New Standard Will Aid in Color Calculation of Objects

ASTM Committee E12 on Color and Appearance


According to ASTM member Hugh Fairman, legacy standard E308 gathered data and pre-calculated weight sets for doing what is called “tristimulus integration,” which determines the actual color of a measured spectral reflectance or spectral power curve. While this standard is still useful in certain cases, a need has grown for the more updated practice described in E3415 to respond to interest in how illumination is perceived on painted surfaces.

‘The Barber of Seville’ by Luis Alvarez Catalá

Codes, standards and licensing for barbering schools and cosmetology academies are governed by local regulations; or local adaptations of national standards-setting organizations.  

Northern Michigan University | Marquette County

Building Codes

  1. Minimum Floor Space
    • Schools must provide adequate space for instruction and practice. For example, California requires a minimum of 3,000 square feet for cosmetology schools (which often include barbering), with at least 2,000 square feet dedicated to working, practice, and classroom areas. Additional space (e.g., 30 square feet per student beyond the first 50) may be required as enrollment increases.
    • Rooms for practical work must be sized appropriately, such as at least 14 feet wide for one row of barber chairs or 20 feet for two rows (California standard).
  2. Ceiling Height
    • Practice and classroom areas often require a minimum ceiling height, such as 9 feet, to ensure proper ventilation and comfort (e.g., California Building Code).
  3. Floor Finish
    • Floors in areas like restrooms or workspaces must be made of nonabsorbent materials (e.g., tile) to facilitate cleaning and maintain hygiene.
  4. Separation from Other Uses
    • Barbering schools must be distinct entities, not combined with residential spaces or unrelated businesses (e.g., Nevada’s NAC 643.500).
  5. Compliance with Local Building and Zoning Codes
    • Facilities must adhere to local ordinances for construction, occupancy, and zoning, ensuring the building is structurally sound and legally permitted for educational use (e.g., Virginia’s 18VAC41-20-270).
  6. Accessibility
    • Buildings must comply with accessibility standards (e.g., ADA in the U.S.), providing ramps, wide doorways, and accessible restrooms.

Occupational Safety and Health Administration: Bloodborne Pathogen Safety Standards


Safety

  1. Fire Safety
    • Compliance with the State Uniform Fire Prevention and Building Code (e.g., New York’s 19 NYCRR Parts 600-1250) or equivalent, including fire exits, extinguishers, and alarms.
    • Emergency exits must be clearly marked and unobstructed.
  2. Electrical Safety
    • All electrical equipment (e.g., clippers, dryers) must be regularly inspected (e.g., PAT testing in some regions) to prevent shocks or fires.
  3. Ventilation and Temperature Control
    • Adequate ventilation systems are required to maintain air quality and a safe working temperature, protecting students and instructors from fumes or overheating.
  4. First Aid and Emergency Preparedness
    • A stocked first aid kit must be available, and schools should have protocols for handling accidents or emergencies.
  5. Equipment Safety
    • Tools and workstations (e.g., chairs, sinks) must be maintained in good condition to prevent injuries. Hazardous tools like razor-edged implements for callus removal are often prohibited (e.g., California regulations).
  6. Occupational Safety
    • Compliance with OSHA (Occupational Safety and Health Administration) or state equivalents, such as Virginia’s Department of Labor and Industry standards, to protect against workplace hazards like chemical exposure or repetitive strain.


Hygiene

  1. Sanitation of Facilities
    • Schools must be kept clean and sanitary at all times, including floors, walls, furniture, and workstations (e.g., Virginia’s 18VAC41-20-270).
  2. Disinfection of Tools
    • Each student or instructor must have a wet disinfection unit at their station for sterilizing reusable tools (e.g., combs, shears) after each use. Disinfectants must be EPA-registered and bactericidal, virucidal, and fungicidal.
    • Single-use items (e.g., razor blades) must be discarded after each client in a labeled sharps container.
  3. Hand Hygiene
    • Practitioners must wash hands with soap and water or use hand sanitizer before services (e.g., Texas Rule 83.102).
  4. Client Protection
    • Sanitary neck strips or towels must be used to prevent capes from contacting clients’ skin directly (e.g., California regulations).
    • Services cannot be performed on inflamed, broken, or infected skin, and practitioners with such conditions on their hands must wear gloves.
  5. Product Safety
    • Cosmetic products containing FDA-banned hazardous substances are prohibited, and all products must be used per manufacturer instructions (e.g., Virginia’s 18VAC41-20-270).
  6. Waste Management
    • Proper disposal of soiled items (e.g., hair clippings) and hazardous waste (e.g., blades) is required, often daily or after each client.
  7. Health Department Compliance
    • Schools must follow state health department guidelines and report inspection results (e.g., Virginia requires reporting to the Board of Barbers and Cosmetology).
  8. Self-Inspection
    • Annual self-inspections must be documented and retained for review (e.g., Virginia mandates keeping records for five years).


