CONFINED SPACE ENTRY POLICY ABOARD MERCHANT VESSELS

Pump Room Hazard Incident

Current guidance for confined space entry is in the form of recommended Safe Work Practices (SWP’s) contained in the Marine Safety Manual (MSM), Volume I, Chapter 10. Although much of the guidance in the MSM has been modified over the years and has been incorporated into SWP’s in the current version, the general policy of requiring an NFPA Certificated Marine Chemist to test and certify confined spaces prior to entry by Coast Guard personnel has not changed.
