in a location which will not impede movement within the marine craft.

NOTE: See Clause 6.3.3 for compartment requirements.

6.3.2.4 Cylinders to be upright
A cylinder shall be installed upright with the valve uppermost.
NOTE: This is to ensure the inlet to the safety valve always remains in the vapour space
clear of the liquid content of the cylinder.

6.3.2.5 Securing of cylinder

Licensed to LUU MINH LUAN on 26 Feb 2002. Single user licence only. Storage, distribution or use on network prohibited.

A cylinder or cylinder carrier shall be rigidly secured to the structure of the marine
craft so that its fastenings are capable of withstanding a steadily applied load equal
to four-times the weight of the filled cylinder. The cylinder mounting method is to be
capable of withstanding this applied load from any direction.

6.3.3 Cylinder in a compartment
6.3.3.1 Identification of cylinder compartment
A cylinder compartment shall be identified in accordance with the requirements of
Clause 6.2.3.2.

6.3.3.2 Requirements for a cylinder compartment
A cylinder compartment shall comply with the following:
(a)

Not be accessible from an enclosed section of the marine craft.

(b)

Be designed to –
(i)

house cylinders and their associated equipment only; and

(ii)

allow the cylinder to be positioned in the compartment without
obstructing the drain in (g); and

(iii)

permit easy removal of the cylinder(s) and the operation of the cylinder
valve(s).
NOTE: Consideration should be given to the location of the associated
equipment when determining the compartment size to enable requirement (iii)
to be satisfied.

(c)

Be constructed of material that is water and corrosion resistant.

(d)

Be capable of securing the cylinder(s) when full.
NOTE: For requirements of securing method see Clauses 6.2.2.6 and 6.2.2.7.

(e)

Be sealed to prevent gas vapour from entering any enclosed section of the
marine craft.

(f)

The access door or opening shall be openable without the use of tools.

(g)

Where the access opening into the compartment is other than at the top, a
lower vertical return or lip of at least 100 mm is to be provided along the full
length of the opening.

(iv)

where terminating in a self-draining cockpit, the cockpit drain shall
provide unrestricted drainage from the cockpit area.
NOTES:
1 A cockpit which is drained by means of a drainpipe that could under any
condition retain water would not satisfy the requirement of (iv).
2 See also Figure 6.2.

6.3.4 Cylinder regulator
6.3.4.1 Connection of cylinder regulator to the piping system
Where a cylinder regulator is not rigidly secured to the marine craft, but is

test pressure and test duration of 10 minutes.

(b)

With appliances and regulators connected, a pressure test in accordance with
Appendix E.

6.3.6 Appliances
NOTE: Where a cooking appliance is to be installed consideration should be given to the
fitting of fiddle rails and pot holders to the appliance to prevent unintentional movement

location where it is intended to be used or likely to be used is deemed to be installed.
2 An appliance operating at a pressure exceeding 2.75 kPa on commercial vessels may
be exempted from requirement (b) by the Authority.
3 In respect to space heaters see Clause 6.3.6.3.

6.3.6.2 Restriction on installation of an appliance on a petrol-fuelled craft
Where an appliance with a continuously burning flame is to be installed below the
upper deck of a petrol-fuelled craft, the appliance shall be installed so the air intake
to the continuously burning flame is at least 600 mm above the deck on which the
appliance is to be mounted.
NOTE: This does not apply where there is no possibility of petrol vapour entering the
space where the appliance is to be mounted.

6.3.6.3 Restriction on installation of space heaters
A space heater, other than of a room-sealed type, shall not be installed on a marine
craft.
NOTE: For a space heater installation on a house-boat, the Authority should be
contacted, as a flueless space heater may be permitted in the living area of the houseboat where the area can be isolated from the sleeping area. The heater needs to be fitted
with a flame safeguard, tilt safety switch and oxygen depletion device. The maximum gas
consumption of the heater is not to exceed 0.2 MJ/h for each cubic metre of room
volume.
