, Description:A FACE SHIELD FOR PROTECTION FROM ENVIRONMENTAL HAZARD
BACKGROUND
[0001] Embodiments of the present disclosure relate to a health protection apparatus and more particularly, to a face shield for protection from an environmental hazard.
[0002] A face shield is a personal protective equipment (PPE) which aims to protect a wearer's entire face or part of it from one or more environmental hazards such as flying objects, road debris, chemical splashes in laboratories or in industry or one or more potentially infectious particles or pathogens. Generally, the head of the wearer with the sensitive sensory organs, namely eyes, mouth, nose and ears is particularly vulnerable. In order to get protection from such environmental hazards or potential infections, it has become essential to wear the face shield for avoiding one or more significant health risks or damage. The face shield protects the worker from being accounted but sometimes also unnecessarily hinders the workflow due to uncomfortable design. As a result, various types of face shields according to comfort and requirement of the user are designed for different working areas.
[0003] Conventionally, the face shield which are available for the user against virus or environmental hazard protection includes a hanging cover like structure to cover the face of the user. However, such a conventional design of the face shield tends to leave space between the face of the user and a boundary of the face shield and as a result permits entry of one or more particulate matters or the one or more pathogens. Also, such a conventional design of the face shield causes discomfort to the user when it is worn for a longer period of time. Moreover, such a conventional design of the face shield creates difficulty in breathing during talking or drinking while wearing the face shield by the user. Furthermore, an identity of the user while wearing the face shield also changes which further creates difficulty in face recognition of the user.
[0004] Hence, there is a need for an improved face shield for protection from an environmental hazard in order to address the aforementioned issues.
