  1. Hi, can you please send a photo of the alarm so we can help? Thanks
  2. Hi There is a help video about how to remove the Firex/Kidde alarms which should apply Harry
  3. Hi Natalie, what is the replacement date on the unit, please? Kidde CO alarms last for ten years, usually. Harry
  4. Hi PaulRob, you could consider Britannia P50 service-free extinguishers which only get re-filled every ten years, which would halve your powder waste. Instead of annually calling in an external engineer your own employees would carry out an annual visual inspection, which is recorded on the back of the extinguisher. The visual inspection involves checking the dual gauge display and in your case nothing else, as there is no risk of vandalism in your company. We would be happy to give you a demonstration and visit one of your sites with you to talk through the P50. More information about the P50 extinguishers. Harry, Safelincs Ltd
  5. Hi Hayfever The launch of a Britannia P50 with de-ionised water mist is getting closer. These extinguishers should be ready by the end of the year. They will combine two important technologies: Service-free extinguishers with de-ionised water mist. Watch this space! Harry
  6. Hi Manu CO2 extinguishers are really only suitable for electrical items and the risk is that the fire might re-ignite once the short burst of CO2 has dissipated. This is particularly the case if the electricity is still live. The main health risk is actually, and surprisingly, not asphyxiation (absence of O2) but poisoning with CO2. Just 4% CO2 in your air has already a health impact and 8% leads to unconsciousness and death. Not many fire safety specialists are aware of this. So, CO2 must be avoided in small spaces. For electrical risks up to 1000V (domestic is 230V) water mist extinguishers with de-ionised water are the best choice for domestic (and business) applications. They are broad spectrum, cool the fire and minimise the residue from the fire and the fire fighting action. The de-ionised water is of course non-conductive. Harry

    Hi Rich, good questions, thanks While the P50 wet chemical has not been tested and rated for Class A fires, like most other wet chemicals the extinguisher has a good capacity to extinguish Class A fires such as a waste bin fires. Wet chemical extinguishers contain around 60 to 70% water which gives them a decent Class A capability, although their focus is, of course, fats and oils. BS 5306-8:2012 9.2 Note 1 specifically states that Class F extinguishers can be suitable for other fire classes. EN3-7 requires all Class F fire extinguishers to be di-electrcially tested to 35,000 Volt. The P50 wet chemical is therefore, of course, also fully di-electrically tested and can be safely used on live electrical equipment up to 1000 Volt. A safety distance of a meter needs to be maintained. No other extinguisher types should be kept near deep fat fryers, as only wet chemicals are safe on deep fats and oils. Harry

    Hi Hayfever Thank you for sharing your experiences. Assuming that there is no application with more than 1,000 Volt and no special risks present (eg deep fat fryers, which require wet chemicals) the message should be 'use P50 extinguisher provided on all risks but do not get closer than 1m' , as the P50 foams are tested for electrical safety with 35,000 Volt at 1m distance (the difference between 35,000 and 1,000 Volt being the safety margin!). If you offer CO2 on top of P50 (or in fact any) foam, there is a risk that the users are not sure which extinguisher to use on which type of fire. Not knowing what type of estate you are representing makes is difficult to narrow the reference list down, however, P50s have now been installed for over 8 years and are installed at universities, supermarket chains, refineries, large farm groups, warehouses, insurance offices, schools, all Scottish Courts and many other type of businesses and Housing projects. If you want to contact me directly I am happy to put you in contact with customers that are relevant to you. With larger estates we have in the past offered a gradual change over: One site is converted completely to P50 and any in-date traditional extinguishers are taken out and stored and then moved to other sites of your estate (still with traditional extinguishers) that require replacements. That way you have fully converted sites without a confusing multitude of extinguishers while you are not destroying the residual value in your traditional extinguisher stock. Harry
  9. Hi Luke The British Standards are suggesting a minimum of 2 extinguishers, however, BS standards are just recommendations. You have to use a dose of common sense and such a small space would be well covered with the suggested foam extinguisher. That is if you are a standard shop or office. If you store flammable liquid etc you would need professional advice. An extinguisher needs to be big enough to extinguish a small fire reliably, so the P50 foam in the 6ltr version should be suitable. Harry
  10. Hi, clearly you have either carbon monoxide or other gases in the vicinity that trigger the CO alarm. The first step has to be to search for a source of carbon monoxide. Do you have gas/oil/solid fuel appliances? Do your neighbours have such appliances? If this is not the case you need to check whether you have acid-lead battery chargers nearby or whether there is fresh floor screed. Both create gases that can trigger CO alarms. Most likely the CO alarms are doing their job and warning you of this dangerous gas. You need to leave the building and get a specialist to fix the issue. Further information about CO dangers can be found on https://www.safelincs.co.uk/carbon-monoxide-information/ Harry

    Hi Meady Certainly a good question to start a lively discussion with! Safelincs is, as you are probably aware, a strong supporter of the P50 service-free extinguishers (despite Safelincs also offering nationwide extinguisher servicing for traditional extinguishers). We were amongst the early adopters when these were launched in 2012. We see them as a way for customers to reduce maintenance costs and for the environmental impact of extinguisher provision to be reduced: The P50's chemicals only need replacing after ten years instead of the normal 5 years and there is no maintenance traffic clogging up our highways. Here a quick overview for newcomers: The P50 is a kitemarked portable stored-pressure extinguisher manufactured in the UK and is made from various non-corroding components, such as an inner plastic pressure cylinder encased in spun aramid fibre (similar to Kevlar). It does not corrode, the lining cannot become detached and start attacking the extinguisher's chemicals and the cylinder can be heavily deformed without losing pressure. It also features duplicate magnetic pressure gauges. Because of these features the traditional servicing activities (check for pressure loss with a gauge pump, check for dints, internal and external corrosion, dropped inner linings etc) are not required. Instead, the customer visually inspects the extinguishers (check the gauges show green, double check one gauge with a magnet, visually check the hose and body) and records the inspection on the extinguisher itself and in the customer's logbook. When a customer orders P50s, Safelincs carries out a site survey (all our engineers are BAFE approved), installs the required number of extinguishers and trains staff in the visual inspection process. This training is also certified by us. However, as there is no engineer's visit for the next 9 years, the extinguisher is classified as 'service-free'. I had the great pleasure of sitting in one of the industry's working groups that cover extinguisher servicing standards, including the various parts of BS5306. Some of the key parts of the standard deal with the servicing of extinguishers. The industry has still not managed to include the P50 and its specific customer-driven visual maintenance regime or refill cycle into the standards. This might well be linked to the fact that many of the organisations that feed into the relevant BSI standard-writing committee are extinguisher servicing companies. Many see the P50 as a threat, as it can reduce their servicing income. P50s can now be found everywhere: Insurance offices, supermarkets, universities, colleges, churches, all Scottish courts, schools, public bodies and even refineries. They are endorsed by many bodies such as the Boat Safety Scheme, London Fire Brigade as well as insurances such as the NFU, the Ecclesiastical Insurance Group and others.

    Hi Sam Here a link to the replacement alarm for Ei151. Harry
  13. Hi First step is to see how old your CO alarm is and whether it needs replacing. Different brands' CO alarms work between 5 and 10 years. There should be a 'replace by' sticker on the unit. Second step is to make sure the batteries are still working correctly. If the CO alarm has replaceable batteries, these might need replacing. Other factors that can set off a CO alarm include boat/car batteries being charged nearby or new floor screed. Harry
  14. Hi Sean, you probably have an ionisation smoke alarm installed (eg EI141 or Ei161). You need the optical version. Simply exchange them on the same base. Here the replacement optical Ei smoke alarm. Harry