Discussion

  • State-Specific Variations: Always consult your state’s barbering or cosmetology board for exact requirements. For instance, Texas (TDLR) emphasizes signage and licensing display, while California focuses on detailed sterilization methods.
  • Inspections: Schools are subject to regular inspections by state boards or health departments to ensure compliance.

Lakeland Florida high school offers free clothes and laundry facilities. Expansion of this concept to Saturdays for all students in the district would contribute to greater utilization of square footage that is normally unused. It may also lower energy cost and contribute to “family feeling” in the district.

Big Brother is watching you.”

“Always the eyes watching you and the voice enveloping you. Asleep or awake, working or eating, indoors or out of doors, in the bath or in bed—no escape. Nothing was your own except the few cubic centimeters in your skull.”

“At any rate, they could plug in your wire whenever they wanted to. You had to live—did live, from habit that became instinct—in the assumption that every sound you made was overheard, and, except in darkness, every movement scrutinized.”

“It was terribly dangerous to let your thoughts wander when you were in any public place or within range of a telescreen. The smallest thing could give you away.”

“Fire at Full Moon” 1933 | Paul Klee

Hard upon conclusion of the fall semester, educational settlements ebb in population as students return to their home fires.

Today we pull together best practice in the systems — the people and the technologies — that sustain campus safety and stability during the Thanksgiving, Christmas and New Year holidays.

Educational and Day-Care Occupancies (July 23, 2025 Second Draft Transcript)

The Life Safety Code addresses those construction, protection, and occupancy features necessary to minimize danger to life from the effects of fire, including smoke, heat, and toxic gases created during a fire.   It is widely incorporated by reference into public safety statutes; typically coupled with the consensus products of the International Code Council.   It is a mighty document — one of the NFPA’s leading titles — so we deal with it in pieces; consulting it for decisions to be made for the following:

(1) Determination of the occupancy classification in Chapters 12 through 42.

(2) Determination of whether a building or structure is new or existing.

(3) Determination of the occupant load.

(4) Determination of the hazard of contents.

There are emergent issues — such as active shooter response, integration of life and fire safety systems on the internet of small things — and recurrent issues such as excessive rehabilitation and conformity criteria and the ever-expanding requirements for sprinklers and portable fire extinguishers with which to reckon.  It is never easy telling a safety professional paid to make a market for his product or service that it is impossible to be alive and safe.  It is even harder telling the dean of a department how much it will cost to bring the square-footage under his stewardship up to the current code.

The 2021 edition is the current edition and is accessible below:

NFPA 101 Life Safety Code Free Public Access

Public input on the 2027 Revision will be received until June 4, 2024.  Public comment on the Second Draft 2027 Revision will be received until March 31, 2026.

 

Since the Life Safety Code is one of the most “living” of living documents — the International Building Code and the National Electric Code also move continuously — we can start anywhere and anytime and still make meaningful contributions to it.   We have been advocating in this document since the 2003 edition in which we submitted proposals for changes such as:

• A student residence facility life safety crosswalk between NFPA 101 and the International Building Code

• Refinements to Chapters 14 and 15 covering education facilities (with particular attention to door technologies)

• Identification of an ingress path for rescue and recovery personnel toward electric service equipment installations.

• Risk-informed requirement for installation of grab bars in bathing areas

• Modification of the 90-minute emergency lighting requirements rule for small buildings and for fixed interval testing

• Modification of emergency illumination fixed interval testing

• Table 7.3.1 Occupant Load revisions

• Harmonization of egress path width with European building codes

There are others.  It is typically difficult to make changes to stabilized standard though some of the concepts were integrated by the committee into other parts of the NFPA 101 in unexpected, though productive, ways.  Example transcripts of proposed 2023 revisions to the education facility chapter is linked below:

Chapter 14 Public Input Report: New Educational Occupancies

Educational and Day Care Occupancies: Second Draft Public Comments with Responses Report

Since NFPA 101 is so vast in its implications we list a few of the sections we track, and can drill into further, according to client interest:

Chapter 3: Definitions

Chapter 7: Means of Egress

Chapter 12: New Assembly Occupancies

Chapter 13: Existing Assembly Occupancies

Chapter 16 Public Input Report: New Day-Care Facilities

Chapter 17 Public Input Report: Existing Day Care Facilities

Chapter 18 Public Input Report: New Health Care Facilities

Chapter 19 Public Input Report: Existing Health Care Facilities

Chapter 28: Public Input Report: New Hotels and Dormitories

Chapter 29: Public Input Report: Existing Hotels and Dormitories

Chapter 43: Building Rehabilitation

Annex A: Explanatory Material

As always we encourage front-line staff, facility managers, subject matter experts and trade associations to participate directly in the NFPA code development process (CLICK HERE to get started)

NFPA 101 is a cross-cutting title so we maintain it on the agenda of our several colloquia —Housing, Prometheus, Security and Pathways colloquia.  See our CALENDAR for the next online meeting; open to everyone.
