Common Plant Irritations
• Irritating plants can cause:– Cuts – Puncture wounds– Itchy, irritated skin– Painful blisters – Rashes– Boils
![Page 3: Prev skinirritationfromplants](https://reader033.vdocuments.mx/reader033/viewer/2022061201/547a5a46b4af9fce158b4a81/html5/thumbnails/3.jpg)
Skin Irritations – Sharp-edged or pointed leaves
• Agave or Yucca have needle-sharp leaves– Can cut or cause skin
abrasion
• Pampas grass looks soft, but actually have razor-sharp edges – Can easily slice/cut skin
![Page 4: Prev skinirritationfromplants](https://reader033.vdocuments.mx/reader033/viewer/2022061201/547a5a46b4af9fce158b4a81/html5/thumbnails/4.jpg)
Skin Irritations - Thorns
• Can cause cuts, abrasions and punctures – Rose Bushes– Bougainvillea– Crown of Thorns– Wild Blackberries/ Raspberries
• Always remove thorns to prevent infection.

Skin Irritations – Spines and Glochids
• Spines – large barbed spines– barrel cactus
• Glochids - very fine, hair-like, barbed thorns– prickly pear– can become embedded
at the slightest touch– hard to see to remove
![Page 6: Prev skinirritationfromplants](https://reader033.vdocuments.mx/reader033/viewer/2022061201/547a5a46b4af9fce158b4a81/html5/thumbnails/6.jpg)

First Aid for Spines, Glochids & Thorns
• Use Tweezers.– Some spines are barbed, causing
intense pain when removed.• Use “Comb Method” of removal
for spines.– Insert teeth of comb between the
barb and skin.– Quickly flip comb (and cactus)
away from body.• Use “Duct Tape Method”– Adhere a piece of duct tape over
the spines and pull it off.

Skin Irritation – Stem and Leaf Hairs
• Stem and leaf hairs – fine hairs found on the
stems and leaves of plants
– harmless-looking but cause skin irritation
• Local plants include:– Borage– Forget-me-nots– Sunflowers
![Page 9: Prev skinirritationfromplants](https://reader033.vdocuments.mx/reader033/viewer/2022061201/547a5a46b4af9fce158b4a81/html5/thumbnails/9.jpg)
Skin Irritation – Barely-There Irritant Fibers
• Tulips– cause skin abrasions– very small, almost invisible
fibers• People who frequently
handle tulips bulbs can get a condition called "tulip fingers“. – Caused the irritating fibers and
a chemical in the bulb.

Skin Irritation – Stinging
• Stinging plants have nettles.
• Touching a nettle can cause a toxic reaction. – doesn’t last long – has no lasting effect
• First aid– Wash with soap & water– Apply antihistamine
cream Nettle leaf close up
![Page 11: Prev skinirritationfromplants](https://reader033.vdocuments.mx/reader033/viewer/2022061201/547a5a46b4af9fce158b4a81/html5/thumbnails/11.jpg)
Common Allergenic Plants
• Cause allergic reactions in some people. • Pollen in these plants can cause hay fever or
asthma.• Include: – Orchids– Chrysanthemums– Dahlias– Hyacinths
![Page 12: Prev skinirritationfromplants](https://reader033.vdocuments.mx/reader033/viewer/2022061201/547a5a46b4af9fce158b4a81/html5/thumbnails/12.jpg)
“The Poison Three”
• Poison Ivy• Poison Oak• Poison Sumac– Relatives of the cashew, mango, and the sumacs.– Over ½ of all the people in the U.S. are sensitive or
allergic.– Cause severe allergic reactions if a person comes in
contact with them.– All three contain the same poison called “Urushiol”.
![Page 13: Prev skinirritationfromplants](https://reader033.vdocuments.mx/reader033/viewer/2022061201/547a5a46b4af9fce158b4a81/html5/thumbnails/13.jpg)
Poison Ivy
• Found in West except for desert regions of California, Nevada and Arizona.
• Found in wooded areas. • Grows as a shrub, ground cover
and tree-climbing vine. • Green leaves that typically form
bundles of three on one purple stem.
• Rarely grows above 5000 ft.
![Page 14: Prev skinirritationfromplants](https://reader033.vdocuments.mx/reader033/viewer/2022061201/547a5a46b4af9fce158b4a81/html5/thumbnails/14.jpg)
Poison Oak
• Usually not found above 4000 feet elevation.
• More common in the western U.S.
• Commonly grows as a shrub from 1 to 6 feet tall
• Leaves are shaped somewhat like oak leaves.
• Leaves usually grow in groups of three on a shared stalk.
![Page 15: Prev skinirritationfromplants](https://reader033.vdocuments.mx/reader033/viewer/2022061201/547a5a46b4af9fce158b4a81/html5/thumbnails/15.jpg)
Poison Sumac
• Shrub or small tree up to 20ft.
• Found all over the U.S.• Found in wet, wooded areas.• Long stem with many leaves
of both green and purplish red colors with a red stem.
• In Fall, colors range from bright yellow to deep purple.
![Page 16: Prev skinirritationfromplants](https://reader033.vdocuments.mx/reader033/viewer/2022061201/547a5a46b4af9fce158b4a81/html5/thumbnails/16.jpg)
Getting Rid of “The Poison Three”
• Wear protective gloves and clothing!• Uproot it in late fall, when it has a minimum of
poison.• NEVER burn it!– Smoke carries the oil, producing a rash over 100
percent of the body– If you inhale the smoke, you can get the rash in
your throat, bronchial tubes, and lungs.
![Page 17: Prev skinirritationfromplants](https://reader033.vdocuments.mx/reader033/viewer/2022061201/547a5a46b4af9fce158b4a81/html5/thumbnails/17.jpg)
“Urushiol” the Poison Connection
• Urushiol is the poisonous oil that causes allergic skin rash on contact.
• Urushiol is found in poison ivy, oak, and sumac. – all parts of the plant, including roots, stems, and
leaves• Doesn’t affect animals.• After 15 minutes of exposure, it bonds to the
skin and can no longer be washed off.
![Page 18: Prev skinirritationfromplants](https://reader033.vdocuments.mx/reader033/viewer/2022061201/547a5a46b4af9fce158b4a81/html5/thumbnails/18.jpg)
Urushiol Exposure
• You can get the oil on your skin by: – Touching the poison oak, ivy or sumac plant.– Touching any clothing, including shoes, that have
come in contact with the plant.– Touching any gardening tools that may have the oil
on it.– Touching any outdoor pets that have gotten the oil
on their hair.– Burning the poison oak plant. The oil from the plant
is carried in the smoke.

