What is the key difference between an 'incident' and an 'accident' in modern safety management terminology?

A construction supervisor notices a worker wearing a hard hat that has been painted. What is the safety concern?
Answer: Paint solvents can degrade the shell material and reduce impact protection

Answer: To identify task-specific hazards and agree on controls before work begins
Pre-task planning brings workers and supervisors together before starting work to identify hazards specific to that task and establish agreed-upon controls.
