Emergency lights are a standard configuration in new commercial and high-occupancy residential buildings, such as university dormitories, apartments and hotels. Most building codes require that they must also be installed in older buildings.
Almost every commercial and high-occupancy residential building has installed modern emergency lighting. The lamp consists of one or more incandescent bulbs or one or more high-intensity light-emitting diodes (LEDs). The emergency light is usually a PAR 36 sealed beam or a wedge-shaped base light. All units have some kind of equipment to focus and enhance the light they produce. It can be a plastic cover on the fixing device or a reflector placed behind the light source. Most individual light sources can be rotated and aimed at the places where lighting is most needed in an emergency, such as towards the direction of a fire exit. Modern luminaires usually have some kind of test button, even if the main power is still on, the button will temporarily cover the device and make it turn on the light and use battery power. Modern systems operate at relatively low voltages (usually 6-12 volts). This not only reduces the size of the battery required, but also reduces the load on the circuit to which the emergency light is connected. Modern lamps include a small transformer in the base of the lamp, which reduces the voltage of the main current to the low voltage required by the lamp. Batteries are usually made of lead-calcium and can be used for 10 years or more with continuous charging. During a power outage along the exit path, US fire safety regulations require the battery to have at least 90 minutes of battery life.

The jump starter is a backup power source that you carry with you, a very good item. The main advantage is that you can quickly start a broken battery without the need for other vehicles. The jump starter acts as its own backup power source. Most devices are also equipped with additional power sockets to power mobile phones and laptops. The jump starter is very simple to use and operate.
Proceed as follows:
Before connecting the cable, turn off the ignition switch.
Clamp the positive (red +) clamp on the positive terminal of the vehicle battery (for negative grounding system), or fix the starting point of the spare vehicle as recommended by the vehicle manufacturer.
Fix the negative (black-) clamp on the vehicle ground (fixed metal parts, such as the frame).
Make sure that the cables are not in the path of moving engine parts (belts, fans, etc.).
Start the vehicle (turn on the vehicle ignition switch). If the vehicle does not start within 6 seconds, please allow the jump starter to cool for 3 minutes before attempting to start the vehicle again, otherwise the vehicle may be damaged.
When the vehicle starts, disconnect the negative (-) battery clip from the frame and then put it back in the holster.
Disconnect the positive (+) clip, and then put it back into the holster.
Recommended charging time for beginners
After the single jump starts: 1 hour
After multiple jumps: 12 hours or all night
After being used as a portable power source: 24-36 hours

1. Understand the basics
Analyze the requirements of the equipment to be powered. Are you going to use compressors to power mechanical or pneumatic tools, or to inflate tires? If you plan to use a tool that requires high flow, you may need a compressor with a box. If you plan to use it only for airbrushes or filled tires, you may need a portable compressor without a fuel tank. Since there is no storage tank for compressed air, the type without storage tank will run continuously, which is usually not a problem, because they are usually very small, so the noise is very small.
In particular, consider the pressure and volume requirements of any tool you may use. Obviously, heavy tools require more pressure, which in turn requires more volume. If you fail to choose a compressor large enough to achieve the intended use, you will find yourself waiting for the tank to refuel on a regular basis, thereby reducing work efficiency.
If a portable air compressor is used for the spray gun, for example, a small tank capacity of 5 liters (1.3 US gallons) and a continuous air pressure of about 30 psi are sufficient.
2. Understand the available compressor types.
Essentially, there are two different types of air compressors: reciprocating and rotary screw. The most common type you might see somewhere is the reciprocating piston type. It has a cylinder with a piston that can move up and down and a one-way valve on top of the moving piston. Some air compressors utilize a dual piston device to obtain higher flow and / or pressure. Another type of air compressor is a rotating screw. They are designed for continuous use and are often used with tools that run for a few seconds (or minutes) at a time, such as impact wrenches and air guns, and in industrial applications.
Piston compressors are divided into single-stage and two-stage. Single stage pressure can reach 150 psi.
Two-stage compressors use two pistons of generally different sizes to provide a pressure of about 200 psi. The larger piston compresses the air to approximately 100 psi, and the second piston compresses the air to approximately 200 psi. Note that a single-stage compressor may have two pistons, but it is still considered a single-stage because the second piston has the same size and the maximum pressure is only 150 psi. The advantage of this design is that it compresses air faster than single-piston compressors. Just because the air compressor has dual pistons does not mean that it is a two-stage compressor.
A single-stage compressor is sufficient to power most pneumatic tools, caulking guns, spray guns, glue guns, and of course can inflate tires and rafts. When the owner expects a higher utilization rate, both single-stage and two-stage dual-piston compressors are more commonly used.
3. Technical parameters of air compressor
Check the horsepower (HP) of the air compressor. The power range of air compressors is usually between 1.5 and 6.5 HP. There are air compressors with larger HP capacities, but they are generally reserved for industrial use and provide greater psi. Many blogs and articles online indicate that horsepower ratings have changed in recent years. If you want to compare today's model with an older model, it is best to look at the flow rate instead of the HP rating. Small-scale applications do not require as much horsepower as industrial applications.
Although horsepower is an important sign in determining your air compressor, it should not be unique. If you can find it, the more valuable will be the CFM level or cubic feet per minute. Please read the following to learn more about CFM.
Try to view cubic feet per minute (CFM). CFM is a measure of volume flow. It's easy, right? The difficult part is that the CFM varies with the psi of the compressor, which means that two tools with different psi may not necessarily have a CFM that can be simply added together, and this is exactly what you want to do. This is the tricky place. Let's try to keep it simple:
Look for or ask about standard CFM (SCFM) when evaluating compressors. At 68 ° F (20 ° C) and a relative humidity of 0%, the standard CFM measurement is 14.5 PSIA. [7] (If you choose not to use SCFM, make sure to use CFM numbers that are fixed at the same psi.)
When you get the SCFM of all pneumatic tools that will be used at the same time, add up their SCFM and then add 30% as a safety buffer. This will give you the maximum CFM usage required to complete the job. When choosing an air compressor, you want to be close to this number, so as not to waste time buying a compressor that is too small, and not wasting money to buy a compressor that is too large.
For example, suppose you are using a grease gun (~ 4 CFM @ 90 psi), a frame nailer (~ 2 CFM @ 90 psi) and a double sander (~ 11 CFM @ 90 psi) at the same time. Add all the CFM to obtain 17 CFM at 90 Cpsi as... less -
