A protective apron for users of 32P.
An apron constructed of several layers of foam-backed vinyl stopped 94-99% of 32P radiation and weighed about 3lbs. The apron is recommended as additional protection for personnel handling the isotope for biochemical applications. Products used in the upholstery trade as truck-seat or roof-top materials, gave the most effective protection.

Heat-protective clothing - Purpose, design and use
Hitzeschutzkleidung - Aufgaben, Gestaltung und Einsatzmöglichkeiten [in German]
Heat-protective clothing should both be effective against high tgemperatures and radiant heat and risk of injury, and ensure freedom of movement and thermal regulation of the body. The design should take the characteristics of the workplace, the muscular load associated with thermal stress, and the duration of the work into account (details are given of thermal loads in the vicinity of steel furnaces). The characteristics of flameproof cotton fabrics, and especially the influence of wear, washing and heat radiation on the protective effect, are analysed. In extremely severe conditions of radiant heat combined with the risk of flying molten particles, only aluminised fabrics ensure sufficient protection, but their use aggravates the heat load to which the wearer is subjected. The physiological limits of heat stress are shown.

Protective clothing and thermal stress.
Controlled experiments with 3 types of garment are reported: chemical/bacteriological suit (moderately thick carbon-impregnated felt); ionising radiation protection (a cotton boiler suit and a plastic coverall in combination with respiratory protection); plastic suit covered with reflective metallised plastic sheeting or with cotton towelling. The considerable thermal stress caused by chemical/bacteriological protective clothing could be lessened by wetting the cloth. Wetting the water-absorbent radiation protective garment extended the time it was possible to work in dry heat. The very limited endurance of a person working in a plastic suit was greatly increased by the use of a wetted cotton oversuit. Reflective protection was moderately effective.

Physiological research on clothing - 3. Heat transfer properties of various types of waterproofed clothing
Beklädnadsfysiologiska undersökningar - 3. Värmetransporten i olika typer av regnplagg [in Swedish]
Exercise tests carried out in a climate chamber to determine the thermal insulation properties and water-vapour permeability of 4 fabrics. Values measured: skin temperature, body temperature, weight loss, water-vapour pressure gradient, oxygen intake. Subjective comfort depended on water-vapour permeability. The lower the resistance to this permeability, the wider the possibilities of using the waterproofed clothing.

Physical research on clothing - 2. A new method for determining water-vapour permeability
Beklädnadsfysiologiska undersökningar - 2. Ny metod för bestämning av beklädnadens ångmotstånd [in Swedish]
Description of a method developed to determine water-vapour permeability, which is closely related to sweat evaporation. Calculation of resistance to this permeability is based on the relation between the water-vapour pressure gradient through the clothing and the heat flow carried by the water vapour from the skin to the ambient air. The heat flow is measured in a climate chamber by weighing (precision 0.1g/min) a subject performing an exercise test. A new method based on measurement of the partial pressure of the oxygen in the air is used to measure the water-vapour pressure gradient.. The air at the skin surface is sampled in an O2 analyser.

The permeability of protective clothing materials to benzene vapor.
The permeability coefficient of benzene vapour was calculated from the solubility and diffusion coefficients of natural rubber, nitrile, neoprene, natural rubber plus neoprene, butyl rubber, polyvinyl chloride, and polyethylene membranes determined experimentally. For rubber the permeability coefficient was 4.2 x 10-10cm2/s at a benzene concentration of 10ppm: i.e. a worker completely clothed in 0.0254cm natural rubber suit would be exposed via the skin to 0.3µg benzene over 8h. At low vapour concentrations, exposure via the respiratory tract is likely to be greater than that via the skin if the worker is suitably clothed.

Study of the absorptance coefficient of aluminised fabrics
Contribution à l'étude du coefficient d'absorption des tissus aluminisés. [in French]
The hemispheric energy absorptance coefficient of reflecting fabrics used for heat-protective clothing is measured by using of a black-body radiator. The results are independent of the type of heat source and the environment. Measurements were made with samples of new and worn aluminised fabrics produced by various processes, which are described. The results permit the best aluminisation procedures and the strongest and most effective fabrics to be identified.

Health hazards of asbestos protective clothing
Pathologie de l'amiante et vêtements de protection. [in French]
Two cases of pneumopathy (malignant pleural mesothelioma and pulmonary asbestosis with calcified pleural plaques) associated with the wearing of asbestos gloves are reported. In both cases the presence of ferruginous bodies with a visible central fibre was established. The hazards of other types of asbestos clothing are discussed. The chief prevention measures recommended are: prevention of release of pathogenic fibres by means of better production methods for fabrics and clothing; discarding of protective clothing as soon as it shows signs of wear. The importance of medical prevention and early detection of pneumopathies associated with asbestos is stressed.

