Which of the following is NOT a routine standard operating procedure (SOP)?

Decontamination is primarily a procedure used in response to specific contamination incidents rather than a routine standard operating procedure. While it is crucial in hazardous waste operations to ensure safety, decontamination is activated when there is a potential exposure to hazardous substances. In contrast, lockout/tagout, confined space entry, and fire prevention are routine SOPs that are regularly implemented to manage risks, maintain safety systems, and ensure compliance with regulations. These procedures are integral to everyday safety practices, helping to prevent accidents and ensure safe working conditions across various operations. Decontamination, on the other hand, is typically utilized as an emergency response measure rather than a regular ongoing procedure.
