Can you please check the blue parts? Thank you.

The production of the oil industry is carried out continuously, throughout 24-hour-work process, due to which operators work in shifts of eight or twelve hours. In refineries, operators spend more than half of their working hours outside, going around the palnt, controling and coordinating various parameters and equipment/apparatus. Obligatory chek-ups of the plant are determined/prescribed by the so called working procedures and are carried out in all weather conditions, at every time of day or night.
