Final answer:
The proper order of basic questioning techniques used by a PST to classify a call is summarized by option B: 'What, Where, When, Who, How, Weapons', to ascertain the nature, location, timing, individuals involved, sequence of events, and any immediate danger presented by weapons.
Step-by-step explanation:
The basic questioning techniques used by the Public Safety Telecommunicator (PST) to properly classify a call involve a series of targeted questions that can quickly provide critical information about an incident. The correct order in which to ask these questions is summarized by option B: 'What, Where, When, Who, How, Weapons.'
This sequence starts with 'What' to understand the nature of the incident. Next, 'Where' helps to pinpoint the location, followed by 'When' to establish the timing of the situation. Identifying 'Who' is involved provides information on subjects or victims. 'How' helps to understand the sequence of events or the method of any crime or situation. Finally, 'Weapons' is asked to assess any immediate danger to those involved or to responding personnel. This order is important to ensure that the most crucial information is obtained efficiently and effectively so that the appropriate response is dispatched.
