1 Access routes to the controls for closure of
the ventilation system "permit a rapid shutdown" and adequately "take
into account the weather and sea conditions" if the routes:
-
.1 are clearly marked and at least 600 mm clear
width;
-
.2 are provided with a single handrail or wire
rope lifeline not less than 10 mm in diameter, supported by stanchions
not more than 10 m apart in way of any route which involves traversing
a deck exposed to weather; and
-
.3 are fitted with appropriate means of access
(such as ladders or steps) to the closing devices of ventilators located
in high positions (i.e. 1.8 m and above).
2 Alternatively, remote closing and position indicator
arrangements from the bridge or a fire control station for those ventilator
closures is acceptable.
