SanPiN 5804-91 PDF

Full title and description

SanPiN 5804-91 — "Санитарные нормы и правила устройства и эксплуатации лазеров" (Sanitary norms and rules for the design and operation of lasers). The document establishes hygienic and radiation-safety requirements for laser equipment, defines classification by hazard, sets maximum permissible exposure levels (MPE/PDU) across a broad wavelength range and specifies engineering, organizational and medical measures for safe design and operation of laser installations.

Abstract

This SanPiN (No. 5804-91), approved 31 July 1991, provides mandatory rules for enterprises and organizations that design, manufacture or operate laser devices. It defines: permissible exposure limits for laser radiation (in the range ~180 nm to 10^5 nm), a laser-classification scheme by hazard, requirements for protective design (interlocks, enclosures, warning signals), workplace layout, personnel training and medical surveillance, and measurement/dosimetry methods for assessing hazard zones. The rules were prepared using prior SanPiN 2392-81 and IEC laser safety guidance.

• Edition / version: 1991 edition (SanPiN designation 5804-91; replaces SanPiN 2392-81).
• Number of pages: Typical published copies list ~84 pages (A5-format reprints/collections).

Scope

Scope covers hygienic and safety requirements for the design, installation and operation of laser devices and laser installations across industrial, research, medical and other settings. The rules set maximum permissible levels of laser radiation for different exposure conditions, classify lasers by hazard class, require appropriate protective engineering controls (enclosures, interlocks, shutters), administrative controls (signage, restricted access, training) and personal protective equipment (PPE), and mandate measurement, dosimetry and medical control procedures. They apply to enterprises and organizations that design, manufacture or operate laser equipment.

Key topics and requirements

• Definition of terms and classification of laser products by hazard class (for safe-use categorization).
• Maximum permissible exposure (MPE / PDU) values for multiple wavelength regions and exposure durations.
• Engineering safety measures: enclosures, protective housings, beam stops, interlocks, apertures and emission-limiting devices.
• Administrative controls: zone designation (laser-hazard zones), access control, warning signs, operating procedures and personnel training/competency requirements.
• Personal protective measures: requirements for eye and skin protection, optical filters and selection guidance.
• Measurement and dosimetry: methods for assessing irradiance/energy, defining laser-safe distances and verifying compliance with MPEs.
• Occupational health provisions: medical examinations, recordkeeping and surveillance for personnel working with hazardous laser classes.
• Guidance for special applications (medical lasers, fiber-optic delivery systems, pulsed vs. continuous-wave systems) and handling of secondary hazards (UV, IR, X-ray, electrical, thermal, chemical by-products).

Typical use and users

Used historically by employers, safety engineers, designers and operators of laser equipment in industry, research laboratories, medical facilities, military and educational institutions to ensure compliance with state sanitary and radiation-safety requirements. Also used by occupational health professionals, regulatory bodies and certification/test laboratories for hazard assessment and workplace control planning.

Related standards

Directly references and was developed taking into account earlier SanPiN 2392-81 and international IEC laser safety guidance (IEC publication 825, later evolved into the IEC 60825 series). Modern equivalents and international counterparts include IEC 60825 (safety of laser products) and national laser-safety standards (for example, ANSI Z136 series in the USA). When implementing contemporary laser-safety programs, refer to current national/regional regulations and the latest IEC/ISO documents.

FAQ

Q: What is this standard?

A: SanPiN 5804-91 is a Soviet-era sanitary regulation — "Sanitary norms and rules for the design and operation of lasers" — that defined laser-radiation MPEs, classification and safety requirements for design and operation of laser equipment.

Q: What does it cover?

A: It covers permissible exposure limits across wide wavelength ranges, classification of lasers by hazard, engineering and administrative safety measures (enclosures, interlocks, warning signs), PPE selection, measurement/dosimetry methods, workplace layout and medical surveillance.

Q: Who typically uses it?

A: Historically used by equipment designers, employers, safety officers, occupational health services, test laboratories and regulatory inspectors in organizations operating lasers (industry, research, medicine, education, military). Modern users should map its requirements to current national/international standards and local law.

Q: Is it current or superseded?

A: The SanPiN 5804-91 text itself dates from 1991. In the Russian Federation it has been recognized as not effective following regulatory actions in 2020; contemporary laser safety practice should follow current national sanitary rules and the up-to-date IEC/ISO or national standards (for example, the IEC 60825 series and applicable national transpositions). Always check the current regulatory status in your jurisdiction before relying on an older text.

Q: Is it part of a series?

A: Yes — it is part of the SanPiN (sanitary norms and rules) system of regulatory documents (this edition replaced earlier SanPiN 2392-81 for lasers). It also references international IEC guidance (publication 825 / later IEC 60825 series).

Q: What are the key keywords?

A: Laser, laser safety, SanPiN, MPE/PDU, classification, dosimetry, interlocks, protective eyewear, Minzdrav USSR, occupational health.
