To ensure safety from electrical hazards in construction, several key practices and requirements should be followed:

1. Use of Protective Equipment: Employees working near exposed energized parts must use protective shields, barriers, or insulating materials to prevent accidental contact and protect against shock, burns, or other injuries [1].

2. Alerting Techniques: Safety signs, symbols, or accident prevention tags should be used to warn employees about electrical hazards. Barricades should be used to prevent access to areas with uninsulated energized conductors [1].

3. Personal Protective Equipment (PPE): Employees must be provided with appropriate electrical protective equipment, such as insulated gloves and nonconductive head protection, to protect against potential electrical hazards [2].

4. Handling Conductive Materials: Conductive materials and equipment should be handled in a way that prevents contact with exposed energized conductors. This includes using insulation, guarding, and proper material handling techniques [3].

5. Portable Ladders: When used near exposed energized parts, portable ladders must have nonconductive siderails to prevent electrical contact [3].

6. Housekeeping and Maintenance: Employees should not perform housekeeping duties near live parts unless adequate safeguards are provided. Additionally, all electrical equipment should be maintained in proper working condition and tested according to the manufacturer's recommendations [3].

7. Confined Spaces: In confined or enclosed spaces containing exposed energized parts, protective shields, barriers, or insulating materials must be used to avoid inadvertent contact [3].

By adhering to these guidelines, construction sites can significantly reduce the risk of electrical hazards and ensure a safer working environment for all employees.
