Language detection techniques are described. The slurry may include an organic dispersion agent, and preferably has a has a pH in the range of about 4 to about 12. The actuatable foot rest system may further include a remotely actuated retention mechanism that includes an actuator disposed remote from the foot rest member and which maintains the foot rest member in the first position and, when remotely actuated using the actuator, releases the foot rest member from the first position. In the event that after conclusion of the variable delay time period an arc discharge is detected, a second countermeasure for the suppression of arc discharges is executed.
