Most fire extinguisher manufacturers have models listed for various household uses. Most commonly available home fire extinguishers are suitable for household use. The letters represent the type of fire that the extinguisher is intended to combat. The numbers represent the amount of fire that the device is intended to extinguish. Thus, the higher the number the more fire it may put out.
Most extinguishers advertised for home use are acceptable and are readily available.
They may be found at hardware stores and home improvement stores and mass merchandisers. Simply go the nearest fire station and let the personnel know that you would like your blood pressure checked. They will provide this service to you at no charge. I have just moved to York County and my insurance company wants information. They want to know the distance to the closest station and if it is staffed around the clock.
