Planning for defence against nuclear, biological and chemical attack on the Undertaking does not fall within the standard scope of technical consultancy services provided by the CISF.
CISF’s technical consultancy services primarily focus on providing expertise in industrial security, fire protection, and disaster management for critical infrastructure and industrial undertakings. These services aim at assessing security vulnerabilities, suggesting mitigation measures, and preparing for various emergencies within the typical threats faced by such establishments.
CISF’s consultancy wing offers services like security surveys, risk assessment, planning and designing integrated security systems (physical, electronic, access control), fire safety audits, fire fighting system design, communication network planning, and comprehensive disaster management planning. Defence against specialized threats like nuclear, biological, or chemical (NBC) attacks requires highly specialized expertise and is typically handled by dedicated national agencies like the National Disaster Response Force (NDRF) for response, or specialized wings within defense/security establishments for prevention and mitigation strategies. While CISF is involved in overall disaster management plans, the technical consultancy scope generally does not extend to the specific, highly complex domain of NBC attack defence planning.
