Hazardous Materials

As with my NH3 article, I wanted to verify and document the same scenario for scrubbing 1 pound of Cl2 with 50% Sodium Hydroxide (NaOH). Here is what Gemini+ had to say… When Chlorine (Cl2) gas is safely scrubbed with Sodium Hydroxide (NaOH), the reaction produces sodium hypochlorite (bleach), sodium chloride (salt), and water. Bottom…...

So I asked Google Gemni + to calculate the pressure wave in a room that is 40′ X 40′ X 20′ tall with the catastrophic failure of a 1-ton chlorine cylinder. In a 32,000 ft3 room, we must determine the volume of gas released during the “instantaneous flash” and the resulting internal static overpressure…. Membership...

DISCLAIMER: This is a “cheat sheet” for safety professionals to get a general idea of the “safe distances.” ALWAYS refer to ASME PCC-2, Mandatory Appendix 501-III) for the exact distance. Just understand, ALL pneumatic pressure testing REQUIRES a “safe distance”. According to ASME PCC-2, Mandatory Appendix 501-III, determining safe distances for pressure testing—specifically, pneumatic testing—requires…...

Under Cal/OSHA’s Process Safety Management (PSM) standards (specifically Title 8 §5189.1 for refineries and §5110.16 for other facilities), the Hierarchy of Hazard Control Analysis (HCA) is a formal, documented requirement that goes significantly beyond the traditional OSHA “inverted pyramid.” While standard safety protocols often treat the hierarchy as a suggestion, Cal/OSHA makes it a mandatory…...
