What to do if my Carbon Monoxide alarm goes off?

CO detectors, or carbon monoxide alarms, are essential for the detection of a deadly gas, carbon monoxide (CO). This gas cannot be seen, tasted or smelt and is only detected with the use of co detectors. It is produced through the incomplete combustion of fuel, such as gas, wood, coal and oil. If your carbon monoxide alarm is going off, do not assume it is a false alarm.

What to do when your carbon monoxide alarm is going off

You should assume that there is CO present and should follow these steps to ensure your safety.

  • Stay calm, open doors and windows to increase ventilation
  • Where safe to do so, turn off any fuel-burning appliance
  • Leave the premises and notify other occupants of the potential carbon monoxide leak (you should also notify any occupant of premises adjoined to your home as CO can seep through walls and floors
  • Call Gas Emergency Services 0800 111 999 or a local Gas Safe Registered Engineer to check for the source of carbon monoxide
  • Get medical help for anyone suffering from symptoms of CO poisoning

Symptoms of carbon monoxide poisoning

What causes CO detector false alarms?

A false alarm is when your CO detector alarms and where no carbon monoxide is detected by your engineer. There could be several reasons for this, which can often be easily resolved:

Cause of alarmWhat to do
The carbon monoxide detected did not come from your own appliances but may have seeped through the walls or floor from a neighbour.Check if your neighbours have fuel-burning appliances that might emit carbon monoxide. Carbon monoxide might escape from chimney stacks allowing the toxic gas to enter your premises via a joint loft space.
The replace-by date may have been exceeded.Most CO alarms are only effective for 5-10 years. Once expired, they can sound erratically, or not sound when they should, The expiry date for each unit can be found on the information sticker on the back of the unit.
Excessive moisture from a bathroom may set off your CO alarm.CO alarms can be corrupted by steam, and therefore shouldn’t be installed in bathrooms. If your CO alarm is repeatedly triggered by steam, it may become ineffective, and should be replaced.
Lead acid battery chargers produce hydrogen gas which sets off CO detectors.If you are charging your caravan or boat battery at home, this could set off your CO alarm. Once you have made sure that the alarm is false, it is safe to ignore the alarm in this scenario, but remain vigilant for other signs. If this happens often, invest in a CO alarm with a digital display to assess the level of risk when the alarm sounds.
Freshly screeded floors emit a gas that sets off carbon monoxide alarms.If your floors have just been screeded, and you have made sure that the alarm is false, it is safe to ignore the alarm in this scenario, but remain vigilant for other signs.
The carbon monoxide alarm that you have installed may not be suitable for the type of premisesFor example if it is installed in a caravan, tent, boat or living quarters of a horsebox you will need to ensure that your alarm is Kitemarked to BS EN50291-2. Alarms tested to BS EN50291-1 are only for use in home environments and are not suitable for camping and caravanning.
Smoking indoorsA heavy smoker in a poorly ventilated room the CO from smoking may trigger an alarm. It is recommended to open a window if possible to improve ventilation. If this happens often, invest in a CO alarm with a digital display to assess the level of risk when the alarm sounds.
Homes that are adjacent to very busy roads may experience higher levels of CO in the home when windows are open as traffic fumes may enter the room and set your alarm off.If this causes persistent false alarms, invest in a digital CO alarm, allowing you to see a live CO reading. You can then determine the level of risk. For example, if the reading is high, there is probably a leak. However, if it has just tipped over the threshold due to air pollution, the alarm can be ignored/silenced without having to get an engineer in to check for a leak.
The sound that your alarm is making may not be the alarm sound to alert you that there are dangerous levels of CO present.Most alarms have several audible sounds to indicate things such as low battery warning or that there is a fault with the alarm. Keep the manual safe so that you can refer to it should the alarm go off.

Buying a CO detector

You should have a carbon monoxide detector in every room where there is a solid fuel burning appliance. Only chose CO detectors that have met the rigorous testing standards of the European standard EN50291. These alarms provide peace of mind that this vital alarm has been manufactured and tested to the highest standards. Moreover, investing in a CO detector with a digital display also provides peace of mind, as it allows you to assess the situation when an alarm goes off. This is particularly useful if you have had persistent false alarms due to pollution, smoking, or other external factors, as it allows you to check the reading to assess the level of risk before calling an engineer to check for a leak.

Why is my smoke alarm beeping?

Is your smoke alarm beeping in the night and keeping you awake, or disturbing your day? Whether you have mains powered, interlinked smoke alarms, or battery powered smoke alarms, follow our guidance below to troubleshoot the beeping.

What sound is your smoke alarm making?

