- In 1989, an international project was initiated known as MEPS (Musculoskeletal, Visual, and Psychosocial Stress in VDT Operators in Optimised Environment). The aim of the MEPS project was to minimise stress amongst VDT operators by creating optimum working conditions through intervention measures at individual workstations. Professionals representing different disciplines were involved in this study to investigate possible factors causing musculoskeletal complaints, visual discomfort and psychosocial stress among VDT users. This paper describes the ergonomic part of the study including the methods that were developed and used to examine prevailing working conditions and how the data was analysed.

- Helmets are widely used in industries as a primary protection means for workers. Helmets can provide efficient protection against occupational hazards to the head, they also cause thermal discomfort to the wearers at work. To develop a reliable heat transfer testing method for helmets any objective testing method must be validated with subjective testing of the same helmets. Subjective evaluation of helmet heat transfer properties was conducted in both cold and hot conditions using three commonly used and commercially available helmets. Twenty-five subjects participated in a laboratory investigation in a simulated cold environment( + 3 degrees C and 30% RH); forty-three steel-making workers participated in a held survey in the hot environment (31 degrees C and 32% RH). Subjects were either asked to conduct certain tasks (in the laboratory investigation) or performed their regular production duties (in the filed survey) while wearing a helmet; they were then asked to answer questions in a questionnaire at the end of the surveys. The results of the subjective assessment which were compared with the objective measurements taken on a sweating manikin head using the same helmets, were found consistent.

Adverse health reactions in skin, eyes, and respiratory tract among dental personnel in Sweden

Tidskriftsartikel (refereegranskat)abstract
- Dental personnel manually handle products that contain monomers. Several studies have documented adverse health effects after exposure to such products. Gloves made of vinyl or latex are easily penetrated by monomers. Ordinary glasses, or visors, do not protect against vapour from polymer products. Dental face masks filter out about 40% of respirable particles. To survey the prevalence of asthma, atopic dermatitis, conjunctivitis, hay fever/rhinitis, and hand eczema among dental personnel, a questionnaire was distributed to all dental teams in Northern Sweden. Referents were researchers, teachers, and secretaries from the same geographical area. The response rate was 76% for dental teams, and 66% for referents. The results show a significantly higher prevalence of conjunctivitis, and atopic dermatitis among dentists, both male and female. Hypersensitivity to dental materials was reported by significantly more dental personnel than by referents.

Amalgam in dentistry : A survey of methods used at dental clinics in Norrbotten to decrease exposure to mercury vapour
- 1995

Ingår i: Swedish Dental Journal. - 0347-9994. ; 19:1-2, s. 55-64

Tidskriftsartikel (refereegranskat)abstract
- A survey was conducted on the possible factors influencing exposure to mercury vapour during the handling of amalgam and amalgam contaminated products at dental clinics in Norrbotten, the northern part of Sweden, as well as the current methods being used to minimise, if not prevent such exposures. Increased room temperature, a serious problem when working with amalgam, was the most common complaint from the dental personnel reflecting the observation that ventilation in most clinics was far from being satisfactory. However, methods of treating amalgam-contaminated waste products as well as the classification of products as high- or low-risk wastes also differed a lot. The results further showed that although majority of the dental personnel showed concern on the possible hazards of mercury vapour exposure and were interested in having the level of mercury vapour measured in their clinics, very few had access to any protective equipment against it. And among the few who had some forms of protective wear, most found the equipment disturbing and disruptive of work performance.
