Why do I need this training?
1) Someone said I had to be here…
2) I work with hazardous materials…
3) I potentially generate hazardous waste…
4) I live for the University and desperately want to protect its assets and investments…
If you answered yes to at least one of these statements,
then you’re in the right place!
Up to 1976, This is how hazardous
waste used to be disposed of
Of course, this is a terrible
solution for waste disposal.
So in 1976, the EPA developed waste management regulations
which we all follow to this day
Hazardous Waste Regulations• The University of Colorado must meet federal law requirements set in place
by the Resource Conservation and Recovery Act of 1976 (RCRA)
• This set up a “Cradle to Grave” process, where all hazardous materials must
be regulated from where it’s first used in the lab (cradle), all the way to
where it ends up after it leaves CU (Grave).
Treatment
Storage
Disposal
It turned this… Into this
What You Will Learn In This Training
1. General Laboratory Safety Requirements
2. Emergency Fire and Chemical Spill Procedures
3. Hazardous Waste Generation– If you produce a hazardous waste… then you are a Hazardous
Waste Generator
– If you are a generator, then you must have ANNUAL training (which we will remind you to take in a year)
1. Laboratory Safety
Requirements
• Personal Protective Equipment (PPE)
• Hazard Communication
(signs/labels/SDS)
• Chemical Storage/Labeling
• No Food/Drink In the Lab
• Gas Cylinders
• Lab Safety Equipment
• Emergency Procedures
Topics will Include
Personal Protective Equipment (PPE)
• PPE must be worn whenever in the lab
• Full length pants
• Closed toed shoes
• Protective Eyewear/goggles
• Gloves and lab coat
Crocs melt and allow
chemicals to reach
the skin, they do not
count as closed toed
shoes!
Hazard Communication
There are 3 main ways to
learn the hazards of a
certain chemical:
1. Product Labels
2. Safety Data Sheets
“SDS” (formally
MSDS’s)
3. NFPA sign and other
door signage
*Don’t be afraid to ask
colleagues or EH&S about
how to work with a dangerous
chemical! Product labels can give a Quick Look at hazards Inside!
Safety Data SheetsThese will have all of the Info on Hazards, Handling & Emergencies
• SDS
• Shows info for each topic:• Chemical Id (Name & synonyms)
• Toxicity (How the Chemical can harm you)
• Physical Characteristics
• Reactivity (Other chemicals that it may react with)
• Fire, Spill, First Aid (What is required in these situations)
• Available From:
• The chemical supplier
• EH&S
• Or you can even Google it, just make sure it is the exact same chemical!
NFPA Placards
• The National Fire Protection Agency (NFPA) labeling system is one of several labeling methods commonly used to advise hazards of chemicals.
• They can be found on container labels, the chemical’s SDS, and on your lab doors.
Chemical Storage and Labeling
• All Chemicals must be:
– Labeled!
– Kept in secondary containment to prevent spills
• Peroxide formers expire in 1 year! (Ethyl Ether, THF, etc.)
– Write date of opening on the label
– Write date of expiration if not already on the label
(1 year from open date)
• Store all chemicals with compatible
materials
There are 4 main separation groups
Acids --- Bases --- Flammables --- Oxidizers
Label, Label, Label!
We constantly find old and expired
chemicals in laboratories,
and tons of unlabeled/unknown
chemicals!
Please Label Everything
and store it properly!
Food and Drink Policy
• Campus policy is that absolutely no food or drink
is allowed in any laboratory space
• All eating and drinking must be done outside the lab
(Sorry, no exception for if your desk is in the lab area)
Gas Cylinders
• Keep all the tags and labels on the bottle
• All cylinders must stay secured to a stationary object
like a wall, lab bench, or cylinder rack
Lab Safety Equipment
• Know the Location of:
• Eyewashes/Showers
• Fume Hoods
• First Aid Kits
• Fire Extinguishers
• Fire/Chemical Alarms
• SDS’s
• Spill Cleanup Equipment
• Exits
2. Spills & Fires
-A Small “Incidental” Spill vs. an Emergency Spill Response
-Campus Fire Policy
Incidental Spill
Have a small spill occur? Think of the SQUID!
