Hazard Identification Part 3

Question 1

What are the standards for field tools to test for Crush and Shear Hazards?

Answer 1

Neoprene rods with a specific hardness rating. Note - There are 2 completely different tests for crush and shear, one for roller slides and merry-go-rounds and a different test for all other common crush and shear hazards

Question 2

What are the measurements for the crush and shear hazards?

Answer 2

For roller slides - 0.19” (3/16”) diameter dowel
For merry-go-rounds - 0.30” (5/16”) diameter dowel
Common Crush/Shear - 0.62” (5/8”) diameter dowel

Question 3

On Access/Egress Stairways, they have easy access for the very young

Answer 3

Low slope of ascent and descent
Wide treads and low risers
Handrails needed

Question 4

On Access/Egress Ramps, they are the most effective means of providing wheelchair access to elevated platforms

Answer 4

Maximum ramp slope 1:12
Maximum ramp run without a landing is 144”
Elevated accessible routes must have minimum width of 36”
Landings must have a 60” minimum diameter

Question 5

Handrails are provided for balance and support, what is their height requirement?

Answer 5

Handrail height is between 22”-38” from leading edge of each step. Hand support needed at the first step

Question 6

What information is relevant to handrails and handgrips?

Answer 6

Children’s fingers should wrap around at least 75% of the handrail perimeter
Rigid components - 0.95-1.55
Flexible components - 0.62-1.55

Question 7

Arch Climbers used for access

Answer 7

Should not be the sole means of access to elevated platforms for pre-school equipment
Arch climbers, flexible climbers and rung ladders used for final access should not connect to the structure above the platform

Question 18

3 Dimensional Climbing Net Structure

Answer 18

The mesh structure shall be arranged so there is no clear opening between flexible members with a vertical dimension greater than 72” and a diameter of 18” for ages 2-5, 20” for ages 5-12. Flexible components used for hand gripping shall be between 0.62”-1.55”
