Guideline for exposure to dangerous exhaust fumes European Garage Equipment Association (EGEA) The European Garage Equipment Association aisbl was formed in 1980 and regroups 11 national professional associations representing the interests of both manufacturers and importers of garage equipment. EGEA objective is to provide more influence, better information and stronger support to the garage equipment industry throughout Europe! The following organizations are represented within the EGEA: Austria AVL DiTest (Member Company) Belgium FMA - Fédération du Matériel pour l’Automobile France GIEG - Groupe des Industries 'Equipements de Garage Germany ASA - Bundesverband der Hersteller und Importeure von Automobil-Service Ausrüstungen Italy AICA - Associazione Italiana Costruttori Autoattrezzature Netherlands RAI - AUTOVAK Rijwiel- en Automobiel-Industrie Norway ABL - Autobransjens Leverandørforening Poland STM - Stowarzyszenie Techniki Motoryzacyjnej Spain AFIBA - Asociación de Fabricantes e importadores de Bienes de Equipo Para La Automoción Sweden FVU - Fordons Verkstads Utrustarna Switzerland SAA - Swiss Automotive Aftermarket United Kingdom GEA - The Garage Equipment Association Guideline for exposure to dangerous exhaust fumes For country specific legislations please visit the EGEA webpage.

Exhaust Extraction Guideline EGEA The hazards of combustion exhaust emissions Exposure to hazardous vehicle exhaust emissions in the working area is a serious health risk. Diesel exhaust contains over 100 individual hazardous chemical components, that when combined can result in as many as 10,000 chemical compounds. Some examples of hazardous chemical components in exhaust gasses: Benzene Group 1A Carcinogen to humans Polynuclear aromatic hydrocarbon Suspected human carcinogenic Hydrocarbon Group 2A Suspected human carcinogenic Benzene “alpha” pyrene Group 2A Suspected human carcinogenic Formaldehyde Group 2A Suspected human carcinogenic Benz furan Group 2B Suspected human carcinogenic Carbon monoxide Life threatening to humans Nitric oxides Life threatening to humans The individual substances may lead to permanent health complications, especially diesel engine emissions can course cancer. (source: BAuA, Germany) General recommendations Inhaling combustion exhaust emissions indoors should be avoided if possible If this can not be guaranteed, the workplace should be equipped with an exhaust extraction system to protect the worker against healthy dangerous substances The exhaust fumes should be captured at source which means directly at the exhaust tailpipe. The exhaust nozzle or funnel should be designed that 100% of the exhaust emission can be captured Exhaust extraction systems should work with under pressure The extraction volume should be 25% above the maximum emitted exhaust volume The extraction volume should be adopted by the biggest possible engine Extraction volumes Formula to calculate the needed extraction volume: V = Vh x n x 0,0363 x 1,25 V = Volumetric extraction airflow required (m³/h) Vh = Cubic capacity of the vehicle to be tested (liter) n = Test speed of vehicle (rpm) 0,0363 = Physical conversion factor 1,25 = 25% proportion of fresh / ambient air Approximate values of recommended extraction volumes Cars up to 4 liters engines with max. 2500 rpm = 450m³/h (normal service) Cars up to 4 liters engines with max. 5000 rpm = 900m³/h (exhaust tests) Trucks up to 16 liters engines with max. 1300 rpm = 1000m³/h ( normal service ) Trucks up to 16 liters engines with max. 2500 rpm = 1800m³/h ( exhaust tests ) For other applications like performance tests or special vehicles please use the formula to define the needed extraction volume.
