The standard is JB/T 8526-1997 "Safety Specification for high voltage water jet cleaning operations". The standard is formulated for the safety requirements of high voltage water jet cleaning operations, covering pre-operation equipment inspection, personnel protective equipment (such as pressure clothing, goggles, etc.), operation process specifications (pressure control, injection direction), environment security evaluation (electrical equipment waterproofing, site isolation) and emergency measures. By clarifying the key points of risk prevention and control in high voltage environments, prevent personnel injuries, equipment damage and secondary accidents, provide technical guidance for the safe implementation of high voltage water jet cleaning operations, and apply to the safety management and operation specifications of related cleaning operations in the industrial field.