Protective clothing for industrial workers subjected to high temperatures.
Considerations on flame-proof outfits available in West Germany, for protection against normal industrial heat and fire (air temperature 50-200°C, radiation intensity 0.05-0.5cal/min2 with flames of 1,500°C, and where contact heat of 200°C has to be withstood for 3s) and severe industrial hazards (similar values for flames and contact heat, but higher air temperature (100-600°C) and radiation intensity 0.4-1.0cal/cm2). Some flame-proof treatments for fabrics are not wash-resistant (non-permanent), and sweat lessens the amount of protection; other semi-permanent treatments, including "Alfamman" and "Perpregnol", can resist a limited number of washes and dry cleaning. The "permanent" category (resistant to washing and dry cleaning) includes "Proban" and "Pyrovatex", which are resistant to boiling. Reference to International Wool Secretariat flame-proof treatment (Zirko process) where woollen fabrics are treated with mixtures of zirconium and titanium.

Physiological studies on clothing - 1. Determination of thermal insulation power
Beklädnadsfysiologiska undersökningar - 1. Bestämning av beklädnadens värmeisolerande förmåga [in Swedish]
The thermal insulation power of clothing is determined by indirect calorimetry. This is calculated by dividing the temperature gradient skin-ambient air by the heat dissipated by radiation and convection. The heat dissipated results from an equation of the heat balance of the body, taking into account the energy metabolism, physical exertion, heat loss by sweating and exhalation, and heat accumulation in the body. Measurements are done in a climatic chamber.

Insulated boots - Field and laboratory evaluation.
Description of tests on knee-length insulated fire fighters' boots and aluminised reflective spats to be worn with aluminised protective clothing for aircraft crash fire fighters. These boots incorporate a layer of insulation (urethane foam, wool fleece, or vinyl foam) around the foot and ankle. The boots were evaluated and compared with standard fire fighters' boots for protection afforded, comfort, convenience and durability. Test procedures are described, and heat transfer values of insulated and uninsulated boots are given. Insulated boots are more protective; reflective spats are absolutely necessary if fire fighters are immobilised and exposed to high infrared heat pulses for 30s or longer; heat-reflective surfaces cease to function effectively when soiled (daily cleaning).

Estimation of health hazard of low concentrations of asbestos-containing dust
Beitrag zur Einschätzung des Gesundheitsrisikos durch asbesthaltige Stäube bei niedrigen Staubkonzentrationen [in German]
Studies on contamination of work clothing during work with asbestos where low levels of dust are produced show that asbestos fibres are deposited on and penetrate into the textile, and may be emitted from the work clothes unless washed. The results lay emphasis on the need for regulation of the handling, wearing and cleaning of protective work clothing in asbestos-exposed workers. Short exposures, or exposure to low concentrations of asbestos, are not always without risk. The relation between the maximum admissible concentration and environmental situations where there is no excessive cancer hazard is 1000:1. The limit value for prevention of the carcinogenic action of asbestos is to be found in this range.

Gas protective clothing - Selection of models and design criteria.
Since a general-purpose suit cannot be made, some models of gas protective clothing must be developed meeting the specific requirements. Taking the most important users' requirements and the design criteria into account, 2 suit designs are described with special reference to the selection of materials, the structure and design of the suit material and the quality control standards. The connection of gloves and boots, of heavier design to meet special requirements, to the suit allows easy and rapid replacement. Possibilities of suit ventilation are reviewed; ventilation should be used only when mobility of the suit wearer is of secondary importance. Final remarks on the maintenance and tightness testing of gas protective suits.

Effect of helmet underhats on the attenuation of earmuffs
Kypärän alushupun vaikutus kuulonsuojainten toimintaan [in Finnish]
3 types of earmuffs and cloth and fur underhats were studied by using 13-15 chain saw operators. The difference in attenuation with and without the underhat was measured as the change in the hearing threshold of the subject with Békésy audiometry. An artificial ear (IEC 318 standard) was used for measuring the 1/3 octave band noise at -10° to -20°C. The attenuation of the earmuffs was determined at 20° and -15°C by a miniature microphone attached to the ear tip. The cloth underhat decreased the attenuation by 5dB and the fur hat decreased it to almost zero at frequencies below 1.5kHz. At higher frequencies there was some attenuation with the fur hat and it increased about 15dB/octave. When the earmuffs were against the skin under the hat, the attenuation increased about 24dB compared to the attenuation with earmuffs and without the hat. In the cold environment the attenuation increased at low frequencies and decreased at high frequencies. English summary.

