Wood dust exposure and risk of lung cancer
This study investigated whether a history of wood dust exposure through occupational and hobby-related activities was associated with increased lung cancer risk. It was conducted in the form of a population-based case-control study, with 440 cases and 845 age-matched controls. Using detailed work and personal histories, quantitative estimates of cumulative exposure to wood dust (thought to be primarily from softwood) were calculated for each participant. Using unconditional logistic regression adjusted for age and smoking status, risk of lung cancer was examined in relation to employment in wood-related occupations, working with wood as a hobby, as well as cumulative wood dust exposure that took into account both occupational and hobby-related sources. While an increased risk of lung cancer associated with working in a sawmill (odds ratio 5.1) was observed, there was no evidence of increased risks with other occupations, working with wood as a hobby or with estimated cumulative exposure to wood dust. Other findings are discussed.

Immunoglobulin E-mediated sensitization to pine and beech dust in relation to wood dust exposure levels and respiratory symptoms in the furniture industry
Wood dust exposure may cause imunoglobulin E (IgE)-mediated allergic diseases. The objectives of this study were to estimate pine and beech dust sensitization rates among woodworkers and a reference group, explore the association between exposure and sensitization and between sensitization and respiratory symptoms, and finally investigate the impact of proteinogenic specific IgE (sIgE) epitopes on respiratory symptoms. In a Danish study conducted in 52 furniture factories and two reference factories, workers' asthma and rhinitis status were evaluated using questionnaires and blood samples collected from 1506 woodworkers and 195 references. Workers with asthma symptoms (N=298), a random study sample (N=399) and a random rhinitis sample (N=100) were evaluated for IgE-mediated sensitization to pine and beech dust. The prevalence of pine and beech sensitization among current woodworkers was 1.7 and 3.1%, respectively. No differences in sensitization rates were found between woodworkers and references, but the prevalence of wood dust sensitization was dose-dependently associated with the current level of wood dust exposure. No relation was observed between wood dust sensitization per se and respiratory symptoms. Only symptomatic subjects had proteinogenic IgE epitopes to pine. Increased odds ratios for sIgE based on proteinogenic epitopes to beech and respiratory symptoms were found, although they were not statistically significant.

Underestimation of terpene exposure in the Nordic wood industry
This study determined that emission of sesquiterpenes from processed wood warrants attention in the work environment. Currently, only the monoterpenes in the terpene group are monitored in occupational hygiene studies. Terpene emissions are a work environment issue for industries that process wood, as they are known to cause respiratory difficulties and mucous membrane irritation. Fresh sawdust of the most common boreal conifers, Norway spruce (Picea abies) and Scots pine (Pinus sylvestris), was subjected to processing (drying), and the emissions were analyzed with a gas chromatograph-mass spectrometer. The data indicate that workers are exposed to significant amounts of sesquiterpenes, an observation that has not been recorded previously at wood processing plants. On average, the proportion of sesquiterpenes to monoterpenes was 21 ± 5% for spruce and 15 ± 5% for pine. The composition of terpenes emitted in air from spruce wood differs from the composition in resin. The sum of monoterpenes and sesquiterpenes can exceed the occupational exposure limit for turpentine for processes where monoterpene concentrations are already close to the occupational exposure limit, and for processes involving the processing of bark. Findings suggest that future studies of health effects from terpenes in air should measure monoterpenes and sesquiterpenes to assess whether the current OELs are appropriate.

Rubberwood dust and lung function among Thai furniture factory workers
The objective of this study was to assess factors affecting lung function among 685 workers in the rubberwood (Hevea brasiliensis) furniture industry in two provinces of eastern Thailand. Study data were gathered using questionnaires, by sampling wood dust and by spirometry. The mean wood dust exposure level in the factories was 4.08 mg/m3. The mean overall percent of predicted forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and FEV1/FVC values were 84%, 86% and 99%, respectively. Significant negative correlations were found between mean dust exposure levels and FVC and FEV1/FVC%, but not FEV1. An association between decline in lung function and wood dust levels among wood workers suggests that rubberwood dust exposure negatively affects lung function.

