Some regulations, such as those from the Department of Transportation (DOT) or the Environmental Protection Agency (EPA), use strict or specific definitions to identify what counts as a “hazardous chemical.” When discussing workplace safety and OSHA regulations, however, there are broader definitions. For these cases, a “hazardous chemical” is any  Most chemistry laboratories use an excel spreadsheet to maintain an active chemical inventory. If you spill more than one liter of any chemical, or less than one liter of a moderately or highly hazardous chemical, or you are uncomfortable cleaning up the spill, call 911 from a "land line" phone or 919-684-2444 from a cell phone and report the spill to Campus Police. Asbestos. Our general "rule of thumb" for dealing with spills is as follows: For more information check out OESO's Laboratory Safety Manual, Section 3. Look through your home for hazardous chemical products. Asbestos is on the hot list of banned toxic chemicals. 1. And because so many job sites are the source of these materials, a countless number of employees are exposed to extremely hazardous substances every day. Amylase Used to remove starchy soils Generally safe for humans Does not persist in the environment Typical examples include: undergraduate chemistry or biochemistry teaching and demonstration labs, and standard biomedical research labs. Although oxygen itself isn’t necessarily hazardous, the production of oxygen in high concentrations is extremely dangerous. Where it’s found in the workplace: Pipe organs, auto parts, sensing devices, sunblock, ointments, concrete, paint. not only identify chemical hazards, but also to classify these hazards It can also trigger asthma symptoms. Benzene is also used to make plastics, detergents, pesticides, and other chemicals. They will respond to the call and will contact the OESO who will send a spill cleanup team to do the cleanup. Gases include compressed, liquefied, dissolved, refrigerated liquefied, aerosols, and other … Although some types of peroxides can be handled with relative safety, an insidious and treacherous hazard concerning peroxides is their formation from certain classes of compounds after exposure to the air. The purpose of proper labels is multifold: Each research group should have some type of actively updated inventory of the chemicals in their laboratories. These include substances and devices that are regulated by local, state, country, or international law, most often with restrictions of their use by minors such as DEA-controlled substances, prescription drugs, alcohol, tobacco, firearms and explosives. In general, the more dilute the solution, the less hazardous it becomes. In the fourth segment; the notation, W with a line drawn through it is used to warn of a possible violent reaction with water, and the notation, OXY, is used to warn of a strong oxidizing agent which may react explosively with combustible materials.

Explosive and toxic properties of common chemicals are listed in Table II. manufacturers and importers to follow specific criteria when evaluating the hazardous chemicals and when communicating the hazards through labels and safety data sheets (SDSs). There are few greater potential hazards around the laboratory than that of unmarked or improperly labeled chemicals. Liquids with a flash point–the lowest temperature at which fumes above waste ignite–of 60 degrees Celsius or 140 degrees Fahrenheit. A number is used in the first three segments to indicate the degree of hazard with 4 implying severe hazard, 3 for serious hazard, 2 for moderate hazard, 1 for slight hazard, and 0 for minimal hazard. 11635 Northpark Dr, Suite 360 Where it’s found in the workplace: Like pesticides, electronic waste is not a chemical in itself but rather a collection of harmful chemicals found in and around disposed appliances such as televisions, refrigerators, microwaves, computers, and other household appliances.

Where it’s found in the workplace: Agriculture, wood preservatives, glass production, electronics. Class II: moderately hazardous Class III: slightly hazardous The system is based on LD50 determination in rats, thus an oral solid agent with an LD50 at 5 mg or less/kg bodyweight is Class Ia, at 5–50 mg/kg is Class Ib, LD50 at 50–2000 mg/kg is Class II, and at LD50 at the concentration more than 2000 mg/kg is classified as Class III. Therefore, don't store chemicals in alphabetical order--store by category. Oven cleaners and toilet cleaners in particular often contain chemicals in concentrations that require one of these hazard symbols to be used, and whilst it’ll also feature a description of the particular hazard, it’s still useful to know what they mean.