• Spill is small in nature
• Quickly locate spill cleanup materials
• Isolate and clean up the spill using proper protection (PPE)
• Dispose of the waste from cleaning up properly
Watch the
Quick Example
Video!
Emergency Spill Scenario
A one gallon container of Toluene, a flammable poison, fell and shattered onto the floor of your lab. Some of the toluene has splashed
onto one of your co-workers’ legs, arms, and clothes.
What do you do now?!
Watch the
Quick Example
Video!
Emergency Spill Response
Don’t be a social LEPER, Remember these steps!
• Life Safety First• Remove all affected clothing and rinse exposed skin/eyes for at least
15 minutes in a nearby emergency shower/eyewash
• Evacuate the immediate area
• Pull the nearest fire or chemical alarm in the hallway
• Execute a 911 call from a safe location
• Remain available for emergency personnel
• Is there such a thing as a small (unintentional) fire?– No! Campus policy is that every fire should be treated like a big fire
• FIRST: Follow Emergency Spill Response Procedure– The LEPER Steps
• THEN: Attempt to extinguish the fire if you’re
comfortable doing so
– Fire Dept. is already on its way in case you aren’t successful,
saving valuable time
Fires
3. Hazardous Waste!
Now that you know how to safely work in a laboratory and with hazardous chemicals,
What do you do with the hazardous waste you have generated?!
What is Hazardous Waste?!
• By Regulation, anything that shows a certain characteristic:• Corrosive• Toxic• Ignitable• EPA Listed
• Buffers, salts, agar, and water are just about the only things not considered hazardous waste
• If in doubt ask the EH&S and our Haz-Waste Management group
• No Hazardous Chemicals can go down the
drains or in the trash!
• Absolutely no liquid can go in the trash
Waste Disposal
So Where Does it Go?
• State and Federal regulations require all hazardous waste to be stored in a Satellite Accumulation Area (SAA) after it is generated.
• EH&S is required to know exactly where all haz-waste is on campus, so we have set up SAAs for all of your labs and facilities.
• SAAs are required to be inspected weekly!
– We have a NEW online solution for this!
Regulations for
All Hazardous Waste Containers
1. All containers are labeled with all of it’s contents and as “Hazardous Waste”
*Using a EH&S disposal tag is best =
2. Containers are closed and not leaking or bulging
3. Group all waste containers according to chemical compatibility
4. Everything is in secondary containment
5. Less than 55 Gal. total of waste
6. Not a P-Listed Acutely Toxic waste
(Dispose these immediately through EH&S)
What‘s Wrong Here?
No labeling of its chemical contents
No “HazardousWaste” label
Open Container
No Secondary Containment
Not In a designated SAA
How to Check the SAA Every Week
• Complete the SAA inspection by
visiting the EHS Website
– Https://ehs.Colorado.edu
– Click the link found on the home page to
check login and check the SAAs
• Every SAA in the lab must be inspected at least once a week
A “week” is from Sunday to Saturday
• We send a friendly reminder to everyone in the lab on Friday if the SAA hasn’t gotten checked yet that week
The Online log needs to be checked by Saturday Midnight
• If nobody in the lab inspects the SAAs for that week, the lab will received a Notice of Non-Compliance
Too many of these won’t be good for the lab!
Hazardous Waste Tag
• Haz-Waste is disposed of through EH&S by submitting a haz-waste disposal tag
• Completely fill out one of these tags and attach it to the waste container
• Use Full Chemical Names in English
– Include any trace amount of materials and every solvent (even water!)
• Write the best guess of percent for each material. Total should reach = 100%
• Campus mail the top white sheet to EH&S (UCB-413)
Haz-Waste Disposal Crew’s Wish List:
1. Please write legibly
2. Keep all Mercury separate from other waste
3. If you have multiple containers of the exact
same waste = you can write it all on one tag
and attach it to all the containers.
4. Write the physical state of the chemical, the
amount in the container, and its pH!
5. Been waiting 2 weeks and the waste is still
there? Call us at 303-492-7845
NOT LIKE THIS!!
Empty Containers & Broken GlassEmpty Bottles
1. Remove the Cap
2. Destroy/Cross out the label
3. Label the bottle as “Empty”
4. Container can then be disposed of directly in a dumpster.
-NOT in a normal trash can!
