This proposal is to enable a second international congress on Wood Dust to be held in conjunction with the American Industrial Hygiene Association Conference & Exposition in May, 2011, in Portland, OR.
The first International Wood Dust Congress – Challenges to Occupational Risk Assessment & Management, was held on October 25-27, 2006 in Strasbourg, France, sponsored by the Institut National de Recherche et de Sécurité (INRS). This proposal is to enable a second international congress to be held in conjunction with the American Industrial Hygiene Association Conference & Exposition in May, 2011, in Portland, OR. NIOSH will follow the CDC policy on “Securing Approval for Sponsorship of Conferences” and “Guidance for Collaboration with the Private Sector”. The Project officer, Dr. Harper, successfully managed organization of a similar ASTM International Johnson Conference on “Size-Selective Aerosol Sampling to meet ISO Conventions” July 16-19, 2007. It is expected that the wood dust conference will last two days and will feature high quality research from many world-wide institutions. Dr. Peter Görner, INRS, and Dr. Martin Harper, NIOSH, will be co-Chairs, and will form the nucleus of a scientific committee to review invited abstracts and put together the agenda. Carol Tobin, AIHA, will be the Staff Member contact. US wood products stakeholders, including the American Forest & Paper Association and the National Council for Air and Stream Improvement have agreed to collaborate in ensuring a successful conference. Funding from NIOSH will be mainly used to sponsor the travel of the co-Chair and five key-note speakers to address the five themes of the conference: particle characteristics and sampling; exposure assessment; human health effects and biological mechanisms; risk assessment; and risk management and control.
The most significant impact will be the presentation of a joint US-French position on the most appropriate sampling methodology for wood dust. A follow-up question as to which companies implement this recommendation in their in-house hygiene programs will be asked of corporate industrial hygienists from companies that are members of the American Forest & Paper Association when they meet at the Forest Products Industrial Hygiene forum at AIHCE 2012 in Indianapolis, IN.
Wood dust is implicated in an increased prevalence of certain workplace respiratory symptoms, such as bronchitis, loss of pulmonary function, reactive airways disorders, including asthma, and nasal mucociliary stasis, nasal obstruction, and cuboidal metaplasia leading to sino-nasal adenocarcinoma. However, the mechanism of action of wood dust at the molecular, cellular or tissue level to produce these symptoms is not well understood. Recent estimates for 25 countries in Europe suggest 3.6 million workers are exposed to wood dust. In France, Decree No. 2003-1254 set an inhalable limit value for wood dust in workplaces at 1 mg/m3 to come into force in 2005. The American Conference of Governmental Industrial Hygienists confirmed the same value as their threshold limit value (TLV) for wood dust in 2005, and the NIOSH Recommended Exposure Limit (REL) is also 1 mg/m3.
62% of all exposed workers (2.2 million) in Europe are thought to be exposed above this value and both the numbers of workers exposed and the exposure levels are considered to be similar in North America (USA and Canada). One of the largest agricultural sectors in the USA is forestry for lumber and paper production. 9% of the total population of workers exposed to wood dust work in forestry and sawmilling.
