Tin is often alloyed with other metals, such as copper and lead, to improve its strength and durability. Some common applications for tin include the production of tin cans, solder, and bearings.
ii. Aluminum: Aluminum is a lightweight, highly conductive metal that is highly reactive with oxygen, which leads to the formation of a thin, protective layer of aluminum oxide on its surface. This layer makes aluminum resistant to corrosion and wear. Aluminum is highly ductile and can be easily shaped and formed into various shapes and sizes. Some common applications for aluminum include the construction of aircraft, automobiles, and buildings, as well as the production of cooking utensils and electrical wiring.
iii. Rubber: Rubber is a natural or synthetic material that is characterized by its high elasticity and ability to absorb shock. It is also resistant to wear and can withstand a wide range of temperatures. Rubber is commonly used in the manufacture of tires, gaskets, seals, and other products that require flexibility and durability.
iv. Mild steel: Mild steel is a type of low-carbon steel that is relatively soft and easy to work with. It is a good conductor of heat and electricity and is relatively strong and durable. Mild steel is often used in the construction of buildings, bridges, and other structures, as well as in the production of automotive and other industrial components.

- Type of finish: Different types of finishes, such as wood, metal, or paint, may require different types of polish. For example, wood finishes may require a wax-based polish, while metal finishes may require a cleaner or a metal polish.
- Condition of the finish: The condition of the finish will also influence the type of polish that should be used. If the finish is in good condition, a polish that simply enhances the shine and protects the finish may be sufficient. If the finish is damaged or faded, a polish with abrasives may be necessary to restore the finish.
- Desired shine: The level of shine that is desired will also influence the type of polish that should be used. Some polishes are designed to produce a high-gloss finish, while others are designed to produce a more subtle, satin finish.
- Ease of use: Consider the ease of use of the polish when selecting a product. Some polishes may be more difficult to apply or remove than others.
- Compatibility with the finish: Make sure to select a polish that is compatible with the type of finish you are working with. Using a polish that is not compatible with the finish can damage the finish or produce undesirable results.
- Environmental considerations: Some polishes may contain ingredients that can be harmful to the environment or to human health. If this is a concern, consider selecting a polish that is formulated with environmentally-friendly or non-toxic ingredients.

i. Foam fire extinguishers: Foam fire extinguishers are designed to extinguish fires that involve flammable liquids, such as gasoline, oil, or grease. They work by smothering the fire and cutting off the oxygen supply, which helps to prevent the fire from spreading. Foam fire extinguishers are usually identified by a cream or yellow color.
ii. Vaporizing liquid fire extinguishers: Vaporizing liquid fire extinguishers, also known as clean agent fire extinguishers, are designed to extinguish fires that involve electrical equipment or combustible gases. They work by releasing a fine mist of a chemical agent that absorbs heat and disrupts the chemical reaction that is causing the fire. Vaporizing liquid fire extinguishers are usually identified by a blue color.

- Ensure your own safety: Before attempting to rescue the victim, you should ensure that you are not at risk of being shocked yourself. You can do this by using a non-conductive object, such as a wooden broom handle or a rubber mat, to separate the victim from the source of electricity.
- Call for help: If the victim is unconscious or unresponsive, call for emergency medical assistance immediately.
- Disconnect the power source: If possible, and if it can be done safely, try to disconnect the power source or turn off the electricity at the main breaker. If you are unable to do this, you will need to use a non-conductive object, such as a wooden broom handle, to gently push the victim away from the source of electricity.
- Check the victim’s pulse and breathing: If the victim is unconscious, check for a pulse and start CPR if necessary. If the victim is breathing, keep their airway open and monitor their breathing.
- Treat for burns: If the victim has burns on their skin, gently remove any clothing or jewelry that may be stuck to the burn and cover the burn with a sterile, non-adhesive dressing.
- Transport the victim to a hospital: If the victim is stable, carefully transport them to a hospital for further treatment. If the victim is unconscious or experiencing severe symptoms, wait for emergency medical personnel to arrive and transport the victim to the hospit