*P-Listed chemical bottles must go through EH&S
Non-Contaminated Broken Glass
1. Accumulate in a puncture-resistant box
2. Have separate accumulation boxes for chemically contaminated and clean broken glass
*Lab glass is not allowed in campus recycling*
If the waste is contaminated with Heavy
metals, Acute toxins, or hazardous
chemicals, it must be accumulated for
EH&S disposal.
1. Accumulate in a puncture resistant
container
(cardboard box, plastic container, etc)
2. Fill out and attach a haz-waste disposal
tag, listing out all chemicals the waste
is contaminated with
3. Submit to EH&S for disposal.
Broken Glass and Pippete Tips
Chemically Contaminated Non-Contaminated
If there is no chemical contamination, the
waste can be accumulated for eventual
disposal in a dumpster
1. Accumulate in a puncture resistant
container
(cardboard box, plastic container, etc)
2. Label it as “Non-Hazardous”
3. Close the container or seal it with tape
4. Bring directly to a dumpster for
disposal
Metal Sharps and
Biomedical Appearing Things
• Regardless of contamination or not, All Metal
sharps must be disposed of through EH&S as
hazardous waste!
– Razor blades, scalpels, needles etc.
• As well, Bio-Medically appearing things must
be disposed of as hazardous waste
– Syringe barrels, tips, needles etc.
Do NOT use broken glass boxes like
trash cans!
Otherwise you will have to sort through the whole box No Needles!
No Liquids!
No Trash!
Biological Waste
If you will be working with biohazardous material, you will require separate
trainings, and need to contact our Biosafety group at [email protected]
• Unless you are trained, Do not touch anything labeled as biohazardous
• All biologically contaminated materials must be rendered non-infectious
• Bleach
• Autoclave
• Autoclaved material should be placed in bins for pickup, and have the top white
copy of the Non-Biohazardous Certification Tag put in the sleeve…
Radioactive Material
If you will be working with radioactive material, you will require separate trainings, and need to contact our Health Physics group at 303-492-6523
What is radiation?
• All materials, including radioactive materials, are made up of atoms
• Radioactive atoms are unstable and have extra energy which is released as “radiation”.
• This energy can be hazardous to humans if not used safely.
• Radioactive contamination is loose radioactive material (like invisible dust) which can get on your clothing and shoes.
• Exposure to radiation happens when you are around radioactive materials, even when you are not in direct contact with it.
Recognizing radiation use areas
• The universal Radiation Symbol (trefoil ) is used to notify you of the presence of radiation. Equipment and areas marked with this symbol should be treated carefully.
• Unless you are trained, do not touch anything labeled as radioactive.
• Radioactive materials which can cause contamination are called “unsealed sources”
• Radioactive materials which are bound in metal or plastic are called “sealed sources.”
• Other labs may use X-ray machines or LASERs. These machines are not dangerous if they are not turned on.
• At very high amounts, much greater than those found at CU, radiation can cause burns and damage to cells.
• The principle hazard from exposure to radiation is an increase in the risk of developing cancer.
• No one knows how much radiation it takes to cause cancer, but the amount of radiation used at CU is very small.
• There are rules and regulations in place at the University of Colorado which are designed to reduce your risks from exposure to radiation
Radioactive Material
Working Safely Around Radiation
• It is recommended to wash your hands immediately after working in a lab with radioactive materials, in order
to effectively remove any radioactive contamination you may have received.
• Radioactive waste cans look different than regular trash cans. They are marked with the trefoil and are usually
a different color. These should not be emptied or moved.
• If you notice a leaking waste container or other issue, contact the CU Radiation Safety Office at 492-6523 or
call 911.
Security of Radioactive Materials
• It is very important that radiation labs be locked when no one is present in the lab. Always be sure to lock the
door behind you if you are the last to leave.
• Restrict access to strangers, and question any trespasser to the lab.
• If you ever think you may have been contaminated with radiation, you don’t need to panic!
However, do not leave the lab, as you may spread the contamination.
• Ask for a member of the lab to help you by calling the EH&S Health Physics Group at 303-492-
6523 to get properly decontaminated.
• Always Call 911 if immediate life and health is at risk.
