New regulation 20-1 – Requirements for vehicle
carriers carrying motor vehicles with compressed hydrogen or natural
gas in their tanks for their own propulsion as cargo
15 The following new regulation 20-1 is added
after regulation 20:
"Regulation 20-1 – Requirements for vehicle
carriers carrying motor vehicles with compressed hydrogen or natural
gas in their tanks for their own propulsion as cargo
The purpose of this regulation is to provide additional
safety measures in order to address the fire safety objectives of
this chapter for vehicle carriers with vehicle and ro-ro spaces intended
for carriage of motor vehicles with compressed hydrogen or compressed
natural gas in their tanks for their own propulsion as cargo.
2.1 In addition to complying with the requirements
of regulation 20, as appropriate, vehicle spaces of vehicle carriers
constructed on or after 1 January 2016 intended for the carriage of
motor vehicles with compressed hydrogen or compressed natural gas
in their tanks for their own propulsion as cargo shall comply with
the requirements in paragraphs 3 to 5 of this regulation.
2.2 In addition to complying with the requirements
of regulation 20, as appropriate, vehicle carriers constructed before
1 January 2016, including those constructed before 1 July 2012footnote, shall comply with the requirements in
paragraph 5 of this regulation.

Requirements for spaces intended
for carriage of motor vehicles with compressed natural gas in their
tanks for their own propulsion as cargo
3.1
Electrical equipment and
wiring
All electrical equipment and wiring shall be of a certified
safe type for use in an explosive methane and air mixturefootnote.
3.2
Ventilation arrangement
3.2.1 Electrical equipment and wiring, if installed
in any ventilation duct, shall be of a certified safe type for use
in explosive methane and air mixtures.
3.2.2 The fans shall be such as to avoid the possibility

Requirements for spaces intended
for carriage of motor vehicles with compressed hydrogen in their tanks
for their own propulsion as cargo
4.1
Electrical equipment and
wiring
All electrical equipment and wiring shall be of a certified
safe type for use in an explosive hydrogen and air mixturefootnote.
4.2
Ventilation arrangement
4.2.1 Electrical equipment and wiring, if installed
in any ventilation duct, shall be of a certified safe type for use
in explosive hydrogen and air mixtures and the outlet from any exhaust
duct shall be sited in a safe position, having regard to other possible
sources of ignition.
4.2.2The fans shall be designed such as to avoid the possibility
of ignition of hydrogen and air mixtures. Suitable wire mesh guards
shall be fitted over inlet and outlet ventilation openings.
4.3
Other ignition sources
Other equipment which may constitute a source of ignition
of hydrogen and air mixtures shall not be permitted.
When a vehicle carrier carries as cargo one or more motor
vehicles with either compressed hydrogen or compressed natural gas
in their tanks for their own propulsion, at least two portable gas
detectors shall be provided. Such detectors shall be suitable for
the detection of the gas fuel and be of a certified safe type for
use in the explosive gas and air mixture."