Smoke alarm sounding continuously

  • First check there is no smoke or fire in your property
  • Make sure the beeping is definitely coming from your smoke alarm. Other alarms in the property such as a carbon monoxide alarm or burglar alarm could be responsible for the noise.
  • Clean the alarm if it is dusty or dirty. Vacuum around the alarm or use a hairdryer to blow out dust on a cool setting.
Replace by date on the back of a smoke alarm | smoke alarm chirping in the night
Replace by date on back of smoke alarm
  • Check the replace by or manufacture date on your alarm. Smoke alarms usually last for a maximum of 10 years, so if the manufacturing date is approaching 10 years or more than 10 years, it’s time to get a new smoke alarm. Sensors inside the alarm deteriorate after this time causing the alarm to be less effective.
  • Check the position of your alarm. There are different types of smoke alarm suitable for specific locations in your home. Find out more below about positioning your alarm.
  • Your smoke alarm may be damaged or have developed a fault. Exposure to water, fire, grease and certain types of paint can cause a fault to develop. If there is a fault, replace your smoke alarm immediately to protect your home and family.

Smoke alarm chirping intermittently

  • Replace the battery* in your smoke alarm. Ensure you are using the correct battery type and are inserting it the correct way around. If the battery is low, it is more likely to sound at night as a drop in room temperature can impact the battery’s ability to power the alarm.
  • Check the manufacture date on your alarm. Smoke alarms usually last for a maximum of 10 years, so if the manufacturing date is approaching 10 years or more than 10 years, it’s time to get a new smoke alarm. Sensors inside the alarm deteriorate after this time causing the alarm to be less effective.
  • Your smoke alarm may be damaged or have developed a fault. Exposure to water, fire, grease and certain types of paint can cause a fault to develop. If you suspect a fault, replace your smoke alarm immediately to protect your home and family.

How to stop wired alarm chirping intermittently

* All new or recently extended homes should have mains powered, interlinked alarms fitted which also have a back-up battery. Intermittent chirping in mains-powered alarms is often caused by low power in the back-up battery.

Replacement batteries for smoke alarms

Smoke alarms usually require either Alkaline AA batteries, an Alkaline 9V battery or a Lithium 9V battery. Buy replacement smoke alarm batteries as soon as possible to ensure that your family would be alerted to a fire in your home.

Mains powered smoke alarm need replacing?

Whether your smoke alarms are mains powered or battery powered, they should be replaced after 10 years due to a deterioration of the sensors. Battery alarms are easily changed and installed, but how do you replace a mains powered alarm? Most mains powered alarms can be replaced without the need for an electrician if you purchase the exact same model, if still available, or an Easichange® replacement where applicable.

Discontinued smoke alarm need replacing?

If you need to purchase a replacement alarm, but find that your existing model has been discontinued, we have a dedicated collection of replacement smoke and heat alarms. This range consists of models specifically chosen to be the simplest, most direct replacement alarms that can often be installed without the need for an electrician.

Preventing false alarms

The type of sensor an alarm has determines where it should be positioned in the home. False alarms may be due to the wrong alarm type being used in or near a steamy, dusty or smoky environment.

  • Heat alarms are more suited to areas such as the kitchen or garage that are often smoky or dusty. Other types of sensors would be prone to false alarms in these areas.
  • Optical smoke alarms are ideal for bedrooms, living rooms and ground floor hallways.

To avoid causing false alarms or affecting the performance of an alarm, it is good practice to avoid installing alarms in the following locations:

  • Next to a door, window, air vent or fan that would create a draft
  • Outside
  • Anywhere that airflow would be obstructed by curtains or furniture
  • Locations that are steamy or humid such as a shower room

Find out more about positioning your smoke alarm in your home or take a look at our help guides for more information about types of alarm sensor.

Always ensure you act as quickly as possible to change or replace a defective smoke alarm to keep your home and family safe. If you require any further assistance, contact our customer service team on 0800 612 6537 or email support@safelincs.co.uk.

A Guide to Fire Safety in Offices

Fire safety in offices

Who is responsible for fire safety in my office?

If you are the owner, landlord, employer or occupier of a business premises, including offices, you are responsible for fire safety under the Regulatory Reform (Fire Safety) Order 2005, and are known as the ‘responsible person’.  As the responsible person in your office, you must ensure that you:

  • Carry out a fire risk assessment and review it regularly
  • Identify risks from the fire risk assessment and put measures in place to reduce or manage them
  • Inform staff of the risks and of their responsibilities to ensure good fire safety is achieved
  • Ensure adequate fire safety measures have been put in place and maintain them
  • Have an appropriate fire safety procedure and communicate this to staff and visitors
  • Provide training to staff to ensure they know what to do in the event of a fire

What is a fire risk assessment?

A comprehensive fire risk assessment taking place

A fire risk assessment is a detailed review of your office space to identify fire risks and provide recommendations to either mitigate, reduce or manage them. A fire risk assessment can be carried out by a competent person or a professional.

