The collection of vibration data from general plant.

1. |
|
The collection of vibration data necessitates the plant being in a working condition,
and as such measurement points are positioned to keep personnel in a safe position. Accelerometers are attached
(either by screw fitting or magnetically) to the designated measurement point, the inter-joining cable is then
plugged into a portable data collector and vibration data is collected. The instrumentation is then removed, and
fixed to the next measurement point. Guards are not to be removed from
moving machinery. |

|
Measurement points which are by necessity behind guards will normally be monitored
by the installation of remote accelerometers with cables fitted bringing the measurement point to a safe place. |

The use of 'tube spanners' of appropriate length to allow the attachment of magnetically
mounted instrumentation to machinery through mesh guarding will be discussed on site prior to use, and only used
with the agreement of site safety personnel that their use does not give rise to any appreciable risk. |

Occasionally, it may be necessary to monitor equipment with restricted access (for
initial investigative work for example). In this case the machine is to be stopped, isolated and locked off (a
permit and the assistance of site personnel will be required for this). Any guards can then be removed, temporary
instrumentation attached with an appropriate length of cable to enable personnel to complete data collection from
a safe place. Any guards will be re-fitted before the machine is restarted to collect data. On completion, the
machine is to be stopped, isolated and locked off to enable the instrumentation to be removed. At any time whilst working behind guards the plant is to be isolated and the operator kept
informed of action being taken. |
