Material Safety Data Sheets (MSDS)
Primary resource for chemical hazard communication For every hazardous chemical Available online Locator poster required Standard information required by the regulation will be contained in the MSDS
Information in MSDS
Substance Identification and Synonyms Hazardous Components (if mixture) Physical Data: appearance, melting point Fire & Explosion Data: flash-point, LEL Toxicity Data: LD50’s, carcinogenicity Health Effects & First Aid Reactivity: incompatibilities Storage & Disposal Procedures Spill & Leak Procedures Protective Equipment
Health Hazard Definitions
Carcinogen: Causes cancer Corrosive: Causes visible destruction of living tissue by chemical action Irritant: Causes reversible inflammatory effect on living tissues Sensitizer: Causes most people to develop an allergic reaction after repeated exposure Toxic: Poisonous
Target Organ Effects Hepatotoxins: Liver damage Neurotoxins: Nervous system damage Nephrotoxins: Kidney damage Hematopoietic: Blood function/production damage Pulmonary Hazard: Damages the lung Cutaneous Hazard: Affects/damages skin Ocular hazards: Affects eye or visual capacity Reproductive toxins: Teratogen: Impacts developing fetus Mutagen: Impacts DNA
Factors Affecting Chemical Exposure
Amount and toxicity of chemical Duration and frequency of exposure Route of entry Hazard controls (Engineering, Administrative and PPE)
Control of Hazards
Engineering Controls Substitution Isolation Ventilation Administrative Controls
Name: CUIZON, Drew Avinash C. Cuizon Section: EE-2A Subject: Basic Occupational Health and Safety Assignment #: 8
Purpose of the Laboratory Safety Standard
To reduce or eliminate the risk of exposure to employees from hazardous chemicals in the laboratory
Chemical Hygiene Plan (CHP)
Review before working in the laboratory If unavailable please see your supervisor Labs must customize the CHP notebook section
Chemical Hygiene Plan (CHP) Components
Chemical List Standard Operating Procedures Material Safety Data Sheets Emergency Preparedness General and Specific Training Specific Waste Disposal Methods Personal Protective Equipment Inspections and Exposure Monitoring
Standard Operating Procedure (SOP)
Written for an individual hazardous chemical or method using that chemical and includes: Hazardous properties of chemical Proper chemical storage PPE (gloves, glasses, etc.) Proper location to perform procedure Proper waste disposal Accident and spill reporting Equipment hazards and precautions
Compressed Gas Cylinders
Always secure in an upright position Use valve protection caps Properly label cylinder Name of gas Type of gas (Oxidizer, Flammable, etc.) Current status "Full or Empty" Do not store flammable gasses near ignition sources or oxidizers Do not block access to cylinders Do not run hoses throughout lab
Safe Chemical Storage
Separate stored chemicals by compatibility: (acid, base, flammable, oxidizer) Store bulk flammable liquids in a Flammable Liquid Storage Cabinet Refrigerate flammable chemicals only in a unit designed for that purpose To redistribute unopened chemicals, call OSEH HazMat at 3-
Emergency Preparedness
Rule of thumb - Plan ahead!! Evacuate the lab Shut door & post restriction if necessary Activate alarm & call 911 Implement emergency response plan for your unit
Emergency Response
Ventilation failures Plumbing leaks Power failures Fires and explosions Spill control and clean-up Personal injury and exposure
Name: CUIZON, Drew Avinash C. Cuizon Section: EE-2A Subject: Basic Occupational Health and Safety Assignment #: 8
Chemical Waste Disposal: What can go down the sink?
Bleach and other disinfectants Blood and blood-products Detergent and other cleaners Buffers, isotonic saline solutions, or non-hazardous liquid media, acids/bases with a pH between 5- 10
Hazardous Chemical Waste Management
Properly store compatible waste Use secondary containment when
10 gallons Pack in a suitable container for transportation Affix completed “Hazardous Waste” label listing chemicals in the container Make sure the container is closed and sealed
Hazardous Chemical Waste Labeling
EPA ID Number: MI Manifest Number Generator Information Chemical Description of Hazardous Waste Accumulation Start Date
Hazardous Chemical Waste Labeling
Label ALL hazardous waste containers
Tips for Fume Hood Use
Check that the hood is operating correctly Use the sash to protect yourself Keep sash at the certification mark Check that the hood is operating correctly Use the sash to protect yourself Keep sash at the certification mark
Additional Safety Precautions
Know location of Emergency Shower and Eyewash (100 feet/ second rule) Know location of Fire Response Equipment No eating or drinking in laboratories Do NOT store food in laboratory refrigerators; label with appropriate sign Frequent hand washing recommended
1. Produced by flow of electrical current through ionized air after an initial flashover or short circuit. Arc 2. Arcs produce some of the highest temperatures known to occur on earth – up to. 35000 F 3. All known materials are ______ at this temperature. Vaporized 4. Arc Flash Effects: Burn from intense heat Trauma from blast pressure Toxic gases from vaporized metal Sprayed molten metal droplets Hearing damage from sound pressure wave Eye damage 5. Elements of Arc Flash Safety: Defined responsibilities Calculation of degree of arc flash hazard Personal protective equipment Training Tools for safe work Warning labels on equipment 6. Determines flash protection boundary and PPE requirements as a function of location and work activity. Arc Flash Hazard Analysis 7. Arc flash hazard and flash protection boundary varies with: Type of equipment and configuration Available short circuit current Voltage Predicted fault duration 8. Linear distance from exposed live parts within which a person could receive second degree burns resulting from an arc flash. Flash Protection Boundary 9. Entered only by qualified persons or unqualified persons escorted by qualified person. Limited Approach Boundary 10. Entered only by qualified persons required to use shock protection techniques and equipment. Restricted Approach Boundary 11. Entered only by qualified persons requiring same protection as if in direct contact with live parts. Prohibited Approach Boundary
12. Each boundary is a sphere to be observed in all directions three dimensionally. Approach Boundaries 13. Switchboards, panel boards, industrial controls, etc. that require examination, adjustment, or maintenance while energized shall be ___. Labeled 14. Two types of arc flash hazard labels: Low voltage below 680 volts High voltage above 680 volts 15. Types of Insulated Tools Flame retardant Double insulated 16. A first hi-visibility yellow layer provides the insulation for the tool, and the outer hi- visibility orange layer protects the lower yellow layer. Double insulated 17. Electrically safe working Conditions Determine all electrical sources using up-todate information, drawings, diagrams, etc. After properly interrupting the load current, open the disconnecting device(s) for each source. Visually verify that disconnecting means fully open if possible. Apply lockout tagout devices Test for absence of voltage Ground phase conductors if there is a possibility of induced voltages or stored energy 18. Safe work practices: Use of insulated tools Use of personal protective equipment Not working alone 19. PPE required for 120 volts: Safety glasses Cotton shirt and pants 20.
