Definitions

Authority Having Jurisdiction - Normally the local city, municipality or county building inspector. For Canadian Forces Bases the Authority Having Jurisdiction will be the Canadian Forces Fire Marshall.

Attack Side - The side of the door or wall that is exposed to the adversary.

Base-line Threat - Threat(s) that are common to government departments in Canada under normal security conditions, as specified in the Operational Security Standard on Physical Security.

Day Door - A door to a secure room or vault with a primary lock which when unlocked in the morning by the person responsible is still secured by a secondary lock (usually electronic access control) which can be opened (until the primary lock is re-locked) by authorized assistants.

Design-Basis Threat (DBT) - The threat(s) which the specific protection measure (equipment, procedure or policy) is designed to mitigate. Unless specified otherwise, RCMP protective designs and guides are meant to mitigate a DBT based upon the Base-line Threat.

Compromise - The unauthorized access to, disclosure, destruction, removal, modification, use or interruption of assets or information.

Hinge Pair - Industry practice is to specify hinges by pairs. For example, doors with 3 hinges are specified as “1½ pair”.

Maximum Security Pin - A hinge pin that has been fixed after insertion by welding, pinning, or other permanent means to prevent hinge pin removal without the use of special tools. Set screws are not permitted. Affords greater security than a Non-Removable Pin. (ref.: ANSI 156.1 (2006)).

Non-Removable Pin - A hinge pin secured by a set screw or other equivalent means (ref.: ANSI 156.1 (2006)).

Open Shelf Storage - Storage other than in approved security containers and safes. Open shelf storage includes storage where records are kept in containers or commercial fire and/or water resistant containers.

Safety Stud - A projecting member on one surface of a full mortise leaf that engages a hole in the opposite leaf when the door is closed. (ref.: ANSI 156.1 (2006))

Security Container - A totally enclosed container or specially designed room functioning as a storage container (e.g.: Secure Storage Room).

Secure Room (SR) - Term used to denote a room constructed to specifications of the RCMP Guide G1-029. Although not an RCMP-endorsed practice, these rooms were commonly constructed to create security zones, secure working rooms (or suites), as well as for secure storage (the original intended application).

Secure Storage Room (SSR) - The formal term and abbreviation used to identify a room which is designed to the specifications of the RCMP Guide G13-01.
Note: The term “Secure Storage Room” does not automatically replace the term “Secure Room” (level 1 or 2). Existing Secure Rooms should only be referred to as Secure Storage Rooms (SSRs) if they are actually being used in a manner consistent with this guide.

Threat and Risk Assessment (TRA) - A consideration of the assets and the threats to those assets in consideration of the sum of the security measures in place or anticipated. The RCMP and CSEC have jointly developed and promote the use of a formal procedure, checklists, valuation tables and associated training for conducting a TRA in the Federal Government called the Harmonized Threat and Risk Assessment (HTRA).

Vibration Detector - A system of one or more sensors to detect vibrations created by impact and powered cutting tools. Approved systems have a sensitivity / detection algorithm to ensure that ambient and incidental noises or vibrations due to normal activity will not initiate false alarms.

Zones - Defined in Reference B.

PART I (For use by the Department or Agency)

Advances in portable tool technology have changed the nature of overt force and skilled force attacks. In addition, large-capacity memory devices can now store significant amounts of information and the threat to personal information has greatly increased due to identity theft.

In light of these technological and threat evolutions, it is recommended that a TRA be conducted on all existing Secure Rooms (or similar spaces constructed using previous G1-029 version specifications) to determine if modifications are warranted.

Significant Changes introduced with the G13-01:

  • There is an emphasis on the Secure Storage Room (SSR) as a special type of approved security container (essentially an alternative to using numerous approved security containers) and on its application consistent with that design premise. The name has been changed from Secure Room (SR) to Secure Storage Room (SSR) to further emphasize the design intent.
  • In the past, Secure Room levels (1 or 2) were determined essentially by the choice of metal used in the walls. This guide now permits the selection of one or the other based on cost, availability and construction preference.
  • Windows and false ceilings are not part of the Secure Storage Room design and are highly discouraged. When they must be used, compensatory measures will be required. The RCMP can provide guidance on a case-by-case basis.
  • There is a new emphasis on the early detection of forced entry.
  • This guide attempts to optimize the use of commercial-off-the-shelf (COTS) material and components. Widely accepted commercial standards are referenced whenever practical.
How to Use This Guide

This Guide (particularly Part 1) is intended for use by qualified security practitioners and departmental security staff to select appropriate Secure Storage Room features and Intrusion Detection System (IDS) components and develop a Statement of Requirements (SOR) to guide the designer responsible for its design and construction.

