  1. HAZARDOUS MATERIALS 1 0 3 SAFE CHEMICAL HANDLING

  2. SAFE CHEMICAL HANDLING OSHA TRAINING OSHA 29 CFR 1910 WELCOME

  3. BASIS FOR THIS COURSE THE BOTTOM LINE TRAINING YOU TO BE KNOWLEDGEABLE OF HOW TO LOWER YOUR LIFETIME WORKPLACE EXPOSURE AND DOSAGE TO THE CHEMICALS AND TOXIC MATERIALS YOU ARE POTENTIALLY EXPOSED TO IN YOUR DAILY WORKING LIFE!

  4. FLAMMABLE LIQUID FLAMMABLE LIQUID ETHYLMETHYL NASTY ETHYLMETHYL NASTY REGULATORY STANDARD FLAMMABLE AND COMBUSTIBLE LIQUIDS 29CFR - 1910 - 106 • 29CFR - SAFETY AND HEALTH STANDARDS • 1910 - GENERAL INDUSTRY • 106 - FLAMMABLE AND • COMBUSTIBLE LIQUIDS

  5. REGULATORY STANDARD HAZARD COMMUNICATION 29CFR - 1910 - 1200 29CFR - SAFETY AND HEALTH STANDARDS 1910 - GENERAL INDUSTRY 1200 - HAZCOM STANDARD

  6. PERSONAL PROTECTIVE EQUIPMENT • PERSONAL PROTECTIVE EQUIPMENT REQUIREMENTS: • Follow Local Job Procedures. • Review the Relative Material Safety Data Sheet. • If You Have Questions Consult Your Supervisor.

  7. GENERAL CONCEPTS OF TOXICOLOGY EVERYTHING IS TOXIC; IT ALL DEPENDS ON THE DOSE • HOW WELL THE BODY ACCEPTS A SUBSTANCE DEPENDS ON: • THE TYPE OF SUBSTANCE • THE AMOUNT (DOSE) ABSORBED • THE PERIOD OF TIME OVER WHICH IT IS ABSORBED • THE SUSCEPTIBILITY/SENSITIVITY OF THE PERSON EXPOSED

  8. GENERAL CONCEPTS OF TOXICOLOGY • DEGREE OF HARM TO BODY DEPENDENT ON: • CONDITIONS OF USE • PHYSICAL PROPERTIES OF THE CHEMICAL • ROUTES OF EXPOSURE • DURATION OF THE EXPOSURE • CONCENTRATION OF THE CONTAMINANT IN AIR • INDIVIDUAL SUSCEPTIBILITY OF THE EXPOSED PERSON • TOXICITY OF THE CHEMICAL

  9. SOLID LIQUID GAS STATES OF MATTER • CHANGE OF STATE CAN OCCUR DUE TO: • HEAT • COLD • ATMOSPHERIC PRESSURE • INTERACTION WITH OTHER CHEMICALS

  10. STATES OF MATTER • AIRBORNE CONTAMINANTS: • FUME • DUST • MIST • VAPOR • GAS • SMOKE

  11. TYPES OF PROCESSES • OPEN • CLOSED

  12. CLOSED • OPEN • PLATING • DEGREASING • PARTS PAINTING • REFINING • DISTILLING • GAS PRODUCTION TYPES OF PROCESSES

  13. HAZARDS: • PRESSURE • EXPLOSION • FIRE • TOXICITY • CORROSIVITY • REACTIVITY HANDLING GASES

  14. HANDLING GASES GASES - PRE-OPERATION SAFETY 1. Inspect cylinder for damage before use. 2. Ensure “in use” label is present. 3. Ensure all labels and warnings are readable. 4. Place upright on stable dry surface. 5. Ensure cylinder is restrained above mid-point. 6. Keep heat, flame, and electricity away from cylinder. 7. Operate in accordance with local safety procedures.

  15. HANDLING GASES GASES - POST-OPERATION SAFETY 1. Ensure “empty” or like label present. 2. Remove from operation following procedures. 3. Ensure valve closed completely and cap cylinder. 4. Never roll, transport cylinders using handtruck. 5. Never underestimate hazards associated with compressed gases.

  16. STORING GASES • GASES - STORAGE REQUIREMENTS • Store only in designated areas. • Store and use on a first-in, first-out basis. • Never store without proper labeling. • Identify all empty cylinders. • Store like gases with like gases. • Separate empty cylinders from full ones. • Store within proper temperature ranges.

  17. STORING GASES • GASES - STORAGE REQUIREMENTS • Store outside when possible. • Protect from weather and direct sunlight. • Ensure storage areas meets guidelines. • Never store where temperature can rise to 130f. • Place caps on stored cylinders. • Store valve end up in a secure area. • Inspect and properly tag defective cylinders.

