Recommended Actions: please attach additional documents PUHSD S e p t e m b e r 2 6 , 2 0 1 6 P a g e 39 | 45 Appendix G Chemical-Specific Safety Procedures Reproductive Toxins:  Reproductive toxins should be handled only in a hood, using appropriate protective apparel (especially suitable gloves) to prevent skin contact.  Reproductive toxins should be properly labeled and stored in well-ventilated areas in unbreakable secondary containers, if possible.  Notify supervisor/instructor of all incidents of exposure or spills. High Acute Toxicity Chemicals (Supplemental rules to be followed in addition to those mentioned above):  Use and store these chemicals in areas of restricted access that are posted with special warning signs. These areas should include a hood (with a face velocity of at least 60 linear feet/minute) or other containment device for procedures that may generate aerosols or vapors containing the substance.  Use gloves, long sleeves and other protective apparel as needed to avoid skin contact. Always wash hands after working with these chemicals.  Maintain records of the amounts of these materials on hand, amounts used and the names of the workers involved.  Assure that at least two people are present at all times if a compound in use is highly toxic or of unknown toxicity.  Be prepared for accidents and spills. Store breakable containers of these substances in chemically resistant trays. Cover work and storage surfaces with removable, absorbent, plastic backed paper.  If a major spill occurs outside the hood, evacuate the area; assure that cleanup personnel wear suitable protective apparel and equipment.  Thoroughly decontaminate or incinerate contaminated clothing or shoes. If possibly, chemically decontaminate by chemical conversion.  Store contaminated waste in closed, suitably labeled, secondary containers (for liquids, plastic bottles half-filled with vermiculite). PUHSD S e p t e m b e r 2 6 , 2 0 1 6 P a g e 40 | 45 Select Carcinogens (Further supplemental rules to be followed, in addition to all these mentioned above)  Conduct all transfers and work with these substances in a designated area--a restricted access hood, glove box or portion of a lab designated for use of highly toxic substances, for which all people with access are aware of the substance being used and necessary precautions. The designated area should be conspicuously marked with warning and restricted access signs. Prepare a plan for use and disposal of these materials and obtain approval of the appropriate lab supervisor or instructor.  All containers of these substances should be properly labeled with identity and warning labels.  Store containers of these chemicals in ventilated, limited access areas in appropriately labeled, unbreakable, chemically resistant, secondary containers.  If using toxicologically significant quantities of a select carcinogen on a regular basis (3 times per week or more), consult a physician concerning desirability of regular medical surveillance.  Use a wet mop instead of dry sweeping if the toxic substance was a dry powder.  When using a positive pressure glove box, thoroughly check for leaks before each use. Trap exit gases or filter them through a HEPA filter and then release into the hood.  Use chemical decontamination whenever possible; ensure that containers of contaminated waste (including washings from contaminated flasks) are transferred from the controlled area in secondary container under the supervision of the laboratory supervisor/instructor.  Decontaminate any equipment, including glassware, in the hood before removing them from the controlled area. Decontaminate the controlled area before resuming normal work there.  On leaving the area, remove protective apparel and wash hands, forearms, face and neck. PUHSD S e p t e m b e r 2 6 , 2 0 1 6 P a g e 41 | 45 Flammables:  Never heat flammable liquids with an open flame or hot plate. Use a heating mantle, steam bath or hot water bath.  Never use or store flammable chemicals near any source of ignition spark or open flame.  Handle solvents in an exhaust hood or a well-ventilated area.  Ground containers when transferring from one container to another if the potential for sparking exists.  Do not store large quantities of flammable reagents in the laboratory.  Store flammable liquids in appropriate safety cabinets and/or safety cans.

Precautionary statements

and Operation of Portable Fume Hoods Safety: 1. See the Chemical Guide that came with your model to verify the chemical(s) being used are compatible with the hood filters. If you do not have an Operation Guide check the company’s webpage to download a new manual. 2. Do not use open flame inside the hood. 3. Ensure pre-filters are installed prior to use. Change the pre-filters quarterly. 4. Use care when installing Filter Cells, units are heavy. 5. Exhausted carbon filters have absorbed vapors from chemicals used in the hood and therefore are chemical waste. 6. Users need to be familiar with the operating procedures for the hood. 7. The Chemistry Lab ventilation system must be operating while using the hood. 8. Abnormal odors may indicate that the hood filters may need to be changed. 9. The hood is not intended for highly toxic vapors, unknown reactions, hazardous particulates or experiments generating high levels of contaminants. 10. Minimize the quantity of the chemical(s) used in the hood. 11. Adjust the sash position to the 100 lfps setting for chemicals with TWA’s below 50 ppm. 12. Leave Blower on for at least 1 minute after work in the enclosure has been completed. 13. If a chemical is spilled inside the hood, leave the blower running until all traces of the chemical has been removed. 14. Make sure the Filter Cells are installed prior to using the hood. 15. If the hood blower fails during use, terminate the experiment and evacuate the Lab. PUHSD S e p t e m b e r 2 6 , 2 0 1 6 P a g e 43 | 45 16. For manufacturer’s assistance with the hood or filter selection, contact your manufacturer’s webpage to get assistance or up to date phone numbers to call. Operating the Hood (if hood is equipped): 1. Note: Refer to the hood instructional manual for routine maintenance requirements (see Appendix I) which are dependent upon amount of use and type of chemicals used within the hood. 2. To start the hood, turn on the blower with the switch …. 3. Observe for error messages a. AIR FLOW ERROR – Indicates low air flow b. SENSOR 1 ALARM – Sensor in carbon filter detected a high level of organics c. SENSOR 2 ALARM – Indicates high level of organics in the exhaust ducting d. SENSOR WARM-UP – Sensor warming up. e. MEMORY ERROR - indicates filter hours and other stored times were not stored correctly in memory PUHSD S e p t e m b e r 2 6 , 2 0 1 6 P a g e 44 | 45 Appendix I Routine Maintenance of Portable Fume Hoods Monitoring and changing the filters is the primary maintenance required with this enclosure. Weekly maintenance should be performed by the classroom teacher whereas monthly maintenance should be performed by the Chemical Hygiene Officer (CHO). The teacher can do quarterly pre-filter changes only if they have been trained by the CHO. Under normal operations, your portable fume hood will require little routine maintenance. The following maintenance schedule is recommended: Weekly  Using an appropriate glass cleaner, clean the sash and sides. Wipe down the interior surfaces of the unit using a damp cloth.  Clean the exterior surfaces of the unit, particularly the front and top to remove any accumulated dust. Monthly  Test filter condition using a gas detector tube at intervals of 20% of the total estimated time. The exception to the 20% recommendation is formaldehyde or any carcinogen or suspected carcinogen. These hazardous chemicals must be checked at least every 10% of the total estimated time. Gas detector tubes for the specific chemicals that are being used in the enclosure can be obtained from your laboratory supply dealer.  Check face velocity on the HEPA filtered models. Change HEPA filter when face velocity drops below 90 feet per minute.  Replace filter when chemical breakthrough is indicated by odor, time, detector tube, vapor sensor or for some chemicals, analytical instrumentation.  The Safety First Vapor Senor does NOT eliminate the need to sample with detector tubes. The sensor is capable of detecting organics in the range of 50 ppm. Your chemicals may have TWA’s less than 50 ppm.  See “Filter” section of manual. Quarterly  Change the pre-filters every three months or more frequently if dusty conditions exist. PUHSD S e p t e m b e r 2 6 , 2 0 1 6
