Apart from the usual fire extinguisher services, as required by law, I would say that you must also ensure that all your fire extinguishers are installed properly. While repairing your equipment, you can ask the service technician how you should install the unit to the wall.
Extinguishers must be attached to the wall so that the handle is one meter from the floor. For smaller equipment, the distance must be about 1.5 meters from the floor. You can also get the best fire extinguisher service via www.tmservicesltd.co.uk/services/fire-extinguishers
A specialist fire safety service technician will know these things, but you should check for simple things yourself. This will save time for engineers to do more important things.
For special interests such as people with disabilities, you can make adjustments, but the device must remain outside the floor. Extinguishers must be close to the exit, and in shallow recesses, away from extreme heat.
After installing it, you can ask the fire technician for advice. The most important thing to remember is that the time and cost of applying safety equipment once a year is far less than the potential cost of not doing it.
You must always be vigilant about the security of your building, and your employees and fire services can save your life once a year.
In conclusion, if you install your fire equipment properly, it will last a long time and is easier and safer to use. Regular fire services are needed, so think about it first, and save yourself from big problems later.
