| Resumen |
This data sheet, which supersedes the edition abstracted under CIS 1738-1971 Gzx Hbid Jyuz (203), applies to cellars, sump pits, open tanks, as well as sewers, which are subject to various contaminants. After describing the types of dangerous vapours and gases (fuels, fermentation gases, combustion products, drainage gases) and the hazards (explosible, flammable or poisonous gases, suffocating vapours), it contains recommendations for testing (instruments for combustible gases, oxygen deficiency, carbon monoxide or hydrogen sulfide), periodic inspection of manholes and ventilation (forced draft is preferred). Reference is made to the relevant legislation on manhole entry requirements. French translation may be obtained from INRS, 30 rue Olivier-Noyer, 75680 Paris Cedex 14, France. |
