Two, how to wear the correct protective clothing
Protection is a system, only the appropriate protective clothing is not enough, but also must have with the performance of the level of protection to match the other protective equipment. We can often see such a scene: in the same hazardous environment, rescue personnel protective equipment worn by a variety of, both wearing chemical protective clothing, but also wear firefighting clothing, there are wearing gas masks, there is no respiratory protection. At this time should ensure that the individual protection system between the matching of equipment, because the overall protective effect is determined by the weakest equipment link. Therefore, when wearing chemical protective clothing, it is important to be fully equipped with the necessary protective equipment according to the needs: e.g. chemical gloves, masks or respirators, chemical boots, etc. As a result of wearing gas-tight protective clothing, the wearer will be in an isolated environment. Therefore, it is important to have the necessary communication equipment, mask anti-fog measures, cooling measures (e.g., ice undershirt), etc., and all related protective equipment should be considered, otherwise the wearer may be put in a dangerous situation.
Preparation
Protective clothing correctly wear pictures
Wearing before we must ensure that the applicability of chemical protective clothing, that is, whether the protective clothing is in good condition. Appearance check to see if there is no contamination on the exterior of the protective clothing, whether the seams are cracked, and whether there are any tears in the clothing. For airtight protective clothing, use a specialized airtightness tester to conduct regular airtightness testing (once every six months), so that the protective clothing can play a role in emergency wear. The inspection before wearing is very important. Serious injuries may result if the equipment is considered safe based on empirical judgment alone, when in fact it is not. Size correctly before wearing to reconfirm that the size of the protective clothing is the right size for you, too big or too small will cause inconvenience in the work process or accidentally hang bad, tear. Remove sharp objects to remove unnecessary keys, knives, pens, etc. from the body, so as not to cause damage to the protective clothing in the work.
Choose a place
The locker room is the ideal place to dress, if not also in a relatively uncontaminated environment. Under emergency rescue conditions, dressing should be done in a cold area.
Other necessary auxiliary systems Before using chemical protective clothing, make sure that other necessary auxiliary systems, such as air supply equipment and decontamination equipment, are in place.
Wearing
The wearing of protective clothing should follow a certain order, so as to ensure that the clothing is worn correctly and quickly, to play a role in the work of the protective clothing, but also for the use of a safe basis for taking off after use. Generally should follow the pants leg - boots - top - mask - hat -zipper - gloves in that order. Finally, to improve the airtightness of the entire system, tape can be added to openings (e.g., plackets, cuffs, pant leg openings, masks, and hooded interfaces of protective clothing. To enhance hand protection you can choose to wear two layers of gloves, etc. Throughout the process to try to prevent the inner layer of the suit from coming into contact with the external environment, so that the suit is not contaminated at the beginning.
Work
In the course of work, it is important to note that when chemical protective clothing is continuously contaminated by chemicals, it must be replaced within its specified protective time. If the chemical protective clothing is torn, it should be replaced immediately.
On gas-tight protective clothing or sealing very good non-gas-tight protective clothing, due to the work in a relatively isolated space, it is recommended to follow the principle of two companions, that is, at least two people together *** with the same access to the work area, in the unlikely event of a situation can be rescued in a timely manner.
Chemical protective clothing fabrics can provide hours of effective protection, but if you are wearing an air respirator, the working time is determined by the working time of the air respirator. It is important to pay attention to the effective working time of the air respirator, and to replace it in advance before the cylinder runs out. And when calculating the effective working time, the time taken up by walking and changing equipment should be taken into account.
Removal
Removal of protective clothing should be guided by the principle of removing protective clothing safely without contamination of the human body and the environment. Here to emphasize, very important, but often overlooked point is that before removing the chemical protective clothing to carry out the necessary washing decontamination. The decontamination referred to here is only for the purpose of being able to safely remove the suit without contaminating the wearer or the environment, and not for the reuse of certain suits. Depending on the contaminant, decontamination can be as simple as a bucket of water to get rid of general contaminants, or adding some detergent for rinsing. It is important to note that some chemicals, such as concentrated sulfuric acid, will react violently and exothermically when exposed to water, and this should be absorbed off the surface of the clothing before rinsing with water. This can avoid high heat damage to the protective clothing, and then cause pollution and harm to the wearer.
After washing the decontamination, taking off the chemical protective clothing also needs to follow a certain procedure, generally zipper - hat - top - sleeves -gloves - pants legs - boots - respirator. Before taking off the gloves should try to contact the outer surface of the protective clothing, after the gloves are taken off should try to contact the inner surface of the protective clothing, the protective clothing should be taken off with the inner surface facing outward, wrapping the outer surface and the contaminants inside, to avoid the contaminants from coming into contact with the human body and the environment. The removed protective gear should be centralized to avoid expanding the contamination in the process. It should be noted here that for protective clothing that is complicated and bulky to wear, such as gas-tight or liquid-tight protective clothing, putting on and taking off is recommended to be assisted by another helper, who can help the wearer to carry out some of the more difficult tasks such as adjustments and zippers, and ultimately to check the condition of the whole protective clothing once it is put on. When assisting with the removal of the suit, the assistant should also be properly protected from contaminants as they may come into contact with the suit.
