Which of the following is covered under the OSHA Worker Protection Standards law?

The correct answer is that multiple horticultural operations, including planting and maintenance, are covered under the OSHA Worker Protection Standards law. This law is designed to ensure the safety and health of workers in agricultural environments, specifically those who handle pesticides and may be exposed to harmful chemicals during various horticultural practices.

The Worker Protection Standards are comprehensive and recognize that workers in the horticultural sector engage in a variety of tasks, including planting, maintaining, and harvesting crops. These standards establish requirements for training, safety equipment, and access to information about the pesticides used in these operations. By covering a broad range of horticultural activities, the law aims to protect workers from the risks associated with pesticide exposure and to promote safe working conditions across multiple aspects of the horticulture industry.

In contrast, the other options could imply a more limited scope of coverage. Only horticultural services and sales, or just retail sales and landscaping, may not encompass the full array of activities and potential hazards that workers face in more comprehensive horticultural settings. The focus of the OSHA regulations is on protecting workers engaged in agricultural operations, hence the inclusion of diverse horticultural tasks under this law.
