Sauna risk assessment

Sauna risk assessment is the systematic audit behind every safe sauna — the documented identification of the cabin's hazards, the judgement of their likelihood and severity, and the controls that bring each to an acceptable level. In a commercial or workplace setting the risk assessment is a legal and professional obligation with a standard methodology; in the private cabin it is the same thinking, carried in the household maintenance calendar and the family's rules rather than in a folder. This article describes the method, provides the sauna's hazard register and links every item to its encyclopaedia page.

The method

Risk assessment proceeds in the five steps taught everywhere from health-and-safety to fire-safety practice: identify the hazards; decide who might be harmed and how; evaluate the risk (likelihood and severity) and decide on controls; record the findings; and review the assessment at regular intervals or whenever something changes — a new heater, a new user group, an incident, a season (see Sauna incident reporting). The legal status of the document depends on jurisdiction and setting — the workplace's obligations under the occupational-health rules of its country, the building's under the fire-safety regulations (see Fire safety regulations for saunas), the facility's under the operator's own duty of care — and this article's role is the technical content, not the compliance advice of a particular territory (see Workplace safety for sauna staff).

The sauna's hazard register

The cabin's hazards, with their controls, constitute the register that the assessment checks line by line:

• Thermal hazards: the stove and stones (burns — controlled by clearances, guards, Burn prevention in a sauna, supervision), the overheated room (heat illness — controlled by thermostat, temperature, session controls, staff watch), and hot glass and wood (see Safety glass in a sauna, Sauna burns).
• Fire and electrical hazards: ignition of structure or laundry (Sauna fire safety, Sauna electrical safety, Sauna heater inspection), chimney and ash (Sauna chimney inspection, Disposing of sauna ash), carbon monoxide (Carbon monoxide poisoning in a sauna), detection and suppression (Sauna fire detection, Fire extinguisher for a sauna, Sauna emergency shut-off).
• Slip, trip and fall hazards: wet floors, thresholds and changes of level (Slip and fall hazards in a sauna, Sauna floor, Sauna floor drain), with the vasodilated bather as a contributing harm factor.
• Hygiene and infection hazards: shared cabins, benches, floors and water (Sauna hygiene, Cleaning a sauna, Commercial sauna cleaning, Infection and sauna, Microbiology of a sauna).
• Structure and access: the cabin's own condition, doors and glass (Sauna construction, Sauna door opening direction, Safety glass in a sauna), outdoor-cabin winter and moisture issues (Winterising an outdoor sauna, Condensation in a sauna).
• User-group hazards: children, older adults, pregnancy, chronic illness, lone bathers (Child safety in a sauna, Older adults and sauna, Going to a sauna alone, Sauna contraindications).

For each line the assessment names the people at risk (staff, public, the family's children, maintenance personnel), the current controls, and the residual risk — and the maintenance schedule, the staff training and the supervision round (Sauna supervision, Sauna maintenance schedule) are the controls that make the residual risks small.

The review rhythm

The rhythm of the review is the discipline's real content: annually for the ordinary facility, after every incident (Sauna incident reporting), after every change of equipment, and at the change of season where the cabin is an outdoor one; the private owner's rhythm is the same calendar as the chimney sweep and the heater inspection — the risk assessment that lives only in the folder is paper; the one that has its hazards closed is the cabin (see Sauna safety, Wellness emergency plan and Sauna evacuation plan).
