Community College of Rhode IslandLatex Product Safety Policy |
|
PURPOSE The purpose of this written policy is the prevention of allergic reactions to natural rubber latex in the Community College of Rhode Island. Latex allergy can result in potentially serious health problems for workers and students who are often unaware of the risk of latex exposure. Such health problems can be minimized or prevented by following the recommendations in this Policy. NIOSH RECOMMENDATIONSThe following recommendations for preventing latex allergy in the workplace are based on current knowledge and a common-sense approach to minimizing latex-related health problems. Evolving manufacturing technology and improvements in measurement methods may lead to changes in these recommendations in the future. For now, adoption of the recommendations wherever feasible will contribute to the reduction of exposure and risk for the development of latex allergy. In this document, the term "latex" refers to natural rubber latex and includes products made from dry natural rubber. Natural rubber latex is the product manufactured from a milky fluid derived mainly from the rubber tree, Hevea brasiliensis.

The National Institute for Occupational Safety and Health (NIOSH) is striving to prevent allergic reactions to natural rubber latex among workers who use gloves and other products containing latex. Latex gloves have proved effective in preventing transmission of many infectious diseases to health care workers. But for some, exposures to latex may result in skin rashes, hives, flushing, itching, nasal, eye, or sinus symptoms, asthma and (rarely) shock. Reports of such allergic reactions to latex have increased in recent years, especially among health care workers. At present, scientific data are incomplete regarding the natural history of latex allergy. Also, improvements are needed in methods used to measure proteins causing latex allergy. This Policy presents NIOSH recommendations for minimizing latex-related health problems in workers and students while also minimizing their exposure to infectious materials. (Note that no glove materials provide absolute protection from all etiological agents; they only reduce exposure risk.) These recommendations include reducing exposures, using appropriate work practices, training and education, monitoring symptoms, and substituting nonlatex products when appropriate. |

TYPES OF REACTIONS TO LATEX Three types of reactions can occur in persons using latex products:
Irritant Contact Dermatitis Chemical Sensitivity Dermatitis Latex Allergy |

LEVELS AND ROUTES OF EXPOSURE Studies of other allergy-causing substances provide evidence that the higher the overall exposure in a population, the greater the likelihood that more individuals will become sensitized. The amount of latex exposure needed to produce sensitization or an allergic reaction is unknown; however, reductions in exposure to latex proteins have been reported to be associated with decreased sensitization and symptoms. Note: The proteins responsible for latex allergies fasten to powder that is used on some latex gloves. When powdered gloves are worn, more latex protein reaches the skin. Also, when gloves are changed, latex protein/powder particles get into the air and can be distributed by a building's ventilation system. They can be inhaled and contact body membranes of persons far removed from the site of latex use. In contrast, work areas where only powder-free gloves are used show low levels or undetectable amounts of the allergy-causing proteins. Wearing latex gloves during episodes of hand dermatitis may increase skin exposure and the risk of developing latex allergy. The risk of progression from skin rash to more serious reactions is unknown. However, a skin rash may be the first sign that someone has become allergic to latex and that more serious reactions could occur with continuing exposure. |

WHO IS AT RISK? Persons with ongoing latex exposure are at risk for developing latex allergy. They include health care workers and students (physicians, nurses, nurse's aides, dentists, dental assistants, dental hygienists, operating room employees, laboratory technicians, phlebotomists and hospital housekeeping personnel) who frequently use latex gloves and other latex-containing medical supplies. Workers who use latex gloves and other products less frequently (law enforcement personnel, ambulance attendants, funeral-home workers, fire fighters, painters, gardeners, and food service workers) may also develop latex allergy. Workers in factories where latex products are manufactured can also be affected. Atopic individuals (persons with a tendency to multiple allergic conditions) are at increased risk for developing latex allergy. Latex allergy is also associated with allergies to certain foods especially avocado, potato, banana, tomato, chestnuts, kiwi fruit, and papaya. People with spina bifida are also at increased risk for latex allergy. |

DIAGNOSING LATEX ALLERGY Latex allergy should be suspected in anyone who develops certain symptoms after latex exposure, including nasal, eye, or sinus irritation; hives; shortness of breath; coughing; wheezing; or unexplained shock. A physician should evaluate any exposed person who experiences these symptoms, since further exposure could result in a serious allergic reaction. A diagnosis is made by using the results of a medical history, physical examination, and tests. Taking a complete medical history is the first step in diagnosing latex allergy. In addition, blood tests approved by the Food and Drug Administration (FDA) are available to detect latex antibodies. However, no FDA-approved materials are yet available to use in skin testing for latex allergy. Skin testing and glove-use tests should be performed only at medical centers with staff who are experienced and equipped to handle severe reactions. Testing is also available to diagnose allergic contact dermatitis. Occasionally, tests may fail to confirm a worker who has a true allergy to latex, or tests may suggest latex allergy in a worker with no clinical symptoms. Therefore, test results must be evaluated by a knowledgeable physician. TREATING LATEX ALLERGY Once a person becomes allergic to latex, special precautions are needed to prevent exposures during work as well as during medical or dental care. Certain medications may reduce the allergy symptoms, but complete latex avoidance (though quite difficult) is the most effective approach. Many facilities maintain latex-safe or latex-free areas for affected patients and workers. HOW COMMON IS LATEX ALLERGY? The prevalence of latex allergy has been studied by several methods: Questionnaires to assess reactions to latex gloves; Medical histories of reactions to latex-containing products; Skin tests; Tests for latex antibodies in a worker's blood. Reports about the prevalence of latex allergy vary greatly. This variation is probably due to different levels of exposure and methods for estimating latex sensitization or allergy. Recent reports in the scientific literature indicate that about 1% to 6% of the general population and about 8% to 12% of regularly exposed health care workers are sensitized to latex. Among sensitized workers, a variable proportion have symptoms or signs of latex allergy. Several reasons may exist for the large numbers of latex allergies recently reported in workers and students:
