INDUSTRY INSIGHT
On many construction sites workers are issued with disposable dust masks or Filtering Face Pieces (FFPs), however finding a design of FFP mask that will fit most face sizes can be challenging. To overcome this problem, Dräger carried out customer research on a single-use dust mask, speaking to 36 customers across seven countries, and benchmarking 16 products, with 50 participants in total, taking into consideration a wide range of face shapes and sizes. The faces of the participants were mapped using a grid system, which looked at the face width, length, depth and mouth width. Analysis of this information led to an innovative design approach which focused on a three-fold model, providing greater flexibility in both height and width. This, combined with easy-adjustment capabilities, a flexible nose clip and soft wide nose pads, ensured the mask could be effectively positioned, stayed in place and securely sealed the nose area. In addition, it was found that developing masks in two sizes would accommodate the majority of different face shapes and sizes, and extensive testing showed a 96 per cent pass rate in face fit test procedures using this design.
Powered Air Purifying Respirator (PAPR)
Of course, a wide range of other issues beyond face size and shape also affect whether a particular piece of RPE is suitable for the individual wearer. Wrinkles, moles, warts, deep cuts, scars, piercings, facial hair and medical fitness reasons can all impact the provision of respiratory protective equipment. For these groups, a mask is often not an option, so a different approach is needed. In such scenarios, a Powered Air Purifying Respirator (PAPR) is a good solution. Such devices can be used with a range of different head pieces appropriate for the task required, and these can often provide additional benefits as they will not only accommodate different head and face shapes and sizes as well as individual characteristics such as facial hair, but they can also contain additional head face and eye protection,
negating the need to worry about compatible PPE. Therefore, many workplaces looking for more flexible and inclusive RPE – including those in the construction sector – are turning to PAPR as a more adaptable and straightforward solution, without any compromise on safety.
