Potential Risks Affecting Personnel
This section addresses the appropriate actions to undertake when faced with
hazardous situations during or before service of the analyzer. It is not possible
to list all potential hazards within this document. The user is responsible for
identifying and mitigating any potential hazards present when servicing the
analyzer.
Mitigating risks
Refer to the instructions for each situation listed below to mitigate associated
risks.
Electrocution hazard
1. Shut off power at the main disconnect external to the analyzer and
open the enclosure.
2. Open enclosure door.
Explosion hazard
Any work in a hazardous area must be carefully controlled to avoid creating any
possible ignition sources (e.g., heat, arcing, sparking, etc.). All tools must be
appropriate for the area and hazards present. Electrical connections must not
be made or broken with power on (to avoid arcing).
Technicians are expected to follow all safety protocols established
by the customer that are necessary for servicing the analyzer.
This may include, but is not limited to, lockout/tag-out
procedures, toxic gas monitoring protocols, PPE requirements,
hot work permits and other precautions that address safety
concerns related to performing service on process equipment
located in hazardous areas.
Complete this action before performing any service that requires
working near the main input power or disconnecting any wiring or
other electrical components.