You can use our free fire risk assessment form to carry out your own assessment if you feel you have the required skills and knowledge to do so. It is essential that you use this in conjunction with the appropriate official fire risk assessment guide for offices.

Alternatively, you can request that a trained fire risk assessor completes your office fire risk assessment for you. You will receive a comprehensive fire risk assessment and detailed guidance should any recommendations for improvement be required.

More information:

What kind of fire safety measures will I be required to put in place?

To ensure that you are meeting all your legal obligations you will need to look at the following areas:

  • Are your emergency evacuation routes and exits clear from hazards and well signposted?
  • Do you have adequate means to detect a fire and warn others?
  • Do you have appropriate fire fighting equipment and is it in the right place?
  • Are any dangerous substances stored correctly?
  • Think about the people who are in your office (both staff and visitors), particularly those with special considerations such as the elderly and people with disabilities
  • Provide fire safety information and training

Emergency evacuation routes and exits

Photoluminescent fire escape route signs

Staff escaping a building must be visually directed to the safest and usually quickest route leading to the nearest fire exit. Ensure that photo-luminescent (glow in the dark) fire escape route signs are indicating the nearest exit and are clearly visible.

You need to ensure that even if the mains power fails, all escape route signs are visible and that stairs and uneven floors are lit sufficiently to escape safely. You can achieve this by installing emergency lights or by installing illuminated fire exit signs in the first place.

More information:

Evacuation and fire drills

Every member of staff must be made aware of where the nearest fire exits are and which routes to take when exiting the building. The best way of ensuring that all staff know the escape routes is to ensure that when a new staff member starts you complete a ‘fire walk’. This enables you to show staff all the fire escape routes and  where fire fighting equipment is located.

You should carry out regular fire drills, ensuring that you also include practising taking alternative routes if your nearest fire escape should be blocked by a fire.

When planning your evacuation procedure ensure that you also include how you would safely evacuate someone with reduced mobility. Evacuation chairs offer a safe and easy solution to ensure that everyone can escape safely in the event of a fire. You should ensure that staff are trained to use equipment and also that the evacuation equipment is maintained and serviced. 

Fire extinguishers and maintenance

Choosing the right type of extinguisher

Portable fire extinguishers can be very valuable in preventing small fires getting out of hand and turning into large fires that can put lives at risk and destroy buildings. The safety of your staff and visitors should be the main priority and staff should only be encouraged to use a portable fire extinguisher if they have been trained and as long as it does not put them in any danger.

Dry water mist fire extinguishers can be used on live electrical fires

It is paramount that you have the correct type of fire extinguisher to tackle the type of fire that could occur in your office. Installing extinguishers that can tackle more than one type of fire, such as the dry water mist fire extinguisher, will reduce the number of different types required in your office and will also reduce the risk of using the wrong type. Dry water mist extinguishers can be used on class A, B and C fires as well as on live electrical fires.

More information:

If you are still unsure of which type of fire extinguisher you need in your office you can book a fire extinguisher site survey.

Installing extinguishers

Ensure that your extinguishers are commissioned and installed by a service engineer at your premises. You will need the correct signage and to ensure that they are hung in the correct location.

Extinguisher maintenance

Once your extinguishers have been installed you are responsible to ensure that a monthly visual check is carried out, looking for the following:

  • Are there any signs of damage to the exterior?
  • Are there any blockages in the hose?
  • Are there any signs the extinguisher has been tampered with?
  • Is the extinguisher pressurised?

More information:

You must also ensure that an annual service of the extinguisher has been carried out by a trained engineer and in accordance with the British Standards.

Please note that where self-maintenance extinguishers are installed, a yearly visual inspection by your staff is required, which must be documented in your fire safety log book but no annual visit is required by an external engineer.

Fire alarms and manual call points

As the responsible person you will need to ensure that there is an adequate fire detection system in your offices. A common way to achieve this is to install fire alarms. The size, configuration and use of your office will define what sort of fire alarm system you require.

More information:

Make sure that all employees understand that the first thing to do if they discover a fire is to press the nearest manual call point (also called manual break points). This alerts all of your staff of the fire. New staff must be shown the call points during their induction period.

Where office buildings are shared with other companies, make sure that a system is in place for notifying all the companies in the building in the event of a fire.

Free fire safety log book

We offer a free online log book with custom reminders and the ability to print it if you wish to keep a hard copy. Keeping an online log book will ensure that it is protected in the event of a fire so that you can show your due diligence and compliance.

It is essential that you keep a record of all your fire safety checks and fire drills in a fire safety log book.

Lighting the Way – Emergency Lighting Requirements

What you need to know about emergency lighting

Why is emergency lighting necessary?

