Blast Wave

The overpressure wave traveling outward from an explosion point. (CCPS, 1996, no. 22)

Blast resistant buildings

Buildings that are structurally designed to withstand an explosion generated load (pressure and impulse) while sustaining a predetermined amount of damage.

Blast Load

The load applied to a structure or object from a blast wave, which is described by the combination of overpressure and either impulse or duration.

Blast

A transient change in the gas density, pressure, and velocity of the air surrounding an explosion point. The initial change can be either discontinuous or gradual. A discontinuous change is referred to as a shock wave, and a gradual change is known as a pressure wave.

Blanketing

The technique of maintaining an atmosphere that is either inert or fuel-enriched in the vapor space of a container or vessel. Also called Padding.

Biosafety level

A specific combination of work practices, safety equipment, and facilities designed to minimize the exposure of workers and the environment to infectious agents.

Biological Oxygen Demand

The amount of dissolved oxygen in water, given in lbs. (kgs) or % that is consumed by biological oxidation of a chemical

Benchmark

A point of reference from which measurements may be made or from which other things can be measured. A program that is used to compare the operation of two or more systems is called a benchmark program.

Bench Scale

Technical laboratory scale (typically between 0.1 and 5 dm3), more specifically directed to process simulation and determination of technical plant facilities (cooling/heating capacities, temperature constraints, charging requirements, etc.)

Behavior-based safety program

A program designed to provide frequent feedback to personnel regarding their safety behaviors in the workplace.
