OBJECTIVE
Prevent personnel from entering hazardous areas during lifting, excavation, pressure testing, hot work, falling-object exposure and mobile-equipment operations.
WHY IT MATTERS
Poorly positioned barricades can create a false sense of security.
The exclusion zone must consider swing radius, falling objects, pressure release and equipment movement, not only the immediate work point.
Barricading is ineffective when workers do not understand the hazard, access restriction or responsible person.
REALISTIC SITE SCENARIO
During a crane lift, barricades were placed only around the load landing area.
The suspended load swung outside that boundary while a worker believed he was standing in a safe area.
A wider exclusion zone based on crane radius and possible load movement would have prevented the exposure.
REMEMBER
Place the barricade beyond the maximum reach of the hazard, not simply around the work point.
KEY HAZARDS
Uncontrolled entry into equipment or suspended-load movement areas.
Falling or projected objects travelling beyond an inadequate barricade.
Unauthorised approach to excavations, openings or level changes.
Whipping hoses or failed fittings during pressure testing.
Interaction between pedestrian and vehicle routes.
Poor barricade visibility during night or low-light work.
Damaged or missing barricades allowing uncontrolled access.
Missing or unclear warning information at restricted areas.
CONTROLS
Identify the maximum hazard reach and place barricades beyond that boundary.
Use the correct barricade type and colour coding required by site rules.
Clearly display the hazard and access restriction.
Establish controlled entry points and attendants where required.
Confirm pedestrian routes do not pass through the restricted area.
Use reflective barricades or additional lighting for night work.
Define pressure-test and lifting exclusion distances through risk assessment.
Inspect barricade integrity throughout the shift.
Remove barricades only after the area has been confirmed safe.
Reassess the exclusion zone whenever the task or site conditions change.
SUPERVISOR MESSAGE
Team, simply standing outside a tape line does not guarantee safety. Today we will position barricades according to the real hazard radius, control access and maintain the exclusion zone throughout the job.
TEAM QUESTIONS
What hazard requires an exclusion zone today?
How was the barricade distance determined?
How will unauthorised entry be prevented?
Is the barricade visible at night?
Who controls entry where access is required?
Who will reassess the area if conditions change?
FIELD VERIFICATION
Hazard area identified
Barricade distance suitable
Entry points controlled
Warnings displayed
Barricade intact
