Science Safety

You have been injured in the laboratory (cut, burned, etc.). First you should

• visit the school nurse after class
• see a doctor after school
• tell the teacher at once
• apply first aid yourself

Long hair in the laboratory must be -

• cut short
• held away from the experiment with one hand
• always groomed neatly
• tied back or kept entirely out of the way with a hair band, etc.

When you finish working with chemicals, biological specimens, and other lab substances, always -

• treat your hands with skin lotion
• wash your hands thoroughly with soap and water
• wipe your hands on a towel
• wipe your hands on your clothes

After completing an experiment, all chemical wastes should be -

• left at your lab station for the next class
• disposed of according to your teacher's directions
• dumped in the sink
• taken home

When using a razor blade or scalpel, always cut material -

• away from you
• toward you
• in your hand
• perpendicular

• Used to smother fires on a person or an object
• Used to soak up chemical spills
• Used to keep warm in experiments involving a drop in temperature
• None of the above

Always point the open end of a test tube

• toward yourself
• toward your lab partner
• toward another classmate
• away from people

If a student spilled a chemical on their hand, where could you look to find the proper first aid instructions? 

• MSD- Mason Safety Document
• MSLS: Mason Schools Lab Safety
• MSDS- Material Safety Data Sheet

Never touch the eyewash or shower station unless it is a true emergency. 

• True
• False

It's fine to do random experiments with the lab equipment without teacher permission.

• Ummmm... no!
• Sure- it'd be fine!
