Your safety footwear is safe, comfortable and performing thanks to the work of thousands of people who, since the beginning of the history of safety footwear, have continued developing ideas for making it better. Let’s discover in this article the most important norms, standards and markings for safety footwear!

Other than just improving it under a technical point of view, many people have worked to create a series of norms and standards to have the footwear certified and uniformed in all its technical and construction aspects.

The norms are under continuous development, the greater is the experience on materials and types of risks in the work place, the stricter the norms get and the safer the footwear that you will wear at work become.

My goal in this article is to give a short and useful list of the most important norms, standards and markings for safety footwear.

Of course I cannot list the totality of norms and aspects, but I’d like to show you the most important ones and to describe them in general. I’m sure that it will help you to choose the right safety footwear for your needs.

  • You have to buy your safety footwear but you don’t know what norms it has to follow?
  • You are not sure, but curious to know about the different norms/standards for safety footwear?

I will now list you the different norms and markings for choosing the right safety footwear for your needs

List of the most important norms, standards and markings for safety footwear

  • ASTM F2413-11 = ASTM means “American Society for Testing and Materials”. The standard  2413 sets the minimum required standards and testing procedures for certifying safety footwear. 11 is the year of the standard, in this case 2011.
  • CSA Z195-14 = it is the seventh edition of CSA Standard Z195, covering design and performance requirements for protective footwear, toe protection, puncture protection, metatarsal protection, electric-shock resistance, slip resistance, and other requirements
  • I/75 = Impact safety-toe protection. This is the requirement for the impact resistance of the toe cap protection.
  • C/75Compression safety-toe protection. This is the requirement for the compression resistance of the toe cap protection.

How is the I/C75 conducted? The test is performed by dropping a 50 pound weight from a pre-determined height of 1.5 feet at a designated speed. It corresponds to an impact of up to 75 feet-pounds and a compressive load of 2,500 pounds. When receiving the impact, the toe cap has to show a clearance (under the safety toe) of: Men 0.500 Inches (equivalent to 12.7mm), Women 0.468 Inches (equivalent to 11.9mm)

  • PR = “Puncture resistance”. Puncture resistant footwear includes an anti perforation plate usually placed below the insole or inside the outsole compound which reduces the possibility of punctures from external objects to the bottom of the feet. PR footwear should resist to a minimum nail penetration force of 270 pounds.
  • EH = Electrical shock resistance. EH means “Electrical Hazard” protective footwear. It is designed to reduce the hazards due to an accidental contact with live electrical circuits, it can be used as a secondary protection for electrical hazard environments, mostly with carpets and other types of protections. EH footwear must withstand the application of 18,000 volts at 60 Hz for 1 minute, with a maximum current leakage of 1.0 milliampere.
  • SD = “Static dissipative” property. SD footwear is designed to reduce the excess of static electricity by conducting it to the ground, protecting at the same time the wearer from electrical hazards due to live electrical circuits. The electrical resistance must be over 1,000,000 ohms (1 MOhm) and below 100,000,000 ohms (100 MOhms).
  • CD = Conductivity resistance. Conductive footwear is designed to dissipate electrostatic charges from a worker’s body through the shoes to the ground. The scope is to minimize static electricity and take the electrostatic charge out of your body so that electrostatic sparks do not happen. The range of the electrical resistance of the conductive safety footwear should between 0 and 500,000 ohms. (0,5 MegaOhm)
  • MT/75 = Metatarsal protection. It is designed to prevent or reduce injuries when the toe and metatarsal areas of the foot are exposed to hazards.

The metatarsal test is performed by dropping a 50 pound bar 1.5 feet onto the metatarsal protection (equivalent to 75 feet pounds of impact energy). The energy is the same as for the toe cap impact test. The clearance under the metatarsal protection after the impact are Men 1 Inch (equivalent to 25.4mm), Women 0.937 Inch (equivalent to 24mm).

Robert Frog
I was born in London in 1975 and still live here. I could define myself, summing up in a few words my long working career, a great expert in the field of foot and foot problems. Immediately after graduating in Motor Science I started working in an orthopaedics in which orthotics were made to measure for people with foot problems. In 1999 I was hired as Key Account Manager in a well-known chain of safety footwear and other personal protective equipment. Among my clients I had several industries, which I visited regularly to understand the needs of workers, both in terms of protection and comfort. During these years I have consolidated my knowledge on foot problems. Furthermore, I studied carefully the products I proposed: attending courses, participating in trade fairs and, often, accepting the invitation of manufacturers to visit the factories. I was thus able to observe closely the techniques and materials used to produce the best safety shoes. Since 2015 I have been collaborating with the PPE Academy for the content of Safety Shoes Today.
