Color safety measures

Attitudes to TVOC measurements vary widely. Some like the concept of a TVOC parameter because it is simple to understand as a pass/fail criteria. However, it is not a reliable indicator of product safety or acceptability unless it is specifically applied to comparisons of very similar products, for example, different batches of the same material or products within a range that are essentially the same, but may have a different color or patterned finish. 

The FDA also instituted a premarketing approval process that requires color producers to ensure, before marketing, that products are safe and properly labeled. Should safety questions arise later, colors can be reexamined. The 1960 measures put color additives already on the market into a provisional listing. This allowed continued use of the colors pending the FDA s conclusions on safety. 

In addition to reaction chambers and delivery systems, a number of supervising and sensor systems are of utmost importance for control and safety reasons. Sensors in automated workstations include measurement of temperature (thermocouple, thermistor, semiconductor), pressure, liquid flow and gas or liquid level. To monitor the presence or absence of vessels or devices, systems like capacitance, inductivity, ultrasonic monitors, magnetic sensors or optical sensors (reflective, beam interruption, color) can be integrated in automated workstations. 

A detailed description of the biochemistry, chemistry and biology of natural colour pigments can be found in the book Natural Food Colorants. The book also covers the role of biotechnology in the production of colorants as well as safety aspects. Another book with the same title, Natural Food Colorants, assembles the manuscripts from a two-day Basic Symposium on Natural Colorants held in Chicago in July 1999. The book covers natural colorant chemistry, preparation, formulation, application and measurement as well as safety, regulatory and health considerations. ... 

ABSTRACT Individuals spend most of their time in work environments and because of this reason their workplaces should be provided with optimal work conditions in order to increase performance and avoid work accidents. Thermal discomfort is one of the causes of work dissatisfaction which lead to individuals behavior changes as well as works accidents. This paper aims to study a manufacturing industry inner space affected by heat thermal environments in order to identify the most critical areas regarding two thermal indexes, EsConTer and THI, in which their interpretations valorize workers thermal sensation. From the color maps developed to facilitate indexes analysis the most critical areas of the space in study were easily identified as well as the most critical workstations near those areas. The health and safety department of the industry in study valorized the results in order to develop measures that may improve the occupational health of the occupants due to the approximation of the indexes results to workers thermal sensation.
