A competent person will visually inspect and test each space certified as "Safe for Workers" or "Safe for Hot Work," as often as necessary to ensure that atmospheric conditions within that space is maintained within the conditions established by the certificate after the certificate has been issued. a f a competent person finds that the atmospheric condtions within a certified space fail to meet the applicable requirements work in the certified space will be stopped and may not be resumed until the space has been re -tested by a Marine Chemist and a new certificate issued. Fire Department Permit Certain cities, such as Seattle, require that a permit be obtained prior to any hot work on vessels in that city.

If the concentration of flammable vapors or gases is equal to or greaterthan 10 percent of the lower explosive limit in the space or an adjacent space where the hotwork is to be done, then the space will be labeled "NotSafefor HotWork" and ventilation shall be provided atvolumes and flow rates sufficientto ensure thatthe concentration of flammable vapors orgases is below 10 percent by volume of the lower explosive limit. The warning label maybe removed when the concentration offlammablevapors and gases are below 10 percent ofthe lowerexplosive limit. After a competent person has conducted a visual inspection and tests required, and determined a space to be safe for an employee to enter, he or she shall continue to test and visually inspect spaces as often as necessary to ensure that the required atmospheric conditions within the tested space are maintained.
