1 HAZARD COMMUNICATION AND GHS
WITH THE GLOBALLY HARMONIZED SYSTEM (GHS) OF CLASSIFICATION AND LABELING OF CHEMICALS FOR WASHINGTON STATE EMPLOYERS Funding and support for this project has been provided by State of Washington, Department of Labor and Industries, Safety and Health Investment projects.

2 HAZARD COMMUNICATION PROGRAM
What is a HAZCOM plan? What does GHS mean? How do hazardous chemicals affect the body? What are the different types of hazardous chemicals? What is on GHS compliant product labels? What are Safety Data Sheets (SDS)? How to protect yourself from hazardous chemicals. Note: For HAZCOM compliant training, if type is in orange on slides, make sure the employees you are training do the activity and you update your HAZCOM program to match the responses of your COMPANY.

3 HAZARD COMMUNICATION What is hazard communication? Employees who work with Hazardous Chemical have a “Right to Know” : what those chemicals are, what hazards are associated with those chemicals, what they can do to protect themselves, how to handle and store products they work with, what to do if they have an emergency working with those chemicals. Employers need a formal written program that includes employee training. This is often called a “HAZCOM” program. They need to be based on WAC “ The WISHA hazard communication (“hazcom”) regulations are found in the Core Rules – WAC We have copies if you wish to see them.” 2

4 GHS What is GHS? Globally Harmonized System of Classification and Labeling of Chemicals - needed because of global economy Internationally Developed System to protect workers by using the same criteria (testing procedures, exposure limits, etc) to determine the hazards of chemicals Safety Data Sheets must be created based on the same 16 part format The use of visually based warning symbols (pictograms) on product labels so workers can immediately identify the hazards associated with the products they use. “ The WISHA hazard communication (“hazcom”) regulations are found in the Core Rules – WAC We have copies if you wish to see them.” 2

5 WHO NEEDS A HAZCOM PROGRAM?
What kind of companies need a HAZCOM plan? Cleaning Services Labs Any company that manufactures, distributes, transports (additional rules), stores, or disposes of chemicals. Flooring Installers Retail Stores Trucking Companies Any company whose employees work with hazardous chemicals. Wholesale Warehouses Examples: Healthcare Facilities Contractors Fire Departments Painting Contractors Machine Shops Pool Supply Auto Repair and Oil Change Shops Maintenance Companies Welding Shops “ The WISHA hazard communication (“hazcom”) regulations are found in the Core Rules – WAC We have copies if you wish to see them.” 2

6 What must our company do to be in compliance?
HAZCOM COMPLIANCE What must our company do to be in compliance? Companies must have a written HAZCOM Plan. It includes list of chemicals you have in your workplace. Collect an SDS (MSDS if SDS is not available) for each of the chemicals and have available for employees. Train your employees on how to read an SDS and Hazard Label. Provide proper PPE for the chemicals your employees use.

7 What is considered a “Hazardous Chemical?”
HAZARD COMMUNICATION What is considered a “Hazardous Chemical?” A hazardous chemical is any chemical that can do harm to your body Most industrial chemicals can harm you at some level Employees who use chemicals (other than retail packaged products used for their intended purpose) must have access to the SDS and warning labels for products they use at work. “Some chemicals are more toxic than others. Just a little bit of some chemicals entering your body could harm you. Others are much less toxic and it would take great amounts entering your body to do any harm.”

8 How do hazardous chemicals affect the body?
HAZARD COMMUNICATION How do hazardous chemicals affect the body? The effect a certain chemical has on the body depends on several factors: The physical form of the chemical How the chemical enters the body The amount of chemical that actually enters the body - the dose How toxic (poisonous) the chemical is “ A poisonous chemical will not do you any harm, obviously, if it does not enter your body.”

9 The Three Forms of Chemicals
TYPES OF CHEMICALS The Three Forms of Chemicals All chemicals exists in one of three forms: Solid Liquid Gas “The physical form of the hazardous chemical can affect how hazardous it is and how it enters the body.”

