Gold-workers—those who handle speckled gold, goldsmiths, makers of tapana (refined gold), furnace-blowers, rollers/drawers, dust-washers—shall enter and exit only after being searched (their clothing, hands, and concealed places).
To close loopholes: each role has a different opportunity to conceal gold (on the body, in tools, in dust), so regulation names them explicitly for enforcement.
Workplace access control plus mandatory searches at entry/exit in high-value manufacturing (e.g., bullion refineries, semiconductor fabs).
