WARNING
EXPLOSION HAZARD Risk assessment! Perform a risk assessment
for any risks due to the process or process environment. Evaluate
the effects the use of the BioProcess column and processes have
on the classification of the hazardous area. The process might
cause the area to increase or the zone classification to change.
Implement the risk reduction measures needed, including use of
personal protection equipment.
To be considered when performing the risk assessment:
•
All personnel involved in operating, maintaining and servicing
the column must have proper knowledge of ATEX and ATEX
columns.
•
Risk of liquid leakage in case of failure or breakage of the col-
umn. Prepare procedures for handling leakages and testing
after corrective actions.
•
Risk of air entering the flow path during filling and emptying
the column which might create an explosive atmosphere when
being mixed with vaporized solvent. Make sure that the liquid
flow path always is filled with 20% ethanol between runs.
•
Risk of smaller leakages during maintenance. Make sure there
are no active ignition sources in the area during maintenance.
