Risk of electric shock through poor socket selection

Risk of electric shock through poor socket selection, in this example standard plastic electrical socket outlets have been fitted in an office floor

It seems quite obvious that if an electrical socket is to be fitted into the floor, it would need to be of a type that has been designed to withstand weight or impact, however someone has ignored this criteria, or has not considered the environment.

A standard plastic electrical socket outlet is designed to be mounted into a wall and would not be suitable to floor mount. The sockets in this photo would easily be broken by; the steel chair leg where the leg could become live through direct contact with the live electrical conductors.

This example was identified by a Veriserv engineer whilst carrying out an electrical fixed wiring inspection and test. The engineer would isolate the sockets and complete an “immediate report” to notify Veriserv’s customer.

The sockets should be of the type that are enclosed in a protection enclosure suitable for use on an office floor. This type of socket would normally have a lid to stop ingress of liquids should they get spilt.

Electrical equipment that is intended for use in the workplace must satisfy the safety requirements of  the  Electrical Equipment (Safety) Regulations 1994  and  must  provide  a  safe connection to the mains electrical supply.

The Institute of Engineering and Technology (IET) publish BS7671, IET wiring regulations seventeenth edition. Section 522.6.2 states that wiring systems shall be selected and erected so as to minimise damage arising from mechanical stress or impact during use or maintenance.

Veriserv would be happy to advise on any electrical compliance matter, or provide you with a quotation to carry out an Electrical Fixed wiring inspection and test of your premises.

Has your Fire Alarm Battery been tested

Has your fire alarm battery been tested recently ? All fire alarms systems have some sort of backup power to maintain alarm functionality if for any reason the mains power fails. For most systems this reserve power would be provided by a backup battery.

For all fire alarm systems it is imperative that the backup battery is tested during routine maintenance.

The battery shown below was removed from a customers fire alarm system by a Veriserv engineer during periodic maintenance of the system.

There are various faults that can effect batteries however this fault is clearly visible in the form of swelling and distortion. This battery has become swollen as a result of overcharging which has been caused by a faulty voltage regulator within the fire alarm panel and excessive current has flowed into the battery after the battery has reached full charge. The constant current will cause decomposition of the electrolyte within the battery and lead to premature aging. At high rates of overcharge a battery will progressively heat up and as it gets hotter it will accept more current, heating up even further. This is called thermal runaway and it can destroy a battery in as little as a few hours.

A Veriserv engineer replaced this battery and repaired the faulty panel to prevent the new battery suffering the same fate.

Operators and owners of non domestic premises have a duty under the Health & Safety at work Act 1974 to provide a safe place of work. In practice this means that all non domestic premises should have a working fire alarm system which is being properly maintained. Veriserv can provide design and installation services together with a suitable on going maintenance regime.

British Standard BS5839 sets out the code of practice for design, installation, commissioning and maintenance of systems in non domestic premises. Section 25.4 states that the following recommendations are applicable: a) The standby supply should comprise of a secondary (rechargeable) battery with an automatic charger, b) The battery should be of the type having a life of at least four years under the conditions of use likely to be experienced in the fire detection and fire alarm system.

A Veriserv engineer would check the age of the battery and carefully calculate the specification of a replacement where necessary.

Veriserv are accredited to NSI Gold standard and can provide guidance if you are un sure of your duties or need some reassurance as to the condition of your fire alarm system. We can also carry out a mandatory Fire Risk Assessment for your premises to make sure any potential fire hazards are identified and addresses.

Portable Appliance Testing why do it

Portable Appliance Testing why do it , In the work place all portable electrical equipment should be subject to ‘User Checks’ carried out by a competent person. As an employer its very important to protect people in premises that you control from electric shock, fire and other hazards. Its also very important to protect yourself and your company from prosecution should an accident occur which is not your fault.

The examples shown in this blog were all identified by Veriserv engineers and demonstrate how your employees could negatively effect safety in your workplace. In other words, employees who ignore the basic principles of electrical safety could land you and others in trouble.

The first example of portable appliance testing why do it, shows a standard 13amp plug where the fuse has been replaced with a peace of metal bar. A correctly rated fuse will blow if the portable appliance develops a fault. This in turn protects the user from potential electric shock and would prevent the possibility of the appliance overheating and causing a fire.

Someone has deliberately replaced the fuse with the bar which is totally irresponsible, given that the appliance is no longer protected at the rated 13 amps. Given the size of the cables it may be that the appliance itself should be connected by a different means to a 13 amp plug. A competent portable appliance test engineer will check ratings and advise accordingly and a veriserv engineer would also disconnect the appliance and issue an immediate report to advise our customer.

This second example was found plugged in and switched on with live conductors showing.

 

Again this is an example where it would be clear to a responsible person that this extension lead is not fit for use.

The third example is another broken extension lead being used in service which clearly exposes people to an electric shock hazard.

Both faults were found by Veriserv engineers during annual portable appliance testing (PAT) and these examples reinforce the importance of maintaining a proper testing regime to protect people in your premises.

