Anti-Filtration of Aniline Harmful Gases by Xinhua Chemical Technology Grade 3 Gas Filtration Tank

Self-priming filter for gas mask

First,purpose

When complying with all instructions, restrictions and applicable safety and health regulations, the filters and air filters can be used in conjunction with full or half masks of self-priming filter gas masks to provide limited respiratory protection in the corresponding air pollution areas.

Not applicable to:The concentration of pollutants is too high or unknown.

Not applicable to:The oxygen content in the air is lower than that in the air.18%Environment, escape from underwater operation and fire protection zone.

Not applicable to:Closed working environment, such as wells, tanks or relatively sealed environment.

Three.Instructions

1Before use, please read this manual carefully to check whether the type of filter is consistent with the protective gas in the polluted area, and check the connection between the filter and the mask. Users are obliged to conduct pre-job training for users.

2The filter is easy to absorb moisture. It is not allowed to open the package, unscrew the lid or the bottom plug before use. The filter is not recommended to be reused.

3Due to the influence of temperature, humidity and pollutant concentration in the polluted area, the protection time of the filter is only used as a reference value. If you smell odor or dizziness, nausea, dyspnea, etc., you should immediately evacuate the polluted area and check or replace the filter or respirator.

4Special attention should be paid to the protection of colorless, odorless and harmful gases (such as mercury, carbon monoxide, etc.) and they should be accompanied by operations.
