9.1 Implements, Equipment, Supplies, and Disinfection

Why this chapter sits on the New Jersey exam

The NIC New Jersey Cosmetologist-Hair Stylist theory outline (CIB Domain 2.B) asks you to identify equipment, implements, and supplies used in hair services and to apply proper disinfection. That is not a catalog-memorization item. On a New Jersey paper it is a law-plus-skill item: you must know what each tool is for and how N.J.A.C. 13:28-3.1 (premises) and N.J.A.C. 13:28-3.2 (sanitizing implements and tools) force you to handle it after every patron. Shop licensing under N.J.A.C. 13:28-2.5 then tells you which fixtures the shop must have so that sequence is even possible.

A cosmetologist-hairstylist shop is not a classroom drawer of mixed plastic. Inspectors look at the hydraulic chair, the workstation, the shampoo area, the designated cleaning area, and the closed receptacles at each station. If those pieces are dirty, broken, or used as a parking lot for yesterday's shears, you have already failed 13:28-3.1(d) and 13:28-3.1(f) before anyone asks about a fade or a blunt line.

Four categories you must not mix up

Domain 2.B groups hair-service items the way a well-run station is actually set. Infection-control duty follows the category, not the brand name on the handle.

The exam trap is treating a paddle brush like equipment (wipe the station and you are done) or treating a neck strip like a multi-use comb (rinse and reuse). Equipment is cleaned in place. Implements that touch the patron go through 13:28-3.2. Supplies that cannot be sanitized are one client, then trash.

Equipment: chair and workstation

13:28-3.1(a)–(c) set the room: shops, including lavatories, must be properly lighted and ventilated, must have an adequate supply of potable water, and must dispose of waste so it is not a public-health hazard. Those sentences are why a dark, unventilated back room with a bucket of hair clippings is not a legal workstation.

The hydraulic styling chair exists so you raise or lower the client, not your spine. For infection control, treat the chair as equipment: hair, product, and skin oils collect on the seat, headrest, pump, and base. Wipe visible soil during the service as needed; clean the chair between patrons; keep torn vinyl out of service because cracked padding is no longer a cleanable, nonporous surface. 13:28-3.1(d) says equipment must be sanitary and in good repair — a broken pump that dumps the client toward the floor is a safety failure as much as a sanitation failure.

The workstation is the horizontal surface plus drawers, mirror ledge, and tool wells. Hair left in a drawer is not a style choice; it is soil. 13:28-3.2(a)5 requires a clean drawer for disinfected tools. A drawer packed with hair, clips, and a candy bar is not that drawer. 13:28-2.5 also requires a clean, closed receptacle for sanitized implements at each workstation and a separate closed receptacle at the station that can hold soiled implements completely immersed in an enzyme solution before cleaning and disinfection. Open trays of mixed clean and dirty shears fail both rules at once.

Shampoo equipment (bowl, reclining chair, hose) is cleaned as a fixture. The cape and towels used at that bowl are supplies, not part of the plumbing. Do not fold a used shampoo cape over the clean-tool drawer and call the station reset.

Cutting shears versus thinning shears versus razors versus clippers

Cutting shears (haircutting scissors) have two matched blades, a pivot, and usually a finger rest (tang). They establish length and line: blunt, graduated, and layered cutting. Handle geometry matters for later ergonomics, but the sanitation point is simpler: steel shears are nonporous if intact. Hair, oil, and product at the pivot are soil. If you drop them into disinfectant with hair still in the crimps, you have skipped 13:28-3.2(a)1. Tension that is too loose lets hair fold; tension that slams the blades shut chews the edge — that is equipment-in-good-repair, not a fashion preference. Never store shears wet: 13:28-3.2(a)5 is air-dry, then the clean drawer. Water left in the pivot is how rust starts, and rust is damage. Damaged metal is removed from use in the ultrasonic/manicure path in 13:28-3.2(b)3 (pitting and rust); the same professional standard applies to a pitted shear you would still put on a scalp.

