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>
Driving and Boring Tools
<h1>DRIVING AND BORING TOOLS</h1> <p>CONTENT</p> <ol> <li>Driving Tools</li> <li>Boring Tools</li> </ol> <p> </p> <h2>Driving Tools</h2> <p>Driving tools are used to fix nails and screws into wooden and metal materials. Nails are the iron material with a flat head, smooth stem and sharp end. Screws look like nails but they have turned or twisted stem. Screws are driven into wood with screwdrivers while nails are driven into wood and metals with the use of hammers. Hammers are driving tools that have two parts – a head, which is made of iron and a wooden handle. There are five types of hammers named according to the shape of the head. They are;</p> <p>1. Ball peen hammer.</p> <p>2. Straight peen hammer</p> <p>3. Cross peen hammer</p> <p>4. Planishing hammer</p> <p>5. Blocking head hammer</p> <p>6. Upholstery hammer</p> <p>(i) Straight-peen hammer is used for riveting while other end is used for shaping sheet metals.</p> <p>(ii) Ball-peen hammer is used for general purposes.</p>
