Toolbox Talk: Electrical Safety for Construction Job Sites
Guide for Discussion: It doesn’t take a lot of electricity to kill you. The amount of current needed to light an ordinary 60-watt light bulb is five times what can kill a person. Thus, all electrical equipment on a construction site is potentially deadly.
Electrical extension cords are numerous on construction sites and become damaged because of the rough conditions in which they are used.
Inspect to ensure:
- All extension cords are three-wire cords
- The ground pin is on a male plug
- All cords are protected from damage likely to occur when passing through a door or window
- Metal boxes with knockouts are not used on extension cords
- ROMEX (non-metallic sheathed cable) is not used as flexible cord
- Cords are not stapled or hung from nails
Also, check these items:
- Temporary lights are not supported by cords
- Bulb guards are used on temporary lights
- Electrical power tools with non-dead man switches have a magnetic restart (when injury to the operator might result if motors were to restart following power failures)
- Provisions are made to prevent machines in place from automatically re-starting upon restoration of power
- Outlets do not have reversed polarity
- Power tools are double insulated or have a ground pin
Guard all of exposed electric of more than 50 volts so no one can come in contact (receptacles, light-bulb sockets, bare wires, load center, switches, etc.).
- Using approved enclosures
- Locate them in a room, vault or similar enclosure accessible only by qualified persons
- Arrange suitable permanent, substantial partitions, or screens so only qualified persons have access to the space within reach of live/energized parts
- Locate them on a suitable balcony or platform that is elevated and arranged to exclude unqualified persons
- Elevate them 8 feet or more above the working surface
Note: Always promote a discussion on any of the topics covered in the Toolbox Talk!
Intention: At Construct Corps we strive to nurture a “safety culture.” The intention of the Construct Corps Tool Box Talk is a brief safety talk or meeting about a specific subject given once weekly. It can take a lot of time to develop safety topics for such tool box talks each week. Feel free to print and distribute these talks.
For questions about Toolbox Talk or general safety, contact our OSHA Authorized Instructor, Marcos Caballero at (813) 498-0359.
