Installing fire resisting timber doorsets in the workplace Revision — ProQual Awarding Body Occupational Qualification
Interpret the given information relating to the work and resources when installing fire resisting timber doorsets, Maintain safe working practices when installing fire resisting timber doorsets, Select the required quantity and quality of resources for the methods of work to install fire resisting timber doorsets, Complete the work within the allocated time when installing fire resisting timber doorsets
Exam Tips
- Always cross-reference the site-specific information (e.g., drawings, specification) with the manufacturer's data sheet to ensure compatibility before starting work.
- During assessment, verbally explain your decisions regarding material selection and safe work procedures to demonstrate underpinning knowledge.
- Practice time management by planning the sequence of operations, including final checks like door swing, latch operation, and seal integrity tests.
- Create a detailed photographic or video evidence portfolio showing each stage of installation, including frame preparation, seal placement, and final door operation.
- Before starting work, cross-reference the door fire certificate with the project specification to confirm compatibility with the frame and ironmongery.
- Practice using a gap gauge to check perimeter clearances, and record measurements on a checklist that can be included as assessment evidence.
- Familiarize yourself with key British Standards (e.g., BS 8214:2016) and Building Regulations Approved Document B, as assessors look for evidence of legislative knowledge application.
- If unsure about any detail on-site, document how you consulted the supervisor or manufacturer’s technical support, demonstrating professional judgment and compliance with contract information.
Common Mistakes
- Misunderstanding the fire rating requirements or assuming all doorsets are fitted the same way without consulting the specific fire test evidence.
- Neglecting to check the condition of walls and openings before installation, leading to non-compliance due to inadequate structural support or gaps.
- Forgetting to allow for the expansion and operation of intumescent seals, e.g., by over-packing the frame or applying paint over seals.
- Using standard timber screws instead of fire-rated fixings, which can fail under fire conditions and compromise the door’s integrity.
- Failing to install intumescent seals or installing them incorrectly (e.g., missing grooves, wrong orientation), rendering the fire door ineffective.
- Ignoring the need for a bottom edge seal or threshold, allowing smoke to pass under the door and violating smoke control requirements.
Key Marking Points
- Award credit for correctly identifying and interpreting relevant information from risk assessments, method statements, and manufacturer's installation instructions.
- Observe and confirm the candidate selects appropriate tools, fixings, and sealants as per fire test evidence and specification.
- The installation must be square, plumb, and level within specified tolerances, with all intumescent and cold smoke seals correctly installed and the frame adequately packed and sealed to maintain fire integrity.
- Work should be completed within the allocated timeframe, with all waste materials disposed of safely and the work area left clean and tidy.
- Award credit for accurately interpreting door schedules and identifying the required fire resistance rating (e.g., FD30, FD60) and door dimensions from given information.
- Look for evidence of selecting correct fixings, seals (intumescent, cold smoke), and ironmongery that match the door’s fire certification and manufacturer’s instructions.
- Check that the candidate checks and adjusts the door frame for plumb and square before installation, clearing any obstructions or debris.
- Assess whether the candidate maintains the correct gaps (typically 3mm around sides and top, bottom gap as specified) to ensure intumescent seal activation and smoke sealing.