Process

Once the SOR is established, appropriately cleared architects, engineers or qualified builders/ designers should be engaged to develop detailed drawings and specifications. These should incorporate the features and components specified in the SOR and ensure the design conforms to overall project requirements (where part of a larger project) and all applicable codes and facility “fit-up” standards. IDS design and installation should ideally be done by departmental security personnel. Departments without alarm and intrusion system sections should engage an independent (without ties to vendors or installers) consultant to assist with developing the IDS architecture and help manage the contract and procurement process. They can also be helpful with developing commissioning criteria.

The rationale for any component or feature selection (as well as the nature of the asset and the design-basis threat) should only be divulged to the architect, designer and contractor on a need-to-know basis and only if they have the appropriate security clearance. Consideration should be given to classifying the rationale and key security features.

Note: The fact that a SSR may store classified information does not in itself imply the SSR construction details should have the same classification. It does imply the construction details (as well as purpose and name of the SSR) should be adequately protected.

Segregation of details and distribution on a need-to-know basis will often be sufficient. The architect or designer should be provided with formal guidance / direction on the preparation of drawings for tender or sub-trades to ensure that sensitive information is not inappropriately divulged. For example, the purpose or name of the room should not appear on widely disseminated drawings, specifications or other contract documents. A generic or numeric name should be used. Sub-trades should receive only enough information to perform their work (eg: partial building drawings and system schematics which do not identify adjacent activities or security-related system details). Security requirements should be incorporated into contract documents where feasible to ensure enforceability.

Purpose of the Secure Storage Room

A Secure Storage Room is intended to function as an approved storage container for open-shelf storage of a large amount of classified or highly sensitive non-national (Protected) information or assets. A Secure Storage Room is essentially a “security container” and subject to the same zoning requirements.

Unless all mandatory technical and application specifications in this Guide are met, the room does not qualify as an approved Secure Storage Room (SSR) and should not be referred to as an SSR.

Fire Protection

Fire requirements (legislation) ALWAYS supersede security requirements (policy) so good planning and early consultation with the local AHJ is very important to avoid issues which may result in the removal or modification to security features.

Sprinklers are not an integral component of a Secure Storage Room and should not be added inside an SSR unless required by the AHJ. If additional fire protection is required, records can be stored in commercial fire rated containers placed inside the Secure Storage Room. Inert gas fire suppression systems can also be used.

Additional or Type X drywall sheets can be installed to meet code requirements (or as required by the AHJ). If necessary, an appropriately labelled fire door can be used instead of the specified door. Please note that there are specific requirements for mounting locks and hardware on fire rated doors. Contact the local AHJ for assistance and guidance on fire and safety issues.

Slab-to-Slab

Secure Storage Room walls must be slab-to-slab (from the finished floor to the underside of structural concrete roof or floor) or continue across the ceiling to form a continuous secure enclosure (Secure Ceiling). Where the space above the Secure Ceiling (measured to the underside of the limiting structural component) exceeds 6 inches, the space should be closed and secured or electronically monitored. In rare cases, the floor may also need special treatment. Consult the RCMP for advice.

Design-Basis Threat and Secure Storage Room Design Premise

Secure Storage Rooms primarily protect against surreptitious attacks but also detect and delay forced entry. The SSR is designed for location in a Security Zone or High Security Zone in a federal government building (or CISD-approved equivalent in contractor facilities) in urban centres. SSR constructed in remote locations may require additional safeguards.

A Vulnerability Assessment should be conducted to determine if a potential adversary can access the perimeter (or any space above or below) of the SRR undetected and unobserved for long periods of time. If so, additional measures are required to limit access or actively monitor activity in the perimeter areas.

Floors and ceilings are assumed to be constructed of highly intrusion-resistant materials such as structural concrete, reinforced concrete block or concrete on steel (roofs and floors). Wood or steel assemblies should be steel-strengthened and vibration-monitored the same as the walls.

