PRACTITIONERS: these are Law Enforcement Agencies (LEAs; typically Police organisations), First Responders (e.g. civil protection agencies, fire brigades, ambulance) and related stakeholders including private and public bodies, transport and logistic operators, etc. who may be involved in a response in support of the official responders and international, national and municipal authorities and civil society organisations such as those that help persons with disabilities and crisis management. (From the latter perspective, ‘Practitioner’ may also include personnel who were not specifically trained for CBRNe response or CBRN decontamination procedures, such as railway staff at a railway station or a doctor who might be caught up in the incident).

CITIZENS: these are members of the public but specifically including citizens with needs that differ to the average population such as persons with disabilities, the ill (e.g. with chronic or acute health conditions), elderly, or members of an ethnic minority or of a vulnerable group. Vulnerable groups may include  children, pregnant women, persons with disabilities, chronic medical disorders or addiction, older persons with functional limitations and health restrictions, institutionalized individuals as well as their carers and companions. Vulnearable citizens also include persons with limited proficiency of the respective national languages or with restrictions regarding use of transportation.

TOOLS: these include processes, software, procedures, machine, mechanism, apparatus, appliance, piece of equipment and contraption.  Several tools can be regrouped under a toolkit dedicated to a specific target group.
