• Description:
  Ear plugs are a good example of Personal Protective Equipment (PPE) used in various occupational settings. They are selected not only for their fit into the ear canals but also for their ability to reduce the level and frequency content of unwanted sounds, which is indicated in the value of their Noise Reduction Rating (NRR). This NRR value helps to make the selection process much easier for the health and safety professional who may need to make selections based on various noise exposure characteristics. In order to choose appropriate PPEs, it is a good idea to understand what the hazardous sources are and how its propagations can be reduced. When hand-transmitted vibration (HTV) from power tools becomes a significant issue in the work place, tool vibration measurements and health risk assessments can be carefully conducted following ISO 5349-1, ISO 5349-2, and ISO 8041. Ideally, based on these vibration measurements and risk assessments, appropriate vibration-reducing (VR) gloves could be identified from variety of commercially available gloves. ISO 10819 evaluates the actual effectiveness of a VR glove and utilizes the frequency weighting factors [W(h)] defined in ISO 5349 in its transmissibility calculations but the outcomes from both these standards cannot be directly related. ISO 5349 specifies a frequency range from 6.3 to 1,250 Hz, while ISO 10819 specifies a frequency range from 25 to 1,250 Hz and is missing six low-frequency 1/3-octave band frequencies (6.3, 8, 10, 12.5, 16, and 20 Hz) that are considered to be extremely important for assessing and characterizing HTV exposures. A previous study showed that the frequency response of a glove can be modeled as a Linear Time-Invariant (LTI) System and that transmissibility results do not differ when conducting ISO 10819 assessments using various vibration excitation spectrums. Given this information, it is possible to simply characterize vibration exposures to a gloved hand by using the frequency signature of a tool and the transmissibility information of a glove or, more specifically, overlap ISO 5349 tool assessments with ISO 10819 glove evaluations. In this study, a simple protocol was developed as a practical method for glove selection that uses previously captured tool vibration and glove transmissibility spectrums to quickly estimate the effectiveness of a glove in reducing tool-specific vibration.
