These units are designed to safely contain suspect mail and parcels. They come in two main variants: top‑opening and front‑opening. You can also add optional features such as security locks, earthing points, inner shelves, fixed legs instead of wheels, and vehicle‑mounting brackets.
These options make the units suitable not only for handling suspect items but also for storing explosive samples in laboratories and vehicles. The Mailsafe range now includes the larger Mailsafe 200, which is built for managing parcels in high‑volume handling facilities.
Moving and storing detonators often creates logistical challenges and unnecessary costs. Detsafes offer a practical way to overcome these issues. Our SJH Projects detonator containers are engineered to lower the Hazard Classification to the same level as small‑arms ammunition (1.4S). This reduction provides far greater flexibility and improves safety for anyone who works with or near these items.
The Detsafe range continues to expand, if you don’t see what you need then let us know – it could be the next one we develop,
K9‑Safe units provide physical security, fire protection, and blast containment for the explosive samples used when training and deploying sniffer dogs. Each unit is designed to bolt securely to the floor of a K9 vehicle.
The K9‑Safe combines the key features of both the Mailsafe and Detsafe systems, bringing their proven strengths into one solution.
Originally developed for a European Police Force, the K9‑Safe helped them maintain their explosive search dog operating licence. It is now available worldwide.
The Det‑Pad system allows key parts of the explosive train to be connected while reducing the flash and fragmentation they can produce. It was developed in response to requests from the user community, making the system both flexible and adaptable.
Det‑Pads can also be used to remove a detonator from a charge while it is still connected. Once removed, the Det‑Pad shields the detonator to prevent it from initiating the charge or affecting nearby detonators
If a device detonates while it is being X‑rayed, the scanner’s body can add significant fragmentation. This increases the risk of damage to both people and property. To reduce this danger, SJH Projects can design a Scansafe casing for your scanner, using the same proven protection technology found in the Mailsafe range.
The Det Cone is used to safely test detonator circuit continuity. This customer‑driven development is designed for specialist situations where, once deployed, the detonator becomes dangerous and costly to retrieve if it is found to have no circuit continuity.
Typical examples include oil and water well heads, where detonators are used as part of the process to clear debris from the boring system.
A discussion at the DSEI defence show in London posed the question on the possibility of adapting our Detsafe technology to safely contain an array
We have recently completed the design phase for a novel blast/pressure containment vessel. This will allow the customer to perform research and proofing of their
