Ranks in the profession
There are 7 categories of this profession, each of which implies its own level of complexity of operations that a laboratory assistant can perform. The first two grades, for example, allow him to take on the simplest homogeneous analyzes without first separating the components involved. The third and fourth categories of chemical analysis laboratory assistants increase the complexity of procedures by expanding the range of substances and characteristics under study. For example, those skilled in the art can determine properties such as solubility, viscosity, and specific gravity. The next step allows laboratory technicians to perform complex analyzes that involve the same metal alloys based on nickel, cobalt and titanium. The difference between laboratory assistants of the 7th category is the increase in the technological level of the methods used, as well as the use of specialized equipment.
Labor protection rules
Apart from general requirements, which are aimed at ensuring the safety of employees of a chemical analysis laboratory assistant, and involves compliance with a number of special rules.
First of all, special attention is paid to working with harmful elements and substances. Such analyzes can only be performed in rooms where a forced ventilation system is provided. At the same time, a specific airflow suction rate is also set: not lower than 0.5 m / s. Also, a chemical analysis laboratory assistant who works at the enterprise should receive personal protective equipment free of charge. For example, a bathrobe and boots are issued for a year, an apron is calculated for six months, and gloves for a month.
What is the salary?
Laboratory assistants cannot boast of generous pay. By the way, novice employees receive 10-15 thousand rubles. As their work experience and, accordingly, their rank increase, they can already claim 20-30 thousand rubles. However, more high levels salaries are rare and occur only in major cities. Most promising direction for this profession can be considered the petrochemical industry. In such industries, there is a rather intensive improvement in the qualifications of chemical analysis laboratory assistants from the 1st or 2nd up to the 4th category. In this case, the position of the head of the laboratory can be considered as the highest point of a career.
Conclusion
The profession of a laboratory assistant in last years regains its once-lost relevance and prestige. Of course, in itself this place is not so attractive when compared with the work of specialists in different fields. However, a chemical analysis laboratory assistant, whose duties at the first stages are within the power of a wide range of graduates, has good opportunities for gaining experience. It is precisely as the initial stage of career formation that this profession is considered not only by scientists, but also by technologists, teachers and specialists in related fields. Of course, there are serious disadvantages in such work, due to close contact with chemicals. It is enough to name the risk of burns, allergic reactions and poisoning.
