Good Laboratory Practices The exact definition depends on who is defining it and for what purpose. A broad definition encompasses such issues as organization of the laboratory, management, personnel, facilities, equipments, operation, method validation, quality assurance and record keeping .

Good Laboratory Practices The goal is to certify that every step of the analysis is valid. The aspects that need to be particularly addressed will vary by laboratory.

Good Laboratory Practices Good Laboratory practices can be defined as “a body of rules, operating procedures and practices established by a given organization that are considered to be mandatory with a view to ensuring quality and correctness in the results produced by a laboratory.

Good Laboratory Practices Established by worldwide bodies such as Organization for Economic co-operation and Development (OECD) International Organization for Standardization. (ISO)

Good Laboratory Practices Government agencies have adopted them as rules for laboratories involved in analyzing substances that require regulation. e.g. pharmaceuticals, foods, environmental samples etc.

Good Laboratory Practices Good Laboratory practices in chemical laboratory as a compliance to GMP requirements. Schedule L-1 requirements for GLP

Cleanliness Control laboratories & equipment should be kept clean., in accordance with written cleaning schedules. All laboratory personnel should wear clean protective clothing appropriate to the duties being performed. The disposal of waste material should be done carefully & responsibly in accordance with procedures which should be documented. Keep the work place clean & uncluttered& do not get distracted at work by other people.

Premises Located, designed, constructed or adapted 7 maintained to suit the performance of all quality control tests & analysis required before, during & after manufacture. Away from external & internal traffic.

Reagents The reagents should be dated upon receipt or preparation & labelled for identification. Reagents made up in the laboratory should be prepared by competent persons according to laid-down procedures. The labels on the reagent bottles should indicate the concentration, standardization factor, shelf life & storage conditions , date of preparation, date of re-standardisation & signature of the chemist who has prepared it. Reference standards & working standards should be dated & stored at proper conditions. They should be handled & used carefully in consultation with senior chemist. MSDS of hazardous & poisonous chemicals Distilled /DM water- analysis

Equipments Laboratory instruments & equipments should be serviced & calibrated at suitable intervals according to written procedures by persons or a service agency & validated. (SOP for operation & calibration) Readily available records must be maintained for each one of them. Next servicing or calibration due date should also be mentioned on them. Separate room under control temp. & humidity

Equipments Written operating instructions should be readily available or preferably be displayed for each instrument. Records shall have Name of eqip., Mfg.’s name & instruction manual, model no.,list of spares &accessories, etc. Defective instrument should be withdrawn from use until the fault has been rectified.

Sampling Sample should be a proper representative of bulk product. A trained & authorized sampler should sample out using appropriate , clean Sampling equipments , following safety precautions & sampling norms.

Sampling Written Sampling SOP should include Method of sampling Equipment to be used The amount of sample to be taken Instructions for any required sub division of sample The type & condition of sample container to be used Any special precaution to be observed Cleaning & storage of sampling equipment.

Sampling The Sample container should have labels bearing details about Name of material, Batch no., Mfg. Date, expiry date , Name of manufacturer,& quantity sampled. Those containers from which samples are drawn, are marked with ‘sampled’ stamp with date & signature of the chemist so that they are identifiable from bulk containers. Sampling equipments should be cleaned after each use & stored separately from other laboratory equipments.

Documents All the departmental systems & procedures , specifications for all input materials, intermediates & finished products & all tests and methods of analysis should be documented. All raw data, formats of analytical reports , under test, approved & rejected labels , various in-process checks , calibration check records should be documented & available. Archives for storage,& retrieval of records. Retention time should be maintained.

Procedure & documentation Method of analysis & specifications SOP for systems, instruments Reports- Analytical reports of batch, stability report, working standards, validation reports, Monitoring quality of water, effluents discharged, RM, In-process, FP.

Standard Operating Procedures To store data in paper format, humidity conditions shall be maintained. Data in the form of disc & tape should be stored with care. For storage on optical disc, its life shall be longer than storage time. Keep a photocopy of data on thermal paper.

The aim of documentation is To define specifications for all materials, method of manufacture & control To inform all concerned mfg, personnel how when & why a batch is rejected. To provide audit trail for to permit investigation of any suspected defective batch.

Documents Documents shall specify the title, nature & purpose. They shall be laid out in an orderly fashion & easy to check. Documents shall be approved, signed, regularly reviewed, and dated by appropriate & authorised person.

Records Raw data refers to records of original observations. Make detailed records of the results of the tests & analyses of all materials, intermediates & finished products & in process tests done, environmental monitoring, calibrations etc. Changes or corrections in the entry should be single line strike. Authorised persons will have access to data to maintain its integrity & security.

Records Records should have following details. Analytical report no. Name of the sample Date of receipt of sample Batch/lot no. Protocols of tests applied Signature of the analyst Opinion & sign of approved analyst Any other relevant & extra information e.g. date of expiry , date of release & in case of drugs, requirements complying schedule U Records should also contain the basic data & calculations from which test results were derived.(e.g. weighings, readings, recorder charts, instrument printouts etc.)

Testing Samples should be tested in accordance with the written methods & referred to in relevant specifications. In- process checks done by QC personnel on the batches in production should also be attached to the analytical reports for the batch. Test methods should be validated. Where the results of testing appear doubtful, repeat the test/s but do not fabricate the results to cover up mistakes or to avoid work.

Good house keeping & Safety People working in the laboratory should look after safety aspects of their work for themselves, their colleagues &the organization. They should wear appropriate safety gadgets while working with hazardous , corrosive chemicals & inflammable solvents. Persons in the department should be trained to operate fire fighting apparatus. Persons in the department should be familiar to first-aid techniques in case of emergency till medical help is available.
