  the exception of less toxic substances. Such as
  insecticidal soap and round-up.
• Before going into the greenhouse students will
  take the Worker Protection Standards workshop and
  recieve their WPS certification.
• While in the greenhouse or garden area and you
  are exposed to toxic chemicals tell the
  instructor immediatly.
• The three most common ways that you can have
  chemical exposure are
• Oral- by ingesting chemicals
• Dermal- by getting chemicals on your skin
