How to Calculate Your m²/ft²?

How to Calculate Your m²/ft²?

It’s actually very easy to calculate how many square meters or foot an area is, whether it is a simple rectangle or more complex shape. When dealing with a simple rectangle, just multiply the length by the width for your total square meterage or footage. If you’re dealing with a more complex shape, treat each area as a rectangle and perform the same calculation. Then combine the square meterage or footage of each area for to get the total area.

Common Questions 

What is a Respirator Mask?

A respirator mask prevents harmful particles, fumes, and substances from entering the respiratory tract. Therefore, preventing damage being caused to the nasal cavity, pharynx, larynx, trachea, bronchi, and lungs.

These masks are necessary for certain conditions, such as when using certain materials and working in confined spaces. This is as materials such as insulation or asphalt can discharge harmful particles and fumes when being used.

There are strict regulations around the use of respirator masks governed by the Health and Safety Executive. These ensure that the equipment is CE marked, correctly fits the wearer, and offers protection in the environment they are working in.

What is an FFP1, FFP2 and FFP3 Mask?

FFP masks are available in a variety of grades, with each being designed to filter different concentrations of impurities in the air. In the UK, the most popular type is FFP2 due to its filtering <95% of harmful substances. 

FFP1 Respirator Mask

An FFP1 mask protects against materials with a concentration of up to 4x OEL or 4x APF. Because of this, they are the lowest priced FFP respirator mask.

FFP2 Respirator Mask

An FFP2 mask protects against materials with a concentration of up to 12x OEL or 10x APF. As a result, this is a mid-priced FFP respirator mask. 

FFP3 Respirator Mask

An FFP3 mask protects against materials with a concentration of up to 50x OEL or 20x APF. As you would expect, these are the costliest type of FFP respirator mask.

Are Dust Masks Reusable?

In the majority of cases, a dust mask can be reused until it is dirty, damaged, or contaminated. If your mask features a valve or filter, you will likely be able to replace this rather than purchasing an entirely new mask. However, this is all dependent upon the recommendations of the HSE and manufacturer.
