NIMS is a systematic, proactive approach to guide departments and agencies at all levels of government, nongovernmental organizations (NGO), and the private sector in working together seamlessly and managing incidents involving all threats and hazards—regardless of cause, size, location, or complexity—in order to reduce loss of life, loss of property, and harm to the environment. NIMS is the essential foundation to the National Preparedness System and provides the template for the management of incidents and operations in support of all five National Planning Frameworks.
ICS is a standardized on-scene incident management concept designed specifically to allow responders to adopt an integrated organizational structure equal to the complexity and demands of any single incident or multiple incidents without being hindered by jurisdictional boundaries.
A Job Hazard Analysis is a technique that focuses on job tasks as a way to identify hazards before they occur. It focuses on the relationship between the worker, the task, the tools, and the work environment. Ideally, after you identify uncontrolled hazards, you will take steps to eliminate or reduce them to an acceptable risk level.
