BS EN 60079 Hazardous Area Electrical Inspections

BS EN 60079 Hazardous Area Electrical Inspections

Inglewood Engineering are leading experts in Hazardous Area Electrical Inspections and can advise you on the protocols and regime that are sufficient for your installation.
The British Standard BS EN 60079 Part 18 covers Inspections and Maintenance of Electrical Installations in Hazardous Areas. In order to comply with the standard a hazardous area inspection programme must be established. The employer must ensure that a competent body independent of the maintenance programme completes periodic inspections.
The programme is the basis for protecting against ignition sources in hazardous areas. It demonstrates good intent and is a core defence should one be needed. Within that regime every single ignition source must be accounted for, and inspection protocols put in place to demonstrate due diligence.
There are a number of inspection protocols detailed in BS EN 60079 Part 18. It refers to four inspection types − Initial, Periodic, Sample and Special (for movable apparatus); three inspections grades Visual, Close and Detailed; and a variety of inspection schedules for flameproof, intrinsically safe etc.
DSEAR Training

DSEAR Training

DSEAR Training courses are offered by Inglewood Engineering. Our bespoke training courses are designed to ensure that employers meet their duties under Regulation 9 of DSEAR.
Regulation 9 states that the employer shall provide his employees with:-
’suitable and sufficient information, instruction and training on the appropriate precautions and actions to be taken by the employee in order to safeguard himself and other employees at the workplace’
Our DSEAR training modules place more emphasis on the specific needs of the workplace. We tailor these courses to suit the particular requirements of the participants. For example, technicians are typically more interested in the installation requirements of BS EN 60079 Part 14, whilst engineers would be more interested in the hazardous area design considerations.
For further information on how we can help to train your employees please use our Contact Us form or call 01625 410100.
Area Classification & Risk Assessment

Area Classification & Risk Assessment

Area Classification and Risk Assessment are both areas in which Inglewood Engineering is highly experienced, with over 35 years helping clients gain DSEAR / ATEX compliance.
Our purpose is to reduce the extent of the classified areas and eliminate them if possible. We advise on ventilation, housekeeping, handling, etc where it makes a difference.
Regulation 5 of DSEAR requires that where a dangerous substance is or is liable to be present at the workplace, the employer shall make a suitable and sufficient assessment of the risks to his employees which arise from that substance.
Part of Regulation 7 of DSEAR requires that the employer classifies places at the workplace where an explosive atmosphere may occur into hazardous or non-hazardous places i.e. a hazardous area study must be completed.
It is vital that an accurate area classification study is completed. For instance, it is undeniably dangerous if an area is classified safe when it is actually hazardous. Much less appreciated are the consequences of getting it wrong the other way. An area that is over-classified will drain profits from your company for as long as it remains so; initially in the form of an overly expensive installation, thereafter in costly maintenance and inspection.
We classify areas in line with the harmonized standard BS EN 60079-10, also with the model code of practice if there is a connection with a particular industry e.g. Energy Institute EI15, Institute of Gas Engineers IGE SR25 etc.
A formal report is provided for your records along with the area classification drawings and supporting calculations that go with it.
DSEAR Services

DSEAR Services

Inglewood Engineering cover the full range of DSEAR Services. If you are unsure what to do and how to proceed we will talk you through hazardous area compliance steps and tell you what you need to do to make your plant compliant.
Should you need specific assistance our experts will help you determine the hazard level by guiding you through the formalities of Risk Assessment and Area Classification. Our engineers will check that your plant is suitably protected against ignition sources in hazardous areas. Our engineers will also address any issues that may arise and offer remedial design solutions.
We also advise on work place training and the establishment of an ongoing DSEAR regime to demonstrate continuing compliance. Should you need support we can represent you in discussions with the HSE.
Our overall purpose is to ensure that you are able to achieve and demonstrate compliance with the relevant DSEAR and BS EN 60079 codes of practice. We do this in the most expeditious way by providing practical advice and support, so that you are not left with a list of further problems following our intervention. Subsequently you can face up to any regulatory scrutiny with confidence.
Hazardous Area Compliance

