BS ISO 22341:2021 pdf free download – Security and resilience一Protective security一Guidelines for crime prevention through environmental design.
The organization should require the oversight body to provide evidence of its commitment to security
and crime prevention/reduction by CPTED by:
— communicating and disseminating the importance of meeting security requirements;
— establishing a security policy;
— conducting a risk assessment in existing or proposed new environments;
— ensuring that general security objectives relate to the relevant rules if they are established;
— defining the areas that are subject to the procedure of this document;
— providing a technical support for security policy;
— ensuring the availability of resources.
The organization should:
— set up a technical structure to support the security policy and crime prevention policy;
— assign to top management the responsibility for starting a process aimed at meeting the security objectives as formulated by the oversight body;
— request the oversight body to appoint a person who, irrespective of other responsibilities, has the responsibility for and authority over:
— ensuring that the necessary steps in the process are established, implemented and maintained;
— reporting on the process to other members of the oversight body.
The organization should require that the oversight body confirm that the following four preliminary questions have been answered:
— the exact identification of the area under consideration (where);
— the general identification of the crime problems that can, will or seem to take place in this area (what);
— interested parties (who);
— site surveys (visual audit) showing the detailed physical security features of an area;
— spatial analysis software or computational tools that measure the degree of accessibility and surveillance quantitatively for specific risk related to a Street segment within a city Street network.
The organization should consider developing a checklist for risk assessment.
The organization should consider scoring the likelihood of occurrence with standard linear scaling. In order to provide a better stratification of risk levels, the organization should consider using a modified or weighted scaling system.
The organization should consider scoring severity of consequences with standard linear scaling. In order to provide a better stratification of risk levels, the organization should consider using a modified or weighted scaling system.
NOTE IEC 31010 provides a range of qualitative and quantitative risk assessment techniques that include details on the process of planning, implementing, verifying and validating the use of the assessment techniques.
For the risk evaluation process, the organization should:
— compare the estimated levels of crime and security risk with the risk criteria defined when the context was established;
— use the understanding of the risk obtained in the risk analysis to make decisions about the strategies required for risk control and treatment;
— systematically assess risk to apply CPTED-related risk treatments appropriate to the activities planned for the spaces;
— direct the project team to identify, analyse and evaluate the risk of a target area or site, and to select and define the specific CPTED strategies and measures for the implementation of the CPTED project based upon the result of the risk assessment and in accordance with the performance target statement;
— determine the scaLingand assignment of riskievels that best suits its priorities and available resources;
— provide the outcome of risk assessment to CPTED interested parties as information for decisionmaking about the priorities and choices of CPTED strategies;
— discuss the outcome of the risk assessment with the oversight body.
