CalcType: Professional Playground Safety & Design Solutions — This comprehensive playground safety calculator suite is engineered to support evidence-based play space design, safety compliance assessment, and maintenance planning for landscape architects, play space designers, local authorities, and facilities managers. The Fall Height & CFH module calculates Free Height of Fall (FHF) and Critical Fall Height (CFH) for all common equipment types in accordance with EN 1176-1:2017 (playground equipment — general safety requirements) and ASTM F1487-21 (consumer safety specification for playground equipment). The Impact Surfacing module determines minimum depth requirements for impact-attenuating surfaces per EN 1177:2018 (impact attenuating playground surfacing) and ASTM F1292-22 (impact attenuation of surfacing materials), including HIC (Head Injury Criterion) and g-max thresholds. The Safety Zones module calculates equipment-specific use zones and combined safety zone footprints per EN 1176 Section 8 and ASTM F1487 Section 8. The Capacity & Layout module applies Fields in Trust (FIT) benchmark guidance for equipped play area provision. The Accessibility module assesses compliance with ADA Standards for Accessible Design §240, EN 16 630:2015 (inclusive play spaces), and AS 4685. The Inspection & Maintenance module structures inspection regimes per EN 1176-7:2008 (installation, inspection, maintenance, and operation) and CPSC Handbook for Public Playground Safety. Technical Disclaimer: All safety calculations, fall height assessments, surfacing depth requirements, zone dimensions, and maintenance schedules provided by this calculator are intended for preliminary design guidance and feasibility assessment only; they do not constitute a formal playground safety audit, risk assessment, or compliance certification. All playground designs must be verified, inspected, and certified by a qualified playground safety inspector holding current registration with RPII (Register of Play Inspectors International), ROSPA Play Safety, CPSI (Certified Playground Safety Inspector, NPSI), or equivalent national body prior to construction, installation, and public opening. CalcType assumes no liability for injury, death, regulatory non-compliance, or insurance claims arising from the use of these estimation tools.
