Safe work practices and environments are critical to HVM. We have safety committees and safety officers at both the corporate and divisional levels. We maintain detailed safety records on each and every job and review safety procedures regularly.

We place great importance on accident prevention. The degree of safety and the results accomplished are directly proportional to the effort expended to control conditions, practices and human actions that lead to accidents.

Safety Program

Following are the major components of our Safety Program:

  • Safety Manual
  • Training and Retraining
  • Safety Meetings
  • Safety Records
  • Safety Equipment
  • Safety Compliance

HVM conducts on-going (at least annually) safety audits to determine that each employee is complying with the safety-related work practices required.

Safety Rulings

HVM has an OSHA incident rate of 1.8, and zero lost work days (2007-2008), and a history of no disabling injury or death since our inception in 1960.

Test Equipment & Calibration

Accurate test results depend on a comprehensive program of test equipment maintenance and calibration. HVM adheres to the NETA Acceptance Testing Specifications and Maintenance Testing Specifications for equipment calibration.

All of HVM’s test equipment is checked on a regular basis against documented national standards. Equipment found to be out of calibration is withdrawn from use until corrected, re-tested and found acceptable.

Test Instrument Calibration

  • HVM has a calibration program that assures all applicable test instruments are maintained within rated accuracy.
  • The accuracy is directly traceable to the National Institute of Science and Technology (NIST).
  • Instrumentation is calibrated in accordance with the following frequency schedule.
  • Field Instrumentation: Analog, 6 months maximum; Digital, 12 months maximum.
  • Laboratory Instrumentation: 12 months
  • Leased Specialty Equipment: 12 months where accuracy is guaranteed by lessor.
  • Dated calibration labels are placed on all test equipment.
  • Records, which show date and results of instruments calibrated or tested are kept at HVM.
  • Up-to-date instrument calibration instructions and procedures are maintained for each test instrument.
  • Calibrating standards of higher accuracy than that of the instrument tested are used to calibrate our test equipment.
  • Accuracy of metering in test equipment shall be appropriate for the test being performed but not in excess of 2% of the scale used.
  • Waveshape and frequency of test equipment output waveforms shall be appropriate for the test and tested equipment.

Industry Associations

HVM actively participates in national and international standards associations such as:

  • The National Fire Protection Association (NFPA)
  • The American National Standards Institure (ANSI)
  • The Institute of Electrical and Electronics Engineers (IEEE)