10 Solids – Dusts and Particulates
CHEMICAL SOLIDS Solids – Dusts and Particulates Dust or powder can be released into the air by cutting, drilling, grinding or sanding and inhaled Dust can also be stirred up by dry sweeping and inhaled Spraying Paint causes particulates to be suspended in the air “ For example, cutting brick or cinder block without water can generate lots of dust that contains quartz (silica). If silica dust is inhaled it can scar the lungs and cause breathing problems.”

11 Solids – Fumes and Fibers
CHEMICAL SOLIDS Solids – Fumes and Fibers Fumes are extremely small droplets of metal formed when the metal has been vaporized by high temperatures (usually welding) Some compounds are fibers which can be similar to dusts but they have an elongated shape (like asbestos or fiberglass) “ Metal fumes are formed during welding. Because of their tiny size, they are easily inhaled deep into the lungs and can be absorbed into the blood stream.” “Asbestos and quartz (or silica) are one of the most hazardous dusts because of the damage they do to the lungs. Fiberglass does not damage the lungs, but can be irritating to the respiratory system.”

12 CHEMICAL LIQUIDS Liquids Liquids can come into direct contact with the skin and be absorbed into the body Liquids can be sprayed and form mists or evaporate and form vapors which can be inhaled “Typical hazardous liquids are various types of solvents. Some liquid solvents are flammable and can be a fire hazard as well.”

13 CHEMICAL LIQUIDS Liquids (Mists) Mists can also be inhaled Mists can settle on the skin and be absorbed Airborne mists can also settle out and contaminate food or drink “The most common exposure to mists is from inhalation. A common example of a mist exposure at work is paint overspray.”

14 CHEMICAL GASES Gases Some can occur naturally Vapors can form from liquids Carbon Monoxide, Hydrogen Sulfide, and Ammonia gas are some chemicals that have killed workers in the gas form “The most common exposure to mists is from inhalation. A common example of a mist exposure at work is paint overspray.”

15 There Are Five Routes of Entry:
HOW CHEMICALS ENTER THE BODY There Are Five Routes of Entry: Ingestion – swallowing the chemical Inhalation – breathing in the chemical Absorption – the chemical soaks through the skin Skin or eye contact - chemical does external damage to skin or eyes on contact Injection - sharp object pierces the skin “Inhalation is typically the most common way chemicals can enter the body in a work situation. Skin absorption is less common, but can occur with some solvents and pesticides. Ingestion is usually not a major problem in the workplace except in certain situations.”

16 Ingestion (Swallowing)
HOW CHEMICALS ENTER THE BODY Ingestion (Swallowing) Chemicals that are swallowed are absorbed in the digestive tract Chemicals can rub off dirty hands and contaminate food, drinks or tobacco products Chemicals in the air can settle on food or drink and be swallowed “This is another good reason to wash your hands before eating, drinking or smoking.”

17 Inhalation (Breathing)
HOW CHEMICALS ENTER THE BODY Inhalation (Breathing) Airborne chemicals are breathed in through the mouth or nose The size of particles or droplets can affect where the chemical settles in the respiratory tract Where the chemical settles in the respiratory tract determines what symptoms or diseases will develop “Some chemicals settle in the nose and throat, some go deeper into the lungs. The chemicals that go deeper in the lungs often cause more damage. Fine dust usually goes deep into the lungs”

18 [note: during slide show photo appears after 4 second delay.]
HOW CHEMICALS ENTER THE BODY Skin Absorption Some chemicals can pass through the skin and be taken into the body’s systems Solvents and pesticides are examples of compounds that can be absorbed through the skin “Some chemicals are absorbed through the skin more easily than others. Many insecticides and some solvents are easily absorbed through the skin.” [note: during slide show photo appears after 4 second delay.] 15

19 CORROSIVE CHEMICALS Skin Contact Corrosives can cause visible skin burns or damage The extent of skin damage depends on how long the corrosive is on the skin and how concentrated the corrosive is Acute chemical burn day later days later “The longer the corrosive is on your skin, the greater the injury. The more concentrated the corrosive, the greater the damage.” 24

20 CORROSIVE CHEMICALS Eye Contact Inhalation of corrosive mists or vapors can cause severe bronchial irritation Corrosive chemicals are capable of damaging skin, eyes and the respiratory system “Corrosive chemicals may or may not have an internal effect on the body, but usually affect the skin or eyes, irritating or destroying tissue. This can also happen in the lungs if corrosive chemical vapors are inhaled.” Acute chemical burn to the eye 23

