Lab Restraints.NZ



Lab Restraints.NZ is a subsidiary of Disaster Prepare Ltd specialising in seismic restraints for Laboratories with extensive experience in PC2 & PC3 Labs with some PC4 work.

Areas of expertise

Our services are aligned with the HSWA defined risk management processes guiding our clients on a pathway to meaningful safety improvements and HSWA compliance.

Initial Seismic Safety Assessment

Assess building contents based on NZS-4104 “Seismic Restraint of Building Contents” requirements.

Seismic Restraints

Install NZS-4104 compliant seismic restraints to protect expensive Lab equipment, ensure bio containment and HSWA compliance. Solutions include custom cables and our new Seismic-Rail-System. Traffic light quality control stickers are fitted to restrained items to visually identify their hazard mitigation status.

Project Consulting

We engage with clients in the planning stage to avoid costly seismic remedial action. Example specifications include:

  • Ensure benches are engineered to withstand seismic loading of the heavy items braced to them
  • Ensure flexible gas, water and drainage fittings fixed to Lab equipment
  • Wall design to withstand seismic loading of equipment braced to them
  • Large specialist floor mounted items braced by equipment supplier during installation

Compliance reporting

Project completion and exception report provides a record of completed works for compliance reporting. Exception reporting identifies additional items that require seismic restraints particularly where works are being conducted in multiple phases.

Some of our innovative lab restraint solutions

Bio containment floor penetration solution

Tall heavy items such as large freezers restrained to walls can cause significant damage to walls during a large quake. They should be braced to floors to ensure the safety of your team. Corrosion resistant 316 Stainless-Steel drop-in anchor fitted with silicone seals between the floor and the Eye Bolt to ensure a watertight seal and mitigate bio containment issues.

When equipment is removed the eye bolts are replaced with cap screws and silicon seals to prevent liquid ingress under the floor covering. This also eliminates potential trip hazards.

Seismic Rail System©

Our new Seismic Rail System© provides a flexible quick release solution to enable Lab staff to reposition Lab equipment as needed, eliminating single use adhesive Lab restraints. Bench top or wall mounted. They span the full length of all Lab benches to provide maximum flexibility for equipment placement.

They can also be wall mounted for tall free-standing items as seen here.

Custom Cable Solutions

We design and manufacture custom cable solutions on site to ensure a perfect fit. Cable solutions range from heavy duty cross bracing for bio safety cabinets to unobtrusive quick release mini cable restraints for microscopes.



Seismic restraints can take many forms, including anchors, braces, and straps. They should be installed by qualified professionals who have experience with seismic restraint systems and who can ensure that the restraints are properly designed and installed.
