting the supply power, and the pressure in the system was reduced.

Lead the PHA team to think through the safeguards that are in place that are intended to:
This report summarizes the enforcement activity for the water and wastewater utility sector. During this period, 63 citations were issued across 18 inspections, resulting in $830,945 in penalties. Executive Summary of Penalties and Citations The data indicates that while Hazard Communication and Respiratory Protection are frequently cited, the vast majority of the financial impact stems
Reporting Period: October 2024 – September 2025 This report summarizes the enforcement activity for the chemical manufacturing sector over the past fiscal year. With 883 total citations across 264 inspections, the industry faced over $3.78 million in penalties. Executive Summary: The “Top 5” Risk Areas The majority of financial and safety risks is concentrated in
An HSE investigation found clear failings leading to two (2) separate incidents of exposure to caustic soda at a manufacturer. The chemical manufacturing company has been fined £3.8 million ($5.1 million in USD) after two (2) employees at two (2) separate sites suffered serious chemical burns as a result of exposure to sodium hydroxide, known
