Introduction: Marble and Granite are natural stones that can be shaped into blocks,
slabs or tiles. Their production passes through several stages. The production process
could result in many injuries. Aim of Work: to detect the prevalence of workplace
injuries, their predictors and causes among marble and granite workers. Materials
and Methods: A descriptive comparative cross-sectional study was conducted in
four workshops at Damietta Governorate from June 1, 2016 to May 30, 2017. The
studied groups were composed of an exposed group engaged in the marble and
granite processing and a comparison one who were not engaged in this industry (each
group comprises of 90 workers). They were subjected to an interview questionnaire
asking about sociodemographic characteristics, occupational profile, injury profile
and their anthropometric measurements were taken. Results: All marble and granite
workers experienced one or more injuries in the past year compared to (13.3%) of
the comparison group with highly statistically significant difference (p≤0.001).
They showed high prevalence of superficial wounds, contusion/bruises, tear and
laceration compared to the control group. Unsafe working environment, using
inappropriate instruments, lack of protective equipment and nonadherence to 
donning them were the main causes of workplace injuries. Regarding predictors
for injuries, workers with low income (being in debt) are 18 times prone to injures
than those who can save money. Current smokers are 7.6 times than nonsmokers,
unmarried workers are 6.61 times than married and who live in rural areas are 4.43
times than others who live in urban areas. Conclusion: Providing safe working
environment, donning suitable protective equipment, implementing effective training
programs for all workers especially high-risk ones are crucial preventive measures.
