  Video: Ingenious Video 3: This Sandwich Will Save Your Life in an Arc Flash Mark as Favorite (3 Favorites)

  It’s never fun when your clothes catch on fire. And while “stop, drop, and roll” may be a good idea sometimes, in more extreme cases, you need a better plan. Every day, industrial workers, firefighters, and soldiers risk fiery situations that might seem hard to imagine. In an arc flash event, for one, temperatures can jump to metal-melting levels in milliseconds. How can anyone possibly survive that? Well, take a tip from a club sandwich, because it’s all about the layers. The composite fabrics that protect life and limb in these situations rely on some incredible, multilayered chemistry, including the ability to quickly form a protective carbonaceous crust around the wearer.

Each episode investigates a different topic related to how leading-edge chemistry is taking on the world’s most urgent issues to advance everyone’s quality of life and secure our shared future. This episode investigates Omega-3’s, the essential nutrient that humans have to get from fish. However, fish don’t make their own Omega-3’s, and like humans, must get them from an important part of their diet, algae. But with over-fishing considerations and fish-farming limitations, scientists are working to develop a new way to harvest Omega-3’s to maintain stability.