Health and working conditions in carpenter's workshops in Armenia (Colombia)
A study of the health and working conditions in 10 carpenter's workshops in the municipality of Armenia (Colombia) was conducted. Working conditions of the 177 most exposed workers were examined, and exposure to wood dust and noise, as well as lighting, were measured. The state of health was surveyed using a self-report questionnaire. Results show that personal protection was not used appropriately and that some were inadequate, that half of workshops had below the minimum allowable lighting limit level (500 lux) required, and that the noise level exceeded the permissible maximum limit value (85 dBA) in all the workshops.

Exposure-related human cancer: Molecular changes in sinonasal cancer and lung cancer, with focus on TP53 mutations
Carcinogenesis is driven by alterations in the sequence and function of the genes involved in many critical cellular processes. Understanding these molecular mechanisms can clarify the role and biological effects of these risk factors. In this thesis, mutations in the tumour suppressor gene, TP53, and their associations with exposure were studied in sinonasal cancer and lung cancer. Another important mechanism in cancer is inflammation, and its contribution was explored by analyzing the expression of the enzyme cyclooxygenase-2 (COX-2) in sinonasal cancer.

Occupational, domestic and environmental mesothelioma risks in Britain
There are just over 2100 people diagnosed with mesothelioma in the United Kingdom each year with about five times as many cases in men as in women In this study, more than 600 patients with mesothelioma and 1400 healthy people were interviewed to examine United Kingdom rates of the disease linked to different occupations. It was calculated that men born in the 1940s who worked as carpenters for more than 10 years before they reached the age of 30 have a lifetime risk for mesothelioma of about one in 17. For plumbers, electricians and decorators born in the same decade who worked in their trade for more than 10 years before they reached the age of 30, the risk is one in 50 and for other construction workers one in 125. For every case of mesothelioma, asbestos also causes about one case of lung cancer so the overall risk of asbestos related cancer for this particular group of carpenters is about one in 10. The risk was also increased in other industries and the study showed that two-thirds of all British men and one quarter of women had worked in jobs involving potential asbestos exposure at some time in their lives. There was also a small increased risk in those who had lived with someone who had been exposed to asbestos. The risk of mesothelioma for the rest of the United Kingdom population who haven't experienced these occupational exposures is about one in 1000. These apparently-unexposed cases account for 60 per cent of all mesotheliomas in women and 15 per cent in men. This is higher than the overall rate in women in most other countries, suggesting that many of these unexplained cases were caused by unrecognized environmental asbestos exposures which occurred in certain situations because of the widespread use of asbestos during the 1960s and 1970s.

The wood sector - Hazards and prevention
Le secteur du bois - Risques et prévention [in French]
The wood, cork and furniture sector in Tunisia employs 2% 0f the workforce, mainly in the transformation of raw materials. This work is often carried out in microentreprises, with poor supervision. Specific hazards include exposure to wood dust and work on dangerous equipment. Health effects may be carcinogenic, allergic or traumatic, the latter mainly targeting the hand. Occupational safety and health hinges mainly on monitoring dust levels, machine guarding, training and informing operators, and medical supervision according to suitable protocol.

Respiratory and skin effects of exposure to wood dust from the rubber tree Hevea brasiliensis
Potential health effects related to wood dust from the rubber tree have not been previously investigated. The aim of this study was to investigate the relations of rubber tree dust exposure to respiratory and skin symptoms, asthma and lung function. It involved 103 workers in a rubber tree furniture factory and 76 office workers in four factories in Thailand. All participants answered a questionnaire and performed spirometry. Inhalable dust levels were measured in different work areas. Furniture factory workers showed increased risk of wheezing, nasal symptoms and asthma compared to office workers. There was a dose-dependent increase in wheeze and skin symptoms in relation to dust level. There was a dose-dependent reduction in spirometric lung function with wood dust level. Other findings are discussed.

Wood dust particle and mass concentrations and filtration efficiency in sanding of wood materials
This study evaluated exposure to wood dust during sanding operations. The numbers of fine particles were low, less than 104 particles/cm3. This level is much lower than typical number concentrations measured in plasma arc cutting, grinding, and welding. Ultrafine particles less than 100nm were found during sanding of medium density plywood sheets. The importance of monitoring the efficiency of dust extraction systems is emphasized.

