Survey of dermal protection in Washington State collision repair industry
This study investigated the personal and workplace factors associated with painters' dermal protection use during a large-scale exposure assessment. Survey data indicated that 69% of painters always used gloves, with latex gloves and nitrile gloves used most frequently. Among latex glove users, 53% used thin latex, 6% used medium latex and 12% used thick latex. Among nitrile glove users, 27% used thin nitrile and 45% used medium nitrile. Sixty-three percent of painters always used coveralls, 44% preferring one particular brand. Although overspray presents an opportunity for dermal exposure to the neck and face, only 19% of painters protected these areas with personal protective equipment. Exact logistic regressions along with random sample calculations indicated that the survey results were independent of the shops. Other findings are discussed.

Effects of wearing the wrong glove size on shoulder and forearm muscle activities during simulated assembly work
This study was performed to determine the changes in electromyography activity in the shoulder and forearm muscles when using the bare hands, well-fitting gloves and gloves that are one size smaller or one size larger for simulated assembly operations. Sixteen asymptomatic seated workers with normal hands and no obvious deformities, skin diseases, or allergies were recruited and were asked to simulate assembly operations. It was found that wearing the wrong glove size led to a decrease in forceful activation of the forearm muscle and a compensatory increase in shoulder movement. In contrast, use of the bare hands or wearing well-fitting gloves led to effective forearm muscle activation, which decreased inefficient shoulder movement. These data indicate that wearing the wrong glove size will lead to continuous inefficient use of the forearm and shoulder muscles, and result in overuse of the shoulder.

Barrierity of hydrogenated butadiene-acrylonitrile rubber and butyl rubber after exposure to organic solvents
Resistance of chemical protective clothing primarily depends on its constituent materials, in particular on the type of polymer used for coating the fabric carrier. This article reports on systematic investigations on the influence of the cross-linking density of an elastomer and the composition of a cross-linked elastomer on its resistance to permeation of selected organic solvents. Tests of barrier material samples made from nonpolar butyl rubber (IIR) and polar hydrogenated butadiene-acrylonitrile rubber (HNBR) showed that in rubber-solvent systems with medium thermodynamic affinity, cross-linking density influenced resistance to permeation and the polarity of the system had a significant influence on the barrier properties.

Practices in pesticide handling and the use of personal protective equipment in Mexican agricultural workers
In this study, information was collected by means of questionnaires from 99 Mexican agricultural workers (35 women and 64 men) concerning sociodemographic data, agricultural practices, use of pesticides, use of personal protective equipment (PPE) and risk perception. As expected, men handled pesticides more frequently than women (67% versus 20%). The workers carried out several agricultural tasks, used a great number of pesticide products (59 commercial brands of pesticides, 33 active ingredients, and 20 chemical families), used mostly manual application equipment, and showed a low rate of correct usage of PPE (2%) and insufficient levels of proper hygienic practices. In addition, storage of pesticide products and application equipment at home was frequent among this group of workers (42%), and provides a significant source of exposure for the workers' families. Implications of these findings are discussed.

Physiological strains of wearing aluminized and non-aluminized firefighters' protective clothing during exercise in radiant heat
This study examined the influences of aluminized and non-aluminized firefighters' protective clothing on physiological and subjective responses in radiant heat. Eight firefighters performed exercise at an air temperature of 30°C with 50%RH. Three bouts of 10 min-bicycle exercise in radiant heat (a globe temperature of 70°C) were spaced by a 10 min rest with no radiant heat. Results showed that rectal temperature, mean skin temperature, heart rate, and body weight loss were significantly greater for the aluminized clothing than for all types of non-aluminized clothing. For the aluminized clothing, thermal gradient of the body reached 0.0 ± 0.7°C, heart rate showed a maximum level of 183 ± 11 bpm and 1.9% of body weight was lost due to sweat secretion. Firefighters felt the hottest and most discomfort in the aluminized clothing. It appeared that firefighters' thermoregulatory mechanism was severely challenged by wearing aluminized protective clothing during exercise in strong radiant heat. Therefore, it is suggested that the safe upper limits while wearing aluminized firefighters' clothing should be distinguished from those for typical firefighters' protective clothing.