Thinning shears (texturizing or blending shears) have teeth or notches on one or both blades. They remove bulk and weight and soften a line; they do not replace cutting shears when you need a clean guideline. Fewer, wider teeth remove more hair per bite (chunkier texture). More, finer teeth blend more softly. The Board does not publish a required tooth count — do not invent one. Sanitation is harder than on a straight blade because hair packs the teeth. If you cannot get the hair out, you cannot complete the detergent step, and 13:28-3.2(d) tells you what to do with a tool that cannot be sanitized: discard it. A thinning shear that is used as a “quick mix” on every head and then laid in a drawer with last hour’s hair still in the teeth is a cross-contamination machine.

Razors used in hair services are usually a hair shaper (often with a guard) for tapering and texturizing, typically on wet hair, or a straight razor in the barbering portion of the curriculum. The blade that contacts skin or hair is commonly disposable. 13:28-3.2(d) already names implements that cannot be sanitized and requires discard after each use; a used blade is not a reusable comb. The handle or shaper body, if nonporous and intact, is a multi-use implement and must go through 13:28-3.2(a) after the blade is removed. Do not slide a fresh blade onto a handle still filmed with hair and product and call that a new tool. Used blades are sharps: they go into a puncture-resistant container, not the open trash next to the candy dish.

Clippers (and trimmers) are both an implement (the blade that cuts) and an electrical appliance (the motor and cord). Domain 2.B lists them with tools; 13:28-3.1(f) lists electrical appliances. Guards and detachable blades that can take washing and chemical processing follow 13:28-3.2. The motor housing usually cannot be immersed — section 9.2 covers that limit without inventing a New Jersey wipe recipe the Board has not published. For this section, remember the principle that already lives in 13:28-3.2(a)1: if hair is still in the blade, you have not cleaned the tool.

Combs, brushes, and why trapped hair defeats disinfection

Hard cutting combs, tail combs, wide-tooth combs, and barber combs that are intact plastic or hard rubber are nonporous. They still fail disinfection when hair is packed between the teeth. Disinfectant labels and 13:28-3.2(a) agree on the same physics: the chemical step is for a cleaned surface. Organic soil (hair, sebum, product) shields microbes and consumes the disinfectant. A comb dunked dirty is a comb that was never processed.

Brushes are where students lose easy points. A vent brush or a nylon-bristle brush on a hard, nonporous base can be a multi-use implement if you can remove every hair and wash the base and bristles. A porous cushion, a cracked wooden handle, natural bristles, or a pad that still holds a mat of hair cannot be brought to a clean, contactable surface. New Jersey does not publish a Virginia-style named ban on natural hairbrushes. It does publish 13:28-3.2(d): discard all implements and tools that cannot be sanitized. That is the New Jersey answer. Do not “spray and pray” a matted paddle brush and put it on the next client.

Clips and sectioning tools are implements. They collect product at the spring. Clean them; do not store them in the same drawer as sanitized shears if they are still soiled.

Supplies: towels, drapes, and single-use neck strips

13:28-3.1(e) is the linen rule in one sentence: all linens and toweling used in the shop shall be laundered and sanitized before each and every direct contact with a patron. In lieu of laundered and sanitized linens, disposable toweling may be used. There is no “the towel looked dry so I flipped it” exception. A towel that touched one neck is done until it has been laundered, or it was disposable and it is trash.

Drapes (capes) protect clothing and skin. Know the job, not a brand:

• A shampoo cape is waterproof (typically vinyl or similar). It belongs at the bowl so water and shampoo do not soak street clothes. It is a multi-use textile/fixture cover: clean it according to the material; do not use a soaking-wet shampoo cape as the only barrier during a chemical service.
• A cutting cape is used for dry cutting and styling. Hair still sheds onto it; treat it as soiled after the patron.
• A chemical cape (often vinyl) is for color, lightener, perm, and relaxer work. It is a splash barrier, not a substitute for a skin-protecting cream at the hairline. Never pin a chemical-soaked towel against the neck and call that draping.

