crowd control barriers: A Complete Buying Guide for Events
Whether you're managing a music festival, outdoor market, sporting event or public demonstration, crowd control barriers are essential for public safety and event flow management. This guide covers everything event organisers, security managers and venue operators need to know.
Types of Crowd Control Barrier
Steel Interlocking Crowd Barriers (Mojo/Festival Style)
The most common type for outdoor events. Galvanised steel panels with feet that prevent toppling, and interlocking ends for easy linear runs. Typically 1.1m high and 2.2m wide per panel. Stackable for transport.
water-filled barriers
Plastic barriers filled with water for ballast. Lighter to transport, can be linked in series. Popular for road closures, street events and temporary pedestrian channels. Not recommended for high-density crowd situations.
Concrete (Jersey) Barriers
Solid concrete sections for vehicle exclusion at events where HVM is required. Heavy and permanent-feeling — often used at high-profile events following terror threat guidance.
Retractable Belt Barriers
Post-and-belt systems for queuing management and indoor crowd guidance. Low barrier — suitable for orderly queuing but not crowd containment.
Event Safety Standards in the UK
UK event safety is governed by the Purple Guide (published by the Events Industry Forum), HSE guidance and local authority licensing conditions. Key crowd barrier requirements:
- Barrier load ratings must suit the expected crowd density and behaviour
- Front-of-stage pit barriers must be positioned to allow crowd evacuation
- Emergency egress must not be blocked by barrier configurations
- Barrier systems must be inspected before and during events
Calculating How Many Barriers You Need
Basic formula for perimeter fencing:
- Measure total perimeter in metres
- Divide by panel width (typically 2.2m) to get panel count
- Add 10% contingency for gates, corners and overlaps
For a 200m perimeter: 200 ÷ 2.2 = 91 panels + 10% = ~100 panels
Crowd Density Guidelines
| Density | Persons/m² | Risk Level |
|---|---|---|
| Comfortable | Below 1 | Low |
| Standing crowd | 1–2 | Managed |
| Dense crowd | 2–4 | High — monitor |
| Crush risk | Above 4 | Emergency action |
Buying vs. Hiring Crowd Control Barriers
Hire: Suitable for one-off events. Includes delivery, collection and often erection. No storage needed. Higher per-event cost.
Buy: Cost-effective for regular event organisers, venues, councils. Breaks even at approximately 4–6 hire events. Requires storage and transport.
FAQ
How much do crowd control barriers cost to buy?
Steel interlocking crowd control barriers typically cost £40–£80 per panel when buying new. Bulk orders of 50+ panels attract significant discounts.
What weight can crowd control barriers hold?
Standard steel interlocking barriers are rated for horizontal loads of 2–3 kN/m. For high-pressure front-of-stage applications, specialist heavy-duty barriers rated to 5 kN/m+ are required.
Can crowd control barriers stop vehicles?
Standard crowd control barriers are NOT rated for vehicle impact and should not be used for HVM purposes. For events requiring vehicle exclusion, use PAS 68-rated concrete barriers or vehicle-tested steel barriers.
