Gross Decontamination at Fireground Procedures
topic
Gross decontamination at the fireground uses large volume water rinsing of the exterior of turnout clothing and SCBA immediately upon exiting the hazard zone, removing a significant fraction of surface-deposited contaminants before they can migrate deeper into clothing layers or be transferred to the wearer's skin and vehicle surfaces during transport, with implementation of gross decontamination zones as standard fireground practice being a primary prevention strategy for reducing cumulative carcinogen exposure.
Role
Provides the most immediate and accessible contamination reduction intervention by removing surface contaminants before they can penetrate clothing or transfer to skin, with field studies demonstrating that gross decontamination within minutes of fire suppression significantly reduces contaminant concentrations remaining on clothing compared to delayed decontamination, establishing gross decontamination as a high-priority behavioural intervention for cancer prevention in structural firefighting.
