"Those who cannot remember the past are condemned to repeat it."
—Harvard Professor George Santayana

Although much has been written in safety literature about the necessity of learning from past accidents and near-misses, very few countries keep detailed records of lab accidents, and under-reporting remains a widespread problem in organizations worldwide.

The list below has been compiled from public databases and official sources, such as the U.S. Chemical Safety and Hazard Investigation Board, as well as from verified tips from individuals.

If you have information concerning any of these lab fatalities or others, please email info@labsafety.org. To ensure the integrity and completeness of this list, all reports received will be verified before being published. Please allow 4-6 weeks for new listings to appear.

Only fatalities that are the primary or secondary result of accidents that occurred in academic or industrial laboratory settings or in the course of conducting scientific field work are included. When multiple causes of death are possible or where the cause of death is uncertain, this is noted.

Lab Safety Memorial Wall Poster SetThe Laboratory Safety Institute encourages anyone who works in a lab to freely reference this list in safety meetings and presentations. This list is also available in print as a 6-poster set.
