"Hazards
As an
organic solvent, its vapour can irritate the skin and eyes, damage the
lungs and respiratory system, as well as the
central nervous system when inhaled, and cause
renal failure when ingested, among other things. Being combustible, it also poses a fire hazard. Because turpentine can cause spasms of the airways particularly in people with asthma and whooping cough, it can contribute to a worsening of breathing issues in persons with these diseases if inhaled.
People can be exposed to turpentine in the workplace by breathing it in, skin absorption, swallowing it, and eye contact. The
Occupational Safety and Health Administration (OSHA) has set the legal limit (
permissible exposure limit) for turpentine exposure in the workplace as 100 ppm (560 mg/m3) over an 8-hour workday. The
National Institute for Occupational Safety and Health (NIOSH) has set a
recommended exposure limit (REL) of 100 ppm (560 mg/m3) over an 8-hour workday. At levels of 800 ppm, turpentine is
immediately dangerous to life and health."