Occupational noise exposure and hearing protector use in Canadian lumber mills
In this study, a comprehensive noise survey of four lumber mills in British Columbia, Canada, using a randomized sampling strategy was carried out, resulting in 350 full-shift personal dosimetry measurements. Sound frequency spectrum data and information on hearing protector usage were also collected. A determinants-of-exposure regression model for noise was developed. The mean exposure level was found to be 91.7 dBA, well above the exposure British Columbia limit of 85 dBA. Of 52 jobs for which more than a single observation was made, only four were below the exposure limit. Twenty-eight jobs had means over 90 dBA, and four jobs had means over 100 dBA. Although the use of hearing protectors is high, it is unlikely that this provides complete protection against noise-induced hearing loss at the observed exposures.

Occupational exposure to wood dust and health effects on the respiratory system in a minor industrial estate in Bursa/Turkey
The aim of this study was to estimate occupational exposure to wood dust in the furniture industry in an industrial estate in Bursa, Turkey. The study involved 328 woodworkers and 328 unexposed controls. Data on respiratory health were collected by means of questionnaires and medical examinations, including spirometry. Exposure to wood dust was evaluated from workplace sampling. The average dust concentration at the workplace was 2.04mg/m3. 53.7% of the workers reported a blocked nose while working, 43.0% had eye irritation, 41.2% had itching eyes and 23.8% had a runny nose. No symptoms were observed in the control group while they were working at the workplace. The mean FEV1 and FVC values of woodworkers, among both smokers and non smokers, were significantly lower than those of controls. Implications of these findings are discussed.

Bilateral pneumothorax following acute inhalation injury
A male worker in an upholstery factory in Turkey was confined in the tanning machine for 15 min. On admission into hospital, he was confused with Glasgow coma scale score of 9. His vital signs were as follows: blood pressure 80/58 mmHg; pulse rate 114; respiratory rate 30 bpm; temperature 37.1°C; oxygen saturation 48%. Chest X-ray and bronchoscopy showed lung injury that warranted bilateral tube thoracotomy. The patient was discharged without any sequelae after eight days. Exposure to irritant gases such as sulfuric acid and sulfur dioxide can cause severe pulmonary injury.

Wood dust exposure and the risk of upper aero-digestive and respiratory cancers in males
The objective of this study was to examine the relationship between wood dust exposure and the risk of specific histological subtypes of upper aero-digestive tract and respiratory (UADR) cancers. A hospital-based examination was carried out to determine the effect of self-reported wood dust exposure on 1522 male UADR cancer cases and 1522 male controls, matched by age and smoking history. Regular wood dust exposure was found to be associated with a statistically significant increased risk of all UADR cancers (odds ratio OR 1.32), in particular of the nasal cavity, nasopharynx, and larynx, and of lung cancer alone (OR 1.69).

The development of an Australian database of wood dust exposures: Issues and future directions
This article discusses the feasibility of using existing data from various sources in order to assess exposure to wood dust in Australian industry. Information on the exposed workforce and wood usage was gathered from a combination of Australian Bureau of Statistics data and a telephone survey of a cross-sectional sample of woodworking enterprises in South Australia. However, it was found that many small businesses have not conducted exposure evaluations. In view of this limitation, it was concluded that targeted survey work, as has been conducted in the United Kingdom, which includes using national data, surveys and field measurements, is a more reliable strategy for exposure profile development and trend assessment.

Hazardous waste management in Chilean main industry: An overview
The new Chilean Hazardous Waste Management Regulation came into force on 12 June 2004. During the next 180 days (i.e., until 12 December 2004), each industrial facility was required to present a Hazardous Waste Management Plan if the facility generated more than 12 tons/year hazardous wastes or more than 12 kg/year acute toxic wastes. This article describes three case studies on the hazardous waste management plans carried out in facilities of the most important sectors of Chilean industrial activity: a paper production plant, a Zn and Pb mine and a sawmill and wood products facility. Hazardous wastes were identified, classified and quantified, minimization measures were implemented, and reuses and recycling options were evaluated.