  18. STORING GASES • THE BOTTOM LINE • Follow all safety guidelines. • Review current storage requirements. • Know - compressed gas association rules. • Know - NFPA rules. • Know - OSHA rules. • Know - the local policy. • Never underestimate compressed gases!

  19. HANDLING IGNITABLE LIQUIDS • TYPES AND DEFINITIONS: • Flashpoint - minimum ignition temp. for ignitable vapor • Flammable - flashpoint below 100 deg. (F.) • Combustible - flashpoint at or above 100 deg. (F.) • Pyrophoric - can ignite spontaneously • Flammable range - vapor/air ratio that will burn • Volatility - tendency to change to vapor state

  20. SOLVENT OXIDIZER HANDLING IGNITABLE LIQUIDS CHECK FOR COMPATIBILITY!

  21. FLAMMABLE LIQUIDS STORING IGNITABLE LIQUIDS STORING FLAMMABLE AND COMBUSTIBLE LIQUIDS: • LEVELS OF STORAGE: • HAZARDOUS MATERIALS STORAGE FACILITY • IN-PLANT STORAGE CABINETS • TOTES, DRUMS/BARRELS • PORTABLE CONTAINERS

  22. FLAMMABLE LIQUIDS STORING IGNITABLE LIQUIDS • HAZARDOUS MATERIALS STORAGE FACILITY • Dedicated fire suppression system • Make-up air • Exhaust ventilation • Explosion-proof lighting and heating • Floor drains • 2-Hour fire rating on structure • Proper signage and safety procedures

  23. FLAMMABLE LIQUIDS STORING IGNITABLE LIQUIDS • TOTES, DRUMS AND BARRELS • Should be moved to storage ASAP • Make best use of just-in-time system • Bonding wires must be used • Local fire codes must be considered • Bonding - container to container • Grounding - container to structural ground • No ignition sources within 25 feet

  24. FLAMMABLE LIQUIDS STORING IGNITABLE LIQUIDS • PORTABLE CONTAINERS • Bond from drum to container during transfer • Store in safety cabinets when not in use • Check for leak-tightness • Check for serviceable vent mechanism • Do not remove flame arrester screens • Do not overfill (high temps will cause overflow) • Follow warnings and safety procedures

  25. GENERAL SAFETY PRECAUTIONS • Remove electrical equipment • Use spark resistant tools • Use safe techniques to move containers • Use proper dispensing faucets • Follow warnings and use labels • Properly dispose of empty containers • Follow proper inspection procedures FLAMMABLE LIQUIDS STORING IGNITABLE LIQUIDS

  26. ACIDS BASES OXIDIZERS HANDLING CORROSIVE LIQUIDS • AFFECT OTHER MATERIALS BY CONTACT: • Acids and bases affect material by contact • Acids and bases affect each other • Oxidizers increase hazard during fires

  27. OXIDIZER HANDLING CORROSIVE LIQUIDS DOT DEFINITION OXIDIZER A material such as a chlorate, permanganate, or inorganic peroxide that will give off oxygen readily to stimulate the combustion of organic material.

  28. OXIDIZER HANDLING CORROSIVE LIQUIDS • OXIDIZERS • Provide oxygen for combustion • React violently with flammables and combustibles • Must be kept separate from all other classes of materials

  29. CORROSIVE MATERIALS HANDLING CORROSIVE LIQUIDS • DOT DEFINITION • CORROSIVE A liquid or solid that causes visible Destruction or irreversible damage To skin tissue at the point of contact, Or that has a severe corrosion rate on steel.

  30. ACID HANDLING CORROSIVE LIQUIDS OSHA DEFINITION CORROSIVE A chemical that causes visible destruction of, or irreversible alterations in living tissue by chemical action at the site of contact.

  31. HANDLING CORROSIVE LIQUIDS • ACIDS AND BASES • - pH. THE pH OF A LIQUID IS THE NUMERICAL MEASURE • OF ITS RELATIVE ACIDITY OR ALKALINITY. THE RANGE • IS FROM 0 - 14 WITH A NEUTRAL LEVEL EXPRESSED AS • A pH OF 7.0. • ABOVE 7.0 THE LIQUID IS MORE ALKALINE OR BASIC. • BELOW 7.0 THE LIQUID IS MORE ACIDIC.

  32. BASE ACID HANDLING CORROSIVE LIQUIDS ACIDS AND BASES • COMMON ACIDS (pH 0-6) • HYDROCHLORIC ACID • HYDROFLUORIC ACID • NITRIC ACID • PHOSPHORIC ACID • CHROMIC ACID • COMMON BASES (pH 8-14) • SODIUM HYDROXIDE (LYE) • SODIUM HYPOCHLORITE (BLEACH) • AQUEOUS AMMONIA • POTASSIUM HYDROXIDE (POTASH) • AMMONIUM HYDROXIDE
