Human-Caused Emergencies

1. Why Human-Caused Emergencies Matter for the ASP Exam and for Your Career

Most people picture emergencies as hurricanes, floods, or earthquakes. In reality, a large share of the emergencies a safety professional will actually manage are human-caused: a chemical release from a misoperated valve, a fire started by hot work, an angry former employee returning with a weapon, a bomb threat phoned to the front desk, a cyberattack that disables a plant control system, or a structural collapse from an overloaded mezzanine. These events are often sudden, occur with little or no warning, and frequently involve intent or error that natural hazards do not.

For the BCSP Associate Safety Professional (ASP) exam, this topic sits inside the Emergency Preparedness and Response domain. Questions test whether you can: (1) recognize categories of human-caused emergencies, (2) apply the correct regulatory framework (OSHA, EPA, DOT, DHS, NFPA), (3) choose the right protective action (evacuate, shelter-in-place, lockdown, Run-Hide-Fight), (4) understand incident command and training levels, and (5) connect prevention, preparedness, response, and recovery into a complete program. Because emergency questions are scenario-based, understanding the logic behind the standards is far more valuable than memorizing isolated facts.

2. What Is a Human-Caused Emergency?

A human-caused (sometimes called technological or anthropogenic) emergency is any event that threatens life, health, property, operations, or the environment and that originates from human activity, whether intentional or unintentional. Standards such as NFPA 1600 (Standard on Continuity, Emergency, and Crisis Management) and FEMA guidance group hazards into three families: natural, technological (accidental human-caused), and human-caused (intentional). For exam purposes you should be able to sort events into these buckets.

Unintentional (accidental / technological) examples:
- Hazardous material spills and releases (toxic gas, flammable liquid, corrosive)
- Fires and explosions (hot work, dust explosions, electrical faults, process upsets)
- Structural collapse (overloading, poor construction, excavation cave-ins)
- Transportation incidents (tanker rollovers, rail derailments, aircraft crashes)
- Utility failures (power outages, gas line ruptures, water main breaks)
- Equipment or process failures (boiler explosions, pressure vessel ruptures)
- Radiological incidents (lost or damaged industrial gauges, radiography sources)

Intentional examples:
- Workplace violence and active shooter / active assailant events
- Bomb threats, suspicious packages, improvised explosive devices
- Terrorism, including chemical, biological, radiological, nuclear, and explosive (CBRNE) threats
- Sabotage, arson, and vandalism
- Civil disturbances, riots, and protests that turn violent
- Cyberattacks on industrial control systems, access control, or life-safety systems
- Product tampering

Key distinction: Natural hazards cannot be prevented, only mitigated. Many human-caused hazards can be prevented through engineering controls, security, training, and management systems. This is why the exam emphasizes prevention and mitigation so heavily for this topic.

3. The Regulatory and Standards Framework You Must Know

OSHA 29 CFR 1910.38 - Emergency Action Plans (EAP): Required when another OSHA standard calls for one (for example, fire extinguisher, HAZWOPER, or process safety standards). Minimum elements: procedures for reporting emergencies; evacuation procedures, exit route assignments, and type of evacuation; procedures for employees who remain to operate critical operations before evacuating; procedures to account for all employees after evacuation; rescue and medical duties; names or job titles of persons to contact for more information. Must be in writing if more than 10 employees (may be communicated orally for 10 or fewer). Employer must designate and train employees to assist in evacuation and must review the plan with each employee upon initial assignment, when responsibilities change, and when the plan changes.

OSHA 29 CFR 1910.39 - Fire Prevention Plans (FPP): Lists major fire hazards, ignition sources and controls, housekeeping, maintenance of heat-producing equipment, and names/titles of responsible persons.

OSHA 29 CFR 1910.165 - Employee Alarm Systems: Alarms must be distinctive, perceptible above ambient noise and light, and employees must know preferred means of reporting emergencies. Backup alarm means must be available during maintenance.

OSHA 29 CFR 1910.120 - HAZWOPER: Governs emergency response to hazardous substance releases. Five training levels: First Responder Awareness (recognize, notify, take no further action); First Responder Operations (8 hours; defensive actions such as diking and damming from a distance); Hazardous Materials Technician (24 hours; offensive actions, plugging and patching); Hazardous Materials Specialist (24 hours plus specialized knowledge, liaison role); On-Scene Incident Commander (24 hours; assumes control). Requires an Emergency Response Plan, use of the Incident Command System, buddy system, and backup personnel.

OSHA 29 CFR 1910.119 - Process Safety Management (PSM) and EPA 40 CFR Part 68 - Risk Management Program (RMP): Prevent catastrophic releases of highly hazardous chemicals; both require emergency planning and response elements. RMP also requires offsite consequence analysis and coordination with local responders.

EPCRA / SARA Title III (40 CFR 355, 370, 372): Community right-to-know. Facilities with Extremely Hazardous Substances above Threshold Planning Quantities must notify the State Emergency Response Commission (SERC) and Local Emergency Planning Committee (LEPC); releases above Reportable Quantities require immediate notification. CERCLA requires notification to the National Response Center (NRC) for releases above reportable quantities.

