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.

Container Label

HAZCOM Labeling and Marking Systems

NFPA Diamonds

HMIS Labels

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.

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
