Local warning systems are installed at facilities that pose a high risk to the population (hydroelectric power plants and nuclear plants, chemical and defense enterprises). With their assistance, the emergency is made aware not only of the service personnel but also of the residents of the areas that may be affected by the danger. When an emergency occurs, the duty dispatcher or other responsible person turns on sirens whose signal means “Attention all”, then a voice instruction is transmitted defining order of action of citizens.
SMS messages, messages on urban forums on the Internet, running line and news blocks on TV, ads on the radio are used for emergency alerts. These ways can hardly be called effective — people don’t watch TV round the clock and don’t read texts at night. The traditional method – cars equipped with hands-free communication – is much more reliable.
An alert system will only be effective if citizens are firmly aware of how to proceed after the alarm is sounded. In any ZhEU there has to be a stand on which the order of actions of citizens in an emergency situation is described. Learn this instruction. Find out where the shelter your house is attached to. Check to see if your home has a first aid kit stocked with first aid.
