Oregon Construction Contractors (CCB) Practice Test

Which of the following is a common non-hazardous waste generated at construction sites?

1. Concrete

2. Roof coverings

3. Hazardous chemicals

4. Wood pallets

The correct answer is: Roof coverings

The reasoning behind identifying roof coverings as a common non-hazardous waste generated at construction sites lies in their composition and typical handling practices. Roof coverings often consist of materials such as asphalt shingles, metal sheets, or synthetic membranes, which, when disposed of, do not typically introduce hazardous substances into the environment. In the context of construction waste, it is vital to distinguish between hazardous and non-hazardous materials. Non-hazardous construction debris is often reusable or recyclable, while hazardous materials can pose significant environmental and health risks. Although wood pallets can also be categorized as non-hazardous waste, they are less prevalent than roof coverings in terms of volume generated at construction sites. Concrete, while commonly generated, can sometimes present challenges if it contains additives or contaminants. Hazardous chemicals, as the name implies, involve substances that require special handling and disposal due to their potential danger. Understanding the classifications of construction waste is important for compliance with environmental regulations and responsible waste management practices.
