Wet film thickness testing (WFTT)

Assess Monitor Control

The Association of British Insurers (ABI) statistics indicate that an estimated 70% of fires that occur in commercial kitchens throughout the United Kingdom each year have the cause identified and attributed to the grease extract ventilation system.

Insurers may not always settle a potentially substantial claim for loss or damage if the extract system is found to be the cause of the fire and particularly if it can be demonstrated that the system was not regularly and competently cleaned and maintained in accordance with the BESA specification TR19® Grease requirements to comply with their buildings insurance policy conditions or warranties.

Why?

Assessing system conditions, monitoring deposit levels and controlling their build up is essential to maintain hygiene standards and minimise fire risks in grease extract ventilation systems in accordance with the Building Engineering Services Association (BESA) specification TR19® Grease - Fire Risk Management of Grease Accumulation within Kitchen Extraction Systems standards of cleanliness requirements and should be considered an integral aspect of any cleaning and maintenance programme.
How?

Our competent, experienced and knowledgeable technicians, utilise the latest innovative methods, specialist equipment and chemicals to effectively remove all contaminants including accumulated grease, dirt and food debris that might otherwise compromise the integrity, performance and efficiency of the kitchen environment.
While undertaking the work we ensure that all health and safety requirements such as the Control of Substances Hazardous to Health (COSHH) Regulations 2002 (SI 2002/2677) and Personal Protective Equipment (PPE) Regulations 2002 (SI 2002/1144) are strictly always adhered to.

What?

Wet Film Thickness Testing (WFTT) is a technique that is used to accurately assess the level of grease and soft deposit build-up within ventilation ductwork. This testing provides an objective, repeatable and quantifiable method of measuring the degree of grease deposit levels and supports the possible subjectivity of a visual inspection alone. In turn these measurements will help to determine when and how frequently cleaning is required to keep your grease extract ventilation system safe and compliant.
When?

The regular periodic cleaning and decontamination of the grease extract ventilation system is essential due to the high fire risk and hygiene implications typically associated with this type of installation, which could otherwise pose a serious fire hazard within your kitchen environment.
At a minimum, cleaning of such systems should be undertaken on an annual basis, however, many systems will require a higher frequency of cleaning dependent on a combination of critical factors such as the number days and hours in operation per week, type of cuisine, volume of catering taking place and even location.
Once a cleaning schedule has begun, pre and post clean Wet Film Thickness Testing (WFTT) together with visual assessments help to determine how frequently an extract system must be cleaned.
Once a system is TR19® Grease compliant, it has been found that average total High Risk Combustion Load Levels (HR-CLLs) can be reduced by up to 83%.
