|(a) EPA-registered bactericidal, fungicidal, and virucidal disinfectants shall be used as follows: (1) Implements and surfaces shall first be thoroughly cleaned of all visible debris prior to disinfection. EPA-registered bactericidal, fungicidal, and virucidal disinfectants become inactivated and ineffective when visibly contaminated with debris, hair, dirt and particulates. (2) Some disinfectants may be sprayed on the instruments, tools, or equipment to be disinfected. (3) Disinfectants in which implements are to be immersed shall be prepared fresh daily or more often if solution becomes diluted or soiled. (4) In all cases the disinfectant shall be used in accordance with the manufacturers' recommendation or other guidance in this rule. (5) These chemicals are harsh and may affect the long term use of scissors and other sharp objects. Therefore, the Department recommends leaving items in solution in accordance with the manufacturers' recommendation for effective disinfection. (b) Chlorine bleach solutions shall be used as follows: (1) Chlorine bleach at the appropriate concentration is an effective disinfectant for all purposes in a salon. (2) Chlorine bleach solutions shall be mixed daily. (3) Chlorine bleach shall be kept in a closed covered container and not exposed to sunlight. (4) Chlorine bleach may affect the long-term use of scissors and other sharp objects so the Department does not recommend leaving items in bleach solution beyond 2 minutes for effective disinfection (5 minutes if disinfecting for blood contamination). (5) Chlorine bleach vapors might react with vapors from other chemicals. Therefore chlorine bleach shall not be placed or stored near other chemicals used in salons (i.e. acrylic monomers, alcohol, or other disinfecting products) or near flame. (6) Used or soiled chlorine bleach solution shall be properly disposed of each day. (c) Isopropyl or Ethyl alcohols shall be used as follows: (1) Isopropyl alcohol at a concentration of at least 70% and ethyl alcohol at a concentration of at least 90% are low-level disinfectants. (2) Alcohol shall not be used to clean and disinfect blood or body fluid. (3) All alcohol shall be kept in a covered container. Alcohol deteriorates in some plastics, metals and rubber items. (4) Alcohol may affect the long-term use of scissors and other sharp objects. (5) The Department recommends leaving items in alcohol in accordance with the manufacturer's recommendation for effective disinfection. When using alcohol on surfaces other than non-porous materials, the time of contact shall be between 1 to 3 minutes after proper cleaning that removed all visible debris. (6) Alcohol may be sprayed onto porous or absorbent surfaces after cleaning, with contact time on the surface of the item for at least 1 minute, provided the porous items have not contacted broken or unhealthy skin or nails.
