The introduction of legislation Grease Extract Guidance in 2019 (BESA’s TR19), requiring premises to have their entire ventilation system cleaned every three to 12 months, has presented many companies with a headache.
According to ventilation, maintenance and hygiene company, System Hygienics, risers are notoriously difficult to access, inspect and maintain.
Risers are generally positioned in the centre of a building or are bolted on to an exterior wall at a height, or in a place which can only be reached by treacherously navigating the roof.
Cleaning of risers ensures compliance with legislation and insurance requirements, and protects the health and safety of employees and others within the building.
It also potentially protects those in adjacent offices or accommodation near to where the ventilation is positioned.
System Hygienics has introduced a method to tackle these generally inaccessible areas.
Hot chemical viscosity riser cleaning
The process involves pumping a heated solution of diluted chemical down into the riser and then extracting it at the bottom when it has efficiently cut through grease and dirt.
System Hygienics ensures safety is a priority throughout the procedure, cordoning off the entire area and collecting all ‘used’ chemicals by vacuum before removing them from site.
Even where roof access is not possible or is deemed unsafe, they're able to reach the highest riser discharge point by using a portable, compact lift, eliminating the need to erect scaffolding or introduce any form of harness work.
The process is carried out with minimal disruption and provides proven results which confidently meet the legislative requirements.
An important addition to the System Hygienics commitment to clean air
Already having a well-respected reputation for our BESA-approved cleaning and testing solutions, the company's customers had become accustomed to relying upon their expertise to handle all aspects of ductwork, ventilation and fire damper maintenance and testing.
The ability to offer a solution for this additional, historically problematic area has allowed them to offer complete compliance without the need for third party involvement.
Owner and Managing Director, Mark Poultney, said: “This service is something we are proud to shout about. Here at System Hygienics we are always looking for the next solution to help our clients adhere to legislation, and to ensure their premises is safe to operate.
"Risers have always been a challenging area to clean but where there’s a challenge there’s an innovation we’re yet to discover, as demonstrated!”
