For A Fire Extinguisher Massachusetts Is The Way To Go

By Scott McDonald


A fire extinguisher, often referred to simply as an extinguisher is an active fire protection equipment used for extinguishing or controlling small fires. They are usually used in emergency situations. These devices are meant for use in minor situations only as opposed to out-of-control situations where fires have reached the ceiling. When in need of a high quality fire extinguisher Massachusetts is the best location to check out.

Typically, these devices consist of cylindrical pressure vessels that store the firefighting agent, which is released during operation of the device. Some devices do not have cylindrical vessels, although such models are less common. In many countries around the world, the requires industrial and commercial buildings to be installed with some sort of firefighting device.

Annual inspection and servicing of all extinguishers installed in buildings is required in most jurisdictions. The inspection may have to be done more regularly in some places. There is a mark that is placed on the device to show the kind of service carried out by the service company. Services carried out usually include replacement, inspection, and recharging among others.

Generally, there are two kinds of extinguishers in use currently. The two types are cartridge-operated and store-pressure models. In stored pressure gadgets, the firefighting agent and the expellant are stored within the same chamber. Propellants vary with the kind of agent used. Nitrogen is the main propellant used in dry chemical extinguishers. On the other hand, air is used in foam and water extinguishers. Stored pressure varieties are more common than cartridge-operated models.

In cartridge-operated extinguishers, expellant and extinguishing agents get stored in separate containers. The expellant is exposed to the agent by puncturing the cartridge. The use of cartridge-operated extinguishers is often limited to industrial applications where they are used more regularly than average. Their simpler and prompter use makes them better over the other model. It takes a comparatively shorter time to discharge and recharge the device than store pressure devices.

Compressed carbon dioxide is the propellant used in cartridge-operated models as opposed to nitrogen which is used in the other variety. In the US, the cartridge-operated model comes in various forms including foam, water, dry chemical, wetting agent, and dry powder. Another classification of extinguishers has two other types, that is wheeled and handheld extinguishers. Wheeled extinguishers are also known as cart-mounted extinguishers.

Handheld models are usually very light, weighing between 0.5 and 14 kilograms. The light weight makes them easily portable. The wheeled varieties are usually relatively heavy, weighing over 23 kilograms. The wheeled models are commonly found at airport runways, docks, marinas, heliports, and construction sites among other sites. They have handles for use to pull them from location to location.

Handheld devices are meant for installation in buildings in places where one can access them easily. Typically, they are placed against walls in places where people frequent. Most jurisdictions have made it mandatory for the devices to be installed in aircraft, watercraft, and automobiles. How high on the wall the device is installed is governed by the fire department.