Hazardous Area Compliance

Hazardous area compliance services have been provided by Inglewood Engineering since the early 80s, long before DSEAR came into force.
During this time we have built up an enviable client list of blue chip national and international companies that employ us for our specialist knowledge in hazardous areas (now regulated by DSEAR). Due to the variety and breadth of that list we have an experienced workforce that’s ideally suited to advising individual clients as to their industry’s best practice.
Our experience pre-dates DSEAR and the current harmonised standards by many years and by a number of previous standards. A lot of our work is still on sites that were built pre-ATEX, and our knowledge enables us to cut through the legacy that typifies older installations. We offer pragmatic solutions to DSEAR non-conformances, from straightforward advice to expert redesign.
Proof of competency is a basic requirement, and to this end we ensure our engineers hold a recognised certificate of such, notably by way of the Comp’Ex and IECEx accreditations.
Post Inspection Support Services

Post Inspection Support Services

Inglewood Engineering’s aim is to ensure you achieve full compliance. And the inspection process is only part of the answer. It is designed to seek out dangerous deteriorations in the way ignition sources are protected. Non-conformances, come in many shapes and sizes.
We advocate using your own staff to sort things out where possible; the gains are more likely to become embedded. Sometimes though even your control/electrical engineers will be put to the test and you will need to call on expert help.
In this respect our engineering credentials are second to none. We are professional engineers by qualification and training, and have spent most of our working lives designing control, electrical and instrument installations in hazardous areas. We know what constitutes compliance and we know what has to be done to achieve it.
Static Earthing Compliance

Static Earthing Compliance

Inglewood Engineering’s service covers the full range of activities depending on your static earthing status and needs.
If you are unsure what your position is we will audit your installation and make recommendations based on the code of practice. We can advise and assist with the scheduling of static earth bond tests for fixed and portable equipment, and help you set up a periodic inspection and testing regime. Inglewood Engineering are proficient practitioners and have the necessary certified test equipment to validate your static earth systems out on the plant in hazardous areas.
The Code of Practice for the avoidance of hazards due to static electricity is PD CLC/TR 60079-32-1:2015.
The accumulation of electrostatic charge, on equipment or personnel, can give rise to all sorts of problems in a wide range of premises. A static discharge can be the source of an ignition and explosion. So wherever DSEAR applies static must be brought under control, in chemicals, pharmaceuticals, petroleum and food processing industries etc.
The safe management of static requires an understanding of both the physics and the engineering of the actual circumstances. Earthing and bonding typically play a role in charge suppression but a misunderstanding of the process can lead to questionable results. Often there is inherent equalization of potential via the building structure and additional bonding is unnecessary. This is not the case where there are non-conducting structural components and dedicated bonds will need to be considered, or other anti static mechanisms.
Non-Electrical Equipment Risk Assessments

Non-Electrical Equipment Risk Assessments

The ATEX Equipment directive 2014/34/EU gives constructional requirements for non-electrical equipment and the ATEX Worker Protection Directive requires non-electrical equipment already installed to be assessed for its ignition capability.
Typical examples of existing non-electrical equipment that require risk assessment are solenoid valves, pumps, conveyor belts, hoists, gearboxes, brakes etc.
Inglewood complete the site audit, inspection work and risk assessment reports to ensure the client Dutyholder meets his compliance duties in respect of non-electrical equipment.
The risk assessment process takes into account the nature of the zone that the equipment is positioned in, the properties of the dangerous substance, risk of ignition due to the type of non-electrical equipment and the guidance given in standards.
The equipment manufacturers’ technical specifications, drawings, operating information and any associated maintenance records (including records of any failures relating to the equipment concerned) are reviewed as part of the risk assessment.
Design / Engineering in Hazardous Areas

