What s the 1 st safety rule? Clear the desk of anything unnecessary, and Read the board for directions
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).
Know where all safety equipment is located AND how to use it. OR Put out chemical fires with an extinguisher, not water (which will spread the fire!),
Never use a fire extinguisher on a person; instead, use a fire blanket to smother flames on the person.
Never run or horseplay in the lab.
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.
Never smell a chemical directly. Always waft the odor toward your nose.
When diluting acid, always pour the acid into water, never water into acid.
Always wear safety goggles when working with chemicals.
Do not touch anything until you are given directions to do so.
Never stick anything into an electrical socket.
Do not touch broken glass. Report all damages to teacher immediately.
Pay for damages ASAP.
Always check electrical cords. Never use one that is broken or frayed.
Always test whether something is hot by holding the BACK of your hand over it, not by touching it.
Read and follow all directions carefully. It s a good idea to check off each step of a procedure as you conduct it.
Wash hands after every lab.
Never enter the storeroom.
