Which of the following actions is NOT advised when handling suspicious packages?

Opening the package immediately is not advised when handling suspicious packages because it poses significant risks to personal safety and public security. Upon encountering a suspicious package, the primary concern should be to avoid potential hazards, including exposure to harmful substances or devices.

Isolating the package helps to minimize the risk to others and allows responders to assess the situation without further endangering the public. Alerting security ensures that trained professionals take appropriate action in line with established protocols, and evacuating the area can help safeguard individuals from any potential threats associated with the suspicious package. Thus, the immediate opening of the package contradicts safety practices and emergency response protocols.
