Introduction

The safe operation of testing laboratories may involve hazards such as electrical, mechanical, non-ionizing radiation, ionizing radiation, chemistry, microbiology and ergonomics.

GB/T 27476 is a testing laboratory safety standard formulated for these risk factors, aiming to improve the safety management of testing laboratories

capabilities and safety technology capabilities to reduce the safety risks of testing laboratory operations.

GB/T 27476 is proposed to consist of 7 parts.

--- Part 1.General. The purpose is to give the general requirements for the safety of the testing laboratory, and provide a basis for the safety management of various risk factors in the laboratory.

provide guidance.

--- Part 2.Electrical factors. The purpose is to give the safety requirements related to electrical factors in the testing laboratory and improve the electrical safety of the laboratory.

Air safety, minimize personal injury and prevent property damage.

--- Part 3.Mechanical factors. The purpose is to give the safety requirements of the testing laboratory related to mechanical factors, reduce or eliminate the

room mechanical risks.

--- Part 4.Non-ionizing radiation factors. The purpose is to give the safety requirements of testing laboratories related to non-ionizing radiation factors, to prevent

prevent injury from these radiations or other harms from the use of these radiations.

--- Part 5.Chemical factors. The purpose is to give the safety requirements of the testing laboratory related to chemistry, and to prevent the chemical safety of the laboratory.

accidents and reduce laboratory chemical safety risks.

--- Part 6.Ionizing radiation factors. The purpose is to give the safety requirements related to ionizing radiation factors in the testing laboratory to prevent industrial

Accidents in which workers are unnecessarily exposed to radiation and other personnel may be harmed by ionizing radiation.

--- Part 7.Ergonomic factors. The purpose is to give the safety requirements of testing laboratories related to ergonomic factors, eliminate or reduce

Physical discomfort and injury of laboratory workers due to ergonomic factors.

Testing Laboratory Safety

Part 7.Ergonomic factors

1 Scope

GB/T 27476.7-2022 covers the ergonomic side of safety in a testing laboratory - the management requirements, which follow the general part of the series, and the technical requirements: identifying the hazards and assessing the risk, then working through personnel, facilities and environment, equipment, and materials. Ergonomic harm in a laboratory is slow, and that is why it goes unaddressed. Nobody is injured at a moment anyone can point to; instead a bench at the wrong height, a workstation that forces an awkward reach, poor lighting at a task that demands close vision, long periods standing at an instrument, and the repeated manual handling of sample containers accumulate into strain and into the fatigue-driven mistakes that cause the other kinds of laboratory accident. The clauses treat the laboratory as a workplace to be designed rather than merely equipped: the people who work in it and how they are prepared, the room and its environment, the instruments and benches they work at, and the materials that have to be lifted, carried and stored. Part 7 of the GB/T 27476 series, written for those designing or refitting a laboratory at a fixed location and for the safety officers who assess one; laboratories elsewhere may use it for reference.

This document specifies the safety requirements for testing laboratories (hereinafter referred to as "laboratories") related to ergonomic factors.

This document is applicable to the ergonomic design and evaluation of the safety of laboratories with fixed locations. Laboratories in other locations can refer to it.
