OTHER: Referral to a physician is recommended if there is any question about the seriousness of the injury/exposure. CONTROL MEASURES AND PERSONAL PROTECTIVE EQUIPMENT VENTILATION: General (i.e., natural or mechanically induced fresh air movements that maintain vapor concentrations below recommended exposure limits). EYE PROTECTION: Not required, however, safety glasses should be worn in most industrial settings SKIN PROTECTION: Cloth may be suitable; impervious (neoprene or rubber) gloves are recommended. RESPIRATORY PROTECTION: Not normally required. Where ventilation is inadequate to control vapors, use a NIOSH-approved respirator with organic vapor cartridges. Never enter a confined space without an appropriate air supplied respirator. PRECAUTIONS FOR SAFE HANDLING AND USE HANDLING AND STORING PRECAUTIONS: Store in a cool, dry area. Keep from freezing. Store between 40° and 100° F. For industrial use only. Keep out of reach of children. Use with adequate ventilation. Do not get into the eyes. Avoid prolonged or repeated contact with the skin.
