Man
 Establishment and maintenance of satisfactory system of manufacture
and control of products and actives rely on people
 Must be sufficient qualified personnel to carry out tasks
 Individual responsibilities must be clearly defined and understood by
individuals concerned
 Written job descriptions
 All personnel should be aware of the principles of GMP that affect them
adequate number of persons
 With necessary qualifications
 With practical experience
 An individual’s responsibilities should not be so extensive as to present
a risk to quality
 All responsible staff should have specific duties recorded in individual
written job descriptions

SYSTEM
SYSTEM VALIDATION

Areas where pharmaceutical starting materials, utensils and equipments are exposed to the environment
should be classified as clean areas.
Weighing and Dispensing operations in separated area.
Smooth, impervious (not to be penetrated), durable (permanent) easy to clean finished.
Appropriate design – say
-Dispensing Booth, Balance, Utensils
-Maintain Room pressure
-Temperature Control
-Humidity Control
-Location of Air terminates and direction airflow
-Separate personnel flow
-Separate material flow
-Utensil wash, dry and storage
-Dynamic pass box
-Air lock
-Cleaning procedures and records
-Documentation, e.g. SOPs.

Dispensing Booth
To Prevent cross contamination of material by environment, human and
others during dispensing of pharmaceutical raw materials, a dedicated
and confined area under laminar air flow (LAF) unit are used that are
called dispensing booth. It facilities with conditioned air through HEPA
filter and Maintains positive air pressure in respect adjacent area to
prevent flow of external air.
Procedures
Preparatory phase
Personnel must wear clean cloths, headgear, facemask, shoe and hand
gloves before entering in dispensing area.
