A=COM • Wild parsnip is found throughout the U.S. and contains a poison that produces a rash similar to poison oak and ivy. Unlike poison oak and ivy,the active oil will not be present on unbroken leaves. See S3AM-313-ATT6 Wild Parsnip Identification for additional information and photos of wild parsnip. • Several plants in the carrot family contain toxic sap that causes severe dermatitis if it comes into contact with skin that is then exposed to sunlight.The most serious reaction is caused by the giant hogweed (Heracleum mantegazzianum), a plant that is spreading in southern Ontario and is also present in southwestern British Columbia.The plant is enormous, attaining up to 16 feet(5 meters)in height,which it does in one growing season. Contact causes painful blistering that can cause permanent disfigurement. It is to be avoided. Similar but less serious reactions can be caused by meadow parsnip(Pastinaca sativa)and cow parsnip(Heracleum lanatum). Meadow parsnip can be very abundant on disturbed sites. • Nettles, particularly stinging nettle(Urtica dioica)and wood nettle(Laportea canadensis) contain urticating hairs on the leaves and stems that cause sharp pain or itchiness on contact with skin. The irritation is immediate and normally lasts no more than an hour and there are no lasting consequences. • Some plants contain abundant stiff spines that can present a safety hazard, particularly if one is to fall into them. These include the cactus(Opuntia spp.), devils club(Oplopanax horridum), and prickly-ash (Zanthoxylon americanum). 4.8.3 A large number of plants are not harmful to touch but may contain poisonous berries or foliage that could cause serious complications or death if they are ingested. It goes without saying to not eat any berries or plants if you are unsure of their identity. • Remember that in the fall and winter the hazard still exists in the form of stubble and roots. 4.8.4 Personal Protective Equipment(PPE) • Employees conducting clearing, grubbing, or similarly disturbing work activities in areas where poisonous plants exist shall wear long-sleeve clothing or Tyvek®coveralls, and disposable cotton, leather or synthetic gloves. Employees shall not touch exposed skin (neck and face) with potentially contaminated gloves.Tyvek®and gloves worn to protect from exposure to poisonous plants shall be treated as contaminated, removed from the body in a manner that the contamination is not spread, and placed in plastic bags for disposal. • Personal clothing that has been exposed to poisonous plants shall be decontaminated with a poisonous plant cleanser such as Tecnu®or removed in a careful manner, bagged and washed separately from other clothing to remove urushiol. • Work boots will be decontaminated with either soap and water or a cleansing agent such as Tecnu®cleanser. • If foliage is being cleared and includes poisonous plants, exposed skin shall be treated with a dermal barrier cream such as Tecnu®'s Oak`n Ivy Armor or Enviroderm's Ivy Block and either a full-face respirator or a half-face respirator(with goggles)fitted with a P-100(HEPA)dust filter. 4.9 Bird Droppings and Biological Soil Hazards 4.9.1 Work in any area where pigeons or other flying animals(e.g. bats) may nest requires a written statement from the client which states the potential for, and extent of, accumulation of excrement on/in the structure from pigeons or other winged animals. 4.9.2 Substantial accumulations of droppings can pose physical and health risks as slippery surfaces(if wet)and if the material is disturbed and becomes airborne, it can be inhaled or ingested if personal hygiene practices are not implemented. Inhalation of airborne droppings can cause diseases such as histoplasmosis. Exposure to surfaces with bird droppings shall be safeguarded by implementing proper work practices,training employees for awareness and using PPE. See S3AM-313-ATT8 Bird Droppings.
