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.

Chemical composition and chemical properties of hide/skin and chemicals used and their modification during the different tanning processes. Reactions between hide/skin or semi-finished leather and chemical products during the different phases of process and the factors affecting the performance of the reactions and of the process. Monitoring of the chemical indicators of processing and the characteristics of skins/hides/leather.
The quality of hides and skins is defined by organoleptic, microbiological, histological and chemical characteristics (i.e. moisture, structure of the dermis, percentage of fat and collagen). Each type of hide/skin has specific physical and chemical properties that affect the type of tanning operations and the most suitable end use of the leather.

Composition and physico-chemical properties of auxiliary chemicals used in the different tanning processes (tanning agents, fat liquors, pigments, dyes, etc.)
The machinery and equipment used and, in particular, the characteristics regarding functioning and calibration to ensure compliance with quality and product specifications, as well as the operator's safety.
The body of rules, procedures and regulations related to safety, health and welfare of people in their workplace.
Plan the required tanning operations to produce leather. This includes selecting the most suitable type of tanning for each leather good according to final leather market destination.
Analyse, identify and evaluate the possible defects present on raw hides/skins. Defects may be of natural origin, caused by bad practices at the farm, in transport, at the abattoir or generated during the manufacturing process.
Manage systems for the customer-focused organisation of leather production processes. It uses strategy, data, and effective communications to integrate the quality approach into the culture and activities of the company and also to achieve the organisation’s mission and goals.
Solve problems which arise in planning, prioritising, organising, directing/facilitating action and evaluating performance. Use systematic processes of collecting, analysing, and synthesising information to evaluate current practice and generate new understandings about practice.
Lift heavy weights and apply ergonomic lifting techniques to avoid damaging the body.
Regularly inspect and perform all required activities to maintain the equipment in functional order prior or after its use.
Manage the interaction with and impact on the environment by companies. Identify and assess environmental impacts of the production process and related services, and regulate a reduction of the effects on the environment and on people. Organise action plans and monitor any indicators of improvement.
Collect key system performance of leather production at periodic intervals or at the end of some specific phases of the leather process, in order to detect and record the operation of machines and systems and monitor that the process follows the product and production requirements.
