Schools may wish to devise a simple color-coding scheme to address this problem. The code shown below, reproduced with permission from School Science Laboratories-A Guide to Some Hazardous Substances by the Council of State Science Supervisors, includes both solid and striped colors which are used to designate specific hazards as follows: Red - Flammability hazard: Store in a flammable chemical storage area. Red Stripe - Flammability hazard: Do not store in the same area as other flammable substances. Yellow - Reactivity hazard: Store separately from other chemicals. Yellow Stripe - Reactivity hazard: Do not store with other yellow coded chemicals; store separately. White - Contact hazard: Store separately in a corrosion-proof container. White Stripe - Contact hazard: Not compatible with chemicals in solid white category. Blue - Health hazard: Store in a secure poison area. Orange - Not suitably characterized by any of the foregoing categories. -

INFORMATION TO USERS While the most advanced technology has been used to photograph and reproduce this manuscript, the quality of the reproduction is heavily dependent upon the quality of the material submitted. For example: # Manuscript pages may have indistinct print. In such cases, the best available copy has been filmed. ® Manuscripts may not always be complete. In such cases, a note will indicate that it is not possible to obtain missing pages. ® Copyrighted material may have been removed from the manuscript. In such cases, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, and charts) are photographed by sectioning the original, beginning at the upper left-hand corner and continuing from left to right in equal sections with small overlaps. Each oversize page is also filmed as one exposure and is available, for an additional charge, as a standard 35mm slide or as a 17”x 23" black and white photographic print. Most photographs reproduce acceptably on positive microfilm or microfiche but lack the clarity on xerographic copies made from the microfilm. For an additional charge, 35mm slides of 6”x 9” black and white photographic prints are available for any photographs or illustrations that cannot be reproduced satisfactorily by xerography.

Hot Plate Safety
LABORATORY SAFETY GUIDELINE Hot Plate Safety Hot plates used in labs present many potential dangers, such as burns, fires, and electrical shock, which can cause injuries, significant disruption of lab operations, and loss of scientific data. Burns • The hot plate is a source of heat when on, and for some time after it has been turned off. The temperature of the heated plate can reach 500°C and can cause severe burns. Electric Shock • Touching the hot plate with the power cords can melt through the insultation and cause electric shock. Fire Hazard • Electrical spark hazard from either the on-off switch or the bimetallic thermostat used to regulate temperature, or both, are a design flaw issue in older hotplate models. If the equipment sparks near combustible or flammable materials, fire could result. • Exercise caution when heating flammable materials. • Hot/stirrer plates have an additional risk if an operator accidentally turns on the wrong feature. • Hot plates are NOT explosion proof or intrinsically safe. Basic Precautions: • Only use hot plates that have been approved by a Nationally Recognized Testing Laboratory (NRTL) such as Underwriter’s Laboratory (UL). • Read the manufacturer’s instructions before using and consider registering the device with the manufacturer so you will be notified of any warnings or recalls. • Periodically inspect equipment prior to use: o Do not use if the plug or cord is worn, frayed, or damaged, if the grounding pin has been removed, or if a spark is observed. o Check for corrosion of the thermostat, which can cause a spark. o Test the function of the “off” switch on each hot plate to verify that it works and the device cools quickly when the switch is in the “off” position. -

Correspondence should be addressed to E.T. ([email protected]) or R.K. ([email protected]). Published online 21 February 2013; doi:10.1038/nprot.2013.021 We present a protocol for building and operating an automated fluidic system for continuous culture that we call the ‘morbidostat’. The morbidostat is used to follow the evolution of microbial drug resistance in real time. Instead of exposing bacteria to predetermined drug environments, the morbidostat constantly measures the growth rates of evolving microbial populations and dynamically adjusts drug concentrations inside culture vials in order to maintain a constant drug-induced inhibition. The growth rate measurements are done using an optical detection system that is based on measuring the intensity of back-scattered light from bacterial cells suspended in the liquid culture. The morbidostat can additionally be used as a chemostat or a turbidostat. The whole system can be built from readily available components within 2–3 weeks by biologists with some electronics experience or engineers familiar with basic microbiology.
