Low Oil Shutdown:
Low oil shutdown is a mechanism that automatically shuts down the generator when oil levels are too low. This prevents engine damage caused by insufficient lubrication. A study by the American Petroleum Institute (API) indicates that running a generator without adequate oil can lead to significant mechanical failures. -
Surge Protection:
Surge protection safeguards against voltage spikes that can damage both the generator and electric tools. This feature works by diverting excess voltage to the ground. The Associated Press recently highlighted the need for surge protection as many portable generators lack this critical safety measure, leading to equipment damage. -
Fuel Type Safety Measures:
Generators can use various fuels, such as gasoline, propane, or diesel. Each fuel type presents different safety considerations. For instance, gasoline-fueled generators require proper ventilation to prevent carbon monoxide buildup. As per the CDC, around 400 people die from carbon monoxide poisoning linked to portable generators annually. -
Quiet Operation Features:
Quiet operation features reduce noise levels during generator use. This is not only a comfort concern but also a safety one. Loud noise can distract operators and create hazardous environments. Research from the World Health Organization (WHO) indicates that excessive noise exposure can lead to health problems, including stress and hearing loss.
