Annex to 4.6.2(3) Spaces shall be inspected daily... The intent of this wording is to clarify that spaces listed on the Marine Chemist Certificate do not need to be tested by the competent person unless work is being done on or in a space. For example, spaces on a certificate do not need to be tested and inspected on a weekend if no work or entry is taking place. However, nothing shall prevent a competent person from testing more frequently than the minimum NFPA-306

“Unless otherwise stated on the Certificate, all spaces and affected adjacent spaces are to be re-inspected daily or more often as necessary by the competent person … in support of work prior to entry or recommencement of work.” “In support of work” is the spin. Small Print
