Benefit from the expert knowledge of Keller Lufttechnik

Please find here an overview of relevant standards and guidelines in the field of air pollution control. Please do not hesitate to contact us!

 

TA-Luft: Air pollution control - emission standards

The TA Luft defines limit values of airborne pollutants in exhaust air operation, including the total dust volume, as well as fine dust content. It is important to comply with either the mass flow or mass concentration limits as set forth.  In this brochure, Keller Lufttechnik lists some limit values for you.

VDI 2262-3: Air quality in the workplace - clean air recirculation

Regulation VDI 2262-3 provides information about air pollution control measures to minimize exposure to pollutants in the workplace. It is particularly important for clean air recirculation because the limit values are strictly defined for this purpose.

TRGS 900: Occupational limit values in the workplace

The TRGS 900 includes a list of materials with limit values for the workplace. Compliance with these limit values will safeguard the health of workers who are exposed to inhaled pollutants. The air quality in the workplace must demonstrate that the limit values are not exceeded. Therefore, reliable extraction systems and air pollution control efforts are required in many cases.

TRGS 560: Air recirculation after processing carcinogenic dust

Since the beginning of 2012 the current TRGS 560 diective applies to air recirculation of carcinogenic dust. Mandatory measures and levels of separation are specified here for potential air recirculation.

TRGS 561: Processing of carcinogenic metals

The TRGS 561 establishes the limit values for the processing of carcinogenic metals. The dusts generated by these processes are subject to strict regulations.

TRGS 528: Welding operations

Regulation TRGS 528 applies to welding or cutting of metals that may produce hazardous gaseous or particulate emissions. Welding of stainless steel produces carcinogenic Cr(VI) compounds.

DGUV-Regel 109-001 (fomerly: BGR 109): Grinding, brushing and polishing of aluminum

This regulation applies to the grinding, brushing and polishing of aluminum at processing machines and related facilities. It refers only to the associated fire and explosion hazards. As a rule, wet scrubbers or dry separators with constructive explosion protection are recommended for these applications.

DGUV-Regel 109-011 (formerly: BGR 204): Magnesium processing

This regulation is for the handling of magnesium, especially during processing, filling, decanting, removing, or storing. The magnesium can occur as shavings, dust or sludge. As a rule, wet scrubbers are used for these applications.

2014/34/EU (formerly: ATEX 114): Explosion Protection Directive for Manufacturers

Guideline 2014/34/EU of the European Parliament and of the Council (commonly referred to as ATEX 114) is aimed primarily at manufacturers. The guideline pertains to protection systems and any machinery and units that are located in a potentially explosive environment. Included in this context are both electrical and non-electrical equipment that may have their own potential ignition source.

EN 1127-1: Explosive environments

This European standard is a customary explosion protection document. It sets out procedures for detecting and assessing hazardous situations that can lead to explosions, and describes appropriate planning and manufacturing safeguards.

TRBS 727: Avoiding ignition hazards created by electrostatic charges

Electrostatic charges can create ignition sources, which in turn can set off dust explosions.The TRBS 727 outlines precautionary measures such as grounding.

VDI 2263-6: Fire and explosion protection for dust extraction systems

The VDI 2263-6 Guideline specifically pertains to dust extraction systems. To adopt suitable protection measures, Keller Lufttechnik complies with the explosion/fire protection measures described herein.