Design / Engineering in Hazardous Areas

Inglewood Engineering have many years experience of electrical design and engineering in hazardous areas. All our work is overseen and signed off by a Chartered Electrical Engineer. The same oversight applies whether it’s a single piece of equipment or an entirely new installation.
Our expertise has proved invaluable in the early stages of new builds, at a time when expensive mistakes can be avoided. It also comes to the fore when engineering solutions to problems that arise in existing installations.
Regular inspections of existing installations are a means of highlighting any irregularities. Often the non-conformances that come to light during an inspection are minor and simple to rectify. Sometimes equipment that at first sight is unsuitable may pass the risk assessment that comes from the Essential Safety and Health Requirements, and be permitted to remain in situ. But where non-conformances are found that cannot be justified with an equipment risk assessment or rectified by a simple remedial action, we will advise on equipment replacement or redesign that part of the installation, as appropriate.
Intrinsically Safe Descriptive System Documents

Intrinsically Safe Descriptive System Documents

The basis of protection in the case of intrinsically safe systems is the limitation of energy into the hazardous area. A document detailing permissible energy levels in the system is an essential requirement. It enables you in the first instance to prove the protection method, and in the event of modifications is a reminder of the safety restrictions.
An Intrinsically Safe Descriptive System Document demonstrates compliance by proving that the energy limiting device, the barrier, is compatible with the field device in terms of power, capacitance and inductance values.
These are documents that are often hard to come by, particularly in older establishments. In keeping with their importance it is necessary at times for us to rewrite them using information gathered from the installation itself.
Explosion Protection Document

Explosion Protection Document

In order to be compliant with the ATEX 137 directive, an explosion protection document (EPD) must be created and kept up to date throughout the life cycle of the associated plant and equipment. Notably DSEAR makes no mention of the term EPD but the requirement for up to date information is very much a part of the UK regulation and an EPD certainly fits the need.
Article 8 of ATEX 137 details the exact requirements of the EPD. Its completion follows on from the risk assessment and area classification actions.
A number of companies in the UK have gone down the EPD route and drawn on our skills and experience to assemble this quality document.
BS 7671 Inspection & Testing Audits

BS 7671 Inspection & Testing Audits

Installations that conform to the standards laid down in BS7671 are regarded by the HSE as likely to achieve conformity with the relevant parts of the Electricity at Work Regulations 1989.
Chapter 62 in the IET Wiring Regulations covers Periodic Inspection and Testing requirements. Regulation 621-01 states that periodic inspection and testing of an electrical installation shall be carried out to determine, so far as is reasonably practicable, whether the installation is in a satisfactory condition for continued service.
Regulation 622-01 stipulates that the scope of the periodic inspection and testing shall be decided by a competent person, taking into account the availability of records and the use, condition and nature of the installation.
Table 3.3 in the IET Inspection and Testing Guidance Note 3, indicates which periodic tests are to be carried out on existing installations. The person carrying out the testing is required to decide which of the tests are appropriate by using their experience and knowledge of the installation being inspected and tested and by consulting any available records.
It is important that any periodic inspection and testing regime put in place meets the standards of the codes of practice but at the same time is a practical operation which can be completed efficiently and with minimum disruption to the business. The ability of the company to clearly demonstrate compliance is a key requirement of any new periodic inspection/testing package.
Periodic inspection and testing is necessary because all electrical installations deteriorate due to a number of factors such as ageing, excessive electrical loading, corrosion and general wear and tear.
A periodic test and inspection may be less onerous than an initial one. Completing unnecessary periodic testing can be dangerous, disruptive and costly. This is often misunderstood by companies wishing to achieve legal compliance.
Safety Instrumented Systems Capability