The neck strip (neck band, sanitary strip) is a single-use paper or tissue barrier between the cape and the patron’s skin. Domain 2.B lists it with supplies for a reason: the cape is reused after appropriate cleaning; the strip is not. A new strip goes on for each patron. It is not a linen under 13:28-3.1(e) that you launder. If it is damp, torn, or has hair in it, it has already failed as a barrier — replace it during the service. Closing the cape over bare skin “because we ran out of strips” recreates the exact contamination path the strip was invented to stop: the next patron’s neck against last patron’s cape.

13:28-2.5 (as applied to cosmetology and hairstyling shops) requires closed containers for clean and soiled linens. Clean towels do not live on an open shelf above the dirty-hair bag. Soiled linens do not sit on the workstation top. That is the same logic as the closed waste container accessible to each workstation: hair and used strips are waste, not décor.

The New Jersey sanitize sequence — in the Board’s order

13:28-3.2(a) is the sequence you should be able to write from memory:

1. Clean all implements and tools thoroughly with a mild alkaline detergent to remove soil, blood, or any other foreign material.
2. Rinse with tap water after cleaning.
3. Process with a chemical disinfectant registered by the EPA and labeled as tuberculocidal, for the contact time on the product label, or process in an autoclave registered with the FDA.
4. Follow the manufacturer’s instructions when using the chemical disinfectant.
5. Allow disinfected implements and tools to be air-dried and store them in a clean drawer.

Step 3 is a fork, not a maybe: chemical or autoclave. Step 4 is not optional small print — contact time, dilution, and whether the product is even labeled for that surface come from the label, which is what “tuberculocidal” and “EPA-registered” attach to. Step 5 is the New Jersey storage rule. Older shop habits of leaving metal in a wet jar at the station as “storage” do not match air-dried … clean drawer. The 2009 shop-equipment amendments also moved shops away from requiring a wet sterilizer and dry sterilizer at each station and toward a designated cleaning area, an ultrasonic unit, and closed receptacles. On the exam, “I kept them in the jar so they stayed disinfected” is the wrong ending to a correct beginning.

13:28-3.2(b) adds a manicuring path (enzyme pre-soak, ultrasonic cycle, inspect for pitting and rust, then tuberculocidal or autoclave, then rinse, dry, clean drawer). That subsection is written for reusable implements used in manicuring services. A cosmetology shop still must have the ultrasonic unit and enzyme receptacle under 13:28-2.5 because the C-H shop performs nail services and because metal tools are cleaned there. Do not claim the Board published a 10-minute ultrasonic mandate for hair shears in 13:28-3.2(b) — that text is the manicuring protocol. Do claim this: if you use the shop ultrasonic on metal hair tools, you still owe the detergent / rinse / tuberculocidal-or-autoclave / air-dry / clean drawer logic, and you still remove damaged, pitted, rusted tools from service.

13:28-3.2(d) closes the loop: discard after each use emery boards, orangewood sticks, and all implements and tools that cannot be sanitized. Hair services inherit the last clause every time a porous brush, packed comb, cracked clip, or disposable razor blade cannot take the sequence.

Shop 13:28-2.5: the fixtures that make 3.2 possible

For an initial cosmetology and hairstyling shop license, 13:28-2.5 is why the cleaning story is not “whatever fits in my kit.” The shop must include a designated area for cleaning and disinfecting implements and tools, one ultrasonic unit for cleaning metal implements and tools, a clean closed receptacle at each workstation that allows soiled implements to be completely immersed in an enzyme solution before cleaning and disinfection, a clean closed receptacle for storage of sanitized implements at each workstation, a closed waste container accessible to each workstation, and hair drying facilities and/or hair drying equipment, along with the other physical items the section lists (including the shampoo setup and linen containers described in the shop-license rules). You do not disinfect shears in the beverage fridge. You do not share one open “clean” cup across four chairs.

Put Domain 2.B and Subchapter 3 together and the practical picture is strict: chair and station stay in repair and clean; shears, thinning shears, razors, combs, and brushes are either fully processed or thrown out; towels are laundered or disposable; neck strips are one-and-done; the shop’s designated room and closed receptacles are part of the answer, not interior decorating.
