Hey! Listen!

• IF YOU ARE EVER GOING TO DO ANYTHING EVEN
  REMOTELY RELATED TO CHEMISTRY, PAY ATTENTION OR
  YOU COULD/WILL BE SERIOUSLY INJURED/DIE. THERE
  WILL BE A TEST AT THE END.

3
Basic Lab Rules

• Be aware of the risks
• Know where the safety equipment is
• Always wear goggles
• Tie long hair back
• No loose clothing
• No fooling around when in the lab/near lab
  equipment
• No food/drinks near lab equipment/during labs
• Ask teacher when unsure about anything
• Always report accidents right away
• Always clean up after yourselves when done labs

Know the Symbols
5
Some examples

• Compressed Gas Acetylene and oxygen are examples
  of compressed gases.
• Flammable and Combustibles Methane, acetone,
  lithium hydride
• Oxidizing Materials Ozone, chlorine, and
  nitrogen dioxide are oxidizing materials
• Immediate and serious toxic effects Styrene,,
  Hydrogen Cyanide
• Other toxic effects Abestos, Ammonia
• Biohazardous Any organisms and the toxins
  produced by this organism when the toxins have
  been shown to cause disease. Eg Human blood
  contaminated with Hepatitis B
• Corrosive Material Ammonia, fluorine, and
  hydrochloric acid are examples of corrosive
  substances.
• Dangerously Reactive Material Ozone, hydrazine,
  and benzoyl peroxide are examples of dangerously
  reactive materials.

How to Handle Them?

• Compressed gas
• Compressed gas should be moved and stored under
  extreme scrutiny because of the danger of
  breaching containers. Always have someone
  supervising you while moving or dealing with
  gases of the compressed nature because medical
  aid may be required when knocked out by shrapnel.
  The gases inside may also pose as a health risk
  to respiratory and other bodily systems. Wear
  proper protection such as goggles protective
  clothing.
• Combustible/flammable material
• Combustible and Flammable materials pose as a
  severe to chemical handlers because of the high
  risk of fire, Treat all of these with care and
  keep away from open flames or heat, store under
  cool, moist conditions and wear fireproof
  clothing. Always have someone nearby nearby with
  a flame retardant in case of fire.
• Oxidizing Material
• As with combustible and flammable substances keep
  away from heat and fire but most of all keep in
  airtight container. Make sure container is
  structurally sound and modern. Do not use old or
  outdated containers because of seal
  deterioration. Wear protective garb that is shock
  proof. Have someone with you to provide medical
  attention if harmed. Keep away from other
  chemicals.
• Immediate serious toxic effects
• Poisonous materials can cause maladies and have
  other ill effects leading up to even death. Be
  extremely careful not to get any on skin and
  especially careful not to ingest any. If you do
  call poison control and read supply information.
  Wear rubber or liquid proof clothing and if you
  are handling a gas wear a gas mask with a
  containment suit. Wash areas that come into
  contact with water if supplier info tells you to
  for recommended time. Do not always do this but
  if you don't know what it is there's a good
  chance it could save your life. Keep in suitable
  container.

How to Handle Them? (cont.)

• Materials causing other toxic effects
• Watch out for effects and symptoms BEFORE you
  handle chemicals on supplier data sheet. This way
  you will know what the chemicals are, how to
  protect against them and how to treat various
  areas of contact. Take all the same steps with
  poisonous materials as this. Keep in sealed
  container.
• Biohazrdous/infectious materials
• Treat all substances with extreme care and wear
  airproof garb to avoid gaseous transmission.
  Could have any number of side effects or
  symptoms. In most cases much worse than poisonous
  materials because Biohazardous materials are
  proven to transmit diseases and other infections.
  Keep under stern conditions in a sealed container
  in a sealed room under optimal conditions.
• Corrosive Materials
• Do not get on skin at any cost. Do not inhale,
  ingest, rub, intake, inject, or consume chemical
  on self. Keep away from metals, wood, and other
  materials that the supplier information will
  outline. Most of these can burn organic and
  metallic objects. Store in plastic container that
  is airtight. Do not breach container, wear rubber
  or other synthetic protective clothing.
• Dangerously Reactive Material
• Wear protective clothing that is durable. Take
  great care when transporting materials and do not
  jostle or make sudden moves of the chemical.
  Always keep under the very best conditions
  outlined in the supplier data and keep away from
  other substances. Extremely dangerous. Ingesting
  is a very bad idea. Keeping in a protective,
  shock proof container is a good idea.

What can go wrong

• Compressed gas
• - you could burn yourself, possible combustion
  when in contact with fire, too much oxygen in the
  air, and not enough oxygen in the air.
• Combustible/flammable material
• - open flames are a hazard near these substances.
  Electricity or sparks could ignite, and smoking
  can cause a flammable combustion.
• Oxidizing Material
• - having a combustible material with an oxidizing
  material is the biggest danger. They can
  decompose or explode if near heat.
• Immediate serious toxic effects
• - If swallowed, it could lead to poison and
  death, and if you get some on your skin, it could
  possibly poison you.

What can go wrong(cont.)

• Materials causing other toxic effects
• - not all substances make you sick immediately,
  that is why you keep it away from your skin and
  do not ingest.
• Biohazardous/infectious materials
• - this causes diseases and infections. Again,
  never allow on skin or ingest.
• Corrosive Materials
• - these will burn your skin and may burn things
  like your work bench. Always clean up
  immediately.
• Dangerously Reactive Material
• - if mixed with water, it causes a toxic gas. It
  will react if temperature or pressure changes. It
  can also react itself by breaking down. These
  material must be watched very carefully and
  contained well.

What is MSDS?

• - MSDS stands for Material Safety Data Sheet
• - A form with data regarding properties of a
  particular substance.
• - It is a list of health and safety information
  regarding exposure and cleanup for industrial
  chemicals in the workplace, which includes glues,
  cleansers and other products.
• - It is intended to provide workers and emergency
  personnel with procedures for handling or working
  with that substance in a safe manner, and
  includes information such as physical data.
