FRH hydraulic fluid may contain tricresyl phosphate which, if taken
internally, can produce paralysis. Hydraulic fluid may be absorbed
through the skin. Wear long sleeves, gloves, goggles, and faceshield. If
FRH gets in eyes, wash them immediately and get medical aid
immediately. If FRH gets on skin, thoroughly wash with soap and
water. Wash hands thoroughly prior to eating or smoking. Application
