During a lab, should the doors remain open or closed?

• A. The doors should remain open so that another person is within easy calling distance
• B. The doors should be kept closed at all times
• C. Doors should be opened only during experiments
• D. The doors should be locked

Answer: (A)

The main idea being tested is the importance of being able to get help quickly in the lab. Keeping the door open helps ensure that another person is nearby who can hear you and respond immediately if something goes wrong. Quick access to assistance reduces response time and can prevent minor issues from turning into serious hazards. While there are times when doors should be closed to contain hazards, this item emphasizes staying in contact and maintaining visibility and communication with others in the lab. Options that hinder prompt help or leave you isolated pose greater safety risk because timely support is a key part of safe lab practice.
