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.

Take a look at the new models in our site alarm product range.

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.

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.

Retrofitting or Replacing Fire Door Seals

Tuesday 20th March 2012

Following a fire risk assessment, doors are sometimes re-designated as fire doors if the door and frame are substantial enough to be justifiably counted as a nominal fire door. The same applies to older fire doors which do not follow the latest specifications. In these cases, fire door seals are retrofitted, and to avoid having to cut a rebate in either the door or the frame, surface mounted fire door seals can be fitted. These are stuck to the frame or door with their self-adhesive backing and sometimes nailed as well to give them increased longevity.

Where a fire door rebate already exists, or the existing rebated fire door seal has been damaged, rebated intumescent fire door seals can be fitted.

We offer a range of fire door seals: fire only, or combined fire and smoke. Both variants contain intumescent material that swells if a fire breaks out to seal the gap around the fire door. Seals that cover smoke also contain a brush-type smoke seal to stop smoke travelling through the gap before the intumescent material expands. There are some applications where a gap should not have smoke seals: e.g. if the fire door has been installed on the exit of a room which has no smoke detectors on its own. In this case, the fire alarm system can only be triggered if smoke can leak out around the fire door and set off the fire alarm system in the circulation spaces, but these cases are quite rare.

Fire door seals are fitted on three sides of a fire door with the gap underneath the door not being covered, though there are products available to prevent smoke from escaping under doors if necessary.

If new fire door seals are fitted for the first time, make sure that fire door hinges, fire door closers and, where necessary, intumescent door lock protection are fitted as well.

Free Water Mist Extinguishers for Qwackers Pre-School

Friday 2nd March 2012

Qwackers Pre-School in Alford, Lincolnshire has been part of the life of generations of local people. It started off in a hall at the side of a babbling brook where ducks swam. The group then moved to a second-hand prefab building that was erected on the site of the John Spendluffe School.

This building has served a good purpose but with many years of wear and tear it became apparent that it was no longer viable to repair the structure any longer. After several years of campaigning Qwackers have now moved into a brand new building on their old site.

We always like to support local causes and as Qwackers is a registered charity we wanted to show our support by installing new extinguishers for them and maintaining the extinguishers on a yearly basis in the future completely free of charge.

We chose to install Water Mist extinguishers, which when deployed will leave no residue and will not cause water damage as with conventional water extinguishers. The Water Mist extinguishers are fitted with a supersonic nozzle, creating a microscopic mist curtain. The water mist removes oxygen from the fire and also cools the material that is alight, reducing the chance of re-ignition. Because the extinguisher is creating a fog rather than a jet, the water mist extinguishers are ideal for schools and nurseries, as children cannot hurt themselves, should they ever set off an extinguisher.

Water Mist extinguishers are also perfect for home, offices, shops and kitchens, and their testing credentials mean they can even be used on electrical equipment too!

What to do with old smoke alarms?

Monday 19th December 2011

Customers ask us occasionally about the recycling of smoke alarms. Here is some information relating to this.

Smoke and heat alarms fall under the WEEE (Waste Electrical and Electronic Equipment) regulations. The biggest burden, with regards to the recycling of these goods, falls on businesses manufacturing, rebranding or importing alarms or any other electrical equipment. Retailers like us have to follow a reduced set of regulations.

Retailers have to pay a fee to be allowed to recommend their domestic customers to drop their old smoke and heat alarms off at local recycling centers (Distributor Take-Back Scheme) rather than returning them to Safelincs for passing on to the manufacturers. As the directive states that the customer should in this case dispose of the old alarm themselves at the recycling centers we could in theory refuse to accept old smoke alarms back from domestic customers. However, we allow customers to send us their old units as a courtesy when they purchase from us.

Ideally, as stated above, domestic customers should drop their old alarms off at their local recycling centers, however, they can also dispose small numbers of alarms in their normal refuse. Quite often customers are concerned that the crossed-out wheelie bin on the back of the alarm means that they must not place the unit in a normal waste bin. This is a mis-understanding, the crossed-out wheelie bin just means that this product falls under the WEEE regulations and ideally should be recycled. Nevertheless, small numbers of smoke alarms are permitted in the household waste. There is currently no differentiation in this respect between the ionisation and other smoke alarms despite the ionisation alarms containing small amounts of radio-activity.

There are WEEE rules that differ for domestic customers and businesses. Business smoke alarm users can drop small numbers of old alarms off at the recycling centre, where the cost for recycling will be passed on to the manufacturers. Business customers can also pass the smoke alarms on to us. We then pass them on to the manufacturers. This is only the case if they buy new smoke alarms from us at the same time or if they bought the units from us in the first place (there are some detailed rules relating to this regulation, which have been left out for simplicity).

P50 self-maintenance extinguishers installed in our local primary school

Tuesday 1st November 2011

Alford Primary School, local to our Safelincs headquarters based in Lincolnshire has installed our Britannia P50 self-maintenance fire extinguishers. These extinguishers carry a 10 year guarantee and do not need a service engineer to carry out the yearly inspection.

Having a 10 year guarantee and not requiring a refill after 5 years or any engineer servicing visits for the life span of the extinguishers is a huge cost saving for schools. As budgets are always under scrutiny and with the government looking for additional cuts, the savings achieved by changing to P50 make great sense.

When we installed the P50 extinguishers in the Alford Primary School, training was given to school representatives to be able to carry out the simple yearly inspection themselves. P50 extinguishers are accepted by most insurance companies.

