The dangers of including latex gloves in your PPE selection
Latex gloves have proven effective in many lines of work, including health care and general industry. But for some workers, exposures to latex may result in allergic reactions, some serious and life-threatening. When selecting PPE, the employer must make an educated decision whether or not to include latex gloves as an option.
An allergic reaction to natural rubber latex (NRL) is a result of the human body mistaking certain proteins found in natural latex for a harmful substance. Allergy symptoms can range from mild to severe. While a known hazard exists, it doesn’t necessarily impact everyone equally. Whether someone has a reaction will depend on how sensitive they are and their amount of exposure (either through touch or inhalation). A reaction can worsen with each additional latex exposure. Symptoms can include:
- Itching, skin redness, hives, or rash (all considered mild)
- Sneezing, runny nose, watery eyes, scratchy throat, difficulty breathing, wheezing, cough (all considered moderate)
- Difficulty breathing, hives, swelling, nausea and vomiting, drop in blood pressure, dizziness, loss of consciousness, confusion, rapid or weak pulse (all considered life-threatening)
Latex allergy is only addressed in specific OSHA standards for general industry, in particular hand protection (1910.138) and bloodborne pathogens (1910.1030). The information included is not descriptive or specific as to why latex should be considered a potential health hazard.
- The hand protection standard mentions that the employer must “base the selection of appropriate hand protection on an evaluation of the performance characteristics of the hand protection relative to the task(s) to be performed, conditions present, duration of use, and the hazards and potential hazards identified.”
- The bloodborne pathogen standard goes into slightly more detail in section (d)(3)(iii) where it states, “hypoallergenic gloves, glove liners, powderless gloves, or other similar alternatives shall be readily accessible to those employees who are allergic to the gloves normally provided.”
It is also mentioned by OSHA in a 1997 letter of interpretation that “latex gloves themselves may present their own hazards.” It goes on to say that latex gloves “have been associated with dermatitis, sensitization, and allergic reactions. When feasible, their use should be limited as much as possible. It is the employer’s responsibility to select the appropriate hand protection based on an evaluation of the tasks to be performed.” OSHA also suggests the employer “consult the manufacturer of any gloves for the suitability of their gloves for chemical protection and the recommended time they can be expected to be safely worn.”
Even though the risk of latex allergy exists, they are still identified as a chemical-resistant glove of choice. According to OSHA’s Chemical Resistance Selection Chart for Protective Gloves, latex gloves were recognized as a “very good” choice when handling chemicals such as acetic acid, butyl alcohol, formaldehyde, glycerin, and sodium hydroxide.
OSHA has identified latex gloves as being comfortable to wear, featuring outstanding tensile strength, elasticity, and temperature resistance. In addition to resisting abrasions caused by grinding and polishing, OSHA mentions these gloves protect employees’ hands from most water solutions of acids, alkalis, salts, and ketones.
Allergy to latex was first recognized in the late 1970s. The first anaphylactic responses brought on by latex surgical gloves were documented in 1984. NRL became well recognized throughout the 1980s as a significant trigger of occupational allergies and asthma, particularly in healthcare workers who used powdered NRL gloves. Between 1988-1992, the Food and Drug Administration (FDA) received more than 1,000 reports of adverse health effects from exposure to latex, including 15 deaths due to such exposure. While the understanding and prevention of NRL allergy have advanced significantly, the condition may still be a source of worry.
Key to remember: Awareness of the sensitization risk associated with the use of latex gloves should still be present in all occupational settings, especially when selecting PPE options for employees.
