Risk of interference. Cleaning trains: Choose the right track
Risque d'interférence. Nettoyage des trains: choisir la bonne voie [in French]
A study in the first half of 1995 analyzed the risks of occupational accidents connected with interference between the cleaning of rolling stock and other railway operations. An important conclusion was that the introduction of a safety plan can be the occasion for changes of attitude on the part of railway operators and external enterprises in favour of closer collaboration.

The occurrence and course of skin symptoms on the hands among female cleaners
Skin symptoms on the hands were studied in questionnaire-based studies conducted in 1989 and 1991 among female cleaning personnel employed at Danish nursing homes, schools and offices. A total of 1,166 participated in 1989, and 1,011 of them participated in 1991. The average age was 45 years and the average length of seniority was 10 years. One-fifth of the cleaners reported problems with cleaning agents. A total of 81% had wet hands for more than one-quarter of their working hours and 43% reported having at least one out of four skin symptoms during a one-year period. Among them, 70% reported improvement during weekends and holidays. A positive correlation was found between hours per week spent with wet hands and skin symptoms. During the follow up period, the risk of developing skin symptoms was higher among the women who remained cleaners than among those who left their cleaning jobs. Accordingly, the prognosis was better in the group that left their cleaning jobs. Retirement occurred more often among cleaners with skin symptoms than among the others. There is a future need to develop new work organization and cleaning methods to reduce the time spent with wet hands.

Cleaning, laundries and dry cleaning
Rengøringsvirksomheder, vaskerier og renserier [in Danish]
A systematic summary of publications and documentation regarding working environment factors and the state of workers' health in the cleaning, laundry and dry cleaning sectors in Denmark. This sector can be divided into cleaning, which is the main part, and other areas which include window-cleaning, chimney-sweeping, disinfection and pest control and laundries. Cleaning also includes cleaning carried out in other industrial sectors. The main working environment problems are: strain injuries, skin diseases and psychological stress. Other problems are respiratory diseases and accidents. There also seems to be an excess risk of complications of pregnancy. In smaller areas within this sector there are special problems: in laundries there are more cases of hearing damage, monotonous work and early retirement; in dry cleaning exposure to chemicals is higher and liver cancer and brain injuries are more common; chimney-sweepers are exposed to chemicals and have a higher risk of contracting cancer, non-allergic respiratory diseases and ischaemic heart disease.

Survey of cleaning workers
Enquête sur les ouvriers nettoyeurs [in French]
The present study responds to the lack of systematic surveys in France of the living and working conditions of workers employed by enterprises that clean commercial premises. A group of 924 workers in the Ile-de-France (Paris) region was followed for a year by the physicians of an inter-enterprise medical service. Social (background, status, living conditions, etc.), occupational (job titles, operations, etc.) and medical data on the individuals were collected. The medical data bore especially on occupational accidents, skin diseases and problems of bones and joints.

Exposures while applying commercial disinfectants
Exposure to disinfectants was assessed for 40 workers using various methods of application in different occupational settings. Exposure estimates for each type of application are tabulated. The primary route of exposure was by skin deposition; airborne levels were low. Dermal dose rates for aerosol spray, wipe and mop applications were low compared with liquid pour and pump methods, but longer application times for wipe and mop methods resulted in higher total doses. High-pressure sprayers received the highest exposure outside their clothing, but heavy protective clothing reduced dermal dose rates. Low-pressure sprayers with no protective clothing had the highest dose rates.

Acute changes in the EEG of workers exposed to mixtures of organic solvents
Electroencephalogram (EEG) recordings were made of 11 workers before and after exposure to mixtures of organic solvents during the cleaning of printing rolls. Inhalation exposure was quantified by personal air sampling and was considered to be low to moderate. Results indicated that even a relatively short exposure to certain mixtures of organic solvents may cause acute changes in the EEG.

Environmental and biological monitoring of occupational exposure to 1,1,1-trichloroethane
A study of 50 workers involved in various degreasing and cleaning processes using 1,1,1-trichloroethane (1,1,1-TCE) showed that open/manual degreasing processes generated the highest environmental solvent levels, followed by jet-spray cleaning, vapour degreasing and ultrasonic degreasing. Personal exposure levels were well correlated with concentrations of 1,1,1-TCE in end-of-shift expired air and venous blood samples, but only moderately correlated with concentrations of its metabolites in urine. Static (area) samples were poorly correlated with the biological exposure indices studied.

Guideline for clean-up after a fire
Leitlinie zur Brandschadensanierung [in German]
For clean-up after a fire, this recommendation from the German insurance industry defines four hazard classes. Small fires are classified as hazard class 0. Fires in kitchens, offices or workshops belong to hazard class 1. Fires involving larger amounts of plastics such as polyvinyl chloride belong to class 2. Fires in which polychlorinated biphenyls are produced (such as transformer fires) belong to hazard class 3. For fires belonging to hazard classes 2 and 3, clean-up firms with special know how need to be employed. The temperatures and conditions of a fire which lead to the development of harmful substances such as hydrogen chloride, hydrogen bromide, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, dibenzodioxins and dibenzofurans are given.

Investigation of the health risk involved in cleaning work
Untersuchung tätigkeitsspezifischer Gesundheitsrisiken im Reinigungsgewerbe [in German]
Statistical data on the types of accidents and occupational diseases among cleaning personnel were evaluated to determine the accident and health risks of this trade. In addition, data from periodic medical examinations by industrial physicians and a questionnaire survey of 645 cleaners were used. All cleaners, including bottle washers and metal cleaners, were included in the study. The most frequent causes of accidents were slipping, falls on the level and among glass and window cleaners falls from heights. Among occupational diseases skin diseases, mainly skin allergies and eczema, were most frequent. Infectious diseases, mostly hepatitis B, ranked second in frequency.

Impact of regular relaxation training and psychosocial working factors on neck-shoulder tension and absenteeism in hospital cleaners
Occupational stress in hospital cleaners and the effect of relaxation training were studied by recording the electrical activity of the upper trapezius muscle at rest and during working conditions, at the beginning, middle, and end of a six-month follow-up period. Intercorrelations were found between the neck-shoulder tension, psychosocial factors, depression, and the absenteeism rate. Relaxation training diminished tension in the neck-shoulder region efficiently; nevertheless, the decrease in absenteeism might have been related mainly to the social support offered by the research project itself.

High-efficiency particulate air/charcoal filtered vacuum cleaner challenge tests with semiconductor gases and vapors
High-efficiency particulate air (HEPA) filtered vacuum cleaners have been used for years to clean up toxic particles. Equipped with activated impregnated charcoal, vacuum cleaners have also been used to adsorb toxic vapours such as mercury. The purpose of the tests was to determine a number of parameters relating to the use of special impregnated activated charcoal for removing semi-conductor gases and vapours from the air discharge of a modified off-the-shelf HEPA-filtered vacuum cleaner. Test results were used to determine collection efficiencies as well as studying off-gassing and vapour desorption of challenge materials thought to be present during routine maintenance and servicing of semi-conductor process equipment. Such a modified vacuum cleaner can be effective in scrubbing certain semi-conductor process emissions and can enhance safety during equipment cleaning and servicing.

A chart of exposure to organic solvents in small and medium sized firms
Cartographie de l'exposition aux solvants organiques dans les P.M.E. [in French]
In order to assess the occupational hazards resulting from exposure to solvents and to adapt medical surveillance, nine occupational physicians developed a comprehensive chart containing information on the solvents used in 20 companies (4,772 employees). The methodology included a detailed inventory of the chemicals, and an assessment of the exposure according to a rough classification scale taking into account the frequency of the exposure and the degree of protection. It was possible to analyse the exposure of 827 employees (including 802 multi-exposed persons) in terms of degree of exposure and the average number of the chemicals used. Occupations where workers were least aware of the risks and were least protected were those involving gluing, cleaning and maintenance. The risk to the skin is the least known and the most neglected. Based on these data, an information sheet was drawn up for employees.

Health effects of tank cleaners
The objective of the cross-sectional study was to investigate exposure, occurrence of acute intoxication, and other health effects caused by the complex environment of tank cleaning, particularly in tanks containing different petroleum fractions. A total of 29 tank cleaners and 31 controls participated in the study. Addition of light fuel oil to facilitate the cleaning of tanks containing viscous, heavy fuel oils resulted in total airborne hydrocarbon (HC) levels of 1000-1500mg/m3. High levels of HC were measured in tanks with low-boiling petroleum fractions (naphtha and light fuel oils) of 1000-2600mg/m3 (maximum). The study reports patterns of respirator and protective equipment use. Measurements of heart rate showed that tank cleaning is, at times, a highly strenuous job. No differences between tank cleaners and controls were found with respect to spirometry, liver enzymes, or frequency of micronuclei. Acute intoxications were not frequently reported.

Maternal occupational exposure and congenital malformations
A case-referent study was conducted to assess the risk of congenital malformations in relation to maternal occupational exposure before and during pregnancy. 325 cases of major malformations and 325 normal referents identified in 15 maternity hospitals were included in the study. The results suggested that mothers of the case children with oral clefts were more often exposed to solvents during pregnancy (odds ratio, OR 7,9, 90% confidence internal, CI, 1,8-44,9) and worked more often as cleaners. Digestive anomalies (OR 11,9; 90% CI 2,0-14,9) and multiple anomalies (OR 4,5; 90% CI 1,4-16,9) were also associated with occupational exposure to solvents at work. These results were not modified when differences in maternal age, area of residence, and socioeconomic status were taken into account.

Asbestos contamination of abatement equipment surfaces
This article describes a study of the levels of asbestos fibre contamination of asbestos abatement equipment (including respirators, ladders, and hoses) found throughout the course of abatement projects. A total of 244 samples were collected from the equipment of 13 different work crews. Through surface (strip tape) sampling methods, 10 of 13 (77%) work crews arriving for work were found to have friable asbestos contamination on their equipment and/or did not maintain their equipment or load-out properly during the project. An innovative, practical method is presented to measure the effectiveness of the work crew's procedures for cleaning friable asbestos materials from equipment after the previous abatement job and the effectiveness of their load-out procedures during the current project.

Increase in non-specific bronchial responsiveness following occupational exposure to vanadium
Aumento della reattività bronchiale aspecifica dopo esposizione professionale a vanadio [in Italian]
A study was conducted to evaluate the level of bronchial responsiveness among workers recently exposed to vanadium pentoxide during periodical removal of ashes and clinker from the boilers of an oil-fired power station. A total of 11 male workers and 14 controls were examined 40-60h after the last exposure. None of the subjects in the 2 groups had symptoms of bronchial inflammation or significant airway obstruction. However, bronchial responsiveness, investigated using a methacholine challenge test, was significantly higher in the exposed group. It is suggested that exposure to vanadium increases bronchial responsiveness even without clinical appearance of bronchial symptoms. The possible role of such an increased level of airway responsiveness in the development of chronic obstructive lung disease is discussed.

Occupational skin disease in hospital cleaning and kitchen workers
Skin disorders were reported in 33% of catering staff and 35% of women cleaners who returned a questionnaire, and were employed in a large hospital. Hand dermatitis occurred in 15% of the caterers and 12% of the cleaners. In the majority, the dermatitis was irritant in origin and related to their wet work occupations. Cleaners had a high prevalence of jewellery dermatitis. Limited patch testing revealed a majority positive to nickel, but a third were negative, indicating that jewellery reactions often but not invariably predict nickel sensitivity. Few subjects were atopic, but some psoriatic patients with hand problems were encountered. Most workers were able to carry on in their occupations despite having hand dermatitis.

Impaired odor perception in tank cleaners
The olfactory perception of 20 tank cleaners exposed to petroleum products was estimated. Office workers and watchmen were used as referents (N = 20 + 20). Odour detection thresholds and the perceived odour intensity of 4 odorous stimuli, pyridine, dimethyl disulfide (DMDS), n-butanol, and heating oil vapour (gas phase of heating oil heated to + 40°C) were determined. The tank cleaners had higher absolute odour thresholds for n-butanol and oil vapour than the referents. The psychophysical function of the tank cleaners and referents differed for all the tested substances in respect to odour intensity. The tank cleaners displayed normal perception of strong stimuli but impaired perception of weak stimuli. This odour deficit was therefore named "odour intensity recruitment" and seems, in tank cleners, to be associated with exposure to oil vapour.

Occupational hand dermatoses in hospital cleaning personnel
Hospital cleaning personnel were examined for occupational dermatoses; 356 persons were included in the study. Their ages were 20-63 years with a mean of 40.1 years. The period prevalence rate of moderate and severe eczema was 12% (10% in men and 19% in women). In 88%, the eczema was of a duration longer than 2 years. Positive patch tests were found in 10% of men and 53% of women with eczema. The main allergens were nickel, cobalt, chromate and rubber chemicals. Positive tests to cleaning agents were rare. One case of contact allergy to sodium dichloroisocyanurate and one to Lysol were diagnosed. Irritant factors played a major role in most cases (92%). Fungus infection as a cause or complication in hand eczema should not be left out of consideration: in 2 persons, a mycosis of hands and/or fingernails was diagnosed.

Contact sensitivity and urticaria in "wet" work
A group of 142 hospital workers with current hand eczema was identified among 2452 recently employed persons surveyed; 91% were female. Atopy, metal dermatitis and a prior history of hand eczema were more common in the smaller group than in the larger one. Trivial irritant factors were claimed to have elicited the current episodes of eczema in 92.3% of the cases. In 35%, much of the exposure to irritant factors took place at home or during leisure time. Nickel and/or cobalt allergy were found in 1/2 of the patients with allergies. Positive prick tests for contact urticaria were found in 22 patients, and were obtained most often with foods or rubber gloves. Contact sensitivity and contact urticaria thus seem to be much less important causes of hand eczema in this group than are endogenous factors and trivial irritants (water, disinfectants and cleansers, gloves).

