School Shelter-in-Place Drill (HAZMAT): A Guide

hazmat incident

Shelter-in-place drills are essential components of school safety programs, preparing students and staff for situations where staying inside the school building is the safest course of action.

One primary reason for these drills is to prepare for hazardous materials (hazmat) incidents, such as chemical spills or airborne toxic events.

Conducting these drills regularly helps ensure everyone understands the proper procedures to follow in case of real emergencies and reduces panic or confusion.

In Texas, for example, schools are required to conduct two shelter drills per year: one for shelter-in-place for hazmat situations and another for severe weather conditions.

These drills involve standardized, specific actions for all school staff and students, including relocation to specific areas in the building and practicing additional protective measures depending on the type of threat.

Schools need to coordinate with local authorities and emergency responders to ensure that their shelter-in-place plans are consistent with community-wide strategies regarding hazmat incidents.

This collaboration can help increase overall preparedness and facilitate efficient communication during a real event, allowing for a more effective response and quicker return to normal operations post-incident.

Overall, shelter-in-place drills play a critical role in maintaining the safety and well-being of students and staff during hazmat emergencies.

Understanding a School Shelter-in-Place Drill Hazmat

Shelter-in-Place Basics

Shelter-in-place drills are designed to protect students, staff, and visitors from potential hazards or threats such as hazardous materials (hazmat) incidents.

During a shelter-in-place drill, the school activates its emergency plan, and everyone inside the building is directed to designated safe areas.

The goal is to minimize exposure to the hazard and ensure everyone’s safety until the threat has passed or authorities have given the all-clear signal.

Hazmat Threats and Hazards

Hazmat incidents can occur due to various factors, such as chemical spills, gas leaks, or even acts of terrorism.

These incidents have the potential to cause severe health issues, property damage, and environmental harm.

Schools must have plans in place to address the specific needs and actions required to adequately protect their occupants during a hazmat-related shelter-in-place event.

This includes identifying safe rooms, establishing communication methods, and having a list of necessary supplies to sustain the individuals inside the shelter.

Difference Between Lockdown, Evacuation, and Shelter-in-Place Drills

Understanding the differences between lockdown, evacuation, and shelter-in-place drills is critical for effective emergency management in schools:


Lockdown drills are implemented when there is an immediate threat inside the school, such as an intruder or active shooter. Everyone is directed to lock doors, turn off lights, and remain silent and out of sight until the situation is resolved.


Evacuation drills involve the orderly exit of all building occupants in the event of fires, bomb threats, or other incidents that make staying inside the building unsafe. Students and staff follow predetermined routes to safety zones or assembly points outside the school.


Shelter-in-Place drills are implemented when there is a hazard or threat outside the school, such as hazardous materials or severe weather. The building is secured, and individuals are directed to safe areas within the school.

As we mentioned above, a school shelter-in-place drill for hazmat situations is focused on protecting students and staff from external hazards by keeping them in designated safe areas within the school.

Preparation and understanding of the differences between lockdown, evacuation, and shelter-in-place drills are crucial for ensuring the safety and well-being of everyone in the school community during emergencies.

Implementing Shelter-in-Place Hazmat Drills

Collaboration with Local Authorities and Emergency Management

It is essential to collaborate with local authorities and emergency management agencies when planning and implementing shelter-in-place hazmat drills in schools.

These agencies can provide expertise in handling hazardous materials incidents, understanding the Incident Command System (ICS), and implementing the Standard Response Protocol (SRP).

By working together, schools and emergency management professionals can develop effective precautions and response plans to ensure enhanced safety and protection during hazmat events.

Developing the Shelter-in-Place Annex

A crucial aspect of implementing shelter-in-place hazmat drills is the development of a comprehensive Shelter-in-Place Annex for the school’s emergency response plan.

This annex should include:

  • Clearly defined roles and responsibilities for administrators, staff, and students.
  • Identification of safe locations within the school for sheltering during a hazmat event, considering factors like ventilation systems and building materials.
  • Procedures to seal off affected areas and prevent hazardous materials from infiltrating designated shelter locations.
  • Communication protocols for notifying all school occupants of the shelter-in-place order, and for staying informed of updates from emergency management agencies.
  • Plans for addressing the needs of individuals with disabilities and access or functional needs during shelter-in-place situations.

Training Staff and Administrators

Proper training of school staff and administrators is a vital component of effective hazmat response plans.

Staff may benefit from training in the following areas:

  • Recognizing the signs and symptoms of a hazardous materials release, as well as understanding the potential risks associated with different types of hazardous substances.
  • Familiarization with the school’s emergency response plan, specifically the Shelter-in-Place Annex.
  • Safe operation of any specialized equipment or tools needed during shelter-in-place situations, such as portable radios or materials for sealing off doors and vents.
  • Executing the appropriate response procedures for different hazmat scenarios, including steps to take after the immediate threat has passed.

By combining a thoughtful and thorough approach to planning, collaboration, and training, schools can effectively implement shelter-in-place hazmat drills, helping to ensure the safety and well-being of students, staff, and visitors during potentially dangerous hazmat incidents.

Conducting the Shelter-in-Place Hazmat Drill

Activating the Drill

To begin the shelter-in-place hazmat drill, a member of the school administration should activate the drill using a predetermined method known to staff and faculty.

This may include a specific announcement made over the public address system or sending out a mass notification through cell phones.
