Communication and Fire Alarm Equipment Tag in the plant.
1.1
In an existing plant the contractor shall assign new equipment Tag numbers shall be
as per respective affiliate numbering procedure.
1.2 SABIC shall approve the equipment Tag numbers that are assigned by the
CONTRACTOR(s).
1.3 All equipment within a Vendor supplied package shall also be assigned equipment
Tag numbers in accordance with this procedure.
