NIOSH releases report on Maine Lumber Mill silo fire and subsequent explosion that killed two firefighters and critically injured 13 more

NIOSH has released its Fire Fighter Fatality Investigation report regarding the Maine Lumber Mill COM DUST explosion. Lots of learnings in this report. Fire origin and explosion cause The State Fire Marshal’s Office and Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) cause-and-origin preliminary investigation classified the fire as accidental. It indicated that the area

OSHA looks to recind the Construction Lighting standards

I almost never write about construction safety matters as I do not practice in that safety arena. But lighting crosses all industrial sectors, and this effort by OSHA to recind the Construction Lighting standard(s): 1926.26 and 1926.56 is very puzzling to me. 29 CFR 1926.26 requires construction areas, aisles, stairs, ramps, runways, corridors, offices, shops,

Chemical Safety Regulatory Alignment Pressure

A coalition of 75 major industry organizations (led by the American Chemistry Council) submitted a joint petition to OSHA, the EPA, and the Office of Management and Budget (OMB). The Goal is to establish a single, unified federal chemical safety standard to eliminate conflicting regulatory requirements between OSHA standards and the EPA’s Toxic Substances Control

Line Break Gone Bad – Maintenance Mechanic Dies After Being Burned by Hot Boric Acid Solution While Removing Pump

In July 2012, a 64-year-old maintenance mechanic at an aluminum foil processing facility died after being exposed to an approximately 180-degree Fahrenheit solution of boric acid and water while trying to remove a recirculation pump from its housing. The pump was part of a boric acid evaporation system. The system took several days to completely

Hydrostatic Pressure Test gone bad (49-year-old pipefitter killed)

I have written a lot about the hazards of “pressure testing” piping, and in all of those posts I have stated how much “safer” Hydrostatic Testing is, compared to pneumatic testing. But this fatal accident shows us that even hydrostatic testing comes with fatal risks. During a hydrostatic pressure test of a fire suppression system,

Understanding the PRCS Ventilation table from “AT&T Standard Section 620-140-501” (1976 edition)

The AT&T Standard Section 620-140-501 (often referred to as Bell System Practice, or BSP, 620-140-501), published in June 1976, is a foundational safety document for the telecommunications industry. It outlines the strict procedures for testing, purging, and ventilating manholes and other confined spaces before and during employee entry. Because telecommunications workers frequently operate in underground

Using AI to establish my ventilation rate for a Permit-Required Confined Space entry using OSHA’s Alternative Entry option 1910.146(c)(5) or 1926.1203(e)

I have a 10,000-gallon storage tank that I need to ventilate with forced-air ventilation. My program states I need to achieve at least 7 air changes per hour. What CFM blower do I need to achieve this? This is the question I asked Google Gemini 3.1 Pro, and I’ll be damned, it was SPOT ON!
