Iron and steel industry is a heavy industry and is characterized by high accidents rates than those in most industries owing to the inherent risks in the entire rough processes. The aim of the study is to demonstrate the accident trends in Alexandria National Iron and Steel Company [ANSDK] from 1988 to 1999, to identify the applied accident prevention control system at the company, and to illustrate its effectiveness. Accidents [injuries] have been investigated and analyzed in the study period. Results revealed that the age group of 25-29 years had reported the highest record of injury in the first 6 years [1988-1993] and trans located to the age group of 30-40 years in the next 6 years [1994-1999]. The main reasons of injury are lack of attention and unsafe working methods [28.4% and 16.4%, respectively]. The main cause of injury is accidental fall and caught up between things [25% and 20.5%, respectively]. Upper and lower extremities were the most affected organs. All the aforementioned categorized results were highly significant [p=0.000001]. The accident prevention control system is summarized as; i- intensive patrolling and inspection of work places, ii- continuous review of safety standards and procedures, iii- enforcement of usage of available personal protective equipment, iv- continuous safety training and education for all employees, and v- applying safety commendation system. The continuous follow up of execution of the aforementioned procedures has led to the dramatic decrease of accident incidence from 204 in 1988 to 24 in 1996. Consequently, frequency rates decreased from 49.6 to 4.6 and severity rates from 1.163 to 0.226 in the same period. Best prediction equations for accident parameters and rates were derived. The actual accident parameters and rates were much lower than predicted ones from 2000 to 2004. The present study emphasized the integrity and success of the accident prevention control system and it is highly recommended to be applied in heavy industrial sector.
