An organic or inorganic compound that has a pH of less than 7. Acidic materials are corrosive to human tissue. Acute Toxicity Refers to adverse effect suffered as the result of a short, one-time exposure to toxic materials. It occurs within a relatively short period.
Exposure is measured in seconds, minutes, or hours relative to inhalation or skin absorption.
Base An organic or inorganic compound that has a pH of greater than 7. Bases are also referred to as alkalis or caustic materials and are corrosive to human tissue. The temperature at which the vapor pressure of a liquid is equivalent to the surrounding atmospheric pressure, and the liquid rapidly becomes a vapor. Flammable substances possessing low boiling points are considered fire hazards. Caustic Any strongly alkaline material that produces either corrosion or irritation to living tissue.
