your P.I., thoroughly read the MSDSs and any other chemical resources related to the potentially explosive compound(s) to minimize hazards. Whenever setting up experiments using potentially explosive compounds: • Always use the smallest quantity of the chemical possible. • Always conduct the experiment within a fume hood and properly rated safety shield. • Be sure to remove any unnecessary equipment and other chemicals (particularly highly toxic and flammable) away from the immediate work area. • Be sure to notify other people in the laboratory what experiment is being conducted, what the potential hazards are, and when the experiment will be run. • Do not use metal or wooden devices when stirring, cutting, or scraping with potentially explosive compounds. Non-sparking plastic devices should be used instead. • Ensure that other safety devices such as high temperature controls and water overflow devices are used to help minimize any potential incidents. • Dispose of any hazardous waste properly and note on the hazardous waste tag any special precautions that may need to be taken if the chemical is potentially explosive. • Always wear appropriate PPE, including the correct gloves, lab coat or apron, safety goggles used in conjunction with a face shield, and explosion-proof shields when working with potentially explosive chemicals. • For storage purposes, always date chemical containers when received and opened. Pay particular attention to those compounds that must remain moist or wet so they do not become explosive (e.g., Picric acid or 4-Dinitrophenyl hydrazine). Pay particular attention to any potentially explosive compounds that appear to exhibit the following signs of contamination: • Deterioration of the outside of the container. • Crystalline growth in or outside the container. • Discoloration of the chemical. If you discover a potentially explosive compound that exhibits any of these signs of contamination, contact your EHSO for assistance. Examples of explosive and potentially explosive chemicals include: • Compounds containing the functional groups azide, acetylide, diazo, nitroso, haloamine, peroxide, and ozonide • Nitrocellulose • Di- and Tri-nitro compounds • Peroxide forming compounds 41
• Metal Picrate Salts • 2,4-Dinitrophenylhydrazine (dry) • Benzoyl peroxide (dry) • Metal Perchlorate Salts 7.2 Flammable and Combustible Liquids The OSHA Laboratory Standard defines a flammable liquid as any liquid having a flashpoint below 100 degrees F (37.8 degrees C), except any mixture having components with flashpoints of 100 degrees F (37.8 degrees C) or higher, the total of which make up 99% or more of the total volume of the mixture. Flashpoint is defined as the minimum temperature at which a liquid gives off enough vapor to ignite in the presence of an ignition source. The risk of a fire requires that the temperature be above the flashpoint and the airborne concentration be in the flammable range above the Lower Explosive Limit (LEL) and below the Upper Explosive Limit (UEL). The OSHA Laboratory Standard defines a combustible liquid as any liquid having a flashpoint at or above 100 degrees F (37.8 degrees C), but below 200 degrees F (93.3 degrees C), except any mixture having components with flashpoints of 200 degrees F (93.3 degrees C), or higher, the total volume of which make up 99% or more of the total volume of the mixture. OSHA further breaks down flammables into Class I liquids, and combustibles into Class II and Class III liquids. Please note this classification is different than the criteria used for DOT classification. This distinction is important because allowable container sizes and storage amounts are based on the particular OSHA Class of the flammable liquid. Classification Flash Point Boiling Point Flammable Liquid Class IA =100 degrees F, =140 degrees F, < 200 degrees F -- Class IIIB >=200 degrees F -- Under the Department of Transportation (DOT) hazard class system, flammable liquids are listed as hazard class 3. Flammable and combustible liquids are commonly used at QCC and are important in a number of laboratory processes. However, in addition to the flammable hazard, some flammable liquids also may possess other hazards such as being toxic and/or corrosive. When using flammable liquids, keep containers away from open flames; it is best to use heating sources such as steam baths, water baths, oil baths, and heating mantels. Never use a heat gun to 42
