ABSTRACT
In the production of electrical transformers, dielectric test must be performed to certify the transformer will function properly in the field. These tests are conducted in a high voltage test lab (HVTL) where voltages can reach in excess of 500,000 volts. This health and safety assessment was performed on a HVTL to identify potential safety and health hazards within the lab and apply engineering controls, administrative controls and personal protective equipment to mitigate the hazard. This assessment was accomplished through the use of risk assessment, ...view middle of the document...

1. INTRODUCTION
Electrical transformers are one of the main components in providing the electricity that drives virtually every aspect of daily life. The electrical transformers role in this is performing the transformation of voltages from high to low which permit the transmission of the electricity throughout the nation. To insure proper operation, the transformer must follow strict testing procedures outlined in various ANSI/IEEE Standards. The required testing is carried out in a specially designed High Voltage Test Lab (HVTL). Within the confines of the HVTL, workers are exposed to a variety of hazards that are normally found in factories everywhere. In addition to common hazards such as noise pollution, slips, extreme temperature and others, there is also the presence of extreme high voltage exceeding 500,000 volts and currents exceeding 6000 amps. Considering a mere 50 volts or 30 milli-amps is enough to kill an average person, it is easy to understand the necessity of a thorough health and safety program which is followed by employees as well as management.

The focus of the study presented in this paper was to identify any health and safety hazards in the HVTL and mitigate these hazards by means of administrative controls, engineering controls and personal protective equipment. The HVTL used for this study is located at the ABB transformer factory in Crystal Springs; Ms. The HVTL is a 1600 square foot room with an enclosed generator room and a test office. Transformers enter the HVTL by means of two roller beds and one raised dock. The transformers are moved around the lab by a battery powered walk-behind fork truck. Cleaning of the transformers is accomplished using high pressure heated water mixed with an industrial degreaser and dried by means of compressed air. Testing is carried out by three lab technicians under the supervision of the test lab manager. According the Bureau of labor statistics (BLS) the industry standard for DART is 1.8 (BLS, 2013). Currently...