21 [note: during slide show photo appears after 4 second delay.]
HOW CHEMICALS ENTER THE BODY Injection Some chemicals can pass through the skin and be taken into the body’s systems thorough a break in the skin Needles and sharp objects cause injection hazards “Some chemicals are absorbed through the skin more easily than others. Many insecticides and some solvents are easily absorbed through the skin.” [note: during slide show photo appears after 4 second delay.] 15

22 Toxicity: How dangerous are chemicals?
CHEMICAL TOXICITY Toxicity: How dangerous are chemicals? Dose - The effects of any toxic chemical depends on the amount of a chemical that actually enters the body Acute Toxicity - The measure of how toxic a chemical is in a single dose over a short period of time Chronic Toxicity – The measure of the toxicity of exposure to a chemical over a long period of time Lethal Dose - expressed as LD50 or dose at which 50% of a population will die. [Optional slide. These terms are often used in MSDSs.] “ Some chemicals can cause problems immediately, others may not hurt you until you have been exposed for a long time” 16

23 Chronic Toxicity and Acute Toxicity
CHEMICAL TOXICITY Chronic Toxicity and Acute Toxicity Some chemicals will only make you sick if you get an ‘acute” or high dose all at once Example - ammonia Some chemicals are mainly known for their chronic or long-term effects Example - asbestos Most chemicals have both acute and chronic effects Example – carbon monoxide “Ammonia smells terrible and irritates the nose, but doesn’t really hurt you except at very high levels where it can burn your lungs. At lower levels, it has no long-term effects. Asbestos has no immediate effects , but over the long-run causes breathing problems or lung cancer. Carbon monoxide can kill you in minutes at a high enough level, but also give you headaches and eventually damage your heart if you breathe it day after day at low levels.” A lethal dose (LD) is an indication of the lethality of a given substance or type of radiation. Because resistance varies from one individual to another, the 'lethal dose' represents a dose (usually recorded as dose per kilogram of subject body weight) at which a given percentage of subjects will die. The LD may be based on the standard person concept, a theoretical individual that has perfectly "normal" characteristics, and thus not apply to all sub-populations. Lethal doses are usually expressed as median lethal dose (LD50), the point where 50% of test subjects exposed would die, in the units of mg/kg body weight. For gases and aerosols, lethal concentration (mg/m³ or ppm, parts per million) is the analogous concept, although this also depends on the duration of exposure, which has to be included in the definition. The lowest known lethal dose, derived from an individual case of poisoning, is abbreviated LCLo. 17

24 What are some of the things chemicals can do to you?
HEALTH HAZARDS What are some of the things chemicals can do to you? Carcinogens - these chemicals may give you CANCER. Check to see if the chemicals you are using are on DOSH’s carcinogen list for special rules when working with these chemicals. Teratogens - these chemicals hurt unborn babies, or CAUSE BIRTH DEFECTS. Mutagens- these chemicals cause BIRTH DEFECTS and sometimes CANCER in the exposed worker Sensitizers - these chemicals can cause an ALLERGIC REACTION in smaller and smaller doses, that can be deadly. 18

25 Chemical Exposure Limits
CHEMICAL TOXICITY Chemical Exposure Limits Many chemicals have exposure limits, or allowable amounts of a chemical in the air without having to wear additional protection. These limits are often called “PELs” or “TLVs”. They are based on 8-hour average exposure or ceiling or peak levels. Levels must be kept below these limits for safety. Employers have an obligation to monitor for many of these chemicals or use historical data to estimate PEL Example: 100 parts per million “PEL” means “permissible exposure limit”. “TLV” – means “threshold limit value”. WISHA regulations have PELs for about 600 chemicals. Often the MSDS will list the OSHA PEL which can be different from the WISHA PEL. The limits are usually expressed as parts per million (ppm) or milligrams per cubic meter (mg/cu. meter). Your exposure to chemicals cannot exceed these limits.” The TLV for chemical substances is defined as a concentration in air, typically for inhalation or skin exposure. Its units are in parts per million (ppm) for gases and in milligrams per cubic meter (mg/m³) for particulates such as dust, smoke and mist. The basic formula for converting between ppm and mg/m³ for gases is ppm = (mg/m^3) * / molecular weight. This formula is not applicable to airborne particles. Three types of TLVs for chemical substances are defined: Threshold limit value - Time weighted average (TLV-TWA): average exposure on the basis of a 8h/day, 40h/week work schedule Threshold limit value - Short-term exposure limit (TLV-STEL): spot exposure for a duration of 15 minutes, that cannot be repeated more than 4 times per day with at least 60 minutes between exposure periods Threshold limit value - Ceiling limit (TLV-C): absolute exposure limit that should not be exceeded at any time There are TLVs for physical agents as well as chemical substances. TLVs for physical agents include those for noise exposure, vibration, ionizing and non-ionizing radiation exposure and heat and cold stress. 18

