Ordinance No.42 of 1972 concerning hazards of oxygen deficiency.
This ordinance under the Japanese Industrial Safety and Health Act 1972 lays down various safety measures to be observed in work where there is an oxygen deficiency hazard. Sections are devoted to: monitoring oxygen levels in the work environment; ventilation; lifelines; respiratory protective equipment; special safety measures to be taken for work in tanks and enclosed spaces and other special types of work; training of foremen and supervisors.

CIS 72-2211 Safe work in confined spaces
Veilig werken in besloten ruimten [in Dutch]
The introduction reviews the hazards of work in tanks (poisoning, explosive gas/air mixtures, asphyxia, etc.). The main body of the document is devoted to safety measures and is divided into a number of chapters dealing with the following subjects: access openings; permits to work; measures to be taken before entering a tank; wind direction and meteorological conditions, elimination of dangerous substances, choice of fan, measurement of gas concentration, electrical equipment, ventilation, etc. Other sections are devoted to personal protective equipment (respiratory protective equipment, protective clothing, etc.), and signalling. Extracts of the relevant Netherlands legislation are included.

Maintaining air purity at the welder's work point in shipbuilding by use of the IWO-8 ventilation system
Zapewnienie czystości środowiska powietrznego na stanowiskach pracy spawaczy okrętowych za pomocą urządzenia wentylacyjnego IWO-8 [in Polish]
After reviewing the various techniques available for the ventilation of shipbuilding welders' work points, the authors indicate the requirements to be met by a local exhaust ventilation system and describe the device designed for welding in confined spaces to which access is difficult, and in tanks. This system, the "IWO-8', was suitable in field trials and reduced welding fume concentrations in double-bottoms and ships' tanks to below prescribed levels.

Fatal accidents in a sewer access shaft
Tödliche Unfälle in einem unterirdischen Kanalschacht für Dränagewasser [in German]
With reference to the relevant Federal German safety regulations, the authors comment on an accident in which 2 workers died asphyxiated in a sewer access shaft. They conclude that the air in the shaft had not been tested and that the workers were wearing neither lifelines nor respiratory protective equipment when they entered the shaft. The authors attribute these faults to a lack of staff training. Atmospheric analyses in the shaft in which the accident occurred revealed the presence of high concentrations of methane and carbone dioxide and a low oxygen concentration.

Fatal poisoning and other health hazards connected with industrial fishing
The literature on disease and severe or even acute poisoning due to work in confined spaces with trash fish used for fish-meal production is reviewed and 3 cases of fatal hypoxia in fishing boats and several cases of non-fatal illness in trash-fish handling are described. A survey carried out on air composition in the holds and forecasting of Danish fishing boats is described; in several instances, the low oxygen and/or high carbon dioxide and hydrogen sulphide concentrations encountered were considered hazardous to life. The poisoning hazards seems greatest during the landing of trash-fish or trash-fish processing in meal plants. Persons under the influence of alcohol may be particularly susceptible. Raw material quality should be improved, safety belts and lifelines should be provided for work in confined spaces, mechanical ventilation should be employed and air testing carried out; fishermen should have an adequate medical service.

Physical environmental factors in welding shops
Fyzikální klima ve svařovnách [in Czech]
Study of physical environmental factors (dust, noise, temperature, airspeed) during welding work on large parts, inside enclosed spaces or in poorly ventilated premises in 6 welding shops showed that dust is the greatest hazard, that dust concentrations in the breathing zone of welders in confined spaces were 40 times the Czechoslovak TLV (10mg/m3), and that only during weld grinding did noise exceed the maximum acceptable levels. The results are tabulated.
