What’s the 1st safety rule?
• Clear the desk of anything unnecessary, and
• Read the board for directions
What’s the safety rule? Flood eyes with
water for 15 to 20 minutes if anything corrosive splashes in them (or if you think anything might have splashed in them).
What’s the safety rule? Never use a fire extinguisher on a
person; instead, use a fire blanket to smother flames on the person.
What’s the safety rule?
Always read the Material Safety Data Sheet (MSDS) prior to using any chemical. It will tell you how to use and dispose of the chemical safely.
What’s the safety rule? Always test
whether something is hot by holding the BACK of your hand over it, not by touching it.
What’s the safety rule? Read and follow
all directions carefully. It’s a good idea to “check off” each step of a procedure as you conduct it.
What’s the safety rule?
Always report injuries to the teacher before conducting a lab. Cover all cuts before working with chemicals.
What’s the safety rule?
Always clean up spills IMMEDIATELY, whether they are on the lab table or floor. Spills can cause dangerous accidents.

labels twice; they can look similar, but slight mis-readings can have dangerous results.
What’s the safety rule?
Never taste a chemical.
Never drink from a beaker or other piece of lab equipment.
What’s the safety rule? Always tilt test
tubes away from you and everybody else. Contents can spray or spurt on skin and eyes!
What’s the safety rule? Be very
careful when working with chemicals. Notice the person has two hands outstretched?
What’s wrong?
The scientist needs to use a funnel to pour from test tube into Erlenmeyer flask because test tube has no spout.
What’s the safety rule?
Always wear safety goggles when working with chemicals, electricity, or flame.
