**3. Occupational risks**

 The most significant types of occupational risks for UOG workers are accidents, malfunctions, and exposure to on-site air pollution. Accidents and malfunctions can bring workers in contact with hazardous and toxic materials via inhalation, dermal contact, or ingestion. They can also pose thermal radiation risks due to fires and explosions. Air pollution may be the result of accidents and malfunctions but is also a side effect of typical well-site activities such as oil and gas drilling, production, flaring, venting, storage of liquids and maintenance operations.
