Science labs, whether at universies or in your home, are places of adventure and discovery. One of<br />
the first things sciensts learn is how excing experiments can be. However, they must also realize<br />
science can be dangerous without some instrucon on good laboratory pracces.<br />
• Read the protocol thoroughly before starng any new experiment.<br />
You should be familiar with the acon required<br />
every step of the way.<br />
• Keep all work spaces free from cluer and dirty dishes.<br />
• Read the labels on all chemicals, and note the chemical<br />
safety rang on each container. Read all MSDS (provided<br />

• Thoroughly rinse labware (test tubes, beakers, etc.) between<br />
experiments. To do so, wash with a soap and hot<br />
water soluon using a bole brush to scrub. Rinse completely<br />
at least four mes. Let air dry<br />
• Use a new pipet for each chemical dispensed.<br />
• Wipe up any chemical spills immediately. Check MSDSs<br />
