An NRBC business continuity plan defines the plausible scenarios, the referents, PPE stocks, containment or shutdown procedures, messages to teams, waste management, cleaning and recovery criteria.
The CBRN PCA begins with decision thresholds
A company does not need a spectacular document. It needs prepared decisions: when to shelter, when to evacuate on order, when to suspend an activity, who talks to employees, where PPE is located and how to avoid cross-contamination.
The scenarios must remain plausible: chemical leak nearby, transport of dangerous materials, suspicion of biological contamination in a premises, high viral circulation, nuclear alert or temporary unavailability of a building.
Each scenario must link a risk, an instruction, a person in charge, equipment, a method of information and a written record minimal.
Bricks to formalize
Organization: referent, substitute, emergency contacts, official channels, list of vulnerable people, internal communication plan, visitor and service provider information.
Equipment: PPE stock by size, masks, gloves, glasses, gel, wipes, waste bags, clean zone/dirty zone marking, radio, lamps, batteries and verification procedure.
Resumption: reopening conditions, cleaning, ventilation, removal of consumables, monitoring of exposed people, replacement of PPE and feedback.
Bring the plan to life beyond the document
A continuity plan is only useful if the teams know who decides and where to find the information. Roles must be assigned to identified individuals, with at least one alternate. Contact details, access, critical suppliers and ready-to-use messages benefit from being brought together in a short version, accessible even when the usual tools no longer work.
A simple exercise quickly reveals the gaps: inaccessible stock, mask of the wrong size, outdated directory, uninformed employee or procedure that is too long. There is no need to stage a spectacular crisis. Testing a cascade call, sheltering or working in degraded mode is often enough to significantly improve the organization.
After an incident or exercise, resumption must be documented with the same care as shutdown. Who authorizes the return, which areas remain prohibited, which equipment is replaced and how are the teams informed? These questions avoid a hasty recovery and give the manager a clear record of decisions.

What priority depending on the situation?
| Situation | Priority | Vigilance point |
|---|---|---|
| Immediate danger | Move away, alert, follow emergency services | Do not try to identify or treat alone. |
| Short break | Light, information, telephone, water | Preserve the battery and avoid flames. |
| Extended event | Rotation of reserves and family plan | Reassess with the information local. |

Recommended situations and routes
Chemical risk nearby
Take shelter, close ventilation if requested, inform teams and stop exposed activities.

Listening to authorities, confinement or evacuation on order, no taking iodine without instructions.

Is an NRBC PCA reserved for industrial sites?
No. ERPs, communities, businesses, schools, warehouses and associations can formalize simple reflexes adapted to their exposure.
What PPE stock should you need?
The stock depends on the workforce, sizes, scenarios, durations and replenishment time. It must be checked regularly.
Who should decide in the event of an alert?
A referent and a substitute must be identified, with a clear rule: follow the authorities and do not improvise any intervention.
How often to test a PCA?
At least once a year and after any significant change in premises, team, activity or risk. A short and regular test is better than a rare and overly complex exercise.
