Hazard Identification Part 2

Question 1

What injury is associated with Completely Bounded Rigid openings?

Answer 1

Possible strangulation due to head entrapment after feet-first entry into opening

Question 2

What are the users at risk?

Answer 2

Pre-School Age 2-5

Question 3

Are all Completely Bounded openings hazards?

Answer 3

No, openings between 3.5” and 9”. Note - the higher the location of the accessible opening, the greater the possibility of serious injury. Especially check equipment before 1991

Question 4

When checking for head entrapment in a Completely Bounded Rigid opening with a probe, which probe do you use first?

Answer 4

Torso probe (based on dimensions for the 5th percentile of 2 year olds

Question 5

When checking for head entrapment in a Completely Bounded Rigid opening, if the Torso probe goes through the opening, which probe do you use second?

Answer 5

Insert the Head probe (based on the dimensions of the 95th percentile of 5 year olds

Question 6

What is a Partially Bounded opening and which user are at risk?

Answer 6

Any opening in a piece of play equipment that is not totally enclosed by boundaries on all sides so that the perimeter of the opening is discontinuous. Pre-School Age 2-5

Question 7

What is an exception of a Partially Bounded opening entrapment?

Answer 7

Where contact with sides of the opening is less than 24” above the protective surfacing. Note - Not all Partially Bounded openings are hazardous

Question 8

What is a projection?

Answer 8

It is a part of the playground equipment that extends or juts out beyond the adjacent surface. Many projections are safe

Question 9

What are the projections that have a potential to injure users identified by ASTM?

Answer 9

Protusions

Question 10

How many projection gauges are used to identify protusion hazards?

Answer 10

4
Smallest gauge identifies projections that could penetrate a child’s skull at the temple region
Middle gauge identifies projections that could penetrate a child’s brain through their eye socket
Largest gauge identifies projections that could bruise or rupture an internal organ
The washer-like flat gauge is used to check for protusions on suspended components such as swings

Question 11

What is an Entanglement Hazard?

Answer 11

A projection that has the potential means to catch a loose cord, hood or any item around a child’s neck

Question 12

A projection is not an Entanglement Hazard unless 4 conditions are present, what are they?

Answer 12

Projection must fit within a projection gauge
Projection must be above the horizontal plane
Projection must have perpendicular sides
Projection must extend > 0.12” (1/8”) from initial surface
