The CE Mark
The Machinery Directive 2006/42/EC
prEN 842 Safety of Machinery :
Warning Signals
Danger Signals
Emergency Signals
The Moflash products that show the CE mark, are
deemed to comply, where applicable, with the EMC
Directive No: 89/366/EEC and additional
amendments, regarding Electromagnetic
Compatibility which states that ‘An electrical product
must not be susceptible to, or generate certain levels
of, electromagnetic interference liable to interfere with
other electronic equipment’, and the LVD Directive
No: 2006/95/EC regarding low voltage electrical
material which states that ‘Electrical equipment within
the voltage ranges of 50 to 1000v Ac and 75 to 1500v
Dc are constructed within the principles of good
engineering practice and provide adequate levels of
protection against an electric shock’.
These directives are designed to harmonise wide
ranging health and safety requirements in machinery
design and daily use by indicating a potential hazard
by the use of an immediately recognisable audible or
visual warning signal.
Visual Warning Signals
Classifies the type of warning light and specifies the
characteristics the warning light must achieve to
conform to the machine directive.
Visual warning signals must be at least five times
brighter than the area where they are used.
Clearly visible even in strong light, distinguishable
from other lights and Visual warning signals and be
understood immediately.
These have the highest priority and must be at least
ten times brighter than the area that they are to be
used in and understood immediately.

All Moflash coloured domes are manufactured from
‘UV’ stable polycarbonate plastic that will not tarnish,
fade or become brittle over a period of time unlike
many domes available that are produced from Acrylic
plastic.
The risk of an explosive atmosphere being formed is
obviously a variable factor being dependent upon the
conditions in a given environment. Thus in order to
achieve a consistent level of safety, hazardous areas
are classified into three zones.
Zone 0
A zone in which an explosive atmosphere is
constantly present, or present for long periods.
Zone 1
A zone in which an explosive atmosphere is likely to
occur in normal operation.
Zone 2
A zone in which an explosive atmosphere is not likely
to occur in normal operation, and if it occurs it will
exist only for a short time

Apparatus Groups (Gas Groups)
IP Ratings
The IP ‘Ingress Protection’ rating system provides a means of classifying the Degrees of protection from dust and water afforded by electrical
equipment and enclosures. The system is recognised in most countries and is set out in BS EN60529 1992 Degrees of Protection.

Apparatus for use in hazardous areas is, where
appropriate, grouped in one of four sub-groups,
namely I, IIA, IIB, IIC.Apparatus Sub-Grouping is
normally applied to Flameproof and Intrinsically safe
types of protection. Other types of protection apply
equally to all gases subject only to temperature
classification.
The following table shows the relationship between the
apparatus group and the Representative gas.

A gas/air mixture can ignite when it comes into contact
with excessively hot surface. The surface temperature
at which equipment operates is therefore of crucial
importance. The equipment is temperature classified
as follows:
Class
Max Surface
Temperature in Centigrade
Note:
Hazardous area equipment should only be undertaken by a suitably qualified
Engineer and installed according to the relevant standards.
