Exposure to electric current is one of the many hazard sources during arboricultural operations. But electricity is one of the most unforgiving of these sources. A review of utility data shows that one in four contacts that resulted in an [...]

This is a continuation of the discussion of the electrical-system equipment found along distribution lines. One of the requirements for arborists working in proximity to an electrical hazard – within 10 feet of the lines – is familiarity with the [...]

Photo 1: If we transmitted the electricity at the voltage generated at the power plant, the voltage has the force to move only tens of miles. Transformers are used to step up the voltage so it can be moved hundreds [...]

Mathematics is not a field that sparks much interest among tree workers – or people in general. But the field of probability plays a role in just about everything tree workers do. If you knew that the odds of being [...]
