It is protection from risk of harm or injury. It is also protection against damage to machines, tools as well as the prevention or removal of factors that can lead to accident. Safety must be ensured in the workshop.</p> <p>A<strong> workshop</strong> is a place where technical and engineering works are carried out.</p> <p><strong>Workshop safety</strong> is protection from risk of harm or injury to humans or damage to machines and tools in the workshop.</p> <p> </p> <h2>Meaning of Workshop Accident</h2> <p>An accident is an unexpected event resulting in injury, illness or death as well as damage to property. Accident occurs as a result of hazards. Hazard is both an unsafe condition and unsafe act. It makes an accident to occur. Hazard is, therefore, any activity, situation or substance that causes harm or injury to someone in a workshop while he/she is working.</p> <p> </p> <h2>Causes of Workshop Accident</h2> <p>The basic causes of accidents are unsafe conditions of machinery, equipment, or surroundings, and the unsafe actions of persons that are caused by ignorance or neglect of safety principles.</p> <p>The following are the causes of workshop accidents:</p> <ol> <li>Lack of safety devices.</li> <li>Failure to use safety devices provided.</li> <li>Failure to follow laid-down methods for handling tools, equipment and machines.</li>

Obedience: Pupils must obey the instructions of their teachers at all times 2. Humility: Show respect to everybody and when you are in doubt about anything, ask question. 3. Fiddling: Never play with any tool, equipment and machine in the workshop, such as ‘’ON/OFF’’ switch. 4. Horseplay: Do not run around in the workshop. Always, be patient and never rush. 5. Negligence: Report any fault or injury to your teacher, no matter how small. <h2><strong>General Safety Precautions in Workshops</strong></h2>

<h1><strong>PROPERTIES OF METALS</strong></h1> CONTENT <ol> <li>The Definition of Metals</li> <li>Identification of Metals by Physical Properties</li> <li>Classification of Metals</li> </ol>   <h2><strong>The Definition of Metals</strong></h2> A metal is a material (a compound, element or alloy) that is hard when in solid state, opaque, shiny, and which is a good conductor of heat and electricity. <h2><strong>Identification of Metals by Physical Properties</strong></h2> Identification of metals can be defined as a method used to differentiate one particular type of metal from another and from other materials which are non-metals. Metals can be identified through their properties, which include: <ol> <li>Density: This is the weight of a metal and it varies from metal to metal. E.g. aluminum is light and lead is heavy in weight.</li> <li>Colour/Lustre: This is the appearance of a metal when the surface is polished. For example, when polished and examined under a microscope, copper presents a different appearance from polished mild steel.</li> <li>Fusibility: This is the property of a metal which makes it melt and join with other metals while in a liquid form.</li>
