Translation of "Nettoyage par jet d'eau sous pression " (French → English) :

‘The troughs and hoppers must be washed using high-pressure water jets before each day’s harvest is unloaded and whenever it is deemed necessary’.

These include the confluence of Bantu/Nilotic, Arab, Egyptian and Abyssinian cultures; the large number of wars over secession, autonomy or territorial claims (many of them related to ethnic or religious identity), control of resources and disputed borders; the regional impacts of population growth, climate change and related pressures on natural resources; the friction fuelled by competition for the water resources from the Nile; the high proportion of nomadic pastoralists, bound largely by ethno-linguistic ties rather than political borders, who are among the most marginalised groups ...[+++] in the region; a culture of militarism and certain vested interests in war economies; and the neglect, underdevelopment and insecurity of border areas in the region.

- high pressure water jet machines

Both rigid and flexible pipes carrying fluids, particularly those under high pressure, must be able to withstand the foreseen internal and external stresses and must be firmly attached and/or protected against all manner of external stresses and strains; precautions must be taken to ensure that no risk is posed by a rupture (sudden movement, high-pressure jets, etc.).

If the compressed air is obtained from pressurized receptacles used to operate the vessel or for other purposes, or produced by means of compressors, an air filter or oil separator must be installed directly in front of the pressurized water cistern unless the water and the air are separated by diaphragms.

11.12.6. Pressurized water cisterns for potable water must operate only on compressed air of natural composition.
