What does this mean?
SB (Safety Basic)
The basic standard for safety footwear. These have steel toe protection against a 200-joule impact. They may also have additional safety features which will be shown via other symbols. For example, if you see SB-P this means that the safety footwear also has the additional feature of Penetration Resistance of the Midsole.
S1
Whilst including the basic protection found in the SB classification, S1 also ensures the footwear has antistatic protection, is resistant to fuel oil and has energy absorption in the heel. Again other symbols can be added, such as S1-P as above.
S2
S2 offers all the same protection as S1, but also includes the added protection of preventing water penetration and absorption of the upper.
S3
S3 safety footwear also offers all the same levels of protection as S2, plus a midsole for penetration resistance.
In many workplaces, slip resistant footwear is required. Below are the separate standards of slip resistance:
