Minerals And Mining (Health, Safety And Technical Regulations, 2012) (L.I. 2182)
Regulation 239
(1) The manager of a gold processing plant shall in relation to that plant appoint a competent person to conduct regular HCN gas surveys in each area in a metallurgical treatment facility to identify high risk exposure areas.
(2) The measurements connected to the survey shall be performed during windless days.
(3) The manager of a gold processing plant shall in relation to that plant ensure that areas where HCN gas concentrations are likely to exceed 10 ppm are identified by means of proper notices stating the risk and monitored by means of fixed continuous detection instruments with a data logging facility.
(4) The monitoring system shall contain an audible alarm at the site, and specific procedures shall govern work practices and evacuation of personnel from the affected areas.
(5) The manager of a gold processing plant shall in relation to that plant ensure that
(a) measurements made for the detection and warning of the presence of cyanide gases and cyanide reaction products are performed continuously during periods of maintenance carried out on closed vessels, sumps, confined spaces and poorly ventilated areas;
(b) cyanide bearing effluent in and around the plant is identified, sampled and analysed for free, titratable and WAD cyanide and proper actions are taken to return the effluent to the process or to effectively detoxify the effluent;
(c) a management system is implemented to monitor cyanide levels in plant slurry and water reticulation systems in order to prevent circulation of possible high cyanide containing solutions which may arise from ineffective spillage detection systems; and
(d) measurement and monitoring equipment are calibrated as recommended by the supplier and a management system established for the recording of all the measurements made.
