Are surgical masks flammable?

Personal protective equipment (PPE) is used to shield them and patients for operators in surgical environments. FDA cleans some EPI as class II medical devices (such as OPMs) and controls some (e.g., OPC cover) as exempt devices for Class I. The N95 Facial Filtering Facepiece Respirator (FFR), and Power Air Purifying Respirators (PAPRs) are certified for respiratory protection by the National Institute of Occupational Safety and Health (NIOSH). The NIOSH-approved FFR, which is also excluded by the FDA for medicinal use, is one form of PPE, a 'surgical N96 breather.' The surgical setting raises unusual threats such as surgical fire potential. FDA demands flammability monitoring and additional criteria for SM and surgical N95 breathers as part of its substantial equivalence determination procedure. There is a shortage of evidence on PEP flammability seen in healthcare. We assume that the most widely used PPE would pass an industry benchmark, such as the 16 CFR 1610 flammability test, irrespective of whether controlled or cleared by the FDA.

If you develop personal security devices such as operating masks (PPE), facial and respiratory shields or require assistance for a full 510K request according to FDA Emergency Use Authorisation (EUA) Regulation, Eurofins Medical Product Testing offers fabricators extensive testing support for all approvals levels.

Comprehensive Testing Services:

  • Penetration of Synthetic Blood Testing: The procedure is used to measure the tolerance to penetration in a high-speed stream of synthetic blood through surgical masks. To assess product acceptability, a visual test of blood penetration is used.
  • Flammability Testing: The assessment of the flammability used in the manufacturing industry of medical facial masks. Specimens are cut to the specified form and sent for one second to a standardised blaze. To assess material acceptability, the time needed for the flame's propagation and ignition resistance are used.
  • Biocompatibility: To assess the need for further ISO 10993 toxicological testing. A health-care facial mask is a long-term touch surface device for cumulative use. ISO 10993-5 (Cytotoxicity), ISO 10993-10 are recommended for research (Irritation & Sensitization).

Flammation Test 

The Flammability examination assesses the flammability of medical textiles, such as facial masks, clothes and mats. The testing procedure has been configured to adhere to 16 CFR 1610 component. The ASTM F2100 (Standard Materials Efficiency Criteria Used in Medical Face Masks) includes this test to ensure that all facial masks follow the class 1 flammability criteria. For 510(k) submissions to the FDA checking is also important. Nelson Laboratories will run all ASTM F2100 experiments in addition to the flammability test.

Breathing flammability and other PPE is tested according to CS-191-53 (16 CFR1610) procedure (Federal Register, 2008; U.S. Consumer Product Safety Commission, 2008) of the Consumer Product Safety Commission (CPSC) for airworthiness and other fabrics (Model M233G, SDL Atlas LLC, Rock Hill, SC). A test chamber, specimen stand, specimen holder, ignition system and an automatic timing mechanism are the key components of the flammability tester. The test chamber is an air chamber ( 35,3 cm (H) — 36,8 cm (W) — 21,6 cm (D) — with a metallic draft proof ventilated chamber. The front of the chamber has a glass door that allows the whole test to be viewed. There is a ventilation strip in the base of the door on the front of the appliance.

Each test unit or material fabric was allocated an ignition class with an average brûling time. Class 1 inflammability devices or components show a >3.5 sec burning time and do not readily burn. Class 3 products or components are burnt at less than < 3.5 sec. Three alternate test results are available. The first finding is that the specimen does not ignite. The second potential finding is the specimen ignites but does not spread the test specimen volume. The third potential consequence is the specimen ignites and burns the whole sample period, but without splitting the flame under the timing thread. The time device does not provide a burn time in this situation. The Class 1 inflammability rating is assigned to these specimens. Only in the original state were RPDs and other cloth materials tested.

To validate the effects of the flame retardancy in our laboratory, the 16 CFR 1610 flammability checks per third parties' independent laboratory (TPI) were also used to test five of 11 N95 FFR models. Four out of six N95 model models reviewed in a previous review and one out of the remaining five models chosen in this study was included in the five N95 model models.

Study Outline

The flame retardancy test decides the moment the substance is fired. Fuel is used in all products with natural or cellulose regeneration as well as some completed and unfinished textiles composed of other natural or synthetic fibres. The pace and strength of flames in which these textile items fire, and their ease to ignite, can pose a risk to the wearer.

Class 1 inflammability degree was seen in all of the PPE samples. A FDA Required for Flammability revealed that all 11 non-FDA certified NIOSH- certified N95 FFR models were appropriate for use as surgical N95 air breathers given that they met Fluid Resistance and other criteria needed by FDA. The vendors have not sent these versions for FDA approval as these instruments cannot actually be sold as N95 surgical aircraft. A unified mechanism is underway between NIOSH and FDA to increase the effectiveness of existing systems requiring both FDA clearance and NIOSH approval. The process can be streamlined by using flammability checks, fluid and other criteria in the NIOSH Approval Process that identified N95 FFR models that fulfil FDA guidelines for surgical N95 respirators. This process can be simplified by The streamlined process would guarantee that the same performance recommendations/standards would adhere to all N95s used in healthcare.
