社区应急反应队(CERT)

CERT trains civilians to help their communities after earthquakes. Learn how to join, what training involves, and why CERT matters.

What Is a Community Emergency Response Team?

Community Emergency Response Teams — universally known as CERT — represent one of the most practical expressions of citizen disaster preparedness. CERT is a training program that prepares community members to assist neighbors and neighborhoods in the immediate aftermath of a disaster. Developed originally in Los Angeles after the 1971 Sylmar earthquake and the 1994 Northridge earthquake, the program has since spread to thousands of communities across the United States and has been adopted in various forms internationally.

The core insight behind CERT is that professional emergency services — however well-resourced and trained — simply cannot reach every person simultaneously in a major disaster. A single major earthquake can generate thousands of simultaneous emergencies across an entire metropolitan area. By training ordinary citizens to handle manageable emergencies independently and to support professional responders intelligently, CERT multiplies the effective emergency response capacity of communities significantly.

CERT Training Curriculum

Standard CERT training consists of approximately 20 hours of instruction covering seven functional areas. The curriculum is designed to be completed over several evenings or a weekend, making it accessible to working adults.

[[Disaster-preparedness]] education forms the foundation: participants learn about hazards specific to their region, how disaster systems work, and the role of individual and community preparedness. This section explicitly addresses the limitations of professional response capacity during catastrophic events, preparing trainees for a realistic picture of what they will and will not receive from authorities in the first hours.

Fire safety training covers how to use fire extinguishers for small fires, when to fight and when to evacuate, and how to shut off gas. Utility control is emphasized because ruptured gas lines are a major 次生地震灾害由地震震动引发而非震动本身直接造成的灾害,包括海啸、滑坡、液化、火灾、水坝溃决及化学品泄漏等,其造成的损失往往超过震动本身。 risk after earthquakes. Basic medical operations cover bleeding control, shock management, airway assessment, and improvised stretcher construction. The CERT triage system — a simplified version of professional mass casualty triage — teaches trainees to rapidly categorize survivors into immediate, delayed, and expectant categories based on a brief assessment, maximizing the number of people who receive appropriate care.

Light search and rescue training teaches participants how to assess structural stability of damaged buildings, how to work as a team to move debris, and how to communicate with trapped survivors. This training specifically addresses the boundaries of safe volunteer operations and when to stop and wait for professional rescue teams.

How CERT Teams Activate

CERT activation depends on local procedures, but generally follows two pathways. In a major disaster, local emergency management agencies activate organized CERT teams through pre-established communication trees — phone, text message, or emergency alert systems. Trained CERT members report to their designated staging area, receive a mission briefing, and deploy as organized teams under local emergency management direction.

The second pathway is spontaneous: trained CERT members who are present in an affected area begin applying their skills immediately, working within the scope of their training without waiting for official activation. This spontaneous response is often the most valuable, because CERT members present in an affected neighborhood can begin 搜救(SAR)地震后有组织地开展定位并救出被困于倒塌建筑物中幸存者的行动。震后头72小时是发现生还者的关键窗口期。 operations in the critical first hour when professional responders have not yet arrived.

Integration with Professional Responders

One of the most important things CERT teams are taught is how to work effectively alongside professional emergency services. CERT members do not freelance or operate independently of the incident command structure once professional responders arrive. They report in, identify their training and capabilities, accept assigned missions, and operate within the chain of command. This discipline is critical because uncoordinated volunteers can impede professional operations, consume professional attention managing them, and create additional casualties.

CERT teams are most effective for supporting operations — establishing and managing survivor collection points, providing medical assessment and first aid at staging areas, conducting organized searches of lightly damaged structures, managing traffic and crowd control, and supporting logistics operations — rather than direct technical rescue in heavily collapsed structures.

The Community Resilience Argument

Research on disaster outcomes consistently shows that community social cohesion is one of the strongest predictors of recovery quality. Communities where neighbors know each other, where there is organized local capability, and where people have been trained to help one another consistently suffer fewer deaths and recover more rapidly from comparable disasters than socially fragmented communities with identical physical vulnerabilities.

CERT training contributes to this cohesion in multiple ways. The training itself brings neighbors together and creates relationships before a disaster strikes. CERT exercises and meetings maintain these relationships and reinforce preparedness habits. And during a disaster, CERT members serve as trusted local figures who can communicate accurately, reduce panic, and direct community effort productively.

[[Disaster-preparedness]] at the household level is powerfully reinforced by CERT membership. CERT members are significantly more likely to have personal emergency kits, household emergency plans, and utility shutoff tools than the general public. The training creates a virtuous cycle of preparedness.

Limitations and Criticisms of CERT

CERT has legitimate limitations that its advocates should acknowledge honestly. Training quality varies enormously between programs; a well-resourced program with active exercise schedules produces genuinely capable responders, while a poorly maintained program may produce trainees whose skills have degraded significantly since initial training. Retention is a perennial challenge: CERT membership requires ongoing time commitment that many people cannot sustain.

The scope limitations of CERT are also real. CERT members are explicitly trained not to enter heavily damaged structures, attempt technical rope rescues, operate in hazardous materials environments, or conduct advanced medical procedures. These boundaries are essential for volunteer safety, but they mean that CERT cannot substitute for professional capacity in complex rescue scenarios. In some historical disasters, well-intentioned volunteers — some CERT members, many untrained — have entered dangerous structures and become casualties themselves, creating additional rescue demands.

The best CERT programs acknowledge these boundaries explicitly, conduct regular exercises to maintain skills, and invest in ongoing relationships with professional emergency services so that integration is practiced before it is needed.

Building a CERT Program

Communities interested in establishing CERT programs can contact their local emergency management agency, which in the United States can connect them with FEMA's CERT Program. Initial training materials are provided, and train-the-trainer programs allow communities to build local instructional capacity. The most successful programs are institutionally supported — by municipalities, large employers, neighborhood associations, or faith communities — because institutional support provides the meeting space, communication infrastructure, and organizational continuity that volunteer programs require to survive over years.

In earthquake-prone regions, the case for CERT investment is particularly compelling.

地震准备的关键步骤:将重型家具和热水器固定在墙上;准备含有水、食物、手电筒、收音机和急救用品的应急包,至少够用3天以上;确定每个房间的安全位置(坚固桌子下方、远离窗户);练习“蹲下、掩护、抓紧”演练;了解如何关闭燃气和水阀。

如果在室内:蹲下、掩护、抓紧——双膝跪地,躲在坚固的桌子下面,紧紧抓住直到震动停止。不要跑到室外或站在门口。如果在室外:移到远离建筑物、电线和树木的开阔地带。如果在开车:靠边停车,留在车内。

地震保险承保地震对建筑物和财物造成的损害,而标准的房屋保险通常不包含此项。是否需要取决于所在地区的地震风险、建筑结构类型以及承受地震损失的经济能力。在加利福尼亚和日本等高风险地区,强烈建议购买地震保险。
