POISONOUS PLANTS

Recommendations

Employer Recommendations

Employers should protect their workers from poisonous plants by training them about:

  • Their risk of exposure to poisonous plants
  • How to identify poisonous plants
  • How to prevent exposure to poisonous plants
  • What they should do if they are exposed to poisonous plants

Worker Recommendations

Workers can prevent contact with poisonous plants by taking these steps:

  • Wear long sleeves, long pants, boots, and gloves.
    • Wash exposed clothing separately in hot water with detergent.
  • Barrier skin creams, such as a lotion containing bentoquatum, may offer some protection before contact.
    • Barrier creams should be washed off and reapplied twice a day.
  • After use, clean tools with rubbing alcohol (isopropanol or isopropyl alcohol) or soap and lots of water. Urushiol can remain active on the surface of objects for up to 5 years.
    • Wear disposable gloves during this process.
  • Do not burn plants that may be poison ivy, poison oak, or poison sumac.
    • Inhaling smoke from burning plants can cause severe allergic respiratory problems.

Recommendations when Burning Poisonous Plants

Employers should prevent workers from being exposed to burning poisonous plants whenever possible. However, when exposure to burning poisonous plants is unavoidable, employers should provide workers with:

  • A NIOSH-certified half-face piece particulate respirator rated R–95, P–95, or better. This recommendation does NOT apply to wildland firefighters. Firefighters may require a higher level of respiratory protection to protect against possible exposure to combustion products.
  • These respirators should protect against exposure to burning poisonous plants, but will not protect against all possible combustion products in smoke, such as carbon monoxide.
  • Respirators must be worn correctly and consistently throughout the time they are used.
  • For respirators to be effective there must be a tight seal between the user’s face and the respirator.
  • Respirators must be used in the context of a written comprehensive respiratory protection program (see OSHA Respiratory Protection standard 29 CFR 1910.134).
