No. Cold sterile is not OSHA approved, because OSHA does not approve or certify any sterilization or disinfection method. OSHA regulates the workplace, not the product. What the agency does is require employers to protect workers from bloodborne pathogens and chemical hazards, which means the employer, not OSHA, is responsible for choosing a reprocessing method that actually fits the instrument and following it correctly. The label “cold sterile” is itself misleading, since the room-temperature chemical soaks it describes almost never produce true sterility.
What OSHA Actually Regulates Here
OSHA’s job is worker safety, not product clearance. The Bloodborne Pathogens Standard at 29 CFR 1910.1030 is the rule that governs instrument reprocessing from the worker-protection side. It requires a written exposure control plan and engineering and work-practice controls that keep employees away from blood and other infectious materials, which includes reprocessing contaminated instruments so workers aren’t exposed while handling them. The standard names no specific chemical, machine, or brand. It puts the burden on the employer to match the method to the level of contamination and the instrument’s intended use.
Where no specific standard covers a hazard, OSHA falls back on the General Duty Clause, which requires every employer to provide a workplace free from recognized hazards likely to cause death or serious physical harm. If an employer uses a chemical soak on an instrument that needed full sterilization and a worker is exposed to a pathogen because of it, OSHA can cite under the Bloodborne Pathogens Standard, the General Duty Clause, or both.
Who Does Approve Sterilization Products
Three federal agencies share this territory, and none of them is OSHA.
The FDA regulates liquid chemical sterilants and high-level disinfectants used on medical devices, reviewing premarket submissions for safety and effectiveness. The FDA also recommends that liquid chemical sterilants be used only on critical devices that are heat-sensitive and incompatible with steam, gas plasma, or other physical sterilization methods. Chemical soaking is meant to be a last resort even for the products the FDA has cleared.
The EPA regulates surface disinfectants and gaseous sterilants under the Federal Insecticide, Fungicide, and Rodenticide Act, requiring registration and effectiveness data. The CDC publishes the infection control guidelines that OSHA and healthcare facilities rely on as best practice. Under a longstanding agreement between the two, the FDA handles liquid chemical sterilants for medical devices and the EPA handles environmental surface disinfectants and gaseous sterilants.
Cold Sterile Is Usually Not Sterilization
Most of the confusion around “cold sterile” comes from the name. When people say they are cold-sterilizing an instrument, they almost always mean high-level disinfection: soaking in a chemical solution at or near room temperature. High-level disinfection kills nearly all microorganisms but leaves behind a small number of bacterial spores. True sterilization eliminates every form of microbial life, spores included. That difference between “nearly all” and “all” is what separates a soak that is acceptable for some instruments from a process that is legally required for others.
The CDC and FDA both reference the Spaulding Classification, which sorts instruments into three categories based on infection risk. Each category demands a different level of reprocessing, and calling a chemical soak “sterile” doesn’t move an instrument out of the category it belongs in.
When a Chemical Soak Is Acceptable
High-level disinfection is appropriate for semi-critical devices, meaning instruments that contact mucous membranes or non-intact skin but do not penetrate sterile tissue. Flexible endoscopes, respiratory therapy equipment, and certain dental instruments are the common examples. For these items, a properly performed chemical soak can reduce contamination to a safe level.
“Properly performed” is doing serious work in that sentence. The solution has to hold the correct concentration, temperature, and contact time listed in the manufacturer’s instructions. Common high-level disinfectants include glutaraldehyde, hydrogen peroxide, and ortho-phthalaldehyde (OPA), and each has its own required soak time and concentration. Skipping cleaning first also breaks the process, because blood and tissue shield the instrument surface from the chemical. A soak on a dirty instrument is not a soak at all.
When Only Sterilization Will Do
p>Critical devices, the ones that enter sterile tissue or the vascular system, require true sterilization with no exceptions. Surgical instruments, implants, cardiac catheters, and needles all fall here. Using high-level disinfection on a critical device violates accepted infection control practice and creates a direct pathogen pathway to both patients and the workers who handle those instruments.
Acceptable sterilization methods include steam autoclaving, dry heat, ethylene oxide gas, hydrogen peroxide gas plasma, and, in manufacturing settings, gamma irradiation. The FDA has specifically stated that liquid chemical sterilants should be limited to heat-sensitive critical devices that cannot tolerate any of these other methods. If an instrument can survive an autoclave, soaking it in chemicals instead is not compliant.
The Chemical Hazards OSHA Does Cite
Even where a chemical soak is the right process for the instrument, OSHA still cares about what those chemicals are doing to the workers using them. This is where “cold sterile” employers get cited most often.
Glutaraldehyde is widely used and is one of the more hazardous chemicals in healthcare settings. OSHA has no formal Permissible Exposure Limit for it, but NIOSH set a Recommended Exposure Limit of 0.2 ppm and the American Conference of Governmental Industrial Hygienists recommends a ceiling of 0.05 ppm. In endoscopy units without local exhaust ventilation, workers were exposed to average concentrations of 0.093 ppm, nearly double the ACGIH ceiling; adding local exhaust ventilation dropped that to 0.022 ppm. OSHA’s Permissible Exposure Limit for hydrogen peroxide is 1 ppm as an 8-hour time-weighted average. OPA is corrosive to skin and eyes, can cause allergic skin reactions, and repeated exposure can trigger occupational asthma whose symptoms sometimes appear hours after contact. Workers who develop asthma symptoms from OPA should avoid all further contact with it.
Ventilation, PPE, and Emergency Equipment
Adequate ventilation is not optional wherever chemical sterilants or high-level disinfectants are used. If workers are reporting eye irritation, headaches, or respiratory symptoms around these chemicals, that is a recognized hazard OSHA can cite. Workers handling chemical sterilants need chemical-resistant gloves matched to the specific chemical (the Safety Data Sheet specifies compatible glove materials), a splash apron, and eye protection. Where splashing is possible, a face shield is warranted over goggles alone.
OSHA also requires suitable facilities for quick drenching or flushing of the eyes and body within the work area for immediate emergency use. A worker splashed with glutaraldehyde or OPA needs to flush the area with water for at least 15 minutes, which means an eyewash station and emergency shower within reach, not down the hall.
Training and Safety Data Sheets
Under the Hazard Communication Standard at 29 CFR 1910.1200, any employer using hazardous chemicals must train employees before they handle those products. Training covers how to detect the chemical’s presence or release, the specific health hazards, protective measures, and how to read and use Safety Data Sheets. SDSs for every chemical sterilant must be accessible to employees in their work area at all times, with a backup for power outages. New chemical products trigger new training before workers handle them.
What It Costs to Get This Wrong
OSHA penalties in this area can stack. As of January 2025, a serious violation carries a maximum penalty of $16,550 per violation. A willful or repeated violation carries a maximum of $165,514 per violation. A failure-to-abate violation, where a cited problem is not fixed by the deadline, runs up to $16,550 per day beyond that deadline.
Deficiencies in a reprocessing room tend to be counted separately: inadequate training, missing Safety Data Sheets, no exposure control plan, improper reprocessing method, insufficient ventilation, and missing PPE can each generate its own citation. The FDA, state health departments, and professional licensing boards all have their own enforcement authority over sterilization practices as well, and a single reprocessing failure can pull in more than one of them at once.
So the short version stays short. OSHA doesn’t approve cold sterile because OSHA doesn’t approve any method. The employer picks the method, matches it to what the instrument actually needs under the Spaulding categories, follows the chemical manufacturer’s instructions exactly, and controls the chemical hazard for the worker doing the soaking. That is what compliance looks like; the phrase “OSHA approved” on a chemical sterilant is not.
