Several government programs encourage the installation of EV charging stations. Many facilities add them as a perk to employees who drive hybrid and electric vehicles. EVs rely heavily on lithium-ion batteries, which present several hazards. Overheating can cause a chain reaction known as thermal runaway, leading to fires or explosions. Manufacturers must implement robust thermal management systems to prevent this. EV batteries operate at high voltages, increasing the risk of electrical shock. Safety protocols and protective gear are essential for technicians working on these charging installations.
The expansion of EV charging infrastructure brings its own set of safety concerns. Improperly installed or damaged charging stations can pose significant electrical risks. Regular inspections and adherence to safety standards are crucial. As EV charging stations become more connected, they are potential targets for cyberattacks. Protecting the infrastructure from such threats is vital to ensuring the reliability and safety of the charging network.
REVISIT YOUR SAFETY PROTOCOLS AND TRAINING
Electricians, overhead line workers and engineers are at a higher risk of being exposed to electrical hazards due to their work. However, anyone who works with or around electricity can be at risk of being injured by an electrical hazard. Adding additional electrical installations and their support infrastructure can expose additional workers to common electrical hazards. This includes people who work close to energized equipment or power lines and those who work in wet or damp locations.
INSPECT FREQUENTLY, REPAIR IMMEDIATELY
The frequency of inspections for electrical equipment depends on the type and usage of the equipment. For example, portable tools should be inspected before each use, while heavy-duty machinery may require more frequent checks.
In general, it is recommended to have a licensed electrician perform a thorough inspection of all electrical systems and equipment at least once a year. However, certain factors, such as the age and condition of the equipment, its usage patterns, and any previous incidents or repairs, may require more frequent inspections.
Even between routine inspections, workers are the best source of identifying hazards presented by the tools they use every day. If you notice any of the following signs, stop using the equipment immediately and consult a qualified electrician:
- Visibly Damaged Wiring: Frays, cuts, or nicks in wiring insulation can pose serious electrical
- Scorching or Discoloration Around Outlets or Switches: This usually indicates overheating, excessive electrical load, or faulty
- Frequent Tripping of Circuit Breakers: Circuit breakers protect your electrical system by shutting off during an Frequent tripping suggests a problem that needs attention.
- Persistent Burning Odors: A constant or recurring burning smell without a discernible source could indicate an electrical fire starting within your walls.
- Hot Outlets or Switches: Switches or outlets that feel hot to the touch signal an electrical problem that can lead to failure or
- Buzzing or Crackling Sounds: These noises may indicate faulty electrical connections, potentially leading to arcing and sparking.
- Flickering or Dimming Lights: While occasional flickering can be harmless, persistent flickering might signal a deeper electrical issue.
Recognizing these warning signs can help prevent dangerous electrical incidents through timely maintenance and repairs.
UPDATE YOUR ELECTRICAL PPE & TRAINING
Personal protective equipment (PPE) is vital in minimizing the risk of electrical injuries for workers handling or exposed to electrical hazards. PPEs such as insulated gloves, flame-resistant clothing, face shields and protective eyewear are designed to provide a barrier against electrical shocks, burns and arc flashes.
Since PPE comes with different safety ratings, make sure that your facility stocks equipment suitable to the changing energy profile of the work being done. Remember, while PPE significantly reduces the risk, it is not a substitute for proper electrical safety practices and should be used with other preventive measures.
The proper use and maintenance of PPE are crucial for electrical safety. Ensuring that all PPE meets appropriate Occupational Safety and Health Administration (OSHA) safety standards and is regularly inspected for damage or wear is vital. Make sure your training covers all the necessary bases to keep workers safe:
- Selection of Suitable Electrical PPE: Choose the proper PPE based on the electrical tasks to be performed.
