• A comes before W, so Acid is added to Water
• Pour slowly and do not splatter

Eye Safety

• Goggles must be worn at ALL times in the lab. If
  goggles are not worn, you will receive a zero on
  that lab.
• Eye Demo, Contact Demo, Goggles

10
Dress Safety

• No dangling jewelry. Necklaces, bracelets,
  watches, puffy sleeved shirts, and IDs that
  dangle may get caught on glassware, fall into
  chemicals, or swing into the flame.
• Long Hair Long hair should be tied back at all
  times when in the lab.

11

• No open toed shoes. This is to prevent broken
  glass, chemicals, and other harmful materials
  from getting on your feet.
• Pants are good for protecting your legs.
• Dont wear clothing that you would hate to have
  get dirty. The best prevention is to not wear
  nice clothes on days you know you will be in
  lab.

Safety Equipment

• Fire Extinguishers-
• A Combustibles (Paper, wood)
• B Liquids (Gasoline, Kerosene)
• C Electrical
• D Metal (Magnesium, Zinc)
• Most schools have ABC fire extinguishers. When
  working with metals we will have a D class fire
  extinguisher present in the room

13

• Chemical Spill In the case of acids or bases
  being spilt on the floor or lab bench, notify the
  teacher immediately, and get it cleaned up. This
  way it is not being tracked around in the room,
  and someone doesnt accidentally get it on them.
• Sand Used to extinguish metal fires.
• Baking Soda Used to neutralize an acid spill
• Kitty Litter Used to soak up and contain a
  liquid spill.

14
Student Use of the Laboratory

• No Unauthorized experiments.
• No eating or drinking in the lab. Chemicals can
  get into food and drink easily and without your
  immediate knowledge.
• Do not drink from lab equipment. You dont know
  what other people have put into the lab equipment
  that you are drinking from.

15

• Do not test the odor of a chemical directly. In
  order to prevent this, wafting is the procedure
  we use.
• Remember, hot glassware looks the same as cold
  glassware so always check it before grabbing hold
  of it.
• Always point test tubes away from yourself and
  others so that chemicals will not splatter out
  onto you, or others.

16

• NO HORSEPLAY!!! Horseplay in the lab is not
  allowed.
• Your group must clean their lab area completely,
  and leave everything organized.
• Leave the lab in an orderly manner with no
  pushing or shoving.

17
Before Lab

• Always READ the experiment beforehand. Sometimes
  a quiz will be given over the lab. Sometimes
  there will be questions to answer before being
  allowed to go to lab.
