World Leader in PlatinumAnnual Facility VisitSAFETYWe are making progress :A reduction in fatality rate (FR) and Lost TimeInjury Frequency RateFR = 0.03 (Last year 0.04)LTIFR = 2.95 (3.75) Target 2002 =1.4Rates compare favourably to platinum andgold industry.Behavioural based safety / continuousbusiness Improvement.Mechanisation (quantum improvement)
