At RES Fire Protection Engineers, we offer powder and CO2 extinguishers for electrical-based fires. A powder extinguisher can be used on electrical hazards when combustibility is a danger (including applications on engines and machinery). A CO2 extinguisher is ideal for instances where vast amounts of electrical equipment is on fire, i.e. in an office or server room full of computer components.

Powder extinguisher

Powder extinguishers are very versatile and can be used on class A, B and C fires. They can be used on fires involving electrical equipment, but there is a risk that the fire could reignite, as the extinguisher cannot cool the fire down. Powder extinguishers are only suitable for open spaces and should be used in areas where there is plenty of ventilation, as they can create breathing difficulties and loss of visibility (especially in smoke-shrouded locations). They shouldn’t be used indoors unless there is no other option. Powder fire extinguishers are marked with a blue label.    

CO2 carbon dioxide extinguishers

If you need a fire extinguisher for a large space containing great volumes of electrical equipment (such as a server room with lots of computers, or a production line with lots of electrical machinery), the safest choice is a CO2 carbon dioxide extinguisher. This type of extinguisher can be used without leaving a residue (unlike powder and foam extinguishers). A CO2 extinguisher smothers a fire so that it doesn’t receive extra oxygen that can fuel it and cause it to spread. It reduces the supply of air to the fire, and is ideal for application to electrical equipment that is ablaze. CO2 extinguishers are marked with a black label.

RES Fire Protection Engineers offer both powder and CO2 fire extinguisher solutions for environments containing electrical equipment, including the following:

What should you use a water fire extinguisher for?

A water fire extinguisher should be used on textile fires, as well as fires caused by burning paper or wood materials. They are also suitable for any other ‘Class A’ graded fires. A water fire extinguisher is ideal for cooling down fires while extinguishing them. In the case of fires caused by burning textiles, the liquid water saturates the fabric to extinguish the flames. Because they do not contain any harsh chemicals, water fire extinguishers are ideal for children’s play areas, food-preparation areas and in areas where there may be vulnerable people. They are also environmentally friendly. Many businesses choose water fire extinguishers because they are easy to refill and cost-effective. That said, a large quantity of water fire extinguishers is needed to cover larger areas, as the water is very quickly used up within a single water fire extinguisher. Sizes available include capacities of 3 litres, 6 litres and 9 litres.

If you intend to use a water fire extinguisher to fight fires caused by electrical equipment, extinguishers with special chemicals inside them are available to prevent current flow and to ensure safe application without electrocution. Water fire extinguishers work well with CO2 extinguishers, and are suitable for home use.   

What does a water fire extinguisher look like?

Water fire extinguishers are red in colour and match the body of the extinguisher. They usually have ‘water extinguisher’ marked on them. At RES Fire Protection Engineers, we always recommend installing signs next to your fire extinguishers to clearly indicate their purpose and nature.

Limitations of water fire extinguishers

Never use water fire extinguishers for the following types of fire:

• Electrical fires (unless they have special chemicals inside to prevent electrocution)
• Cooking related fires (such as a chip-pan fire).
• Fires involving gasses such as methane
• Fires involving highly flammable substances such as petrol or alcohol

How to use a water fire extinguisher

Water fire extinguishers are very simple and safe to use. Remove the safety pin to break the seal on the extinguisher, before pointing the nozzle at the base of the fire and spraying by squeezing the handle. Ensure that the fire is properly extinguished (keep spraying if you are unsure).

Water fire extinguisher purchase and hire from RES

Having the correct lighting installed in a premise is very important to the health and safety of those using it particularly if it is a workplace. Correct LED emergency light installation makes it quicker and easier to identify hazards while making an environment easier and more comfortable for people to work in because of optimum light levels. Poor lighting can have a detrimental effect on employees’ and visitors’ health in an organisation’s premises, including:

• Eyestrain
• Migraine and headaches
• Sick Building Syndrome
• Epileptic fits/seizures

Having the correct LED emergency lighting is essential for any business and or premises owner, especially in cases where a sudden loss of light would prevent safe escape from a building in an emergency. At RES Fire Protection Engineers, we offer the following services for LED Emergency light solutions:

