Wright Construction specializes in the construction of communications towers for various cell carriers. On one of the company’s recent projects, there was one fatality. Workers have reported several injuries since then. In light of this situation, the company is redoubling its efforts to prevent accidents, also known as industrial hygiene. Name three potentially fatal accidents that could occur during the construction of a communication tower and the corresponding health effects workers might experience (acute, chronic, local, or systemic). Also, identify the corresponding OSHA standard that would help the company prevent the accident from occurring, including any relevant personal protective equipment.

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
