During manufacturing of equipment, wind energy employers need to look at the spaces that workers enter to determine if they meet OSHA’s definition of a confined space. By definition, a confined space:
Wind energy employers also need to look at the hazards of the confined spaces to determine whether those spaces are “permit-required” confined spaces (PRCS). By definition, a PRCS has one or more of these characteristics:
The configuration of all Nacelles will classify them as confined spaces and during the maintenance activities inside the Nacelles, workers may be exposed to hazards from electrical motors, gears, etc. Those hazards may classify a Nacelle to be a PRCS. Technicians working in Nacelles should make sure to perform air sampling (such as for low oxygen levels or other hazardous gases) prior to entering a Nacelle. It is recommended that the technician should always carry a portable gas monitor in their toolkit and make sure that it is maintained properly.
For further information on confined space hazards, OSHA's page on Confined Spaces should be consulted.
