When required, risk level 1 discharge sampling is conducted during which time frame?

When required, risk level 1 discharge sampling is conducted during which time frame?

• A. During nighttime hours.
• B. On weekends.
• C. Any time.
• D. During business hours.

Answer: (D)

Risk level 1 discharge sampling is meant to reflect what the facility normally produces during its standard operating period. Conducting the sampling during business hours ensures trained staff are on site to supervise the collection, follow proper sampling procedures, maintain the chain of custody, and get the sample to the lab within the required hold time. When sampling happens at night or on weekends, staffing, supervision, and processing can be inconsistent, which can compromise sample quality and recordkeeping. Sampling at any time would not consistently represent typical operations. So, the appropriate timeframe is during business hours.
