What is the primary hazard associated with hydraulic fluid (Skydrol) used in transport-category aircraft?
Answer: It is severely caustic and can cause chemical burns to skin and eyes
Skydrol is a phosphate-ester fluid that is highly caustic; skin and eye contact causes severe chemical burns requiring immediate flushing.
