Final answer:
The correct answer to the safety protocol question is 'B) Locked', which refers to the Lockout/Tagout (LOTO) safety procedure to prevent unexpected ejection system activation and ensure employee safety in storage facilities.
Step-by-step explanation:
The question refers to safety protocols related to storage facilities, where an ejection system must meet certain conditions before it's safe for an employee to enter. Considering the provided options, the correct answer is 'B) Locked'. Blocking or locking out the ejection system is a safety measure taken to ensure that the system does not activate unexpectedly, causing potential harm to those who enter the storage facility. This safety precaution is part of a larger set of procedures often referred to as Lockout/Tagout (LOTO) which is crucial in industrial and manufacturing settings for the protection of employees.
When a machine or system is locked out, it is rendered inoperative or isolated from its power source. This is to prevent the release of hazardous energy which could cause injury to workers. It's very important for employees to fully test that the equipment is properly locked out before commencing any work within a hazardous area.
