Veterinary Medicine Cornell is a non-profit organization governed by a member Board of Trustees consisting of both privately and publicly appointed trustees. Three trustees are appointed by the Governor of New York: Pollack was inaugurated as Cornell's fourteenth president on August 25, Each defines its own academic programs, operates its own admissions and advising programs, and confers its own degrees.

She did not notice that there was a small amount of residue on the glass. Several hours later, she experienced pain in the palm of her hand and the inside aspect of her thumb.

The result was a serious burn that required skin grafting. She was not aware that this type of burn could result from handling trifluoracetic acid. Trifluoracetic acid can form hydrofluoric acid upon contact with moisture. Hydrofluoric acid can cause deep burns that may not be painful for hours.

Know the hazards of the chemicals involved before handling them. Always assume containers are contaminated and wear appropriate gloves when handling chemical containers.

Keep a hydrofluoric acid burn kit in the laboratory when working with hydrofluoric acid or trifluoracetic acid. She splashed some of the acid onto her latex gloves and it quickly burned a hole through the gloves and caused a small second-degree burn.

She removed her gloves and ran her hand under water for fifteen minutes. Clearly the wrong gloves were used in this case. A better choice of gloves would be those made out of Polyethylene or Butyl Rubber.

When setting up an experiment or handling concentrated chemicals, thoroughly investigate the properties of the materials involved. This is essential to determining the appropriate personal protective equipment.

There has not been a glove made that will protect you against all chemicals. If you are unsure, ask the Safety Office, your supervisor or consult a glove chart. If using disposable gloves and you have splashed something on to them, replace them immediately.

This will minimize exposures through pinholes or degradation. If you are using non-disposable gloves, clean and rinse them thoroughly as appropriate or before switching to another pair.

The worker placed unsealed centrifuge tubes filled with phenol-chloroform into a Styrofoam centrifuge tube shipping container.

The worker immediately flushed the area with a drench hose, but still suffered from second-degree burns to the face, chest and abdomen. Fortunately, the worker was wearing chemical splash goggles and did not receive burns to the eyes.

Appropriate eye and face protection helped to minimize the chemical burn. Wear a closed lab coat when working with hazardous materials. Use a plastic centrifuge rack instead of a Styrofoam packing container, particularly when transporting chemicals.

Failure to Remove Contaminated Clothing Exacerbates Chemical Burns There have been several incidents, usually involving phenol, where laboratory workers spilled a chemical on his or her pants. In all cases, the worker bypassed the safety shower and entered a restroom to remove the pants and rinse the leg.

All resulted in second degree burns that could have been minimized by taking off the contaminated clothing and rinsing immediately using a safety shower or drench hose. Remove contaminated clothing while rinsing. Wear appropriate personal protective equipment, including a closed lab coat when working with hazardous materials.

Do not put contaminated clothing back on.Nothing replenishes an overheated hiker like a wild swimming hole—if only you know where to look. Here, a guide to all the tips and gear you need. Get students talking about lab safety with a do& and don& activity - a fun comic of lab safety mishaps they can discuss in groups.

Find this Pin and more on Labs/Experiments by Hailey Watts. Lab Safety Tips - have students interact with the good bad and ugly of science labs and discuss mishaps and how to correct mistakes. Use these owl journal and folder labels on the front cover of your students' journals and folders.

It will help keep them organized during the school year. How to use: I print these labels off on regular paper (those labels can be so expensive) and attach them with contact paper. Experiments to measure swimming abilities of salmon indicated that the critical velocity was between 8 and 13 feet per second.

Maximum observed swimming speed was feet per second. Preferences of salmonids for water velocities and light conditions revealed marked differences between species. This journal is divided into five parts, the Swimming Science Abstracts, the Carlile Coaches' Forum, the Swimming Science Bulletin, How Champions Do It, and abstracts of research articles covering Training, Physiology, Psychology, Biomechanics, and Hydrodynamics.

The articles presented are drawn from the personal files of the editor. AsianScientist (Mar. 2, ) – The world’s elite swimmers could get even faster, thanks to a new method to measure drag. This research, published in the Journal of Biomechanics, could help modify swim training practices..

A key factor to improve swimming performance is reducing resistance that water exerts on the moving body.
