[Physiologic and hygienic principles underlying creation of clothes protecting against cold].

The article presents principles underlying creation of clothes protecting against cold, in accordance with specific usage conditions (ambient air temperature and speed, ergonomic traits and metabolic level of work, duration of cold exposure). The authors listed requirements to thermal protection of clothes and to separate entities (hat, gloves, shoes) in relation to various climate regions. Major steps of creation and evaluation of the clothes are demonstrated.

[Method evaluating heat isolation for individual device suit designed to protect workers from coldness].

Based on results of personal research and of foreign studies, the authors present a method to calculate heat isolation for individual protective means set necessary for human heat state preservation in real working conditions. The method includes surface temperature measurements with consideration of cooling degree and energy consumption, calculation of separate elements of heat balance and density of "net" heat flow in correlation with cooling duration. Calculating heat isolation, the authors considered influence of wind speed on its value and air-resistance of outer clothing.

[Physiological-occupational requirements with reference to clothes protecting workers from low temperature and methods for the evaluation of heat insulation].

The authors specified a method regulating clothes production in accordance with physiologic and hygienic requirements that result from particular utilization conditions (ambient temperature, motion speed, energy expenditure, duration of exposure to cold). The article represents criteria for allowable heat state of human, requirements to heat insulation of clothes set and items (hat, mittens, and shoes) for various climate areas, for allowable duration of exposure to cold.

[Cold stress and its prophylaxis].

The authors present criteria of cold stress and their relationships with thermoregulatory strain, ability to work and some health state parameters. Findings are unfavorable influence of human cooling and adaptation to cold on vibration disease development. The article covers requirements to heat-proof properties of clothing set, to duration of exposure to cold in various climate areas of Russian Federation.

[The evaluation of skin temperature points and heat flow in the area of the foot for the measurement of the footwear heat insulation].

Analyzing results of the personal experiments, the authors present methodology to minimize number of sites for measurement of foot skin temperature and heat flow. Average foot temperature could be reliably measured through one or several sites. The studies revealed informativeness of each among 11 measurement sites and helped to specify corresponding equations for evaluation of foot heat conditions and heat insulation.

[Comparative evaluation of methods accepted by Russian and international standards to assess total resistance of special cold-proof clothing set].

Experimental studies helped to compare methods determining and calculating total heat resistance of clothing sets accepted by Russian and international standards. Findings are that difference in the total heat resistance values calculated on humans and on dummies in relatively still air and quiet conditions is caused by measurement technique applied. Significant difference in the total heat resistance values calculated in windy conditions or during walk require further research aimed to study influence of those factors on clothes' heat resistance.

[Physiologic and hygienic requirements for clothes protecting from cold during outdoors work in Northern regions].

The article presents main requirements met by clothing for protection against cold. The authors demonstrate calculation of desirable heat resistance of clothing and its components, results of experimental and occupational studies participated by humans and aimed at evaluation of individual protective means. The article shows role of individual protective means in maintaining desirable state of the workers.

[Revising sanitary norms of microclimate in industrial accommodations].

The article outlines new edition of a project "Sanitary norms of microclimate in industrial compartments". Up-to-date scientific data, results of studies concerning human heat state in experimental and industrial conditions, evaluation of the workers' health state helped to modify optimal and allowable parameters of microclimate, to rectify requirements for measurement conditions and measuring devices. When the recommended temperature could not be maintained, the duration of work in such conditions should be limited for prevention of overheating and overcooling. To examine prophylactic measures against overheating, the authors suggested an integral characteristic of heating environmental load (TNS-index) and set its safe values.

[Substantiation of physiologic and hygienic requirements of heat-proof properties of winter headgear].

Experimental studies conducted in cooling environment assessed the features of heat exchange and thermoregulation of head during physical work varying in hardness and type. The studies determined allowable parameters of heat exchange on head (skin temperature and surface heat outflow), which are necessary for construction and evaluation of headgear. The article presents correlations between main heat-proof parameters of headgear (total heat resistance, thickness of materials and their permeability to air). The data of experimental and industrial trials helped to elaborate physiologic and hygienic requirements for heat-proof headgear in various climate conditions.

[Grounds of the duration of work shift for female vegetable growers working in the field in the summer].

Analysis of changes in heat state of female vegetable-growers within the shift helped to determine correlation between microclimate parameters (including general indicator of extrinsic heat load--WBGT index) and temperature state in the females adjusted and non-adjusted to heat. Depending on various relationships between the microclimate parameters inducing variable overheating, duration of the working shift is set for stably optimal heat state.
