The work environment whether it is a business office or industrial envi- ronment, needs to be safe, healthy, hygienic, and comfortable. A company is an organization made up of people that invest in the profit objective of selling goods or services. This paper aims to publish the data collected from the environmen- tal thermal comfort and the method of measurements taken in the metalworking industry. The qualitative and quantitative, with structured interviews and comfort variables measurements were taken. The data collected are particularly valuable due to the experimental conditions under which they raised its practical appli- cation is limited to each work environment. The survey carried out on the shop floor allowed randomly to collect measurements on places generating heats or poor ventilation systems. The conclusion that a comfortable thermally controlled industry environment can improve working conditions and ensure the highest level of health protection and in industries’ environmental quality.

In any of these workstations, the enterprise should provide maximum protection of the physical and moral integrity of employees. A company is an organization made up of people that invest with profit objective selling goods or services, also having the purpose to meet the needs of society, generate jobs, and create wealth [1]. It is known that it can cause a high cost for the company’s lack of awareness on the risk of the professions of employees when it stops in minimizing even eliminating those risks bringing costs to the union coffers and own when accidents happen, mutilations even deaths.
