Step-by-Step Procedure for Sampling 1. Issuing a Notice o Before taking the sample, the officer must serve a notice (in a prescribed format) to the occupier (person in charge of the facility) or their agent. 2. Dividing the Sample o The collected sample must be divided into two parts in the presence of the occupier or agent. 3. Sealing and Signing the Sample o Each part of the sample must be placed in a container, which is then sealed and signed by both:  The officer collecting the sample.  The occupier or their agent. 4. Sending the Sample for Analysis o One part of the sample is sent immediately to a recognized laboratory for testing:  For Union Territories: The sample goes to a Central Board-recognized laboratory (Section 16).  For States: The sample is sent to a State Board-recognized laboratory (Section 17). o The second part is sent to a separate laboratory upon the occupier’s request:  For Union Territories: Laboratory specified under Section 51(1).  For States: Laboratory specified under Section 52(1).
