Multiple Choice

What is the recommended approach when you are approaching a hazmat scene?

Approach a hazmat scene from the upwind and uphill direction. This places you against the plume and above any potential vapor pools, reducing the chance that you’ll inhale or come into contact with contaminants. Wind-driven vapors move with the air, so approaching from upwind keeps the contaminants blowing away from you. Many chemical vapors are heavier than air and will tend to settle in low areas and roll downhill, so staying uphill helps avoid these pooled vapors. Always use appropriate PPE and monitor wind shifts, adjusting your position as conditions change.
