In order to provide a real-time volatile organic compounds canister management tool for the users and managers, a respirator waring device for replacement timing of volatile organic compounds canister has been developed that is capable of the following: (1) detecting breakthrough condition of canister; (2) reducing carbon dioxide effect of the measurement by installing between the canister and the mask respirator; (3) not increasing the burden on the user's breathing; (4) defining canister breakthrough conditions; and (5) providing vibration, LED indicator warning functions, and operating for more than 8 hours.
Respiratory protective equipment is the last line of defense to protect workers. However, most respiratory protective equipment cannot warn users and managers that the filter material has reached saturation, prompting managers or users to replace new respiratory protective equipment or canister. In order to provide a beneficial useful real-time management tool for users, the device integrates a miniaturized gas detector and an alarm device, and constructs a volatile organic compounds canister measurement module is constructed to monitor the breakthrough conditions of the respiratory protective equipment in real time. When the canister is saturated, the user is reminded to replace it, which improves the convenience and safety of workers using respiratory protective equipment and meets the practical needs of special fieldsspecial/particular areas or fields.
