9 Special Instructions for use in
explosive atmospheres or hazardous
locations
Information in following paragraphs must be taken into account and followed by the person
responsible for the equipment installation site. Refer to the provisions of European ATEX
Directive 1999/92/EC or to the applicable local legislation, relevant to improving safety
protection and health of workers exposed to the risks of explosive atmospheres.
The installation and maintenance of the gas monitor should be performed according to
standards EN/IEC 60079-14 and EN/IEC 60079-17.
For intrinsically safe installations and especially for connections to the gas monitor, the person
responsible for the intrinsic safety installation, called the
System designer, must establish a
system document demonstrating that the entire gas monitor system - Cable - Body is Intrinsically
Safe (see standard IEC 60079-25 for the preparation of this document).
The BM 25A/AW complies with the following standards:

9.1 ATEX areas and general rules
If the device is used in a contaminated atmosphere, the catalytic sensor must be calibrated it
before its next use.
Silicon vapors or other contaminants may have an adverse effect on catalytic sensors
(slot 1) for combustible gas detection, and may distort measurements (under-
estimated measurements).