Ideally, equipment which has an obvious visual fault should be switched off and taken out of service by an employee or person acting responsibly in the workplace. Only very basic health & Safety training is required to achieve this.

In any event, in the workplace it should not be acceptable for a defect to go unnoticed, therefore the Institute of Engineering and Technology (IET) recommend that formal visual inspections are undertaken periodically by a competent person to identify these hazardous items.

All Veriserv PAT engineers are qualified to the City & Guilds 2377 Level 3 award in the in service inspection and testing of electrical equipment (PAT)

Snake perishes in electrical consumer unit incident

Snake perishes in electrical consumer unit incident – This “incident” may be creative license however the dead snake was found by a Veriserv engineer whilst carrying out a routine electrical fixed wire inspection and test at a domestic property. Although this is a rare situation we would like to highlight the more serious issue of how a domestic consumer unit can be susceptible to fire, particularly if not electrically inspected and tested periodically.

It wasn’t clear from the remains of the snake whether or not it had died directly from an electric shock or from starvation whilst in the electrical consumer unit , but it was clear that it had been in there for quite some time. When it was shown to the tenant living at the property he said that his pet snake had mysteriously disappeared two years earlier and had never been found, so this did explain where the snake had come from.

We would like to raise the more serious issue about consumer units generally and how fires can be prevented by periodic electrical inspection and testing. Consumer units can be the source of a fire caused by overheating of loose terminals, faulty or incorrectly rated breakers, and debris inside the enclosure can be a source of fuel for a fire to start, such as loose paper or other flammable materials.

Here is an example of overheating in a distribution board, again found by a veriserv engineer whilst carrying out a periodic mains fixed wire test.

Most domestic consumer units are made of plastic and a recent update to the 17th edition wiring regulations calls for all consumer units to be constructed using a non combustible enclosure.

The third amendment to BS 7671:2011 (IET Wiring Regulations Seventeenth Edition), includes a new regulation requiring consumer units and similar switch gear assemblies in domestic premises to have a non-combustible enclosure. More information can be found by visiting the Institute of Engineering & Technology (IET).

More useful information can be found by visiting the NICIEC website.

Chapter 42 of the regulations states;

Due to the number of consumer unit fires reported within domestic premises, Regulation 421.1.201 (UK only) has been added and requires  consumer units and similar switchgear to have their enclosure manufactured from non-combustible material or be enclosed in a cabinet or enclosure constructed of non-combustible material and complying with Regulation 132.12. This regulation was implemented on 1st January 2016 to allow manufacturers time to ensure an adequate supply of suitable cabinets or enclosures would be available.

Portable Appliance Testing, Overheated Plug Socket

One good reason to have your portable appliance testing (PAT) carried out. Our fault of the week is a good example of a multi socket electrical extension lead that has become overheated with early signs of burning.

This fault was found by a Veriserv engineer during an annual portable appliance test (PAT) . The socket has become overheated. This could be caused by a loose connection or as a result of supplying an appliance which uses power in excess of the extension leads recommended maximum limit. Most extension leads of this type are rated at 13 amps so this means you should not plug more than one 13amp appliance into the extension socket at the same time. Multiple appliances should be rated at 5 amps.

The plug which connected to the overheated socket is shown below.

It is important that all appliances are fitted with a fuse which is correctly rated for the appliance it powers. A new portable appliance will already be fitted with a sealed plug and correctly rated fuse. The plug shown in this photo is the type that has probably been fitted at a later date. It is important that the fuse rating is checked during the portable appliance test. Veriserv engineers would check this during the test and replace if necessary.

As a result of the PAT test by Veriserv the overheated extension lead and plug would be taken out of service and reported immediately to our customer.

In the work place all portable electrical equipment should be subject to  ‘User Checks’ however in this case it seems the deterioration of this piece of equipment has gone unnoticed. Ideally in this situation, as soon as any damaged is noticed the piece of equipment should be switched off and taken out of service.

In any event, in the workplace it should not be acceptable for a defect to go unnoticed, therefore the Institute of Engineering and Technology (IET) recommend that formal visual inspections are undertaken periodically by a competent person to identify these hazardous items.

Overheated RCBO terminals could cause a fire

Our “fault of the week” blog posts are all real electrical fault situations that have been reported by Veriserv engineers whilst carrying out Inspection & Testing of electrical installations at client sites. This fault is an RCBO (residual current breaker with overcurrent) that has become overheated and burnt.

This C1 electrical defect is a result of a loose connection causing arcing at the RCBO terminal. Not only would this lead to a failure in the RCBO and electrical circuit, there would also be a serious threat of fire should the melted plastic ignite in some way.

The Veriserv engineer would immediately isolate this circuit and report the defect to the client on what we call an “immediate report”. This so the client is aware of any defects prior to the engineer leaving site. The RCBO and adjoining cable would be replaced if the client requested that Veriserv carry out the remedial repair.

