What This Is: Hazardous Materials (HAZMAT) Awareness

HAZMAT awareness is recognizing and responding to emergencies involving hazardous substances. Imagine you're at a gas station and someone spills a chemical that's making people cough and feel sick. You need to know what to do to keep yourself and others safe.

Key Steps / Core Facts

• HAZMAT Incident: A situation where a hazardous substance is released or spilled, posing a risk to people and the environment. (Example: a chemical spill at a factory)
  • Recognize the hazard: Look for warning signs, labels, or colors that indicate a hazardous substance. (Example: a red warning sign on a chemical container)
  • Isolate the area: Move people away from the hazard to prevent exposure. (Example: evacuate a building with a gas leak)
  • Notify authorities: Call 911 or the local emergency number to report the incident. (Example: call 911 from a safe location)
  • Decontamination corridor: A designated area where people can be cleaned and treated after exposure. (Example: a shower or washing station)
• Personal Protective Equipment (PPE): Special gear to protect yourself from hazardous substances. (Example: gloves, mask, and suit)
  • Types of PPE: Respiratory, skin, and eye protection. (Example: a mask to prevent inhaling chemicals)
• HAZMAT Classes: Categories of hazardous substances based on their level of danger. (Example: Class 1: flammable gases)
  • HAZMAT Class 1: Flammable gases and liquids. (Example: gasoline)
  • HAZMAT Class 2: Flammable liquids and solids. (Example: paint thinner)
  • HAZMAT Class 3: Flammable solids. (Example: matches)
  • HAZMAT Class 4: Oxidizers and corrosives. (Example: bleach)
  • HAZMAT Class 5: Toxic and infectious substances. (Example: poison)
  • HAZMAT Class 6: Radioactive substances. (Example: nuclear waste)
• HAZMAT Response: Steps to take when responding to a HAZMAT incident. (Example: wearing PPE and following decontamination procedures)
  • HAZMAT Response Steps: Recognize, isolate, notify, and decontaminate. (Example: R.I.N.D.)

What Laypeople Can Do

• If you see a HAZMAT incident, move to a safe location and call 911 or the local emergency number.
• If you're in a building with a HAZMAT incident, evacuate to a safe area outside.
• If you're exposed to a HAZMAT substance, remove contaminated clothing and wash your skin and eyes with soap and water.
• If you're in a vehicle with a HAZMAT incident, stay inside with the windows closed and call 911.

Last-Minute Exam Cram

• Normal vital sign ranges: 98.6°F - 100.4°F (37°C - 38°C) for temperature, 60-100 beats per minute for heart rate, and 12-20 breaths per minute for respiratory rate.
• CPR compression depth: at least 2 inches (5 cm) – like pushing down a soda can.
• Agonal breathing is NOT normal breathing – start CPR.
• SAMPLE is a mnemonic for assessing patients: S – Scene, A – Airway, M – Movement, P – Pulse, L – Level of consciousness, E – Exposure.
• OPQRSTI is a mnemonic for assessing patients: O – Onset, P – Provocation, Q – Quality, R – Region, S – Severity, T – Time, I – Intensity.
• The 1:10:100 rule for CPR: 1 adult rescuer, 10 child rescuers, and 100 infant rescuers.
• The 30:2 ratio for CPR: 30 chest compressions followed by 2 breaths.
• The 911 rule: Call 911 or the local emergency number if you're in the US.
• The ABCDE rule for patient assessment: Airway, Breathing, Circulation, Disability, Exposure.
