Scenario: Industrial Security During Plant Expansion – Integration of External Security Forces
A mid-sized chemical company is expanding its production site with a large new facility. The construction work will span 18 months and involves multiple trades. The existing plant remains in full operation throughout the entire construction phase. The company’s in-house security department is already fully occupied with monitoring ongoing operations and cannot handle the additional construction site surveillance. Our company is brought in as an external security service provider.
The special challenge: The plant is subject to strict legal regulations (including operational safety, hazardous substances, and explosion protection regulations). External security personnel must not only be integrated into the general security procedures but also trained in the specific hazardous materials, emergency plans, and access regulations of the chemical industry.
Phase 1: Preparation and Integration (Before Construction Begins)
1. Needs Assessment and Contractual Arrangements
- Joint site inspection with plant security and the construction management team.
- Identification of security-relevant areas:
- Existing Plant: Ongoing operations with hazardous materials, reactors, storage tanks
- Construction Site: Several construction phases with heavy equipment, structural and civil engineering
- Interfaces: Utility lines, truck access roads, transitions between construction and operational areas
- Definition of deployment schedules: 24/7 operations with three shifts, as construction runs around the clock.
- Establishment of required qualifications:
- Security Personnel: Must be certified according to local regulations (e.g., § 34a GewO or equivalent)
- Additional: Training in chemical safety, hazardous materials handling, explosion protection (Ex-zones)
- Fire Protection Knowledge: Fire extinguisher handling, evacuation plans
2. Training and Instruction Program for External Security Personnel
- General Plant Security Induction (1 day):
- Plant premises, access roads, emergency exits
- Behavior in case of incidents (alarm activation, evacuation, assembly points)
- Company safety culture
- Specific Hazardous Materials Instruction (2 days):
- Chemical handling (safety data sheets, GHS labeling)
- Hazardous areas and Ex-zones (zone classification 0, 1, 2)
- Detection of leaks, vapors, unusual odors
- Measures for minor releases (e.g., containment, reporting)
- Construction Site Safety Instruction (1 day):
- Specific construction site hazards (crane operations, civil engineering, working at height)
- Access regulations for construction workers and subcontractors
- Monitoring of construction vehicles (entry and exit)
- Emergency Training (1 day):
- Practical exercises: fire extinguisher handling, evacuation from Ex-zones
- Emergency communication: radio discipline, alarm chain
- First aid with focus on chemical incidents (eye wash, contamination)
3. On-the-Job Training
- Accompanied shifts for the first two weeks: An experienced plant security officer works alongside each new external employee.
- Practical instruction in:
- Electronic access systems (chip cards, PIN, biometric methods)
- Video surveillance systems and their operation
- Incident and alarm reporting systems
- Establishment of a “buddy system”: Each external employee is paired with an experienced plant employee.
Phase 2: Daily Operations – Integration into the Security Network
1. Division of Responsibilities Between Plant Security and External Forces
| Task Area | Plant Security (Internal) | External Security Personnel |
|---|---|---|
| Monitoring of existing plant | Primary responsibility | Support with access control |
| Construction site surveillance | Coordination | Primary responsibility for construction area |
| Employee access control | Responsible | Assistance during shift changes |
| Construction worker access control | Approval by plant security | Execution on-site |
| Emergency management | Leadership and decision-making | Support and implementation |
| Monitoring of hazardous areas | Technical responsibility | Reporting of irregularities |
| Documentation | Overall overview | Daily reports to plant security |
2. Daily Security Patrols
- Joint Morning Briefing (07:00):
- Exchange between plant security, external security service, and construction management
- Discussion of current construction progress and special risks of the day
- Coordination of shift handovers
- Three Shifts with Fixed Responsibilities:
- Morning Shift (06:00–14:00): Main burden of visitor and delivery traffic management
- Afternoon Shift (14:00–22:00): Focus on construction progress and material deliveries
- Night Shift (22:00–06:00): Surveillance in darkness, security of construction equipment
- Controlled Patrols:
- At least hourly through the construction area
- Every two hours through the existing plant (together with plant security)
- Checking: fences, gates, lighting, locking of hazardous areas
3. Access Management for the Construction Site
- Multi-Level System for Construction Workers:
- Level 1 – Registration: Each construction worker is registered in the system before starting work (ID card, social security verification)
- Level 2 – Instruction: Proof of construction site safety instruction (according to local regulations)
- Level 3 – Access Authorization: Issuance of a personalized construction badge with QR code and photo
- Level 4 – Area Clearance: Only authorized for specific construction sections (e.g., no access to chemical storage areas)
- Daily Checks:
- Random identity checks by external security personnel
- Cross-reference with the construction management’s daily list
- In case of discrepancies: Immediate notification to plant security and construction management
Phase 3: Handling Special Hazards in the Chemical Industry
1. Detection and Reporting of Hazardous Materials
- External security personnel are trained to immediately recognize and report the following signs:
- Unusual odors: Solvents, sulfur, gas
- Visible vapors or mist: Leaking from pipelines or containers
- Escaping liquids: Puddles, trickles, discoloration
- Damaged containers: Leaking drums, torn film wrapping
- Reporting Chain:
- Step 1: External security officer detects anomaly
- Step 2: Immediate report to plant security (via radio or emergency call)
- Step 3: Plant security decides on further measures (containment, evacuation, fire department/environmental agency)
- Step 4: External forces secure the area and initiate initial measures if necessary (e.g., moving people out of danger zone)
2. Handling Ex-Zones (Explosion Protection)
- The plant has defined Ex-zones where explosive atmospheres may occur.
