Weeks, Bill, Fill-In Producer has reference to this Academic Journal, PHwiki organized this Journal Chemistry Laboratory Safety Rules Sharps Safety A high degree of precaution must always be taken with any sharp items used in the laboratory, including needles in addition to syringes, glass slides in addition to cover slips, Pasteur pipettes, capillary tubes, as well as broken glass, in addition to scalpels, blades, in addition to knives. Sharps must be disposed of in an approved sharps container. Sharps containers may never be placed in the normal waste stream or used as long as any purpose other than sharps disposal. Sharps containers have to be: Puncture Resistant Clearly marked Within easy reach of the work station Filled to no more than 3/4 capacity Sealed (i.e. capped or taped) prior to transport Sharps Safety CHEMICALLY CONTAMINATED SHARPS: Sharps contaminated with hazardous materials must be placed in a puncture proof container in addition to sealed with a screw-on cap. The container must be labeled as hazardous waste, with the associated chemicals identified. Contact Phil Dennicort in the Chemical Stock Room (x 2338) as long as disposal. In case you poke yourself with sharps: Squeeze out blood; If necessary, seek medical attention immediately (know what was the contaminants of the sharps/what was in the needle).

Safety Topic – Chemical Hood General purpose: prevent exposure to toxic, irritating, or noxious chemical vapors in addition to gases. A face velocity of 100 feet per minute (fpm) provides efficient vapor capture while reducing hood turbulence. Baffles – keep the airflow uni as long as m across the hood opening, thus eliminating dead spots in addition to optimizing capture efficiency. Sash -Airflow across the hood can be adjusted by sash height to the point where capture of contaminants is maximized. Airfoil – Preventing the creation of turbulent eddies that can carry vapors out of the hood. The space below the bottom airfoil provides source of room air as long as the hood to exhaust when the sash is fully closed. Exhaust plenum – An important engineering feature, the exhaust plenum helps to distribute airflow evenly across the hood face. Face – The imaginary plane running between the bottom of the sash to the work surface. Hood face velocity is measured across this plane. Common Chemical Hood Misconception Myth – When working with highly hazardous materials, the higher the face velocity the better While it is important to have a face velocity between 100 in addition to 125 fpm, velocities higher than this are actually harmful. When face velocity exceeds 125 fpm eddy currents are created which allow contaminants to be drawn out of the hood, increasing worker exposures. Myth – A chemical hood can be used as long as storage of volatile, flammable, or odiferous materials when an appropriate storage cabinet is not available. Hoods are not designed as long as permanent chemical storage. Each item placed on the work surface interferes with the directional airflow, causing turbulence in addition to eddy currents that allow contaminants to be drawn out of the hood. Myth – The airfoil on the front of a hood is of minor importance. It can safely be removed if it interferes with my experimental apparatus. Airfoils are critical to efficient operation of a chemical hood. With the sash open an airfoil smoothes flow over the hood edges. Without an airfoil eddy currents as long as m, causing contaminates to be drawn out of the hood. With the sash closed, the opening beneath the bottom airfoil provides as long as a source of exhaust air. Safe Hood Operating Procedure Constant volume hood – the volume of air exhausted is constant, regardless of sash height. Proper positioning of the sash is vital to maintaining the optimum face velocity (100 or 125 fpm). Too high: lowers face velocity, allowing contaminants to escape from the hood Too low: results in very high face velocity, excessive turbulence in addition to loss of containment Confirm that the hood is operational: switch ‘on’, airflow gauge or ‘flow check ribbon’ hood test data in addition to optimum sash height – yellow label affixed to the hood face Maintain operations at least 6″ inside the hood face. Lower sash to optimum height: maximized airflow without turbulence (17” in accordance to the rules in Colgate University Keep head out of hood Keep hood storage to an absolute minimum Minimize foot traffic around the chemical hood Use extreme caution with ignition Replace hood components prior to use

Protect Your Eyes Appropriate eye protection must be worn at all times! Wear appropriate protective clothing Your clothing should cover your legs to the knees – shorts are not appropriate as long as the laboratory Lab aprons can be used to protect good clothing Loose clothing should not be worn because it may dip into chemicals or fall into a flame in addition to catch fire Wear shoes that cover your feet. S in addition to als in addition to open-toed shoes do not protect your feet from broken glass that is frequently found in the lab Also, leather shoes protect your feet from chemical spills – canvas shoes do not.

Do not apply cosmetics, eat, or drink in the lab. These activities are ways by which you can accidentally ingest harmful chemicals Do not taste any chemical! Pour from large containers to smaller ones.

Always ADD ACID to water acid water “Do not spit into acid!” – a good phrase to remember this rule. Hold your h in addition to over the label while pouring. Work with volatile chemicals under a fume hood.

Check glassware as long as stars or cracks. Heat test tubes at an angle, directing the opening oppositely to you in addition to other people in the laboratory. H in addition to le hot glassware with gloves or beaker tongs.

First light the match THEN Turn on the gas! Do not smell any chemicals directly! If absoluteley necessary to smell, use your h in addition to to fan the vapor to your nose. Do not pipet solutions by mouth! Use a rubber suction bulb or other device to fill a pipet.

Wash your h in addition to s with soap in addition to water be as long as e leaving. This rule applies even if you have been wearing gloves! Know the hazards of the materials being used. Read in addition to reread labels carefully to make sure that you are using the right chemical. Know how to interpret data from a MSDS. Tie Back Loose Hair Dangling hair can fall into the Bunsen burner in addition to catch fire or can fall into a chemical solution P.S. Burning hair REALLY STINKS!

Never remove chemicals from the laboratory This guy put chemicals in his locker! Don’t work alone in the lab In case of a problem, you may need another person to prevent injury or even save your life! Remember that the lab is a place as long as serious work! Careless behavior may endanger yourself in addition to others in addition to will not be tolerated!

Report any accidents or unsafe conditions immediately!