Occupational risks for adenocarcinoma of the nasal cavity and paranasal sinuses in the German wood industry
To examine the risk of wood dust and chemical exposures for adenocarcinoma of the nasal cavity and paranasal sinuses (ADCN) among German woodworkers, a case-control study with 86 male ADCN cases and 204 controls was conducted in the German woodworking industries. Cumulative and average wood-dust exposure was quantified with a job-exposure matrix based on wood-dust measurements at recent and historical workplaces. Probabilities of exposure to wood preservatives, stains, varnishes, and formaldehyde were semi-quantitatively rated. ADCN occurred relatively more frequently among wood workers that had worked as cabinet makers or joiners than as saw millers. Average exposure to inhalable wood dust ≥5mg/m3 was associated with a high risk (OR 48.47) compared to levels below 3.5mg/m3. Exposure between 3.5 and 5mg/m3 was also found to pose a risk (OR 10.54). Exposure to pigment stains before 1970 was associated with an increased risk. No significant associations were estimated for wood preservatives, varnishes, and formaldehyde.

Longitudinal respiratory health study of the wood processing industry
This 5-year longitudinal study examined non-malignant respiratory effects of wood processing dust exposure. Personal dust samples were collected from ten wood processing plants. Spirometric tests were conducted on 1164 workers from these plants, who also responded to questionnaires on their state of health, smoking and occupational exposures. Regression analyses were used to evaluate the effect of exposure on annual change in FEV1, FVC, FEF25-75, and FEV1/FVC. It was found that exposure to wood solids was not associated with significant adverse effects. However the respirable fraction of other particulate matter was associated with obstructive or restrictive effects in some cases. Other findings are discussed.

Contents of this occupational information sheet on the job of cabinet maker: related occupations; description; place of work; work organization; tools and equipment; products, materials and persons concerned; work clothing; work and health. It is concluded that this occupation results in exposures of workers to physical hazards (noise, vibration, manual handling), chemical hazards (wood dust, formaldehyde-based glues, wood treatment products) and accidents (explosions, fire, dangerous equipment). These hazards require that individual and collective protective measures be reinforced and that workers be properly trained and informed.

Quality of life and employment status of workers with western red cedar asthma
The impact of current employment status and other factors on quality of life was evaluated for workers diagnosed with western red cedar asthma in British Columbia, Canada. Data were collected by means of structured telephone interviews. Among the 213 participants, employment status was the most consistent predictor of quality-of-life domains, with highest scores for employed subjects, particularly those who were no longer exposed to red cedar. Subjects who had quit work because of their asthma had worse scores, particularly for vitality and general health perceptions. Other factors independently associated with specific aspects of poor quality of life were having asthma-like symptoms, taking medication, and not being married.

Severe illness in furniture makers using a new glue: 1-Bromopropane toxicity confounded by arsenic
All four workers working with a new glue in a furniture factory were hospitalized following severe flu-like symptoms, which persisted three months later. Milder symptoms persisted in two workers eight years after their initial illnesses. Both have returned to work, while follow-up was unavailable for the other two workers. All available clinical records were reviewed. All four workers had high concentrations of serum bromide after exposure to glue containing 1-bromopropane (1-BP). All also had elevated urinary arsenic concentrations, the source of which remains unknown, but which confound interpretation of the abnormal bromide levels and clinical findings present during the acute illnesses.

OSHA compliance issues - Overexposure and control of methylene chloride in a furniture stripping operation
This OSHA inspection reports on a case of overexposure to methylene chloride in a small business involved in furniture repair and restoration employing 18 workers. The exposure occurred in a section of the establishment where a single employee worked three to four days per week removing paint and varnish from furniture by spraying methylene chloride. Personal sampling found short-term exposures and 8h TWA levels of 285-662ppm and 108ppm respectively, compared to permissible levels of 125ppm and 25ppm respectively. Recommendations included modifications in equipment design and local exhaust. Subsequent samplings showed drastic reductions in exposure levels which were well within permissible levels.

Occupational asthma - Carpentry and woodworking
Asthme au travail - Charpenterie et menuiserie [in French]
In order to adopt suitable measures for the prevention of occupational asthma and rhinitis, it is important to understand the health hazards in various vocational training and occupational settings. The IRSST published a leaflet presenting these two respiratory diseases in general terms (see CIS 08-514), together with six other leaflets covering specific occupational activities in more detail, explaining the risk factors and proposing suitable preventive measures. This leaflet specifically addresses occupational asthma and rhinitis in the carpentry and woodworking sector, together with the means of protection against specific allergens encountered in this work environment (wood dust, adhesives, solvents, isocyanates, silica).

Reducing formaldehyde emissions - Changes in the formulation of binders in particleboard manufacturing plants
Réduction de l'émission de formaldéhyde - Modification de la formulation du liant dans les usines de panneaux de particules [in French]
In partnership with the IRSST and with the collaboration of particle board manufacturers, the Forest Product Processing Research and Expertise Services (SEREX) of Quebec was given the assignment to optimize formaldehyde resins currently used by modifying their formulation so that their processing would give rise to lower levels of emissions. This project involved modifying commercial urea formaldehyde resins, producing panels in the laboratory and on an industrial scale, characterizing these panels and determining the concentration of formaldehyde in the gases emitted during resin modification and panel manufacture and degassing. Not only were the formaldehyde emissions reduced, but the quality of the panels was also slightly improved. The immersion tests also showed that the panels thus produced were more water resistant than the panels manufactured using conventional resins.

Noise reduction at band re-saws
The Control of Noise at Work Regulations 2005 (see CIS 06-1259) require employers to eliminate risks from noise, or to reduce them to the lowest possible level. This information note addresses the issue of noise reduction at band saws. The noise generated by band re-saws (typically over 85dB(A)) can be reduced by maintaining the machine and blade in good condition. Factors affecting the blade vibration level (the main source of noise) are listed along with advice on how the difference in noise levels when cutting and when idling can be used as a good indicator of the condition and adjustment of the machine and blade. The use of noise enclosures is also discussed. Replaces CIS 02-409.

Comparison of ergonomic risk assessments in a repetitive high-risk sawmill occupation: Saw-filer
The aims of this study were to compare the results of various ergonomic risk assessment methods, and to examine the association between the measure of risk obtained by applying these methods and incidence rates recorded in practice. Quantified physical exposure information collected from 15 saw-filers in four sawmill facilities was used to calculate the RULA, REBA, ACGIH TLV, Strain Index and OCRA procedures for various postures and efforts. Recorded incidence of upper extremity musculoskeletal injury in the saw-filer position ranged from 0.12 to 0.86 per person year worked. The assessment methodologies examined broadly agreed that a level of risk was associated with performance of the saw-filer job. The sensitivity of each of the risk assessment methods is discussed.

Airborne contact dermatitis in gaitas (flageolets) constructors after exposure to sawdust of caviuna
Exposure to the sawdust of exotic wood can produce dermatitis on exposed body areas among woodworkers. The cases of seven patients who made musical instruments in Spain from caviuna vermelha, part of the rosewood family, are described. They developed dermatitis on exposed areas hours after they had begun to work with caviuna. Patch tests were performed using the European standard series, caviuna sawdust samples and a series of dalbergiones. Fifteen unexposed controls were also tested. Caviuna samples were analysed by thin-layer chromatography. Patch test with caviuna sawdust yielded positive reactions in all subjects. Five of the seven subjects reacted strongly to obtusaquinine and (R)-4-methoxy-dalbergione deriving from Dalbergia retusa but also to sensitizers present in other rosewoods. Other findings are discussed.

