Cleaning of Extract ductwork and Extract fans on Rooftop plant and Plant rooms

  • General Note: Operatives should be reminded of the risks and hazards associated with working at height and in plant rooms, e.g., no work should be undertaken on rooftop equipment unless appropriate edge or fall protection devices (Body Harnesses/Safety nets) have been installed. Plant/machinery rooms have confined spaces and that head height can be very limited, with ducting and other plant and equipment protruding. Ducting can be fragile, have sharp edges or screws or bolts that can protrude.

Plant Room Cleaning

  • The Team Leader (Supervisor/Forman) has to ensure that a ‘Permit to work’ is issued, that it is read, understood and signed by those undertaking the task. A drawing or blueprint of the rooftop ducting and plant room must be attached to the ‘permit’. Also. If needed, make sure that all keys to roof access doors and plant room are signed for.
  • The Team Leader is to check that all equipment sited below roof level and in the plant, the room is switched off and all controls isolated.

Roof Operations

  • Team Lead to climb up on to the roof systems using a ladder or step ladder to gain access and carry out a survey to determine if access panels need to be cut and inserted. 
  • Note: team leader to determine the safe climbing route also if the rooftop is fitted with edge or fall protection devices.
  • Once the Team Leader has determined that the area is safe to work on, they will instruct the operatives of where access panels are to be inserted.
  • The Operatives will then climb onto the structure and if required will attach their inertia safety line to the nearest safety eyebolt or latch way system.
  • The Operatives will cut panels as required and insert the new access panels while cleaning areas as necessary.

Ductwork Cleaning – Installation of Access Panels 

  • Operatives to erect access equipment e.g. stepladders or ladders correctly and safely. Ladders to be erected at the correct angle of 1:4 (75 Degree). If working between 2-6 meters in height ladders must be footed or an approved ladder stopper or stabilizer used.

  • The door’s retaining frame is used as a template and marked on the side of the ductwork. If there is insulation around the outside of the ductwork, this should be cut away leaving a 3 cm edge around where the door will be positioned before marking the door frame on the duct.
  • Using a cone drill the operatives are to drill holes in the corners of the door template.
  • For rectangular ductwork, the operative will use a Draco metal shear to trace along the edge of the template. Operatives are reminded that the edges of ductwork can be sharp and can sometimes be hot after cutting.
  • For spiral / curved duct the operative performs the same procedure but using a Jigsaw.
  • The tangs of the door frame are inserted into the cut hole and the tangs are then bent over to fit the frame into place. Mole grips are then used to crimp the tangs and secure the door frame into place. Note: make sure that the neoprene seal is compressed to form an airtight seal.
  • Any cut away insulation should be taped up to prevent migration of fibres. Other types of ductwork insulation may require various types of insulation cover. These are to be discussed and organised by the customer.

Sheeting up Areas

  • General Note: All working areas and their surrounding areas have a chance of becoming contaminated with the dirt of dust and will require protection. This is achieved by sheeting over the area.
  • The Team Leader is to discuss the area to be sheeted up with the site contact. All valuables and personal items are to be removed by the site contact.
  • Operatives are to make sure that polythene sheeting is clean before use to prevent dirt from being transferred to a clean area.
  • Operatives are to be careful when sheeting up to make sure that the polythene sheet does not catch on any equipment. Caught sheeting has the potential to pull items off of tables.
  • When covering electrical equipment that cannot be switched off, operatives are to make small air holes to allow cooling.
  • After cleaning works have finished, or at the end of each shift, the sheeting will be removed by the Operatives. All furnishings (chairs and desks etc.…) should be returned to their original positions.
