Explanation:

This worksheet is about lab safety, which falls under the Natural Science discipline, specifically in the subfield of a general lab safety context (related to experimental sciences like Chemistry, Biology, or Physics lab work). Here are the typical answers for such lab safety worksheets (filling in the blanks with standard lab safety practices):

Prepare For Lab

• Always use safety equipment in the lab.
• Handle chemicals carefully.
• No food or drink in the lab!
• Read and follow all directions.
• Learn safety procedures.
• Find where emergency equipment is stored.
• Push lab stools in out of the way—keep aisles clear!

In Case of Incident

• Move swiftly, to a safe area (or "away from danger").
• Dispose of broken glass as directed, using proper tools (tongs, brush, dustpan).
• Clean up any spills, immediately with appropriate materials.
• Report any spills, to the teacher/instructor immediately!
• For a chemical spill on you skin, flush with water for 15 minutes (or as directed).
• For a chemical splash in your eyes, flush with eye wash station for 15 minutes (or as directed).
• In case of a large area of spill, notify instructor and follow emergency spill procedures (e.g., use spill kit).
• In case of fire: List 4 items that can be used depending on the case of the fire: Fire extinguisher, fire blanket, sand, water (for certain fires) (note: water isn't for all fires, but common options include extinguisher, blanket, sand, and knowing when to evacuate).

Dress For Lab

• No shorts, skirts, or open - toed shoes
• Roll up long sleeves
• Long hair MUST be tied back
• No loose jewelry (or "dangling jewelry") presently.
• Wear safety goggles, lab coat, or apron
• No books, bags, or purses in the lab area.

End of Lab

• Clean and put away all equipment and materials at the end of the lab period.
• Dispose of waste materials according to instruction.
• Always wash your hands after each lab!

The Lab Burner

• Never leave a lit burner unattended.
• Use caution when handling heated glassware
• Do not place hot glassware directly on the lab desk or in cold water
• Never heat a closed container
• Keep flammable materials away from open flames
• Point the end of a test tube being heated away from yourself and others!

Handling Chemicals

• Don't use chemicals that aren't labeled/approved for use
• Don't taste anything in the lab unless instructed to do so (for specific taste - safe experiments, rare)
• Smell by wafting (waving your hand over the container to direct smell to your nose)
• No unauthorized experimentation!
• Always add acid to water—never add water to acid
• Never return spilled or unused chemicals to the original bottle!
• Don't touch your face, eyes, or mouth while handling chemicals
• No food, drinks, or gum allowed in the lab.
