11? Follow the simple 7:\n\n1- Gloves, coat and goggles at all times\n2- closed toed shoes or safety boots\n3- don't spill, handle with care\n4- store chemicals in compatible chemical cupboards following OSHA standards\n5- know cleanup procedures for all chemicals in your lab\n6- know your emergency procedures (emergency exits and evacuation, fire hoses and extinguisher locations, raising alarms, emergency phone locations and numbers)\n7- keep msds sheets of all chemicals in your lab on file and accessible to everyone.\n\nAll personell should know all these.

If this is a plant, there will be thousands of chemicals present.  Of course water and celluose will be #1 and #2.

take a large sheet of aluminum foil, spray oven cleaner all over it, fold it up and put it in a 2 liter soda bottle (plastic is safer), tighten the lid and throw it, or stand back. - do this outside.

It would depend on what the nature is of the unwanted impurities. One could use chemical separation or distillation.  Distillation would be the easiest.

First make a chemical equation, balance it, and find a mole ratio.  Use that ratio and the above information to solve the problem.

http://ohioline.osu.edu/~agsafety/ash/programs/osha_labs.html\n\nYes, there is.\n\nCompliance with the Laboratory Safety Standard was initiated for the College of Food, Agricultural and Environmental Sciences Columbus campus in June, 1998. This standard applies to all departments that deal with wet chemistry on a laboratory scale i.e. operations easily manipulated by one person, large number of chemicals, small quantities of material, multiple procedures used, not part of a production process, etc. Compliance is similar to that for the Hazard Communication Standard with some additional requirements. The following outline should assist you in complying with this regulation. Please call the college safety office if you have any questions or require any assistance. \n\nRequirements and What to Do \n\nWritten Chemical Hygiene Plan \nObtain generic Chemical Hygiene Plan from OEHS at http ://www.ehs.ohio-state.edu/index.asp?PAGE=ehs.chp, or the college health and safety speacialist, follow instructions, add sections and fill blanks, modify if necessary. Locate your written Chemical Hygiene Plan in a place accessible to employees. \n\nChemical Information \nInventory chemicals and obtain MSDS's for those with hazard ratings of 4. Locate MSDS's with Chemical Hygiene Plan. Post inventory on laboratory door. Provide access to and identify sources of chemical information.Retain labels on chemicals received. You may search for MSDS's at http://www.ehs.ohio-state. edu/. \n\nTraining\n\nIdentify and list employees required to have training. Send laboratory supervisors and employees to OEHS or the college health and safety speacialist for generic lab standard training.Train employees on special procedures for handling laboratory chemicals.Document training.

useful substances enter and waste products exit of course.\nuseful substances include glucose, oxygen, amino acids, etc.\nwaste products would be carbon dioxide, urea, etc.

One that will ideally:\n1) dissolve the component that you wish to collect but not the others. Then you can do a filtration, collect the filtrate and evaporate off the solvent to get back the component that you want.\nOR\n2) dissolve all those that you don't wish to collect but not the component that you want. Then you can do a filtration and collect the component that you want as the residue.\n\nHope this helps :)

A simple answer is avoid polluting the air, if go into details avoid releasing gases like CO, CO2, HFC contents (scuh as halon, freon) in to air, avoid cutting trees, the most important is to reduce pollution did u heard about Kyoto protocol in that almost all the countries signed a pact to reduce industrial emissions but lated USA quit from it saying that it affects their industry.

Every chemical workers are exposed to in the workplace are supposed to have a hazard label with information including flammability, health hazards and safety precautions as well as exposure limits and first aid instructions in case of accidental exposure. Since there are thousands of such chemicals, I suggest you read the labels of the chemicals you could come in contact with at your work and learn the precautions.

The easiest way to find out the answer to that question is to look up the MSDS.  It gives all the information you need about it's toxicity, reactivity, etc.  A lot of chemical supply companies have MSDS on their websites, and I think there might be a government website that has MSDS accessible online, but I'm not sure.

To minimize the risks while working with sulfuric acid, appropriate precautions should be taken. For example, water should never be added to the concentrated acid, as the water could boil; rather, acid should be added to water.\n \nSee link below and scroll down to “Safety”.

If you are working in a chemical lab, you should have gotten this answer during your safety training.  However, in the case of most strong acids (HCl, HBr, HI, H2SO4, etc.) you should flush with lots of water.  If irritation persists, you should seek medical attention promptly bring with you the MSDS for the chemical you spill on yourself.  If you spilled HF, you are in deep trouble.  However, I doubt you could have gotten access to HF without knowing the appropriate precautions to take.\n\nMedically, some acids are used in the removal of warts (among them is trichloroacetic acid).  The alternative there is freezing them off with liquid nitrogen.

Material Safety Data Sheets are required by local, city, county, state and the federal government so that employees can learn if they are using dangerous materials.\n\nThe company must tell the employees if they are using dangerous chemicals or products.\n\nAny contractor working at your home also has to provide you with this information.\n\nAnd if you are working with chemicals at home, it is required that the company that sells you the product have the information available. For instance if you buy a wallpaper remover chemical at a paint store, you can ask for the safety sheet when you buy it.\n\nIf you have a business in your home, you may be required to keep safety sheets on file, even if you are the only employee.\n\nIf you are an artist working with dangerous chemicals, you may need a permit from a local or other government agency, and you will be required to show these documents.\n\nBest wishes.