Lung disorders of workers exposed to rush smear dust in China
A growing proportion of tatami mats are produced in the Zhejiang province of China for export to Japan. The mats are made from rush. One of the production steps requires smearing the freshly-cut rush with clay to prevent colour fading and increase strength. During subsequent steps, workers are heavily exposed to clay dust which contains 20-30% free silica and is therefore a potential cause of pneumoconiosis. To evaluate lung disorders among workers exposed to this dust, a cross-sectional study was carried out on 1709 workers (788 men, 921 women) in 80 factories. Data were collected by means of questionnaires, medical examinations including a chest X-ray and lung function tests and total and respirable dust measurements. Tatami mat workers were found to be at high risk for pneumoconiosis, with a dose-response relationship between dust levels and the prevalence of pneumoconiosis. A similar relationship between the prevalence of cough and sputum and the length of employment was found for non-smoking workers but not for smoking workers. Other findings are discussed.

Hypersensitivity pneumonitis in a hardwood processing plant related to heavy mold exposure
Two workers employed in a hardwood floor plant presented symptoms of hypersensitivity pneumonitis (HP). At that plant, kiln-dried wood often showed mouldy growth and was subsequently brought inside for processing. This study evaluated the environment to identify the causative agent and to verify whether other workers of this and similar plants were at risk of developing HP. Dust from dust-removing systems and moulds on the surface of wood planks were collected and air samples taken from the plant under investigation and from a sister plant. Blood samples, spirometry measurements and symptoms' questionnaires were obtained from 11 co-workers. Dense Paecilomyces growth was observed on the surface of the dried processed wood in the plant under investigation, but not at the sister plant. An additional worker had symptoms suggestive of HP, and his bronchoalveolar lavage revealed a lymphocytic alveolitis. The three confirmed cases of HP and the other 10 workers had positive specific IgG antibodies to Paecilomyces.

Influence of source directivity on noise exposure in industrial workshops
Influence de la directivité des sources bruyantes sur l'exposition sonore dans les locaux industriels [in French]
In this study, measurements were made of the directivity of noise emitted by three types of woodworking machines using a simplified acoustic intensity method enabling quick determinations to be made inside workshops. These measurements showed that the directivity of the machines studied was relatively low. Next, the influence of the directivity of these noisy machines on the exposure of workers was evaluated in a woodworking shop. Simulations showed that characteristics of the premises had little influence on noise source variability as a function of source directivity. The key factors influencing exposure were the position of the worker and his or her distance from the machine.

Sawmills - Dust during primary woodworking
Scieries - Des poussières de première transformation [in French]
Effective 1st July 2005, the occupational exposure limit for wood dust in France has been set at 1mg/m3 of air. Following a series of measurements conducted in sawmills by the Wood and Furniture Technical Centre (CTBA), it was found that this threshold was exceeded in one quarter of the cases. Various recommendations were made following these findings, concerning in particular cleaning, local and general exhaust ventilation, layout of the premises, the installation of booths and the use of personal protective equipment.

Management commitment to safety as organizational support: Relationships with non-safety outcomes in wood manufacturing employees
Employee outcomes critical to the effective functioning of an organization, including job satisfaction and commitment to the organization, were included in surveys of 641 workers at three wood products manufacturing sites. Participants were asked about perceptions of management commitment to safety and job-related variables such as perceived dangerousness of their position, organizational culture and withdrawal behaviours. Supervisors also rated the safety performance of each of their subordinates. Results suggest that employee outcomes differ based on perceptions of management's commitment to safety. Specifically, management commitment to safety was related to job satisfaction, organizational culture and job-related performance, while a negative relationship was found between commitment to safety and employee withdrawal behaviours.

Work-related disorders of the upper limb in female workers using orbital sanders
This case-control study of the prevalence of vascular, neurological and musculoskeletal disorders of the upper limb involved a group of 100 women performing either mechanical or hand sanding in the furniture industry and a control group of 100 female office workers. All participants underwent a medical interview and a complete physical investigation. There was no significant difference in the prevalence of Raynaud's phenomenon between the furniture workers and the controls, while the prevalence of carpal tunnel syndrome (CTS), peripheral sensorineural disturbances and upper-limb musculoskeletal complaints was significantly greater in the furniture workers. A CTS was clinically diagnosed in 19% of the furniture workers and 8% of the controls. Findings suggest a significant association between occupational use of vibratory tools and soft-tissue disorders in the upper limbs of female workers.
