What is the main hazard associated with allowing wet concrete to touch the skin?

Allowing wet concrete to touch the skin presents significant hazards due to its chemical composition. Fresh concrete contains cement, which is highly alkaline and can cause various skin irritations and even serious burns. This is primarily because, when fresh concrete cures, the pH levels can rise to around 12 to 13, which is caustic and can lead to severe chemical burns on prolonged contact.

While some might assume that wet concrete is harmless, in reality, it poses serious risks, particularly if left on the skin for an extended period. If it dries on the skin, it can result in dermatitis or more severe injuries requiring medical attention. This makes the hazard associated with wet concrete not only about physical irritation but also about the potential for more significant skin damage. The emphasis on safety when handling concrete is critical for preventing skin injuries, which underscores the need for appropriate protective measures, such as gloves and long sleeves, when working with wet concrete surfaces.