Safety Instrumented Systems Capability

Before the introduction of IEC 61508 and IEC 61511 standards, major chemical companies devised and worked to their own engineering guidelines for the design and implementation of trip and alarm systems.
Inglewood Engineering has worked continuously for a number of these companies since its formation in 1983. Our engineers have lived with the standards as they have evolved and are as familiar as any practitioners with what is required to comply. However, it is important that those engineers who are practising in this field are independently assessed and validated so that customers can have true confidence in their abilities. To this end our personnel seek and have attained the coveted accreditation of TÜV Functional Safety Engineer.
At Inglewood, we are involved with initial hazard analysis, determination of risk reduction, production of the safety requirements specification, defining the safety integrity levels, safety instrumented system design, system reliability calculations and site trip testing.
We regularly audit existing plant alarm and trip systems to ensure compliance with the latest standards.
DSEAR Site Audit

DSEAR Site Audit

Inglewood Engineering offer an invaluable DSEAR Site Audit service. The first step to achieving compliance is to assess what gaps there are, if any, between your current level of compliance and the level set by DSEAR. We provide you with an overview of your present status and explain how you can address any areas of weakness.
The audit takes the form of a formal step-by-step review of your installation, policies and procedures against the provisions imposed by DSEAR. An engineer leads the review and their findings are reported to you in terms of practical recommendations that point the way to full compliance.
We undertake this service throughout the UK wherever DSEAR applies, in new builds, at existing sites that are still not compliant, and following plant modifications.
And of course, we agree a fixed price up front before work commences.
It is essential to get your DSEAR response right. Overdoing it can be unnecessarily costly; doing too little can turn out more so. We offer an independent audit that is straightforward and authoritative, and one that promises a constructive route to compliance right from the outset.
Non-Conformance Management

Non-Conformance Management

Non-Conformance Management is another DSEAR service offered by Inglewood Engineering.
Non-Conformances, or snags, are categorised as Critical, Major or Minor during site inspections in order to prioritise the resulting actions. The Corrective Action Schedule report then presents our findings in a form that collates the issues for easy handling.
Typically we would advise the client on the most effective way to deal with the non-conformances. This may best be done by the client’s own workforce. If that is not feasible we will provide the means to expedite the remedial work.
EAWR Electrical Compliance − Experience

EAWR Electrical Compliance − Experience

Inglewood Engineering have worked on electrical compliance issues since we were formed in 1983.
Our design office specialises in electrical building services and cut-and-carve modifications to control and electrical plant. We use the latest design verification software and AutoCAD for drawings, to support our engineers and designers. Our inspectors are fully qualified and have generally progressed from a design background.
We have completed Electricity at Work Regulations (EAWR) audits and BS 7671 inspection and testing services for all types of premises. These include hazardous areas, safe areas, industrial areas, laboratories, office buildings etc. We draw on a proud history of service to many organisations, both national and international, to advise our clients and help make their premises compliant.
EAWR Compliance − Services

EAWR Compliance − Services

Where clients are seeking reassurance regarding their compliance with the Electricity at Work Regulations (EAWR) , we offer an independent audit and summary report on their plant.
Should more be needed we provide a full inspection/testing service. This is backed up by a team of professionals, headed by a Chartered Electrical Engineer, who will advise on any issues. Electrical distribution can easily get out of control and cause supply problems, especially in large networks. Pinpointing improvements in maintenance and design can save both time and money.
We always seek the best way of working with our clients. This invariably means working closely with the local technicians who are familiar with the particularities of the site.
Ultimately we aim to ensure that the client is able to achieve and demonstrate compliance with the relevant parts of the Electricity at Work Regulations, whilst operating a dependable electrical distribution network.
EAWR Audits

EAWR Audits

Inglewood Engineering offer EAWR site audits to help you understand the regulations and advise you on how to ensure compliance.
Our compliance engineers conduct a thorough review of the physical state of the installation, and the relevant documentation records. This covers electrical distribution equipment as required by the EAWR. The audit report then details what needs to be done to achieve compliance.
Inglewood carry out audits on new installations, existing buildings and plant modifications, and agree a fixed fee before work commences.
An independent assessment by a competent body offers additional assurance to your company. It’s a statement of how effective your current practices are. And it gives you time to get your house in order. Unfortunately that’s something you wouldn’t necessarily get after a surprise visit from the HSE.
Single Line Diagram & Record Compliance Documentation Updates

