2021 L2 Engineering Hydraulic Tools

 What are hydraulic power tools ? Hydraulic power tools are powered by pressurized liquid fluid. Just like air compressors but instead of using pressurized air you use pressurized liquid.

How do hydraulic power tools work ? Hydraulic machines use a pump to pressurize hydraulic fluids, compressing it against a tool like a jack, lifting it up, and allowing the jack to hold something up, under the pressure.

What are the different types of hydraulic power tools ? Some Hydraulic power tools are manually pumped using your hands or your feet. We need to use a pump to create the pressure that goes through the hydraulic tools. Others run off mains electricity.

What is the correct type of PPE gear to use when operating hydraulic tools ? The essential PPE gear to wear in the workshop are safety glasses and ear muffs. These are a must no matter the job you are doing. Wear safety gloves when operating a hydraulic tool and also wear it to protect your hands from debris. How many types of PPE gear you wear is definitely up to what type of hydraulic tool you are using. There will always be signs around the workshop telling you what PPE gear to wear and they might also be shown on the description list of the tool.

SAFE USE OF  MAINS POWERED TOOLS AND EXTENSION CORDS 

What is a mains powered tool ? Mains power is an alternating current electrcity supply. Mains power tools are powered through the electricty running through the electrical cords. The electrical cords are used to plug in an electrical outlet so that electricity flows through the tools.

Where are you likely to use Mains Power/Power Tools ? You are most likely to find a Mains Power Tool in a workshop near an outlet. Basically wherever you can find an electrical outlet, is also where you can use Mains power since it runs of the electricity that comes from the walls connected to the electrical outlet. We can find different types of mains powered tools in the workshop that is available to us.

3 examples of Mains Powered tools I have used before :

Biscuit Joiner

Power Drill

Band Saw

Describe and Explain the task you used it for ?

1. A Biscuit Joiner is used to make circular shapes in a piece of wood to join to wood pieces together. I used a Biscuit Joiner to cut a circular shape on a piece of wood that matches the size of the biscuit,and then joined the three pieces of wood together to build my table.

2.  A Power Drill is used to put holes into your work whether it be wood or metal. I used a power drill, to drill holes into my table, and work bench so that I can then apply the appropriate screw that needs to hold my work together.

3. A Band Saw is used to cut through materials such as wood, and metal. I used the band saw to cut a curved shape. I drew lines on the wood before I used the band saw because I would know where to follow and cut. So I made the curved shape for the support for my table.

General Safety around Electricity.....

What to look for ? Before using any machinery with wiring in the workshop, make sure you check for exposed wires, so that no accidents happen. Be careful when using cord-and-plug power tools if the guard is removed. In the event of someone getting an electrical shock do not touch them, because the electrcity will transfer on to you.

What do I do if something is wrong ? If any wires are exposed do not turn on the switch of the tool and contact your teahcer immediately. If the guard isn't on just make sure you don't trip on the cord. If someone is getting an electrical shock, make sure you step away from them and contact your teacher, then contact the authorities.

What is meant by RCD ? An RCD is a corded device that is programmed to break an electrical circuit to prevent serious harm from an ongoing electric shock.

What is meant by Double Insulation ? Double insulation is insulation that consists of both basic insulation and supplementary insulation. Equipment such as hand-held domestic electric drilling machines has the additional safety precaution of double insulation.                                         -Website for Meaning

Safety checks and safe working practices when using a mains powered tool ? Check for exposed wires, so there is no electrical shock and also attach the rcd to the cord if anything wrong happens accidentally.

Hazards and dangers of extension cords ? Make sure you look around for the wires on the ground because you might trip and fall. Also if the cords are in a round loop it will heat up and cause a fire.

Safe use of extension cords ? Attach the guard to the cords so you don't trip on the wire. Also untie the cord if it has a loop so you can prevent overheating it.

2021 L2 Engineering Air Tools

Here is a diagram of a air compressor

What is a pneumatic power system/source?A pneumatic power tool is a type of power tool used in the workshop. A pneumatic power source is powered by air. Pneumatic power tools can only be used when the firing pin is opened and then opens the valve inside the tool, which then allows pressurised air to flow through the tool. The most common pneumatic power source is an air compressor. 

What is an air compressor ? It is a machnine that generally runs of electrical power. The wires are connected to mains power. Air compressors suck in the air in the atmosphere, and compress the air in the reservoir/tank. The sizes of the compressors are important too because the bigger they are the more air pressure they can hold.

Instructions on how to use an Air Compressor

Dangers and Hazards when using an Air Compressor :

1. Air Compressors run of mains power, so watch out for cords on the floor because you might trip and injure yourself.
2. Don't point the air compressor hose at yourself or anyone, obviously this would be really stupid to do because once the compressed air is injected in to your body, dangerous injuries from it may include embolism, ruptured ear drums, and ruptured organs just to name a few.
3. Make sure to check the electrical outlet is plugged in correctly, because if it isn't it may result in a elecetrical shock for your operators or irreversable damage on the machine.
4. Noise from the air compressors can cause hearing loss.
5. Gas and Diesel powered Air Compressors can produce dangerous fumes, so it's important to use them outside.

General PPE Gear when using an Air Compressor 

Wearing PPE gear is mandatory when dealing with an Air Compressor because it a dangerous machine to use. 

1. Wear goggles shield your eyes from moving air particles.
2. Wear a face shield this also covers your face from moving air particles.
3. Wear ear muffs so it can protect your hearing.
4. Wear overalls to protect yourself just incase you accidentally point the hose at yourself.

There are different ranges of air tools available in the workshop but there are four Air tools we can possibly use and those Air tools are an Impact Driver, Dust of Gun, Air Ratchet, and lastly a Air Rivet Gun. When using these four tools there are appropirate PPE gear to wear to ensure your safety.

Firstly  Impact Drivers are used to drive in large amounts of fastners such as long screws and lag bolts. When using an Impact Driver make sure you wear  safety goggles to protect your eyes, and ear muffs to protect your hearing. An Impact Driver gives you a bit of a kick so make sure your hands are well prepared. Also wear safety boots so if you were to accidentally drop it on your foot you wouldn't get your foot injured.

Secondly a Dust of Gun is used to clear dust off on your work tables. When you're using a Dust of Gun make sure to wear safety goggles to protect your eyes from the dust that is being dusted off, wear ear muffs to protect your ear drums. Wear overalls to protect your clothing from dust and if you were to accidentally point a high Air pressured gun at yourself. Safety boots are also a must, because if the gun were to be pointed at your foot, you would be protected by the boots you are wearing.

Thirdly when using an Air Ratchet make sure to wear safety goggles because if any metal dust somehow makes it way into your eyes, wear ear muffs because Air Ratchet makes noise and you want to protect your hearing and you also can't always be to sure. Also wear safety boots in the event you drop the air tool on your foot.

Lastly an Air Rivet Gun is used to fasten two pice of metals. When using an Air Rivet Gun wear safety goggles to protect your eyes, and wear ear muffs to cancel out the noise. Wear overalls to protect your clothing. Also wear safety boots to protect your feet.
