OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at http://www.osha.gov.

Dear Mr. Hennelly:
Thank you for your letter of March 29, 1993, in which you requested that OSHA provide an opinion concerning two different methods of inner cannula care, the disposable cannula and the reusable cannula.
OSHA does not review or endorse products as you have requested. The final determination of compliance with OSHA's Bloodborne Pathogens standard, 29 CFR 1910.1030, must take into account all factors pertaining to the use of such devices at a particular worksite. This must include an evaluation through direct observation of employee work practices as well as an evaluation of the potential exposure to blood or other potentially infectious materials (OPIM) which the use of the device will cause an employee.
As you are aware, the Bloodborne Pathogens standard attempts to minimize the employee's exposure to blood or OPIM. OSHA does not mandate that facilities use disposable devices in order to accomplish this goal. The employer should make the determination whether the reusable or the disposable device better satisfies their needs.
We are enclosing the copy of the videotape which you provided us for review. We appreciate your interest in safety and health.

Presently, over ninety percent of adult tracheostomy patient's trach tubes employ inner cannulas. The inner cannula of a trach tube is primarily a safety feature as it collects secretions, and thus is taken out and replaced with a sterile inner cannula, or re-cleaned, depending on the type of trach tube.
I have enclosed sample protocols of tracheostomy care with disposable inner cannulas and tracheostomy care with reusable inner cannulas. I have also enclosed a video on trach care.
Since Mallinckrodt Medical manufactures trach tubes with disposable and reusable inner cannulas, we are very interested in OSHA's opinion on the two different methods of inner cannula care. Specifically: based on your 29 CFR 1910.1030 Occupational Exposure to Bloodborne Pathogens Guidelines, what protective measures should a care-giver take when re-cleaning a patient's inner cannula? And, could disposable inner cannulas be considered an engineering control devise' (ie. needleless syringes, Sharps Containers, ect.) as they are often used as a means to reduce the risk of infection?
Clinicians often come to us for advise on trach care and it is our desire to be in accordance with the Occupational Safety and Health Administration. Thank you for your attention to this matter.
Tracheostomy care is performed using aseptic technique and in accordance with a physician's order.
