Fire Safety in Dental Practices: What the Law Requires and Where Practices Get Caught Out

Fire safety in a dental practice is not a box to tick once and file away. It is an ongoing legal obligation with two distinct enforcement bodies, a mandatory documentation requirement from CQC that now applies before registration is granted, and a physical reality that inspectors check on the day of visit — not from the policy folder.

The Regulatory Reform (Fire Safety) Order 2005 (RRO) is the primary legislation. It replaced over 70 pieces of fire safety law and introduced a single, premises-based framework. Under Article 9 of the RRO, every responsible person — typically the registered provider or the practice owner — must carry out a suitable and sufficient fire risk assessment, implement any measures needed, record the findings, and review the assessment regularly. The local Fire and Rescue Authority enforces the RRO. CQC uses the same assessment as evidence under its Safe key question.

From 9 February 2026, dental practices must submit a current fire risk assessment before CQC registration is granted. The RRO applies to all non-domestic premises — enforcement can result in prohibition notices that close the practice immediately. Clinical waste, medical gas cylinders, and sedation equipment all create specific fire load considerations that standard commercial fire risk assessments do not cover.

What Makes a Dental Practice Fire Risk Different from a Standard Commercial Premises?

Dental practices carry fire risks that generic commercial fire risk assessment templates are not designed to capture. A competent assessor carrying out a dental fire risk assessment must understand and assess the following dental-specific risk factors:

• Clinical waste storage — yellow-lidded and orange-lidded clinical waste bags have specific storage requirements that affect fire load and fire spread risk. Dental clinical waste awaiting collection must be stored in a designated area that does not obstruct escape routes.
• Medical gas cylinders — nitrous oxide and oxygen cylinders present an explosion and accelerant risk if exposed to heat. Storage must comply with BCGA (British Compressed Gases Association) guidance and be considered in the fire risk assessment.
• Autoclaves and decontamination equipment — high-temperature equipment creates ignition risk if positioned incorrectly or if electrical faults develop.
• Sedation agents and compressed gas tubing — dental sedation equipment including inhalation and IV sedation apparatus must be factored into the assessment.
• Patient evacuation — patients in dental chairs under sedation, or in mid-treatment, have limited mobility. The evacuation plan must specifically address chair-bound patients and the number of clinical staff required to assist.

What Must a Dental Practice Fire Risk Assessment Cover?

Article 9 of the RRO requires the assessment to be suitable and sufficient for the specific premises. For a dental practice, this means the assessment must be carried out by a person who is competent — someone with sufficient training and experience to understand dental-specific hazards. A generic online template is not sufficient. CQC inspectors are trained to identify template-based assessments that have not been customised to the actual premises.

1. Identification of fire hazards — ignition sources, fuel sources (including clinical materials), and oxygen sources including medical gas systems
2. Identification of people at risk — patients (particularly those with mobility limitations or under sedation), staff, and visitors
3. Evaluation of the risk — assessing the likelihood and consequence of fire, and whether existing controls are adequate
4. Removal and reduction measures — actions to reduce risk to as low as reasonably practicable
5. Record of findings and actions — the written assessment document, with named responsible persons and completion dates for each action
6. Review schedule — a commitment to review the assessment at a defined interval or after any significant change

What Physical Fire Safety Standards Must the Premises Meet?

Beyond the risk assessment document, inspectors — whether from CQC or the Fire and Rescue Authority — check the physical state of the premises against the findings and actions in the assessment. Common failure points in dental practice fire safety inspections include:

• Fire doors not self-closing — door closers that are faulty, have been removed, or are held open with wedges are the single most common physical fire safety failure in healthcare premises
• Emergency lighting not tested or not functioning — emergency lighting must be tested monthly (function test) and annually (full discharge test), with a signed log of every test
• Fire extinguisher service overdue — extinguishers must be annually serviced by a competent engineer, with a service tag and record
• Escape routes obstructed — corridors and exit routes used as storage areas, particularly in small practices where storage space is limited
• Fire safety signs missing or incorrectly placed — exit signs, assembly point signs, and equipment location signs that are absent or obscured

When Does the Fire Risk Assessment Need to Be Reviewed?

The RRO requires the responsible person to review the assessment regularly and whenever there is reason to suspect it is no longer valid or there has been a significant change to the premises or its use. For a dental practice, this includes: any refurbishment or alteration to the layout; a change in the use of any room (e.g., a new sedation suite); the addition of new medical gas equipment; a change in the patient population served; and any fire incident, however minor. For CQC purposes, an assessment that has not been reviewed in the last 12 months — even with no apparent changes — is likely to be flagged as overdue.
