    1. Risk assessment: Employers are required to assess the risks to the safety and health of their employees, including the risks posed by the work environment, the equipment and machinery used, and the substances and materials handled. Based on this assessment, employers must implement appropriate measures to control and mitigate these risks.
    2. Safe systems of work: Employers must establish and maintain safe systems of work, including procedures, policies, and practices, to ensure the safety and health of their employees. This may include the provision of personal protective equipment, training and instruction, and emergency procedures.
    3. Maintenance of machinery and equipment: Employers must ensure that all machinery and equipment used in the workplace is regularly maintained and kept in good working order, and that any defects are promptly repaired.
    4. Reporting of accidents and incidents: Employers must report any accidents or incidents that occur at the workplace to the appropriate authorities and keep records of these incidents.
    5. Health and safety training: Employers must provide adequate training and instruction to their employees on health and safety matters, including the risks associated with their work and the measures in place to control and mitigate these risks.
    6. Cooperation with safety and health authorities: Employers must cooperate with safety and health authorities, including by providing access to the workplace and relevant information, and by complying with any orders or instructions issued by these authorities.

    conditions upon which a person can get an electric shock.

    Jemshah Enlightened

    Contact with live electrical wires or appliances: If a person touches a live electrical wire or an appliance that is connected to a live electrical source, they can receive an electric shock. This can happen if a person accidentally touches a live wire or if they intentionally try to tamper with anRead more

    1. Contact with live electrical wires or appliances: If a person touches a live electrical wire or an appliance that is connected to a live electrical source, they can receive an electric shock. This can happen if a person accidentally touches a live wire or if they intentionally try to tamper with an electrical appliance or system.
    2. Contact with water: Water is a conductor of electricity, and if a person comes into contact with water while handling electrical appliances or wires, they may receive an electric shock. This is particularly dangerous if the person is standing on a wet surface or if the water is in contact with a live electrical source.
    3. Contact with metal objects: Metal objects, such as jewelry or metal tools, can conduct electricity and can cause an electric shock if they come into contact with live electrical wires or appliances.
    4. Improper use of electrical equipment: Using electrical equipment improperly, such as by not following proper safety procedures or by using damaged or defective equipment, can also increase the risk of an electric shock.

    describe the two techniques of filling

    Jemshah Enlightened

    Filling with a solid material: This technique involves the use of a solid material, such as a paste, putty, or compound, to fill in gaps, cracks, or imperfections in a surface. The filling material is typically applied using a spatula, knife, or other tool, and is then smoothed or shaped to match thRead more

    1. Filling with a solid material: This technique involves the use of a solid material, such as a paste, putty, or compound, to fill in gaps, cracks, or imperfections in a surface. The filling material is typically applied using a spatula, knife, or other tool, and is then smoothed or shaped to match the surrounding surface.
    2. Filling with a liquid material: This technique involves the use of a liquid material, such as a paint, resin, or epoxy, to fill in gaps, cracks, or imperfections in a surface. The liquid filling material is typically applied using a brush, roller, or spray gun, and is then allowed to dry or cure to form a solid mass. This technique is often used to repair or reinforce structural components or to provide a smooth and seamless finish to a surface.

    Lacquering and enamelling are two different types of finishing processes that are used to protect and decorate the surface of a variety of products, including metal, wood, and plastic. Here are some key differences between the two processes:

    1. Materials used: Lacquering involves the application of a thin, protective layer of lacquer, which is a type of clear or colored resin, to the surface of a product. Enamelling, on the other hand, involves the application of a layer of enamel, which is a type of glassy material that is fused to the surface of a product at high temperatures.
    2. Application process: Lacquering is typically done by spraying, brushing, or rolling on the lacquer, while enamelling involves the use of a furnace or kiln to heat the enamel to the point of melting, after which it is applied to the surface of the product and allowed to cool and harden.
    3. Durability and scratch resistance: Enamel is generally more durable and scratch-resistant than lacquer, as it forms a harder and more durable surface layer on the product. However, enamel is also more brittle and prone to chipping or cracking than lacquer, which can be more flexible and resistant to impact.
    4. Aesthetics: Lacquer can be applied in a range of colors and finishes, from gloss to matte, and is often used to enhance the appearance of the product by adding a glossy or lustrous finish. Enamel, on the other hand, is typically used to provide a smooth, glossy, and colorful finish to the product, and is often used in decorative and functional applications, such as on cookware and appliances.

    explain i. hardness ii. malleability properties of engineering materials

    Best Answer
    Jemshah Enlightened

    i. Hardness is a measure of a material's resistance to deformation, indentation, and scratching. It is an important property of engineering materials because it determines the material's ability to withstand wear and tear and to maintain its shape and dimensional accuracy under load.

    i. Hardness is a measure of a material’s resistance to deformation, indentation, and scratching. It is an important property of engineering materials because it determines the material’s ability to withstand wear and tear and to maintain its shape and dimensional accuracy under load. Hard materials are often used for cutting and wear-resistant applications, while softer materials may be more suitable for applications that require flexibility or shock absorption.

    ii. Malleability is a measure of a material’s ability to be deformed or shaped without breaking or cracking. Materials that are highly malleable can be easily formed or shaped by hammering, rolling, or pressing, while materials that are not very malleable are more brittle and tend to break or crack under these types of deformations. Malleability is an important property of engineering materials because it determines the material’s suitability for certain manufacturing processes, such as forging or stamping. Materials that are highly malleable are often used in the manufacturing of parts that require precise shapes or intricate details, such as jewelry or coins.
