Specific precautions

Agents causing genetic modification ACGM/HSE Note 4 

Ways in which these principles are applied in practice are illustrated in the following section using common potentially hazardous operations or substances  

Common gases such as oxides of carbon and nitrogen, hydrogen sulphide, and inert gases. Liquids which pose a health hazard due to volatilization, e.g. mercury and degreasing with chlorinated solvent, i.e. dry cleaning with perchloroethylene or metal cleaning with trichloroethylene. 

Liquids posing problems because of the presence of impurities, e.g. mineral oils. 

Machining operations on metals involving cooling by fluids.

Chemical. Where severe chemical contamination is suspected, specific precautions must be followed if OSH A action levels are approached. Such instances rarely occur in LAQ investigations. One possible exception might be a pesticide spill in a confined space. In this case, an appropriate respirator and disposable coveralls may be needed. 

Specific precautions against the inherent hazards of each individual chemical.
