Answer: The FIRE SIZE should be taken into consideration when using a fire extinguisher.

Explanation:

Firefighting is defined as the steps followed to put off and prevent spread of unwanted fire. The particular technique and equipment that is used to put out fire will largely depend on the root cause of the fire and location of the fire itself.The fire may be caused by electricity or flammable liquids/ chemicals. There are different equipments that can be used to put out fire, these include:

--> Fire blanket: to extinguish fire on personal clothing or a small fire on the floor or bench.

--> Buckets of sand or dry soil (kept free of refuse): this is used to extinguish a free flowing liquid fire.

--> Buckets of water: to extinguish paper, fabric and wood fires. Water, however, must never be used to extinguish an electrical fire or one caused by a flammable chemical.

--> Dry powder chemical FIRE EXTINGUISHER: to extinguish electrical fires and fires caused by flammable liquids.

Generally FIRE EXTINGUISHER is an equipment used in emergency situations to put out SMALL fire to avoid it's spread. Prior to fighting any fire with a portable fire extinguisher, you must take into consideration the FIRE SIZE as not all fire can be extinguished using a portable fire extinguisher.

Many people put out SMALL FIRE quite safely using a portable fire extinguisher. However, death or serious injury can occur by tackling a fire which is beyond your capabilities. Only tackle a fire in its very early stages and always ensure you put your own and other peoples safety first.

if the recommended daily allowance (rda) for vitamin c is 60 mg per day and there are 70 mg of vitamin c per 100 g of orange, ho
joja [24]

Recommended daily allowance (RDA) is the nutritional requirement and uptake of the food. One has to eat 7 oranges each week so as to meet the requirement.

<h3>What is RDA?</h3>

RDA is the recommended daily allowance that defines the level of the essential nutrients that a person consumes for a healthy lifestyle that is defined by Food and Nutrition so as to meet the required nutrient amount.

Given,

RDA of vitamin C = 60 mg/day

100 gm orange = 70 mg Vitamin C

So for one week, it is calculated as:

7 × 60 = 420 mg

The vitamin C in 100 gm oranges = 0.0007 and 1 oz = 28.3495 grams.

So, 3 oz = 3 × 28.3495 grams = 85048.5 mg

The amount of vitamin C in 85048.5 mg is calculated as:

0.0007 × 85048.5 = 59.53 mg

Number of oranges to be consumed each week = 420 ÷ 59.53 =7

Therefore, 7 oranges must be consumed in a week.

How does left ventricular failure cause pulmonary edema.
castortr0y [4]

Answer:

Heart failure is frequently the cause. Pressures in the heart rise when a sick or overworked left ventricle can't pump out enough of the blood it receives from the lungs. Fluid is pushed past the blood vessel walls and into the air sacs by the increasing pressure.
