peroxides in accordance with the timetable found in Appendix C. Dates of tests must also be recorded on the container label. • Flammable liquids in excess of quantities for specific flammability classes must be stored in approved flammable liquid storage cabinets. • Do not store corrosive or other chemicals that can be injurious to the eyes above eye level. In general and where practical, no chemicals should be stored above eye level. • Do not store flammable liquids in standard (non-explosion proof) refrigerators or freezers. Because of the potential explosion hazard, only store flammables in refrigerators or freezers approved by the manufacturer for storage of flammables. • Highly toxic chemicals should be stored in locked storage cabinets. Always keep the quantities of highly toxic chemicals to an absolute minimum (see the Particularly Hazardous Substances section). • Be aware of any special antidotes or medical treatment that may be required for some chemicals (such as cyanides and Hydrofluoric acid). • Organic and mineral acids must be stored separately • Always keep spill kits and other spill control equipment on hand in areas where chemicals are used. Ensure that all personnel working in the lab have been properly trained on the location and use of the spill kit. • For reagents, use shelves with anti-roll lips to prevent bottles from falling. This can also be accomplished by using heavy gauge twine or wire to create a lip on the shelf. • Labels must be maintained on all stored materials. New labels must be created for secondary containers used for transport. • Stored chemicals should be in amber bottles and must not be exposed to direct sunlight or heat. • Storage trays should be used to minimize the spread of a spill. • Laboratory refrigerators must never be used to store food. • All chemical containers left out of storage areas must be checked at the end of each workday. Unneeded items must be returned to chemical storerooms or stockrooms. Dates must be assigned to all chemical containers in the following groups when they are initially opened by the first laboratory employee using them. · Picrics · Perchlorates · Peroxides 31
· Peroxidizable materials (aldehydes, ethers, and compounds containing benzylic hydrogen atoms, e.g., cumene isopropyl benzene and most alkene, vinyl, and vinylidene compounds) · Polymerizers that react violently in polymerization or become hazardous after polymerization · Other materials known to deteriorate or become unstable or reactive over time Expiration dates must be assigned to these chemicals. When provided, the manufacturers' expiration date should be displayed. Peroxidizable materials must be tested routinely for peroxides. (See the table "Common Peroxide Forming Chemicals' in Appendix C for a more complete list of these chemicals and testing instructions.) • All laboratory personnel, upon notice of retirement, termination, transfer, or graduation, must in conjunction with the laboratory supervisor and Chemical Hygiene Officer, arrange for the removal or safe storage of all hazardous materials remaining in their laboratory. • Appropriate spill control, cleanup, and emergency equipment must be available wherever chemicals are stored. See Chapter VIII for considerations in choosing these materials. 6.3 Chemical Storage Limits The nature of laboratory work calls for a certain amount of chemicals to be on hand for easy access. However, all laboratory employees must limit, as much as possible the amounts of chemicals stored on bench tops, in hoods, under sinks or other exposed areas, especially when these chemicals are flammable, combustible, reactive, toxic, or corrosive. 1. Legal limits on amounts of flammables, combustibles, reactives, and unstable chemicals in laboratories. Local fire regulations (such as those in New York City) determine the amount of flammable materials or oxidizing, unstable, and reactive chemicals that may be stored in laboratories based on the fire rating of the room and whether it has a sprinkler system. The following table shows an example of local fire department limits in New York City. These reflect the new revisions established in 2009. NFPA 45, Table 10.1.1 as modified by FC 2706 Flammable & Comb Liquids Class Excluding quantities in storage cabinets (any fire rating); Total allowable amount stored outside of an approved flammable cabinet Maximum Qty/100 ft2 of lab unit Maximum Qty per lab unit Including quantities in storage cabinets AND a minimum 2-hr laboratory fire rating; All amounts stored inside flammable cabinets Maximum Qty/100 ft2 of lab unit Maximum Qty per lab unit D I 1 gallon 75 gals* 2 gals D I, II & III 1 gallon 75 gals* 2 gals 150 gals** 150 gals** B I 5 gallons 25 gals 10 gallons 30 gals B I, II & III 10 gallons 25 gals 20 gallons 30 gals * Increased to 100 gals if not an educational or instructional lab as per FC 2706.6 32
