Fire Safety on Construction Sites

Construction sites carry high fire risk — hot works, flammable materials, temporary electrics, and changing layouts all add up. A clear fire plan and regular checks keep it under control.

The fire triangle on site

Fire needs heat, fuel, and oxygen. Construction adds all three: ignition from hot works and electrics, fuel from timber, packaging, and fuels, and unrestricted airflow. Remove or separate any one and you prevent the fire.

Key controls

• Hot works permits — control welding, grinding, and cutting, with a fire watch after
• Good housekeeping — clear waste and combustibles daily
• Safe storage — flammables and gas cylinders stored correctly and secured
• Means of escape — clear, signed routes kept unobstructed
• Detection and alarm — appropriate to the site phase
• Extinguishers — right type, in date, and accessible

Plan for escape

Everyone on site should know the alarm, the escape routes, and the assembly point. Review the fire plan as the build changes — routes that worked at first fix may be blocked by second fix.

Check it regularly

Fire risk on a site is never static. Routine checks of extinguishers, escape routes, and storage catch problems before they matter. SiteAudit lets you run fire-safety checks on a schedule and keep dated evidence that controls were in place.
