period of 8 hours and for at least 12 hours if the supply is not reasonably
reliable.

In auxiliary and remote station systems where trouble signals from the
loss of local operating power might not be transmitted to the receiving
station, a 60 hour emergency power supply capacity is usually required in
order that the emergency supply can operate the entire system if the
power is cut over a weekend.

Handling Crude Oil and Petroleum Products

19.4.1 General

transferring crude oil and flammable hydrocarbon liquids will depend on a
number of factors that include the following:

The commodities or products transferred.
Tanker size and number berthed per year.
ึ
Pumping rates.
The proximity of hazardous equipment with respect to other equipment
or hazards, i.e. equipment spacing, electrical area classification.
The proximity of tankers to the terminal and to hazardous terminal

equipment.
The proximity of the terminal to residential, commercial or other
industrial properties.

The installation of emergency isolation valves.
The number and nature of fixed fire extinguishing systems that are
connected to detection and alarm systems.

Whether the terminal is continuously manned or periodically
unmanned.
งานห้อ Proximity to any outside emergency response units, and their capacity,
The ability of the emergency response unit at the terminal or within

the terminal’s organisation to provide a timely and effective response.
availability and time of response.

Requirements imposed by local regulatory bodies.
The desired degree of protection beyond regulatory requirements.
The degree of effective protection that a particular manufacturer’s
detection and alarm system offers.

The alarm system should have the capability to raise local audible and
visual alarms and possibly a general alarm if the terminal is manned and
depending upon local circumstances. It should indicate an alarm at a
continuously attended central fire control panel showing the location of
the activated detection and fire extinguishing system. Where fixed gas
detection equipment is installed or the detection system covers more than
a single detection zone, the panel should indicate the location of the
activated gas detector.
