aluminum within a year
Design pressure
Ans: the maximum gauge pressure that a pressure vessel, device,
component, or system is designed to withstand safely under the temperature
and conditions of use
Dispensing
, 3 Exampromax - Stuvia US 2025/2026
Ans: the pouring or transferring by other means of any material from a
container, tank, or similar vessel, which would release dusts, fumes, mists,
vapors, or gases to the atmosphere, unless such release is prevented by a
device, equipment, or system designed for that purpose
Educational laboratory unit
Ans: a laboratory unit that is used for educational purposes for students
through the twelfth grade

Exhausted enclosure
Exampromax - Stuvia US
Ans: a device, typically consisting of a hood equipped with a fan that
serves to capture and exhaust fumes, mist, vapors, and gases generated at a
workstation or other local environment. Does not include a room provided
with general ventilation
Explosion
Ans: an effect produced by the sudden violent expansion of gases, whether
or not accompanied by a shock wave or disruption, of enclosing materials
Explosions include the effects of the following sources:
Ans: 1. Chemical changes such as rapid oxidation, deflagration or
detonation, decomposition of molecules, and runaway polymerization
2. Physical changes such as pressure tank ruptures
3. Atomic changes (nuclear fission or fusion)
