Final answer:
Scaffold users must be trained about the hazards in a laboratory setting, including sharp objects, chemicals, heat, and electricity.
Step-by-step explanation:
In a laboratory setting, there are several hazards that scaffold users must be trained about. These hazards include sharp objects, chemicals, heat, and electricity. It is important for scaffold users to know how to handle these hazards safely and follow the necessary safety guidelines.
For example, when working with sharp objects, scaffold users should be aware of proper handling techniques to avoid injuries. When dealing with chemicals, scaffold users should follow protocols for handling, storing, and disposing of hazardous substances. Heat and electricity should be approached with caution, and scaffold users should know how to safely use equipment and handle potential electrical hazards.
