Generators are frequently used to supply electrical power on construction sites. While convenient and often necessary, generators frequently produce noise levels that are hazardous to those working in their vicinity. Quieter generators use one or more of the following to reduce sound levels: mufflers, sounds absorbing insulation, barriers and baffles.

Use of quieter generators can reduce noise exposures from the generator to less than 85 decibels, the OSHA action level. It is likely exposures from other equipment and tools will still necessitate participation in a hearing conservation program and the use of hearing protection.

Shindaiwa kWiet Power Generators

• Fuel: diesel
• Output, 1 phase (switchable): 120, 127, 139, 240, 254, 277 volts
• Output, 3 phase (switchable): 208, 220, 240, 416, 440, 480 volts
• Air dams and insulated panels redirect cooling air, doubling the length-of-travel to minimize airflow noise without the need for power-robbing auxiliary fans.
• The enclosure features heavy-gauge steel and sound-absorbing foam insulation. The result is lower sound levels as well as increased unit rigidity.
• Specially-tuned muffler and a longer exhaust pipe improve the balance of high and low noise frequencies.
• Standard features: Voltage, frequency, amperage and hour meters; automatic voltage regulator; oil pressure and water temperature gauges; battery charge warning indicator.
• Options: Electronic governors (standard on DGK150D), electronic auto-start modules, battery chargers and block heaters. A variety of trailers, fuel tanks and trailer accessories are available.

Lower noise levels may reduce hypertension, stress and fatigue, and increase the concentration and mental performance of workers. Improved worker health, comfort and concentration may lead to greater productivity. Quieter generators eliminate the work and time required to construct standalone noise barriers and enclosures and allow placement closer to work areas.

The use of diesel and particularly gasoline-powered equipment poses the risk of carbon monoxide exposure, especially in areas where airflow is reduced. Steps to control exposure are important because the gas is invisible, odorless and tasteless. Small, inexpensive personal monitors should be worn by the operator to warn of unacceptable exposures.
