The security staff should wear the following personal protective equipment (PPE):
High visibility jacket
Wearing a high visibility jacket ensures that the helicopter pilot is able to identify ground personnel and determine who is part of the receiving team and who is a casual bystander.
Eye protection
Glasses protect against eye damage from loose debris that might be thrown up by rotor downwash.
If debris is dislodged by downwash and you are temporarily unable to see, stop moving towards the helicopter, crouch down and take time to allow debris to settle and vision to clear.
Ear protection
Long-term exposure to aircraft engine noise may cause hearing damage; wearing hearing protection will minimise this.