Overheated RCBO terminals could cause a fire, this fault would be classed as a C1 Fail Code -Danger Present. Risk of injury. Immediate remedial action required.

The Electricity at Work Regulations 1989-Reg 4(2) state “The need for maintenance to be done to ensure safety”.  As such all commercial premises must be electrically tested and certified to ensure they can continue to be used safety.

BS7671 wiring regulations to the latest edition sets out the requirements for all electrical installations in the UK. The Institute of Engineers and Technology (IET) produce guidance notes to enlarge on the wiring regulations and set out guidance on how compliance can be achieved. Guidance Note 3 covers the Inspection & testing of Electrical Installations.

An electrical installation should be periodically inspected by a qualified electrical engineer. Veriserv are experts in this field and will advise any customer who may be unsure of the periodicity or scope of the Inspection & Test. Veriserv will issue an electrical certificate and report to their customer with a statement as to the condition of the electrical installation. Click here for more details.

 

Light fitting with exposed live electrical parts!

Our “fault of the week” posts are published to show the sort of dangerous electrical faults that our Veriserv engineers are finding every day of the week whilst carrying out routine electrical inspection & testing at our customer’s premises. This light fitting had exposed live electrical parts.
We hope that in posting examples like this, we will raise more awareness and hopefully this will lead to fewer electric shocks and electrical fires.

During a routine electrical inspection & test a Veriserv engineer found this light fitting with exposed live electrical parts.

At an initial glance a casual observer may think that the connecting terminals visible on this fluorescent light fitting are possibly for future use and are otherwise dormant. However, when investigated by the Veriserv engineer, a voltage measurement identified 230 Volts between the Line (Live) terminal and earth. The fittings were placed at around 8 feet high so in normal use it is unlikely that any person would come in to contact with them.

During maintenance however, such as changing a tube, the possibility of direct contact is very likely causing the inevitable electric shock that could be even more serious due to a likely fall from height!

To rectify the defect fully an “end cap” is required that will cover the terminals. The cap is not immediately available from a wholesaler therefore the Veiserv engineer made the fitting safe to enable the remaining lighting to be used and not affect the occupancy of the building.

Useful Health & Safety information and advise can be found by visiting the Heath & Safety Executive website.

Remember Electric Shocks can kill or injure by;

preventing the heart beating properly
preventing the person breathing properly
cause severe muscle spasms
cause electrical burns
start an electrical fire

Electrical Standards and Approved Codes of Practice can be found on the Health & Safety Executive website.  

It’s a legal requirement for any property owner to provide a safe place of work for employees or for persons within a public accessible area. To satisfy this requirement suitable and proper inspection and maintenance must be carried out at regular intervals. Veriserv are specialists in the areas of Electrical Inspection & Testing and Fire Alarm Testing & Maintenance. We can take the worry from you by providing a no obligation survey and advising you on the most appropriate course of action. Feel free to contact us by phone or on line form.

Fuse replaced with steel rod – Portable Appliance Testing

This fault of the week underlines the importance of carrying out Portable Appliance Testing.

When a fuse blows you often find yourself hunting around for a suitable replacement. Unfortunately, in this instance, a fuse was not available so an enterprising individual prepared one from a steal rod. It may have even been turned down on a lathe such is the perfect fit!

For the purpose of protecting the appliance and the user in the event of an electrical fault, this item is obviously unsuitable, meaning not only your electrical appliance breaking, but there is a huge potential of a fire risk. Is it really worth it?

All users of portable electrical equipment in the work place should undertake ‘User Checks’. However for non-trained personnel it is recommended that the plug top is not removed.

Unfortunately, this limited inspection may lead to a significant defect of this nature going unnoticed. Therefore the IET recommend that formal visual inspections are undertaken periodically by a competent person to identify these hazardous items.

A Veriserv engineer would replace the fuse during the Portable Appliance Testing and advise the client of his findings. Keeping both the client, and all those around the electrical item, safe and sound.

Our mission is to provide every single customer with an outstanding service that is fit for purpose and delivered by experts to reduce risk. As you can see from our other faults of the week, regular visits from a professional can cut down the risk of electrical faults, fire and disrupted security, to you and your workplace.

So if you know you are due a service, or have some concerns about your premises, please call 01543 225306, or fill out one of our contact forms to arrange a free assessment of your premises, with one of our fully trained engineers.

Damaged Conduit exposing live electrical connections

In this weeks fault of the week, we are looking at a damaged conduit exposing live electrical connections.

In this electrical fault, we have a plastic conduit, which is exposing live electrical connections that has been damaged and pulled away from its fixing,  which has exposed connections.

This was found in a public area and the loose cables could easily be accessed, pulled and detached, which would allow live terminal or cable ends to be freely exposed.

During an Electrical Tests and Inspection, this would be categorized as a fault requiring immediate attention. We would notify our client with an immediate report, then carry out an immediate repair, or make safe. Check out our Electrical Inspection and Testing Service.

Our mission is to provide every single customer with an outstanding service that is fit for purpose and delivered by experts to reduce risk.
