Work Area Chemical Inventory (WACI)
Each work area will maintain an inventory list (WACI) of all chemicals present in the work area regardless of quantity
WACIs will be updated by the designated person annually and when new chemicals are
added WACIs will be provided to the Science Safety
Coordinator annually and when updated
August 2007 24
The WACI contains this information: name and phone number of the person responsible
for the work area and the name and signature of the person responsible for compiling the inventory
area name location of the hazardous chemicals (building and
room) chemical name or the common name of the product
and its ingredients CAS numbers container types hazards associated with the chemical maximum quantity that would be on hand at any time
August 2007 25
Categories of Hazardous Chemicals
physical hazards - produce dangerous situations such as fires and
explosions
health hazards - harm your body from the inside
August 2007 26
Types of physical hazards:
combustible liquidscompressed gasesexplosivesflammablesorganic peroxides
August 2007 27
Types of health hazards:
carcinogenstoxinsirritantssensitizerstarget organ effects
Health hazards can have either acute (immediate) or chronic effects (occurring over a period of time).
August 2007 28
Health hazards can enter your body through these routes:
absorption through skin or mucous membranes
ingestion by eating or drinkinginhaling / breathing inpuncture / injection
August 2007 29
Evaluating and Controlling the Risk of Chemical Exposures
The chemicals we use have been tested (on animals) to establish estimates of how much of the chemical we can be exposed to OR how long we can be exposed to it before it has deleterious effects on us.
There are many terms used to describe these limits: TLV, PEL, TWA, STEL, and ceiling limits
August 2007 30
is the airborne concentration limit of a substance under which nearly all workers may be repeatedly exposed without adverse effect.
Threshold limit value (TLV)
August 2007 31
is the maximum amount or concentration of a chemical that a worker can be exposed to.
PELs are measured in different ways:1. Ceiling limits are amounts or concentrations of a
chemical that should never be exceeded even for very brief periods of time.
2. A time weighted average (TWA) is the upper limit of exposure for a normal 8-hour work day.
3. A short term exposure limit (STEL) is the concentration of a chemical that a worker can be exposed to for a short period of time without suffering irritation, chronic or irreversible tissue damage.
Permissible Exposure Limit (PEL)
August 2007 32
Guidelines for Labeling Hazardous Chemicals
1. Primary container labels should contain:• identity of chemicals• physical and health hazards, including target organs• manufacturer’s name and address
2. Secondary container labels must contain all of the above except the manufacturer’s information.
3. Replace labels if they don’t meet standards or are illegible.
4. NEVER have any unlabeled, unattended containers in your work area.
August 2007 35
NFPA Diamonds
•color coded, numerical rating system•located near main entrances, fire alarm panels, on outside entrance doors or cabinets•provide at-a-glance hazard
information
August 2007 36
Color Coding for NFPA Labels
Red = Flammability
Blue = Health/Toxicity
Yellow = reactivity/stability
White = special hazard information (NFPA)
August 2007 37
Number Coding for NFPA Labels
4= Deadly Hazard
3= Severe Hazard
2= Moderate Hazard
1= Slight Hazard
0= No Hazard
August 2007 38
HMIS Labels
•designed to go on individual containers of products that don’t have manufacturer’s labels•same color code/numerical rating system as the NFPA diamonds with one exception•white = personal protective equipment or special protection information
August 2007 39
Storing Chemicals Safely
all chemicals are stored according to hazard categories
incompatible chemicals are stored separately
This is an example of improperly stored chemicals!
August 2007 40
Personal Protective Equipment (PPE)
The most important thing to remember about PPE is that it only protects you if you wear it!
August 2007 41
Instructors must:
Wear the required PPE for the lab activity Ensure that students wear the required PPE Ensure that the PPE is worn by all students
during the entire lab activity
August 2007 42
PPE: Conditions Requiring Safety Eyewear
Eye protection must be worn when any of these is present:
chemicals physical hazards biohazards
August 2007 43
PPE: Types of Safety Eyewear
There are two categories of safety eyewear:
1) Safety glasses – must have permanently attached side shields.
2) Goggles
Both types must meet the Z87 standard.
August 2007 44
PPE: Choosing Safety Eyewear
• Goggles provide the best all around protection.
• If it is necessary to wear contact lenses in the lab, wear protective goggles rather than safety glasses.
• Regular eyeglasses do not provide adequate protection when working with chemical or physical hazards
August 2007 45
PPE: Choosing Gloves
• any glove can be permeated by chemicals
• nitrile gloves are more resistant to most chemicals than latex gloves
• special gloves must be worn when handling materials that are hot, very cold, or sharp
August 2007 46
PPE: Using and Changing Gloves
check gloves for cracks, tears and holes before use
to remove gloves:1) grasp outside of one glove and pull it off
2) hold that glove with your gloved hand
3) insert your fingers under the cuff of the other glove
4) turn that glove inside out over the first glove
August 2007 47
PPE: Other Protective Clothing
Lab coat: primary purpose is to protect against splashes and spills; they should be non-flammable and
easily removed. Rubber-coated apron: can be worn to protect against
chemical splashes and be worn over a lab coat for additional protection.
Shoes: must fully cover the feet and should always be worn when chemicals are in use.
Hard hat: must be worn when there is a hazard from falling rock debris.
August 2007 48
First Aid
• Only minor injuries will be treated in the lab.• Do not give or recommend oral medications to
students.• Note use of supplies on form in first aid kit.
August 2007 49
Universal Precautions
are designed to prevent transmission of human immunodeficiency virus (HIV), hepatitis B virus (HBV), and other blood borne pathogens
Assume that all body fluids are infectious. Do not come into contact with anyone’s body fluids. For cleanup of body fluids (blood, vomit), contact the
campus administration office for assistance.
August 2007 50

these conditions exists:
• the spill volume is less than one liter (~quart)• it contains chemicals that have a hazard rating
below 2 in all hazard categories• you have been trained in spill clean up
procedures• you have adequate PPE
August 2007 55
What you need to do for a Section 2 Spill:
restrict access to area of spill immediately notify your supervisor and others in area of
the spill mark the area to prevent others from coming in contact
with the spill obtain the MSDSs and refer to the spill clean up
instructions report the spill to EHS (M-F 8am to 5 pm) or Campus
Police (any other time)1. identity and quantity of chemical spilled
2. exact location of spill
Campus Police will contact EHS.
August 2007 56
Reporting Incidents
All lab incidents need to be reported so that if a problem in equipment or procedures exists, it can be fixed to prevent further problems.
Incidents are categorized as• non-injury• injury (to an employee or student)
minor - treated by using materials from the first aid kit) major – eye injuries, head injuries or anything
requiring treatment by EMS or a physician
Follow these procedures to report incidents
