A gas mask is a necessary thing in the field. And at home (God forbid, of course) there can be a fire. In order not to suffocate, you will have to put on a gas mask and run out of the room. The whole problem is not how to put on a gas mask, but how to put it on quickly. We will not be able to teach you the words of practice, but the theory is worth telling.
Instructions
Step 1
To know which gas mask will fit you, you need to know some parameters, namely, the horizontal and vertical head circumference. The horizontal girth is measured along a closed line that runs from the front along the brow ridges, from the side just above (2-3 cm) of the auricle and from the back along the most protruding part of the head. And vertical girth can be determined by measuring the length of the vertical line passing through the chin, cheeks and crown of the head. The obtained measurements should be rounded so that the last digit is 0 or 5.
Step 2
Now add both results and see what size of gas mask you need: - Less than 1190 mm - the first size;
- From 1190 to 1210 mm - the second size;
- From 1215 to 1235 mm - the third size;
- From 1240 to 1260 mm - the fourth size;
- From 1265 to 1285 mm - the fifth size;
- From 1290 to 1310 mm - the sixth size.
Step 3
And now about how to put on a gas mask correctly: you need to stick your head into this saving "rubber bag with a filter" either after the "Chemical alarm" signal at the command of "Gaza", or on your own initiative.
Step 4
First, close your eyes tightly so that they are not corroded by caustic smoke (you never know what happened there), then remove the hat, remove the gas mask from the special bag and grab the helmet-mask by its lower part so that the thumbs are outside, and the rest were inside.
Step 5
Next, you need to put the bottom of the helmet-mask under the chin and pull it over your head with a sharp upward movement of your hands. You will need to practice so that no wrinkles remain after pulling on the gas mask. Now you can take a full breath, open your eyes and resume breathing.
Step 6
Considering that the operations described above, you will have to carry out blindly, you need to train for a long time. Although it all depends on the person and his degree of learning. With a lot of practice, you can even come close to the army regulations for wearing a gas mask: about 7-10 seconds.
