How often should SCBA operational readiness checks be performed?

The correct practice for SCBA operational readiness checks is to perform them before each use. This ensures that the equipment is functioning properly and is in good working condition prior to entering environments where breathing might be compromised, such as hazardous areas or during firefighting operations. Checking the SCBA before each use involves verifying that the air supply is adequate, the mask is free from damage, and all components are well-maintained. This proactive measure significantly enhances the safety and effectiveness of personnel who rely on this equipment, as it helps to prevent malfunctions at critical moments.

While other options mention different intervals for checks, they do not align with best practices aimed at ensuring immediate readiness. Weekly or monthly checks could miss problems that arise suddenly or can fail to catch issues that develop between uses. After each use checks, while important for maintenance, would not ensure readiness prior to an imminent response or deployment. Therefore, pre-use checks are essential for optimal safety and performance.
