"System dependent" emergencies are characterized by:

• A. Clear SOPs to be carried out
• B. No standard procedures
• C. Immediate uncoordinated action
• D. Response by a single agency only

Answer: (A)

System dependent emergencies rely on established procedures and organizational structure to guide actions. When a response is system dependent, the outcome hinges on responders following clear, predefined steps, roles, and communication protocols. Clear SOPs mean everyone knows what to do, when to do it, and how to coordinate with others, which keeps the response organized even as the situation evolves.

Without standard procedures, there isn’t a reliable framework to depend on, so actions would be improvised and prone to confusion. A scenario characterized by immediate uncoordinated action reflects a breakdown of the system rather than reliance on it. And relying on a single agency contradicts the collaborative nature of most hazmat responses, which depend on multiple entities working together under a common set of procedures.
