Control measure knowledge
Where a boil-over is suspected or predicted, the incident commander should be vigilant for signs of a boil-over and ensure crews are at a suitable distance away if a boil-over is imminent. A boil-over is usually preceded by a period of quieter burning followed by a marked heightening and brightening of the flames.

Strategic actions
Provide procedures and support arrangements regarding the hazards that may be encountered and actions to take when implementing hazard area for boil-overs
Tactical actions
Establish exclusion zones, inner and outer cordons based on level of risk from a boil-over or slop-over
Assess the surrounding risks and potential impact of a boil-over
Implement suitable cordon controls from any potential boil-over