OSHA General Duty Clause, Section 5(a)(1): There is no specific OSHA workplace violence standard; OSHA cites employers under the General Duty Clause when a recognized hazard of workplace violence exists and feasible abatement is not implemented. OSHA has published industry guidelines (for example, OSHA 3148 for healthcare and social services; late-night retail guidance).

DOT Emergency Response Guidebook (ERG): Used by first responders in the initial phase of a transportation hazmat incident; provides isolation and protective action distances by UN/NA number. NIOSH Pocket Guide provides IDLH values and exposure limits.

NFPA 1600: All-hazards program standard covering risk assessment, prevention, mitigation, resource management, planning, incident management, training, exercises, and continuity. NFPA 101 (Life Safety Code) governs means of egress. NFPA 1660 now consolidates several emergency management standards.

DHS / FBI Active Shooter guidance: Run, Hide, Fight. The DHS Bomb Threat Checklist guides receptionists and phone operators. FEMA NIMS/ICS provides the command structure for multi-agency response; HSPD-5 established NIMS.

4. How Human-Caused Emergency Management Works: The Four-Phase Model

The exam often frames questions around the four phases of emergency management (sometimes five when prevention is separated from mitigation):

Phase 1 - Prevention and Mitigation: Actions taken before an event to eliminate the hazard or reduce its impact. Examples: inherently safer design (substituting a less toxic chemical, reducing inventory), hot-work permits, lockout/tagout, combustible dust control, secondary containment, physical security (access control, badges, lighting, barriers, visitor management), threat assessment teams, pre-employment screening, cybersecurity segmentation of control networks, structural load ratings, and explosion venting. For workplace violence, mitigation includes zero-tolerance policies, reporting systems, and environmental design (CPTED).

Phase 2 - Preparedness: Building capability to respond. Conduct a Hazard Vulnerability Analysis (HVA) that scores each hazard on probability and severity (human, property, business impact) and preparedness level. Write the EAP, FPP, and (if applicable) HAZWOPER Emergency Response Plan. Establish an Emergency Response Team, define roles using ICS, pre-arrange mutual aid agreements, stock supplies (spill kits, first aid, AEDs, PPE, communication devices), install detection and alarm systems, and conduct training and exercises (orientation seminars, tabletop exercises, drills, functional exercises, full-scale exercises). Coordinate with the LEPC, fire department, law enforcement, and hospitals. Identify assembly areas, primary and secondary exit routes, and shelter-in-place locations. Plan for employees with disabilities (buddy system, areas of refuge).

Phase 3 - Response: Actions during and immediately after the event to protect life, stabilize the incident, and protect property and environment, in that priority order. Core decisions include:
- Evacuate when the hazard is inside or near the building (fire, structural failure, bomb threat with credible device, interior chemical release). Use primary and alternate routes, move upwind and uphill of releases, account for personnel at assembly points.
- Shelter-in-place when the hazard is outside and entering the atmosphere would be more dangerous (exterior toxic gas plume, civil disturbance outside). Close doors and windows, shut down HVAC, seal gaps, move to interior rooms above ground level for heavier-than-air gases.
- Lockdown for an armed intruder or violence threat: secure doors, silence devices, stay out of sight. Run, Hide, Fight empowers individuals to escape if a path exists, hide and barricade if not, and as a last resort act aggressively to incapacitate the attacker.
- Hazmat response: establish hot, warm, and cold zones; isolate and deny entry; identify the material (placards, labels, SDS, shipping papers, ERG); select PPE by level (A, B, C, D) based on respiratory and skin hazards; decontaminate in the warm zone; use the buddy system and standby rescue.
- Bomb threat: keep the caller talking, use the DHS checklist to record exact wording, voice characteristics, and background noise; notify management and police; do not use two-way radios or cell phones near a suspected device; employees (not police) are best suited to identify items that do not belong in their work areas; search and evacuate per the plan.
- Fire: RACE (Rescue, Alarm, Confine, Extinguish/Evacuate) and PASS (Pull, Aim, Squeeze, Sweep) for extinguishers; only trained employees attempt incipient-stage firefighting.
- Incident Command System: single Incident Commander, manageable span of control (3 to 7, optimally 5), unity of command, common terminology, modular organization with Operations, Planning, Logistics, and Finance/Administration sections; Unified Command when multiple agencies have jurisdiction.
- Notifications: OSHA within 8 hours for a fatality, 24 hours for in-patient hospitalization, amputation, or loss of an eye; NRC immediately for CERCLA reportable quantity releases; LEPC and SERC for EPCRA releases; local 911.

Phase 4 - Recovery: Restoring operations and learning. Includes accounting for all personnel, medical follow-up, critical incident stress management and employee assistance programs (especially after violence), scene preservation for investigation, damage assessment, salvage and cleanup, business continuity and restoration of utilities, communication with employees, families, media, and regulators, and a formal post-incident review or after-action report feeding corrective actions back into mitigation. Root cause analysis (for example, using the Chemical Safety Board approach for process incidents) closes the loop.

