Which of the following is listed as a proper laboratory behavior?

• A. No horseplay in the laboratory
• B. Maintain aisles clear of objects
• C. No food or beverages in the laboratory
• D. Read before you proceed

Answer: (D)

Reading procedures and safety guidelines before starting a lab task is essential. When you take the time to read first, you learn exactly what steps to follow, the hazards you may face, the required protective equipment, and the proper emergency actions. This preparation helps prevent accidents, incorrect results, and inappropriate handling of materials. Other good safety habits, like not horseplaying, keeping aisles clear, and not eating in the lab, are important, but the act of reading before you proceed directly ensures you can perform the work safely and correctly from the start.