The efforts in the forearm during the use of anti-vibration gloves in simulated work tasks
The objective of this study was to analyze the levels of forearm muscular contraction associated with the use of anti-vibration gloves. Two vibrating tools (multi-cutter and rotary hammer) were used in a simulated work environment. Standard operations were performed by each of the 14 subjects using the two tools. Forearm muscular efforts were measured by surface electromyography (EMG) in four muscles: flexor digitorum superficialis (FDS), flexor carpi ulnaris (FCU), extensor carpi radialis longus (ECRL) and extensor carpi ulnaris (ECU). For the flexor muscles (FDS and FCU), a decrease tendency in the measured EMG was observed when the operations are performed with gloves relative to the bare hand (a reduction of 5-23% in the percentage of maximum voluntary exertion (%MVE)). For the extensor muscles (ECU), a tendency toward increased muscular contraction was observed when the operations were performed with gloves (an increase of 3-20% in the %MVE). No such tendency was found in the ECRL muscle. It is concluded that anti-vibration gloves may increase forearm fatigue in the posterior forearm (ECU muscle) and decrease forearm fatigue in the FDS muscle during operations with the vibrating tools.

Effect of contaminants on the mechanical resistance of protective gloves - Preliminary analysis
Effet des contaminants sur la résistance mécanique des gants de protection - Analyse préliminaire [en francés]
In many industrial sectors, workers use protective gloves against mechanical hazards in the presence of contaminants such as oils or greases. Such contamination can, however, reduce the resistance of the gloves to mechanical hazards. This study was undertaken to evaluate the extent of this phenomenon on cut, puncture and tear resistance properties of a range of gloves after their contact with a series of industrial contaminants and to compare the results to measured values on new gloves. It also examines the effects of glove washing. Findings are discussed. The collected data will be incorporated into a protective glove selection guide currently being developed, which users can consult on the IRSST's web site.

Evaluation of the filtration performance of NIOSH-approved N95 filtering facepiece respirators by photometric and number-based test methods
N95 particulate filtering facepiece respirators are certified by measuring penetration levels photometrically with a presumed severe case test method using charge neutralized NaCl aerosols at 85L/min. However, penetration values obtained by photometric methods have not been compared with count-based methods using contemporary respirators composed of electrostatic filter media and challenged with both generated and ambient aerosols. To understand the effects of particle charge and detection methods, penetration levels for five filtering facepiece respirators were measured using NaCl aerosols with the aerosol challenge and test equipment employed in the NIOSH respirator certification method, and compared with an ultrafine condensation particle counter method. Findings are discussed.

Evaluation of nano- and submicron particle penetration through ten nonwoven fabrics using a wind-driven approach
This study focused on the design and characterization of a method for evaluating the performance of materials used in protective clothing. Ten nonwoven fabrics were selected, and physical properties including fiber diameter, fabric thickness, air permeability, porosity, pore volume and pore size were determined. Each fabric was sealed flat across the wide opening of a cone-shaped penetration cell that was then housed in a recirculation aerosol wind tunnel. The flow rate naturally driven by wind through the fabric was measured, and the sampling flow rate of the Scanning Mobility Particle Sizer used to measure the downstream particle size distribution and concentrations was then adjusted to minimize filtration effects. Results show that particle penetration increased with increasing face velocity, and penetration also increased with increasing particle size up to about 300 to 500nm. Penetrations measured by the wind-driven method were lower than those obtained with the filtration method for most of the fabrics selected, and the relative penetration performances of the fabrics were very different due to the vastly different pore structures.

Particle release from respirators, Part II: Determination of the effect of tension applied in simulation of removal
This study evaluated the potential for disposable filtering facepiece respirators (hereafter termed masks) contaminated with 1μm particles to release particles as a result of lateral tension applied to the mask. The lateral tension was designed to simulate the removal of a contaminated mask from a user's head. Four brands of filtering facepieces were loaded with approximately 20 million 1.0μm polystyrene latex microspheres. The respirators were then placed in a test chamber and subjected to lateral tension between 17.8-26.7 for 1-2sec. Findings suggest that neither mask type nor loading condition affects particle release. This supports the hypothesis that when filtering facepiece respirators are properly removed from the head they will not release a significant number of particles. See also ISN 111322.

