Safety Boot Standards Uk

[Candi Ruman]

Thestandard EN ISO 20345 defines both the basic and additional requirements for safety shoes for commercial use. Footwear in accordance with EN ISO 20345 is intended to protect the wearer from bumps, crushing, falling or rolling objects, from walking into sharp or pointed objects, heat or cold, and hot substances.

Examples of aspects dealt with in the standard are handling mechanical risks, slip resistance, thermal risks and ergonomic properties. Additional standards relating to individual activities deal with risks in relation to footwear with electrical insulation, for example, and shoes to protect against chemicals, etc.

Safety footwear is divided into different protection classes depending on the requirements fulfilled. The safety footwear in protection class SB fulfil the minimum requirements in accordance with EN ISO 20345.

Safety is one of the most important aspects of being on a job site. However, regulations can be confusing and difficult to follow. That's why we came up with a simple, easy-to-read guide to help explain the ins and outs of safety footwear.

Before jumping into the safety standards themselves, it's important to understand who creates and enforces them. There are two groups to know about: ASTM International, which creates the regulations, and the Occupational Safety and Health Administration (OSHA), which requires workers and companies across the country to adhere to those regulations.

ASTM International (formerly the American Society for Testing and Materials) is an organization that develops standards for a range of services, systems, materials and products worldwide. Made up of well-qualified volunteers, ASTM International performs lab tests on safety footwear to determine what level of protection is considered safe (or unsafe) on the job. It's ASTM's labels that end up on the tongues of your boots, and ASTM's safety tests that decide which boots qualify for those labels.

There are two ASTM International documents that govern safety footwear: ASTM F2413 and ASTM F2412. The former outlines the level of protection that safety footwear features must provide for workers (and the labeling system used on boots and shoes themselves), and the latter is, essentially, a guideline for researchers and scientists that details the laboratory methods used in safety footwear testing.

If you've worked on a job site at all, "OSHA" and "workplace safety" should be practically synonymous. The Occupational Safety and Health Administration is a government agency that works to assure safe, healthy working conditions across a variety of industries. While OSHA implements and enforces safety rules for just about everything (including safety footwear), they don't just come up with those rules on their own; they seek advice from industry professionals like ASTM International to help create their guidelines.

Section 29 of OSHA's Code of Federal Regulations 1910.136 maintains that employees need to wear safety footwear "[W]hen working in areas where there is a danger of foot injuries due to falling or rolling objects, or objects piercing the sole, or when the use of protective footwear will protect the affected employee from an electrical hazard, such as a static-discharge or electric-shock hazard." Given the broad scope of those requirements, it's likely that you'll need footwear with safety features more often than not.

Many of these protective features offer a range of protection. Again, your employer should let you know what level of protection you'll need for your job site (though in many cases, they'll require you to have the most protective style available).

Safety toe boxes, typically made from steel, aluminum or composite materials and built into the toe section of a boot or shoe, provide protection to the toes from falling objects. The ASTM F2413 guidelines outline three levels of protection safety toes can provide: protection against 75 foot-pound impacts, 50 foot-pound impacts and 30 foot-pound impacts.

In layman's terms, a foot-pound is the amount of force (in pounds) an object exerts when dropped from the height of one foot. This means that a boot with a toe cap rated for 75 foot-pounds of protection will protect your toes from a 75-pound object dropped from a height of 1 foot (or a 150-pound object dropped from 6 inches, or a 37.5-pound object dropped from 2 feet, etc.). Most employers recommend wearing I/75 footwear.

Your toes aren't the only part of your foot that may need protection from falling objects; the metatarsal bones that run across the top of your feet are just as prime a target. Many pairs of safety footwear are made with a leather flap with metal or plastic inside called a met guard. These guards fold over the laces of the boots, protecting the metatarsal bones.

Just like safety toe boxes, met guards are rated for 75, 50 and 30 foot-pounds of protection, with most employers recommending Mt/75 met guard boots. The protection ratings are the same, too: Mt/75 boots offer protection from a 75-pound object falling from a height of 1 foot.

A safety toe box or a met guard simply can't protect your feet from a falling object that weighs over 1,000 pounds, even if that object were dropped from just a few inches. Compression, on the other hand, is much easier to protect against than impacts, and as a result, there exists footwear that offers protection against massively heavy objects rolling onto your feet.

