What is the recommended horizontal spacing for a ladder placed vertically against a wall?

1 foot for every 2 feet vertical
1 foot for every 3 feet vertical
1 foot for every 4 feet vertical
1 foot for every 5 feet vertical

The correct answer is: 1 foot for every 4 feet vertical

The recommended horizontal spacing for a ladder when placed vertically against a wall is indeed 1 foot for every 4 feet of vertical height. This guideline is critical for ensuring the ladder is positioned at a safe angle, which enhances stability and reduces the risk of accidents while climbing. Maintaining this spacing means that if you're using a ladder that reaches a height of 12 feet, it should be placed 3 feet away from the wall (since 12 feet divided by 4 equals 3 feet). This angle of placement allows for safer access and egress when working at heights, as it helps to prevent the ladder from slipping or tipping over, which are common hazards associated with improper ladder usage. Following this spacing guideline is consistent with OSHA recommendations and general safety practices in construction, emphasizing the importance of safety for workers when using ladders.
