Hazard Communication Training: Annual Refresher Course for the Division of Math and Sciences revised August 2007 Science Safety Committee: www.austincc.edu/sci_safe
The Texas Hazard Communication Actalso know has “HAZCOM” • is a law established to keep you informed about chemicals and other hazards in the workplace; • says that you, as an employee, have the "right to know" about chemicals that you may come in contact with while performing your job.
Definition of a hazardous chemical • a chemical is hazardous, or dangerous, if it can cause any of these: • injury to you • damage to your workplace • damage to the environment here are some examples of what hazardous chemicals can do to you
ACC’s Responsibilities as an employer: • to understand the HAZCOM standard • to develop and implement a HAZCOM plan http://www.austincc.edu/ehs/Hazcom.php • to identify and list all workplace hazardous chemicals • to maintain Material Safety Data Sheets (MSDSs) • to label all hazardous chemicals • to train employees in the safe handling and storage of hazardous chemicals
Your Responsibilities as an ACC employee: • 1. Ask your supervisor: • which chemicals stored or used in your workplace could cause damage or exposure • how to detect over exposure to a chemical (symptoms) • what to do in the event of a spill
Your Responsibilities as an ACC employee: • 2. Complete annual HAZCOM training. • 3. Know how to use MSDSs. • 4. Know how to read chemical labels. • 5. Know when and how to use personal protective equipment (PPE) to protect yourself from chemicals.
As an ACC employee, you have the right to: • 1. know the locations of hazardous chemicals • 2. know the location of and how to access: • the written ACC hazard communication program • a printed copy of the workplace chemical list • printed MSDSs • 3. receive training: • prior to your initial assignment • when changes occur in your assignment (for example, when you teach or prepare for a different course)
The ACC HAZCOM Program applies to: • 1. all ACC employees including • hourly employees • work-study students • 2. all ACC students
The ACC HAZCOM Program: • Details duties and responsibilities of employees and students • Requires reporting of chemical incidents • Requires each area to maintain an inventory of hazardous chemicals • Describes labeling requirements for containers of hazardous chemicals
Duties and Responsibilities of ACC Science Safety Coordinators: • 1. Keep records of safety incidents and corrective actions. • 2. Provide to the office of Environmental Health, Safety and Insurance Office by November 01 of each year: • a. a Work Area Chemical Inventory (WACI) for each work area; • b. annual notice of training completion for all employees. • 3. Approve the purchase of any chemicals not already on the WACI.
Duties and Responsibilities of ACC Science Safety Coordinators: • 4. Retain safety records for at least 5 years. • 5. Ensure that MSDSs are available for all chemicals purchased. • 6. Ensure that the requirements of the ACC HAZCOM Program and area implementation plan are fulfilled within their departments. • 7. Ensure that all employees have received appropriate training before working with or working in an area containing hazardous chemicals.
Duties & Responsibilities of ACC Employees and Students • 1. Report ALL incidents (for example spills and minor injuries) to the Science Safety Coordinator using the appropriate form (covered later in this program). • 2. Immediately report serious chemical incidents and incidents requiring outside medical assistance to the Environmental Health, Safety and Insurance Office by completing the appropriate form: • http://accweb.austincc.edu/accforms/forms/HZCM003injuryrep.pdf
HAZCOM Training is Required for: • all employees; • all students enrolled in laboratory courses and courses involving field activities.
HAZCOM Training is Required: • prior to beginning work in an area that contains hazardous chemicals; • annually; • whenever new hazards are introduced into the workplace; • when new or significant information is received on the hazards of chemicals; • when the potential for exposure increases.
HAZCOM Training must include: • how to find and interpret MSDSs; • how to interpret hazard labels (type and level of hazard); • location of hazardous chemicals the employee or student will handle; • how to safely handle and store hazardous chemicals; • how to find, select, use and care for appropriate PPE; • first aid treatment for chemicals the employee or student will use; • how to clean up spills.
Using Material Safety Data Sheets (MSDSs) • 1. Where do we get MSDSs? • Chemical manufacturers or distributors who supply hazardous chemicals to ACC must: • provide a MSDS with the initial shipment • provide a new MSDS with first shipment after an MSDS is updated
Company Info Hazardous Ingredients Physical Data Fire and Explosion Data Health Hazard Data Reactivity Data Spill and Leak Procedures Special Protection Information Special Precautions Using Material Safety Data Sheets (MSDSs)2. What is on a MSDS?
Section 1. Chemical product and company identification Section 2. Composition/ information on ingredients Section 3. Hazards identification, including emergency overview Section 4. First aid measures Section 5. Fire fighting measures Section 6. Accidental release measures Section 7. Handling and storage Section 8. Exposure controls/ personal protection Section 9. Physical and chemical properties Section 10. Stability and reactivity Section 11. Toxicological information Section 12. Ecological information Section 13. Disposal considerations Section 14. Transport information Section 15. Regulatory information Section 16. Other information MSDS Information Sections
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
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
Categories of Hazardous Chemicals • physical hazards - produce dangerous situations such as fires and explosions • health hazards - harm your body from the inside
Types of physical hazards: • combustible liquids • compressed gases • explosives • flammables • organic peroxides
Types of health hazards: • carcinogens • toxins • irritants • sensitizers • target organ effects Health hazards can have either acute (immediate) or chronic effects (occurring over a period of time).
Health hazards can enter your body through these routes: • absorption through skin or mucous membranes • ingestion by eating or drinking • inhaling / breathing in • puncture / injection
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
Threshold limit value (TLV) • is the airborne concentration limit of a substance under which nearly all workers may be repeatedly exposed without adverse effect.
Permissible Exposure Limit (PEL) • 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.
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 Chemical name Hazard warnings Manufacturer
HAZCOM Labeling and Marking Systems • NFPA Diamonds • HMIS Labels
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
Color Coding for NFPA Labels Red = Flammability Blue = Health/Toxicity Yellow = reactivity/stability White = special hazard information (NFPA)
Number Coding for NFPA Labels 4= Deadly Hazard 3= Severe Hazard 2= Moderate Hazard 1= Slight Hazard 0= No Hazard
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
Storing Chemicals Safely • all chemicals are stored according to hazard categories • incompatible chemicals are stored separately This is an example ofimproperly stored chemicals!
Personal Protective Equipment (PPE) The most important thing to remember about PPE is that it only protects you if you wear it!
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
PPE: Conditions Requiring Safety Eyewear • Eye protection must be worn when any of these is present: • chemicals • physical hazards • biohazards
PPE: Types of Safety Eyewear • There are two categories of safety eyewear: • Safety glasses – must have permanently attached side shields. • Goggles • Both types must meet the Z87 standard.
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
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
PPE: Using and Changing Gloves • check gloves for cracks, tears and holes before use • to remove gloves: • grasp outside of one glove and pull it off • hold that glove with your gloved hand • insert your fingers under the cuff of the other glove • turn that glove inside out over the first glove
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.
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.
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.
Chemical Spill Procedure • ACC’s written chemical spill procedures can be found at: • http://www.austincc.edu/ehs/pdf/Hazardous_Materials_Spill_Procedure.pdf
