Final answer:
The door to a hot lab must be both locked and under surveillance to ensure safety and security. This includes restricting access to maintain a safe lab environment and using surveillance to monitor for any breaches or incidents. The correct options are a) and b).
Step-by-step explanation:
The door to a hot lab must be both locked and under surveillance. When discussing laboratory safety, it is imperative to ensure that access control measures are implemented to prevent unauthorized entry and to protect both personnel and the sensitive materials within the lab.
For this reason, security protocols typically require a hot lab to be locked at all times and monitored, possibly through security cameras or personnel, to maintain a safe and secure environment.
Security Measures in the Lab
In accordance with lab safety guidelines, ensuring restricted access is crucial, especially in areas where hazardous materials are kept or critical experiments are conducted. Surveillance can help in swiftly identifying and responding to security breaches or safety incidents.
Moreover, locking the door during non-working hours is essential to safeguard against theft, tampering, or unintended exposure to harmful agents.
It's important to also observe other safety practices such as keeping long hair tied back, not eating or drinking in the lab, and knowing the location of fire safety equipment. Option a) and b) are the correct one.