Particle release from respirators, Part I: Determination of the effect of particle size, drop height, and load
In late 2001, some United States Postal Service workers and a few members of Congress were exposed to anthrax spores. This led to an increased effort to develop employable methods to protect workers from exposure to anthrax. This study evaluated the potential for several types of half-mask respirators to release deposited particles. Four brands of the most commonly used filtering facepiece respirators were loaded with 0.59μm, 1.0μm, and 1.9μm polystyrene latex microspheres and then dropped onto a rigid surface. The load conditions were 10, 20, or 40 million particles, and drop heights were 0.15, 0.76 and 1.37 m. Results of these tests were inconclusive. Part II (see ISN 111323) addresses the release of particles when simulating removal of a filtering facepiece from a wearer's head.

Elastomeric, half-facepiece, air-purifying respirator performance in a lead battery plant
This workplace protection factor (WPF) study of a half facepiece air-purifying respirator with P100 filters was done in a lead battery manufacturing plant. Paired air samples for lead were collected inside and outside respirators worn by workers who were properly trained and quantitatively fit tested. Of the 45 valid sample sets, only four had detectable lead on the inside sample. WPFs were calculated for these sample pairs by dividing the outside sample lead concentration (C(o)) by the inside concentration (C(i)). For the remaining 41 sample pairs, the detection limit for lead was used to calculate a maximum estimated C(i) concentration. The C(o) for each of these sample pairs was divided by the C(i) estimate to obtain a minimum WPF value. All the WPFs were rounded down to two significant figures, resulting in values ranging from 12 to over 2500. A rank and percentile procedure resulted in a 50th percentile WPF of 270 and a lower 5th percentile estimate of above 50. These WPFs exceed the assigned protection factor of 10 for half facepieces published by the Occupational Safety and Health Administration. Implications of these findings are discussed.

Study of sound transmission through hearing protectors and application of a method for evaluating their efficiency in the workplace - Part 1 - Field study (revised version)
Etude de la transmission sonore à travers les protecteurs auditifs et application d'une méthode pour évaluer leur efficacité en milieu de travail - Partie 1 - Etude terrain (version révisée) [en francés]
The method for evaluating the noise attenuation characteristics of hearing protectors is based on laboratory tests. However, many studies have shown that the actual effectiveness of this protective equipment is, more often than not, much lower than the results thus obtained. This study examined the time evolution of the performance of this equipment during one work shift, with 24 workers, in different sound environments, in Quebec, Canada. This mainly enabled them to develop a method for measuring the real effectiveness of earmuffs and moulded ear plugs, and then to compare it to measurements taken in the laboratory. Findings show protection values lower than those documented by the manufacturers (measured in the laboratory); for a given worker, the protection varies significantly in relation to the time during a work shift; the protection can vary greatly from one worker to the next but also from one ear to the other for a given worker. The developed attenuation index shows a high dependency on the frequency spectra of the ambient noise, thus highlighting the inadequacy of some hearing protectors at low frequencies and the importance of properly understanding the ambient noise so that a judicious choice of hearing protectors can be made.

Why don't pesticide applicators protect themselves? Exploring the use of personal protective equipment among Colombian smallholders
The misuse of personal protective equipment (PPE) during pesticide application was investigated among smallholders in Colombia. Findings suggest that the descriptive social norm was significantly influencing PPE use. The following were also important: having experienced pesticide-related health problems; age; the share of pesticide application carried out; the perception of PPE hindering work. Interestingly, the influence of these factors differed for different pieces of PPE. Since conformity to the social norm is a source of rigidity in the system, behavioural change may take the form of a discontinuous transition. Suggestions for triggering a transition towards more sustainable PPE use are formulated.

The life-saving effectiveness of body armor for police officers
The objective of this study was to determine the effect of protective body armour on a police officer's risk of being killed and estimate the benefits and costs of outfitting police with body armour. In the United States, for the 262 cases of police being shot in the torso from 2004 to 2007, the study calculates the relative risk of death from a gunshot without and with body armour. The benefit of body armour is estimated using the willingness-to-pay approach and compares it with the cost of supplying armour to police not currently wearing armour. The results show that the relative risk of dying without armour is 3.4. Outfitting all police with armour would save at least 8.5 lives per year, resulting in a benefit that is nearly twice the cost, or a net benefit of approximately USD100/officer.

