Relationships with occupations
Characteristics of chemicals used for tanning is an essential knowledge of the following occupations:
Colour sampling operator: Colour sampling operators apply colours and finish mixes according to the defined recipes. They apply pigments, dyes or other finishing mixes.
Air separation plant operator: Air separation plant operators control and maintain the equipment for nitrogen and oxygen extraction from air, ensuring the required operational parameters of pressure, flow and temperature are met. They perform product purity tests and monitor its transfer to storage tanks or to fill cylinders.
Leather wet processing department manager: Leather wet processing department managers plan and organise the work, the staff and equipment of the department involving the washing of the raw hides or skins. They remove unwanted elements, they weigh and prepare it for tanning. They coordinate supply of chemicals and raw materials. They perform elaboration of manufacturing recipes and monitor quality.
Leather production manager: Leather production managers plan all aspects of the leather production process. They ensure the required throughput of the factory in terms of quality and quantity of the leather. They organise the production staff. They monitor and ensure the operation of machinery and equipment. They cooperate with managers of each production department.
Leather laboratory technician: Leather laboratory technicians perform and report chemical analyses and physical tests of leather. They also perform and report chemical analyses of auxiliaries, environmental emissions and discharges. They ensure that the tests are carried out according to appropriate national, international or customer standards.
Colour sampling technician: Colour sampling technicians prepare recipes of colours and dyeing mixes. They ensure consistency in colour while using materials from different sources.
Leather finishing operations manager: Leather finishing operations manager plan and organise the work of the finishing department. They are in charge of chemical supply and equipment management. They also coordinate the staff.
Characteristics of chemicals used for tanning is optional for these occupations. This means knowing this knowledge may be an asset for career advancement if you are in one of these occupations.
Chemical production manager: Chemical production managers are responsible for the technical coordination and control of the chemical production processes. They steer one or more manufacturing units and oversee the implementation of technical and human means, within the framework of objectives of volume, quality and planning. Chemical production managers design and ensure that the production plans and schedules are met. They are responsible for implementation of the processes designed to ensure quality of the manufactured product, good working conditions and environmental practices, and safety of the workplace.
Tanner: Tanners program and use tannery drums. They perform the work according to the work instructions, verify the physical and chemical characteristics of the hide, skin, or leather and of the liquid floats (e.g. pH, temperature, chemicals concentration) during the process. They use the drum for washing the hide or skin, removing the hair (not in the case of hides and skins tanned with the hair or wool on), bating, tanning, retanning, dyeing and milling.
Manufacturing manager: Manufacturing managers plan, oversee and direct the manufacturing process in an organisation. They ensure products and services are efficiently produced within the timeframe and budget given.
Leather finishing operator: Leather finishing operators use machines for finishing leather according to the required specifications by the client for surface characteristics such as colour nuance, quality, pattern and special properties such as waterproofness, antiflame retardance, antifogging of the leather. They arrange the dosage of finishing mixes to apply to the leather and do the routine maintenance of the machinery.
Leather goods production manager: Leather goods production managers perform a wide range of activities and tasks in the field of management, namely, they plan, distribute and coordinate all necessary activities of the different leather goods manufacturing phases envisaging the accomplishment of the quality standards and production and productivity pre-defined goals.
