Hand light
Visual display of information and system condition status that is visible to the wearer (NFPA 1981).
HUD - Heads up display
A test performed by filling pressure-containing components completely with water or other incompressible fluid while expelling all contained air, closing or capping all open ports of the pressure-containing components to a prescribed value through an externally supplied pressure-generating device to verify its strength against unwanted rupture (NFPA 1901 and 10)
Hydrostatic testing
Any condition that would pose an immediate or delayed threat to life, cause irreversible adverse health effects, or interfere with and individual’s ability to escape unaided from a hazardous environment (NFPA 1670)
Immediately dangerous to life and health

LED’s/Light emitting diodes
The US federal agency responsible for research and development on occupational safety and health issues.
NIOSH
An insert inside the facepiece of an SCBA that fits over the user’s mouth and nose
Nose cups
The US federal agency that regulates worker safety and, in some cases, responder safety. It is part of the US department of labour
Occupational Safety and Health Administration (OSHA)
An SCBA in which the exhaled air is released into the atmosphere and is not reused
Open-circuit self-contained breathing apparatus (SCBA)
A device that continually monitors for lack of movement of the wearer and automatically activates an alarm signal, indicating the wearer is in need of assistance; can also be manually activated to trigger the alarm signal (NFPA 1982)
PASS alarm (Personal Alert Safety System)
Consists of full personal protective clothing, plus a self-contained breathing apparatus (SCBA) and a personal alert safety system (PASS) (NFPA 1001)
PPE
The standard unit for measuring pressure.
PSI
An air-purifying respirator that uses a powered blower to force the ambient air through one or more air-purifying components to the respiratory inlet covering (NFPA 1984)
PAPR - Powered Air Purifying Respirator
A device that measures and displays pressure readings. In an SCBA it indicates the quantity of breathing air that is available at any time
Pressure Gauge
A part of a fire fighters PPE that is designed to be worn over the head and under the helmet; it provides thermal protection for the neck and ears.
Protective Hood
A system that allows emergency replenishment of breathing air to the SCBA of disabled or entrapped fire or emergency services personnel (NFPA 1407)
Rapid Intervention Crew/Company (RIC) universal air connection
A device or devices designed to bypass a regulator
Regulator Bypass Valve
The complete assembly, including the respiratory inlet covering air purification components, electronics, batteries, harness, cables and hose where applicable; designed to protect the wearer from inhalation of atmospheres containing harmful gases, vapors or particulate matter (NFPA 1994)
Respirator
The backpack or frame for mounting the working parts of the SCBA and the straps and fasteners used to attach the SCBA to the fire fighter
SCBA Harness
The part of the SCBA that reduces the high pressure in the cylinder to a usable lower pressure and controls the flow of the air to the user
SCBA Regulator
An atmosphere-supplying respirator that supplies a respirable air atmosphere to the user from a breathing air source that is independent of the ambient environment and designed to be carried by the user (NFPA 350 and 1981)
Self-contained breathing apparatus (SCBA)
A respirator with an independent air supply that is used by underwater divers.