Atopy, occupation and domestic work as risk factors for hand eczema in hospital workers
Questionnaire and interview study of 2452 newly employed hospital workers, with follow-up over 20 months. Atopic dermatitis increased the odds of developing hand eczema by 3 times, and was correlated with greater severity of the eczema. "Wet" hospital work increased the odds by a factor of 2 compared with office ("dry") work. Two domestic factors (care of children under 4 years of age and absence of a dish-washing machine) also increased the risk of eczema; in combination with wet jobs at work, the factors increased the odds by a factor of 4. Although eczema was more common in women than in men, this is probably due to differences in the tasks performed by the 2 sexes.

Contact dermatitis to Butin-2-diol 1,4
A 41-year-old female cleaner developped dermatitis on the face, hands and forearms after having used a new cleaning agent for a few months. The dermatitis appeared about 12h after contact with the agent and settled when she was not using it. Patch testing with the components of the cleaning agent produced a strong reaction to 2-butyne-1,4-diol ("Butin-2-diol 1,4"). The compound was present in the cleaning agent at low concentration (0.7%) as a corrosion inhibitor.

Occupational dermatoses in hospital cleaning women
In an investigation of 541 members of a hospital cleaning department, a prevalence rate of occupational disease of 15.3% was found. 39.1% of those surveyed had a skin disease at one time or another during their hospital employment. An observed higher prevalence in the younger age groups can be explained by the selection of those with skin diseases for work away from the cleaning department. Many persons developed their disease shortly after employment began, which indicated that most conditions were irritant diseases. This was confirmed by diagnosis: 75% of the conditions were irritant dermatitis (formaldehyde, glutaraldehyde, chloramine, nickel, rubber), 21% were allergic contact dermatitis (detergents, alkaline substances, acids, sodium perborate, hypochlorite and hypobromite compounds), and 4% were monilia of the finger webs. Causes of irritant dermatitis were detergents, alkaline substances, acids, sodium perborate, and hypochlorite-hypobromite combinations. The problems can be alleviated by prophylactic measures.

Case study. Exposure to vanadium pentoxide
8 men who had been maintaining a very large oil-fired boiler for a few weeks suffered acute respiratory and other symptoms. The crude oil used contained a small amount of vanadium as an impurity. Work was done inside the boiler and in the deadspace at the top. The workers inside the boiler were in close contact with scale contaminated by condensed vanadium pentoxide. Samples of scale from 3 areas inside the boiler contained 14.2, 10, and 5.8% vanadium pentoxide. There were no residual health effects. Protective clothing had not been worn. Recommendations are made concerning: pre-employment and other medical examinations; selection of breathing and eye protection; general protective clothing; biological monitoring of urine samples; dust measurement. The literature is reviewed.

Workers employed in cleaning and disinfecting: environmental risk factors, pathology, prevention
Addetti a lavori di pulizia e disinfezione: fattori di rischio ambientale, patologia, note di prevenzione [in Italian]
Among the risks affecting cleaners are: high humidity, extremes of temperature; use of hazardous substances (natural soaps, synthetic detergents, acids, waxes, disinfectants); bent-over work posture; repetitive and high-stress work. The resulting health problems are: skin problems (dermatitis, skin allergies); mucous membrane irritations; back and joint pain; nervous problems (chronic fatigue, sleep disturbances, headaches); accidents (slips, falls from heights, electric shocks). Preventive measures suggested: careful selection of chemical products; accurate labelling; avoidance of small/badly ventilated rooms after the use of hazardous substances; forbidding of dangerous practices (e.g. use of certain cleaning substances at high concentrations); avoidance of skin contact with the substances used (wearing of gloves); regular medical examinations and vaccination against tetanus and typhoid fever.

Vanadium exposure in cleaners of oil burning boilers: possibility of biological monitoring
Esposizione a vanadio nei pulitori di caldaie per olio combustibile: possibilità di monitoraggio biologico [in Italian]
Vanadium exposure is related to vanadium concentration in the urine and hair of workers. Vanadium levels in the combustion residues were 2-12%, in the urine of heavily exposed workers 57±16µg/l, in the urine of lightly exposed workers 7.8±6.2µg/l, in the urine of controls 1.8±0.2µg/l. Measurements in hair, though statistically significant, could not be related to different urine concentrations, or to length of exposure.

Exposure of nickel and the relevance of nickel sensitivity among hospital cleaners
Review of reports on nickel sensitivity and nickel hand eczema in hospital cleaning workers and report of studies on cleaning water in 5 hospital in-patient units to determine whether this water contained the nickel sensitising agent. Analysis of the fresh water and of the water after various hospital appliances and installations had been washed. Statistically significant increases of the nickel concentrations were found at each step of the cleaning, eventually exceeding the theoretical sensitising safety limit. It is thought that a significant amount of this nickel is released during the cleaning of stainless steel appliances and installations. Nickel penetrates rubber gloves and therefore the wearing of vinyl gloves is recommended.
