Control measure

Identify and control the hazard area around a slurry pit or lagoon

Control measure knowledge

An appropriate hazard area around a slurry pit or lagoon should be identified and controlled, especially if there is a risk that the contents will be released.

Access into the hazard area should be prevented, or limited to essential tasks with only the minimum number of personnel. Personnel should not enter a slurry pit or lagoon unless there is an threat  to life.

Fire and rescue service personnel entering the hazard area should wear the appropriate level of personal protective equipment (PPE) and respiratory protective equipment (RPE).

Advice or assistance should be sought from a hazardous materials adviser if required. Specialist rescue teams and equipment may also be required.

As the atmosphere around slurry pits or lagoons may be toxic or irrespirable, it may be necessary to identify gases in the vicinity using regular atmospheric monitoring and to wear respiratory protective equipment (RPE).

Depending upon the materials involved it may be necessary to implement appropriate procedures for hazardous materials. For more information refer to the Foundation for hazardous materials and the National Operational Guidance: Hazardous materials.

Strategic actions

Fire and rescue services should:
  • Ensure that information about slurry pits or lagoons is included in Site-Specific Risk Information (SSRI)

Tactical actions

Incident commanders should:
  • Consider requesting advice or assistance from the responsible person before approaching the slurry pit or lagoon
  • Consider requesting advice or assistance from a hazardous materials adviser when working near slurry pits or lagoons

  • Ensure that  personnel are wearing appropriate PPE and RPE

  • Consider requesting the attendance of specialist rescue teams and equipment
  • Prohibit eating, drinking, smoking or vaping to prevent ingesting contaminants

  • Consider restricting the number of fire and rescue personnel and vehicles within the hazard area
  • Carry out testing and monitoring of the atmosphere around the slurry pit or lagoon
