1 Access Panels & Hatches

2 Access Panels & Hatches General Information Terminology The term Panel or Panels describes wall or ceiling access panels that are used for periodic maintenance or repairs and are mechanically fixed into position. The term Hatch or Hatches is applied to wall or ceiling access hatches that are in regular use and are either hinged or screw fixed. System Introduction Access panels and hatches are common and essential elements used for carrying out daily maintenance in buildings and inspection routine to most E&M services within building compartments. Depending on the location, some of these will require small openings, typically 600mm x 600mm, while some areas may require larger openings, e.g. the size of a single or double leaf doorset. Promat access panels and hatches are approved in a range of sizes and fire resistance, offering flexibility for any type of opening in substrates such as walls, floors or ceilings. They are easy to install and can be finished or decorated to suit the surrounding building elements. The types of fixing for these panels and hatches largely depends on the area of application, frequency of carrying out maintenance, appearance and the weight of the panels/hatches. Common in most applications, hinged hatches are usually prefabricated in a standard size of 600mm x 600mm. They can also be custom-made to specified dimensions, depending on size and quantity. Safety chains are fitted to all panels exceeding 450mm x 450mm in size. Preformed holes in all four sides of the frame are positioned to match wall and ceiling metal structures for secure screw fixing of the panel to the structures. Screw-fixed panels can be fabricated in-situ and offer ideal flexibility when used in conjunction with Promat fire resistant partitions or ceiling systems. Note: installed access panels or hatches should have a fire resistance at least equal to the surrounding structural elements. The structural elements can be of masonry or concrete, drywall partition, suspended ceiling etc. Care should also be taken to ensure any gaps between the panel/hatch and the aperture are thoroughly sealed to prevent the passage of hot or cold smoke or gases. Fire Testing Methods Fire resistance testing for Promat access panels or hatches is conducted to either Australian Standard AS1530: Part 4 or British Standard BS476: Part 20 & 22. However, DIN 4102 has been considered in some instances. The test specimen is heated in the manner prescribed within the standard until the failure criteria have been reached. The time to reach the failure criteria are represented by performance measurements, referred to as Fire Resistance Levels (FRL). 1. Structural Adequacy (Stability) Failure is deemed to have occurred when either: (a) collapse occurs, or (b) the deflection or rate of deflection occurs which is in excess of that specified in the standard and is applicable to the element under test. NOTE: These criteria are generally only applicable to load bearing elements although (a) can in some circumstances apply to panels and hatches. 2. Integrity The ability of a specimen of a separating element to contain a fire to specified criteria free from collapse, holes, cracks or fissures and sustained flaming on the unexposed face. 3. Insulation Failure is deemed to have occurred when either: (a) the average temperature on the unexposed face of the specimen increases by more than 140 C above the initial temperature, or (b) the temperature at any point on the unexposed face increases by more than 180 C above the initial temperature. Finishing Once installed, Promat access panels or hatches may be painted, subject to end user preference. It is recommended that the paint used should be a water-based paint, e.g. emulsion paint. If necessary, the surface of access panels or hatches can be decorated using wall paper or proprietary decorative tiling. Fixing In order to avoid cutting furring channels or installing metal studs at 450mm or 600mm centres, the use of panel sizes somewhere between these dimensions is recommended. When a hinged access panel or hatch is installed on a wall, it is important to always place the hinge arrangement at bottom of the penetration, not at the side. This will prevents the panel from falling out of the wall because the locks at the top of the panel hold it in place and hinges at the bottom are not exposed to frequent or prolonged pulling stress. 2
