You need to open the bomb shelter ventilation from inside. This is done by pushing the center of the bomb shelter ventilator, which slides open.
When you need to close the ventilator, also do it from outside so that the process can be made easier.
Here is what you should know about the opening and closing of the bomb shelter ventilation procedure:
The bomb shelter cover removal
The first thing to do is to ensure you turn off the HVAC system power. Carefully hold the cover in the middle and remove all the screws safely.
You need to know that a ventilation cover is both decorative and functional. It is usually easy to remove the cover but can be harmful if kept away from the opening of the duct.
If you are a homeowner, you should be able to do the task of removing the ventilation cover. It is a straightforward task that anybody can perform.
Mostly, the cover of the vent is placed on the wall or floor and held in place using some screws.
To remove the screws, you have to use a screwdriver. In a counter-clockwise direction, twist them and remove them.
What follows is that you just lift the cover and remove it. You should not pull on it since this can cause damage to the flooring or surrounding wall. Otherwise, pry it out using a screwdriver.
Many households do not open their bomb shelter ventilation often. The majority do not realize that the covers or grilles need cleaning once in a while, alongside biannual removal.
The bomb shelter environment is well maintained, which makes the bomb shelter environment a difference in the quality of air.
The ventilation cover functions
The design of the ventilation cover is like a grille, so it has many functions. You can regularly close or open the ventilation cover to permit frequent air circulation or to block the air from getting inside the bomb shelter.
Some ventilation covers can validate adjustment of the direction of the air flowing into the shelter by adjusting the grille angle.
The ventilation covers prevent objects from falling into the bomb shelter through the duct. Also, debris from the air that may flow or enter the bomb shelter via the duct is prevented.
In most cases, the vents are located away from furniture or out-of-the-way spots. It is advisable not to leave them removed for a long period of time.
Children can be tempted to reach their hands into the opening or pets can crawl into it and it can pose a danger to them due to the sharp screws and metals present.
Survival kits are important. In reality, survival situations have never been preceded by script revisions or production meetings.
When you least expect them, is when they do happen. So it is important that you be prepared for anything that might come your way.
During an emergency, the safest place in my house is the bomb shelter, and it should be maintained thoroughly in preparation for emergencies.
Your pets should have somewhere prepared for them to pee inside the shelter. They are not allowed to go outside during an emergency.
There are two vents in a bomb shelter: the supply vent and the return vent. Return vents control the temperature by pulling air out of the shelter. Supply vents blow cold or hot hair inside the shelter.
Closing the ventilation
It is recommended that you do not close your bomb shelter vents more than 60% of the way.
I use the stepladder to reach the open ventilation that I want to close. Make sure you prevent the ladder from falling by locking it into place.
Go up the ladder up to a point where the vent you need to close can be reached comfortably.
Reach for the dial or the switch on your vent type. Square and rectangular ventilators have a switch on either side.
Circular vents have their adjustment or dial at the center, and they can be opened by moving the switch to the right and can be closed by adjusting the switch to the left.
By adjusting the switch downwards or upwards or by turning the dial anticlockwise or clockwise, you close or open the louvers.
For any other that needs adjustment, you ought to repeat the same procedure.
You can now place the ventilation cover back in its original position with the use of screws and a screwdriver. Twist the screws using the screwdriver in a clockwise direction to lock them into their position.
