Slide 1: 

Page 1 Hazard Communication Refresher Training

Learning Objectives: 

Learning Objectives Describe the principles OSHA’s Hazard Communications Standard Describe basic elements of chemicals and how they can enter the body Categorize the types of chemical hazards Describe the health and safety effects of exposure to hazardous chemicals Describe the information on a Material Safety Data Sheet (MSDS)

Why OSHA HazCom?: 

Why OSHA HazCom? Employees have a right to know the hazards of the chemicals with which they work. Employees need to know the personal protective measures to take to prevent injury or illness.

Chemicals can exist in three states: 

Page 4 Chemicals can exist in three states And can present different Physical & Chemical properties. For example: Solid Liquid Gas

Physical & Chemical Hazards: 

Page 5 Physical & Chemical Hazards Corrosive: A compound that can quickly damage skin, metal, or other solids Flammability: The ease in which a material (gas, liquid or solid) will ignite Lower Flammable Limit (LFL), or lower explosive limit (LEL), - Upper Flammable Limit (UFL), or upper explosive limit (UEL), - Flash Point: Minimum temperatures at which a liquid or volatile solid will produce gases/vapors to form ignitable mixture Example: Gasoline has a flash point of -45 degree F while diesel fuel has a flash point of 120 degree F.

Health Hazards: 

Page 6 Health Hazards The degree of harm caused by exposure to a chemical Chronic effects Acute effects Some examples of adverse health reactions include: Irritants Corrosives Asphyxiants Respiratory irritants

Chemical Exposure Limits: 

Page 7 Chemical Exposure Limits Defined in two ways: Personal Exposure Limits (PEL) – is a legal limit in the United States for exposure of an employee to a substance or physical agent. Threshold Limit Value (TLV) – defines the reasonable level to which a worker can be exposed without adverse health effects.

Routes of Entry: 

Page 8 Routes of Entry ABSORPTION - contact with the skin or eyes INHALATION - breathing gases, vapors, mists or dusts INGESTION – Intake through the mouth

Control Strategies: 

Page 9 Control Strategies Hierarchy of Controls: Elimination or Substitution Engineering Controls Administrative or Work Practice Controls Personal Protective Equipment PPE is the last choice because it does nothing to reduce the levels of contamination

Hazard Communication Program Requirements: 

Page 10 Hazard Communication Program Requirements Identify and list hazardous chemicals in the workplace Obtain Material Safety Data Sheets (MSDS's) and labels for each hazardous chemical Implement a written HazCom program, including labels, MSDS's, and employee training Communicate hazard information to employees through labels, MSDS's, and formal training programs

Material Safety Data Sheets: 

Page 11 Material Safety Data Sheets The most complete and detailed source of information about any hazardous chemical is the Material Safety Data Sheet. No Standard Format

Material Safety Data Sheet: 

Material Safety Data Sheet MSDS’s must provide information covering key content areas: Manufacturer contact information Chemical Identity Hazardous Ingredients Physical and Chemical Characteristics Fire and Explosion Hazard Data Reactivity (Instability) Data Health Hazards First aid procedures Precautions for Safe Handling and Use Control Measures Do you know where MSDS’s are located?

Chemical Container Labels – Primary: 

Page 13 Chemical Container Labels – Primary Content required Identity of the hazardous chemical or chemicals Name and address of the manufacturer Appropriate hazard warnings, including target organs effects of the hazardous chemical Labels must be legible and prominently displayed No Standard Format!

NFPA Chemical Hazard Labeling Codes: 

Page 14 Health Hazard 4. Deadly 3. Extreme Danger 2. Hazardous 1. Slightly Hazardous 0. Normal Material Fire Hazard Flash Point 4. Below 73 0 F 3. Below 100 0 F 2. Between 100 0 - 200 0 F 1. Above 200 0 F 0. Non-Flammable Instability 4. May Detonate 3. Shock and Heat May Detonate 2. Violent Chemical Change 1. Unstable If Heated 0. Stable Specific Hazard OX Oxidizer ACID Acid ALK Alkali COR Corrosive W Use No Water Radioactive NFPA Chemical Hazard Labeling Codes

In The Event of Exposure : 

Page 15 In The Event of Exposure Always read the label and MSDS for every chemical you work with Emergency procedures may include Eyes: Flush with water for 15 minutes Skin: Remove contaminated clothing and wash affected areas with soap and water, Inhalation: Move to fresh air Swallowing: Get immediate emergency medical assistance Do you know where your eyewash stations, emergency showers, and first-aid kits are located? Do you know how to use them?

Why Use PPE?: 

Why Use PPE? PPE doesn’t work when it’s not worn!

Assessing the Hazard: 

Assessing the Hazard Head Eye & Face Hand Foot Before starting a task, consider the potential hazards involved. If possible, remove the hazard. Do not start a job unless you have adequate PPE!

Types of Hazards: 

Types of Hazards Impact : Anything that could cause a struck by accident Chemical : inhalation and or skin absorption Harmful Dust : Dust or fumes that could be inhaled Compression : Pinching, crushing, breaking Puncture : Cuts, lacerations, contusions Radiation : welding

Training & Information: 

Training & Information When PPE is Necessary What PPE is necessary How to wear assigned PPE Limitations of PPE

When is PPE is necessary?: 

When is PPE is necessary? Eye and face protection are protects against exposure to: • Flying particles • Liquid chemicals • Acids or caustics • Chemical gases or vapors • Potentially harmful light radiation Goggles or Glasses?

When is PPE is necessary?: 

When is PPE is necessary? Head protection : • Falling objects • Cranes • Overhead equipment • Employees working above them Where do we need it?

When is PPE is necessary?: 

When is PPE is necessary? Workers must wear gloves if: • Harmful substances are present • Chemical or thermal burns could occur • Temperatures are extreme • Cuts, lacerations or abrasions could occur What’s a good glove?

When is PPE is necessary?: 

When is PPE is necessary? Hearing protection is required: Noise above 85 decibels, Can’t hear the person next to you Foot protection is required when exposed to heavy falling objects or struck by equipment.

Maintaining Your PPE: 

Maintaining Your PPE It is important that all PPE be kept clean and properly maintained by the employee using it. Cleaning is very important for eye protection as dirty lenses could impair your vision.

Hand Protection Tips: 

Gloves must be inspected prior to each use. Care must be taken when removing gloves not to contaminate bare skin with chemical residue. The inside of impermeable gloves should be cleaned via ordinary soap/water as needed. Disposable sanitary gloves should be worn under shared gloves. Hand Protection Tips

Limitations of PPE: 

Limitations of PPE PPE will not make you super human PPE is just one solution used to address safety concerns and make the workplace safer. Other solutions, such as engineering controls or eliminating the hazard (when possible) are preferable Always observe safety rules Think before you do. Nobody comes to work to get hurt and no one should.
