Burns due to explosions of various types of inflammable dust have been reported, including coal dust, flour and grain dust. A 33-year-old worker was burned over 33 per cent of his body surface area in a sawdust explosion. Recovery was uneventful. This is the first reported case due to this mechanism as far as we have been able to ascertain.

A new experimental setup was developed to expose pigs to dust and airborne endotoxins in an environmental chamber, at levels liable to be encountered in pig farm buildings. The following parameters were evaluated in a chamber containing two pigs of 10 kg body-weight: inhalable and respirable dust gravimetric concentrations were measured using area samplers and expressed as mg/m3. The respirable...

OBJECTIVES To explore relations between two estimates of exposure to inhalable flour dust, and the incidence rates (IRs) of asthma and rhinitis in bakers. METHODS This was a retrospective cohort study among 2923 bakers. A posted questionnaire registered the disease and work history. For every year, each baker was assigned an estimate of the exposure concentration to inhalable flour dust deriv...

The purpose of the study was to determine the prevalence and causation of work-related asthmatic symptoms in a population exposed to grain, flour and other ingredient dusts. Where workers complained of asthmatic symptoms which were the result of dust exposure, follow-up aimed to identify whether the symptoms were the result of sensitisation or of non-specific irritation. A questionnaire was pre...

OBJECTIVE To investigate whether interventions implemented by the UK Health and Safety Executive addressing exposure to isocyanate-based spray paints in motor vehicle repair (MVR), flour dust in craft bakeries, rosin-based solder flux fume (RBSFF) in the electronics industry, metalworking fluids and wood dust coincided with a decline in incidence of work-related short latency respiratory diseas...

Findings are presented from the initial cross sectional phase of a cohort study of employees exposed to flour in bakeries or mills. Of 401 eligible workers in seven sites 344 (86%) were surveyed; symptoms assessed by self completed questionnaire, and sensitisation measured by the response to skin prick tests, were related to intensity of exposure both to total dust and to flour aeroallergen. Am...

The purpose of this study was to estimate the risk of adult asthma in relation to certain occupational exposures. The study was designed as a case-control study in Göteborg, including 321 subjects with asthma, born between 1926 and 1970. Controls (n=1,459) were randomly selected from the same area from registers of the 1986 population. Questionnaire information was collected in 1996, and includ...

Introduction: Exposure to flour dust is an important risk factor in occurrence of allergic airway disorders among mill workers. The purpose of this study was to determine the prevalence of respiratory symptoms and its relation with exposure to respirable dust. Materials and Methods: In this study, all of 35 workers who worked in the flour producing section of three factories were chosen as ca...

Asthma caused by allergy to proteins from cereal grains is one of the most common types of occupational asthma (OA) worldwide and its prevalence does not appear to be declining. Baker’s asthma is the most serious manifestation of occupational allergy among bakery workers, which develops after inhalational exposure to flour dust allergens encountered in the work environment. Exposure to cereal f...