• Installations
• Regular inspection and testing
• Repairs
• Fault identification

LED Emergency lighting and the law

LED emergency light solutions are a UK legal requirement in all non-domestic and certain types of residential premises, as they ensure that a building is compliant with relevant British Standards and the law (Regulatory Reform Fire Safety Order 2006). This is something we can check for you at RES. We can also advise on and provide emergency LED lighting for your business, so that you can have a bespoke solution based on your business requirements. Regulations regarding LED emergency lighting are very specific, and you need to adhere to the following areas in order for premises to be compliant:

• Illuminate escape routes adequately for ease of visibility
• To provide sufficient illumination so that all users of a building can effectively access escape routes
• To use lighting in an effective way so that all fire alarm call points, fire extinguishers and other safety equipment can be easily located
• To provide sufficient lighting so that proper shut down procedures can be carried out in high risk locations 

LED emergency lighting needs to be activated for the entire period that a danger exists, or until normal lighting is restored for work to be undertaken as normal. If a normal lighting system fails in the event of a fire, a back-up power source is required for LED emergency lighting to fully function as necessary. This can be achieved by way of battery packs to each LED emergency light or by way of a centralised battery system To prevent glare, it is important to LED emergency lights should be mounted at least 2m from the floor so that effective light can illuminate all areas around a building and various escape routes.

Types of emergency lighting system

Maintained – LED emergency lights that operate as a normal light fitting and can be controlled with all the other lights in the area, however when the power fails the maintained emergency fitting will continue to operate but at a lower light level.

Non Maintained – Is normally switched off, with its batteries being continuously charged and a green LED showing fully charged. When the power fails then the fitting switches on using its battery supply. Non-maintained fittings are not part of the general lighting but are fittings such as emergency exit signs

Fire safety signs

Fire safety signs are essential for keeping those in a non-domestic building safe, ensuring that staff and visitors know what to do and where to go in the case of a fire. At RES Fire Protection Engineers, we have a range of signs that suit current fire safety regulations and offer installation as well as guidance, advice and training.  

By having good quality fire safety signs that are in accordance with fire safety regulations, you can help reduce this figure and keep your staff and visitors safe. Our fire safety sign range includes fire exit signs, fire action signs, mandatory signs, emergency plan and procedure signs, warning signs, fire equipment signs, fire assembly point signs and fire extinguisher signs.  

Types of fire safety signs

Mandatory signs

These fire safety signs are blue and circular in shape with a white pictogram that must be obeyed in accordance with UK fire safety law. Mandatory fire safety signs advise all people within a building on actions that must be followed to prevent fire or accidents, such as wearing a hard hat in a workshop. These signs should be displayed near entry points to a building, and on fire doors that must be kept shut, kept locked shut or automatic doors that are held open and must be kept clear.

Fire action notices indicate actions that building occupants must do in the event of a fire. These signs take the form of white text on a blue background, although they are not always in a circular format. The blue and white colours used on the signs emphasise their mandatory nature. A general-purpose mandatory sign is a white exclamation mark on a blue circle, which is most commonly positioned next to a fire action notice.

Safe condition signs  

This type of fire safety sign takes a green rectangular form with a white pictogram and text located centrally. It indicates the nearest fire and emergency exits and escape routes, as well as first aid kits and other necessary safety equipment. These signs must always comply with Health and Safety (Safety Signs and Signals) Regulations 1996, current British Standards for fire safety signage and the 1974 Health and Safety at Work Act.  

Fire fighting signs

Red fire fighting signs indicate where safety equipment is located to tackle a fire, such as fire extinguishers. Fire fighting signs can also signal fire alarm activation points. They are often red and rectangular in shape with white writing and a pictogram.   

Warning signs

These fire safety signs are triangular in shape, yellow in colour, and act as a warning to building occupants that there are dangers nearby that are a great risk in the event of a fire – such as the placement of a combustible liquid or radioactive material. These signs are required by the Health and Safety (Safety Signs and Signals) Regulations 1996 and in specific cases by the Dangerous Substances (Notification and Marking of Sites) Regulations 1990.

