You may have noticed that safety footwear is marked with the EN345 or EN ISO 20345:2004. To assist in you buying the right specification safety footwear other markings are applied. The markings are commonly found on the tongue or stitched/printed into the inside of the upper.
Standard safety boots and shoes – the most common markings
SB – The SB marking defines the minimum standard of having a 200 joule safety toecap
S1 – Adds anti-static properties and a shock absorption system in the heel area of the footwear
S2 – As SB and S1 with the addition of a water resistant treated upper (please note: not necessarily waterproof)
S3 – As SB/S1/S2 with the addition of a midsole for underfoot protection
S1P – just to confuse slightly S1P adds underfoot protection to SB/S1 specification
SBP – and SBP adds underfoot protection to SB specification
So you can see from above that an S3 specification boot or shoe has all the main ingredients to make it suitable for a wide variety of tasks. Many of the styles within the Howsafe range are S3 specification.
Other markings of note are
HRO – heat resistant out soles are commonly made of rubber/nitrile and are rated to 300 degree centigrade which makes then suitable for use in many environments such as general engineering where hot swarf may be present. Most types of foundry require HRO’s to be used in conjunction with safety footwear that features a quick release mechanism.
SRA – Anti slip test using a cermic tile and detergent
SRB – Anti slip test using a steel plate with oil
SRC – if safety footwear passes both the SRA and SRB anti slip tests it qualifies for the SRC highest anti slip rating.
For footwear made up of rubber or polyurethane such as wellingtons have their own “S” ratings.
SB – feature a 200 joule toecap
S4 – SB with the addition of energy absorbing heal and anti static properties
S5 – as S4 plus underfoot protection
Beyond that there are other EN markings – EN346 is used for footwear that has a lower protection of 100 joules on the toecap and although is rare these days can be found on some office styles.
EN347 – Styles with EN347 are NOT required to have a safety toecap – these “occupational styles” are commonly used for professional use within the workplace such as health care where a safety toe is not deemed necessary.
Going even further, rescue services, chemical industries, electricians, electrical discharge for hi-tech industries and chainsaw (to name a few special categories) users all have footwear that is made specifically for the intended purpose. Howsafe will work closely with you in conjunction with the footwear manufacturer to make sure you have the right footwear on your feet.
