Airborne Hazards Safety Standards Airborne Hazards Safety Standards address the dangers posed by fumes, gases, vapors, and particles released into the air during welding processes. Looking at procedures for measuring emission rates, sampling airborne particles in a welder’s breathing zone, collecting fumes for analysis, minimum requirements for airflow rates, and so forth, airborne hazards safety standards cover safety procedures starting from the emission of hazardous materials all the way through to their removal.

ISO 10882-1:2011

Health and safety in welding and allied processes - Sampling of airborne particles and gases in the operators breathing zone - Part 1: Sampling of airborne particles

ISO 10882-1:2011 specifies a procedure for sampling airborne particles in the breathing zone of a person who performs welding and allied processes (the operator). It also provides details of relevant standards that specify required characteristics, performance requirements and test methods for workplace air measurement, and augments guidance provided in EN 689 on assessment strategy and measurement strategy. ISO 10882-1:2011 also specifies a procedure for making gravimetric measurements of personal exposure to airborne particles generated by welding and allied processes (welding fume) and other airborne particles generated by welding-related operations. Additionally, it provides references to suitable methods of chemical analysis, specified in other standards, to determine personal exposure to specific chemical agents present in welding fume and other airborne particles generated by welding-related operations. The general background level of airborne particles in the workplace atmosphere influences personal exposure and therefore the role of fixed-point sampling is also considered.

ISO 10882-2:2000

Health and safety in welding and allied processes -- Sampling of airborne particles and gases in the operators breathing zone -- Part 2: Sampling of gases'

The following gases and vapours which can be produced or be present during welding and allied processes are covered: ozone (O 3 );carbon monoxide (CO);carbon dioxide (CO 2 );nitric oxide(NO)and nitrogen dioxide(NO 2 );vapours produced in the welding or cutting of metals having paint or other surface coatings. Fuel, oxidant and shielding gases used in welding and allied processes are not covered. The general background level of gases and vapours in the workplace atmosphere influences personal exposure, and therefore the role of fixed point measurements is also considered.

ISO 15011-1:2009

Health and safety in welding and allied processes - Laboratory method for sampling fume and gases - Part 1: Determination of fume emission rate during arc welding and collection of fume for analysis

ISO 15011-1:2009 defines a laboratory method for measuring the emission rate of fume from arc welding. It also defines a method of collecting the fume for subsequent analysis and refers to suitable analytical techniques. The methods described are suitable for use with all open arc welding processes except tungsten inert gas (TIG) welding, which produces little fume.

ISO 15011-2:2009

Health and safety in welding and allied processes - Laboratory method for sampling fume and gases - Part 2: Determination of the emission rates of carbon monoxide (CO), carbon dioxide (CO2), nitrogen monoxide (NO) and nitrogen dioxide (NO2) during arc welding, cutting and gouging

ISO 15011-2:2009 defines laboratory methods for measuring the emission rates of carbon monoxide (CO), carbon dioxide (CO 2 ), nitrogen monoxide (NO) and nitrogen dioxide (NO 2 ) generated during arc welding, cutting and gouging, using a hood technique. The methodology is suitable for use with all open arc welding processes, cutting and gouging, but different designs of hood are used depending on the process and whether or not it can be conducted automatically.

ISO 15011-3:2009

Health and safety in welding and allied processes - Laboratory method for sampling fume and gases - Part 3: Determination of ozone emission rate during arc welding

ISO 15011-3:2009 defines a laboratory method for measuring the emission rate of ozone during arc welding, using a hood technique. The method is directed primarily at measuring ozone emission rate when using gas-shielded arc welding processes, but it can also be employed with other processes, e.g. self-shielded flux-cored arc welding, provided that welding can be performed automatically under the hood.

ISO 15011-4:2006

Health and safety in welding and allied processes - Laboratory method for sampling fume and gases - Part 4: Fume data sheets

ISO 15011-4:2006 covers health and safety in welding and allied processes. ISO 15011-4:2006 specifies requirements for determination of the emission rate and chemical composition of welding fume in order to prepare fume data sheets.. It applies to all filler materials used for joining or surfacing by arc welding using a manual, partly mechanised or fully automatic process, depositing unalloyed steel, alloyed steel and non-ferrous alloys. Manual metal arc welding, gas-shielded metal arc welding with solid wires, metal-cored and flux-cored wires and arc welding with self-shielded flux-cored wires are included within the scope of ISO 15011-4:2006.

ISO 15011-5:2011

Health and safety in welding and allied processes - Laboratory method for sampling fume and gases - Part 5: Identification of thermal-degradation products generated when welding or cutting through products composed wholly or partly of organic materials using pyrolysis-gas chromatography-mass spectrometry

ISO 15011-5:2011 specifies procedures for obtaining information about thermal degradation products generated when welding, cutting through, preheating and straightening metal treated with coatings composed wholly or partly of organic substances, e.g. shop primers, paints, oils, waxes and inter weld materials such as adhesives and sealants. It is aimed primarily at test laboratories performing such procedures. The data generated can be used by coating manufacturers to provide information for inclusion in safety data sheets and by occupational hygienists to identify thermal degradation products of significance in the performance of risk assessments and/or workplace exposure measurements. The data cannot be used to estimate workplace exposure directly. ISO 15011-5:2011 is applicable to all coatings composed partly or wholly of organic materials that can be heated, during welding and cutting, preheating and straightening to temperatures at which thermal degradation products are generated and where it is not apparent what those degradation products are.

ISO/TS 15011-6:2012

Health and safety in welding and allied processes - Laboratory method for sampling fume and gases - Part 6: Procedure for quantitative determination of fume and gases from resistance spot welding

ISO/TS 15011-6:2012 provides guidance on determination of emission rates of fume and gases generated by spot welding of uncoated and coated steel sheets, expressed as the quantity of pollutants per spot weld. It describes the test principle and considers methods for sampling and analysis. ISO/TS 15011-6:2012 can be used for determining the influence of the type of material, the coating system, and the material thickness on the possible generation of fume and gases when using a fixed combination of electrodes, welding equipment, and testing conditions. The data generated can be used by product manufacturers to provide information for inclusion in safety data sheets and by occupational hygienists to evaluate the significant substances emitted by spot welding in the performance of risk assessments and/or workplace exposure measurements.

ISO 15012-1:2013 specifies a method for testing equipment for the separation of welding fume in order to determine whether its separation efficiency meets specified requirements. The method specified does not apply to testing of filter cartridges independent of the equipment in which they are intended to be used. ISO 15012-1:2013 applies to equipment that is manufactured after its publication.

ISO 15012-2:2008

Health and safety in welding and allied processes - Requirements, testing and marking of equipment for air filtration - Part 2: Determination of the minimum air volume flow rate of captor hoods and nozzles

ISO 15012-2:2008 specifies a method for establishing the minimum air volume flow rate required for captor hoods and nozzles to effectively capture fume and gases from welding and allied processes. The method can be used with capture devices of any aspect ratio and cross-sectional area, but it is not applicable to on-gun extraction systems and down draught tables. ISO 15012-2:2008 also specifies the test data to be marked on the capture devices.
