The tool shown in the figure is called a scriber. A scriber is a pointed instrument used for marking or scoring lines on surfaces, particularly metal or wood. It typically has a sharp, hardened steel point that can be adjusted for depth and is held like a pen or pencil. The scriber is commonly used in metalworking, carpentry, and other trades for tasks such as marking measurements, scribing arcs or circles, or creating reference lines for cutting or shaping materials.

The correct answer is Industrial Training Institute. ITI stands for Industrial Training Institute, which is a government-run training institute in India that offers technical and vocational training programs in various trades. These institutes provide practical training to students and help them develop skills required for specific industries.

The correct answer is pipe vice. The type of vice shown in the figure is a pipe vice. This can be determined by examining the design and features of the vice, such as the presence of a curved jaw that is specifically designed to hold pipes securely. Additionally, the size and shape of the vice also indicate that it is suitable for holding pipes of different diameters. Therefore, based on these observations, it can be concluded that the type of vice shown in the figure is a pipe vice.

The correct answer is green because green is commonly used as the colour code bin for glass wastage. This helps in efficient waste management and recycling processes as different colours are assigned to different types of waste materials. Green bins are specifically designated for glass waste, making it easier for individuals to dispose of glass in the appropriate bin and for waste management systems to separate and recycle glass effectively.

Class A fires are fires that involve ordinary combustible materials such as wood, paper, cloth, and plastics. These materials burn at relatively low temperatures and leave behind ash. Class A fires can be extinguished with water, foam, or dry chemical extinguishers.

NIMI (National Instructional Media Institute) is the institute that develops training course materials for ITI's (Industrial Training Institutes).

Safety shoes with steel toe caps are designed to protect the feet in a workshop environment. The steel toe caps provide an additional layer of protection for the toes, preventing injuries from heavy objects or equipment falling onto the feet. Leather, canvas, and rubber shoes may not offer the same level of protection as safety shoes with steel toe caps. Therefore, safety shoes with steel toe caps are the most suitable option for ensuring foot safety in a workshop setting.

The figure is likely showing a symmetrical shape with a point or feature at its center. A center datum is a reference point or feature used to establish and control the position and orientation of other features in a part or assembly. It is commonly used when designing objects with rotational symmetry, where the center is a critical point for alignment and measurement.

The correct answer is "centre punch 90°". A centre punch is a tool used to make an indentation in a workpiece to mark the centre for drilling. The 90° angle refers to the angle of the tip of the centre punch, which is typically 90 degrees. This angle helps to guide the drill bit accurately into the centre of the marked indentation. Therefore, the centre punch with a 90° angle is used to locate the drill centre.

A try square is a tool used in woodworking and metalworking to check the squareness and flatness of a workpiece. It consists of a ruler and a handle at a right angle to each other. By placing the ruler against the edge of the workpiece and ensuring it is perpendicular, the try square can determine if the workpiece is square or if it has any deviations from a flat surface. Therefore, the correct answer is that a try square is used to check both squareness and flatness.

Only a qualified person should attend electrical work because working with electricity can be dangerous and requires specialized knowledge and training. Unskilled and unqualified individuals may not have the necessary skills or understanding to safely handle electrical systems, which could result in accidents, injuries, or damage to property. A semiskilled person may have some knowledge but may not have the expertise to handle more complex electrical tasks. Therefore, it is crucial to have a qualified person who has the proper training and experience to ensure the work is done safely and correctly.

Explosive is the correct answer because chemical hazards refer to substances that can cause harm or damage through chemical reactions. Explosives are substances that undergo rapid chemical reactions, resulting in the release of large amounts of energy, heat, and gas. They can cause explosions, fires, and other hazardous situations, making them a clear example of a chemical hazard. Fungi, fatigue, and vibration are not chemical hazards as they do not involve chemical reactions or the release of harmful substances.

A pin vice is a small handheld tool used for holding small diameter jobs securely in place. It consists of a handle with a collet at one end that can be tightened to grip small objects such as pins, wires, or small drill bits. This allows for precise control and stability when working on delicate or intricate tasks that require a firm grip on small objects.

Vice clamps have the advantage of protecting the work surface from damage. When clamping materials, vice clamps provide a secure grip without causing any harm or leaving marks on the surface. This is particularly important when working with delicate or sensitive materials that could be easily scratched or dented. By using vice clamps, the work surface remains intact and undamaged, ensuring a professional and high-quality finish to the job.

The indication of the sign "give away" suggests that there is something being offered or given for free. It could be a promotion, a gift, or a charitable act where something is being given without any cost or expectation in return. This sign is commonly used to attract attention and inform people about a generous offer or opportunity.

The correct answer is "Spring joint outside caliper." This type of caliper has a spring joint on the outside, which allows for easy adjustment and measurement. The spring joint provides flexibility and ensures accurate readings.

The correct answer is "hard jaws" because the part marked 'x' is referring to the jaws of a tool or machine. In this case, the jaws are specifically referred to as "hard jaws" which indicates that they are made of a hard material such as steel and are designed to securely grip or hold objects in place.

The tool shown in the figure is an odd leg caliper. This type of caliper is used to measure the distance between two opposite sides of an object. It consists of two legs, one fixed and one movable, with a scale or vernier for precise measurements. The odd leg caliper is commonly used in woodworking, metalworking, and engineering applications.

Physiological hazards refer to hazards that can cause harm to the physical health and well-being of individuals. This can include hazards such as exposure to extreme temperatures, noise, radiation, and infectious diseases. In the context of sickness, physiological hazards are relevant as they can cause various illnesses and health issues. Therefore, the correct answer, physiological, accurately represents the hazard associated with sickness.

The correct answer is ORGANIZATION. This means that the responsibility for safety lies with the organization as a whole. It is the organization's duty to ensure that proper safety measures are in place, provide training and resources to employees, and create a culture of safety. This includes implementing safety policies and procedures, conducting regular inspections, and addressing any safety concerns or hazards. By taking responsibility for safety, the organization can create a safe and healthy work environment for everyone involved.
