Cyclohexane

Petroleum refining and gasoline; manufacture of nylon intermediates; emissions from solvent-based paints, glues, and degreasers [1][3].

Breathing vapors at work, while fueling vehicles, or when using solvent-based products indoors; skin contact with liquid; less often through drinking water near spills [1][2].

Short-term exposure can cause dizziness, headache, nausea, and poor coordination; very high levels can lead to unconsciousness. Repeated exposure can dry/irritate skin and affect the nervous system. Not known to cause cancer in humans [1][2][3].

Refinery and chemical workers; auto repair, painting, printing, or adhesive users; people in poorly ventilated spaces; children and pregnant people may be more vulnerable to solvent effects [1][2].

Use products outdoors or with good ventilation, choose low-VOC options, keep containers closed, avoid breathing fuel vapors, and use workplace protections (gloves/respirators) as required [1][2].