Adequacy of personal fall arrest energy absorbers in relation to heavy workers
Despite the increasing weight of workers, most energy absorbers of personal fall arrest systems are only tested to 100 kg. This research aims to evaluate the capacity of fall arrest energy absorbers in relation to the weight of heavy workers, so as to provide recommendations for improvements to current fall arrest standards. A series of dynamic drop tests based on the Australian and New Zealand fall protection equipment standard were conducted. A total of 31 samples on seven types of energy absorbers were undertaken. The experiment simulated a worst credible scenario of a 3.8 m fall of a rigid mass which was connected using inelastic material. The capacity of each type of energy absorber was determined using the test mass that caused one or both of the following test criteria to be breached: at least two samples reached the maximum possible extension and at least two samples had the maximum arrest force exceeding 7 kN. The estimated capacities were then compared with the 95th percentile weight of worker working at height. The research demonstrates that most energy absorbers are not able to ensure that the two test criteria are not breached during the arrest of a heavy worker in the worst case scenario fall. It is recommended that the test mass stipulated in fall arrest standards should be revised and increased to accommodate the increasing weight of workers.

Performance of mechanical filters and respirators for capturing nanoparticles - Limitations and future direction
There is an increasing concern about the health hazards posed to workers exposed to nanoparticles by inhalation, which is the most common route of exposure. Filtration is the simplest and most common method of aerosol control. It is widely used in mechanical ventilation and respiratory protection. However, concerns have been raised regarding the effectiveness of the filters for capturing nanoparticles. This article reviews the literature on the filtration performance of mechanical filters and respirators against nanoparticles. It discusses filtration mechanisms, theoretical models, affecting factors of the filtration efficiency and testing protocols for respirator and filter certification.

Real world use and performance of hearing protection
This report considers the effectiveness of hearing protectors in everyday work situations. The study reported here was undertaken in two parts. The first consisted of interviews with employers to discuss management of noise and hearing protector use, and on site observation of hearing protector use. The second part consisted of laboratory measurements of hearing protector insertion loss. The purpose of these measurements was to quantify the reduction in protection due to poor fitting or maintenance for a range of hearing protectors. Earmuffs were tested using the MIRE (microphone in real ear) method while earplug insertion loss was measured using a head and torso simulator with a simulated pinna and ear canal. Findings are discussed.

Performance of an N95 filtering facepiece particulate respirator and a surgical mask during human breathing: Two pathways for particle penetration
The protection level offered by filtering facepiece particulate respirators and face masks is defined by the percentage of ambient particles penetrating inside the protection device. There are two penetration pathways, through the faceseal leakage and through the filter medium. This study aimed at differentiating the contributions of these two pathways for particles in the size range of 0.03-1 μm under actual breathing conditions. One N95 filtering facepiece respirator and one surgical mask commonly used in health care environments were tested on 25 subjects (matching the latest National Institute for Occupational Safety and Health fit testing panel) as the subjects performed conventional fit test exercises. The respirator and the mask were also tested with breathing manikins that precisely mimicked the pre-recorded breathing patterns of the tested subjects. The penetration data obtained in the human subject- and manikin-based tests were compared for different particle sizes and breathing patterns. Overall, 5250 particle size- and exercise-specific penetration values were determined. For each value, the faceseal leakage-to-filter ratio was calculated to quantify the relative contributions of the two penetration pathways. The number of particles penetrating through the faceseal leakage of the tested respirator/mask far exceeded the number of those penetrating through the filter medium. Because most of the penetrated particles entered through the faceseal, the priority in respirator/mask development should be shifted from improving the efficiency of the filter medium to establishing a better fit that would eliminate or minimize faceseal leakage.

Indicators of hearing protection use: Self-report and researcher observation
This study compares workers' self-reported use of hearing protection with their observed use in three workplaces with two types of noise environments: one construction site and one fixed industry facility with a variable noise environment, and one fixed industry facility with a steady noise environment. Subjects reported their use of hearing protection on self-administered surveys and activity cards, which were validated using researcher observations. Good agreement was found overall between subjects' self-reported HPD use and researcher observations. Workers in the steady noise environment self-reported hearing protection use more accurately on the surveys than workers in variable noise environments. The findings demonstrate the potential importance of noise exposure variability as a factor influencing reporting accuracy.

