Chemical Process Safety (PSM/RMP)

Line Break/Equipment Opening GONE BAD (185F water)

Another example shows us that serious hazards can be found OUTSIDE of chemical processes, and applying the Line Break/Equipment Opening Procedure and Permit to these hazards could go a long way in controlling these recognized hazards. DEFINING and QUANTIFYING “hazardous energy” sources is STEP 1 in ensuring the process/system can be safely opened. Step 2 […]
