Prevention Strategies:  Testing air quality.  Ventilation and monitoring.  Training and rescue plans. Facility Safety: Lockout/Tagout (LOTO) (April 10, 2025) Definition:  Technique to prevent energy release during equipment servicing by isolating energy sources with locks and tags. Types of Hazardous Energy:  Electrical, mechanical, hydraulic, pneumatic, thermal, and chemical. Steps for LOTO Procedure: 1. Identify energy sources. 2. Shut down equipment. 3. Isolate equipment. 4. Apply lockout/tagout devices. 5. Release stored energy. 6. Verify isolation. Importance:  Prevents injuries from unexpected energy releases. Facility Safety: Electrical Safety (April 24, 2025) Three Primary Electrical Hazards:  1. Shock: Current passing through the body. 2. Arc: High-energy discharge causing burns. 3. Blast: Pressure wave and shrapnel. Ohm’s Law:  V = IR (Voltage = Current × Resistance). Effects of Current on the Body:  1–3 mA: Tingling sensation.  9–25 mA: Muscular contractions.  60 mA: Ventricular fibrillation. Controls:  Grounding equipment.  Insulated tools and PPE.  Use of GFCIs in wet environments. Key Prevention Strategies:  Enclose energized parts.  De-energize equipment when possible.
