In all operations in+ol+ing the mi/ing and pumping of flamma!le and
com!usti!le fluids there is a heightened risk of fire% Precautions must

6eneral precautions to take:
4'uipment should !e place in such a position to minimiEe the flo" of the
flamma!le fluid past any ignition sources during the operations%
Geep all non(in+ol+ed personnel stationed at the muster point or safe area%
4/cept for the persons operating the e'uipment, no person is permitted to !ein the restricted access area during mi/ing and pumping of flamma!le fluid%
*top all engines and other ignition sources that are not necessary for the
pumping operation%
Do not place any flamma!le fluids in pump unit displacement tanks% 1lear communication is re'uired in case of emergency%
