To know electricity, we must first explain electrons and charges.
I'm sorry for suddenly difficult story.
The smallest unit of matter is an atom, which consists of a central nucleus and electrons rotating around it. The protons in the nucleus are positive and the electrons are negative (charged). This charged substance is said to have a charge,and the unit of its size is called Q.
No open holes or breaks exist in surfaces of either the door or frame.
Glazing, vision light frames and glazing beads are intact and securely fastened in place, if so equipped.
The door, frame, hinges, hardware and noncombustible threshold are secured, aligned and in working order with no visible signs of damage.
No parts are missing or broken.
Door clearances do not exceed three-quarters inch under the bottom of the door (as provided in Section 4.8.4) and one-eighth inch at the top, hinge and latch edges of the door (as provided in Section 22.214.171.124).
The self-closing device is operational; that is, the active door completely closes when operated from the full open position.
If a coordinator is installed, the inactive leaf closes before the active leaf.
Latching hardware operates and secures the door when it is in the closed position.
Auxiliary hardware items that interfere or prohibit operation are not installed on the door or frame.
No field modifications to the door assembly have been performed that void the label.
Gasketing and edge seals, where required, are inspected to verify their presence and integrity.
Labels are clearly visible and legible.
Signage affixed to a door meets the requirements listed in 4.1.4.
Similarly, paragraph 5.2.1 of NFPA 105 outlines the following visual inspection criteria for smoke doors:
Doors shall be operated to confirm full closure.
Hardware and gaskets shall be inspected, and any parts found to be damaged or inoperative shall be replaced.
Further requirements in NFPA 101 Section 8.5.4 limit the clearances for smoke barrier doors as provided above for fire-rated doors.

Your contractor might need to special order a few components, and the time to start this process is before the destruction of your space has started.
Choose a Start Date - The scheduled completion date, along with the contractor's schedule, will assist to set the beginning date for your remodel. Bear in mind, however, that unforeseen problems can crop up at any moment. While remodeling a bathroom may take less time than a complete scale kitchen remodels, it pays to give you and your contractor ample time to start and also complete the job typically a month or more ahead of the anticipated event.

Working with a builder to remodel your bathroom can save time, eliminate frustration, and assist you to stay in your budget.
Typical fire extinguishing systems found in commercial and industrial locations include sprinklers, carbon dioxide, clean agent, and dry/wet chemical agents. Another fire extinguishing technology available, but less common, is condensed aerosol. These systems take advantage of the well-established fire suppression capability of solid particulates, with potentially reduced collateral damage associated with traditional dry chemicals. However, there are some concerns in regard to collateral damage to computers and other sensitive electronic equipment.
History Of System
Potassium was first isolated by Davy in 1807 through the electrolysis of molten potassium hydroxide (KOH), from which the name potassium is derived . At roughly the same time (1807 – 1808) Gay-Lussac and Louis Jacques The nard obtained the element through the reduction of molten potassium carbonate with iron filings in an iron crucible.
How do Condensed Aerosol Systems Work?
The idea of the work of Fire Pro depends on the transformation of the solid material into the gaseous substance when exposed to high temperatures. The gas of the Aerosol comes out as a misty gas consisting of calcium carbonate, nitrogen, water vapor and carbon dioxide. The fog gas extinguishes the fire by breaking the chemical reaction chain of fire and completely.(See in PIC).
1. Easier installation - no piping, pressure cylinders, special supports or valves are required, thus reducing installation time and labor costs considerably. 2. Environment friendly and nontoxic. 3. Cost less if compared to other system. 4. Easy maintenance without the need for pressure testing, weighing, pressure/leak detection, filling, etc. 5. Self-activation temperature 300 •C.
1. Releases misty gas, which hinders the process of evacuation during the fire. 2. It is not recommended to be installed in populated areas (e.g patient areas - patient critical areas…..). 3. Shall not be used on deep-seated fires in Class A materials (i.e. paper, wood, cloth, rubber and many plastics). 4. Shall not be used on certain chemicals or mixtures of chemicals, such as cellulose nitrate and gunpowder, that are capable of rapid oxidation in the absence of air. 5. Find chemical reactive on metals such as lithium, sodium, potassium, magnesium, titanium, zirconium, uranium, and plutonium.