There is a video available to demonstrate how easy the extinguishers are to self-maintain. The extinguishers, which have an inner core of Kevlar (the same material used in bullet proof vests), are corrosion-free and are suitable for all outdoor applications as well as indoors.

Intumescent Pipe Collars – A Guide

Monday 17th October 2011

We recently introduced a new range of Astroflame pipe collars. As we receive many questions about the use of pipe collars we felt that a write-up about these collars might be helpful.

What are pipe collars?

Where plastic soil and water pipes pass through fire compartment walls and floors, fire could spread between these building compartments as the pipes melt. Pipe collars are used in these situations to stop the spread of fire. They are fitted around the pipe and on exposure to heat from a fire they rapidly expand inwards to squeeze the collapsing plastic pipe until the aperture is completely sealed. Astroflame pipe collars can be used on UPVC, ABS, MDPE, HDPE and PP pipes up to 225mm diameter. They are rated at 4 hours fire resistance and are tested to BS476: Part 20: 1987 and EN1366-3. They also come with NHBC Type Approval.

What are pipe collars made of?

Intumescent pipe collars are made from intumescent material (based on heat reactive graphite ) bonded to the inside of a steel sleeve. The steel sleeve is powder coated and can be opened and fitted around the pipe. They are closed with a toggle clasp.

How are pipe collars fitted?

Our collars are designed for surface mounting, with the option to fully or semi-cast into masonry floors or walls. The fixing brackets provided can be used for securing the sleeve with non-combustible screws or bolts, or to assist ‘keying-in’ if collars are for recessed installations.

For horizontal installations the collar may be surface mounted or recessed and should be located on one or both sides according to the direction of risk.

Fitting to Masonry/Block Walls

1) Attach the Astro Collar to the pipe so that the integral mounting lugs are pressed tight to the surface of the wall.

2) Mark the position of the bolt slots in the mounting lugs onto the surface of the wall with a marker pen.

3) Rotate the collar slightly (or if access is restricted remove from pipe) and drill holes at the pre-marked positions to suit the anchor bolts being used.

4) If the surface of the wall is very uneven, it is recommended to bed the collar onto a bead of Astroflame Intumescent Mastic to improve the smoke seal efficiency.

5) Insert the anchor bolts and tap home. Relocate the collar in position ensuring that the toggle clasp is snapped closed and that the bolt heads are protruding through the slots in the mounting lugs. Tighten the nuts onto the bolts.

6) NOTE Where there is a fire risk on both sides of the wall, or the direction of fire risk has not been determined, then an Astro Collar should be fitted to both sides of the wall.

7) The collar can also be semi or fully cast into the masonry wall using Astro FM Compound fire resistant mortar.

Fitting under concrete floor slabs

1) Attach the Astro collar to the pipe so that the integral mounting lugs are pressed tight to the soffit (underside) of the concrete floor.

2) Mark the position of the bolt slots in the mounting lugs onto the concrete surface with a marker pen.

3) Drill the bolt holes at the pre-marked positions to suit the anchor bolts being used, (the minimum recommended size of non-combustible anchor bolt is 6mm dia. x 25mm long).

4) If the soffit (underside) of the concrete is very uneven, it is recommended to bed the collar onto a bead of Astroflame Intumescent Mastic to improve the smoke seal efficiency.

6) The collar can also be semi or fully cast into the soffit using Astro FM Compound fire resistant mortar.

Fitting to metal stud partition walls

Fit to both sides of the wall!

1) Attach the Astro Collar to the pipe so that the integral mounting lugs are pressed tight to the surface of the partition wall.

2) Mark the position of the bolt slots in the mounting lugs onto the surface of the wall with a marker pen.

3) Rotate the collar slightly (or if access is restricted remove from pipe) and drill holes at the pre-marked positions to suit the fixings used.

4) If the surface of the wall is very uneven, it is recommended to bed the collar onto a bead of Astroflame Intumescent Mastic to improve the smoke seal efficiency.

5) Insert the non-combustible fixings. Relocate the collar in position ensuring that the toggle clasp is snapped closed and that the bolt heads are protruding through the slots in the mounting lugs. Tighten the nuts onto the fixings.

Camping deaths due to carbon monoxide poisoning

Thursday 18th August 2011

During July and August this year there have been several deaths reported due to carbon monoxide poisoning in tents. One particular tragic death was that of a 35 year old woman, who was found dead next to her children aged seven and four and her husband. The children and husband were taken to hospital where they were later released, but it was said that they only just escaped with their lives. It is believed that the CO poisoning was due to carbon monoxide fumes entering the tent as a result of the barbecue being moved to the tent entrance to provide some warmth for the family.

These devastating incidents could be avoided if the dangers of carbon monoxide were more widely known.

This summer the temperatures have not been very high and many campers are finding themselves unusually cold at night in their tents. As there are no extra blankets available, many campers have started to bring camping BBQs or gas stoves into the tent to warm it up before going to sleep. Campers have also started to bring their BBQs into their tents to continue cooking due to it starting to rain.

Bringing gas or coal fired cooking appliances inside tents and caravans fills the space quickly with carbon monoxide gas, a byproduct when burning a fossil fuel. The gas then renders the occupants unconscious and death can occur as a result.

Under no circumstances should gas or charcoal appliances be brought in or close to a tent. The carbon monoxide gas can linger inside the tent long after the appliance has been moved away. As the gas is odorless and colourless there is no way to detect if the gas is present. The gas makes the occupant drowsy and once in this state unable to respond to other warning signs such as headaches and nausea.
