What is Head Injury Criterion and Critcal Fall Height?
Head Injury Criterion (HIC) is a measure of the likelihood of head injury arising from an impact. The HIC can be used to assess safety related to vehicles, personal protective gear and playground equipmenat and materials. The critical fall height is determined by the height at which the Head Injury Criterion value equals 1000, rounded down to the nearest 10cm. If children fall from below this critical fall height then life threatening serious injury is less likely. Hence, designers wishing to install protective safety surfacing around playground equipment should request the appropriate test data from the manufacturer, enabling them to design the installation so that the probable maximum fall height of children using the
equipment does not exceed this critical value.
Megasafe Safety Floor Systems is manufactured in compliance with ISO 9001 procedures and meets the EN 1177 European Standard which requires a specific HIC (Head Injury Criterion) value, depending on the type of playground or creche flooring (with regards to shock absorbing performance). This standard defines the parameters of compliance in order to classify shock absorbing materials in playgrounds. Therefore, it is of major importance to select the suitable flooring according to the different types of applications and significantly reduce accidents due to falls.

|Megasafe Edging Joints |
These ramp shaped modular elements are complementary to the tiles and are placed adjacent to the tiled surface. They eliminate any barrier existing between the flooring and ground surface thus removing a potential trip hazard.
|Megasafe Connecting Pins |
They are applied to tiles to improve their stability. These are necessary when the sub-base is not levelled or smooth.
Megasafe is self-levelling and self-fixing through the use of our joint pins. Panels can be laid directly on a sub-base of draining material, such as sand or fine gravel, provided it is well levelled and compacted. They can also be laid on a hard sub-base, such as concrete or asphalt, and spot-glued to the base with a special adhesive. It is recommended that the sub-base is sloped a minimum of 2%, so as to allow water to run off. To complete the installation, along the whole perimeter of the tiled area it is recommended to use the special edging joints and blunt corners so as to eliminate any transition step.
