Security Guard Group Limited
Answer from SECURITY GUARD GROUP LIMITED
Security Guard Group prepares guards through a combination of mandatory training, site-specific orientation, and practical emergency-response procedures. Guards are trained in First Aid/CPR, emergency communications, incident reporting, de-escalation, fire and medical emergency response, evacuation procedures, and contacting emergency services. Before assignment, guards review the property's post orders, emergency contacts, evacuation procedures, and site-specific hazards. Additional training may be required depending on the assignment, including crisis intervention, mental health awareness, use of force, vulnerable-person interaction, or construction-site safety. Guards are also trained to assess situations before intervening, protect life first, request appropriate emergency resources, and maintain communication with our 24/7 Dispatch team.
