Perform scheduled cleaning, filter replacements (HEPA/pre/return), belt tightening, lubrication, and inspection tasks.
Support senior technicians in servicing AHUs, ductwork, chillers, and diffusers.
Record maintenance tasks in logs and CMMS as per standard procedures.
Assist in maintaining required pressure differentials between classified areas (positive or negative pressure zones).
Ensure systems comply with cleanroom standards (ISO 14644, GMP, or equivalent).
Respond to deviation reports or temperature/humidity alerts from critical environments.
Follow strict personal hygiene protocols when entering cleanroom zones.
