1 Hazard Communication University of Southern Maine Environmental Health and Safety

2 Training Outline Federal Laboratory Standards Hazards at USM Material Safety Data Sheets (MSDS) Chemical Toxicology Personal Protective Equipment (PPE) Emergency Procedures Chemical Storage/Disposal

3 What is Hazard Communication? Defined under two Occupational Safety and Health Administration (OSHA) regulations Hazard Communication Standard 29 CFR Promulgated 25 November 1983 Occupational Exposure to Hazardous Chemicals in Laboratories 29 CFR Promulgated 1 May 1990

4 Hazard Communication Purpose To ensure that the hazard of all chemicals produced are evaluated and that the information is transmitted to employees. Accomplished via: Container labeling Material Safety Data Sheets (MSDS) Employee training

5 Laboratory Standard Purpose Provide employees with the necessary tools to protect themselves and their co-workers. Accomplished via: Knowledge Personal Protective Equipment (PPE) Engineering Controls

6 Responsibilities of UEH&S Chemical Hygiene Plan: A program documenting procedures, personal protective equipment, and work practices that are capable of protecting the employee from the health hazards used in that particular work place. Protect employees from health hazards associated with hazardous chemicals. Keep exposure levels below the permissible exposure limit (PEL).

7 Responsibilities of UEH&S Employees have a right-to-know about the chemical hazards which they may be exposed to. Collect MSDS and make them available to all employees. Provide training to all employees with potential exposure to hazardous materials.

8 Employee Responsibilities Attend training classes. Learn the chemical hazard by reading the MSDS. Know the signs and symptoms of exposure. Know the proper personal protective equipment (PPE) to use. Know emergency procedures.

9 Employee Rights Request and obtain information on hazardous chemicals in your workplace. Be informed of hazardous chemicals you come in contact with on your job. Access to written material. MSDS Chemical Hygiene Plan Hazardous Communication

10 Hazards at USM Chemical There are many different chemicals on campus. Flammable Example: Xylene, Ethanol Corrosive Example: Nitric Acid Reactive Example: Sodium Biological Examples: Allergens, Infectious Diseases, Toxins Radiation Laser or radioactive material.

11 Hazards at USM: Select Definitions Carcinogens Cancer causing Mutagens Genetic effects Teratogens Congenital Fetus Neurotoxic Nervous system Nephrotic Kidney/Liver Hepatic Liver

12 Hazards at USM Cancer causing Asbestos, Benzene, Cadmium Mutagens - Vinyl chloride, Urethane Teratogens Lead, Dioxins Neurotoxic Arsenic, Barium, DDT, Lead, Mercury Nephrotic Chloroform, Cadmium, Mercury, Lead Hepatic Alcohol, Beryllium, Botulinum toxins

13 Hazards at USM National Fire Protection Association (NFPA) Diamond A system for identifying the hazards associated with materials. Designed for emergencies when information about exposure is needed.

14 Hazards at USM HMIS (Hazardous Material Identification System) Numerical hazard rating system. Uses labels with color-coded bars. Not for emergencies, conveys broader health warning information. Has physical hazard bar (orange) rather than reactivity.

15 HMIS Rating System

16 HMIS Rating System

17 HMIS Rating Sytem

18 Hazards at USM Physical Temperature Extremes Electrical Fire Examples: Methanol Explosions Examples: Picric Acid Cryogenic Liquids Compressed Gasses

19 Hazards at USM Cryogenic Liquids Compressed Gas Cylinders

20 Signs and Labels

21 Signs and Labels

22 Signs and Labels

23 Material Safety Data Sheets (MSDS) A document provided by the manufacturer that contains information on the potential hazards and how to work safely with the chemical product. Should be able to provide one to any inspector or person who asks. Common website:

24 Material Safety Data Sheets (MSDS) Manufacturer s Info Name, address and phone number Common names Hazardous Ingredients Hazard Characteristics Routes of entry Physical hazards Health hazards First Aid Measures Fire Fighting Measures Accidental Release Handling and Storage Exposure Control Personal Protective Equipment Acceptable Exposure Levels Chemical Information/Toxicology

25 Labeling Manufacture label Chemical name Appropriate warnings. Name and address of manufacturer. In-house label Chemical name Appropriate warnings

26 Chemical Toxicology Toxicology is the study of how chemicals cause undesirable effects on humans. Signs and Symptoms of Exposure Know the signs and symptoms associated with exposure to the chemicals in your workplace. Be observant for these signs and symptoms. Know what to do if you are exposed.

27 Chemical Toxicology Routes of Entry Inhalation Absorption Ingestion Injection

28 Chemical Toxicology Inhalation The most common route of exposure. Can be in the form of a gas, vapor or dust. Example: Formaldehyde Can be deposited in the airways or absorbed through the lungs and into the blood stream. Blood can then circulate the toxin to the rest of the body.

29 Chemical Toxicology Absorption Skin acts as a barrier between the environment and the organs of the human body. Skin can be attacked directly. Examples: Acids and Bases Skin can be penetrated. Examples: Phenol, Nitrobenzene

30 Chemical Toxicology Ingestion Deliberate swallowing of toxic substances. Food and drinks can become contaminated by dust, mist and fumes. Dust on hands, face and clothing can get into the mouth by licking one s lips or wiping one s face.

31 Chemical Toxicology No eating or drinking in laboratories or storing food in laboratory refrigerators or cold rooms.

32 Chemical Toxicology Injection Occurs through accidental needle sticks, puncture wounds or through broken skin / open wounds. May produce rapid response when injected because the chemical / toxin is introduced directly into the blood stream.

41 Emergency Procedures Remain calm. Protect yourself and you colleagues from further harm. Notify UEH&S, USM Police, and/or Fire Department as appropriate. Wash any chemical contact for >15 minutes. Seek medical attention if needed.

42 Chemical Storage / Disposal Order only what is needed. Make sure chemicals are labeled properly. Avoid floor and top shelf storage. Store flammables in appropriate cabinets.

43 Chemical Storage / Disposal Separate acids and bases. Example: Sulfuric Acid and Sodium Hydroxide Nitric acid must isolated from other acids and bases. Segregate oxidizers from organic liquids. Examples: Dinitrogen Dioxide, Perchlorates, Permanganates, Silver Nitrate Dispose of used / expired chemicals via UEH&S. Examples: Peroxides, Ether, 2-Propanol

44 Chemical Storage / Disposal Acid Storage Flammable Storage

45 Chemical Storage / Disposal Chemical disposal is free. Do not evaporate chemicals in the fume hood. Use the proper waste container. Examples: Sharps, Ethidium Bromide gels, Radioactive, Office waste, Recycle waste. Rinse empty bottles and deface label. Label all chemical waste.

46 Summary MSDS are available to anyone. Understand the hazards of the chemicals you work with. Wear the appropriate PPE. Always use a chemical fume hood. Keep the work area clean. Rinse affected area for at least 15 minutes. Call UEH&S with any questions
