ISM stands for which of the following?

• A. Integrated Safety Management System
• B. Incident Safety Management System
• C. Integrated Security Management System
• D. International Safety Management System

Answer: (A)

The main idea being tested is understanding what the acronym ISM stands for in safety management contexts. The best fit is Integrated Safety Management System because it conveys a holistic, organization-wide approach that weaves safety into policy, planning, operations, training, and continual improvement. This kind of system links hazard identification, risk assessment, controls, incident reporting and investigation, audits, and management reviews so safety becomes part of daily management, not a separate add-on. It often follows a PDCA cycle—plan, do, check, act—to drive ongoing performance.

The other options miss the common usage: an Incident Safety Management System would focus only on incidents rather than overall safety governance; Integrated Security Management System centers on security rather than safety; and International Safety Management System isn’t the standard term—in shipping you’ll hear International Safety Management Code, which uses Code, not System.
