These are tools which are used manually. This includes tools like screwdrivers, hammers, pliers, wrenches, etc. They are generally smaller, lighter, and easy to carry around.

These tools require an external power source, such as electricity or gas, to function. They are typically used for heavier tasks like drilling, sawing, sanding, etc. Examples include drills, saws, sanders, etc.

These are the basic rules that should be followed to ensure safety while using hand and power tools. Some of them are the right tools should be chosen for the job, all tools should be properly maintained, appropriate work attire should be worn to ensure safety, and appropriate workspace is available. Always read and understand the instructions manual of the tool you are using.

This refers to the best practices that must be followed when using hand and power tools to ensure safety. Some include regular inspection of tools before starting work, using the correct tools for the job, wearing appropriate safety gear, and using the tool as designed.

These are best practices that should be followed while using hand tools like screwdrivers, hammers, pliers, wrenches, etc. They involve inspecting tools before using them, ensuring the tools are in proper working condition, not using the tool for an improper purpose, and ensuring the tools are correctly stored.

These are the goals or objectives that a learner is expected to achieve after completing a particular course or training. It is important to understand the objectives to know what to expect to learn.

This is a common part of our everyday lives and is present in nearly every industry. They help use perform tasks easier.

Tools can be dangerous if used improperly. They have the potential to cause severe injuries. Therefore, it is important to use tools safely by understanding basic safety practices and following best practices.

Wire rope slings are strong and flexible, making them suitable for most crane lifting tasks. They are preferred over fiber line or chain slings due to their versatility.

Fiber line slings offer flexibility and protect delicate surfaces better than wire rope. However, they're less strong and susceptible to damage from sharp edges.

Chain slings are ideal for heavy steel objects like rails, pipes, and beams. They're also suited for hot loads or loads with sharp edges that could damage other sling types.

Hooks are used to attach slings to objects, while shackles are used for loads too heavy for hooks. Both need regular inspection for damage.

Screwdrivers are hardened steel tools with various sizes and shapes, used to turn screws with slotted heads.

Materials that allow electricity to flow easily through them, like metals.

A sudden and unintended flow of electrical current through the body.

The danger of electric shock caused by contact with live electrical components.

An uncontrolled release of electrical energy, often accompanied by a bright flash and loud bang.

A system that provides both normal and essential power to operating units. It often includes dual DC supplies, UPS, and transformers.

A fire caused by an electrical fault, overheating, or short circuit.

An uninterruptible power supply (UPS) provides backup power in case of a power outage. It guarantees a continuous and stable power supply.

A sudden and violent explosion caused by an electrical arc flash.

Measures taken to prevent electric shock and fires, such as using insulation, grounding, and circuit breakers.

Direct current (DC) power is used for many industrial processes and control systems. Dual DC supplies provide redundancy by ensuring that even if one supply fails, the other can keep the system running.

A transformer converts high-voltage electricity to a lower voltage needed by the equipment in a plant.

The ability to control the flow of electricity, prevent shocks, and protect equipment.

The instrument signal ground is a separate ground that is insulated from the rest of the system and used for sensitive electronic signals. This ensures a clean signal path.

The minimum amount of electricity a person can feel, typically around 1 milliampere (mA).

A dangerous electrical current that can cause the heart to stop beating rhythmically, potentially leading to death.

An electric shock that results in death.

A type of injury caused by excessive heat from electricity passing through the body.

The amount of electrical current flowing through a circuit, measured in Amperes (A).

The force that pushes electrical current through a circuit, measured in Volts (V).

The path that electricity takes from a power source to a load and back.

A decrease in the perception of electric shock as the frequency of the current increases.

The amount of electric current flowing through a body, measured in amperes (A) or milliamperes (mA).

The opposition to electric current flow, measured in ohms (Ω).

A condition where the heart's rhythm becomes chaotic and ineffective, often caused by an electric shock.

The duration of an electric shock, which significantly impacts its severity and likelihood of causing ventricular fibrillation.

A simple equation that states the relationship between current (I), voltage (V), and resistance (R): I = V/R.

The point at which a person can no longer release their grip on an electrified object due to muscular contractions.

A process by which an electrical shock can lead to death, often due to ventricular fibrillation.

Alternating current (AC) is more dangerous than direct current (DC) because it causes muscle contractions called tetany, which can hold someone in contact with the current, prolonging exposure. Low frequency AC (50-60 Hz) is more dangerous than high frequency AC or DC of the same voltage and amperage. AC also has a higher tendency to cause ventricular fibrillation which can lead to death.

AC has a greater tendency to throw the heart's pacemaker neurons into a condition of fibrillation, which is a chaotic and irregular heart rhythm. DC, on the other hand, is more likely to cause the heart to stop completely (asystole).

Defibrillators, used by emergency personnel, deliver a DC shock to the heart, stopping fibrillation and giving the heart a chance to regain a regular beat.

The human body acts as a resistor to the flow of electric current. Wet skin has a significantly lower resistance than dry skin, making it easier for electricity to flow through the body.

Electric currents passing through the body can cause severe burns due to the heat generated by electrical resistance. This is why it's crucial to avoid contact with electricity, especially when wet.
