A severe fire breaks out in a crowded shopping mall due to a short circuit. Why is it advised to crawl close to the floor rather than walk upright while escaping through the smoke?
Smoke and hot poisonous gases rise upwards, leaving cleaner cooler air near the floor
Crawling helps you move much faster than running
The floor is completely fireproof and will not catch fire
Smoke only affects the eyes if a person is standing upright
Solution
Hot smoke and dangerous toxic gases are lighter than air and rise towards the ceiling, so the air near the floor remains cooler and safer to breathe.
