Excerpt:
Oil is on fire, don’t use water to extinguish it. "When the enemy comes, the general defends; when fire starts, water drowns," using water to extinguish fire seems to be the most natural thing in the world. But if the oil pan or gasoline drum catches fire, never use water to pour it on, because water will make the fire even bigger.
Originally, oil is lighter than water. When oil catches fire, pouring water will not only fail to cover the flames but will instead cause the oil layer to float and splash everywhere, greatly increasing the contact area with the air, and the fire will grow stronger and stronger. Therefore, when oil catches fire, you should use foam or dry chemical fire extinguishers to put it out, not water.
Why should superficial skin scrapes not be bandaged?
When it is only a superficial scrape without deep wounds, it is best not to bandage it with gauze. This will prevent the scraped area from breathing, and in a moist and warm environment, it will be more prone to infection by anaerobic bacteria, causing inflammation and delaying healing. Therefore, after a superficial scrape, it is important to clean and disinfect the area, apply some anti-inflammatory ointment, and avoid bandaging with gauze.
