We can use freehand to draw a fairly straight line by the following procedures.</p> <ol> <li>Put a dash or dot far enough to the right-hand side of the paper.</li> <li>Start to draw a line from the left-hand side to join the dash or dot with your eyes fixed on the point.</li> </ol> <h3>Sketching a Curve</h3> <p>To draw a curve by freehand, it will be necessary to plot some points not too far from each other at different levels, like this --------- with the points in position attempt to draw curves by joining the dashes or dots.</p> <h3>Sketching a Circle</h3> <p>To draw circles, the easiest way is to draw lines which are equal in diameter to the circle in different directions. Each line must be as faint and straight as possible, each crossing one another at a central point. Now, join the points by little curves from the top of each line. Try to draw other circles by means of joining two large curves having half the size as radius and full size in diameter.</p> <h3>Sketching a Square Box</h3>

<h1>SAFETY GUIDELINES</h1> <p>CONTENT</p> <ol> <li>Introduction to Safety Guidelines</li> <li>Safety Guidelines for Pedestrians</li> <li>Safety Guidelines for Cyclists</li> </ol> <p> </p> <h2>Introduction to Safety Guidelines</h2> <p>Safety means protection from danger or injury. Safety guidelines are the rules to be followed in order to reduce or eliminate danger or injury. The safety of road users such as pedestrians, cyclists and motorists is highly important given the number of road accidents on roads and highways. Great importance also needs to be placed on the safety of students and their instructors in workshops in order to prevent accidents.</p> <p>Accidents are unpleasant events. They happen unexpectedly and cause injury or damage. We must plan against them by taking safety measures.</p> <p> </p> <h2>Safety Guidelines for Pedestrians</h2> <p>The following safety guidelines for pedestrians should be observed:</p> <p>1. Always walk on the left side of the road facing oncoming traffic.</p> <p>2. Where sidewalks are provided, use them rather than walking on the tarred road.</p> <p>3. Wear reflective or bright coloured clothes at night and carry a torch.</p> <p>4. When crossing the road, look left, right and left again before crossing.</p> <p>5. Walk quickly when crossing.</p> <p>6. Pedestrians should attempt to cross the road only at a safe place such as the:</p> <p>(a) Zebra crossing</p> <p>(b) Pedestrians overhead bridge</p>