The ReactionSymptoms include: – severe itching – reddish colored rash – blistering of the skin
“Contact Dermatitis” shows within 1 – 12 hours.
Severity depends on: – individual sensitivity– size of dose of Urushiol
the person got
![Page 20: Prev skinirritationfromplants](https://reader033.vdocuments.mx/reader033/viewer/2022061201/547a5a46b4af9fce158b4a81/html5/thumbnails/20.jpg)
The Reaction• All parts of the body are
vulnerable.• where the skin is thick,
(i.e. soles of the feet, palms of the hands) = less sensitive
• where the skin is thinner (i.e. around the eyes, underside of arms)
= more sensitive.
![Page 21: Prev skinirritationfromplants](https://reader033.vdocuments.mx/reader033/viewer/2022061201/547a5a46b4af9fce158b4a81/html5/thumbnails/21.jpg)
Immediately wash irritated area: • Use non- oil containing soap.• Clean area with rubbing
alcohol.• After the rash has developed,
treatment is based on relieving symptoms.
• Visit a doctor if you get a fever or have trouble breathing.
Treatment
![Page 22: Prev skinirritationfromplants](https://reader033.vdocuments.mx/reader033/viewer/2022061201/547a5a46b4af9fce158b4a81/html5/thumbnails/22.jpg)
Relieving the Symptoms What You Can Do
• Use cool compresses.– Cold water or whole milk
• Use over-the-counter itch creams.– Calamine Lotion– Aloe Vera gel– Oatmeal baths/soaks
• Take antihistamines.– Benedryl or similar
• Wear loose, cotton clothing.• See a doctor if fever, infection or
symptoms persist!

Emergency Treatment
Accidental poisoning can occur:• accidental ingestion• inhaling smoke from poisonous plants
– trouble breathing– high fever– irritation and swelling in the throat– can be deadly!
![Page 24: Prev skinirritationfromplants](https://reader033.vdocuments.mx/reader033/viewer/2022061201/547a5a46b4af9fce158b4a81/html5/thumbnails/24.jpg)
Accident / Exposure Prevention• Communicate hazards.• Recognize and avoid hazardous plants.• Reassign employees who are extremely sensitive
to toxic plants, to less exposed duties.• Wash tools, clothes, and other items came in
contact with toxic plants.• Use commercial products that can help keep the
urushiol oil from getting into your skin. – “Ivy Block” is the only FDA approved product.– Forms a clay-like coating on the skin.
![Page 25: Prev skinirritationfromplants](https://reader033.vdocuments.mx/reader033/viewer/2022061201/547a5a46b4af9fce158b4a81/html5/thumbnails/25.jpg)
Personal Protective Equipment (PPE)
• Wear protective clothing.– Long pants– Long sleeves– Boots– Gloves
• Make sure all clothing overlaps to prevent exposure.
• Use safety glasses or face shield when cutting.

Fatalities
• There were no OSHA reported fatalities related to any of these plants for the years 1990-2009. – Source: OSHA Fatality Data-1990-2009

True or False? Review1. Wash your shoes separately in hot water after
handling toxic plants. 2. Burning plants can release harmful toxins into the air. 3. After handling plants, always wash your hands and
other exposed skin before eating, drinking, smoking, or going to the bathroom.
4. Don’t bother removing thorns from skin, they will eventually fall out on their own.
5. Wear short-sleeved shirts so you can spot skin reactions easily.
