1.5 Construction Safety Standards- Hand And Power Tools

Hand tool injuries are usually caused by misuse and improper maintenance. This statement is true because when hand tools are not used correctly or are not maintained properly, they can become dangerous and cause injuries. Misuse can include using the tool for a purpose it was not designed for or using it in an incorrect manner. Improper maintenance can lead to tools becoming dull, rusty, or damaged, increasing the risk of accidents. Therefore, it is important to use hand tools correctly and regularly maintain them to prevent injuries.

It is necessary for the manufacturer to mark the rated capacity on all jacks. This marking is important because it provides information about the maximum weight that the jack can safely lift or support. It helps users to determine whether the jack is suitable for their intended use and prevents overloading, which can lead to accidents or damage. Therefore, it is true that the manufacturer's rated capacity must be marked on all jacks.

Using an electrical cord to hoist a tool up a ladder is not okay because electrical cords are not designed or intended for lifting heavy objects. They may not have the necessary strength or durability to support the weight, which can lead to the cord breaking or snapping, causing the tool to fall and potentially causing injury or damage. It is important to use the appropriate equipment, such as a rope or pulley system, that is specifically designed for lifting and hoisting tasks.

Machine guards must protect the operator and others from various hazards, including the point of operation or cutting point, in-running pinch points, rotating parts, and flying chips and sparks. These hazards pose significant risks to safety and can cause serious injuries if not properly protected against. Therefore, it is essential for machine guards to cover all of these potential dangers to ensure the safety of the operator and others in the vicinity of the machine.

The correct answer is "All the above" because all of the listed options are basic tool safety rules. To ensure safety while using tools, it is important to maintain them in a safe condition, use the appropriate tool for the job, inspect them before each use, and use the right personal protective equipment (PPE). By following these rules, the risk of accidents and injuries can be minimized.

This statement suggests that Jacks must have a stop indicator that should not be surpassed. In other words, there is a maximum limit or boundary that should not be crossed. Therefore, the correct answer is True, indicating that it is necessary for Jacks to have a stop indicator that should not be exceeded.

The correct answer is "All of the above". This means that when using powder-actuated tools, you must test the tool each day before loading to ensure the safety devices are working properly, wear suitable ear, eye, and face protection, select a powder level that will do the work without excessive force, and obtain appropriate training from a certified trainer, such as a Hilti representative. All of these measures are necessary to ensure the safe and proper use of powder-actuated tools.

Whip checks and pins are required at every connection including the source connection, tool connection, and intermediate connections on a pneumatic hose. This is because whip checks and pins are safety devices that help prevent the hose from whipping or flailing in the event of a sudden release of pressure or failure at any connection point. By securing the hose at every connection, the risk of injury or damage caused by a whipping hose is minimized.

The correct answer is that when using a jack, you want to make sure that the base is on a firm, level surface, it is centered under load, the jack head is placed against a level surface, and to lubricate and inspect jacks regularly. This is important for safety and efficiency when using a jack. A firm and level surface ensures stability and prevents the jack from tipping over. Centering the jack under the load distributes the weight evenly and prevents accidents. Placing the jack head against a level surface ensures proper contact and support. Regular lubrication and inspection help maintain the jack's functionality and identify any potential issues.
