High Voltage Lines Checklist (Taken from the "Tailgate Meetings that Work : A Guide to Effective Construction Safety Training" series)

• Check the box if the statement is true.
• Fill in the blanks where the appears.
  
  
• Citations in brackets are from Title 8 of the California Administrative Code.

HAZARD IDENTIFICATION

• The company has a written Injury and Illness Prevention Program (IIPP) that meets all Cal/OSHA requirements. It includes identification of high voltage electrical hazards on the site, regular inspections, accident investigation, and correction of hazardous conditions. [1509]

NOTIFICATION AND RESPONSIBILITY

• Before any work begins within the minimum clearance distance of an overhead high voltage electrical line, the owner/operator of the line is notified. (See page 2 for clearance distances.) [2948]
  
• Any overhead line is considered energized unless the owner verifies it is not energized and the line is visibly grounded. [2946(d)]
  
• Work near energized overhead lines is done only by qualified persons unless steps are taken to guard against accidental contact. [2320.1(b)]

• There are signs in plain view on all cranes, derricks, power shovels, pile drivers, and similar machinery, reading as shown below: [2947]
  
  
  • Unlawful to Operate This Equipment Within 10 Feet of High Voltage Lines of 50,000 Volts or Less. [2947]
    
    
  • For Minimum Clearances of High Voltage Lines in Excess of 50,000 Volts, See California Code of Regulations, Title 8, Article 37, High Voltage Electrical Safety Orders.

MINIMUM CLEARANCE

• Unless an overhead high voltage electrical line is de-energized and visibly grounded, nothing comes within the minimum clearance distance at any time: [2946(b)(2) and (3)]
  

[2946, Table 1 and Table 2]

Use the table on the previous page to determine required minimum clearances on this job site. If voltages are different on different parts of the site, list them separately for each area.

• Tools, machinery, equipment, supplies, materials, or apparatus are stored beyond the required clearance distance from overhead high voltage electrical lines. [2946(b)(4)]
  
• Workers and/or their equipment or materials are never over or above an energized overhead high voltage electrical line. [2946(b)(1)] (For tower crane exceptions see [2946(b)(1)(B).])
  
• Calculation of clearance distances from overhead high voltage lines takes into account possible line movement due to strains on the supporting structures or attachments. [2946(c)]
  

• Workers exposed to possible electric shock are provided and use suitable protective equipment or devices, such as insulated rubber gloves. [1518]
  
• Workers exposed to possible electric shock or burns are provided and use approved head protection. For under 600 volts, head protection meets the requirements for Class A or B in American National Standards Institute (ANSI) standard Z 89.1 1986, Requirements for Protective Headwear for Industrial Workers. For over 600 volts, head protection meets the requirements for Class B. [3381(b) and (d)]
  
• First aid equipment is available. There are personnel trained in first aid on-site. The site also has an effective communications system for contacting help. [1512(b), (c), and (e)]
