Dry chemical is a powder mixture which is used as a fire extinguishing agent. It is intended for application by means of portable extinguishers, hand hose line systems, or fixed systems. ...

DEF

Bouteille métallique contenant de la poudre extinctrice, munie d'une robinetterie et mise en pression à sa fabrication ou au moment de l'emploi.

OBS

poudre sèche : D'après la source PRINC, ce terme est l'équivalent à la fois de «dry chemical» (qui désigne les poudres bonnes pour éteindre les feux de classe A, B ou C), et de «dry powder» (qui se rapporte aux poudres servant à éteindre les feux de classe D). Ce serait donc un générique. Nous tenons de plus à signaler que ce terme nous paraît pléonastique étant donné qu'une poudre, à notre connaissance, est obligatoirement un produit «sec».

OBS

extincteur à poudre : terme uniformisé par le Canadien Pacifique Ltée et par le CUTA-Opérations aériennes.

OBS

extincteur à poudre chimique; extincteur à poudre; extincteur à poudre sèche : termes uniformisés par le Comité du projet de lexiques (Nouveau-Brunswick).
