Question 1 of 30👑 VIP
Read the following passage carefully, then answer the question below. "Self-Contained Breathing Apparatus (SCBA) is mandatory personal protective equipment for firefighters operating in environments immediately dangerous to life or health (IDLH). A standard SCBA consists of a facepiece, a pressure-demand regulator, an air cylinder, and a harness assembly. SCBA air cylinders are typically rated at 2216 psi (low pressure), 3000 psi (high pressure), or 4500 psi (ultra-high pressure). The duration of the air supply depends on the cylinder capacity and the user's breathing rate under exertion; a 45-minute rated cylinder may provide significantly less air during heavy firefighting activity. SCBA units must be inspected before each use according to NFPA 1852, and out-of-service tags must be applied to any unit that fails inspection. The alarm on a SCBA activates when approximately 25% of the air supply remains, serving as a warning to the user to begin exiting the hazardous area immediately." According to the passage, when does the SCBA low-air alarm activate?
