An industrial safety review involves examining enterprises with a dangerous production process: coal mines, chemical plants, oil refineries, gas supply stations, industries using explosives, and other objects. Surveyed industries are called objects of expertise.
An industrial safety review is necessary to determine how technological standards are being followed. It helps to find out how safe the production process is for people and the environment. The examination is carried out by specialists of Rostekhnadzor, who, based on the results of their work, issue an
expert opinion on the safety of production. The work of experts is paid for by the audited company, since it is itself interested in having all the relevant documentation, without which the company cannot function.
The survey begins with a study of the submitted papers. All equipment used at this facility must have certificates of conformity. Next, the fire system is checked (are there special sensors, an evacuation scheme for workers). If this is a chemical production, then there must necessarily be protective equipment and an emergency response plan is developed.

An industrial safety review provides for the examination of various industrial structures: bridges, highways, road junctions, heat and water supply systems, power supply and communication facilities, oil and gas pipelines. All these facilities are included in the list of strategic sites. Examination of structures is carried out in order to determine how safe they are during operation, how correctly and economically justified they were built. The study begins with a study of design and construction documentation, then comes the work of experts who give their opinion on technical and environmental reliability. A laboratory test of materials is done, the strength of the supporting structures is checked.

Examination of the quality of services is another kind of expert work. I must say that this is a rather problematic type of activity. Because it is based on the subjective opinion of consumers of services and depends on their attitude to the issue, mood, well-being and many other rapidly changing factors. The most reliable way to conduct such an analysis is to survey consumers and calculate the number of critical cases. Interviewed as many people as possible. People are asked to rate the service according to a simple criterion - like / dislike. Then draw the appropriate conclusions. This method is widely used for marketing research.
An industrial safety review is an effective method of preventing technological accidents, the consequence of which is a large number of human casualties and multimillion-dollar losses.