Prohibition signs

Prohibition signs are circular red signs with crossbars running through them, indicating that certain actions are prohibited due to their dangerous nature. For instance, in the case of a fire risk, a sign may indicate that smoking is prohibited in certain areas. All companies should make employees aware of prohibition signs and how they relate to their duties within an organisation.

Supplementary signs

Directional arrow signs in green, red and yellow colours are supplementary signs that point out safety exits or fire safety equipment.

Arson Attack Closes School

Just as the new school year is about to commence, the all too familiar scene of arson attacks on schools looks set to keep some establishments either closed or in crisis.

On Sunday 25^th August 2019, a School in Dunfermerline for 1400 children was significantly damaged by fire and is facing a very challenging new term.

Passive fire safety measures can help minimise and slow the spread of fire. RES can provide Fire Stopping services such as installation, maintenance and repairs for your school or educational premises.

See our case study on Fire Stopping for Berkshire Schools for an example of our work.

Aqueous Film Forming Foam (AFFF) fire extinguishers are appropriate when used to fight fire caused by burning substances such as wood. They are also suitable for fires involving the igniting of flammable liquids such as petrol. This is because of the nature of the foam extinguisher, as the foam inside can expand and engulf burning liquids and objects. The foam can also soak into materials that are on fire, such as fabrics. Inside a foam fire extinguisher there is a certain amount of water, which cools the fire down while the foam starves the fire of oxygen, helping to minimise its spreading action.

The main body of an AFFF foam fire extinguisher is typically red. The identification field will be cream coloured for ease of recognition.

Foam fire extinguishers are great for use in the office and home. Care should be taken when cleaning up foam discharge from the extinguisher, or the actual extinguisher’s disposal, as the foam inside is carcinogenic and has the ability to poison. Always recycle a fire extinguisher responsibly. At RES, our fire extinguisher servicing engineers can recycle your extinguisher for you so that it is disposed of in a responsible manner.

RES Fire Protection Engineers offer foam fire extinguisher services, including the following:

Fire extinguisher sales and hire

Choosing a fire alarm system

Fire alarm systems are essential to all businesses and corporate/commercial use buildings in case of a fire. Fire alarm systems save lives by alerting occupants within a building of the present danger so that they can evacuate a building quickly and safely in the event of a fire.
The type of fire alarm system installed in a building depends on the structure of the building, the purpose of the building and how these two criteria relate to current fire safety legislation. All non-domestic premises including common parts of houses in multiple occupations (HMOs), those premises used by the self-employed (including family-run businesses) and the voluntary sector must comply with The Regulatory Reform (Fire Safety) Order 2005.

Mains Powered Systems

BS 5839-6:2019 Fire detection and fire alarm systems for buildings. Code of practice for the design, installation, commissioning and maintenance of fire detection and fire alarm systems in domestic premises.

Types of fire alarm system
Fire alarm systems all generally work in the same way. If a fire or smoke detector detects fire or smoke, or if someone breaks the glass on an alarm system wall unit (known as a manual call point), an alarm will sound to warn people in the building that they need to evacuate due to the risk of fire. It is also possible to have a fire alarm system that sends a signal to a local fire brigade so they are sent out to the building as soon as the alarm is raised. There are four main kinds of fire alarm system, these are:
⁃ Conventional
⁃ Analogue addressable
⁃ Addressable
⁃ Wireless

Conventional fire alarm systems
With a conventional fire alarm system, there are a number of detectors that form a network that is wired to a main control panel in zones. A ‘zone’ is a circuit, and normally there is one ‘zone’ or ‘circuit’ per floor in a building. A conventional alarm system enables you to determine which zone the alarm was first raised in. This makes it easier to determine where the fire originally started and is essential information for firefighters. There is typically an end of line device on all circuits for monitoring. There must always be a zone plan clearly displayed next to the fire alarm control and indicator panel for reference purposes.

Analogue addressable fire alarm systems

With an analogue addressable fire alarm system, you can receive details about individual detectors so that you have a higher level of detail in comparison to details of a ‘zone’ where the fire started. This type of alarm system is most common in large commercial buildings to give better identification of a fire’s source. As a result, they can be more expensive. The fire control panel receives details from each detector device regarding whether there is smoke, heat or a fire present.

