Replacement of old Kidde smoke alarms

Monday 11th June 2012

As well as testing your smoke and heat alarms on a regular basis, it is important to make a note of when the units actually need to be replaced. Studies have shown that the functionality of smoke and heat alarms can start to deteriorate when they reach a lifespan of 10 years. Each smoke and heat alarm should have a “replace by date” visible on the outside of the unit and we recommend that you adhere to this guideline.

When replacing a smoke alarm it can be quite difficult to recognise a suitable replacement product. In some cases, you may find that the current alarm model has been discontinued. With battery operated alarms, as there is no wiring in place, it is much easier to replace the unit for another smoke alarm with like-for-like features. Mains powered alarms are hard wired and are most likely interconnected during installation. It is because of this that finding replacement detectors can be difficult.

Working with Kidde Safety Europe, Safelincs are able to provide a list of mains powered discontinued Kidde smoke and heat alarms, along with their suitable product equivalents.

Discontinued Alarm	Replacement Alarm
123/9HI	KEKF10
123i	KEKF10
123/9HILL	KEKF10R
223/9HI	KEKF20
223/9HILL	KEKF20R
1275H	KEKF10
323/9HI	KEKF30
323/9HILL	KEKF30R

The new alarms will interlink with other, still working units of the previously installed smoke alarms. This means that there is no need to replace all of the units within a system if only some of the installed detectors have reached the end of their recommended lifespan. All new mains powered smoke and heat alarms are provided with a mounting bracket and a wiring connector. It is important to note that you need to replace the existing mounting base and re-connect the wiring to fit the new units. With any mains powered alarms, all electrical work should be carried out by a qualified electrician.

Safelincs offer a smoke alarm reminder service which allows customers to be notified when their smoke and heat alarms are due to be replaced, when the batteries need to be changed and reminds customers to test their alarms on a regular basis. The service is completely free and customers can choose if they wish to be reminded by email, SMS text message or by Twitter.

New Evacuator Site Alarms

Monday 14th May 2012

Recently Safelincs added several new site alarms to their range. These included the Evacuator Site Guard call point and push button alarms, the Evacuator Tough Guard and the newly released Evacuator Tough Guard Wireless.

All four of these alarms are designed for use in building and construction sites, temporary marquees, camp sites, markets etc. where installing a permanent fire alarm system would be impractical and unnecessarily costly.

The Evacuator Site Guard is ideal for less harsh environments, such as camp sites and markets, while the Evacuator Tough Guard is perfect for busy building and construction sites where it may encounter water, dirt, dust and debris. The Tough Guard features an IP56 rated weatherproof enclosure that copes with harsh weather conditions and the occasional knocks and bumps it may have to endure.

These battery powered alarms can be used as standalone units or linked using 2 core wire. Running interlink cables all over a busy construction site may not be safe or practical, and this is where the new Tough Guard Wireless comes in. The Tough Guard Wireless has all the strength, durability and weatherproof protection of the standard Tough Guard with the added benefit of completely wireless interconnection to other Tough Guard Wireless units. The amazing 18,000m wireless range, long life battery and extremely loud 118dB sounder make these alarms an essential piece of safety equipment for any situation.

Why are Fire Door Closers Important?

Thursday 3rd May 2012

In order for fire doors to function properly, they should remain closed when the door is not in use. As obvious as this sounds, in a busy office building it can be difficult to ensure that fire doors are being closed. Therefore automatic fire door closers are installed to ensure that, after a door is opened, it naturally returns to a closed position where it can offer the maximum fire safety.

Fire door closers are a legal requirement in most settings

How do fire doors closers work?

Door closers work by using the energy built-up when opening the door, to close it. Fire door closers have different closing strengths depending on the weight of the fire door. The closing strength is otherwise known as the EN power size. Smaller and lighter fire doors do not need as much strength in the fire door closer to shut the door. Many door closer models have an adjustable power size. The configuration of the door closers will also depend on the design of the door (inward/outward closing).

How do I check my door closer is working?

