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 […]

UN’s proposal for modification of the classification criteria and hazard communication for flammable gases

When bollards look good, but fail miserably

Bollards – a safety engineer’s best friend and a facility engineer’s worst nightmare.  I am not quite sure how we lost our way in such a simple design for such a significant safeguard.  But the International Fire Code (IFC) since the early 1990’s when I began using it has remained consistent in the design of