Addressable fire alarm systems
Addressable fire alarm systems are similar to conventional systems, except that the control panel is able to find exactly where the alarm was first raised. The alarm system is wired as a large loop, with multiple devices connected. This enables a person to quickly determine an alarm’s location. The positives of an addressable fire alarm system include better handling of false alarms, better reliability, lower wiring costs, and a large loop that is less likely to lose connection.

Fire alarm system design
If you hire a fire alarm system designer, they will need to determine the following information:
⁃ The type of system that is required
⁃ The parts of the premises that need a fire alarm system
⁃ How occupants will be affected
⁃ How the fire brigade will be contacted (i.e. should the device need to do this for you)
⁃ How many manual call points you will require
⁃ Fire safety procedures currently in place
⁃ Any other ongoing work that is currently taking place in the building (contractors may have to be consulted)

Wireless fire alarm systems
Although a wireless fire alarm system is more expensive, for some types of building (such as a listed building), where wiring for a fire alarm system is not do-able or permitted, a wireless system makes a great solution. With a wireless system there are no cables present between the control panel and detection devices, so there is no need for cable testing. All wireless systems must comply with EN54-25 standards, and must have multi-frequency links to ensure that signal strength is high at all times.
RES is an approved Hyfire wireless alarm installer – a brand that is synonymous with advanced and innovative wireless fire alarm solutions. The Hyfire system integrates both wired and wireless devices with industry-standard control equipment.

Fire alarm systems from RES
RES provides comprehensive fire detection and alarm system design solutions, as well as installation and testing/maintenance services to ensure that your building complies with British Standards BS5839 Pt1.

Depending on our inspection of your premises, we may recommend the following products to you that we can install:
⁃ Manual call units (also known as ‘break glass’ units
⁃ Point detectors (to detect smoke, fire, heat, radiation or carbon monoxide)
⁃ Multi-sensor detectors (to reject false alarms by working with currently installed detectors)
⁃ Optical beam detectors (for larger spaces)
⁃ Line type heat detectors (detectors for averse conditions or large industrial spaces such as car parks)
⁃ Aspirating fire detectors (fire detectors that analyse the air and send this air to a central detection unit through pipes)
⁃ Wireless fire alarm systems
⁃ Visual alarms and beacons (in case there is a risk of audio fire alarms not being heard in the cases of disability or building occupants wearing ear defenders)

Check out this “5 MOST COMMON FIRE DOOR FAULTS” infographic

Internal fire doors are used to maintain the compartmentation of a building that is on fire, thereby reducing the risk of a fire spreading. They also give access to escape routes, whilst limiting the passage of smoke throughout the building. Many insurance policies for businesses and commercial buildings require the installation of internal fire doors as a requirement to protect the building and its contents. Another use for fire doors is that they give firefighters more protection when they are attempting to put out a fire.

The majority of internal building doors are made from timber, which will give a most basic level of protection against the spread of a fire. However, only doors that confirm to Fire Door Standards BS476 and BS8214 will give the best level of protection. Internal fire doors are made from metal and are rigorously tested to ensure they meet guidelines and provide the best protection possible against the spread of fire. Such testing is carried out by a door being subjected to hot gas and fire, and a note of the time taken for the door’s integrity to be compromised. Internal fire doors should also have fire-resistant glazing, hinges and self-closing abilities.

Why use internal fire doors?

Fire doors should be inspected once every six months to ensure that they still have the ability to provide the desired level of protection against fire and smoke. Around 3 million internal fire doors are installed in the UK every year, and they are often a first line of defence in a fire to prevent the chance of it spreading throughout a building. It is vitally important that fire doors are well-maintained and are installed to the correct specifications to ensure that they can always protect the occupants of a building. Unfortunately, maintenance of internal fire doors is often not considered until it is too late. It is also common for occupants within a commercial building to have a lack of knowledge regarding their proper use, leading to instances such as fire doors being left open, or damage being left unrepaired.
Fire doors must be used near stairs or corridors where smoke could potentially pass through and spread.
