BasicsExperimental works should be carried out carefully and cautiouslyOperating instructions have to be createdBefore starting the experimental works a risk assessment of the workplace and the workplace conditions has to be madeExperimental workplaces with higher security requirements have to be checked by an occupa-tional health and safety practitioner before the works start (Abt. 4.2 - Arbeits- und Umweltschutz)

Adopt specific measures:- match with the [S]TOP-Principle

- technical solutions are the most effective

Implement concrete measures:- process control (on schedule?)

- efficiency control (danger eliminated?)- preservation control (sustainable development?)- up-dating of the risk assessment

Basics

When you are working with chemicals hold ready operational instructions and safety data sheetsThere are special regulations for works with hydrofluoric acid and sulfochromic acid (get informations from Dep. 4.2) The disposal of the chemical waste must be conducted according to the standards of the University of BonnBy the way…. Hydrofluoric Acid

Resorptive poison impact leads to death

Inhalation of a small doses leads to broncical catarrh

Inhalation of a large amount leads to heavy corrosive injuries like lungedema

Massive Inhalation of HF-gas leads to aquick death

Symptoms of intoxication can occur even weeks after the intoxication but normally in a couple of days

Hydrofluorig acid and hydrofluoric solution should contaminate thewaste water but has to be disposed after the regulations of the University of Bonn
