Title:

ELECTRICAL SAFETY

1.0 PURPOSE

This procedure outlines the responsibilities and activities required to ensure Quality, Health, Safety andEnvironmental (QHSE) Management responsibilities are carried out associated with the use of electricity in theworkplace.

Implementation of this procedure will ensure that all M-I SWACO (Company) personnel are aware of risksassociated with the use of electricity and electrical equipment.

2.0 SCOPE

Covers all aspects of QHSE Management associated with carrying out business activities or processes involvingthe use of electricity and electrical equipment. Covers all M-I SWACO personnel or any third party organization orpersonnel (e.g. consultants) associated with Company business activities or processes.

3.0 RESPONSIBILITIES

The local manager is responsible for ensuring the necessary resources are made available to maintain electricalsupplies and equipment in safe working order and for ensuring that only adequately trained and qualified peopleare authorized to conduct work on electrical systems and equipment.

All personnel are responsible for handling electrical systems and equipment in a safe and responsible manner, forreporting any defects noticed and for ensuring only suitably and sufficiently trained personnel conduct work onelectrical systems and equipment.

4.0 GENERAL REQUIREMENTS

M-I SWACO acknowledges that health and safety hazards may arise with the provision and use of electricity andelectrical equipment. It is the Companys intention to ensure that any risks associated with electricity such as:death or injury to persons from: electric shock, electrical burns, electrical fires, electric arcing or explosionsinitiated or caused by electricity are reduced to a minimum.

This procedure covers the normal use of equipment supplied with electrical power in use in workshops, offices,sites, warehouses and accommodation. The equipment may be fixed or portable. Risks associated with testing ormaintenance is also covered.

Any person using equipment supplied with electrical power is at risk if that equipment is incorrectly orinadequately maintained, untested or has not undergone periodic examination or maintenance. Maintenance andrepair personnel are especially at risk if the equipment they are testing or repairing is not correctly isolated from allpossible sources of electrical power. Persons not directly involved with the installation, test or repair may be

placed in danger if the correct procedure for isolation is not carried out, refer to Element 7.1.3.12 Lock Out TagOut.

Electrical hazards are associated with the following:

the fixed installation;

electrically powered tools; portable electrical appliances; and

leads, connectors and other components of electrical tools and appliances.

The following actions should eliminate or reduce the risk associated with the above hazards to an acceptablelevel. The analysis of the likelihood and severity of harm being caused by electrical equipment, taking into accountthe preventative and protective measures should be shown on the general risk assessment form. Where changestake place in any of the activities outlined above or any other hazard is identified which is not included above, anadditional risk assessment must be carried out with details of the appropriate arrangement.

Examples of activities where a specific risk assessment will be required include:

electric welding adjacent to water or other conducting liquids; use of electrical equipment in adverse weather conditions;

working on sites and in conditions where cable damage is likely, e.g. trailing leads in walkways, stairwells,being, pulled over sharp edges, or at heights where cables may be unsupported putting strain on cableclamping devices;

use of computer controlled equipment;

working near overhead and underground power lines;

portable equipment used outside;

testing, maintenance and the provision of electrical services in flammable risk areas or explosivesmagazines;

provision and/or maintenance of electrical services in areas adjacent to bulk or bottled gas storage areas;

any requirement for working on electrically live equipment; and provision of electrical services in buildings during the construction phase.

4.1 Planning and OrganizingThe site manager will ensure that any electrically powered equipment, service or portable apparatus in use ontheir premises is of an approved type which meets the requirements of appropriate countrys legislation andstandards. Where no specific country legislation exists, as a minimum, all electrical equipment used on site mustbe inspected and approved by suitably qualified person prior to putting into service. All electrical equipment shallbe tested and maintained to a safe standard by qualified personnel in accordance with the control measuresoutlined below.

1. The fixed systems will be installed to appropriate countries standards and legislative requirements, and

will be maintained and tested at intervals as specified by the manufacturer.2. Portable apparatus will be maintained and tested at intervals specified by the manufacturer. Equipment

requiring to be operated outdoors or in a workshop environment, where possible, should be suitable foruse on a 110 volt supply and should be fed from a double wound, center tapped to earth transformer.Thus ensuring that the maximum voltage with reference to earth is 55 volts. Alternatively a residualcurrent device, suitably rated circuit breaker or similar, country specific, fault trip device should be usedto minimize the risk of electrical shock.

3. Work to be completed on or near live equipment will require a risk assessment to be completed prior tocommencing with the work. This should justify both that the work cannot be carried out while theequipment is dead, PPE required i.e. rubber gauntlets, rubber matting, insulated hand tools, and that itis safe to carry out the work while the equipment is live.

4. All maintenance and testing of electrical plant and portable equipment is to be carried out by employees

or contractors who have been trained and certified as competent.5. All power supplies will be fully isolated, labeled and locked in the off position while work is in progress

on the circuit or system. Where electrical isolators do not have provision for locking out circuit, breakeror fuses should be switched off or pulled and the circuit conductors disconnected to ensure suppliescannot be switched on accidentally.

6. Battery power banks will be of an approved construction, fitted with safety isolators and provided withadequate ventilation extraction.

7. Suitable personal protective equipment (PPE) and safety equipment will be provided.

5.0 TRAINING

The site manager will ensure that sufficient persons have been trained to carry out maintenance and testing ofequipment and services provided for use on M-I SWACO premises. Where contractors are to be used, only thosewith the required qualifications will be hired to complete electrical work.

The site manager will ensure that a record of training is maintained on site. This will list the competence level of allelectrically trained staff, together with details of specialist courses completed by staff. Where contractors' orsubcontractors' staff are used on site, copies of their training records will be held by the site manager.

All persons required to install, maintain, repair or test electrical equipment, whether employees or contractors'staff, shall have received training to ensure they have the competence to carry out the work in accordance withany current country legislative requirements and standards. Any person required to operate equipment poweredfrom electrical sources will be given instruction and practical training in the use of the equipment.

All equipment in use within the Company's premises (or on client's sites when being used by the Company'semployees as part of a contract) is at all times safe to use, tested and maintained in accordance with themaintenance schedule. Records of all electrical systems on site and all portable plant, together with themanufacturer's specification and data on when the equipment was first used, tested "on site" and maintained, is tobe kept up to date by the appropriate personnel.

The site manager will ensure that PPE and safety equipment is used when needed to provide the required degreeof protection to those working on electrical equipment and systems, and others in the area or who may be affectedby the work.

A permit to work safety system is to be used where work is to be carried out: on equipment in hazardous areas;

in confined spaces;

at height;

where "upstream or downstream" activities and operations require safety consideration prior to workingon equipment; or

where equipment being worked on is "dead" but is located adjacent to live "bus bars".