The wonder of wool.
This article reports on recent evaluations by the International Wool Secretariat on the thermal protection offered by two-layer assemblies of wool, synthetic and blended fabrics (7 flame-retardant outerwear woven fabrics in various combinations with 6 knitted wool or aramid fabrics). The outerwear fabrics were 100% flame-retardant wool, 85% flame-retardant wool/15% glass fibre, 100% aramid, 100% flame-retardant rayon and 100% novoloid. Nearly 90 combinations were subjected to a test similar to the draft American Standard Test Method for heat protective clothing. Protective clothing consisting of flame-retardant wool assemblies gave better protection against convective heat from flames than other flame-retardant fibre combinations of similar weight and construction. Wool gives the longest pain/blister alarm time between the onset of pain and receipt of a second degree burn. The pain/blister alarm time for Zipro wool fabric was 24.6s compared with 5.9s for novoloid, 5.2s for flame-retardant rayon, 3.3s for aramid and 1.5s for flame-retardant cotton.

Use of a ventilating hat.
A hat designed to reduce the heat stress of outdoor workers exposed to solar radiation is described. It is made up of a double sheet forming a soft crown, with a lining and 2 openings for ventilation. A disk with a wet pad on it is attached to the top of the hat producing a chimney effect. Experimental and field tests showed the ventilation effect to be positive in terms of increased air flow rate between the hat and the head, and of the slower increase of inside temperature.

The authors examined 2,500 rubbings from radiation protection clothing, and from the palms of personnel employed in 112 radiology services. The air of 92 X-ray rooms was monitored. Considerable quantities of lead were detected on door handles and on gloves and other personal protective equipment. There was a direct relationship between the level of lead contamination, on the one hand, and the amount of lead-containing protective equipment used and how long the equipment was kept in use, on the other. The following preventive measures are proposed: compliance with the specified service life of protective equipment, wearing of cotton gloves when using lead/rubber protection, enamelling (2 coats) of lead surfaces, thorough washing of hands and wrists on coming off duty.

Report of a research programme, in which a number of young volunteers participated, to investigate the physiologically tolerable limits of heat loss from some cooled areas of the body surface (chest, back, lumbar region, proximal regions of the thighs) and to calculate the required thermal insulation. These zones were cooled or heated by attaching rubber jacketting (surface area: 500cm2) filled with water at temperatures of 10-35°C. Total compensation for heat loss by local cooling was observed at a skin temperature of 29°C, heat flow being 90W/m2. Partial compensation was observed at skin temperatures above 20°C, and after heat flow had increased to 170W/m2. The thermal insulation provided by the water-cooled suits in the body areas studied should correspond to 1clo when the temperature of the cooled zone is 25°C, and 4clo when the cooled zone temperature is 10°C.

Ignition hazard of work clothes in the electric arc
Brandgefahr von Arbeitskleidung im elektrischen Lichtbogen [in German]
Tests on the behaviour of textiles exposed to fire (see also CIS 78-195) with samples of pure cotton or polyester-cotton (65%/35%) are reported. Combustion and extinction characteristics of these fabrics are different. A 65% polyester content slows down combustion of the fabric and improves the extinction characteristics, but has the disadvantage of melting, with resulting aggravation of burns. A blended fabric is as suitable as pure cotton for work clothes for routine use. In the event of high risk, the use of personal protective equipment is recommended.

Physical work in a hot environment in coal mines
Travail physique en ambiance chaude dans les charbonnages. [in French]
Neither rationalisation of ventilation nor air conditioning can solve all the problems in coal seams where there are severe climatic conditions. In the case of an effective temperature of less than 35°C and a low velocity air flow (0.5m/s), merely stirring the air by ordinary ventilation is enough to improve conditions considerably. With temperatures above 35°C, however, either the air blowing on the individual worker must be cooled, or else the worker must wear cooled clothing. Research in this field has shown that priority must be given to cooling the head and trunk, that cooling by dry ice is very effective but is ergonomically unsatisfactory, and that the simplest and most effective solution is to issue workers with a hooded jacket of double sponge fabric soaked in cold water (15°C). This article is illustrated by many tables and graphs showing, in particular, pulse rate variations when different types of cooled suits were worn.

Measurement of the clothing ventilation index.
The volume of air flowing through protective clothing has an important influence on heat loss from the body and thus on thermal comfort. A new procedure is described for estimating, under working conditions, the air flow through a garment assembly. It is based on 2 techniques, one giving a measure of the volume of the microenvironment, the other using a tracer gas to measure the rate of air exchange. Multiplication of the results yields the air exchange in l/min. This ventilation index is proposed as a descriptor of garment performance.

