Safe use of protective clothing preparatory stage
We must ensure that before wearing chemical protective clothing applicability , ie protective clothing is in perfect condition .
Visual inspection to see there is no appearance of protective clothing contaminated sutures is cracking , there is no break clothes . For airtight protective clothing , the use of specialized leak detector leak detection regularly ( every six months ) , so that in an emergency , when wearing protective clothing can play a role. Check before wearing is very important. If you only experience judgment, that the equipment is safe , but in fact unsafe circumstances, it may cause serious injury.
Size properly wearing protective clothing before re- confirm the size is suited to their size , too big or too small will cause the work process intended to plug mobility or bad tear.
Remove sharp objects to remove unnecessary keys , knives, pens, etc. taken down from the body , so protective clothing at work causing damage .
Select the locker room is the ideal place to dress place , if not also in relatively unpolluted environment. Under the conditions of the emergency rescue , dressed in cold areas should be .
Other necessary auxiliary systems in the use of chemical protective clothing , should ensure that such gas equipment, decontamination equipment and other necessary auxiliary systems ready.
Safe use of protective clothing worn stage
Wearing protective clothing to follow a certain order , so you can ensure the correct wearing personal protective clothing , fast, play in the work effectiveness of protective clothing , but also for take off safely after use basis . General should follow the trouser legs - boots - Tops - Masks - Hats - zip - gloves order. Finally, in order to improve overall system tightness can be in the openings ( eg placket , cuffs , pants mouth , face masks and protective clothing hooded interfaces tape affixed in order to strengthen the hand can choose to wear two layers of protective gloves , etc. In throughout the process to try to prevent contact with the inner layer of protective clothing to the external environment and protective clothing to prevent contamination at the outset .
Protective clothing for use at work
In the course of the work , pay attention to chemical protective clothing contaminated by chemical substances continue to be protective in its provisions within the time change . If breakage chemical protective clothing should be immediately replaced.
Protective clothing for tightness or non-hermetic sealing good protective clothing , because in a relatively isolated space , it is recommended to follow the two concomitant principle that at least two people together into the work area to prepare in Wan a situation occurs when a timely rescue .
Chemical protective clothing fabrics can provide hours of effective protection , but if the wear respirators when working time working hours by air respirator decision. Pay attention to the effective use of SCBA time runs out to advance the cylinder replacement. And in the calculation of effective working time should be considered when the share of walking and replacement of equipment time .
The correct protective clothing to wear off order
Take off protective clothing should follow the principle is to safely take off protective clothing, not humans and the environment caused by pollution. It should be emphasized , it is important, but often overlooked point is that the chemical protective clothing off before the necessary decontamination decontamination . Decontamination decontamination herein only in order to safely take off protective clothing to make the wearer or to the environment without pollution , and not to re- use some of the protective clothing . According to different contaminants , decontamination can be very simple , such as a bucket of water to get rid of pollutants in general , or add some detergent to wash . This time to pay attention to some chemicals, such as concentrated sulfuric acid with water violent exothermic reaction occurs , this time should be first chemicals siphoning off the surface of the clothes , and then rinse with water. This prevents heat damage to protective clothing , which in turn cause pollution and harm to the wearer .
After decontamination decontamination , chemical protective clothing also need to take off to follow certain procedures , usually zip - hat - shirt - sleeves - gloves - legs - boots - respirator. Take off the gloves in front to try to contact with the outer surface of protective clothing , gloves off after going to try to contact with the inner surface of protective clothing , protective clothing should be off after the inner surface outwards, the outer surface and pollutants wrapped inside to avoid contaminants to the human body and the environment. Take off the protective equipment should focus on , to avoid contamination during this process to expand .
To note here is that, for liquid tightness tightness or wear protective clothing such as more complex, bulky protective clothing, wear , and have suggested that there is another one off the auxiliary aides can help the wearer to make some adjustments and zippers and other more hard work and final inspection of the entire protective clothing to wear after the situation. When the auxiliary take off protective clothing , due to possible exposure to contaminants , the assistant must be properly protected against contamination.
The necessary training and exercises to help play better protective clothing protective effect
Every one needs to wear chemical protective clothing personnel must be trained in advance , which could come by the provider of protective clothing can also be carried out by experienced staff to carry out. Here in addition to the previously talked about all things, it should be emphasized that there remain tight wearing protective clothing ( zipper pull good openings and convergence with other protective equipment and good ) for the importance of safety , because for every day wear protective clothing workers this may not be very comfortable, but for the entire chemical protective system to play the best results, ensure safety is crucial, this time protection is still the first place , when necessary, need to reconsider comfort.
For emergency rescue , in addition to also pay the necessary training exercises . Enables the wearer to become familiar with a variety of wearing protective equipment and performance, and to become familiar with the wearing protective clothing, protective clothing , especially airtight case , can well meet and exchange and companions .
As training and exercises of chemical protective clothing is damage , may result in failure of hermetic protective clothing , protective clothing and airtightness is very expensive , and some manufacturers ( eg DuPont ) can provide the same material , the same design specialized training suits, the price is relatively cheap. You can also use expired or protective clothing for the exercise , but the premise is protective clothing can not have harmful pollutants toxic to humans .
Protective clothing, use of effects monitoring
Finally, mention is that the use of chemical protective clothing in the process to be carried out for all users of occupational health surveillance . Such as the use of personnel in the use of skin itching , tingling and other hazards symptoms should discontinue use and re-evaluate the suitability of the selected chemical protective clothing . Proper use of chemical protective clothing is a very practical topic, in practice , there are many details that need attention , through the development of procedures and continuous improvement in practice , to make the use of chemical protective clothing standards, to achieve the desired protective effect .
