Current through Register Vol. 24-14, July 15, 2024
(1) Preventing hazardous materials from
			 entering. Pipelines that could carry hazardous materials into spaces that have
			 been certified "safe for workers" or "safe for hot work" must be disconnected,
			 blanked off, or otherwise blocked by a positive method to prevent hazardous
			 materials from being discharged into the space.
(2) Alteration of existing conditions. When a
			 change that could alter conditions within a tested confined or enclosed space
			 or other dangerous atmosphere occurs, work in the affected space or area must
			 be stopped. Work may not be resumed until the affected space or area is
			 visually inspected and retested and found to comply with WAC
			 296-304-02003,
			 296-304-02005, and
			 296-304-02007, as applicable.
Note to (2):
Examples of changes that would warrant the stoppage of
						  work include: The opening of manholes or other closures or the adjusting of a
						  valve regulating the flow of hazardous materials.
(3)
			 Tests to maintain the conditions of a marine chemist's or Coast Guard
			 authorized person's certificates. A competent person must 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 are
			 maintained within the conditions established by the certificate after the
			 certificate has been issued.
(4)
			 Change in the conditions of a marine chemist's or Coast Guard authorized
			 person's certificate. If a competent person finds that the atmospheric
			 conditions within a certified space fail to meet the applicable requirements of
			 WAC 296-304-02003,
			 296-304-02005, and
			 296-304-02007, work in the
			 certified space must be stopped and may not be resumed until the space has been
			 retested by a marine chemist or Coast Guard authorized person and a new
			 certificate issued in accordance with WAC
			 296-304-02007(1).
(5) Tests to maintain a competent person's
			 findings. After a competent person has conducted a visual inspection and tests
			 required in WAC
			 296-304-02003,
			 296-304-02005, and
			 296-304-02007 and determined a
			 space to be safe for an employee to enter, he or she must continue to test and
			 visually inspect spaces as often as necessary to ensure that the required
			 atmospheric conditions within the tested space are maintained.
(6) Changes in conditions determined by
			 competent person's findings. After the competent person has determined
			 initially that a space is safe for an employee to enter and he or she finds
			 subsequently that the conditions within the tested space fail to meet the
			 requirements of WAC
			 296-304-02003,
			 296-304-02005, and
			 296-304-02007, as applicable,
			 work must be stopped until the conditions in the tested space are corrected to
			 comply with WAC
			 296-304-02003,
			 296-304-02005, and
			 296-304-02007, as
			 applicable.
