  • p.p.e.-personal protective equipment

    Personal Protective Equipment, commonly referred to as "PPE", is equipment worn to minimize exposure to hazards that cause serious workplace injuries and illnesses. These injuries and illnesses may result from contact with chemical, radiological, physical, electrical, mechanical, or other workplace hazards. Personal Protective Equipment may include items such as below:

    • Helmet
    • Safety goggles
    • Mask
    • Apron
    • Hand gloves
    • Safety shoe

  • tools

    Electrical tools are tools used to work on an electrical system. These can include a wide range of tools such as below:

    • Hammer
    • Cutting pliers
    • Combination pliers
    • Wire striper
    • Neon tester
    • Screw driver (flat, star and connecting)
    • Electrician knife

  • equipment

    The set of articles or physical resources serving to equip a person or thing. These can include a wide range of equipment such as below:

    • Ammeter
    • Volt meter
    • Watt meter
    • Energy meter, Single Phase and Three Phase(Analog & Digital)
    • Multi meter
    • Calculator

  • materials

    Electrical Material is basically the parts or elements used in the making of any electrical construction project. These can include a wide range of materials such as below:

    • Water pump
