... [Show More] Supervision
Accessibility
(Ans- Ensure that all playground equipment is equal access and wheelchair friendly. Complies with ADA and ASTM standard F1951 for wheelchair accessibility and propulsion.
Age Separation
(Ans- Pathways, landscaping, and playground equipment that caters to differing ages. Note - developmental differences that make this important
Sight Lines
(Ans- Layout of playground should minimize visual barriers so that caregivers can provide adequate supervision.
Conflicting Activities
(Ans- High motion and passive activities should not be placed next to each other. Slide exits should be kept away from other activities.
Signage
(Ans- Playgrounds should always include signs about age appropriate-ness for various equipment.
Supervision
(Ans- Caregivers should understand that supervision is a must on public playgrounds to help prevent injury.
Access and Egress (4)
(Ans- Ramps, Wide Stairway, Stepladder, Vertical Rung Ladder
Ramp
(Ans- Easiest access and egress to navigate. Max length 144in. Max width 36in. Slope 1:12. HANDRAILS.
Transfer Platforms
(Ans- Used to get from assistive devices to play equipment. Low slope, wide tread, handrails. Total height of platform = 11-18'
Steps = 14"D x 24"W(min) x 8"H(max)
Stepladders
(Ans- ages 5-12 ONLY for narrow tread. ages 2-5 must have wide tread
Slope, tread, open/closed risers, all depend on ?
(Ans- AGE
Handrails (childs hand should wrap?)
(Ans- at least 73% around
Platforms for (2-5) must have support if?
(Ans- foot and hand rail support if greater than 12" between them
Platforms for (5-12) must have support if?
(Ans- foot and hand rail support if greater than 18" between them
Arch Climbers (specifications)
(Ans- NOT sole means of access for 2-5 year olds. MUST attach at or below platform
Flexible Components (specs)
(Ans- NOT sole means of access, attached at both ends, wide enough for 2-5 years to bring both feet to each rung, and anchored BENEATH surfacing.
Guardrails and barriers are used to?
(Ans- prevent inadvertent falls
Fall prevention for 2-5 years (heights and needs)
(Ans-
under 20" (nothing)
20"-30" (guardrails required)
over 30" (barriers required)
Fall prevention for 5-12 years (heights and needs)
(Ans-
under 30" (nothing)
30"-48" (guardrails required)
over 48" (barriers required)
max opening for guardrails and barriers
(Ans- less than 15" (users need to exit single file)
Designated Playing Surface
(Ans- flat, larger than 2"x2", 30 degrees from level, elevated surface that can be used for sitting, walking, climbing, or standing.
Guardrails boundary for 2-5 years
(Ans- max opening at lower boundary 23"
guardrails boundary for 5-12 years
(Ans- max opening at lower boundary = 28"
Platform/Bridge/Walkway
(Ans- flat surface where multiple people can move freely, horizontal, +/-2 degrees, does hold water
Roofs 84" above playing surface
(Ans- can be any angle. roof supports should discourage climbing.
Roofs 84" below playing surface
(Ans- roof should not cover playing surface.
Impact Attenuating Surfacing (IAS)
(Ans- protective surfacing that absorbs impact to reduce risk of head injury
Critical height
(Ans- Highest fall height that is support by the type of surfacing, therefore it is a characteristic of the surfacing
Critical Height vs fall Height
(Ans- critical height should be greater than or equal to fall height of highest piece of equipment. fall height is a characteristic of the equipment
Deciding type of surfacing consider.....?
(Ans- critical height/fall height, cost, wear and tear(use), environmental concerns/weather, wheelchair accessibility (complying with F-1951)
Surface System
(Ans- all materials that contribute to impact absorption to minimize the likelihood of head injury
Loose-fill system
(Ans- small, independent, movable particles [Show Less]
