Predictive maintenance involves techniques that monitor the condition of equipment to anticipate failure before it occurs. Common predictive techniques include:

Vibration monitoring (1) – Detects imbalance, misalignment, or bearing wear.

Oil analysis (2) – Identifies contamination, wear particles, or breakdown in lubricants.

Ultrasound (4) – Detects leaks, arcing, and mechanical friction.

PM frequency analysis (3) is part of preventive maintenance, not predictive maintenance.

A Ground-Fault Circuit Interrupter (GFCI) continuously monitors the current balance between the “hot” and “neutral” conductors. If an imbalance greater than about 5 milliamps occurs (indicating leakage current flowing to ground), the GFCI trips instantly to protect personnel from shock.

Correct (D): Current – GFCIs detect differences in current between conductors.

Incorrect: Resistance (A), Voltage (B), and Power (C) are not directly monitored by GFCIs.

EPA and OSHA define regulated medical waste (RMW) as waste that is saturated or dripping with blood or other potentially infectious materials (OPIM).

B. Blood-saturated gauze (Correct): Meets the definition of RMW.

A. Fluorescent bulbs: Considered hazardous universal waste (mercury), not RMW.

C. Urine-soaked pads: Not classified as RMW unless visibly contaminated with blood.

D. Home-use sharps: Not regulated by EPA as medical waste from households.
