How to Wear Protective Clothing Correctly

Protection is a system where only suitable protective clothing is not enough. There must also be other protective gear that matches the level of protection. We often see such a scene: In the same dangerous environment, rescue workers wear a wide variety of protective gear, both wearing chemical protective clothing, but also wear firefighting clothes, wearing gas masks, but also there is no breathing protection . At this time should ensure that the personal protection system between the various equipment matching, because the overall level of protection is determined by the weakest aspects of the equipment. Therefore, when wearing chemical protective clothing, must be equipped with the necessary protective equipment as needed: such as gloves, masks or respirators, anti-chemical protection boots and so on. After wearing the airtight protective clothing, the wearer will be in an isolated environment. Therefore, to equip the necessary communication equipment, mask fogging measures, cooling measures (such as ice vest) and so on, the relevant protective equipment should be considered fully, otherwise it may make the wearer at risk.
