Cohance Lifesciences Production Incharge Interview Questions and Answers

Chemistry is the study of matter, its properties, composition, and interactions.

• Chemistry involves understanding the structure and behavior of atoms and molecules

• It explores how substances react with each other to form new substances

• Chemistry is used in various industries such as pharmaceuticals, agriculture, and manufacturing

The number of batch changes in a reactor can vary depending on the production schedule and process requirements.

• The number of batch changes in a reactor is typically determined by the production plan and the capacity of the reactor.

• Factors such as reaction time, temperature, pressure, and product yield can also influence the frequency of batch changes.

• For example, a reactor used for continuous production may have fewer...read more

There are several classes in safety, including general safety, chemical safety, fire safety, electrical safety, and more.

• General safety covers basic safety practices and procedures for all employees.

• Chemical safety focuses on handling, storing, and disposing of hazardous chemicals.

• Fire safety includes fire prevention, evacuation procedures, and proper use of fire extinguishers.

• Electrical safety involves safe practices ...read more

ALCOA stands for Attributable, Legible, Contemporaneous, Original, and Accurate in the context of data integrity.

• Attributable - Data should be traceable to its source.

• Legible - Data should be clear and easy to read.

• Contemporaneous - Data should be recorded at the time of observation.

• Original - Data should be the first recording of the information.

• Accurate - Data should be error-free and true to the actual observation.

Heat transfer is the movement of heat from one place to another due to a temperature difference.

• Three types of heat transfer: conduction, convection, radiation

• Conduction is the transfer of heat through a material without any movement of the material itself

• Convection is the transfer of heat through the movement of fluids (liquids or gases)

• Radiation is the transfer of heat through electromagnetic waves

• Examples: Conductio...read more

Distillation is a process used to separate components of a liquid mixture based on differences in boiling points.

• Distillation involves heating the mixture to create vapor, then cooling the vapor to condense it back into liquid form.

• The components with lower boiling points will vaporize first and be collected, while the components with higher boiling points will remain in the liquid phase.

• Types of distillation include s...read more

There are various types of heat exchangers including shell and tube, plate, and finned tube.

• Shell and tube heat exchangers are commonly used in industrial applications due to their high heat transfer efficiency.

• Plate heat exchangers are compact and efficient, often used in HVAC systems and refrigeration.

• Finned tube heat exchangers are used when space is limited and increased surface area is needed for heat transfer.

• Oth...read more

Type A cleaning refers to a thorough cleaning process that involves removing all visible dirt and debris from a surface.

• Type A cleaning involves cleaning surfaces to a visibly clean state

• It typically includes dusting, wiping, and scrubbing to remove dirt and debris

• Type A cleaning is often required in industries like food production and pharmaceuticals to maintain cleanliness standards

Type B cleaning is a cleaning process that involves the removal of visible dirt and debris from surfaces.

• Type B cleaning is a basic level of cleaning that focuses on removing visible contaminants from surfaces.

• It does not involve disinfection or sterilization.

• Examples of Type B cleaning include sweeping, dusting, and wiping down surfaces with a damp cloth.

To handle safety in production, it is important to follow safety protocols, conduct regular inspections, provide proper training, and maintain a clean and organized work environment.

• Follow safety protocols and guidelines provided by the company and regulatory bodies.

• Conduct regular inspections to identify and address any potential safety hazards.

• Provide proper training to all employees on safety procedures and protocol...read more
