Which of the following is considered a common safety hazard in child care facilities?

In child care facilities, one of the most significant safety hazards is the presence of poisonous substances. These substances can include household cleaners, medications, plants, and various chemicals that are often found in environments where children are present. Young children are naturally curious and may not recognize the dangers of these substances, making it crucial for child care providers to take proactive measures to ensure that such items are stored out of reach, properly labeled, and secured in child-proof containers.

The other options represent safer practices or items that contribute positively to a child care environment. Safe sleep environments and highly supervised playgrounds are essential components of a healthy child care setting, focusing on preventing harm. Educational toys are designed to engage children in learning while ensuring they are safe for use. Therefore, while a safe environment is created by practices and materials aimed at promoting wellness, the presence of poisonous substances stands out as a clear and prevalent safety hazard that requires vigilant prevention strategies.
