The environment, organization, economics, capabilities, technology, and regulatory context all change over time. This backdrop of continuous systemic change ensures that hazards and how they are managed are constantly changing. Progress on safety concerns anticipating how these kinds of changes will create new vulnerabilities and paths to failure even as they provide benefits on other scores. The...

Now, I’m 100% certain that Mr. Gogh did not have the safety profession in mind when he said the following, but it could not be more true in the context of our profession. Few professions need passion like that of the safety profession.

Chlorine dioxide (ClO2) gas is unstable and decomposes, sometimes violently, into Cl2 and O2 (with a 50% increase in gas volume). When storing chlorine dioxide (ClO2), it is commonly kept in CHILLED WATER because its solubility in water significantly increases at lower temperatures, making it more stable and allowing for higher concentrations to be safely stored; essentially, cold water helps to preserve...

You have to wonder if the creator(s) knew exactly what they were doing or if they were totally clueless. But what do you see when you look at the Emergency Exit map Of The Marriott Marquis San Diego. Thanks to ___________ (who wished to remain anonymous – why I am not sure) for their contribution.
