A guardrail post holder for coupling a guardrail assembly to a formwork system, the guardrail post holder comprising:

• a spine having a top end portion, and a bottom end portion;
• a socket coupled to the top end portion of the spine and configured for receiving a guardrail post of the guardrail assembly;
• a plate coupled to the bottom end portion of the spine and configured to selectively secure the guardrail post holder to a formwork support component of the formwork system,
• wherein the plate includes a pair of plates coupled to the bottom end portion of the spine and laterally spaced from one another to define a gap therebetween, the gap being configured to receive an end of the formwork support component to prevent the guardrail post holder from rotating about a longitudinal axis of the formwork support component, wherein the pair of plates are parallel to one another;
• a safety pin, wherein the pair of plates each define a hole therethrough configured for receipt of the safety pin, wherein the safety pin is configured to be received through the holes in a direction perpendicular to the pair of plates;
• and
• a toe-board stop plate protruding outwardly from the socket to maintain a gap between the formwork support component of the formwork system and the top end portion of the spine.
