A team of fire protection engineering researchers at Worcester Polytechnic Institute (WPI) is investigating the fire safety risks associated with green construction. The WPI team is working with a $1 million grant from the U.S. Department of Homeland Security, which will fund a three-year project aimed at identifying and reducing the potential for firefighter and occupant injuries and deaths that could be associated with unanticipated hazards posed by green building elements.
When it comes to low-voltage and AC and DC difference in shock risk, many workers may be confused. Low-voltage is not defined by OSHA in regards to electrical safety and severity of shock. Related to low-voltage potential is the difference between AC and DC shock risks.
The Occupational Health and Safety Blog covers this topic, looking at the work practices and training for the definition of low voltage. The blog gives specific references that seem to imply that the regulatory ranges are as follows: >600 volts = high voltage; 50–600 volts is low voltage; and <50 volts (sometimes referred to as “extra-low voltage”) is generally not regulated except by NEC.
Low Frequency Requirements: When, Where, and Why?
Did you know that as of January 1, 2014, a low frequency audible fire alarm signal is required in all sleeping areas of newly constructed hotel guest rooms and dormitory sleeping rooms?
