Permit Required Confined Spaces

How does a 10-day old water valve pit obtain a 9.2% Oxygen atmosphere?

Another Fatality OSHA Case file involving a Water Valve Pit (Hazard Information Bulletin regarding Asphyxiation Hazard in Pits: Potential Confined Space Problem) – a SINGLE entrant (the job foreman), a would-be-rescuer, and potentially another would-be-rescuer.  The water valve pit was 7 ft in diameter and 16 ft deep.  The vault contained a 12″ water main…...

Fuel vaults are PRCS’s (OSHA Fatality Case File)

A few weeks ago we were debating in my FaceBook Group about these vaults being a PRCS.  The picture in question (shown to the left – full scale in the article) had a working platform just a little more than 4′ down inside the vault, but the fixed ladder went all the way down to…...

Water Valve Pits are Permit-Required Confined Spaces (1926 Subpart AA – Confined Spaces in Construction)

We go all the way back to 1996 and OSHA issued a Hazard Information Bulletin regarding Asphyxiation Hazard in Pits: Potential Confined Space Problem.  Fast forward 23 years later and we have this:  At 2:23 p.m. on July 8, 2019, a worker employed by a utilities construction company was working in an underground vault. He…...

Double Block and Bleed – OSHA vs API

The only OSHA standards that make mention of the phrase “Double Block and Bleed” (DB&B) are its Permit-Required Confined Space (PRCS) standards. In both 1910.146(b) and 1926.1203, OSHA defines a DB&B as: the closure of a line, duct, or pipe by closing and locking or tagging two in-line valves and by opening and locking or…...

Has OSHA’s Permit-Required Confined Space standard met its goal?

With year 2020 already claiming 7 lives inside PRCSs within the USA, I have to ask the question:  Has OSHA’s Permit-Required Confined Space standard meet its goal?  In OSHA’s Preamble for 1910.146, published in 1993, OSHA stated: OSHA has determined that permit spaces pose significant risks to employees (62 fatalities and 12,643 injuries and illnesses annually) and estimates that compliance…...

Noise is a recognized hazard, but noise is NOT a hazard that makes a CS become a PRCS

Why is this article posted in the Permit-Required Confined Space section of the website?  Because there seem to be a large number of safety professionals that are under the impression that ANY occupational hazard can turn a confined space into a Permit-Required Confined Space.  Noise is a recognized occupational hazard – I think we can…...

Understanding Nitrogen Hazards – It is NOT a “toxic hazard” (OSHA GHS)

Last year I was attending some continuing education for my hazardous materials work.  The instructor was outstanding until he went on his tirade against Nitrogen (N2).  He was factually correct when he stated that N2 was a leading killer within confined spaces, but he went off the rails when he tried to convince me that…...

Permit-Required Confined Space Program (w/ Construction requirements)

Attached is the written program for General Industry facilities which incorporate OSHA’s newer Confined Spaces in Construction requirements.  It is my recommendation that we UPDATE our written program that was based on the older 1910.146 standard to include all the improvements in 1926.1201 – .1213.  We should also understand that even though our facility may…...

Reclassifying a PRCS to a Non-PRCS is more than just locking out energy sources!

Too many safety professionals still to this day think that to reclassify a Permit-Required Confined Space (PRCS) is simply to lock out all the energy sources that made the space a PRCS.  In August of last year, I posted a story where I asked the 30,000 members of the SAFTENG network if an enclosed palletizer…...