5. Deep Dive: Workplace Violence Categories

You must know the four types of workplace violence used by NIOSH, OSHA, and the FBI:
- Type I - Criminal Intent: Perpetrator has no legitimate relationship to the business; violence occurs during a crime such as robbery. Highest-risk groups: taxi drivers, late-night retail, cash-handling workers. Controls: cash control, visibility, lighting, security cameras, bullet-resistant barriers.
- Type II - Customer/Client: Perpetrator is a customer, patient, student, or inmate. Most common in healthcare and social services. Controls: staffing, alarm systems, de-escalation training, secure treatment areas.
- Type III - Worker-on-Worker: Current or former employee attacks coworkers or supervisors. Controls: threat assessment teams, discipline and termination procedures, access revocation, reporting culture.
- Type IV - Personal Relationship: Perpetrator has a relationship with an employee (domestic violence spilling into the workplace). Controls: restraining order policies, photo distribution to security, safety planning with the affected employee.

Exam questions often describe a scenario and ask which type it represents, or ask for the most effective control for that type.

6. Deep Dive: Hazardous Material Release Fundamentals

- Recognition and identification: NFPA 704 diamond (blue health, red flammability, yellow instability, white special), DOT placards and hazard classes 1 through 9, GHS labels and SDS Section 4 (first aid), Section 5 (firefighting), Section 6 (accidental release).
- Vapor density: Greater than 1 means heavier than air and settles in low areas; less than 1 rises. Determines shelter location and ventilation strategy.
- Protective action distances: From the ERG green pages; larger for night, large spills, and water-reactive materials.
- PPE levels: Level A (fully encapsulating suit with SCBA, highest respiratory and skin protection); Level B (SCBA with chemical-resistant clothing, highest respiratory but less skin protection); Level C (air-purifying respirator, known contaminant with adequate oxygen and concentration below IDLH); Level D (work uniform, no respiratory hazard).
- Zones: Hot (exclusion), Warm (contamination reduction/decon corridor), Cold (support).

7. Exam Tips: Answering Questions on Human-Caused Emergencies

Tip 1 - Apply the life-safety hierarchy. When a scenario asks what to do first, the order is almost always: protect life (alert and evacuate or shelter people), then notify responders, then stabilize the incident, then protect property and environment. Any answer that puts property or production ahead of people is wrong.

Tip 2 - Decide: evacuate, shelter, or lockdown. Hazard inside or structural threat = evacuate. Toxic hazard outside = shelter-in-place and shut off HVAC. Armed threat = Run, Hide, Fight / lockdown. Watch for distractors that suggest evacuating directly into a chemical plume or using elevators during a fire.

Tip 3 - Know the HAZWOPER levels by action. Awareness = recognize and notify only. Operations = defensive, from a distance (dike, dam, divert). Technician = offensive, stop the release. Specialist = technical expert and liaison. Incident Commander = overall control. If a question says an employee should take defensive action only, the answer is Operations level.

Tip 4 - Memorize EAP minimum elements and the 10-employee rule. Questions frequently ask which element is not required by 1910.38 or when a plan may be oral. Rescue and medical duties, accounting for employees, and critical-operations shutdown procedures are required; fire extinguisher inventories and insurance information are not.

Tip 5 - Workplace violence has no specific OSHA standard. The correct regulatory answer is the General Duty Clause 5(a)(1). Also be ready to classify Types I through IV from a scenario description.

Tip 6 - Bomb threats favor employee searches and radio silence. Employees know what belongs in their area, so they assist in searching. Do not touch suspicious items. Avoid transmitting on radios near a device. Keep the caller on the line and complete the checklist.

Tip 7 - Use ICS vocabulary correctly. Span of control 3 to 7, one Incident Commander, Unified Command for multi-jurisdiction events, Command Staff (Safety Officer, Public Information Officer, Liaison Officer) versus General Staff (Operations, Planning, Logistics, Finance/Administration). The Safety Officer has authority to stop unsafe acts.

Tip 8 - Know reporting clocks. OSHA: 8 hours for fatality, 24 hours for hospitalization, amputation, eye loss. CERCLA/EPCRA: immediate notification to NRC, SERC, and LEPC for releases above reportable quantities. Written follow-up for EPCRA Section 304 releases.

Tip 9 - Link the four phases. If a question asks where a hot-work permit, access control, or inherently safer design belongs, the answer is mitigation/prevention. Drills, HVA, and mutual aid agreements belong to preparedness. After-action reviews and counseling belong to recovery.

Tip 10 - Choose the most comprehensive, systematic answer. BCSP questions reward management-system thinking: risk assessment first, written plan, training, exercises, evaluation, and continuous improvement. When two answers seem plausible, pick the one that is proactive, addresses root causes, and is supported by a recognized standard rather than the one that is reactive or relies on a single control.

Tip 11 - Watch qualifiers. Words like first, most important, minimum, best, and not required change the correct answer. Read the stem twice and eliminate answers that are true statements but do not answer the specific question.

Tip 12 - Practice with scenarios. Create flashcards that pair a short scenario (for example, a chlorine cylinder leaking at the loading dock on a calm night) with the correct protective action, PPE level, training level needed, notification requirements, and ICS role. This mirrors how the ASP exam tests this topic.
