Oil, gas, and chemicalsDec 24, 2020

GB 39800.2—2020: read PPE provision for oil, chemical, and natural-gas work by job

GB 39800.2—2020 is China's PPE provision part for oil, chemical, and natural-gas industries. It provides an industry lens for discussion, while each site, unit, and job still needs specific hazard identification.

Provision principlesDec 24, 2020

GB 39800.1—2020: general PPE provision starts with job risk

GB 39800.1—2020 is the general part of China's PPE provision series. It is a useful entry point for organizing provision logic, not a replacement for industry-specific parts, product standards, or site risk assessment.

Arc thermal hazardMay 28, 2018

IEC 61482-2:2018: arc clothing addresses thermal hazards, not every electrical-work risk

IEC 61482-2:2018 provides requirements and test methods for protective-clothing materials and garments where electric-arc thermal hazards may occur. IEC explicitly excludes shock, noise, light, pressure, hot oil, and several head/face/hand/foot risks.

Arc protectionMay 28, 2018

IEC 61482-2:2018 scope: an arc rating is not a complete site-safety plan

IEC lists IEC 61482-2:2018, Protective clothing against the thermal hazards of an electric arc. It provides a scope for discussing arc-thermal clothing, but it does not replace work permits, equipment state, isolation, or site risk controls.

Industrial launderingDec 6, 2017

ISO 15797:2017: testing logic for industrially laundered workwear and the service boundary

ISO 15797:2017 addresses test procedures for workwear intended for industrial laundering. It provides an evaluation pathway, not an operating procedure for a particular laundry, and does not automatically prove performance under actual service conditions.

Care managementDec 6, 2017

ISO 15797:2017: align industrial-laundering procedures with performance-retention scope

ISO lists ISO 15797:2017, Industrial washing and finishing procedures for testing of workwear. For centrally laundered workwear, test procedures help frame questions, but laundry contracts, contamination types, repairs, and retirement rules still need project-specific definition.

General requirementsJul 4, 2013

ISO 13688:2013 reminder: general requirements are not hazard-specific protection

ISO lists ISO 13688:2013, Protective clothing — General requirements. It can provide shared language for baseline information and design review, but it should not be treated as a substitute conclusion for arc, chemical, heat, or other specific hazards.

International standardJul 4, 2013

ISO 13688:2013: general protective-clothing requirements are not a stand-alone hazard rating

ISO 13688:2013 covers general requirements such as ergonomics, innocuousness, sizing, ageing, compatibility, marking, and manufacturer information. ISO states that it should be used with standards for specific protective performance.

High visibilityMar 1, 2013

ISO 20471:2013: high visibility is a separate requirement, not flame or arc protection

ISO lists ISO 20471:2013, High visibility clothing — Test methods and requirements. For road, night, or complex construction conditions, visibility should be specified separately; it does not replace clothing-performance assessment for other hazards.

High visibilityMar 1, 2013

ISO 20471:2013: high-visibility clothing requires a system of color, retroreflection, and material placement

ISO 20471:2013 concerns high-visibility clothing intended to signal the wearer's presence in daylight and under vehicle headlamps. It addresses color, retroreflective performance, minimum areas, and material placement.
