Handling of Hazardous Substances

The handling of hazardous chemicals, infectious, toxic or radioactive substances, calls for a high degree of responsibility on the part of everyone involved, to ensure personal and environmental protection. The relevant regulations must be scrupulously observed including laboratory, professional association, environmental, radiation, waste disposal and generally accepted technical standards and guidelines (e.g., DIN or ISO).

Important information on safety

  • Before use, laboratory instruments must be examined by the user for suitability and functionality. 
  • Before use, laboratory instruments should be examined for potential damage, especially instruments subjected to pressure or vacuum (e.g., desiccators, filter flasks, etc.). 
  • The hazards of working with defective labware should never be under-estimated (e.g., cuts, burns, risk of infection). If a professional repair is not practical, properly dispose of such items.
  • Instruments to be repaired must be cleansed of all residues and be sterilised, as necessary. Radioactively contaminated items must be decontaminated as prescribed by the radiation protection authorities. Volumetric glass instruments (e.g., volumetric flasks, graduated cylinders, etc.) should not be repaired when damaged. Exposure to heat may result in residual stress within the glass (greatly increasing the probability of breakage), or an uncontrolled cooling process may lead to permanent volume alterations. 
  • Cutting down damaged graduated cylinders shortens the distance between the upper graduation mark and the spout, as defined by DIN, resulting in an increased danger of chemicals being spilled. 
  • Waste must be disposed of according to local laws and regulations. This applies also to disposable articles. It must not pose a hazard to human beings or the environment. 
  • Please properly dispose of laboratory glassware, being sure to remove any potential contaminants.
