Obiettivo (i) To assess the effectiveness of existing methods in assessing the risk from exposure to chrome and other acid mists. (ii) To investigate and develop reliable methods for monitoring exposure to chrome and other acid mists in the Steel Industry. (iii) To survey personal exposures and ambient levels in work areas around process lines using acids e.g. Chromic, Sulphuric, Hydrochloric, Hydrofluoric and Hydrofluoroboric acid. (iv) To develop a method for testing the effectiveness of containment measures in order that any risk from these processes may be kept to a minimum thereby safeguarding the health of operators. (v) To provide occupational exposure data for future epidemiological surveys.(i) Recent experience in British Steel has cast doubt on the validity of data obtained in studies of acid mist using the form of sampling currently recommended by the UK Health and Safety Executive for the measuring of airborne particulate matter. In addition, epidemiological work published in the last decade has indicated the possible link between exposure to acid mist and laryngeal cancer. Knowledge of the deposition characteristics of particulate matter in the respiratory airways suggests that the size - characteristics of emission of this type are extremely important in the aetiology of associated occupational disease. It is therefore essential that the size collection efficiency of the currently recommended sampling technique is defined with regard to the mists being sampled. (ii) The acid mist sampling techniques used by other researchers will be studied to establish whether their sampling methods are more appropriate to this situation. (iii) A semi-quantitative sampling technique that has recently been evaluated in British Steel, will be investigated further to establish whether it has the potential for being developed into a method for routine sampling. (iv) Using sampled techniques appropriate for the acid mist droplet size range identified as causing biological concern, environmental studies will be carried out to quantify emissions produced by the various processes involving acids in the steel industry e.g. pickling, passivating, plating and pre-treatment. (v) Studies of occupational exposures will be undertaken using the sampling methods developed. These data will be used for establishing where, how and what type of control and personal protective measures should be applied and will also provide background information for future epidemiological studies. (vi) Strategies will be developed for monitoring the effectiveness of containment measures.