Vestibules

A vestibule was included with the original Secure Room design for two purposes: to limit the swinging motion of hand tools and to provide better sound isolation at the door. With respect to the first objective, the most viable forced entry threat to the SSR door and hardware is now from powered portable tools and a vestibule does little to reduce it. In fact, a vestibule now becomes a possible space for an adversary to hide while attacking the door (or the wall around it). The vestibule is also not needed to enhance sound isolation at the door when the SSR is used as intended – as a records storage room.

Therefore, exterior vestibules are not required (though still permitted) for construction of a SSR. Any vestibule that is built should be constructed so as to permit observation of activities within it (eg: glazed walls or door).

A “day door” function is facilitated by use of SEG-listed locks which provide this function where departmental policy accepts the practice. To be approved for this function, the electronic access controls must work only when the mechanical lock is “open” (locking the mechanical lock must mechanically disengage the electronics so that attacks by compromising the access controls are not possible).

Well-defined and enforced operating procedures are necessary when using “day doors”. Users must not be permitted to use the electronic locking mechanism in place of the mechanical lock for extended periods (especially overnight and weekends).

Intrusion Detection Systems (IDS)

While the sheet steel on the walls provides some force resistance, its main use is to transmit vibrations from force attacks to vibration sensors. The RCMP has tested and approved a vibration detector for SSR walls which is listed in the SEG. Detection systems (e.g. motion sensors) located inside the Secure Storage Room may also be employed, although they do not detect the adversary until he/she has already gained entry, thereby reducing the available response time.

The selection table suggests what type of detection system should be used for various situations. In all cases, the alarm systems must generate reliable, timely and appropriate response.

Plumbing and Electrical Pass-through Construction

Minimize plumbing and electrical pass-throughs in SSR walls where possible. Do not locate pass-throughs in the Critical Attack Area. Where pass-throughs are required, frame openings within 1 inch (25mm) of the pipe/conduit and secure to the stud framing at minimum two places. Extend the wall protection material to within ¾” (20 mm) of the edge of the opening. Extend gypsum wall board to the edge of the pipe or conduit. Seal all gaps with fire rated or acoustic sealant. Recommended product standard: ASTM E 814 (UL 1479) or CAN/ULC S115, or as required by the AHJ.

Where necessary to accommodate pipe or conduit movement or expansion, pipes and conduit may be enclosed in a close-fitting sheet metal sleeve and the sleeve mechanically fastened to the stud framing at two places (minimum). Clearance between the sleeve and pipe or conduit should be kept to a minimum and not exceed ¼”.

Steel bars should be installed to delay access of a person through a duct with a cross-sectional area greater than 96 square inches and a smallest dimension greater than 6”. They may be omitted if a TRA determines that unauthorized entry through these ducts is not a threat.

Note that Man Bars do not prevent the introduction of deleterious material (e.g. water, toxic fumes). If a TRA identifies such threats as viable, all ducts and openings may require additional mitigation measures (e.g.: filters or dampers). Contact the RCMP for advice.

Door Locks

A code-compliant (single motion, single action) door lock that accepts approved combination locks has been approved and is listed in the SEG.

Two-Person Integrity

Some SEG-listed electronic combination locks permit the application of a two-person integrity (both persons must dial the lock open) policy. This is one of the most effective security measures that can be applied to sensitive information storage.

Screws

Screws (including “security screws”) are not approved for attaching wall protection material (steel sheet or mesh) to steel studs. Wall protection must be attached by welding or rivets.

Standard drywall screws are permitted for attaching gypsum wall board over steel protection sheeting to metal or wood studs.

Self-tapping sheet metal screws are permitted for attaching anti-spread and cross-bracing to metal studs.

Use minimum 38mm (1-1/2”) long #7 (or larger) wood (not drywall) screws spaced at 300mm o.c. (with appropriate washers) to attach steel protection material to wood joists or wood studs.

Statement of Requirements

Where the department (client) is not also the designer, a Statement of Requirements (SOR) should be developed to tell the designer exactly what is required and to identify selected construction options from those presented in the General Specifications in Part II.

The SOR and all documentation leading to the selection of SSR specifics should be considered sensitive and treated accordingly.

