Why is proper LOTO (Lock Out Tag Out) crucial before commencing work in waterjetting?

Proper Lock Out Tag Out (LOTO) procedures are crucial before commencing work in waterjetting to prevent the accidental energizing of equipment. Waterjetting involves the use of high-pressure water streams, which can be extremely dangerous if equipment is inadvertently activated while personnel are working in proximity to it.

By implementing LOTO, all sources of energy feeding into the equipment are effectively locked out, ensuring that workers are protected from unexpected machine start-ups or the release of stored energy. This procedure mitigates the risk of severe injuries, making it a fundamental safety practice in hazardous environments like those encountered in waterjetting operations.

Other considerations, while relevant to workplace safety and efficiency, do not directly address the paramount concern that LOTO aims to resolve. Ensuring workflow efficiency or protecting from dust may enhance working conditions, but they do not provide the critical safety protections that LOTO delivers against the risks associated with energized equipment. Similarly, improving visibility in the workspace is beneficial but does not relate to the specific dangers presented by active machinery.
