Intrinsic Safety
Intrinsic Safety is a protection classification for equipment that
ensures there are no conditions under which the equipment can
operate that could cause a release of energy sufficient to ignite a
hazardous gas or dust mixture. Devices that meet the low power,
current-limited design criteria are deemed Intrinsically Safe (IS).
Special design, testing, quality, and inspection rules apply to
manufacturers and users of IS equipment due to the critical nature
of the equipments’ deployment in hazardous areas. Areas in which
hazardous conditions can be expected to exist on a constant basis
are categorized (rated) as Class I, Division 1, in the USA and as
Zone 0 in Europe. Some U.S. cities and states have adopted the
NFPA (National Fire Protection Association) classification that
rates sanitary sewers as Class I, Division 1, areas. Many European
Union member states have classified their sanitary sewer systems as
Zone 0 or Zone 1 environments.
The FlowShark IS (Model 5000-IS1-xx-x) flow monitor is certified
to UL standards in the U.S. and to ATEX standards in Europe, and
it is approved for use in all classified (hazardous) sanitary sewer
and industrial hazardous areas. Many rest-of-world countries accept
the U.S. or ATEX certifications in lieu of their country-specific
requirements. It is the customer’s responsibility to ensure that
the certification(s) provided for the ADS equipment meets the
customer’s regulatory requirements.
Note: FlowShark IS models include 5000-IS1-US-01,
5000-IS1-US, 5000-IS1-01, and 5000-IS1. In the
remainder of this manual, all models of FlowShark IS are
referred to as ADS Model 5000-IS1, unless otherwise
specified.