Do not tell the designer why a selection has been made unless the designer has a need to know.

Table 1 Security Recommendations
Sensitivity Security Measures
Protected A
Protected B

SSR not required. “Lock-Up” the information (see reference F)

A storage room constructed in close conformance to this guide will greatly exceed the minimum “lock up” physical security requirements. The following are recommended alternatives for SSR for storage of Protected A/B:

  • ½” plywood instead of sheet or mesh steel
  • UL 634 door contact and IDS (where recommended in TRA)
  • ANSI 156.13 Grade 1 mortise lock with UL 437 High Security (keyed) Cylinder
Protected C

Non-Life Threatening

  • Locate SSR in Security Zone
  • Vibration detection on walls (and Secure Ceiling if applicable)
  • IDS inside the SSR
  • Consider additional compartmentalization 1
  • SEG-listed combination locks approved for Top Secret / Protected C, OR
    SEG-listed locks approved for Secret (if supported by the DSO)

Life Threatening

  • Locate SSR in High Security Zone (exterior constructed as recommended in TRA)
  • Vibration detection on walls (and ceiling or floor if applicable)
  • Motion detection (or other IDS) inside the SSR
  • Additional compartmentalization 1,2
  • Two-person authentication 3
  • Formal TRA to ensure the adequacy of measures
  • SEG-listed combination locks approved for Top Secret / Protected C
Confidential

Locate SSR in Security Zone

  • otion detection (or other IDS) inside the SSR
  • Keyed mortise locks. ANSI/BHMA 156.13 Grade 1 or select from SEG
  • High Security Cylinders: UL 437, ANSI 156.30 Level “A” or ANSI 156.5 Grade 1A 4
  • Commercial electronic keypad locks are permitted but ‘scramble’ keypads are preferred. Specify ANSI/BHMA A156.30 level “B”(minimum) or UL 1034
Secret

Locate SSR in Security or High Security Zone

  • Vibration detection on walls (and floors or ceiling if applicable)
  • Motion detection (or other IDS) inside the SSR
  • SEG-listed combination lock
Top Secret

Locate SSR in High Security Zone

  • Vibration detection on walls (and Secure Ceiling if applicable)
  • Motion detection (or other IDS) inside the SSR
  • Consider additional compartmentalization for need-to-know 2
  • Consider two person authentication 3
  • SEG-listed combination locks approved for Top Secret
  • Formal TRA to ensure the adequacy of all storage, alarm and response measures

Table Notes

1  UL 687 labelled Burglar Resistant safes provide significant additional force resistance (as well as compartmentalization for need-to-know segregation). Although the Secure Storage Room provides early detection and some delay, the safe’s resistance time should closely correspond to the assured response time for an appropriate response.

2  Additional compartmentalization is recommended where the need-to-access principle is still a concern (see Reference B paragraph 7.6.7). Information can be compartmentalized by using commercial locking containers/cabinets. UL 437 high security keyed locks are recommended.

3  Procedural and/or technological mitigation measures should also be considered.

4  Consider the use of High Security cylinders with “chip technology” (e.g. CLIQ ™) for audit purposes (only).

General Notes:

A)  Where a TRA determines that a particular threat is well-mitigated by other aspects of security the DSO may decide that one or more of the recommended measures are not required.

B)  The Communications Security Establishment of Canada (CSEC) requires certain equipment to be placed in a Secure Room (previously the SR-2). Additional security features such as emanations protection may be required, but the RCMP can only advise on the construction of a Secure Storage Room as designed for records storage. Contact CSEC Client Services: comsecclientservices@cse-cst.gc.ca

Frequently Asked Questions

Q1: Why does Protected “C” in a Secure Storage Room still require a safe?

A1: The nature of the threat to Classified information differs significantly from the threat to Protected “C” (especially Life Threatening) information. Secure Storage Rooms are an alternative to approved security containers and must provide at least the same protection. Protected “C” (especially Life Threatening) is considered susceptible to sustained force attacks by a motivated adversary and thus needs significant force resistance. This can best be assured by using UL 687 Burglar Resistant safes with at least a 1 hour rating for the additional compartmentalization. Safes also provide additional compartmentalization for need-to-know.

