Final answer:
Kerry needs to use toeboards that meet safety requirements to prevent falling objects from the scaffolding and must take safety precautions to prevent accidents, including not leaning too far over guardrails and keeping hazardous materials secure.
Step-by-step explanation:
Kerry is a commercial painter who is aware of the falling object hazard she creates by keeping paint and supplies on the scaffolding platform. To mitigate this risk, she plans to use toeboards which must meet specific safety requirements. These toeboards should be able to withstand at least a force of 10 pounds, have a minimum height of 3.5 inches from the platform, have a clearance of ¼ inch or less from the working surface, and extend sufficiently to protect workers on lower levels.
In the scenario provided, Kerry must also take precautions not to drop items from the scaffolding, be aware of her surroundings, and make sure she does not lean too far over the guardrails, which could lead to accidents. Moreover, ensuring that paint, paint remover, and other flammable liquids are kept out of reach of unauthorized personnel is essential for preventing accidents, as illustrated in the counter example situation provided.
