Daily checking FILM WASHING TIME: which statements are true?

• A. 1 and 2
• B. 1 and 3
• C. 2 and 3
• D. 1, 2, and 3

Answer: (B)

Daily checks of film washing time focus on making sure the rinse step reliably removes fixer residues from the emulsion. This is essential because any leftover chemicals can cause image artifacts, degrade film quality, or corrode over time. The statements that are true reflect two practical truths: the wash duration must be long enough to remove residual fixer under the actual operating conditions, and this duration should be verified daily with a standard check to keep the process consistent. Any claim that wash time can be skipped, shortened arbitrarily, or ignored because other steps supposedly handle cleanup would not fit with the purpose of the daily verification. So the two true statements are the ones that emphasize an adequate, validated wash period and daily verification of that period.