26 Too Lean Too Rich Methane 100% 5.3% LFL 15.0% UFL
PHYSICAL HAZARDS - FLAMMABILITY Flammable Range: The limits of flammability is the range that a mixture of air and vapor is flammable. Chemicals have an upper and lower flammability limit (LFL, UFL). Vapor pressure is a measure of how fast a liquid evaporates. Air 100% Air 0% Too Lean Too Rich Methane 0% Boom! Methane 100% 5.3% LFL 15.0% UFL The flash point is the lowest temperature that a flammable liquid can generate enough vapor to form a mixture with air that will ignite.

27 PHYSICAL HAZARDS - VAPOR DENSITY
“Vapor density” is a measure of how heavy a vapor is compared to air. Air has a vapor density of 1. Vapors with a density greater than air can flow like a liquid collect near the floor. Acetone, for example, has a vapor density of 2 and sinks. This may create a fire or explosion hazard if the vapor flows to an ignition source. “An example of vapors heavier than air include propane. A leak from a propane tank will often settle in the lowest part of building or ground.” 34

28 Explosions are physical hazards.
PHYSICAL HAZARDS - EXPLOSIONS Explosions are physical hazards. Explosive; fire, blast or projection hazards by self-reactive substances, substances that can burn without oxygen; or that may explode when disturbed will be labeled with this symbol. Explosions are often caused by pressurized cylinders and can be accelerated by oxidizers. “An example of vapors heavier than air include propane. A leak from a propane tank will often settle in the lowest part of building or ground.” 34

29 THIS IS ALL GETTING A BIT TECHNICAL - HOW DOES IT WORK WITH THE AVERAGE EMPLOYEE?

30 Works for Industrial Maintenance Company for Historic Buildings
CHEMICALS AT WORK MEET BOB Works for Industrial Maintenance Company for Historic Buildings Does everything from cleaning windows, to restoring metal surfaces, to repair grout Bob works with many different kinds of chemicals

31 How can Bob’s Company protect him from Chemicals?
CHEMICALS AT WORK How can Bob’s Company protect him from Chemicals? The HAZCOM ADMINISTRATOR for his company trains Bob on Chemicals, SDS, and Labels with this Presentation BEFORE Bob works with hazardous chemicals. Give Bob access to a list of SDS and copies of SDSs for the chemicals he works with, so he that he can double check all procedures. Make sure Bob has the correct PPE for the chemicals he works with. Our company’s HAZCOM Administrator will be:___________________ * Put in HAZCOM PLAN

32 What does Bob need to know about chemical labels?
HAZCOM TRAINING- GHS LABELS What does Bob need to know about chemical labels? Bob learns the products he works with need to come with a warning label. He needs to leave the product in the original container whenever possible. If he puts the chemical in a new container, he needs to put a GHS Label on the container. That will be our companies plan too.

