Design of safety shoes for women
Gestaltung von Sicherheitsschuhwerk für Frauen [en alemán]
Studies of the differences between men's and women's feet were performed to establish whether safety shoes designed for men could also be used by women. After the basic principles of shoe construction, the booklet deals above all with the anatomy of the foot, the demands to be made of a safety shoe, and foot form. Foot types and data to serve as a basis for lasts for a women's safety shoe were derived from measurements made in 682 women in North and South Germany and Mediterranean countries. Finally, practical hints are given relating to the different foot and lower leg dimensions found in women.

Safety footwear
Sicherheitsschuhwerk [en alemán]
This standard lays down safety specifications based on the 1968 Act respecting technical equipment in industry. Part 1 is devoted to safety toecaps (materials, dimensions and forms for men's and women's shoes, impact resistance of toecap), soles and heels. Details of tests performed on toecaps (impact test for indentation, dielectric strength, impact resistance) and soles. Part 3 lays down specifications for safety footwear for the building industry and work in quarries. Part 4 concerns footwear for use in the mining sector. In addition to the specifications set out in Part 1, Parts 3 and 4 specify reinforced penetration-resistant soles and ankle guards.

Methods for study of the efficacy of personal protective equipment against vibration - Part 1. Measurement of the efficacy of protective equipment at fixed workposts
Metody badania skuteczności antywibracyjnych ochron osobistych - Część 1: Metoda badań skuteczności zabezpieczeń przed wibracją na stacjonarnych stanowiskach pracy [en polonés]
Some brief considerations on transmission of vibration to the human body are followed by a description of the method developed to determine the efficacy of protective devices for the lower limbs exposed to vibration. The method is based on measurement of the transmittance at the median malleolus of the tibia, and uses a specially designed test bench. Description of the conditions ensuring reproducibility of the results, and conclusions of the study on the influence of conventional leather and microporous rubber footwear, and of certain factors reducing the elastoplasticity of the foot, on vibration transmission. Reduction of transmittance at the malleolus, expressed in dB, may be considered as the measure of vibration damping.

Safety footwear in flameproof areas.
Certain properties of the sole of footwear can have serious safety implications when static electricity is considered in explosive atmospheres. It is essential that safety shoes issued to personnel employed in such atmospheres should not be capable of building up electrostatic charges likely to cause a spark. This calls for conductive footwear and flooring. Mention is made of a special code of practice developed by Glaxo Laboratories in this connection. Specifications are given for electrically conducting and anti-static footwear (resistance not to exceed 10⁷ohms); the means of achieving and testing these properties are outlined. A personal conductivity tester is described.

CIS 76-211 Specification for lined industrial rubber boots.
This standard, which is based largely on ISO standard 2023, makes specifications for rubber ankle boots and rubber boots of half-knee, short-knee and knee height for men and women, and men's rubber boots of three-quarter length and full-thigh height, for use in industry. All the boots are intended for heavy duty, but attention is particularly drawn to BS 1870 which deals with safety boots of similar construction. Definitions are followed by sections on: minimum heights and thicknesses; fabrics; reinforcements; physical properties of soling and heel; performance requiremnts; marking; and testing. Specifications concerning minimum fabric strength, requirements for outsole and heel regarding tensile strength and elongation at break, flexing test limits etc. are given in tabular form.

CIS 75-2004 Knee pads for workers
Les genouillères pour travailleurs. [en francés]
Workers in the construction industry and civil engineering and miners are particularly prone to hygroma of the knee. The only means of prevention consists in the wearing of knee pads. After a brief description of this protective equipment, this article reports on trials of 11 types of knee pads (hardness, pressure on the knee) available commercially in France. The results are represented in graphs.

Safety shoes - An ergonomic approach
Chaussures de sécurité - Approche ergonomique. [en francés]
In France, shoes in general and safety shoes in particular are not sufficiently adapted to the individual characteristics of the feet (respective sizes of the toes, fallen arches, variations in foot width for a given shoe size). Detailed review of these points and statistical data on their distribution. In view of the complexity of the problems involved in safety shoes, the setting up of ergonomic groups is necessary both at the factory and at the design stage.

CIS 75-498 Shoe sole slipperiness standard status.
Describes the work of a committee of the American Society for Testing and Materials to prepare a standard for a test method for determining the slipperiness of shoe soles. The following factors are discussed: structure of the shoe; performance of foot inside shoe; platform shoes; behaviour of soling materials in presence of dust, water, oil, etc.; sole finish; age of material; ambient temperature. Shoe sole recommendations for various floor surfacings (ceramic tile, synthetic, concrete, wood, etc.) and conditions (wet, dry, greasy) adapted from research findings of the French National Research and Safety Institute (INRS), are given in tabular form. A slipmeter developed by a US insurance company is illustrated and described.

Safety footwear
Sicherheitsschuhwerk [en alemán]
Occupational accident statistics, particularly those concerning undergound workers in collieries, give indications (reproduced in the article) concerning the nature and causes of foot injuries, which are sustained principally at the level of the metatarsus. The author draws conclusions for the improvement of safety footwear: protection of the metatarsus and toes, guidance for the instep, nonslip soles. Reference to applicable German standards.