Single Line Diagram & Record Compliance Documentation Updates

In order to comply with Regulation 514-09-01 of BS7671, clients must ensure that a master electrical diagram is available (for any installation other than a simple one). Where an existing single line diagram does not exist or where it’s out of date, our engineers work with our CAD office to provide the necessary validated electronic drawings for your use.
It is vital that items of sub-distribution have unambiguous labelling that corresponds with the master site electrical single line diagram. Our engineers verify which circuit is which by test, and fit new labels as required.
It is also important that final circuits are properly identified. Where this is not the case, we will ascertain the final circuit arrangement and provide new electronic schedules for inclusion with your site documentation.
Depending on the size of the installation you may hold a variety of electrical record drawings, motor schematics, lighting and small power layouts etc. And if these need to be brought up to date we will take care of that back at our office.
Instrument & Control Design

Instrument & Control Design

Inglewood Engineering complete Instrument and Control Design for all types of process industry. Our designers are led by Chartered Engineers who have many years of experience in the industry.
We are familiar with Scada systems, PLC control and relay logic and are used to developing control packages from initial concept to final installation. Modifications to existing plant is a frequent requirement and one with which we are skilled.
Our scopes of work are tailored to the needs of the task. As appropriate we produce User Requirements Specifications and Instrument Specifications, and design the Control Loops, Control Panels, and Plant Layouts etc that are characteristic of a well designed job.
Following on from design it is normal for us to carry out the functional testing of the completed installation and support our client with his commissioning.

Control Panel Design

Control Panel Design

Inglewood Engineering provide control panel design that might be needed for a particular safe or hazardous area instrument application.
We work closely with our client, observing any limitations imposed by the site and establishing the functional and operational needs of the job. Typically this will entail some site investigation and assessment of existing documentation.
We offer a complete service in conjunction with recommended panel manufacturers for those clients who prefer to outsource delivery to a single supplier. This includes factory acceptance tests, functional testing in situ and commissioning support. For panels situated in hazardous areas this would also include detailed inspections required by DSEAR for new installations.
To learn more about our control panel design services and the assessments we carry out fill in our contact form or call 01625 410100 and speak to a member of our team.
Loop Drawings

Loop Drawings

Documentation records must reflect items out on plant to demonstrate compliance and ultimately uphold safety; and accurate loop drawings are an essential part of this.
As part of our inspection work we check that what is installed matches the existing drawings. If there are discrepancies, we bring these to your attention and can revise them as part of the process.
Our interest in terms of DSEAR will primarily be related to the hazardous area. An Intrinsic Safety Diagram may be the most effective way of depicting and recording the safety essentials of a full instrument loop.
DSEAR Management Tool − Complied Electrics

DSEAR Management Tool − Complied Electrics

The physical condition of equipment in a hazardous area is clearly what matters most, more so than any paper or electronic system that describes it. However the best measure of a well maintained plant is a good management system. It proves a commitment to maintenance. And it’s one of the things an HSE inspector will look for. Amongst other things such a system makes it possible to keep track of all the equipment in the area that threatens to be an ignition source.
That’s the safety and regulatory aspect. But it also makes sense economically; to use the information gained during the verification of a new plant, now mandatory under DSEAR, as the platform for an inexpensive compliance regime.
Complied Electrics, exclusively on offer through Inglewood, is designed to answer any regulatory concerns and to keep you in efficient control.
Its features include:-
Web based system − it can be accessed from anywhere in the World using a standard Web browser.
Any registered user may access or update information as required.
No special software required.
Inventory focussed. Register of all equipment ignition sources in the hazardous area.
Unlimited number of items of equipment.
Unlimited number of users.
