A steel-toe boot (also referred to as a security boot, steel-capped boot, metal toecaps or security shoe) is a sturdy boot or shoe that has a protecting reinforcement within the toe which protects the foot from falling objects or compression.

Though historically manufactured from metal, the reinforcement can be manufactured from a composite materials, a plastic resembling thermoplastic polyurethane (TPU) and even aluminum. Metal-toe boots are necessary in development and manufacturing, in addition to a wide range of different industries. Occupational security and well being laws or insurance coverage necessities could require using such boots in some settings, and will mandate certification of such boots and the show of such certification straight on the boots. The markings on the boot label will point out the nationwide or worldwide requirements that the boot was supposed to fulfill, and determine the extent of safety supplied for impression, compression, penetration, and electrical shock. Security sneakers are efficient in preserving the toes of commercial staff secure from sharp and heavy objects whereas working in factories. Footwear to be used in chemical processing or semiconductor manufacturing can also be rated to dissipate static electrical energy.

Security footwear now is available in many types, together with sneakers, clogs, and gown sneakers. Some are fairly formal, for supervising engineers who should go to websites the place protecting footwear is necessary.

Some manufacturers of steel-toe footwear have turn into modern inside subcultures resembling skinhead, punk, and rivethead. Whereas manufacturers that have been beforehand famend inside the trend business have additionally diversified into the protection footwear market, industrial manufacturers like Caterpillar, Rock Fall and JCB have additionally issued licenses to provide security footwear.

Security standards[edit]

United States[edit]

A pair of ASTM 2412-2413 compliant S3 security sneakers

In the US, the most typical requirements utilized by employers for protecting footwear are ASTM Worldwide requirements F2412-18a (Normal Take a look at Strategies for Foot Safety) and ASTM F2413-18 (Normal Specification for Efficiency Necessities for Foot Safety).

OSHA beforehand required compliance of ANSI Z41.1-1991, “American Nationwide Normal for Private Safety-Protecting Footwear,” if bought after July 5, 1994,[1] or ANSI normal “USA Normal for Males’s Security-Toe Footwear,” Z41.1-1967,[2] if bought earlier than that date.

As of March 1, 2005, ANSI Z41 has been changed by ASTM F2412 and ASTM F2413[3]

ASTM licensed footwear should embrace a label that signifies which security requirements that individual footwear meets. The varied security requirements embrace:

  • I – Affect
  • C – Compression
  • Mt – Metatarsal
  • Cd – Conductive
  • EH – Electrical Hazard
  • SD – Static Dissipating
  • PR – Puncture Resistant

Canada[edit]

(CSA) inexperienced triangle and orange electrical security tags

In Canada, the most typical requirements utilized by employers are these of the CSA Group (previously the Canadian Requirements Affiliation; CSA), printed in CSA normal Z195. These requirements are just like the ASTM Worldwide requirements generally utilized in the US however the testing strategies do differ.

CSA requirements on shoe labels function distinct shapes and colours, represents particular security standards for all security footwear and attire:

  • Inexperienced triangle with CSA image – Sole puncture safety with a Grade 1 protecting toe. (Heavy work atmosphere: development; machine retailers; the place sharp objects are current)
  • Yellow triangle with registered image – Sole puncture safety with a Grade 2 protecting toe. (Gentle industrial work environments)
  • White rectangle with orange Greek letter omega and CSA image – Soles that present electrical shock resistance, with Ω (capital omega) being the image for ohms {of electrical} resistance. (Any industrial atmosphere the place dwell electrical conductors can happen)
  • Yellow rectangle with inexperienced letters “SD”, a grounding image and CSA image – Able to dissipating an electrostatic cost in a managed method. (Any industrial atmosphere the place a static discharge generally is a hazard for staff or gear)
  • Purple rectangle with a black letter C, grounding image and CSA image – Soles which can be electrically conductive. (Any industrial atmosphere the place low-power electrical costs generally is a hazard for staff or gear)
  • White label with inexperienced fir tree image and CSA image – Gives safety when utilizing chainsaws. (Forestry staff and others required to make use of a chainsaw)
  • Blue Sq. with CSA image – Grade 1 protecting toe solely. (For all different environments not listed above)

Usually, a security shoe is a shoe that follows at the least one in every of 5 standards. The standards {that a} security shoe adheres to could be discovered by on the lookout for the CSA (Canadian Requirements Affiliation) alphanumeric code discovered contained in the shoe. This code is made up of a mix of 5 completely different symbols:

  • 1, 2 or 0;
  • P or 0;
  • M or 0;
  • E, S or C;
  • X or 0.
  1. The primary code signifies whether or not the shoe has a steel-toe cap (a metallic shell embedded on high of the toes a part of the shoe). “0” means there may be none. “1” means that there’s, and it resists an impression of 125 joules (22.7 kg object falling from 56 cm above). “2” signifies that it resists an impression of 90 joules.
  2. The second code signifies whether or not the shoe has soles that shield the arches of the toes from punctures. “P” means it does. “O” means it does not.
  3. The third code signifies whether or not the shoe has a metatarsus safety towards shocks and collisions. “M” means it does. “O” does not.
  4. The fourth code signifies the shoe’s electrical properties. “E” means it resists electrical shocks. “S” means it disperses static electrical. “C” means it conducts electrical energy.
  5. This final code is discovered solely on sneakers that shield the foot from chainsaws, i.e. chainsaw boots. “X” it does, “O” doesn’t.

Europe[edit]

The Worldwide Group for Standardization offers the European normal for security footwear. The present one is ISO 20345:2011 – beforehand ISO 20345:2004.

The codes relevant to European security footwear are:

Protected Space Kind of Safety Code

Use as a weapon[edit]

Metal-toe boots have been utilized in assaults, such because the assault on Josie Lou Ratley, a Florida teenager.[5] Nightclubs and different leisure venues ceaselessly embrace a “no metal toecaps” rule as a part of their gown code to mitigate the potential of critical damage to different patrons if the wearer turns into violent.[citation needed] Use of bovver boots in soccer hooliganism was countered by warnings to followers that they must take away such boots to be able to attend soccer matches.[6]
