Recognizing Letter Bombs Training at Cocoon
Recognizing Letter Bombs is a targeted training for anyone who receives, sorts, or processes mail and packages. Participants learn to identify the physical and behavioral characteristics of suspicious mail items, such as unusual weight, shape, packaging, sender details, and suspicious codes, and receive a clear step-by-step plan for when they have doubts.
The training explicitly focuses on procedures: who to call, when to involve law enforcement (parketpolitie), and how to safely secure a suspicious mail item without endangering one’s own safety or that of colleagues. The content aligns with Cocoon’s broader mail screening and hazard management programs, ensuring that mailroom and screening procedures are integrated rather than operating independently.
The result is confidence in recognizing suspicious characteristics in a timely manner rather than only in retrospect, a concrete action protocol for moments of doubt, and clarity on whom to alert and how to safely isolate a suspicious mail item.

Who is this training for?
The training is intended for mailroom staff, reception staff, and security personnel who daily process incoming mail and packages.
Recognizing Letter Bombs is often implemented in organizations with an elevated risk profile or high volumes of external correspondence, after a specific incident or threat elsewhere in the sector, or as a supplement to an existing mail screening program to ensure seamless integration of mailroom and screening procedures.
Why choose Cocoon
Cocoon offers Recognizing Letter Bombs not as a standalone course, but as part of a cohesive whole with its mail screening and hazard management programs. This means that mailroom and screening staff work according to the same procedures, with the same reporting structure and the same criteria for when law enforcement (parketpolitie) is involved.
Doubt is not a weakness. Doubt is precisely the moment when the procedure must take over.
Recognizing Letter Bombs combines well with Advanced X-Ray Training, ensuring that mailroom and screening procedures within the same organization remain aligned.
- Direct integration with broader mail screening and hazard management programs
- Concrete step-by-step plan for moments of doubt, not abstract theory
- Clear agreements on whom to alert and when law enforcement (parketpolitie) is involved
Practical example: how mailroom and screening procedures align
Within the broader mail screening program, procedures regarding the involvement of law enforcement (parketpolitie) and the handling of suspicious mail items and codes are explicitly detailed, so employees do not have to improvise when a suspicious mail item actually presents itself.
Frequently asked questions
What is the cost of the Recognizing Letter Bombs training?
The costs depend on the group size and duration, and whether the training is combined with Advanced X-Ray Training. You will receive a customized quote following a brief intake.
What Should I Do If I Encounter a Suspicious Mail Item?
That is precisely what the training covers: a concrete step-by-step plan for moments of uncertainty, including who to call, when to involve law enforcement, and how to safely isolate the mail item without endangering yourself or colleagues.
Is a certificate provided upon completion of the training?
Cocoon primarily focuses the training on practical application within your own organization, rather than on external certification.
What is the difference between Recognizing Letter Bombs and Advanced X-Ray Training?
Recognizing Letter Bombs focuses on the physical and behavioral characteristics of suspicious mail, often without scanning equipment. Advanced X-Ray Training specifically focuses on identifying suspicious objects on X-ray images within the scanning line. Both programs complement each other in terms of content.
Who Should Attend?
For mailroom staff, reception staff, and security personnel who handle incoming mail and packages daily.
Can this training be combined with our existing scanning lane program?
Yes, and it is recommended. This aligns mailroom and scanning lane procedures, ensuring all involved employees adhere to the same reporting structure.
