Answer»

(a)Ans. When a persons who is on fire runs the air SURROUNDING him appears to flow, this supplies more oxygen (from flowing air) to the fire, which supports burning and causes the flames to grow, hence a person should not run.(b)Ans. We should not operate any electrical switches when there is a gas leak because the electrical switches generate sparks while being switched on and off.(c) Ans. In case of a heatstroke after 15-20 minutes, we feel thirsty. That is why we should to drink ORS.(d) Ans. This could lead to a situation where the contents inside OVERFLOW and EXTINGUISH the flame, leading to gas leaks. That is why, we should not light any matchstick in the kitchen whan there is gas leak.(e) Ans. when we open doors and windows the air circulation take place in the room so LPG gas get out with the air spread in atmosphere. (f) Ans. As the fire blanket completely surrounds the person whose clothes caught fire, it seals the person's body SURFACE around the fire and cut's off the oxygen supply to the fire, thereby putting it out.(g) Ans. They help minimize swelling by keeping fluids from gathering at the injury site. Compression can also be applied through the use of compression sleeves, but these are usually used for long term pain or blood circulation management. Common conditions where compression wrapping is used include: wrist or ankle sprains.Hope, This helpful.Mark me as BRAINLIEST and follow me.
