A=COM • If stung by a wasp, bee or hornet, notify a co-worker or someone who can help should you have an allergic reaction. Stay calm and treat the area with ice or cold water. Follow AECOM incident reporting guidelines to report the sting within 4 hours and notify the Manager or Supervisor immediately. Seek medical attention if you have any reactions to the sting such as developing a rash, excessive swelling or pain at the site of the bite or sting, or any swelling or numbness beyond the site of the bite or sting. 4.7.9 Fire Ants • The fire ant(southern and western U.S.)and the European fire ant(northeastern U.S. and eastern Canada)is often very abundant where it is established. It is very aggressive and commonly climbs up clothing and stings unprovoked when it comes into contact with skin. Painful irritations will persist for an hour or more. 4.7.10 Personal Protective Equipment(PPE) • Chemically-treated field clothing,full-length clothing, or Tyvek®coveralls. • Gloves shall also be worn consistent with the recommendations of the site-specific SWP and/or THA to minimize hand exposure. • Where ticks, chiggers, and spiders are presumed to exist, the Tyvek®or chemically treated clothing will be taped to the work boots. • See S3AM-313-ATT2 Ticks for configuration of clothing for protection against ticks and insects. • Application of insect repellent to clothing and/or exposed skin. Oil of lemon eucalyptus, DEET, and Permethrin have been recommended by the CDC for effective protection against mosquitoes that may carry the West Nile virus and related diseases. • Note that DEET will reduce the effectiveness of Fire Resistance Clothing (FRC)and should not be applied to this clothing. If working in FRC, employees can use Permethrin as it has been shown not to reduce the effectiveness of FRC. Permethrin will need to be applied to FRC well in advance of the planned work. If permethrin is unavailable employees can apply DEET to their skin and let dry prior to putting FRC on. o Oil of Lemon Eucalyptus is a plant-based insect repellent on the market as Repel Lemon Eucalyptus. The products have been proven to be effective against mosquitoes, deer ticks, and no-see-ums for up to six hours. Derived from Oil of Lemon Eucalyptus, this non- greasy lotion or spray has a pleasant scent and is not known to be toxic to humans.The spray or lotions will be effective for approximately two to six hours and should be reapplied every two hours to sustain protection. Lemon Eucalyptus products cannot be applied to fire retardant clothing. o Permethrin is an insecticide with repellent properties registered with the Environmental Protection Agency and recommended by the CDC. ■ Permethrin is highly effective in preventing tick bites when applied to clothing, but is not effective when applied directly to the skin.Two options are available for Permethrin treatment of clothing worn during field work: 1)pre-treatment of fabric by the clothing manufacturer; or 2) manual treatment of their personal clothing using Permethrin spray in accordance with recommendations manufacturers recommendations.This will likely require treatment at home or the office prior to field mobilization. Caution should be used when applying Permethrin as it is highly toxic to fish and house cats. AECOM strongly recommends the first option (employees obtaining pre-treated clothing)to avoid the time required, potential risk, and housekeeping issues involved with manually treating the clothing with spray. Purchase pre-treated clothing in accordance with S3AM-208-PR1 Personal Protective Equipment and with the approval of your Supervisor or Manager. ■ The Permethrin pre-treatment is odorless and retains its effectiveness for approximately 25 washings.After 25 washings, the pre-treated clothing will be Wildlife,Plants&Insects(S3AM-313-PR1) Revision 6 July 31,2019 PRINTED COPIES ARE UNCONTROLLED.
