Occupational health problems may not cause fatal injuries as in the case of general physical injuries on a construction site. Yet, there are far more occupational health injuries than serious physical injuries. Although some problems may be fairly mild, occupational health hazards have a long latency period and what may be a small problem in the short term could prove fatal in the longer term, particularly something like asbestos inhalation. Lung cancer can develop as a result of exposure to such a toxic substance. This article seeks to expose the extent of occupational health problems and suggests how improvements can be made to reduce such occurrences. These include the preparation of health and safety plans for construction work and minimising workplace stress.
