Which of the following is a common safety practice when using ladders on a job site?

Maintaining three points of contact whenever possible is a fundamental safety practice when using ladders on a job site. This method enhances stability and minimizes the risk of falling by ensuring that two hands and one foot, or two feet and one hand, are always in contact with the ladder. This creates a secure balance and allows the user to maintain control while climbing or descending, even in situations where sudden movements or shifting might occur.

The importance of this practice cannot be overstated, as falls from ladders are a significant cause of injuries in the workplace. By adhering to the principle of maintaining three points of contact, electricians and other workers can significantly reduce their risk of accidents and ensure a safer working environment.
