Final answer:
When uncertain about a product's risk level, consulting a supervisor is the best course of action. If needed, contact the manufacturer for precise information to ensure proper handling and compliance with safety standards.
Step-by-step explanation:
When unsure of which risk level a specific product falls under, it is best to consult a supervisor. Making an uninformed guess could lead to safety hazards or noncompliance with regulations. Supervisors are usually experienced and could provide immediate and accurate information. If a supervisor is not available or cannot provide a definitive answer, contacting the manufacturer for clarification is a responsible and professional approach. This ensures that you have the most accurate information directly from the source and can assess the risks associated with the product appropriately.
