—removable air filter elements applied to the front side parts of the mask; —inhalation and exhalation valves applied to the front zone of the mask, in front of the mouth, when the mask is worn; —elements for securing the mask to the face; —an electronic nose device adapted to provide, when worn by the person, time-related data about the quality of the air in the working environment; —a breathing detection device, adapted to provide, when worn by the person, time-related data about the respiratory rate; —a data processing and displaying device, adapted to receive and store the data outputted by the protective facial mask, electronic nose device and breathing detection device, also adapted to process and display the data in order to determine a condition wherein the protective facial mask needs to be worn. ## Claims ### Claim 1 A multi-sense system adapted for prevention of occupational diseases in a working environment, comprising: a protective facial mask, adapted for application in the front zone of a person's face, comprising nose and mouth areas, and comprising: a temperature and humidity sensor adapted to be activated when the mask is worn, and adapted to provide time-related data concerning said activation as well as temperature and humidity values; removable air filter elements applied to the front side parts of the mask; inhalation and exhalation valves applied to the front zone of the mask, in front of the mouth, when the mask is worn; elements for securing the mask to the face; an electronic nose device adapted to provide, when worn by the person, time-related data about the quality of the air in said working environment; a breathing detection device, adapted to provide, when worn by the person, time-related data about the respiratory rate; a data processing and displaying device, adapted to receive and store the data outputted by said protective facial mask, electronic nose device and breathing detection device, also adapted to process and display said data in order to determine a condition wherein said protective facial mask needs to be worn. ### Claim 2 (depends on 1) The system according to claim 1, wherein said elements for securing the mask to the face comprise a seal applied to the rear edge of the mask, to ensure adhesion thereof to the face, said seal being made of thermoformed fabric material padded with soft foam. ### Claim 3 (depends on 1) The system according to claim 1, wherein said electronic nose device (3) comprises a VOC value sensor, and said time-related data about the quality of the air are data concerning the VOC value. ### Claim 4 (depends on 1) The system according to claim 1, wherein said temperature and humidity sensor comprises an activation switch adapted to generate said time-related data concerning said activation. ### Claim 5 (depends on 1) The system according to claim 1, wherein said data processing and displaying device is adapted to generate said data displays of a first type concerning the number of times that said mask has been worn and not worn, and indicating when a threshold value of said VOC value has been exceeded. ### Claim 6 (depends on 1) The system according to claim 1, wherein said data processing and displaying device is adapted to generate data displays of a second type relating to a graphic organization of said time-related data about the number of times that said mask has been worn and not worn, said quality of the air, and said respiratory rate. ### Claim 7 (depends on 1) A method of using said multi-sense system according to claim 1, the method comprising the steps of: providing said electronic nose device and said breathing detection device worn by a person; sending the data generated by said electronic nose device and said breathing detection device to said data processing and displaying device; using the data sent to said data processing and displaying device to determine a condition wherein said protective facial mask needs to be worn.
