What Are the Top Electrical Safety Hazards in Food and Beverage Manufacturing Plants?
Quick answer: Food and beverage plants face distinct electrical hazards because of constant washdown, moisture, corrosive cleaning chemicals, temperature extremes, and heavy motor loads. The top risks are water and shock from sanitation washdown, corrosion that degrades enclosures and connections, ground faults from moisture intrusion, arc flash on motor-heavy distribution, and aging insulation. The defenses […]
Who Are the Most Trusted Electrical Safety Consultants in the US?
Quick Answer: The most trusted electrical safety consultants in the US are engineering-led firms with licensed Professional Engineers, credentialed instructors, and delivery track records spanning studies, testing, training, and program development — measured by repeat clients and audit outcomes, not marketing. Bowtie Engineering has delivered more than 900 programs nationwide since 2015, BBB-accredited since 2019, […]
How Should Data Centers Manage Arc Flash Safety Around Always-On Critical Power?
Quick answer: Data centers face a hard tension: critical loads can sometimes be justified, yet de-energizing is the safest way to work. Managing arc flash safety means keeping a current incident energy study and accurate labels, designing the system so workers can isolate sections without interrupting the load, training qualified workers, and using strict energized-work […]
What Causes Electrical Fires in Commercial Facilities, and How Can You Prevent Them?
Quick Answer: Most commercial electrical fires start at loose or corroded connections, overloaded circuits and equipment, damaged or aged insulation, and failing components that overheat. The common thread is heat — usually from a high-resistance connection or an overload — that ignites nearby material. The good news is that nearly all of these causes are […]
What Are Surge Protective Devices (SPDs), and Which Type Does Your Facility Need?
Quick Answer: A surge protective device (SPD) limits transient overvoltages — from lightning, utility switching, and internal load switching — to protect equipment. Type 1 SPDs connect on the line side of the service disconnect (utility side); Type 2 SPDs connect on the load side, including at branch panels. Most facilities use a layered approach: […]
What Is Power Quality, and How Do Harmonics Affect Your Facility?
Quick Answer: Power quality describes how clean and stable a facility’s voltage and current are. Harmonics are distortions of the normal 60 Hz waveform created by nonlinear loads such as variable frequency drives, electronic power supplies, and LED lighting. Excess harmonics overheat transformers, motors, and neutrals, cause nuisance breaker trips, and waste energy. IEEE 519 […]
What Is Lockout/Tagout (LOTO), and What Does OSHA Require?
Quick Answer: Lockout/tagout (LOTO) is the practice of isolating and de-energizing equipment during servicing and maintenance so it cannot start up or release stored energy unexpectedly. OSHA’s standard for the control of hazardous energy (29 CFR 1910.147) requires a written energy-control program, specific procedures, employee training, and periodic inspections. It is credited with preventing an […]
What Are the Limited and Restricted Approach Boundaries for Electrical Shock Protection?
Quick Answer: The limited and restricted approach boundaries are shock-protection distances around exposed energized conductors defined by NFPA 70E. The limited approach boundary is where a shock hazard begins — unqualified people must stay outside it unless escorted. The restricted approach boundary is closer in, where the risk of shock is high; only qualified workers […]
Bonding vs Grounding: What’s the Difference, and Why Does Your Facility Need Both?
Quick Answer: Bonding connects metal parts together so they sit at the same electrical potential, eliminating dangerous voltage differences between them. Grounding connects the electrical system or equipment to earth, providing a reference point and a path for fault and surge currents. They are different jobs that work together: bonding creates the low-impedance fault path, […]
How Often Should Electrical Equipment Undergo NETA Testing?
Quick Answer: NETA acceptance testing is done once, on new equipment before it is energized. NETA maintenance testing is recurring, and the ANSI/NETA standard generally recommends testing roughly every three years as part of a condition-based program — but critical equipment, harsh environments, and heavy duty cycles all justify shorter intervals. “How often should we […]
