29、In 1976, the American Welding Society published the first edition of AWS F1.1, Method for Sampling Airborne Partic-ulates Generated by Welding and Allied Processes, in recognition of the need to standardize the procedure for samplingcontaminants in the welders breathing zone. The Project Committee o

30、n Fumes and Gases, using expertise in welding aswell as industrial hygiene, developed the technique through field testing. Minor modifications and editorial changeswere made in the 1985, 1992, 1999, and 2006 editions.In 1987, the first edition of AWS F1.5, Methods for Sampling and Analyzing Gases fr

31、om Welding and Allied Processes,was published to complement AWS F1.1. Minor modifications and editorial changes were made in the 1996 and 2003editions.In 2009, a decision was made to combine these two standards into a single document so that information needed to accu-rately assess welder exposure i

32、n the workplace would be found in one document. This document describes commonlyaccepted industrial hygiene sampling techniques but no longer includes the actual analytical methods as recommendedby the National Institute of Occupational Safety and Health (NIOSH) and the Occupational Safety and Healt

33、h Admin-istration (OSHA). The analytical methods are readily available and are not generally needed by industrial hygienistcollecting exposure assessment samples in the workplace. Instead, these analytical methods are referenced only.Comments and suggestions for the improvement of this standard are

34、welcome.

This standard describes procedures for sampling fumes and gases generated by welding and allied processes.Because

43、it is limited to health hazard evaluation, the standard is primarily concerned with sampling at the workersbreathing zone (see 4.1). It also describes procedures for general area sampling of fumes and gases. The sampling methodsdescribed in this standard apply to the sampling of solid particulate ma

44、tter as well as the gases liberated during weldingand allied processes. Gases generated during welding may include, but are not limited to, the following:(1) Ozone (O3)(2) Carbon Monoxide (CO)(3) Nitric Oxide (NO) + Nitrogen Dioxide (NO2) = Oxides of Nitrogen (NOx)(4) Gaseous FluoridesThis publicati

45、on is intended for use by personnel who are responsible for sample collection and evaluation of the envi-ronment of personnel involved with welding and allied processes. It provides the most widely recognized, safe methodsfor the sampling to be used in the evaluation of airborne concentrations of fu

46、mes and gases commonly formed duringwelding. Where appropriate, analytical methods have been referenced.While not generally present around most welding operations, it is possible to encounter toxic phosgene gas wheredegreasing or cleaning activities involving chlorinated hydrocarbons are carried out

47、 in close proximity to welding. Anti-spatter compounds may also contain chlorinated hydrocarbons. When vapors from these materials enter the atmospherearound the arc, a reaction between ultraviolet radiation from the welding arc and these vapors can produce phosgene.Since phosgene levels as low as 2

48、 ppm can cause serious health impairment or even death, it is important to preventvapors from any chlorinated hydrocarbon from entering the welding area. Consult the Safety Data Sheet (SDS) for anycleaning products used in close proximity to welding processes. Sampling for phosgene is outside the sc

49、ope of the proce-dures described in this standard.This standard makes sole use of the International System of Units (SI).1.2 Safety.