This fire door maintenance checker is a useful guide for checking all parts of your fire door to make sure they are compliant and operational. An unlatched or non-operational door closer will not shut the fire door if a fire breaks out. This could have disastrous consequences.

Which fire door closer do I need?

There are a number of different types of fire door closer available including closers that are even concealed within the doors themselves. Free-swing closers enable the doors to be held safely in an open position or to swing freely on the hinges. This can help to improve accessibility, particularly for anyone with mobility difficulties or in busy areas. In the case of a fire, the fire alarm will trigger these hold-open devices and allow the door closer to close the door.

If you are not sure which fire door closer you need, compare features and prices in this overview of fire door closers. Alternatively, contact our customer support team on 0800 612 6537.

CO2 fire extinguisher horns

Sunday 15th April 2012

Unlike other types of fire extinguishers, CO2 extinguishers feature a discharge horn as opposed to a hose. When a standard CO2 extinguisher horn is installed, it is fitted semi-tight, so that it can be swivelled but still holds itself in the chosen position. This is because during operation, the CO2 extinguishing agent causes a standard CO2 horn to frost over. If the horn is held during this time, it can potentially injure the user through freeze burn. An even better solution to this problem is to buy CO2 extinguishers with frost-free horns. These can safely be touched when fighting the fire, giving the user a lot more control when deploying the extinguisher. All Safelincs 2kg CO2 extinguishers have frost-free horns as standard.

Although the standard swivel horn is a popular choice and an economical solution, it does not have the necessary characteristics to protect the user from freeze burn injuries. The frost free horn is double lined and therefore has the insulation to eliminate these risks should the user accidentally hold on to the fire extinguisher horn during discharge.
5kg CO2 fire extinguishers are much larger in size and the discharge component for this is a hose and horn assembly. This does not have a frost free-horn, however, the horn features an integrated handle for safe use during operation.
Should you wish to upgrade the horns on any 2kg CO2 extinguisher to the frost free double lined horns these can be found in the tools and spares section of the website.

Break the Fire Triangle, Kill the Fire

Thursday 5th April 2012

What is the fire triangle?

The fire triangle is made up of three elements, which are the three components needed for a fire to start and burn: fuel, oxygen and heat. Removing one of these elements will prevent the fire from spreading and causing irreversible damage. Fire protection equipment will help you and your staff break the triangle, reducing potential risks of damage to a building or loss of life.

The three elements of fire explained

Heat

Heat must be present for a fire to ignite. Flammable materials constantly release flammable vapours, where heat is present, these vapours will ignite and start to burn.

Once a fire has started, heat from the fire will dry and remove moisture from surrounding materials (fuel), which results in the fire spreading.

Fuel

A fire needs fuel to burn and feed it. Fuel can be in the form of any combustible material such as paper, wood, textiles, oil, liquids etc. Removing the fuel will prevent a fire from spreading or starting in the first place.

Oxygen

Without oxygen, a fire cannot ignite and continue to burn. Oxygen is all around, making this one of the most significant factors of the fire triangle.

How does fire safety equipment break the fire triangle?

Installing fire safety equipment, such as fire extinguishers and fire blankets, can help stop a small fire from spreading. Fire blankets deprive the flame of oxygen by covering it, killing the fire.

Many fire extinguishers, such as foam and water fire extinguishers, work in the same way; either by covering the flame and its fuel to remove oxygen, or by cooling the fire and any nearby fuel, reducing the risk of the fire spreading. Water Mist fire extinguishers deploy a cooling mist, and are safe to use on live electrical equipment up to 1000V, making them an ideal extinguisher for businesses, education, hospitality and the care sector.

Although fire safety equipment can be a useful tool in stopping a small fire from spreading, a fire should only be tackled if staff are trained to use them, and are confident in what they are doing.

Water Mist fire extinguishers are ideal for businesses, education, hospitality and the care sector.