Body temperatures in relation to heart rate for workers wearing impermeable clothing in a hot environment.
Under conditions of high environmental temperature, the addition of a vapour-impermeable clothing barrier may greatly increase the heat stress for the wearer, and heat exhaustion may rapidly occur. Under such conditions, skin temperature in 10 healthy male volunteers reached 37.2±4°C after 30min at rest. Walking increased the rectal and skin temperature to 38.4 and 38.°C respectively after 30 min, and the heart rate was 162 beats/min. These responses did not reach a plateau after 30 min, and rectal temperature continued to rise after the subjects stopped walking. If rectal temperature is used as an index of work safety, a low rectal temperature is required when impermeable clothing is worn in a hot environment.

The cooled jacket - A further step in humanisation of working life
Die Kühlweste - ein weiterer Schritt in der Humanisierung des Arbeitslebens [in German]
Wearing of a cooling jacket is necessary in all cases where air conditioning is not feasible or too expensive: manual work deep mines and the metallurgical industry; maintenance work on blast furnaces and boilers, fire fighting and mine rescue operations. The design and operation of a liquid-cooled jacket for the head and upper part of the body is described briefly. The physiology of heat regulation is reviewed, with details of calculation of heat exchanger capacity, and construction and operation of the liquid pump and the gas motor, which form a functional unit. The jacket contains plastic tubing carrying the cooling liquid, a silicone oil.

Flameproof clothing for rescue teams
Vêtements antiflammes pour sauveteurs. [in French]
Research was carried on in laboratories in France, Germany (Fed.Rep.) and Belgium to develop protective clothing for mine rescue teams, capable of being worn for at least 1h in high temperature conditions and affording protection against certain types of explosions. A first selection between available fabrics was made by laboratory tests to determine, for a constant heat flux, the resistance of the material to the flame and to the heat flux. Tests for portability and wearing qualities in actual rescue work conditions enabled a second choice to be made. Finally, explosion tests in mine galleries (14m2 and 5m2 section) showed that at present the best equipment in ambient temperatures below 30°C was an outer garment of Baumwoll-Moleskine worn over a suit of "Doppel Frottee (Schiesser)", and that for temperatures above 30°C the same inner garment should be worn, but soaked in 400% of its weight in water. Appendices: rescue worker's fatigue index, list of fabrics tested, test results.

Safety limits for a firefighter proximity suit
A standard one-piece firefighter proximity suit (without supplemental air or cooling) was tested under simulated "standby" conditions for heat accumulation and hood compartment ventilation. Large increases in temperature of the skin and the air in the hood were recorded. Oxygen and carbon dioxide levels indicated hypoxic conditions. Time exposures allowed for firemen entering various ambient conditions were calculated: the shortest permissible exposure periods predicted suggest limited usefulness and the need for immediate improvements in the design of the suit.

Development of performance criteria for protective clothing used against carcinogenic liquids.
These criteria are the first intended to assist in the manufacture, selection, and testing of materials to protect workers for at least 60min against the hazards. A simple test was developed to evaluate permeation resistance of natural and synthetic rubbers, polyethylenes, fluorinated and vinyl plastics. Other tests challenge the strength, chemical ageing, thermal resistance, flexibility and cleanability of clothing materials. The carcinogenic substances used were trichloroethylene, epichlorohydrin, coal-tar creosote, benzene, ethyleneimine, 1,1-dimethylhydrazine, 2-nitropropane, β-propiolactone and hexamethylphosphoramide. Many present materials did not meet the criteria. The report recommends the set of test methods described to be adopted as standards by which protective clothing used against chemicals are evaluated, and that in the case of clothing used against carcinogens a minimum time of protection of 60min (8h for clothing used in emergency situations) be adopted as standard. Other recommendations concern dissemination of information on protective materials, and use of solubility tests as screening procedures. Appendices contain properties, uses and exposures of the carcinogens; test method details.

Evaluation of the effects of a cooling garment on adapatation to prolonged effort by miners at high temperatures
Evaluation des effets d'un vêtement refroidissant sur l'adaptation aux efforts prolongés réalisés à haute température par des ouvriers mineurs. [in French]
To improve working conditions of miners at high temperatures, the efficacy of a cooling garment consisting of a jacket and hood of towelling material soaked in cold water was studied. Eight miners underwent effort tests in a climate chamber under simulated mine conditions. Wearing the garment reduced the heart rate to 104 beats/min after effort as compared with 125 without the garment, rectal temperature to 38.3 as against 38.8°C, and weight loss to 1.5 as against 2kg. Further, the vest was evaluated positively by all subjects, who finished the tests without undue fatigue.
