Emergency plans are being formulated so that rapid action can be taken in the event of an equipment failure. It is predicted tha

t if a particular pipeline were to rupture, it would release ammonia at a rate of 100 lb/s. It is decided that anyone exposed to potential concentrations exceeding 500 ppm must be evacuated.

Answer:

Ammonia gas a hazardous gas to our health, when we are exposed to it for a long time. The gas is lighter than air, that means it's high concentration may not be noticed at the point of leakage, because it flows with the wind direction. Ammonia gas detector are used to determine the concentration of the gas at a particular place. We can use the dispersion modelling software program to know the exact position, where we can place the gas detector, which would be where evacuation is needed.

During evacuation, when the concentration of the gas has increased, a self-contained breathing apparatus should be used for breathing, and an encapsulated suit should be worn to prevent ammonia from reacting with our sweat or any other chemical burn. A mechanic ventilation will also be needed in the place of evacuation, so that the ammonia concentration in that area can be dispersed.

Answer / Explanation:

Ammonia is considered as a high risk to health chemical gas when exposed to the skin and other features of the body such as the eye. Exposure to ammonia in the range of 300 ppm could lead to immediate mortality or life threatening conditions. When ammonia is exposed to fire it has a very high tendency of exploding.

Now, if we refer back to the question where we are being asked on what recommendation we will propose as to the evacuation distance downwind in the event of exposure to ammonia of potential concentrations exceeding 500 ppm.

The first and most important step to take is to move the exposed individuals to a location of fresh air to avoid chocking of the victims and in the case where the victim has inhaled some amount of ammonia, a breathing aid is immediately administered or a self-contained breathing apparatus should be used.

After which we rinse or wash the eyes of the exposed victims with a lukewarm like water.

Most importantly, we make sure we bath all affected areas properly with water. Then we move forward to detecting the source of the leakage.  

Litmus paper or a sulfur stick can be used to detect the source of leaking ammonia. Ammonia can be in gas or liquid form. The liquid form is flammable so only use a burning sulfur stick to detect small leaks of ammonia gas

On doing this, we direct the leak through a flue or vent to properly disperse the leaked or leaking ammonia.

We should also note that during this process, an encapsulated suit should be worn to prevent ammonia from reacting with our sweat or any other chemical burn

Affect the amount and rate the alcohol reaches the<br> bloodstream.
just olya [345]

Answer:

Answer to the following question is as follows;

Explanation:

The amount of alcohol consumption can be influenced by a variety of things, including food.

The proportion and pace at which alcohol reaches the circulation is affected by drinking rate, body mass, and the size of the beverage. Alcohol enters your system as soon as it reaches that first sip, as per the National Institute on Drug Abuse and Alcoholism. After 10 minutes, the results are noticeable.

2.1 What is the minimum number of pins required for a so-called dual-op-amp IC package, one containing two op amps? What is the
cupoosta [38]

Answer:

8 for dual-op-amp package, and 14 for quad-op-amp

Explanation;

This is because every op-amp has 2 input terminal 4 pns

So one output terminal that is 2 pins which are required for power

and the same for a minumum number of pins required by quad op amp which is 14

What are the 3 dimensions that used in isometric sketches?
noname [10]

Answer:

The three dimensions shown in an isometric drawing are the height, H, the length, L, and the depth, D

Explanation:

An isometric drawing of an object in presents a pictorial projection of the object in which the three dimension, views of the object's height, length, and depth, are combined in one view such that the dimensions of the isometric projection drawing are accurate and can be measured (by proportion of scale) to draw the different views of the object or by scaling, for actual construction of the object.

Relay contacts that are defined as being normally open (n.o.) have contacts that are:_____.
Reptile [31]

Relay contacts that are defined as being normally open (n.o.) have contacts that are open only if  the relay coil is known to have de-energized.

<h3>What is meant by normally open contacts?</h3>

Normally open (NO) are  known to be open if there is no measure of current that is flowing through a given coil but it often close as soon as the coil is said to be energized.

Note that  Normally closed (NO) contacts are said to be closed only if the coil is said to be de-energized and open only if the coil is said to carry current or is known to have energized.

The role of relay contact is wide. The Relays are tools that are often used in the work of  switching of control circuits and it is one that  a person cannot used for power switching that has relatively bigger ampacity.

Therefore, Relay contacts that are defined as being normally open (n.o.) have contacts that are open only if  the relay coil is known to have de-energized.
