About Course

Laser safety certificate for cold or hot laser therapy
This BMLA-approved online laser safety training course gives healthcare and veterinary professionals the essential knowledge required to use Class 3B (cold/LLLT) and Class 4 (hot) Laser Therapy devices safely, confidently, and in full compliance with UK and EU legislation.

This course has been approved by the British Medical Laser Association, and follows the Core of Knowledge syllabus recommended for clinical laser users. It specifically covers Laser Therapy lasers and the hazards associated with their use in therapeutic settings.

Appropriate laser safety training is a requirement under Health and Safety legislation, and this course provides that training for professionals in physiotherapy, chiropractic care, veterinary practice, and lactation consultancy.

You’ll learn about laser physics, tissue interactions, CE marking, risk controls, and PPE – all contextualised to real-world clinical use. Upon completion, you’ll receive a recognised laser safety certificate online.

Built with flexibility in mind, this self-paced laser therapy training course takes approximately 3 hours to complete. Each module includes short quizzes to support knowledge retention and practical understanding.

This course bridges the gap between generic safety training and the real needs of clinical and healthcare Laser Therapy users. It’s designed to support your professional responsibilities, protect your patients, and help you practise with clarity and confidence.

Course Content

Part 1: Laser generation and diode laser technology
In this first part of the course, we’ll start with the foundational physics of light and what makes laser light unique compared to other types of optical energy. You’ll learn how therapeutic lasers generate red and infrared light, and how diode laser systems produce and control emission. We’ll then explore key emission characteristics like power, wavelength, and fluence — and how they affect the way light behaves in a clinical setting. Finally, we’ll cover how laser light interacts with tissue, including the mechanisms behind photobiomodulation (PBM), selective absorption, and penetration depth in therapeutic applications.

  • Section 1.1: Introduction to laser physics and laser generation
    19:13
  • Section 1.1: Knowledge Check Questions
  • Section 1.2: Laser diode technology, and emission characteristics
    15:45
  • Section 1.2: Knowledge Check Questions
  • Section 1.3: Laser-tissue interaction, including penetration of light of different wavelengths through skin and eyes
    13:51
  • Section 1.3: Knowledge Check Questions

Part 2: Hazards of lasers, standards and the engineering controls
n this section, you’ll learn how and where laser light can cause harm — and why the eyes are more vulnerable than skin to injury. We’ll cover the types of hazards associated with therapeutic laser use, including direct exposure, reflections, and non-beam risks like heat and electrical safety. You’ll also be introduced to the relevant international standards for laser safety, including CE marking and the laser classification system used for Class 3B and Class 4 devices. Finally, we’ll look at the engineering controls built into your laser system — such as emission indicators, key switches, and interlocks — and how these contribute to safe operation in a clinical environment.

Part 3: Legislation, administration controls, and personal protection equipment
In this final part of the course, you’ll learn what’s meant by Exposure Limit Values (ELVs) and Maximum Permissible Exposure (MPE) — including where these limits are defined, how they must be complied with, and how they’re used to calculate the Nominal Ocular Hazard Distance (NOHD). We’ll also cover the importance of establishing a Laser Controlled Area, using appropriate laser protective eyewear, and implementing risk-reduction measures tailored to therapeutic laser use. You’ll be introduced to the key health and safety legislation applicable in Ireland, the UK, and the EU, and what’s required under these frameworks. Finally, we’ll explore the components of a compliant laser safety programme — including defined roles and responsibilities, the creation and use of Local Rules, and the documentation and procedures that support best-practice laser use in clinical settings.
