According to lab procedures, when using raw materials in the lab, purchase orders must be submitted before use.

• A. True
• B. False
• C. Not applicable
• D. Depends on material

Answer: (A)

Submitting a purchase order before using raw materials is about enforcing formal procurement controls that keep track of what enters the lab. This requirement ensures an auditable record of what was ordered, from which supplier, in what quantity, and to which specification. It also ties into inventory management, budgeting, and quality assurance, helping verify that materials meet the needed standards and are authorized for use.

Using raw materials without a PO can bypass approvals, lead to mismatched or unsafe inputs, and create gaps in cost allocation and traceability. Having the PO in place before first use prevents these issues and supports accountability and compliance with lab procedures.

While some contexts might mention exceptions or material-specific rules, the standard practice described here is to require a purchase order prior to using raw materials.
