"Guidance for the selection, use and maintenance of safety and occupational footwear and other personal protective equipment offering foot and leg protection"

ISO/TR 18690:2012 provides guidance for the selection, use and maintenance of personal protective equipment and safety and occupational footwear. It is intended for footwear manufacturers and suppliers, employers and self-employed people, safety engineers and other users. ISO/TR 18690:2012 also provides guidance for preparing national guidance in this area.

"Respiratory protective devices — Human factors — Part 3: Physiological responses and limitations of oxygen and limitations of carbon dioxide in the breathing environment"

This Technical Specification gives:

1) a description of the factors contributing to the present content of the Earth's atmosphere;

2) a description of the physiology of human respiration;

3) a survey of the current biomedical literature on the effects of carbon dioxide and oxygen on human physiology;

4) examples of environmental circumstances where the partial pressure of oxygen or carbon dioxide can vary from that found at sea level.

This Technical Specification identifies oxygen and carbon dioxide concentration limit values and the length of time within which they would not be expected to impose physiological distress. To adequately illustrate the effects on human physiology, this Technical Specification addresses both high altitude exposures where low partial pressures are encountered and underwater diving, which involves conditions with high partial pressures. The use of respirators and various work rates during which RPD can be worn are also included.

"Acoustics -- Hearing protectors -- Part 5: Method for estimation of noise reduction using fitting by inexperienced test subjects"

ISO/TS 4869-5:2006 specifies a method for measuring noise reduction of passive hearing protectors at the threshold of hearing. The method is designed to provide estimates of the noise reduction obtained by typical groups of users in real-world occupational settings, who may lack the training and motivation to wear hearing protectors in an optimum manner. The principle of the test method is to measure the difference in hearing threshold with and without wearing a hearing protector. This difference between the thresholds constitutes the noise reduction. The measurement is done twice on a given number of test subjects. This test method yields data that are collected at low sound pressure levels (close to the threshold of hearing), but which are also representative of the noise reduction values of hearing protectors at higher sound pressure levels. ISO/TS 4869-5:2006 is inapplicable for level-dependent hearing protectors for sound pressure levels above the point at which their level-dependent characteristics become effective.

"Coveralls, Toxicological Agents Protective, M-3"

This document covers a one piece coverall for the protection of personnel engaged in extremely hazardous decontamination work or other special operations involving danger from spillage or splashing of liquid chemical item.

"Cover, nuclear, biological, and chemical protective (NBC-CP)"

This specification covers a lightweight disposable (low cost) cover to protect exposed supplies and equipment from nuclear/chemical/biological attack and serves to ease the burden of decontamination throughout the Army.
