Diffusion of nitrosamines through protective gloves.

A simple experimental demonstration of the permeability of protective gloves to volatile nitrosamines has been carried out. Rubber and polyvinyl chloride (PVC) gloves were turned inside out and the fingers filled with dilute solutions of nitrosamines in hexane. The outer faces of the fingers were washed with water at various times and the nitrosamine content of these washings determined. From these measurements the proportions of the various nitrosamines passing through the gloves were calculated. For both types of gloves N-nitrosopyrrolidine (NPYR) permeated the fingers most rapidly and to the greatest extent. Only a relatively small amount of N-nitrosodibutylamine (NDBA) was transmitted. It was also established that the rubber gloves themselves did not contain any of the common volatile nitrosamines; N-nitrosomethylphenylamine and N-nitrosodiphenylamine were also absent.

Penetration of protective gloves by epoxy resin.

A gas jointer developed dermatitis from epoxy resin of Bisphenol A type. This substance penetrates plastic and rubber gloves. The man was compelled to change his job. There is a need for new types of gloves which are impermeable. The wearing of the existing types of glove by those not sensitised may be worthwhile because it probably lessens the dose of allergen absorbed and hence lessens the incidence of sensitisation.

The permeability of laboratory gloves to selected nitrosamines.

Samples of laboratory gloves of various composition and thicknesses were used as barriers between 0.136 M solutions of nitrosamines (dimethyl-, ethylmethyl-, diethyl-8 n-butylmethyl-, di-n-propyl-, di-iso-propyl- and di-sec-butyl- in dichloromethane, acetone, ethanol and double-distilled, deionized water) and water. The concentration of permeated nitrosamine was measured periodically. Nearly all gloves tested were permeable to the nitrosamine solutions. The results indicate that: (1) gloves should not be assumed to provide full protection, (2) gloves should be discarded immeidately following overt contamination and (3) gloves should not be reused.

[Use of colored samples in the detection of occupational exposure to allergic effects of chromium and nickel compounds].

By using a coloured sample with diphenylcarbazide, chromium content in raw materials and industrial intermediate products was determined. At the same time chromium content was determined quantitatively by atomic absorption. The method was said to be simple and easy to be done in any industrial physician's conditions. The sample's sensitivity was said to be 1:100 000. Results of the determinations indicated that protective leather gloves contained considerable content of chromium, and chromium-free machine oils and lubricants were polluted with chromium's minute quantities as the oils and lubrications were being used. It was stated that coloured samples aiming at the detection of chromium, cobalt and nickel should be routinely used in preventive activity of industrial physicians.

Handling of highly infectious material in a clinical pathology laboratory and in a viral diagnostic unit.

The handling of potentially lethal and highly infective material in a routine clinical pathology laboratory and in a viral diagnostic unit is detailed. Extensive precautions were taken at each step of the receiving, processing and disposal cycle. Disposable protective clothing and apparatus were used whenever possible. Laboratory tests were limited to those essential for the clinical management and diagnosis. Technologists who handled infective material were limited to minimal numbers of experienced, non-pregnant, informed volunteers. They wore special protective clothing, including gloves, caps, gowns and masks. When possible, specimens were handled under special protective hoods. Potentially infective material was processed through automated apparatus, and care was taken to prevent contamination of its exterior. The effluent from the machines was collected into viricidal agents (glutaraldehyde, sodium hypochlorite). After processing, the machines were flushed extensively with viricidal solution. This procedure has caused no damage to the automated equipment and has been adopted as a routine laboratory safety measure. The protective procedures adopted were successful in that there was no outbreak of the viral infection among the associated laboratory workers.

Permeation of glove materials by physiologically harmful chemicals.

The breakthrough times and permeation rates of 1,4-dichloro-2-butene, benzene, carbon tetrachloride, and 2-chloro-1,3-butadiene for eleven commercially available gloves were determined. Four methods of determining the breakthough time and permeation rate were evaluated. A wide variation in the glove material thickness and protection time was found showing that the adequate protection time can only be determined by testing the proposed glove with the chemicals to be handled.

Laceration of the median nerve from skiing.

Increased numbers of injuries to the upper extremity are being seen since improved equipment is available to protect the lower extremity. Three patients, who are excellent skiers, have been seen in which significant structures of the wrist were lacerated by the sharp outer edge of the ski. Well fitted leather gloves or mittens designed to protect the palmar surface of the wrists are recommended during skiing. We must now focus our attention to design better protection for the more vulnerable upper extremity during the sport of skiing.

Micropunctures of rubber gloves used in oral surgery.

In 720 operations in ambulatory oral surgery, the 2,880 surgical rubber gloves used were tested at the end of operation for perforations not earlier detected (microperforations). Gloves of ordinary thickness (type A) and of a thicker quality (type B) were examined. Perforations were found in 1495% and 22.0% of type A gloves and in 3.2% and 2.0% of type B gloves when oral surgeons and dental students, respectively, were operators. Gloves worn by operation assistants showed a lower incidence of perforation. Before operation, 50 gloves of type A were punctured at the tip of right index finger by a sterile dental probe. Results of bacteriologic examinations of the right index and middle fingers strongly indicated that a high number of bacteria passed through pinholes in the gloves. The intact surgical glove represents an impermeable barrier, protecting not only the operation wound against skin bacteria from the hands of the oral surgeon, but also the oral surgeon against pathogenic microorganisms, in particular hepatitis virus type B, escaping from the oral cavity of the patient.

Enhanced barrier precautions to prevent transmission of Staphylococcus aureus and Carbapenem-resistant organisms in nursing home chronic ventilator units.

