YILDIRIM BEYAZIT UNIVERSITY UE302 Principles of Occupational Health and Safety (OHS)

Student no: 1205024008 Name: Adramane ASSOUMANA Project report: I.

Introduction:

The work is the human activity that allows the production of goods and services. The main aim of this one is to meet the needs of the workers and the others. We encounter several types of work, and each one has its own permanent risks and hazards accordingly. The report below is the enumeration, the classification and the examination of the hazards and risks encountered in building site of Zaloglu insaat company. Particularly while placing a lift in a completed huge building. II.

The OHS hazards and risks at that place

The observation made on the site of construction revealed that the workers are exposed to five major categories of hazards and risks. 1. Material risks: In the construction industry like placing a lift, material risks are the major danger. These ones are: the falls of people or objects, unstable soil and work surfaces, the use of heavy machinery, handling or transport. Strains and sprains are the most common injuries among construction workers. There are also many chronic disabling disorders such as tendonitis, carpal tunnel syndrome and back pain. All these result from poor posture, false movements, excessive strain, violent and repetitive movements. The falls from scaffolding or ladder are also common. 2. Physical risks: Physical risks exist in any construction project. They are related to noise, heat and cold, radiation, vibration and barometric pressure. The construction works are often performed in extreme temperatures, in the wind, rain or snow, in fog or night. Workers can be exposed to radiation, ionizing or not, and extreme pressures. Exposure to Ultraviolet radiation from the sun. Exposure to ionizing radiation is less common, but may exist in control of welds by X or gamma ray, or when using instruments such as flowmeters radioactive isotopes. Lasers are increasingly used and can lead to injury especially in the eyes if the beam is intercepted. 3. Chemical risks: Chemical pollution can be in liquid or semi-liquid (glues or adhesives, tar, etc.), or in powder form which is encountered in our case (such as dry cement). The skin contact with chemicals presented in these forms can be added to the possible inhalation of vapors and lead to the systemic poisoning or contact