Q2:  How do the Secure Storage Room requirements relate to those for a Secure Server Room as specified in G1-031?

A2:  The functions of the rooms are different. Secure Storage Rooms are designed for the storage of records. They are not intended for the processing of information (or for occupancy). Servers are vulnerable to different threats than stored records, and server rooms generally have extensive electrical, air conditioning, vents and ducts, and other systems in the room (and through the walls).

Q3: The Operational Security Standard on Physical Security says Confidential information can be stored in an Operations Zone. Why does Table 1 recommend that the Secure Storage Room for Confidential information be in a Security Zone?

A3: The Secure Storage Room should be in a Security Zone because of the elevated risks associated with storing large amounts of information on open shelves. The “periodic monitoring” requirement for an Operations Zone does not provide assurance that an adversary will not benefit from long periods of unmonitored activity. The concern is that without effective 24/7 monitoring, an adversary could gain access and operate without detection for an extended period of time. Access might be by insecure ceiling spaces or by un-alarmed/ un-monitored exit doors or elevators. If a TRA reveals that the Operations Zone is sufficiently secure that unauthorized access is highly improbable, then the DSO may permit a Secure Storage Room to be located there.

Q4:  The space assigned to us for a Secure Storage Room is adjacent to a public space or non-departmental occupant. What should we do?

A4:  A Secure Storage Room should never be placed against exterior walls other than those made of reinforced concrete or reinforced concrete blocks (all voids filled). Secure Storage Rooms can normally be placed adjacent to subterranean (basement) walls and walls at least 3 storeys above an accessible surface (ground or roof) without additional safeguards.

Double door locking bar arrangement described in Q&A 5

Q5:  We have an existing double steel door and would like to keep it for our Secure Storage Room as it makes it easier to use a forklift. Can we use it?

A5:  If the door and frame meet the basic construction requirements of this Guide you may be able to secure one of the doors to provide satisfactory security when closed and secured. One way to do this would be to install heavy duty locking bars at the top and bottom that can be secured with padlocks (to ensure users do not open them and leave them open). The bars should have a diameter of at least 30mm and be connected to the door with two guides that are welded or riveted to the door and spaced at least 300mm apart. The bars must project at least 30mm into a pocket or guide welded or riveted to the frame or secure wall. The bars should have a design that prevents unlocking when the padlock is attached.

This approach requires strict adherence to policy and procedure and should be used with discretion. A custodian should be appointed to hold the keys to the padlocks and be responsible for ensuring the secondary door is secured.

Q6:  Are there any restrictions on wall switches or outlets on Secure Storage Room walls?

A6:  The Secure Storage Room walls were tested without holes or penetrations. Surface mounted fixtures should be used where possible. Where a fixture must be set into the wall, it should be located as far as possible from the door. The fixture box must be steel and welded or riveted to the steel wall sheathing. All cables and wires should be encased in steel/EMT conduit.

Through penetrations are to be avoided. Where penetrations must be made on both sides of the wall, they should be offset at least 300mm from each other.

Q7:  The G13-01 uses mandatory language with words like “required” but isn’t it a ‘guide’?

A7:  As Lead Agency, the RCMP is delegated the authority to design, test, evaluate and approve security equipment. Each department or agency has the authority to decide if it will use RCMP approved equipment or designs – either as approved or modified in some way. To be approved, a Secure Storage Room must be constructed to the RCMP design specifications. If all RCMP specifications are not met, it is not an RCMP approved Secure Storage Room and should not be referred to as a Secure Storage Room (SSR).

Q8: What if the AHJ requires the SSR to have two means of egress?

A8:  This should not occur when the room is kept to its original design purpose as a (relatively) small records storage room since the secondary exit is determined by occupancy and floor area. If this situation arises, the second exit door should not have any locking hardware on the outside.

Q9: Can I build an SSR in a wooden building?

A9: The SSR was designed for location in a Security or High Security Zone within a typical government building in an urban environment. For other situations, conduct a TRA taking into consideration the threat, the asset and the sum of all protection measures (e.g.: location on a military base, regular patrols and fast response, etc.). While not explicit in this guide, operational security measures that are sufficient and assured can offset minor gaps in the level of physical protection afforded by wooden floor and ceiling construction. Metal protection material and vibration sensors should be installed on both the floor and ceiling of an SSR constructed in a wooden building – contact the RCMP for additional guidance.