33 2. Signal Words help define how dangerous a chemical is:
GHS LABELS MUST HAVE 6 THINGS 1. Product Identifier 5. Precautionary Statements- recommended measures of prevention, response, storage and disposal. 2. Signal Words help define how dangerous a chemical is: Danger - More Dangerous Warning - Less Dangerous 3. Hazard Statements Statements that describe the nature of the hazard(s) of a chemical including, where appropriate, the degree of hazard. 6. Name, address, and telephone number of the chemical manufacturer, importer, or other responsible party. 4. Pictograms

34 Did you say “MAKE” a label?
MAKING LABELS Making GHS Labels: The information you need to make a label for a product is on the SDS (MSDS) for the product. Many online label making services (JJKeller) and apps are becoming available where you can make or get a GHS label on the jobsite using an IPad or Smartphone. Did you say “MAKE” a label? How do we do that? Our company will make labels by: _____________________________ * Put in HAZCOM PLAN

35 What do the Pictograms mean? Health Hazards
GHS HAZARD COMMUNICATION What do the Pictograms mean? Health Hazards Physical Hazards Environmental Hazards

36 GHS PICTOGRAMS Most of the cleaning products Bob uses have some minor health effects and may cause skin to become irritated. Exclamation Point: Chemicals that are acutely toxic and that can be harmful or toxic by ingestion, inhalation, or contact with the skin or eyes, often with a small dose.

37 GHS PICTOGRAMS Cleaning Supplies: Some of Bob’s cleaning supplies can cause longterm health effects like cancer, other can make him violently ill and do damage to specific organs.

38 GHS PICTOGRAMS Health Hazard: Chemicals that pose Health Hazards and can cause acute or chronic health effects such as respiratory function damage, cancer, specific organ function damage, sexual dysfunction, fertility problems, birth defects and genetic mutations are represented by this symbol.

39 PICTOGRAMS Bug Spray: One of Bob’s jobs is to spray for bugs. If he accidentally ingested some of the chemical or some absorbed through his skin, it would be bad! In fact....

40 PICTOGRAMS Skull and Crossbones: Chemicals that are acutely toxic and that can be harmful or toxic by ingestion, inhalation, or contact with the skin or eyes, often with a small dose.

41 PICTOGRAMS Etching metal: Another one of Bob’s jobs is to etch metal at one of the buildings to make it look stressed and old. To accomplish that Bob spray’s a corrosive chemical on it. It’s not only corrosive to metal....

42 PICTOGRAMS Corrosives: Chemicals that can be corrosive to metal, skin, or cause damage to eyes can be labeled with this symbol.

43 Personal Protective equipment such as gloves, safety goggles,
PPE PPE: Personal Protective equipment such as gloves, safety goggles, respirators, and specialty chemical protective clothing could have protected Bob from many of these hazards. Our company provides the PPE in the precautionary statements and on the SDS for chemicals our employees work with.

44 PICTOGRAMS Welding: Bob does a little welding in some of the buildings he works on. One is at a public pool built in the 1940s. There is lots of pipe to weld in the pump room, which is where they also store the pool chemicals.

45 PICTOGRAMS FLAME: Flammable solids, gases, aerosols, liquids, or; self-reactive substances and mixtures; pyrophorics, self-heating chemicals; chemicals that ignite when exposed to water and organic peroxides can be depicted with this symbol. GAS CYLINDER: Gases under pressure may explode if heated.This pictogram would be used for compressed gases, liquified gases, refrigerated liquified gases, and dissolved gases. Gases may cause cryogenic burns or injuries.

46 Which becomes a big fire..
PICTOGRAMS FLAME OVER CIRCLE: This symbol represents an oxidizer. Oxidizers are chemicals that cause or help other chemicals to burn by adding oxygen to the chemical process. Oxidizers can be gases, liquids, or solids. To make matters worse, where Bob is welding the pool chemicals are oxidizers... and Bob starts a small fire. Which becomes a big fire..

47 PICTOGRAMS WHICH EXPLODES! EXPLODING BOMB: Explosive; fire, blast or projection hazards by self-reactive substances, substances that can burn without oxygen; or that may explode when disturbed will be labeled with this symbol.

48 PICTOGRAMS Bob next job for this company would been work that cleans up old factories.... ENVIRONMENT: This non-mandatory pictogram represents a chemical’s effect on water, aquatic life or other impacts on the environment. It warns of immediate and long term hazards to the aquatic environment.

