Evaluating Fire Risks in the Workplace: The Basics

Fire safety is an important consideration for every business, but fire risks in the workplace can look very different depending on the premises. An office full of computers presents different hazards from a commercial kitchen. A warehouse storing large quantities of materials needs a different approach again.

For businesses, the starting point for evaluating fire risks is understanding where a fire could begin, how it might spread and who could be put at risk. Appropriate precautions can be introduced and maintained.

What Are Common Fire Risks in the Workplace?

Most workplaces contain several potential sources of fire. Electrical equipment and wiring can create a risk if they become damaged or develop faults. Portable heaters and other heat-producing equipment require careful positioning and use.

Combustible materials also need consideration. Paper and cardboard may be common in offices, while warehouses and industrial premises could contain packaging, chemicals, fuels or large quantities of stock.

People themselves can contribute to risk too. Poor housekeeping, blocked escape routes and equipment being used incorrectly can all make fires more likely or increase their consequences.

Offices and Commercial Buildings

Offices may appear relatively low risk, but modern workplaces contain plenty of electrical equipment. Computers, monitors, kitchen appliances, extension leads and charging devices are often used throughout the day.

Businesses should ensure electrical equipment is properly maintained and avoid overloading sockets. Escape routes need to remain clear, while fire alarms, emergency lighting and extinguishers should be checked and serviced as required.

Larger commercial buildings may also require effective fire stopping to help prevent flames and smoke travelling through walls, floors and other parts of the property.

Kitchens, Restaurants and Hotels

Commercial kitchens have a very different risk profile. Cooking equipment produces significant heat. Oils, fats and grease deposits can provide fuel for a fire.

Extraction systems should be cleaned and maintained, and cooking equipment needs appropriate servicing. Staff should also understand what to do if a fire occurs and know where emergency exits are located.

Hotels have the additional challenge of protecting guests who may be unfamiliar with the building, making clear escape routes, effective alarms and suitable fire doors particularly important.

Warehouses and Industrial Premises

Warehouses can contain significant quantities of combustible materials in one place. Packaging and stored products can potentially allow a fire to grow and spread rapidly.

Industrial sites may have additional hazards from machinery, hot work, manufacturing processes or particular substances used on-site.

Good housekeeping and sensible storage are therefore particularly important, but businesses also need to consider how a fire could travel through a large building and whether existing fire protection measures remain suitable.

Start With a Fire Risk Assessment

Businesses should not rely on assumptions about where their biggest risks lie. A fire risk assessment provides a structured way to identify hazards, establish who may be at risk and assess whether existing precautions are adequate.

Most non-domestic premises in England and Wales are required to have a suitable and sufficient fire risk assessment. Responsibility ultimately sits with the Responsible Person, although a competent fire safety professional can be appointed to carry out the assessment.

The assessment should also be reviewed rather than simply completed and forgotten. Changes to the premises, working practices, equipment or number of occupants can introduce new risks.

Reducing the Risk of Fire Spreading

Preventing fires is only one part of workplace fire safety. Businesses also need measures designed to limit the consequences if one does occur.

Fire stopping is an important example. Openings and gaps around pipes and other services can compromise fire-resistant walls and floors, potentially allowing smoke and flames to move between areas of a building.

Appropriate fire stopping helps maintain compartmentation, slowing the spread of fire and providing valuable time for people to evacuate.

Getting Professional Fire Safety Support

Evaluating fire risks in the workplace requires businesses to consider the building as a whole. The hazards themselves, the people using the premises, escape routes, detection systems and measures designed to limit fire spread all form part of the picture.

Robinsons Facilities Services can support businesses with professional fire risk assessments as well as fire stopping and other fire safety services. Regularly reviewing these measures helps businesses identify weaknesses and provide a safer environment for employees and visitors.
