It is possible to replace the CO2 cylinder in an inflatable PFD each time the PFD is inflated.
<h3>What is an inflatable PFD?</h3>
An inflatable PFD is a specific inflator mechanical device based on a CO2 cylinder that fills a given sac with air.
Inflatable PFDs need to have to maintaining different types of safety measures to avoid the failure of the device (especially in emergency situations).
Inflatable PFDs can be classified according to their features into Type I, Type II, Type III, and Type V (for example, Type III allows to buoy to more than 15 pounds), where Type IV PFDs are not inflatable.
In conclusion, it is possible to replace the CO2 cylinder in an inflatable PFD each time the PFD is inflated.

The number of ways the skaters can finish the competition is 40,320 ways
The different ways 3 of the skaters finish first, second and third is 56 ways
Given the following
- Number of skaters featured = 8 skaters
If the skaters finish the competition, the number of different ways the skaters finish the competition is expressed as:
8! = 8*7*6*5*4*3*2
8! = 56*30*24
8! = 40,320.
The number of ways the skaters can finish the competition is 40,320 ways
If 3 of the skaters finish first, second and third, the number of ways this can be done is given as:
8C3 = 8!/(8-3)!3!
8C3 = 8!/5!3!
8C3 = 8*7*6*5!/5!3!
8C3 = 56 ways
Hence the different ways 3 of the skaters finish first, second and third is 56 ways