Contact dermatitis caused by personal protective equipment (PPE)
Dermatites de contact aux équipements de protection individuelle (EPI) [en francés]
Occupational skin diseases caused by personal protective equipment (PPE) essentially consist of irritant and/or allergic contact dermatitis and contact urticaria. Exposed occupations depend on the type of PPE used. This information note describes the types of PPE likely to cause contact dermatitis (gloves, shoes and boots, work clothing, diving equipment) and the responsible allergens. Aetiological diagnosis is based on anamnesis, clinical examinations and allergy tests. Collective prevention should make full use all of measures likely to reduce exposure, and the substitution of latex and the most common allergens in PPEs should be implemented wherever possible. Medical prevention is based on stopping all occupational and non occupational contact with the responsible allergens.

In the line of fire - Protecting emergency services personnel from feeling the heat
Using the case of a fire having erupted in an Australian winery, this article explains the importance of protecting firefighters and volunteers not only from the fire itself, but also from the release of dangerous substances and from the high level of heat radiated by the fire. The conclusions of the investigations carried out after the fire are discussed, including the importance of carrying out regular hazard evaluations, training workers in emergency procedures, storing hazardous substances in dedicated areas and making the layout of the premises available and clearly visible to firefighting personnel.

Protection against impact with the ground using wearable airbags
This article presents three types of wearable airbag systems for protection against falls from heights, wheelchair overturns and falls on the same level. The systems consist of an airbag, sensor, inflator, and jacket. The sensor detects the fall and the airbag inflates to protect the user. Fall tests using dummies with and without the airbags demonstrated the effectiveness of these devices. In fall heights of less than 2m, the airbags reduced the impact acceleration. Head Injury Criterion values were under 1000, as per the auto-crash test requirement. The limits to the amount of protection afforded are discussed.

The use of personal protective equipment in pregnant greenhouse workers
The objective of this study was to determine the use of personal protective equipment (PPE) among pregnant greenhouse workers in Italy and to identify risk factors related to the non-use of appropriate preventive measures. A structured questionnaire was administered by trained interviewers to 232 Italian female greenhouse workers regarding their use of PPE and the outcomes of their first pregnancy. Although most pregnant women used at least one form of PPE while working, there were differences in rates of PPE use according to social status. Overall, the protection was inadequate in the south of Italy and among the less educated. Other findings are discussed.

El médico del trabajo en el control del uso de equipos de protección individual y los problemas de la salud derivados
All workers are exposed to a number of risks, most of them preventable in a collective manner, but in cases where these measures are not sufficient, the use of personal protective equipment (PPE) becomes necessary. These items are intended to be carried or worn by workers to protect them from risks that may threaten their safety or health in the workplace, but are however themselves also capable of creating their own effects on the safety and health of workers. For this reason, occupational physicians should monitor the health of workers, assessing the personal factors that might hinder the use of PPEs, inform and train workers on all matters relating to their use, choose the appropriate PPE for each worker and, above all, follow up to detect possible effects of the use of PPE, thus avoiding their nonuse.

Training and other predictors of personal protective equipment use in Australian grain farmers using pesticides
The objective of this study was to investigate patterns of use of personal protective equipment (PPE) to reduce pesticide exposure in a sample of Australian farmers and also to assess possible predictive factors. A cross-sectional survey of 1102 farmers was conducted by means of a questionnaire. Up to 40% of the farmers reported routinely using no PPE at all when exposed to pesticides. In multivariate analyses PPE use appeared to be most strongly associated with younger age and farm chemical training. Other findings are discussed.

Assessment of pesticide exposure control practices among men and women on fruit-growing farms in British Columbia
Exposure to pesticides can be reduced by wearing personal protective equipment (PPE) or by implementing alternative pest control techniques, such as Integrated Pest Management (IPM). A cross-sectional telephone survey was conducted to explore the prevalence of these practices among a total of 380 men and women involved in fruit growing in British Columbia, Canada. Among the 119 workers who applied pesticides, 63% indicated that they usually wore PPE during application. Individual equipment use varied. Gloves were worn most frequently (84%), followed by a spray suit (77%) and breathing protection (75%). Implications of these and other findings are discussed.
