A job-safety-analysis (JSA) is a human-made structured hazard-identification procedure that breaks a work task into discrete sequential steps, examines each step for potential hazards, and prescribes controls before the work begins. Its parameters are: (1) step-by-step decomposition of a specific job, (2) hazard identification per step (mechanical, chemical, ergonomic, environmental), and (3) control prescription — elimination, engineering controls, administrative controls, or PPE — in order of hierarchy. It persists through standardized checklists, documented procedures, and recurrent training that embed the practice in organizational routines. The procedure is operational at the moment of task initiation: if the JSA is removed, the organized pre-task hazard review stops operating entirely, even though workers may still perform the job unsafely by habit or expediency.

Definition
Why it is in scope
Human-made procedural practice of breaking down individual work tasks into steps, identifying hazards at each step, and specifying controls to eliminate or mitigate those hazards. Built to persist through training programs, checklists, and standardized worksheets used in occupational health and safety management.

Job-safety-analysis is a structured hazard-identification technique designed and maintained for the sake of safety-management-system. It provides the systematic pre-task hazard assessment that SMS requires to function as an integrated safety framework. Law 8d: the servant (JSA) points at the master (SMS).

Law 9: job-safety-analysis is a specific kind of hazard-assessment. JSA is a structured method where a worker systematically breaks down a job into steps and identifies hazards at each step. It is one particular methodology under the broader class of hazard-assessment techniques.

Job-safety-analysis is a task-level hazard identification method designed and maintained within safety-management's framework. Its purpose is to feed structured hazard data into safety-management's cycle. SERVES: the method (JSA) points at the system it serves (safety-management).
