Final answer:
The statement is false; both wet and dry cement present significant hazards. Wet cement is alkaline and can cause burns, while dry cement dust poses serious respiratory risks.
Step-by-step explanation:
The statement 'Dry concrete or cement dust is not as hazardous as new wet cement because it has cured' is false. While it is true that wet cement poses certain chemical risks because it is highly alkaline, which can lead to chemical burns and dermatitis, dry cement dust is also hazardous. The hazards associated with dry cement dust include respiratory issues — inhaling the fine particles can lead to silicosis, lung cancer, and other respiratory illnesses. It is essential to acknowledge the dangers of both wet and dry cement and use proper safety precautions such as personal protective equipment when working with them.
