Lighting levels
NOM-025-STPS-2008, lighting conditions in workplace, determine the minimum lighting levels that must affect the work plane, for each type of visual task or work area [19].
NOM-011-STPS-2001, safety and hygiene conditions in workplace where noise is generated determine the maximum permissible limits of exposure of workers to stable, unstable, or impulsive noise during the exercise of their duties [20].
During a maximum permissible exposure time of 8 hours, a noise exposure level of 90 dB is allowed.
Minimum: 77 dB Maximum: 88.8 dB

Thermal environment
NOM-001-STPS-2008, artificial ventilation for worker comfort or due to the requirements of activities in the workplace [21]. NOM-015-STPS-2001, maximum permissible limits of exposure to high thermal conditions [22].
Relative humidity between 20% and 60%. Air temperature of 22°C ± 2°C for times of cold environment and 24.5°C ± 1.5°C for hot times. Maximum allowable temperature in a light duty regime 30°C.
