In one sentence, describe what the following article is about: Using a buddy system in the lab is an important way to stay safe: if anything happens to you in the lab, someone is there who can help you or go for more help if needed. Ask a teacher, friend, or colleague to work with you in the lab as you are learning the ropes. If it's not possible to have someone with you in the lab, at the very least you should let people know that you are using it. Tell a friend or parent that you will call when you're done, and give them an expected time, so that they will know if you don't get in touch then something is wrong. Every chemistry lab is set up slightly different, which means that the things you need to stay safe may be hard to find in an emergency. Even if you are just helping someone else in a lab, you may need to locate safety gear in case they are incapacitated. Locate the following before doing any kind of work in a chemistry lab. All exits to the lab (check to see if windows are locked, and unlock them if possible) Fire extinguisher and fire blankets Chemical shower Eye wash station First aid kit Telephone Chemicals can be harmless (such as water) or highly corrosive and dangerous (like sulfuric acid). If a chemical is unlabeled and you are not familiar with it, leave it alone until an instructor can tell you what to do. Never sniff directly from a container with an unknown chemical. Some chemicals are highly toxic and can kill you if you inhale them. You can use one hand to "waft" the scent toward your nose from the top of an open container, rather than inhaling it. Similarly, never taste an unknown chemical. Doing so could be fatal. If you are in school, do not deviate from the lab procedure given to you by your instructor, such as by substituting another chemical or adding them in inexact quantities. If your instructor wants you to make a deviation, do so only with her supervision. Every detail in a lab procedure matters, including which chemical to add to the other and in what order, the exact temperature to heat it to, amounts to measure, or any other details given. If you spill any amount of a chemical on yourself, wash yourself immediately with cool water. Depending on where you've spilled the chemicals, you may need to use an eye wash station, hand washing sink, or an emergency chemical shower. If you've spilled harsh or corrosive chemicals on your clothes, you may need to remove the clothing, or even strip naked if your clothes are saturated. Nobody wants to get naked in front of their lab colleagues, but it is better than living with burns on your skin! Similarly, you should not prepare food in the lab or store it there. Even if you are careful to keep the food away from contact with chemicals, your food may still become contaminated with chemical fumes. For the same reason, never smoke, chew gum, or apply cosmetics in a lab. When you finish a lab, you should leave it how you found it. That means replacing everything where it belongs or leaving it where your instructor prefers. A clean lab is a safer lab! Be sure to push your chair back in and close all cabinets and drawers before you leave, to ensure that the lab is safe for the next users.
Summary: Never use a chemistry lab alone. Familiarize yourself with the layout before working. Never handle chemicals you are unfamiliar with. Follow the lab procedure carefully. Wash chemicals off of you immediately. Never eat or drink in the lab. Put everything back where you found it.

In one sentence, describe what the following article is about: Look at an automotive store to see what options they have for installation kits. Get a kit that has 8- or 10-gauge wiring so they can carry the full current without overheating and melting. Open the kit and separate all of the components so you can stay organized while you're working. Installation kits usually cost around $1520 USD. The installation kit will include a red power cable, black ground cable, blue remote wire, RCA cables, in-line fuse, and connectors for all of the wiring. It does not matter what kind of stereo you use the amplifier with. You can use the stock car stereo or use one that's after-market. Check the vehicle's engine bay so you can see if the battery is on the driver or passenger side. Look in the footwell that's on the same side as the battery to see if there's a cutout in the firewall, which is the metal panel between the engine bay and interior. If there's already one with wires coming through it, you can also feed the amp power cord through it. If you don't see a hole in the firewall, use a drill bit made to bore through metal and create a new hole. Make sure there isn't anything in the engine bay where you plan on drilling the hole. Start from the interior of your vehicle, and push the red cable through the middle of the hole. Feed about 45 inches (1013cm) of the cable before going to the engine bay and pulling it from the other side. Pull enough of the cable through so it reaches the battery. The color of the power cord may vary depending on the installation kit you purchased. The power cord is the only wire that goes through your vehicle's firewall. Find the thin blue wire from the installation kit, and feed one end through the hole in the dashboard behind the stereo. Push the wire down until you can see the end come out in the footwell. Line up the remote wire with the power cable so you can run them at the same time. The remote wire turns on the amplifier when your stereo starts so it doesn't drain the battery. The remote wire may also be called the turn-on wire. Position the wires so they run along the floor on the same side of the vehicle as the battery. Place the wires into the recesses that are normally covered with the trim pieces so they're concealed later on. Run enough wire so the remote and power cables can easily reach the amplifier. Don't pull the wires tight since you're more likely to damage them. If you didn't remove the trim pieces, use a pry tool to push the wires underneath the trim. Look for the blue or silver cable that has red and white inputs on each end. Feed one end of the RCA cable through the hole in the dashboard behind the stereo system and push it through until you see it in the footwell. Run the cable along the side of your vehicle so it's in the recesses normally covered by trim. Pull the cable so it can reach where you've mounted the amp. Don't run the RCA cables on the same side as the power cable since you may pick up audio interference when you're running the amplifier. The number of speaker wires you run depends on how many speakers you want connected to the amp. Start the speaker wire near your amp and run it to the speaker you want to attach. Take out the old speaker wires from the ports before putting in the new ones in. Tighten any screws or fasteners that hold the speaker wires so they don't pull out. Repeat the process for any other speakers you want to wire. You may need to remove additional trim pieces to hide speaker wires running through your vehicle. Your installation kit may or may not have speaker wires. If it doesn't get a roll of speaker wire from your local hardware or electronics store.
Summary:
Buy an amp installation kit so you have all of the proper wires. Find a hole in your vehicle's firewall on the same side as the battery. Feed the red power cord through the hole in the firewall. Pull a blue remote wire behind the stereo head so it comes out by the power cord. Tuck the power and remote wires on the floor along the sides of your vehicle. Run the RCA cable on the opposite side of the vehicle as the power. Connect speaker wires to each speaker you want hooked up to the amp.
