Which item should be included in an inspector's sampling toolkit?

• A. Garden Hose
• B. Tape Measure
• C. Leakproof Sampling Containers
• D. Ladder

Answer: (C)

Preserving the integrity of samples during collection is essential. Leakproof sampling containers are fundamental because they prevent spills, block external contaminants from entering the sample, and keep the sample intact from collection through transport to the lab. They also support proper labeling and chain-of-custody, which are crucial for valid analysis and traceability. Depending on the sample type, these containers should be sterile or chemically inert and appropriately sized to avoid dilution or contamination. While other items have practical field uses, they don’t ensure sample integrity. A garden hose could introduce residues or contaminants, a tape measure helps with measuring rather than preserving a sample, and a ladder assists with access but doesn’t affect the sample’s condition or transport.