Q10: We are putting in an enforcement unit in a warehouse bay with a main floor and a mezzanine floor that will be open to the main floor. However, there will be enclosed offices on this floor. There are plans for two evidence/secure storage rooms on the main floor underneath the mezzanine floor. The floor will not be slab concrete. What should we do?

A10: Where the roof (mezzanine floor) is made of wood (wood or composite joists with plywood sub-flooring), we recommend that the roof have expanded metal mesh (3/4" - #9F as called for in the wall construction) secured to the underside (secure side) of the roof joists and a vibration detector (sensor) installed in contact with the mesh on the secure side. The sensor mounting plate can be installed adjacent to the roof joist (preferred solution). Cabling for the roof sensor should be run on the secure side of the SR ceiling (i.e. in surface mounted conduit) to where it joins the other sensor cabling in the common conduit to the alarm control panel.

Q11: Can I install the door lock at a different height to accommodate accessibility requirements?

A11: Ordinarily installing the door lock 44 inches above floor level will accommodate accessibility requirements for all users. If the lock is being installed less than 42 inches above floor level, the anti-spread bracing (between the door frame and adjacent stud – located 48 inches above the floor) should be lowered to within 6 inches of the lock center-line, or additional anti-spread bracing installed 6 inches or less below the lock center-line.

Q12: Can I change the lock height (e.g., to accommodate a handicapped person)?

A12: Yes. If the lock height is shifted more than about 150mm (6”) we recommend also shifting the anti-spread bracing to match.

PART 2 - SSR Construction Specifications

Construction: Laminated core with vertical steel stiffeners at 150mm oc (stiffeners welded or laminated to each face sheet with voids between stiffeners filled with fiberglass or mineral batt type material).

Caps: ‘Flush Closing Channel’ or ‘Flush Channel’ top and bottom.

Ref: NAAMM 810-09 Part 2. A. Figures E and F for edge details.

Edges: all edges and top and bottom caps to be continuously welded and ground smooth.

Door handing: (must be specified as per client requirements).

Frame:

Gauge: 16 gauge (1.6mm) steel

Frame construction: Welded or fully field welded 3-piece “knock-down” (for retrofit applications).

Anchors: “Z” shape steel wall anchors welded to frame.

Reinforcing at latch: as per lock manufacturer recommendations. Lock specifications must be provided to the supplier/manufacturer to provide necessary reinforcing requirements.

Locks: Select according to Table 1.

Hinges: to ANSI/BHMA A156.1 Grade 2 and ANSI A8112 (Steel Material Standard)
Full mortise, five knuckles, ball bearings, standard weight. Three (3) hinges per door (minimum).
Minimum Dimensions: 114mm (4 ½”) x 114mm (4 ½”) x 3.4mm (0.124”) thick.

Hinges mounted with barrels on the attack side (“reverse-hung” or outwards opening) must have non-removable pins (NRP), maximum security pins (MSP) or safety studs/reverse safety studs. Note that these require special ordering instructions.

Suggested products:

Door closer: Overhead style ANSI A156.4 Grade 1
Suggested product: Ingersol-Rand LCN 4040 series

Threshold: Aluminum (or other metal) interlocking style with hook strip installed on door.
The SSR should qualify for exception from building code “Barrier-free path” requirements when used only to store records. However, where wheelchair accessibility is required, two recommended products are:

Door contacts: UL 634 High Security Switch - level 1 or level 2.

Door installation: The door is generally installed as regular hung (opening into the Secure Storage Room), but it can be reverse hung (opening out) in exceptional cases.

Frame reinforcement at the lock area (Figure 7):
Secure a 6.4mm x 25mm x 610mm steel plate inside the frame using tack welds on every edge. Align the centre of the plate with the lock bolt.

For reverse hung doors, install a steel astragal covering the entire lock edge of the door AND the unmodified strike plate. The astragal should be at least 14 ga (2 mm) thick, should overlap the door frame by at least 25mm. Attach with minimum 6mm (1/4") diameter steel carriage bolts spaced at 250mm oc and at least 25mm from mortise lock pocket. Carriage bolt heads must be on the attack side.

Suggested product: Zero International #43STST
