Application Note

goal is to promote sharing of
information on current safety
and health topics of c
ommon
interest.
Intrinsic safety is covered
under Regulations (Standards -
29 CFR), Hazardous (classified)
locations 1910.307 and
1926.407. OSHA references the
NEC guidelines for determining
the type and design of equip-
ment and installations which
will meet this requirement.
There are no global intrinsi-
cally safe standards or
c
ertifications.
Who is affected by the
ATEX intrinsically safe
standards?
Currently the standard affects
only manufacturers who are
selling product into the
European Union (EU) that are
intended for environments
subject to explosion hazard.
Considering the joint effort of
OSHA and the EU, the long-
term effect of ATEX may be a
global standard to which all
manufacturers would need to
comply.
What is the impact of
ATEX on manufacturers?
For manufacturers selling
devices designed to be used in
potentially explosive env
iron-
ments into the EU, they will
need to redesign the devices to
meet the standard and ha
ve
those devices certified that
they meet the regulations.
Manufacturers not selling
product in the EU are not
impacted.
Why is there so much
interest in intrinsically
safe products now?
The new ATEX regulations
have focused attention on the
issue of providing intrinsically
safe products in potentially
dangerous environments.
However, there has already
been a great deal of attention
placed on workplace safety by
regulatory groups as well as
manufacturers.
Fluke has always focused
strongly on safety in all its
products. The company has
sought industry-wide protec-
tion measures to help ensure
safe working conditions and
product specifications for elec-
trical technicians, whatever the
field in which they work.
The Fluke 707Ex mA
Calibrator is the first test tool
from Fluke developed specifi-
cally for use in hazardous
environments such as petro-
chemical plants, oil platforms
and refineries and other loca-
tions subject to risk of
explosion.
The ATEX-compliant 707Ex
mA Calibrator is compliant in
relation to Zones 1 & 2 as
defined by CENELEC (the
European Committee for
Electrotechnical Standardization,
which is rec
ognized by the EC
as the European Standards
Organization in its field). In
these zones hydrocarbons
and/or gases may be present
during either normal or abnor-
mal operation, respectively.
This means that in Zone 1
potentially explosive atmos-
pheres ma
y b
e present
oc
casionally, while in Zone 2
they may be present only
rarely and w
ill b
e of a short
duration.
