  • 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

  • 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:

    • Cable
    • Bracket
    • GI Wire
    • Elbow
    • Bend
    • PVC circular box
    • Rowel plug
    • Saddle
    • Screw
    • Tube light
    • Cable lugs
    • Cable tie
    • Insulating clip
    • Flexible conduit
    • Electric soldering lead
    • Copper plate
    • Copper sheet
    • Bare copper conductor
    • Plastic tape

  • fittings

    Electrical fittings means electric lines, fittings, apparatus and appliances de- signed for use by consumers of electricity for lighting, heating, motive power and other purposes for which electricity can be used. These can include a wide range of fittings such as below:

    • Switch
    • Switch box
    • Fuse
    • Regulator

  • drawings

    An electrical drawing is a type of technical drawing that shows information about power, lighting, and communication for an engineering or architectural project.

    • Technical drawings
    • Sketch

  • specifications

    Electrical Specifications means the specifications and requirements for electrical service to the Site.

    • Product specifications
    • Material types
    • Standards of work
    • Tolerances
    • Treatments and finishes

  • sign and symbols

    Electrical signs and symbols provide workers and others with information on electrical hazards and instructions on preventing harm. Labels, such as those used in PAT testing, inform people that electrical equipment and appliances are safe to use or not.