- Rules for External Security Personnel:
- Only use approved, explosion-proof equipment (e.g., certified flashlights, radios)
- No ignition sources: smoking, fire, sparks prohibited
- Access only after approval by plant security with special instruction
- In case of release of flammable gases or vapors: immediate evacuation and alert
- Labeling: Ex-zones are clearly marked with floor markings and signs – external personnel learn these markings during instruction.
3. Handling Construction Work in Hazardous Areas
- Hot Work (welding, cutting, soldering):
- Requires a special permit (“hot work permit”) from plant security
- External security personnel monitor that this permit exists and that fire protection measures (fire extinguishers, fire blankets, fire watch) are in place
- Civil Engineering Work (earthworks, pipeline work):
- Hazard: Damage to underground chemical pipelines
- External security personnel check whether “excavation clearance” (approval from plant security) has been obtained before work begins
- If unexpected finds occur (pipes, cables), work is stopped immediately and plant security is alerted
Phase 4: Emergency Management and Crisis Intervention
1. Emergency Scenarios in the Chemical Industry
| Scenario | Measures |
|---|---|
| Chemical Incident (Release of Hazardous Materials) | Area containment, evacuation, alert plant security and fire department, keep breathing protection ready |
| Fire in Existing Plant | Initiate fire protection plan, firefighting by plant fire brigade (or external personnel with appropriate training), evacuate construction site, block access points |
| Explosion Hazard | Immediate alert of all persons, complete evacuation of hazard zone, containment of extended security radius, alert fire department and police |
| Accident on Construction Site (Personal Injury) | First aid by trained personnel, alert emergency services, contain accident site, documentation for regulatory authorities |
| Attack or Sabotage | Trigger silent alarm, lock all access points, notify police, bring persons in building to safety |
2. Coordination Between External Forces and Plant Security
- Crisis Committee: For major incidents, a joint crisis committee comprising plant management, the safety officer, and the external security service convenes.
- Communication: External forces are integrated into plant communication via radio and receive all relevant information simultaneously.
- Debriefing: After an emergency, a joint debriefing with analysis, documentation, and possible adjustment of security measures takes place.
3. Regular Emergency Drills
- Quarterly Drills involving all external security personnel:
- Fire Drill: Extinguishing a controlled fire, evacuation from Ex-zone
- Chemical Incident Drill: Containment, alerting, person search
- Active Shooter or Sabotage Drill: Lockdown, police alert, search
- The drills are led by plant security and carried out with external forces participating.
Phase 5: Documentation and Reporting
1. Daily Reporting
- External security personnel prepare a daily digital report including:
- Number of access events (employees, visitors, construction workers, suppliers)
- Special incidents (alarms, disturbances, irregularities)
- Condition of security equipment (fences, gates, lighting, cameras)
- Deviations from safety regulations (e.g., open doors, missing permits)
- The report is transmitted to plant security and incorporated into the overall documentation.
2. Weekly Report for Management
- Summary of security-relevant events of the week
- Presentation of clusters or patterns (e.g., increased fire safety violations)
- Recommendations for improvements (e.g., additional training, adjustment of access regulations)
3. Final Report at Project Conclusion
- Upon completion of the construction measure, the external security service prepares a comprehensive final report including:
- Overall overview of all security measures during the construction phase
- Statistics on accesses, alarms, and incidents
- Lessons learned – which measures proved effective, what could be improved?
- Handover of documented security data to plant security for future projects
Phase 6: Special Challenges and Solutions
1. Language Barriers and International Teams
- The construction site is staffed by an international subcontractor network.
- Solution: External security personnel receive multilingual safety instructions (German, English, Polish, Turkish).
- Access control points are equipped with pictograms and multilingual signage.
2. High Delivery Traffic
- Up to 50 trucks daily with construction materials, chemicals for operations, and waste transport.
- Solution: Establishment of a separate supplier access with its own security post.
- Time scheduling: Deliveries are staggered in time slots (e.g., 06:00–08:00, 12:00–14:00, 18:00–20:00) to avoid overload.
3. Changing Construction Phases
- The construction site grows over time – new areas are opened, others are completed.
- Solution: Weekly update of the security zone map by construction management.
- External security forces are immediately informed of new hazardous areas and access routes in a short briefing (15 minutes) upon each change.
4. Shift Models and Fatigue
- Construction work runs around the clock with three shifts.
- Solution: External security personnel are deployed in a balanced shift model (max. 8 hours per shift, minimum 11 hours rest).
- Regular health checks and an open reporting system for overload situations.
Conclusion: Success Factors for Collaboration
The integration of external security forces into an existing chemical company is a demanding task. The success of the scenario is based on five central pillars:
| Pillar | Description |
|---|---|
| 1. Thorough Induction | Comprehensive training in chemical safety, hazardous materials, Ex-zones, and construction site safety |
| 2. Clear Responsibilities | Separation of existing plant surveillance and construction site surveillance with designated contacts |
| 3. Continuous Communication | Daily meetings, joint patrols, open reporting culture |
| 4. Practical Drills | Regular emergency drills involving all participants |
| 5. Documentation and Follow-up | Complete recording of incidents and measures for post-incident review |
Through this structured approach, it is ensured that the expansion of the chemical plant can be realized safely, in compliance with regulations, and without disruption to ongoing operations.
