ABBREVIATIONS AND ACRONYMS The abbreviations, acronyms and definitions used in this document shall have the following meaning: Approving (AA)

Authority

The person authorised by the PETRONAS Carigali to approve and issue PETI Certificate Fitness (PCF) in the area concerned. He is usually the Approving Authority for Permit To Work system of the facility.

Appointed (AP)

Person

The person trained for certain electrical duties (e.g. isolation/de-isolation of electrical equipment, synchronising, etc.) and has sufficient technical knowledge and experience to enable him to avoid danger. He is a Competent Person with lowerCertificate of Competency(CoC) but authorized by Management to perform certain tasks that usually only carried-out by a person who has appropriate CoC. Example: A facility that is having a low voltage Synchronous generator requires an A4 chargemanto operate; however, due to unavailability an A4 chargeman, an AO chargeman can be authorizedby the management to operate the generator provided that he has proved that he has the knowledge and skill to perform such duty. Other example, a BOchargemanauthorizedas an AP for B4chargeman.

Authorized Competent

For the purpose of this guideline, ACP is defined as the person registered with Energy Commission or equivalentlocal authority of host countryand authorised by Management. He has sufficient technical knowledge and experience to enable him to avoid danger and who can have authority delegated to him, according to his knowledge and experience to carry out operations in power systems and work on electrical equipment. He has the authority to issue and cancel Electrical Isolation Certificate and Limit of Electrical Access on Electrical Equipment/System.

Person (ACP)

Authorised Inspector

The Authorised Inspector is either ACP/AP or the appointed personnel to inspect portable equipment to determine that they are fit for use and safe for mobilisation/delivery to site.

Class I

Equipment having one or more parts with functional insulation only and required to be earthed.

Class II

Mains-operated or transformer-operated equipment, which has either "all-insulated" or has double or reinforced insulation, in accordance to IEC 60536. It is not intended to be earthed.


PRELIMINARY Page vi


WW ALL S 04 032 Rev.0, Dec 2012

Class II equipment is subdivided as follows: Class IIA  Equipment that is "all-insulated". This means that all the metallic parts are enclosed with durable and continuous insulated enclosure. It need not be double insulated. 

Class IIB Equipment that is "double-insulated". It has not only the normal basic insulation necessary for its proper functioning but also a supplementary insulation for safeguarding against shock if the basic insulation breaks down. In cases where there is not enough space for separate insulation, a single "reinforced" insulation electrically equivalent to double insulation may sometimes be accepted.

Class III

Equipment designed for connection only to Extra Low Voltage (ELV). This means a voltage not more than 50V AC, but in practice limited to 42V. The main supply is obtained by means of a safety isolating transformer. No earth connection is provided.

Company

Refers to PETRONAS CarigaliSdn Bhd.

Confined spaces

conductive

Confined spaces where it is likely that a person will be in contact with conductive parts at two or more points simultaneously. Example of Confined conductive spaces such as in boiler, vats, tanks(inclusive above floating roof tank), pits, pipes, ducts, flues, chimneys, silos, containers, pressure vessels, underground sewers, wet or dry wells, shafts, trenches, tunnelsor other similar enclosed or partially enclosed structures,

Equipment Checklist

The checklists consist of key inspection elements for a particular type of equipment.

Ex Equipment

Equipment that is certified for used in hazardous classified area equipment.

Extra Low Voltage (ELV)

A system which is not exceeding 50Vr.m.sor below 120V DC, whether between conductors or to earth.

Hand-held Equipment

Portable equipment that is continuously grasped in the hand during normal use. Example of hand heldequipment are grinder, portable inspection lamp etc. On the other hand, example of nonhand held are electrical equipment such floodlight, portable junction box, mobile generator etc.

Electrical

PETI PETI Certificate Fitness (PCF)

to be used. Portableelectrical equipment

Portable electricalequipment iseither hand held or nonhand held equipment. For hand held, the equipment grasp in hand during normal use.

Reduced Low Voltage System (RVS)

A system in which the nominal phase-to-phase voltage does not exceed 110 volts and the nominal phase to earth voltage does not exceed 63.5 volts.

Safety-Extra Voltage (SELV)

An extra-low voltage system which is electrically separated from earth and from other systems that a single fault cannot give rise to the risk of electric shock, in accordance to IEC 60742 (SELV System).

Low

Temporary Electrical Installation

Temporary Electrical Installation in the context of this guideline is installation that do not form part of the plant’s permanent or fixed installation. Examples of Temporary Electrical Installation are temporary generator, distribution board, pumps, welding machine and electric air compressor.

1.1

Purpose

WW ALL S 04 032 Rev.0, Dec 2012

This guideline defines the requirements for portable electrical equipment and temporary installation with regards to proper selection of equipment and tool, inspection prior to mobilization to worksite, site certification and periodic inspection/recertification throughout the duration of the equipment being used at worksite. The requirements are specified as below:

1.2

(1)

The equipment is suitable and safe for use in the intended worksite or classified hazardous area;

(2)

All equipment is in a good condition and well maintained;

(3)

The safety features such as guards, emergency stop button, etc. are in place and in good operating condition;

(4)

Only inspected portable electrical equipment and temporary electrical installation shall be used;

(5)

The integrity of the equipment is continuously assured throughout the duration of its use; and

(6)

The inspected and approved electrical equipment is affixed with inspection sticker accordingly.

Scope The requirements defined in this guideline shall be applicable to portable electrical powered equipment and electrical generating equipment used throughout PETRONAS Carigali facilities/worksites, including Contractors and Sub-Contractors. For non-electrical equipment, the requirements defined in PETRONAS Carigali Equipment Passport System shall be complied with.

Note:

Electrical equipment or appliances in office such as computers, televisions, photo copiers, electric kettles, coffee machines, etc. Battery operated tools and torch lights are exempted from the requirement of inspection and certification.
