Respirators are used as a last line of defense against hazardous airborne particles and gases. When respirators are needed, wearers must perform a fit check before donning their facepiece to ensure a seal is achieved and the equipment can work effectively. However, existing fit check procedures are subjective and unreliable, putting lives at risk.
Used in conjunction with an approved Fit Test program the QuantiCheck system scientifically measures pressure in the mask to ensure that an adequate seal has been made and alerts the wearer. The system checks not only the face seal but the whole mask system for breaches or integrity issues that could cause leaks during use.
– Industrial Design
– Regulatory Compliance
OHD approached Design Reality with a clear problem: due to the subjectivity of the testing process, mask wearers were passing daily fit checks when their masks were not fully sealed. Our brief was to create a product design utilising sensor technology, which could identify leaks within tight-fitting respiratory protection equipment, without hindering the performance of the mask in any way.
With twenty years of design experience within the PPE and respiratory protection equipment (RPE) industry, we have a sound knowledge of RPE available on the market. This helped us to understand the best places to position test devices to maintain optimal user interface and ease of testing.
Our electronics team created sensor technology which can identify a drop in the pressure within the mask during a standard fit check procedure. A loss caused by something as small as a hair under the seal could now be identified to the user.
A green light indicates an adequate seal has been made, whilst a red light indicates a seal breach.
With an increased demand for Health and Safety monitoring, we created an app to integrate with our FitCheck® Technology. This means that users and employers can store and review test results, enabling them to demonstrate ongoing health and safety compliance.
Our team created the app utilising UX experience and secured a listing on both Android and Apple platforms for the client.
Testing and Certification
As part of our consultancy services, we ensured the product was fully tested and certified. We helped OHD with completing the product’s EMC, radio and safety testing as well as regional certification.
The Fit Check system, of which QuantiCheck is built upon, has gone on to win multiple awards for its innovation, design and contribution to safety in the workplace.
