PRE-INSPECTION PROCEDURES Determine Authorization to Certify Is This a Liability Issue? Notification Requirements
CERTIFICATION & LIABILITY l. The Shipboard GFE Can Certify a Space for any Crewmember • CO’s Authorization is Required for IDLH Spaces – O 2<19. 5% or > 22% – Explosivity > 10% of LEL – Toxics above PEL – Sewage, Fuel, or Oil Tanks
Page C-26 NSTM 074 VOL 3 “SAMPLE GAS FREE ENGINEERING PROCEDURAL WORKING GUIDE” l Use as a guide so you don’t forget anything! 2 Pre-Inspection Procedures 2 Closed Compartment Opening & Testing Procedures 2 Post-Inspection Procedures
CLOSED COMPARTMENT OPENING REQUEST FORM l Helps You Organize Your Time l Prioritize Your Workload l Provides Planning For: – Safety Observers – Equipment Movement – Space & Equipment Tag Outs l TALK l TO THESE PEOPLE NSTM 074 V 3 Appeddix C 13, 29 Closed Compartment Opening Request Form
