PORTS AND TERMINALS 25<br />

Fire <strong>and</strong> gas-detection equipment are key to maintaining the overall safety <strong>and</strong> operation <strong>of</strong> ports/<br />

terminals. The equipment continuously monitors for abnormal situations such as fire <strong>and</strong> the release<br />

<strong>of</strong> combustible or toxic gases within the terminal/port, providing an early warning to prevent escalation<br />

<strong>of</strong> the incident <strong>and</strong> protect the process or environment. Fire <strong>and</strong> gas-detection equipment can detect<br />

early warnings <strong>of</strong> explosive <strong>and</strong> health hazards, including combustible <strong>and</strong> toxic-gas releases, thermal<br />

radiation from fires <strong>and</strong> traces <strong>of</strong> smoke. They provide audible <strong>and</strong> visual alarms to ensure that operators<br />

<strong>and</strong> personnel are informed <strong>of</strong> potentially hazardous situations, allowing for immediate actions to<br />

minimise escalation <strong>of</strong> safety incidents, protecting personnel, property <strong>and</strong> the environment.<br />

ACTIONS<br />

Technical <strong>and</strong> Management<br />

The selection <strong>and</strong> fitting <strong>of</strong> fire-detection equipment <strong>and</strong> alarm systems at a terminal or port depend<br />

on several factors including:<br />

• products being h<strong>and</strong>led;<br />

• size <strong>and</strong> quantity <strong>of</strong> the vessels/barges berthed per year;<br />

• terminal throughput;<br />

• pumping rate; <strong>and</strong><br />

• proximity to residential, commercial or other industrial properties.<br />

Before installation, the advice from manufacturers <strong>and</strong> fire-safety experts should be considered,<br />

<strong>along</strong> with a compliance check against applicable regulations.<br />

When planning a fire detection system, detectors should be selected based on the type <strong>of</strong> fires that<br />

can occur. The following should be taken into consideration:<br />

• type <strong>and</strong> quantity <strong>of</strong> fuel h<strong>and</strong>led;<br />

• possible ignition sources;<br />

• range <strong>of</strong> ambient conditions; <strong>and</strong><br />

• value <strong>of</strong> the property.<br />

Fixed combustible gas sensors should be placed in areas sensitive to hydrocarbon leaks or spills (e.g.<br />

loading arm areas, near valve manifolds <strong>and</strong> near transfer pumps) or areas that contain ignition<br />

sources. Fixed toxic-gas sensors may be installed in supply air intakes <strong>of</strong> cargo control rooms. Fire <strong>and</strong><br />

gas detection equipment should be periodically tested to ensure reliable operation.<br />

The alarm system should have the capability to automatically self test <strong>and</strong> warn <strong>of</strong> malfunctions<br />

<strong>and</strong> to raise local audible <strong>and</strong> visual alarms <strong>and</strong>, depending on the circumstances, a general alarm.<br />

It should indicate an alarm on a fire-control panel indicating the location <strong>of</strong> the activated sensor.<br />
