How long can someone be in a loud noise before it's hazardous?
The degree of hearing hazard is related to both the level of the noise as well as to the duration of the exposure. But this question is like asking how long can people look at the sun without damaging their eyes.
Occupational hearing loss is one of the most common work-related illnesses in the United States.
Each year, about 22 million U.S. workers are exposed to hazardous noise levels at work. Over 30 million U.S. workers are exposed to chemicals, some of which are harmful to the ear (ototoxic) and hazardous to hearing. In addition to damaging workers’ quality of life, occupational hearing loss carries a high economic price to society.
OSHA Injury and Illness Recordkeeping and Reporting Requirements
Many employers with more than 10 employees are required to keep a record of serious work-related injuries and illnesses on OSHA Form 300: “Log of Work-Related Injuries and Illnesses”. (Certain low-risk industries are exempted.) Minor injuries requiring first aid only do not need to be recorded.