Some work sites lend themselves to potentially dangerous electric shocks. Live circuits, electrically energized conductors and other parts are extremely hazardous. Luckily, there are electrical hazard-resistant pairs of footwear that insulate against accidental electrocution. To qualify for an ASTM rating, this footwear must provide protection against open circuits up to 600 volts in dry conditions. For reference, a typical wall outlet puts out 120 volts; protection against 600 volts is more than enough in most settings.

There have been many instances of accidental fires and explosions caused by static discharge. Static electricity builds up naturally in a person's body, flammable or explosive fumes and vapors accumulate around them, and an accidental static discharge acts as the match that sets everything ablaze. Static dissipative footwear conducts static electricity to the (grounded) floor to prevent these sorts of accidents.

Similar to impact resistance, metatarsal protection and compression resistance, static dissipative footwear comes in three protective ranges: SD 100, SD 35 and SD 10, whose soles offer resistance levels up to 100 megaohms, 35 megaohms and 10 megaohms, respectively. The higher the resistance level, the easier it is for static electricity to dissipate into the floor.

The thick, rubber outsole of a boot or shoe provides ample puncture protection from materials like sharp plastic or glass. Sharper objects like scrap metal, screws, nails and other hazards, on the other hand, can cut through regular boot soles with ease. Puncture-resistant footwear ensures protections against these kinds of materials by way of a non-removable metal plate placed between the insole and outsole of the footwear. These metal plates, though heavy, are rigid and strong enough to prevent accidental punctures in the majority of cases.

While electrical hazard-resistant footwear provides adequate protection for most workers on most job sites, dielectrically insulated (DI) footwear goes the extra mile. These large, all-rubber overshoes provide additional protection against much larger electrical hazards, like power lines. Their use is uncommon and generally reserved for specific needs in specialized industries; typically, you won't need this level of electrical protection on the job.

Chainsaws are normally used around chest height, safely distanced from the feet of their users. Still, some chainsaw-heavy jobs may require boots with chainsaw protection (CS) to keep your feet safe from the quickly rotating blades. Like dielectrically insulated boots, footwear with chainsaw protection is uncommon and very industry-specific. Your employer will be sure to let you know if you need them.

ASTM International quite literally produces thousands of safety labels for thousands of hazards across dozens of needs, products and industries. Because of that, the labeling standards can become confusing and difficult to understand. We'd like to clear up some common points of confusion about safety footwear and their labels and standards.

Firstly, it's important to know that ASTM safety labels weren't always the only ones workers had to know about. For quite a while, footwear used safety labels from another professional industry group, the American National Standards Institute (ANSI). At one point, OSHA's Code of Federal Regulations cited both ASTM International's F2413 and ANSI's Z41-1999 guidelines for their safety footwear standards. The two sets of rules were essentially the same, though, so on March 1st, 2005, OSHA removed all references to ANSI's Z41-1999 and has cited only ASTM's F2413 since.

As mentioned above, ASTM maintains two documents regarding workplace safety footwear: F2413 and F2412. The first document, F2413, describes the levels of protection provided by safety footwear and the labeling system used on the footwear itself. The second document, F2412, outlines the testing parameters for scientists and researchers to use to determine whether or not a certain pair of footwear qualifies for certain safety standards (impact resistance, static dissipation, compression resistance, etc.).

Manufacturers are often eager to provide as much documentation as possible to demonstrate that their footwear is up to safety codes. As a result, you may see some boots or shoes labeled as meeting "ASTM F2412 and ASTM F2413 standards." To avoid confusion, you can disregard the ASTM F2412 labels; as a worker, you only need to ensure your footwear is on par with ASTM F2413.

ASTM International's standards aren't necessarily written in stone; in fact, there have been many updates to their contents through the years. In a lot of cases, labeling systems reference those years. For instance, you may see ASTM F2413-05 (i.e. the 2005 edition of the standards), ASTM F2413-11 (i.e. the 2011 edition of the standards), ASTM F2413-18 (i.e. the 2018 edition of the standards), etc. For all intents and purposes, these year markers can be ignored; the core standards for labeling and protection thresholds on safety footwear have not changed.
