Guidelines for Barricading on Construction Site | Tips for Barricading | Procedure of Barricading | Types of Barricading

Before starting any civil engineering work it is important to know the suggested guidelines for barricading at the construction site, also know about the procedures of barricading and different types of barricading which not only helps in making the construction site safe but also help to reduce any type of hazard at the construction site.

What is Barricading?

Barricades are used as warning devices, alerting people to dangers on construction sites. They are also used to control the movement/divert of traffic on the roads and to protect critical installations like gas holders, electrical substations etc.

The Consultants, Site Incharges of the Central Project Engineering Division, Safety Engineer and Operations Departments are responsible for ensuring that the worksite is correctly barricaded.

Guidelines for Barricading on Construction Site

  1. Substantial barricades shall be provided for the areas where excavation, trenching, construction and demolition work are being performed for the protection of workers, public safety, or as required by-laws.​

  2. Barricades shall be provided to protect people from construction associated hazards and to prevent trespassing into vital installations as per the requirement of prevailing laws.

  3. An opening of 30 cm or more in any floor, platform, sidewalk or yard through which a person may fall; Such as hatchway, ladder or ladder opening, pit, large manhole, barricading should be there.

  4. Traffic flow will be controlled by directing vehicles into the designated lanes using appropriate barricades.

  5. To alert people well in advance, all barricades must be visible from a safe distance. 

  6. There will be a diversion board, a closure board, and a warning board at each end of the barricade.

  7. At both ends of the barricades, two people will be deputed with flags and whistles.

  8. If the work is to be done after sunset, red lights should be provided on the barricades.

  9. No material will be projected or spilt beyond the barricades.

  10. Once the job is complete, only official personnel may remove the barricades.

  11. To protect the sharp projection of open bars at the construction site as well as in plants, other projected bars, valve spindles etc must be covered with Bar-caps.

Roles and Responsibility for Barricading on Construction Site

Project Manager/Head Of Department

  1. Deployment of codes of practices at sites/on the shop floor 

  2. Advice review and allocation of recourse to close gaps 

  3. Implement effective practices to bridge the gaps in the deployment of the Code of Practices within the department.

Site In-charge/ Team Leader:

  1. Execute the barricading plan 

  2. Visit sites and implement best practices on the shop floor or at sites with supervisors.

Various types of Barricades

Barricades can be classified into two groups, 

  1. Indicative Barricades and

  2. Protective Barricades.

A group of Indicative barricades include Safety tape, portable steel frame barricades, portable road barriers like cones, drums and road runners.

A group of protective barricades including rail guards, concrete guards, steel frame barricades grouted firmly onto the ground, permanent fencing etc.

The type of barricade will depend on the requirements and statutory provisions.

Danger Flag on Construction site

  1. Barricades shall be erected with a sufficient number of Danger Flags attached to each side to provide a visible warning. A Danger Flag has to be attached to each recognized entry point.

  2. If a barricade has more than one recognized entry point, each entry point flag should be marked with a Danger Flag.

  3. During the duration of its use, the barricade and the attached Danger Flags must be maintained in good condition.

  4. Alternative safe access (walkway) will be provided if a barricade crosses a recognized walkway. A Danger Flag and Warning Tag shall be displayed across the walkway in such circumstances.

Primary functions barricade with Danger Flags

  1. To restrict access to a construction site containing hazards and risks.

  2. In order to protect personnel working in a defined area from unauthorized access by any other person or activity.

  3. The flags should be supported by ropes of sufficient diameter strung between supports at a minimum height of 1m above the working floor level, clearly visible from the approach. The flags should be attached at a maximum distance of 5m.

  4. Danger Flags should be printed in hardbound paper with a plastic cover, with the size of the flag being A4 (297 x 210 mm), and the ID of the eyelet to be 4 mm.

Guidelines for Barricading on Construction Site

It is mandatory to barricade all construction sites using the appropriate barricades as outlined below:

  1. Barricades must surround construction sites around their perimeter (standard drawing given below)

  2. Where construction debris is deposited without the use of an enclosed chute, the area must be barred with either an angle or square hollow section, or pipes, with 1-metre clearance from the materials deposited.

  3. If a maximum of one day is required to complete the work, areas with temporary wiring over 600 volts shall be barricaded with a sign barricade containing "red-white" security tape. If the work takes more time, the site should be closed with protective barricades as per the above diagrams. Plastic barriers should not be used for barricading in the work area.

  4. The swing radius of the rotating superstructure of the crane or other equipment is to be protected by using 'Red White' safety tape of a minimum of 50 mm wide. One edge of the tape should run continuously from post to post at 1000 mm above the ground. Another edge of the tape is to run 300mm above the ground.

  5. An excavation site that is 1 metre or deeper must have a protective barricade at least 1200mm high based on the standard drawing provided.

  6. For gas-cutting and welding sites without excavation, 'Red-White' safety tapes should be used to warn workers.

Guidelines for Barricading on Destruction site

  1. A Danger Flag with a Warning Tag must be placed across a barricade that crosses a recognized walkway. Alternative safe access walkways will be provided in these cases.

  2. Properly cover or securely barricade all floor or ceiling openings/elevator shaft entrances/doors leading to stairs.

  3. If floors are being removed, the area underneath must be properly barricaded so that no other workmen are able to enter. 

  4. Each floor opening/wall opening shall be adequately guarded/barricaded.

  5. On and around the barricades should be red and/or luminescent danger signs at night.

Guidelines for Barricading on Road site

  1. Before carrying out work on the road or on the side of the road, the executive agency shall obtain approval for road work from the Department of Safety. Barricades to control or protect the traffic are to be provided as per the criteria given below and approved by the site in charge and the security officer of the department concerned before commencing the work.

  2. The executing agency shall make the safe working procedures for the work with the help of the security officer of the concerned department.

  3. Care should be taken to block only half of the width of the road at a time. Caution boards and boards indicating diversion are to be installed on both sides of the barricades.

  4. If the entire width of the road is to be blocked, road turning/diversion signs will have to be prominently placed in addition to warning boards at both ends of the work area.

  5. If access by construction vehicles is required, the contractor or agency performing the work is responsible for properly replacing the barricades immediately after the construction vehicle entry and exit.

  6. If access to the local office building is to be maintained beyond the point of closure then a sufficient opening should be provided between the barricades to allow safe entry and exit through the closure.

  7. A white coloured drum with red stripes in the middle and a barricade with red/white security tape can be used as a barricade.

  8. Traffic control will be handled by two people with red/green flags and whistles deployed on both sides of the barricade.

  9. If equipment is left unattended near a roadway at night, barricades should be put up around it.

  10. Whenever road works are performed near a railway track or level crossing, safety precautions must be strictly followed, including barricading the worksite.

Guidelines for Barricading of Water Sources

  1. Rail guards, handrails, and mid-rails must be installed permanently on both sides of roads that pass over dams.

  2. Any bridge crossing a stream or river must have handrails, mid-rails, and toe guards.

  3. Permanent rail guards are to be buried in the ground along the roads passing along water bodies like lakes, cooling ponds etc. Equal guards are to be installed on both sides of the roads leading to the top of the dam.

Guidelines for Barricading for positive isolation

  1. For positive isolation, entry into the Construction site area of personnel and trucks and cranes will be restricted using barricades.

  2. There should be separate gates for personnel and trucks.

  3. Individuals may enter the barricades through self-closing doors.