49 OUR COMPANIES CHEMICALS
Activity: Think of the types of chemicals our company uses that need pictograms and match them with the correct symbol. Example: Ammonia -

50 Spraying Paints, Primers, or Stains
TASKS THAT INVOLVE CHEMICALS The following activities are where our company uses or hazardous chemicals are present: Spraying Paints, Primers, or Stains Spreading or spraying certain glues Cleaning _____________________________________ _____________________________________________ * Put this list in our Written HAZCOM Plan 36

51 If you have been exposed to a chemical and feel sick:
PROTECTING YOURSELF If you have been exposed to a chemical and feel sick: Let your supervisor know Find out what the chemical was Follow the first aid directions in the SDS Get medical attention as needed Check your PPE before going back to the area “ Obviously, not all sickness is from exposure to chemicals. But if you know you have inhaled a chemical, spilled a chemical on your skin, or ingested some and you feel sick, we want to know. Our intent is to have a safe and healthy workplace and we want to fix any problems.” [Add your company policies here] 50

52 You can get information two ways:
GETTING INFORMATION How do you get information about hazardous chemicals? You can get information two ways: From the product label From the product Safety Data Sheet “ Labels are sketchy and don’t have all the information about the hazards of chemicals in a product. MSDSs usually provide much more information, although it may not always be easy to understand.” 38

53 What is a Safety Data Sheet?
GETTING INFORMATION What is a Safety Data Sheet? Safety Data Sheets (SDS) and Material Safety Data Sheets (MSDS) are information sheets on products that: Tells what chemicals are in the product What the hazards of the chemicals are How to protect yourself from the hazards Safety Data Sheets for our company are located in the following locations Company Office - on the office computer under ______________ and in the book labeled HAZCOM PROGRAM and GHS SDS. On the Job site - in the HAZCOM ADMINISTRATOR’s TRUCK ________________________________________________________ 40

54 What are the features of a SDS? (a) Section 1, Identification;
SAFETY DATA SHEETS What are the features of a SDS? (a) Section 1, Identification; WAC Safety data sheets. (b) Section 2, Hazard(s) identification; (1) Chemical manufacturers and importers must obtain or develop a safety data sheet for each hazardous chemical they produce or import. Employers must have a safety data sheet in the workplace for each hazardous chemical which they use. (c) Section 3, Composition/information on ingredients; (d) Section 4, First-aid measures;

55 What are the features of a SDS?

56 What are the features of a SDS? (12-15 Non-mandatory)
SAFETY DATA SHEETS What are the features of a SDS? (12-15 Non-mandatory) (l) Section 12, Ecological information; (m) Section 13, Disposal considerations; (n) Section 14, Transport information; (o) Section 15, Regulatory information; and (p) Section 16, Other information, including date of preparation or last revision.

57 You can protect yourself from hazardous chemicals by:
PROTECTING YOURSELF You can protect yourself from hazardous chemicals by: Knowing what is in the product your work with Using the smallest amount of a chemical to do the job Wearing necessary personal protective equipment “When using chemicals, more is not always better. Smaller amounts mean less goes into the air and less is spilled or splashed. “ Equipment needs to be maintained to prevent or minimize leaks or releases of chemicals into the work area” 47

58 In the case of a leak or spill, protect yourself by:
PROTECTING YOURSELF In the case of a leak or spill, protect yourself by: Informing your supervisor of unusual odors, spills, or releases Leaving an area of a large spill or chemical release Call ___________ and explain the circumstances of the spill. In addition, our company has this policy: _________________________________________ “Don’t ignore any unusual odors, or stronger than normal odors. This may indicate a leak or release, or if you are wearing a respirator, it may indicate a poor fit, a leak or a used up cartridge. Large leaks, spills or release of a chemical may overwhelm your respirator. Don’t be a hero, get help and proceed cautiously or let the experts clean up the spill.” 49

59 Choose a HAZCOM Administrator and fill out the HAZCOM Program.
HAZARD COMPLIANCE Choose a HAZCOM Administrator and fill out the HAZCOM Program. Make a list of chemicals you have in your workplace. Collect an SDS (MSDS if SDS is not available) for each of the chemicals and put in a book labeled HAZCOM Program and SDS sheets, give employees access. Review the HAZCOM program with your employees. Train employees how to read an SDS, focus on Sections 2,4,6-8. Show employees how to read GHS Product Labels Have proper PPE available for the chemicals which your employees use.