As the responsible person it is your legal obligation to ensure that adequate emergency lighting is installed across all the escape routes and exits from every area of the building with a minimum backup duration of between 1 and 3 hours. Emergency lighting is essential to light escapes routes for emergency evacuations when normal mains-powered lighting fails.

Eden Bulkhead Emergency Lighting
LED Emergency Lighting Bulkhead – Eden

There are different types of emergency lights, some function as a normal light and others function only as an emergency light source. As a starting point you should know what type of emergency light you want to install for example; do you want a maintained emergency light (stays on constantly) or a non-maintained emergency light (illuminates only in the event of a mains power failure)?

Where to install emergency lights and signs

When deciding where to install emergency lights, take into account any hazards that there may be along the evacuation route, such as corners, stairways or uneven flooring. You must also ensure that fire alarm call points and equipment used for firefighting, such as extinguishers or fire blankets, are adequately illuminated to be easily seen or located. Some areas will require continued operation (e.g. a chemical processing room, operation theatre etc); higher continued lighting requirements must be considered in these areas.

Jalite photoluminescent fire exit signs
Jalite photoluminescent fire exit signs

A sub-category of emergency lighting is fire exit signs, which are green ‘running man’ signs with arrows that guide people towards the nearest exits. These are either internally lit in the same fashion as space emergency lighting or, in case sufficient other emergency lights are available, they can be photoluminescent. Such ‘glow-in-the-dark signs store energy from either natural or artificial light and releases this stored energy when the light source is no longer there, emitting a yellow/green glow to illuminate the text on the sign.

You should refer to your fire risk assessment to ensure that you have covered all the essential fire escape routes and addressed any hazards on your site that were highlighted in this assessment. It is a legal requirement to carry out a fire risk assessment and you should refresh this assessment if the activities within your premises change or if significant changes to the layout are made. You can find authoritative guidance in the government's fire risk assessment guides.

Buy emergency lights

Visit our emergency lights and signs section to view our full range of emergency lighting products.

Testing and maintenance

As with all fire safety equipment, regular testing of your emergency lights must be carried out to ensure that it is working correctly. You should test that the lights are triggered when the mains supply is cut, and also that all the lights are illuminated as they should be. This can be done with the use of a fish key.

You will need to test your lighting once a month and ensure that a full discharge test is carried once a year. Log the results as any other fire safety equipment tests in your fire safety logbook.

If you would like to know more about emergency lighting our emergency lighting guides can provide you with useful information.

Maintained or Non-Maintained Emergency Lighting?

The use of maintained or non-maintained emergency lighting should be decided based upon building type, its occupants and purpose or usage.

What is the difference between maintained and non-maintained emergency lights?

Maintained Lights

Maintained emergency lighting is on at all times. Maintained emergency lights are mains powered and used as part of the normal room lighting system. But, in an emergency situation when mains power fails, it will continue to stay lit for a specific duration powered by a back-up battery. It is generally used in non-residential places of public assembly such as leisure centres, cinemas, shopping centres etc. In public venues where the normal lighting system is often dimmed, for example cinemas, theatres or bars, maintained luminaries are always required.

Maintained lighting could include lit fire exit signs, bulkhead lighting or recessed downlights. There are LED options available which will reduce energy consumption and therefore running cost.

Non-maintained Lights

Non-maintained lighting usually only comes on for a specific duration when the power supply to normal artificial lighting fails. Non-maintained emergency lights are normally suitable for workplaces which are usually lit when occupied. Non-maintained light fittings are powered by a battery that is charged from a constant trickle of mains power. This battery should have enough charge to remain lit for a duration of 3 hours or more if mains power fails.

Illuminated fire exit sign next to a door

Which type of emergency lighting do I need?

British Standards guidelines 5266-1:2011 requires adequate emergency lighting to be installed in all high occupancy residential, public or commercial buildings. There are often more specific recommendations given by local authorities in each area.

Whether maintained or non-maintained emergency lighting is needed is largely a question for fire risk assessors based on each individual circumstance. If non-maintained lighting is deemed sufficient, it is also worth considering the reduced environmental impact and lower energy cost of using non-maintained lighting over time.

Watch our video to learn the difference between maintained and non-maintained emergency lighting

Can an emergency light fitting be both maintained AND non-maintained?

Yes. Maintained emergency light fittings or signs used as part of a normal room lighting system can also be wired to perform as a non-maintained fitting if required. Many maintained fittings are available as switchable units, meaning they can be switched between maintained and non-maintained modes using an ordinary light switch. Non-maintained light fittings cannot be wired for use in maintained operation.

Still unsure which type is most suitable?

If you are unsure which emergency lighting is best for your environment, it is best practice to conduct a fire risk assessment. A risk assessor will advise the most suitable option in line with the regulations.
