Examples of such equipment are sensory swings, adaptive seating, retractable projector screens, foldable mats, and therapy tools.Note 3: Multi-purpose rooms should incorporate technology and assistive features to enhance accessibility. This includes, but is not limited to, assistive listening devices (e.g., hearing loops, FM systems, or other wireless technology) for children who are hard of hearing, as well as other forms of assistive technology (e.g., AAC devices, tactile output devices, adaptive switches). Voice-controlled or touchless controls for lighting, temperature, and sound adjustments should also be considered to accommodate diverse needs.Note 4: Multi-purpose rooms should incorporate natural lighting where possible (e.g., by using windows) to create a well-lit environment. Glare control measures, such as blinds or curtains, should be considered to adjust brightness based on user needs and comfort.Note 5: Movable furniture should be equipped with at least two lockable casters.Note 6: In certain situations, consider adding multiple seating options.12.4.7 Multi-functional rooms
Multi-functional rooms are designed to support multiple activities simultaneously. Therefore, depending on their intended use, they shall comply with the most stringent requirements of the corresponding Clause 12.4.1 for classrooms and learning spaces, Clause 12.4.2 for therapy rooms, Clause 12.4.3 for music rooms, Clause 12.4.4 for sensory rooms, and Clause 12.4.6 for multi-purpose rooms.Note 1: A multi-functional room in a childcare centre is a flexible, adaptable space designed to accommodate a variety of activities and functions. It typically features an open layout, allowing it to be easily rearranged to suit different needs. This room can be used for group activities like arts and crafts, circle time, physical play, quiet reading, or as a space for special events or parent / guardian meetings.Note 2: Consider installing multiple anchoring points to allow for practical attachment and detachment of equipment without requiring significant time or effort. Examples of such equipment are sensory swings, adaptive seating, retractable projector screens, foldable mats, and therapy tools.Note 3: Multi-functional rooms should incorporate technology and assistive features to enhance accessibility. This includes, but is not limited to, assistive listening devices (e.g., hearing loops or FM systems) for children with hearing impairments, as well as other forms of assistive technology (e.g., AAC devices, tactile output devices, adaptive switches). Voice-controlled or touchless controls for lighting, temperature, and sound adjustments should also be considered to accommodate diverse needs.Note 4: Multi-functional rooms should incorporate natural lighting where possible (e.g. by using windows) to create a well-lit environment. Glare control measures, such as blinds or curtains, should be considered to adjust brightness based on user needs and comfort.12.4.8 Space and movement considerations
Spaces that are primarily designated for movement between adjacent rooms and spaces that are less than 1,800 mm in length shall:except as stated in item b) in this Clause below, comply with Clause 12.1.1 after the installation of all furniture, equipment, etc. (e.g., trash bins, office supply cabinets, mini fridges, etc.); orhave a minimum clear width of 1,600 mm.Note: A clear width dimension of 1,800 mm is preferred to allow multiple wheeled mobility device users (e.g., teacher and child) to navigate the hallways more easily.12.4.9 Access to learning areas, material, furniture and equipment
All learning areas, including all areas where equipment and toys for children are placed shall:be served by a path of travel that complies with Clause 12.1.1;have at least a stationary position clear space for two people in front of these areas or furniture that complies with Clause 12.1.2;have a turning diameter clear space of 2,100 mm in front of these areas or furniture;be within a forward or side reach of 500 mm and 900 mm above the finished floor with an obstruction of less than 250 mm;be illuminated to the same level as desks are required to be illuminated in CSA/ASC B651:23; andavoid sharp or exposed edges.12.4.9.1 Adjustable tables and desks
Tables and desks shall:have a top surface between 730 mm and 860 mm above the finished floor when they are intended for use by adults only;have a top surface between 400 mm and 730 mm when they are intended to be used by children only;be adjustable between 400 mm and at least 1,100 mm when they are intended to be used by both;have a knee clearance:width of at least 1,600 mm or the width of the table, whichever is less;depth of at least 480 mm;height of at least 685 mm or the height of the table surface minus 40 mm, whichever is less;have a minimum 30% Michelson luminance (colour) contrast with their surroundings complying with clause 4.2 of CSA/ASC B651:23; andinclude adjustment controls with a lock-out mechanism to prevent unintended movement during use.Note 1: Designing tables to accommodate both children and adults requires consideration of varying anthropometric metrics. A table should provide sufficient size and knee clearance to fit two wheeled mobility devices side by side, allowing an adult to assist a child. Additionally, children using wheeled mobility devices may require the same knee clearance and table height as adults due to the dimensions and seat elevation of their wheeled mobility devices, ensuring accessibility for both age groups. Therefore, the adjustable tables referenced in item c) of this Clause is the more versatile solution.Note 2: Comfort and functionality are important in both the scale and design of children’s furniture, as well as in planning the space as a work environment for adults. For children, tables with appropriate height, and chairs with suitable seating height allow children to use the table comfortably while keeping their feet on the ground. Children’s chairs should have shallow seats and slanted backs to support proper positioning.12.4.10 Family area (waiting, consultation, community, or event area)
Areas designated for families such as for waiting, consultations, or other purposes shall:comply with the requirements of Clause 12.4.6 when this area is in a multi-purpose room;comply with the requirements of Clause 12.4.7 when this area is in a multi-functional room;be served by a path of travel that complies with Clause 12.1.1;where provided, have seating that complies with clause 6.7.2 of CSA/ASC B651:23;have stationary clear space that complies with Clause 12.1.2 for a known number of staff but not less than 6 people; andhave a turning diameter clear space of 2,100 mm that does not overlap with at least one of the provided stationary clear spaces.Note 1: The family area should be designed to promote interaction between families and children. The internal environment should be arranged with consideration for children’s needs, ensuring that furniture and equipment do not obstruct navigation or hinder interaction.Note 2: Family areas do not necessarily need to be a separate space, they may be integrated into multi-purpose or multi-functional rooms.