Fire Safety Training Courses

To prepare your staff to effectively extinguish fires, there are a variety of on-site fire safety training courses available. This includes fire safety awareness and fire warden training, as well as evacuation training to ensure that staff can escape to a place of safety until the fire is under control. These training courses will not only reduce the risk of a fire breaking out on your premises by enabling staff to reduce the risk of fire in their daily duties, but also improve responses and outcomes in the event of a fire.

Preventing a fire from starting in the first place is always the best form of fire safety. Encourage staff to keep an eye out for potential causes of fire, such as faulty electrical equipment or hazardous materials, and use flammable liquid storage cabinets to reduce the risk of these flammable liquids igniting.

All staff must be trained to safely evacuate to a place of safety in the event of a fire.

Employers are required by law to ensure that all employees receive adequate fire safety training. Employers must also provide adequate equipment, such as evacuation chairs and evacuation sheets, to ensure everyone in the building can safely evacuate.

FAQs

Q. What element of the triangle does a fire blanket remove?

A. Fire blankets suffocate the flame, removing oxygen from the fire.

Q. What do foam extinguishers remove from the triangle?

A. Foam extinguishers work in multiple ways to fight fire – the foam spray covers the flame and its fuel to remove oxygen, while also cooling the flame to extinguish it.

Introduction to CO2 fire extinguishers

Friday 30th March 2012

CO2 fire extinguishers contain carbon dioxide gas (CO2) under very high pressure (about 55 bar at room temperature) and can be easily recognised by their flute-shaped discharge horn. CO2 extinguishers are colour coded with a black field on the otherwise red extinguisher.

CO2 fire extinguishers suppress fires by replacing oxygen, without which there can be no fire, with the inert CO2 gas. Although the CO2 is very cold when it comes out of the extinguisher, this does not make it a suitable choice for tackling Class A fires, such as solid combustibles like paper, wood and fabrics. Class A fires require water-based extinguishers that penetrate/saturate the burning materialwork to prevent re-ignition. A still smouldering Class A fire could simply re-ignite once the CO2 gas has dispersed.

CO2 extinguishers are these days mainly used in office environments, where they can be used to extinguish fires in electrical equipment. This is due to carbon dioxide being non-conductive and not leaving any harmful residue that may contaminate sensitive circuitry. Please note, though, that the use of CO2 gas on electronics can still damage the circuits through static or temperature shock.

CO2 extinguishers can also be used by experienced operators on Class B fires which consist of flammable liquids such as petrol, oil and diesel, (not including cooking oil).

The properties of CO2 also make the extinguisher a good protective fire fighting device in places like laboratories, clean rooms, engine compartments, generator rooms, boats and flammable liquid storage spaces.

It is not easy to verify whether a CO2 extinguisher is still filled or has suffered a loss in pressure and content. At a filling pressure of 55 bar and room temperature the CO2 in the extinguisher is neither a liquid nor a gas. What this means in practice is that you cannot hear any ‘sloshing’ when you are shaking a CO2 extinguishers. It just feels as if it were empty! The only way to verify that the extinguisher is still charged is to measure its weight and compare it with its manufactured weight stamped on the cylinder. You need very precise scales for this. Also, the discharge horn of the extinguisher has to be removed for this purpose. This is dangerous and should not be done without prior training, as an accidental discharge without the horn can lead to serious injury. The Horn acts as a pressure reducer; when it is removed the CO2 extinguisher discharges like a rocket should the handle be operated!

When ordering CO2 extinguishers, make sure you buy a model with a frost-free horn, as the horn gets so cold that skin could stick to it.

CO Alarm for Caravans and Motorhomes

Friday 16th March 2012

Prepare for the summer season by installing a CO alarm for caravans. Because caravans are a confined space, the potential for the build-up of deadly carbon monoxide gas is greater. If you have already fitted a CO detector, ensure that you carry out your pre-holiday safety checks. This should include checking or replacing the batteries and testing smoke, heat and CO alarms. It is also advisable to check when your alarms need replacing. Sensors in these types of alarms become less effective over time and will need to be replaced after 10 years.
