OSHA has released two new Safety and Health Information Bulletins warning of potentially serious workplace hazards. “Preventing Hearing Loss Caused by Chemical (Ototoxicity) and Noise Exposure” was published in conjunction with the National Institute for Occupational Safety and Health. This bulletin provides recommendations to employers and safety professionals about identifying ototoxicants in the workplace and establishing hearing conservation programs where these chemicals cannot be replaced.“Avoiding Underground Utilities during Horizontal Directional Drilling Operations” highlights the hazards associated with striking different underground utilities. Horizontal directional drilling has reduced visibility compared to vertical drilling. The bulletin was based on an incident that led to an explosion at a nearby restaurant that resulted in a worker fatality.
