Therefore, control of the fumes and gases generated is to be exercised to minimize worker exposure.The
41、most effective method of control is to capture the fumes and gases close to their source before they enter a workers breathing zone or the general workplace environment.Ventilation equipment used to capture the fumes and gases is to be fit for purpose because inefficient capture could result in high
42、 exposure and can be detrimental to workers health. It is important therefore that it adheres to defined manufacturing, materials and design requirements and gives warning of malfunction.This part of ISO 15012 defines the general requirements that are necessary for ventilation equipment to maintain
43、exposure to fumes at acceptable levels.This part of ISO 15012 is a type-B standard as stated in ISO 12100.This part of ISO 15012 is of relevance, in particular, for the following stakeholder groups representing the market players with regard to machinery safety: machine manufacturers (small, medium
44、and large enterprises); health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).Others can be affected by the level of machinery safety achieved with the means of this part of ISO 15012 by the above-mentioned stakeholder groups: machine users/employers (sm
45、all, medium and large enterprises); machine users/employees (e.g. trade unions, organizations for people with special needs); service providers, e.g. for maintenance (small, medium and large enterprises); consumers (in case of machinery intended for use by consumers).The above-mentioned stakeholder
46、groups have been given the possibility to participate at the drafting process of this part of ISO 15012.In addition, this part of ISO 15012 is intended for standardization bodies elaborating type-C standards.The requirements of this part of ISO 15012 can be supplemented or modified by a type-C stand
47、ard.For machines which are covered by the scope of a type-C standard and which have been designed and built according to the requirements of that standard, the requirements of that type-C standard take precedence.5DIN EN ISO 15012-4:2016-11 EN ISO 15012-4:2016 (E) 1 ScopeThis part of ISO 15012 defin

It applies to the design and manufacture of all parts of the equipment including hoods, ducting, filter units, air movers, systems that inform of unsafe operation and wo

It does not cover electrical, mechanical and pneumatic hazards.This part of ISO 15012 is applicable to the following: local exhaust ventilation systems (LEV); mobile and stationary equipment.This part of ISO 15012 is not applicable to the following: general ventilation, air make up or air movement s