OBJECTIVE: Assess the feasibility and effect of Enhanced Barrier Precautions (EBP) on the transmission of Staphylococcus aureus (SA) and carbapenem-resistant organisms (CRO) among residents in nursing home chronic ventilator units (NH-CVU). DESIGN: Pre-post interventional study. SETTING: Two community-based nursing homes with CVUs in Maryland. A total of 56 residents were enrolled in the baseline period and 64 residents were enrolled in the intervention period. METHODS: During a 3-month baseline and intervention period, residents were swabbed monthly to estimate SA and CRO acquisition. During a 2-month training period, EBP was implemented for residents with chronic wounds, medical devices, or history of multidrug-resistant organism (MDRO) colonization. During the subsequent 3-month intervention period, healthcare personnel (HCP) wore gowns and gloves for high-contact care activities when residents were on EBP. Whole genome sequencing assessed resident-to-resident transmission. RESULTS: At baseline, NH-CVU1 used gowns and gloves for all direct contact, while NH-CVU2 used EBP only for residents with a history of MDRO colonization. After training, the proportion of NH-CVU2 residents on EBP increased from 65% in the baseline period to 87% in the intervention period. Glove use was high (93-98%) in both NH-CVUs. Gown use increased from 39% to 77% in NH-CVU1 and from 26% to 72% in NH-CVU2. Resident-to-resident transmission of SA or CRO decreased by 25% in NH-CVU1 (p = 0.60) and by 67% in NH-CVU2 (p = 0.05). CRO transmission decreased by 33% in NH-CVU1 (p = 0.54) and by 83% in NH-CVU2 (p = 0.02). CONCLUSIONS: EBP is feasible and potentially decreases overall and CRO transmission in nursing home CVUs.

Need for protective clothing and equipment in small workplaces.

Some kind of protective clothing and personal safety items was needed in 90% of the 163 workplaces surveyed. Protective clothing was used in 31%, ear protectors in 28%, eye protectors in 22%, respiratory tract protectors in 18% and other safety items in 1% of the firms. Gloves were the most commonly used type of protective clothing. Protection against risks was proper in one-fourth of the firms, satisfactory in half, and poor or lacking in the rest. Ninety-five percent of the protectors available were appropriate, but only in a few companies were they properly cared for. Seven (12%) industrial firms, 15 (20%) service establishments and 1 (7%) other firm lacked proper protective clothing or safety items. Faults were generally attributed to insufficient knowledge or negligence of responsibilities on the part of the employers. Management should provide more appropriate instruction for workers in the use and, particularly, the maintenance of personal protectors. To be effective, the inspection of the appropriateness of the protectors requires suitable training. This training should also be received by the staff providing occupational health services. Visits to workplaces, as well as health examinations, provide an opportunity to discuss protection and to advise employers and employees on protection. The problems of protection against harmful exposures is closely connected with health counseling. Yet, the provision of proper protectors and the supervision of their use is still the responsibility of the employer.

Exposure of field workers to organophosphorus insecticides: sweet corn and peaches.

Plasma and red blood cell cholinesterase levels of professional agricultural workers engaged in packing sweet corn and thinning peaches were monitored. Workers with extensive contact with mechanically harvested sweet corn (the corn had been treated one or two days before harvest with a combination of ethyl and methyl parathion) exhibited significant depression of cholinesterase. Gloves, worn by 40% of the workers, provided some protection from absorption of pesticide residues. No significant cholinesterase depression was found in workers thinning peaches which had been previously treated with parathion.

Transfer isolator to protect personnel from exposure to peracetic acid.

A transfer isolator is described which confines peracetic acid fumes used in the gnotobiotic operation of isolators. The use of this isolator protects both personnel and animals from contact with peracetic acid, provides additional isolator space and reduces wear on the gloves and sleeves of the main isolator.

The arrhythmogenic effect of static electricity on the dog heart.

Seven dogs, three with surgically-induced acute myocardial infarction, were subjected to the effects of static electricity discharged from our fingertips onto the external end of a transvenous right ventricular pacemaker. Initiation of ventricular beats occurred regularly when shocks were perceptible to the generating person and, not infrequently, when energy levels were below perception. In one dog with myocardial infarction, ventricular fibrillation was clearly related to the static discharge. The data obtained in this study support the recommendations of the Electrical Safety Hazard committee that critical care areas not be carpeted in order to minimize static discharges. In addition to low static floor covering in these areas, one can reduce static charge by the use of foot coverings such as those worn in the operating room. We found that no static charge could be developed when wearing the expandable operating room "booties." Since static charges were transmitted through our fingertips, probably the best means of protecting the electrically sensitive patient against the hazard of static electricity is to instruct personnel to wear rubber gloves whenever direct contact with the external ends of a pacing catheter becomes necessary. Routinely, such exteriorized pacemaker ends should also be covered with a nonconductive substance.

Effect of intraocular lenses on the corneal endothelium.

Methacrylate surfaces adhere to corneal endothelial cell membranes and appear to tear off the cell membranes as they separate. This adhesion appears to cause much of the massive cell damage seen at the time of intraocular lens insertion even in the hands of several groups of very experienced implant surgeons. The damage appears correlated with the incidence of endothelial touch, and may be avoidable both by avoiding contact, even for a brief period, between the endothelium and the intraocular lens during insertion, and by increasing the safety of such lenses through a hydrophilic protective coating which would give a surface similar to human lens epithelium or soft contact lens material which does not damage the endothelium. It is possible that similar damage also plays a role in causing abdominal adhesions through contact with rubber gloves, as well as venous thromboses and urethral strictures.
