Blast criteria for open spaces and enclosures.

Area of Science:

• Military medicine
• Trauma research
• Environmental health

Background:

• Blast research has evolved significantly since before World War II.
• Understanding blast injury mechanisms and effects is crucial for personnel safety.

Purpose of the Study:

• To provide a comprehensive review of blast research history and findings.
• To describe mechanisms, injury types, and casualty/damage-risk criteria for blast exposure.
• To outline methods for assessing air blast dose and personnel protection strategies.

Main Methods:

• Historical review of blast research literature.
• Description of blast injury mechanisms and physiological effects.
• Analysis of casualty and damage-risk criteria for various exposure scenarios.
• Evaluation of protective measures and animal response data.

Main Results:

• Detailed description of blast injury mechanisms and injury types.
• Established casualty criteria for single blasts and damage-risk criteria for repeated blasts.
• Identified hazards of blast waves in open structures and foxholes.
• Presented methods for air blast dose determination and current protective garment efficacy.

Conclusions:

• The review synthesizes current knowledge on blast effects and protection.
• Provides essential criteria for assessing risks and ensuring safety in blast environments.
• Highlights the importance of continued research in blast injury and protection technologies.
