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

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

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 iss

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 tr

Hi Lori what make and model is this, please? Harry

Hi Sam Here a link to the replacement alarm for Ei151. Harry

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

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

Hi Pete, what alarm model do you have? If not sure, can you please send a photo? Harry

With it getting colder at night your backup battery is probably running low giving you a low battery warning. Or your alarm is getting too old (more than 10 years). Step 1: check the age of the alarm. You can find the date on the side or back of your smoke alarm. If it's older than 10 year, you need to replace. Step 2: make sure the backup battery has enough power left Step 3: if none of the above, vacuum the alarm thoroughly to get rid of spider webs etc Step 4: if the above has not helped replace the alarm Harry

Hi, I would guess that it was triggered by the steam from the bath. Most CO or smoke alarms do not work reliably in a bathroom due to the high moisture. Still, worth checking the appliances just to be sure. Harry

Hi Please check replace-by date on the CO alarm to make sure it is not just getting faulty. With both fire alarm and CO alarm in the unit going off, it is unlikely to be a CO leak. However, should the alarm still be in date and the batteries in working condition then you might have to look further into your fuel burning appliances. Harry

Dear Sir/Madam Two possibilities: 1) your power supply does not reach the alarm unit (wrong or interrupted wiring). You can exclude this possibility by switching heads with one of the other units. If the replacement unit also beeps there is a power supply issue. 2) if there is a technical fault the alarm needs replacing. Please contact your seller for an exchange under warranty. Harry

Hi Toni You need a free-swing fire door closer. For example the Fireco Freedor fire door closer and retainer allows the door being used like any normal door but will trigger an integral door closer when a fire breaks out. Harry

Hi, smoke alarms should be replaced every ten years, as beyond that the sensors start to deteriorate. So you were lucky so far. Harry
