|
ASTM F1951 covers _____.
|
Wheelchair Accessibility of surface systems under and around PG equipment.
Equipment selection and location, along with the type of protective surfacing are key components to ensuring the opportunity for children with disabilities to play on the playground. |
|
Age Separation:
|
the layout of pathways and landscaping of the PG should show the distinct areas for the different age groups.
Areas should be separated at least by a buffer zone (area with shrubs or benches) This will reduce the chance of injury from older, more active children running through areas filled with younger children with generally slower movement and reaction times. |
|
Age Group:
|
In areas where access to PG is unlimited or enforced only by signage, the PG designer should recognize that since child development is fluid, parents and caregivers may select a PG that is slightly above or below their child's abilities - especially for children at or near a cut-off age (2 or 5).
Many reasons for this (supervising multiple kids, misperceptions about hazards to children of a different age, advanced development of a child, etc) That's why there is an overlap for age 5 THOSE WHO INSPECT THE PG SHOULD USE THE INTENDED AGE GROUP OF THE PLAYGROUND. |
|
Risk Management Plan |
Comprehensive program designed to reduce life-threatening or debilitating injuries Shows good intent Provides legal evidence |
|
5 Elements of Risk Management Plan |
1 - Safety Policy 2 - Leadership (safety Coordinator) 3 - Site History File 4 - Safety Audit 5 - Inspections, Repairs, Maintenance |
|
Risk Management Plan - First Step |
Formalize Safety Committment Establish a Safety Policy approved by governing board - Emphasize agency commitment to PG safety - Establish standard of care - Compel provision of safety-related resources - Provide authority to make PG-related safety decisions - Minimize exposure to risk |
|
Risk Management Plan - Leadership |
Identify and Appoint a PG Safety Coordinator - They involve everyone - Facilitate agency's commitment to PG safety - Identify, assess and assign tasks and responsibilities - Identify acceptable levels of risk exposure - Maintain continually-changing PG environments - Ensure maintenance and inspections are completed appropriately - Do NOT review and approve inspection forms |
|
Risk Management Plan - Site History File |
Must be kept for each playground site Contains: - Contact info - Insurance certificate - Maintenance/repair instructions - Inspection procedures - Parts lists - Installation Instructions - Specs/bids/docs - PO's/contracts/award docs - Site plans/drawings - PG audit reports - Inspection frequency checklist - Hi/Low frequency inspection reports - Copies of complaints - Copies of WO's - Accident/incident reports - Accident investigation reports - Accident summary reports / studies |
|
Risk Management Plan - Safety Audit |
Purpose of audit is to: Examine play equipment, surfacing and signage using agency policies and procedures and current standards and guidelines in order to: - Identify non-compliant conditions - Identify compliant conditions |
|
Perform a safety audit when: |
- Before the PG opens - Beginning of risk management plan - New equipment is installed - After major repair - When standards/guidelines update/change - Laws require audit - Case law established. **Recommended that an audit is Only performed by a CPSI (not lawyer) - but must |
|
Safety Audit/Inspection - difference |
AUDIT - ESTABLISH standard of care - Based on national standard. INSPECTION - MAINTAIN standard of care and Identify new hazards - Proactiv - shared responsibility |
|
Frequency of inspections is determined by: |
Equipment/Surfacing factors - Age, type, design Environmental factors - soil, drainage, climate, shade, when is PG used (year round?), open now? supervised/unsupervised |
|
Low-frequency inspections |
- Seasonal, in-depth - Inspect each component - Focus: Preventive maintenance - PROACTIVE - take care of small issues when possible to prevent big issues. Replace common hardware on site - work orders (keep records) - Produce work orders for for problems that can't be solved immediately - Cite ASTM/CPSC section on audit form when recommendation is made - Record all findings on site (photos, site plan) - Advise owner of high-priority hazards - Develop plan for taking equipment out of service if applicable - Only copies of PW on site (not originals) - The audit is confidential - only owner/operator or a specified agent may get the report |
|
High-frequency inspections |
Custodial - identifies change - FOCUS: Routine maintenance/scheduled maintenance - may be as much as several times a day - sudden/repeated issues such as storm damage, flooding, loose-fill surfacing depth in high-traffic areas - Rake surface, clean PG, pick up garbage - Document and submit WO for repair - Supervisor needs to review inspection form |
