✓
Answer
(i) Mock drill is a practice to check preparedness of facing the disaster as early as possible.
(ii) It helps in evaluating the response to the disaster.
(iii) Virtual or apparent situations of disaster are created to check the reaction time for any types of disaster.
(iv) Trained personnel observe their responsibilities to check execution of plan designed for the disaster rehearsal.
(v) Mock drill helps to check the competency of planned actions and identifying the possible errors and risks.
(vi) Mock drill includes demonstrations like extinguishing the fire, rescuing the people trapped at higher floors of the building, rescuing the persons whose clothing have caught fire etc.
(vii) Hence mock drills is useful.
