This safety alert is very much applicable to us in the CPI. Anaerobic bacteria reside in ETP's.
This safety alert shares important information related to a unique, not very well known and potentially
deadly hazard that recently developed on a vessel involving the formation of dangerous levels of
Hydrogen Sulfide (H2S)1 gas within a waste oil tank. This was determined to be due to the use of
biodegradable cleaners and the chemical reactions and resultant H2S byproduct involved in breaking
down oils in an anaerobic (low oxygen) environment like that found in a full slop tank. In this case,
vessel officers had detected significant H2S concentrations (>200 PPM) in the vessel’s engine room
bilge holding tank.The cleaner provided micro-nutrients to the waste water thus causing the bacteria to thrive resulting in increased rates of H2S production.