|
If equipment needs to be taken out of service: |
-Create a safe environment (caution tape, snow fencing, construction fencing, signs) *Construction fencing and signs are BEST way to take equipment out of service - try to minimize down time -Document - photos -When equipment is out of service, it draws attention - Have contingency plan before accident happens - Removal of equipment is NOT an admission of guilt - Form used is specific for agency - ONLY a CPSI should investigate. An attorney may NOT participate |
|
Hazard Priority Rating Scale |
Rating of 1-5 in order of severity CONSTANT #1 - FIX NOW - potential for loss of body part, permanent disability or death EX: exposed footers, gap at top of slide transition area, heavy metal animal swings #2 - FIX ASAP - potential for serious injury - temporary disability EX: Broken swing chain, missing or loose hardware on upper body equipment #3 - FIX WHEN TIME PERMITS - potential for minor or non-disabling injury EX: Surfacing under swings or slide exit, Bolt with 3-4 threads exposed below decks and platforms #4 - CORRECT WHEN WORSENS - very minimal injury EX: worn swing seats, loose hardware on ground level panels #5 - COMPLIANT EX: Inadequate shade (don't understand this one), litter |
|
Safety Audit |
ESTABLISH standard of care Based on national standard. Audit Process: Identify compliant and non-compliant conditions using probes, gauges and current standards and guidelines. Determine a Hazard Priority Rating for non-compliant conditions based on predictable results (possibility, probability, consequences). Provide a basis for all findings. Establish repair/removal/replacement priorities based on injury potential. Correct non-compliant conditions When non-compliant conditions have been corrected, the Standard of Care has been achieved. |
|
Safety Inspection |
MAINTAIN standard of care Identify new hazards Proactive shared responsibility Carried out in a systematic manner by personnel familiar with the PG *Inspections alone do NOT constitute a comprehensive maintenance program |
|

CPSI Course Objectives |
1 - Identify safety hazards on PG's 2 - Rank the hazard according to injury potential 3 - Apply knowledge to establish a comprehensive PG safety program |
|
A comprehensive program of PG safety includes what three things? |
1 - Audits 2 - Inspections 3 - Maintenance |
|
Difference between a RISK and a HAZARD: |
RISK - how a child learns HAZARD - Known danger. Causes injury. |
|
Basis for Hazard Identification - Standards and Guidelines are developed from: |
National Injury Data (NEISS) Industry Experience Risk Management and Litigation Anthropometrics (measurement of the human body) WHY? Gain insight as to HOW and WHY injuries occur |
|
Function of a play environment is to help develop a child ________. (4 ways) |
Physically Intellectually Socially Cognitively |
|
PG injury overview - notes |
61 million children is US through age 14 Over 220,000 PG equipment related injuries annually 76% on public playgrounds 79% of those are from FALLS 11% of those are from IMPACT 83% of children injured are between ages 2-9 |
|
Guardrail should be placed ______________ to prevent a fall. |
Above the child's center of gravity |
|
Major cause of death and seriously debilitating injury on public playgrounds (Top 4) |
1 - ENTANGLEMENT (clothing, strings, ropes) 2 - FALLS (onto hard underlying surfaces) 3 - HEAD AND NECK ENTRAPMENT (in equipment openings) 4 - IMPACT (by tipped or loose equipment, or moving swings) ***Most deaths on RESIDENTIAL equipment is from entanglement and non-sufficient surfacing. |
|
Factors that contribute to public playground injuries |
Improper use / Poor supervision (we can not control) The following CAN be controlled: Poor Maintenance Inappropriate Design Installation Errors Site Planning Issues |
|
Most common cause of playground fatalities |
Entanglement |
|
The Hazard Priority Level is NOT based upon the potential cause of injury. |
The possibility of a head entrapment, entanglement or a fall does NOT automatically make any such hazard a Prioroty 1. Consideration must be given to the possibility, probability and consequences |
|
Hazard Priority Level is based upon three factors: |
1 - Possibility - the likelihood users would come in contact with the hazard Easy to access? In heavily-used area? Can condition become worse easily or quickly? 2 - Probability - what is the probability that a child would have an accident as a result of exposure? 3 - Consequence - The most likely level of injury to be the consequence of the accident. Will it result in major or minor injury? |
