Zoning Diagram
Latitude pumps and dispensers are ATEX certified. The dispenser must be installed to not
compromise the zones illustrated in Figure 3-1, Figure 3-2 on page 3-4, and Figure 3-3 on
page 3-5. These zoning diagrams show the extent
of the external hazardous areas.
The zones 0, 1, and 2 indicated in th
e zoning diagrams define the probability of the hazard
actually being present in flammable concentrations.
• Zone 0:
A place in which an explosive atmosphere is present continuously or for long
periods or frequently.
• Zone 1:
A place in which an explosive atmosphere is likely to occur in normal operation
occasionally.
• Zone 2:
A place in which an explosive atmosphere mist is not likely to occur in normal
operation but, if it does occur, will persist for a short period only.
