Seasonal Transition Hazards (Spring/Fall)
Construction and general industry · Ver en español
Talking points
- Spring and fall bring freeze-thaw cycles that create ice on surfaces that were dry the day before. Morning frost on steel, scaffolding planks, and ladders is a slip hazard that melts by mid-morning.
- Temperature swings of 30-40°F within a single day mean the PPE and clothing you need at 7 AM is wrong by noon. Layer so you can adjust without sacrificing safety.
- Wet conditions in spring increase the risk of unstable soil in excavations and on slopes. Re-inspect protective systems after any freeze-thaw cycle or rain event.
- Changing daylight hours affect visibility during early morning and late afternoon work. Adjust task lighting and high-visibility clothing as days shorten in fall.
- Seasonal allergies can impair concentration and are worsened by construction dust. Workers on antihistamines may experience drowsiness that affects their performance at height or around machinery.
Ask the crew
What seasonal conditions should we be watching for this week — and do we need to adjust our plan?
