Introduction
Protection of the environment is a key political issue in Europe and elsewhere. Protection of the environment
is taken in a very broad sense. What is meant is the total life cycle aspects of, e.g. a product on the
environment, including expenditure of energy and during all phases from mining of raw materials, fabrication,
packaging, distribution, use, scrapping, recycling of materials, etc. However, assessment of all aspects of the
welded product or structure during its entire lifetime cycle is beyond the scope of the present document. The
document is limited to aspects directly related to welding fabrication.
The design of the fabricated structures puts a lower limit on the expenditure of energy during joint preparation
and welding, on the consumption of consumables and consequently on emissions of fumes and gases during
welding, etc. but the design phase is not covered by the document.
Welding fabrication has many environmental aspects. This document provides for a checklist, which may be
used for identification of environmental aspects during welding fabrication.
Provisions have to be restricted to a general guidance. Limit values are specified in national laws.
Some of the environmental aspects also have an implication for occupational health and safety, but the check
list in this document is incomplete for this use.

1 Scope
This document provides check lists for the assessment of the environmental aspects of welding fabrication of
metallic materials including site and repair work. Informative annexes indicate recommended actions for
avoiding and reducing the possible environmental impacts outside the workshop.
2 Normative references
Not applicable.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
welding fabrication
welding fabrication includes (for the purpose of this document) the following activities and associated
processes:
− joint preparation including thermal cutting and grinding;
− surface preparation including sand blasting, shot blasting, shot peening, chemical pickling and
cleaning;
− welding, including grinding and back gouging;
− soldering and brazing;
− thermal spraying;
− preheating and heat treatments;
− flame straightening and mechanical straightening;
− inspection and testing of welds and thermal sprayed surfaces.
3.2
disposal
collection, sorting, transport and treatment of waste as well as its storage and tipping above or under ground,
the transformation operations necessary for its re-use, recovery or recycling [Directive 75/442/EEC]
3.3
environment
surroundings in which an organization operates, including air, water, land, natural resources, flora, fauna,
humans and their interrelation [EN ISO 14001:2004]
3.4
environmental aspect
element of an organization's activities or products or services that can interact with the environment
[EN ISO 14001:2004]

3.5
environmental impact
any change to the environment, whether adverse or beneficial, wholly or partially resulting from an
organization's environmental aspects [EN ISO 14001:2004]
4 Procedures
Requirements for the protection of the environment during welding fabrication can originate from a number of
sources such as:
– legal requirements, often at the national level;
– commercial requirements (customer requirements);
– economical requirements, e.g. related to insurance.
Annex B provides further comments on the possible requirements.
Absolute limits, e.g. emissions, can apply but protection of the environment is, as a general rule, a continuous
process for which gradual improvements are aimed.
The check lists in the document can be used as a tool for determination of possible problem areas. In general
this applies to the following situations:
– when planning a fabrication, the application of new methods of fabrication or new equipment;
– for identification of procedures for monitoring or checks of actual environmental aspects;
– for specification of procedures for handling, storage and disposal of environmentally harmful substances.
All check lists state possible environmental aspects. Many aspects can be identified during the planning stage
as having no environmental impact. Others can be shown to be of no significance by monitoring or checking
the production processes. A few can result in further action to comply with the requirements. Annex A
provides some general guidance for assessment and possible actions.

5 Check lists of possible environmental aspects
Table 1 — Common to welding fabrication
Common to welding fabrication
Consumables Check for:
- Disposal of containers, packaging material, etc.;
- Disposal of used consumables and waste materials.
Equipment Check for:
- Energy and fuel efficiency;
- Generation of physical aspects, e.g. noise, heat and
radiation;
- Requirements for spare parts and consumables for
maintenance;
- Procedures for disposal of the equipment.
Work operation Check for:
- Disposal of scrap;
- Emission of fumes, gases and aerosols;
- Energy and fuel consumption;
- Fire hazards and explosion risks whenever there is a
risk of ignition;
- Generation of physical aspects, e.g. heat, light,
noise, radiation.
NOTE Several of the aspects listed above have a limited range of influence. It
depends on the circumstances whether they represent an environmental aspect or not.
Noise may e.g. not represent an environmental aspect when working in a large workshop
but may be a serious problem when working on site or performing repair work in
residential areas.
