What
is
intrinsic
safety? |
 |
|
Intrinsic
safety
is a
design
technique
applied
to
electrical
equipment
and
wiring
for
hazardous
locations.
The
technique
is
based
on
limiting
energy,
electrical
and
thermal,
to a
level
below
that
required
to
ignite
a
specific
hazardous
atmospheric
mixture. |

How is
intrinsic
safety
defined? |
|
Intrinsically
safe
equipment
and wiring
shall not be
capable of
releasing
sufficient
electrical
or thermal
energy under
normal or
abnormal
conditions
to cause
ignition of
a flammable
or
combustible
atmospheric
mixture in
its most
easily
ignitable
concentration. |
|
|
 |
|
Who
verifies
intrinsic
safety? |
| |
Equipment
is
tested
and
certified
for
intrinsic
safety
by
independent
third
party
agencies,
such
as
Underwriters
Laboratories
(UL),
Canadian
Standards
Association
(CSA),
Factory
Mutual
Research
Corporation |
|
|
(FM) and the
Mine Safety
and Health
Administration
(MSHA).
Independent
testing
ensures that
your gas
monitoring
equipment is
not only
designed to
be
intrinsically
safe, but
meets all
required
standards
for
intrinsic
safety. |
