Do you know the difference between safety classes in protective footwear?

There are a few simple rules for choosing between SB, S1, S1P, S2 and S3 safety footwear:

• Do you work indoors, with no risk of water penetration, and need toe protection and good breathability?
  Then you need SB or S1 safety footwear.

• Do you work indoors, with no risk of water penetration, and need toe protection, but also need protection against perforation and good breathability?
  Then you need S1P safety footwear.

• Do you work outdoors and need toe protection and protection against water penetration?
  Then you need S2 safety footwear.

• Do you work outdoors and need toe protection, protection against perforation and protection against water penetration?
  Then you need S3 safety footwear.

As you can see, the biggest difference between SB, S1, S1P, S2 and S3 safety footwear lies in resistance to water penetration and in the puncture-resistant plate in the sole.
S1P and S3 are essentially S1 and S2 safety footwear with an additional puncture-resistant plate in the sole.
