The alternate entry procedures at 1910.146(c)(5) can be used when the only hazard in a permit space is an atmospheric hazard that can be controlled through continuous forced air ventilation. If the employer follows the alternate entry procedures, they do not need to comply with paragraphs (d) through (f) and (h) through (k). If the space has other hazards, such as an internal configuration that could trap an entrant or mechanical equipment that needs to be locked out, then the alternate entry procedures would not apply.
