Fiberglass insulation is the fact that fluffy, typically pink stuff that looks somewhat like cotton candy on a paper backing. It is flexible so that you can tack it yourself in drafty attics together rafters and other air leaks in your home, but it includes a drawback — touching it working with it can leave small glass fibers onto your clothing or skin, causing irritation or even a rash. The particles are so small they are difficult to see on skin or on fabric, but you sure can feel them. Covering your body before working with insulation helps protect your skin from the itchy material.
Measure outdoors after finishing the insulation project while still wearing gloves, hat and full protective clothing. Brush off your clothing and hair along with your hands to remove as many contaminants as possible. Shake out the gloves, hat and coat, if wearing one. Remove invisible particles of fiberglass from your clothing using a shop vacuum cleaner or other vacuum cleaner not used for carpet cleaning (to stop the particles from becoming into the air on your living areas). Go indoors and remove the clothing by carefully turning every piece inside out as you remove it, to avoid touching fiberglass which may be inserted on the exterior of the clothing.
Wash your hands and face with warm soapy water, as well as your arms, even if they were subjected to the insulation at all. Have a shower or bathtub, washing your entire body with soap and warm water, as well as washing your hair or head. Towel yourself dry and place the towel in the dirty laundry.
Apply an excellent cream or coconut oil into your entire body and face, particularly areas that feel itchy. The liquid coating will help soothe and prevent itchiness. Apply more as needed. Wear clean clothing and shake the insulation project clothing briskly outdoors. Put it in the laundry and wash as normal, with no additional clothing in the washing machine, to prevent cross contamination. Dry the clothing in a dryer or line dry.
