Main content

Allways read the safety data sheet before start working with chemicals or biological factors.

  • It is prohibited to bring or consume food or drink of any kind in the laboratory. Freezers and refrigerators in the laboratories must not be used for the storage of food items. The same applies to the use of laboratory equipment – for example, beakers – for food and drink, even if the equipment is new and has not been used for chemicals.
  • Generally speaking, protective goggles must be worn at all times. The wearing of contact lenses should be avoided where possible.
  • New cotton laboratory coats. Synthetic fibre materials can produce sparks from static electricity and, in the case of undesirable events, can lead to unpleasant burns as synthetic fibres melt.
  • Wear shoes that are “sealed” over the toes to avoid injuries in the event of a spillage of chemicals.
  • Protective gloves must be worn when using corrosive, toxic, irritating or allergenic compounds, as well as for chemicals that are hazardous on contact with skin.
  • Laboratories must always be kept clean and tidy.
  • Never taste chemicals or solutions even if you think you are sure that they are harmless.
  • Never use your mouth for pipetting. Use a rubber balloon, burette, pipette pump, electric pipetting device or other equipment.
  • Spillages on workbenches and floors must be wiped up immediately, irrespective of whether they are from chemicals or water.
  • Wash hands thoroughly after contact with chemicals. Use soap and water, not organic solvents.
  • Working with certain kinds of chemicals requires exposure registration.
