Occupational exposure to hexachlorocyclopentadiene - How safe is sewage?
After a large volume of hexachlorocyclopentadiene had entered a sewage treatment plant, a number of workers immediately experienced tracheobronchial irritation. The plant was closed and workers were questioned and examined. Of the 145 workers evaluated, 85 (59%) had eye irritation, 65 (45%) headaches, 39 (27%) throat irritation. The highest attack rates were in primary sewage treatment areas. Examination revealed proteinuria and elevated serum lactic dehydrogenase levels.

Falling into the safety net.
This article, written by an official of the Health and Safety Executive (HSE), reviews briefly the new occupations now covered by occupational safety and health (OSH) legislation in the United Kingdom since the Health and Safety at Work Act 1974 (CIS 74-2099) became effective. These "new entrants" include such diverse work activities as school administration and teaching personnel, fairground workers, hospital staff, window cleaners, refuse collectors, gravediggers, etc. who received little or no protection at work under previous OSH legislation. The article refers to 4 pilot studies on some of these newly-covered activities (water services, hospital services and educational establishments, with 2 smaller studies on workers employed in fairgrounds and licensed clubs) carried out by HSE, with considerations on the aspects of: relevance of usual OSH precautions in special situations such as research laboratories; degree of protection; aims of inspection and establishment of appropriate OSH standards in these new areas.

Marseilles sewermen
Les égoutiers marseillais. [in French]
Working conditions of sewermen, underground and above ground, are studied in detail with their hazards: infection (tetanus, leptospiral jaundice, brucellosis, ankylostomiasis, poliomyelitis, tuberculosis, typhoid fever, viral hepatitis, common infections), chemical hazards (hydrogen sulfide, arsine, sulfur dioxide, chlorine, carbon dioxide and monoxide), combustion and explosion hazards related to use of acetylene lamp, physical factors (humidity, odours), and, especially, falls and drowning. Technical prevention measures: prohibition of a worker entering the sewer alone, ventilation of workplace before entry, air analyses, improved lighting. Medical prevention measures: pre-employment examinations centering on spinal radiography and haematological studies; tetanus and poliomyelitis vaccinations.

Occupational safety and health in undertakings for the collection and treatment of household refuse
Hygiène et sécurité dans les entreprises de collecte et de traitement des résidus urbains. [in French]
MD thesis. General considerations on household refuse (definition and composition; garbage collecting, transport, treatment processes, recycling); review of recognised occupational and occupation-associated diseases (tetanus, leptospirosis, dermatosis, ear, nose, throat and lung disease, backache, low back pain, gastric disorders) contracted by garbage collectors and workers engaged in refuse composting, comminution, incineration, etc. Some of these diseases have practically disappeared with progress in hygiene, and the number of accidents has decreased due to mechanisation and automation. The most hazardous operations remaining are: refuse sorting (cuts, pricks, nips) and collecting (muscular overstrain, elongation, traffic accidents). The last part of the thesis gives the results of a statistical survey of occupational accident trends in a refuse processing plant at Lille (France) (comparison with data from other French cities and France as a whole).
