The MSDS of BP2197 states it contains between 1 and 5% TCP. The fact is that it actually does not contain quite as much as Mobil Jet II but you should still use the same precautions.
I know some people would perhaps consider not using gloves or masks (when required) but my recommendation would be to always air on the side of caution when using ANY Engine Oil or Hydraulic fluid. If supplied then use PPE and if not supplied then request it and be extra vigilant especially when handling used oil.
