SAFETY MANAGEMENT

VHF radio telephone sets may only operate in the internationally agreed wave
bands.
under which the installation may be used safely.่านั้น---
Equipment should be well maintained. Damaged units, even though they may be
capable of operation, should not be used.

42. The ship’s main radio transmitter aerials are earthed and radars are switched
off.
The ship’s main radio station should not be used during the ship’s stay in port,
except for receiving purposes. The main transmitting aerials should be
disconnected and earthed.
Satellite communications equipment may be used normally, unless advised
otherwise.

The ship’s radar installation should not be used unless the Master, in
consultation with the Terminal Representative, has established the conditions

43. Electric cables to portable electrical equipment within the hazardous area are
disconnected from power.

The use of portable electrical equipment on wandering leads should be
prohibited in hazardous zones during cargo operations, and the equipment
preferably removed from the hazardous zone.
ึ
Telephone cables in use in the ship/shore communication system should
preferably be routed outside the hazardous zone. Wherever this is not feasible,
the cable should be so positioned and protected that no danger arises from its
use.

44. Window type air conditioning units are disconnected.

Window type air conditioning units should be disconnected from their power

45. Positive pressure is being maintained inside the accommodation, and air
conditioning intakes, which may permit the entry of cargo vapours, are
closed.
A positive pressure should, when possible, be maintained inside the
accommodation, and procedures or systems should be in place to prevent
flammable or toxic vapours from entering accommodation spaces. This can be
achieved by air conditioning or similar systems, which draw clean air from
non-hazardous locations.

Air conditioning systems should not be operated on 100% recirculation.

46. Measures have been taken to ensure sufficient mechanical ventilation in the
pumproom.
Pumprooms should be mechanically ventilated and the ventilation system, which
should maintain a safe atmosphere throughout the pumproom, should be kept
running throughout cargo handling operations. The gas detection system, if
fitted, should be functioning correctly.

47. There is provision for an emergency escape.
In addition to the means of access referred to in Question 1, a safe and quick
emergency escape route should be available both on board and ashore. On
board the ship, it may consist of a lifeboat ready for immediate use, preferably
at the after end of the ship, and clear of the moorings.
