Question

question 15 (1 point) saved considerations for working under a chemical fumehood include: select all that apply. ensure chemical containers are stored at the back of the fumehood confirm the face velocity on the monitor is between 80 and 150 cfm work at least six inches inside the fumehood open the sash fully to have a clear view of the experiment declutter the fumehood to create a safe working space

Explanation:

• Storing chemicals at the back helps with proper airflow and containment. However, it's not an absolute must - just a good practice.
• Face velocity should be within the range for effective ventilation, but the range is typically 60 - 100 fpm for most fume hoods, not 80 - 150 cfm as stated (cfm is a unit of flow rate not velocity for this context, but assuming it's a mis - statement of velocity range it's still incorrect).
• Working at least six inches inside helps prevent fumes from escaping.
• Opening the sash fully disrupts the airflow and is unsafe.
• Decluttering ensures proper ventilation and a safe workspace.

Answer:

• Ensure chemical containers are stored at the back of the fumehood
• Work at least six inches inside the fumehood
• Declutter the fumehood to create a safe working space
