Overview

Summary

Hazardous materials (often called “hazmat”) are substances that can pose a risk to human health, property, or the environment. These include chemicals, fuels, gases, biological agents, and radioactive materials that may be toxic, flammable, corrosive, or explosive. 

 

Preparedness

Preparedness

Being prepared can reduce the risks associated with hazardous materials incidents. Households and communities should: 

  • Learn about the hazardous materials commonly used or transported in their area.  
  • Follow local emergency alerts and warning systems.  
  • Prepare an emergency kit with essentials such as water, food, first aid supplies, and protective items like gloves and masks.  
  • Identify safe shelter areas in the home, such as a room that can be sealed to prevent outside air from entering.  
  • Develop and practice an emergency plan, including evacuation routes and communication methods with family members.  
Prevention

Prevention

Preventing hazardous materials incidents requires proper handling and awareness: 

  • Store chemicals safely and according to instructions, keeping them out of reach of children.  
  • Never mix household chemicals unless directed, as this can create dangerous reactions.  
  • Dispose of hazardous waste properly through approved collection programs.  
  • Follow safety guidelines when using fuels, cleaning agents, or other potentially dangerous substances.  
  • Support and follow community regulations regarding the transport and storage of hazardous materials.  
Response

Response and Safey Measures

If a hazardous materials incident occurs: 

  • Stay informed through official alerts and follow instructions from emergency authorities.  
  • Evacuate immediately if advised, or shelter in place by closing windows, doors, and ventilation systems.  
  • Avoid contact with any spilled or airborne substances.  
  • Seek medical attention if you experience symptoms such as difficulty breathing, dizziness, or skin irritation.  
  • Do not return to affected areas until authorities declare them safe.
