What safety protocol should be adopted for familiar lab work when alone after hours?

Choosing to ensure that emergency contacts are accessible is crucial for maintaining safety in a laboratory environment, especially when one is working alone after hours. In such scenarios, it is essential to prepare for any emergencies that may arise, whether they are related to equipment failure, accidents, or health issues. Having a list of emergency contacts readily available—such as phone numbers for nearby colleagues, security personnel, and medical assistance—provides a quick reference point to facilitate prompt help if needed.

In environments where individuals work alone, the risk of accidents can increase due to the lack of immediate support. By ensuring that emergency contacts are accessible, the individual can respond more effectively to unforeseen situations, enhancing personal safety and the overall safety of the laboratory.

Other potential safety protocols, while important, do not address the immediate safety aspect to the same degree. For instance, notifying management beforehand may be a good practice for accountability, but it does not prepare one for emergencies while working alone. Keeping the lab locked at all times is a prudent security measure but does not assist in the event of an emergency when access to assistance may be needed. Finally, never leaving the lab is impractical, as breaks or other necessary activities may require stepping out, and strict isolation could lead to serious safety risks
