While this is the standard code, the advice of a building professional or fire safety authority is essential.

The best way to determine the type of fire extinguisher, the fire extinguisher mounts, and the exact number of fire extinguishers that need to be installed in your commercial space is to have a fire protection contractor come out to inspect the building and recommend the actual amount needed.

It is also important to consider the right number of fire extinguishers in your commercial premises. It should be chosen to be easily accessible to both your employees and customers without harming any of them.

How should high fire extinguishers be mounted on a business premise?

The standard height for any fire extinguisher mount is between 3 and 5 feet above the ground. This helps prevent fire extinguishers from being hit, removed, or damaged.

They should be mounted on brackets where the handle is 3 to 5 feet above the floor level.

Larger extinguishers, however, must be mounted at a lower height because of their weight, and the handle of the mount should be about 1 to 2 feet above the ground.

How to detect a fire early in a business premises

It’s pretty easy to spot fire in a commercial space, only if the space is small. But what if it’s a large place? How do you recognize fire or the triggers of fire?

The natural way is through the sense of smell (sound). So, for example, you can detect the smell of a burning substance or smoke with this complex human organ. But this is actually not the best way.

Technology has made it much easier with the introduction of smoke detectors.

Remember the well-known saying, “No smoke without fire.” This means that some amount of smoke precedes most fires.

A smoke detector will help detect fire even if your sense of smell cannot.

As soon as this smoke detector detects a cloud of smoke, an alarm will sound to notify you, giving you enough time to make your decisions.

Now you need to install this fire alarm device anywhere on your business premises. It costs less but saves more.

How often are fire extinguishers to be checked?

The frequency with which a fire damper should be inspected and maintained is fundamental. Every 31 days, you need to manually and physically check all of your fire extinguishers. Always check the extinguishers for signs of corrosion, damage, leakage, or clogging; make sure the extinguishers are still in place, and their labels are still intact.

Where to mount a fire extinguisher in a commercial building

Fire extinguishers are placed where they are within easy reach of everyone in case of an emergency. Remember, you need more than one fire extinguisher on each commercial building floor 30 to 50 feet apart.

Fire extinguishers are mounted and secured using fire extinguisher brackets or mounts.
